Summary of The Transactions – The 1970s
The 1970s, were years of relative prosperity in the mining industry, although it was not entirely free from problems. The threatened closure of Wheal Jane, led to a protest march of miners to the Houses of Parliament. Meanwhile the china clay industry was actually employing its largest ever workforce of about 6000, in 1970. The engineering companies which supported the extractive industries shared in the good times although the changes in the industrial landscape of the country meant that it became increasing difficult during the decade.
The Transactions( Vol. XXVI) had no introductory remarks. In this session there were six General Meetings plus the AGM. The first General Meeting was an excursion on 19th September 1970, when there were visits to three premises in Falmouth and one in Pool. In the morning visits were paid to J.H. Loke & Co., Printers, Lockwood Machine Tools Ltd., and K.P. Merritt. Lunch was taken at the Norway Inn at Perranarworthal before visiting South Crofty Mine at Pool. At the end of the excursion tea was taken at the Moonraker Restaurant, Redruth where Mr. Polkinghorne Presided.
The second General Meeting was a film evening on 23rd October when thee films were shown: “Riverside” Courtesy of Whimpey Construction Ltd.; “Cobar – A New Era in Mining” by courtesy Austral Development Ltd. and Borehole and “Borehole Investigation by Television” by the Hydrogeological, Department, Institute of Geological Science.
The third General Meeting on 18th November, was chaired by Mr. R.H. Stapleton, Vice-President and it heard a lecture on “Flocculation with High Molecular Weight Polyelectrolites”. The paper was not printed in the Transactions.
At the fourth General Meeting on 17th January 1971, the President, Mr. J.P.R. Polkinghorne congratulated Mr. J. H Trounson, Past President and long serving Honorary Treasurer on his award of an MBE. He also congratulated Mr. Shrimpton, Honorary Secretary on his being elected as President of the Royal Geological Society of Cornwall.
The President then invited Mr. T. H. Harriston to deliver his talk on “A Short History of the Cornish Explosives Industry”. This “short” history was in fact quite a comprehensive account of the manufacture of gunpowder and other explosives from 1824 until the final closure of the Herodsfoot factory of Burrowite Explosives Ltd. following a disastrous explosion in 1963. The speaker gave details of the various places where firstly gunpowder then high explosives and also described several accidents including several where fatalities occurred. He also described the invention of the safety fuse and a history of the the Bickford Smith factory at Tuckingmill.
There was a brief discussion following the talk and both are fully reported in the Transactions.
The fifth General Meeting on 24th February heard a lecture by Mr. J.L. Burgess, Technical Service engineer at Holman Bros. Ltd. on “Noise – Its Measurement, Suppression and Control”.
He started by defining noise and the range it covers from very faint with sound pressures of .0002 dynes/sq. cm. Levels are expressed in dB above the minimum discernible with anything of 120dB and above being described as dangerous.
He then described noise measuring instruments and their use before discussing the causes of noise in various types of machinery. Methods of suppressing that noise was then described and the recognition that in some cases suppression is impossible when the use of ear defenders may become necessary.
The talk was followed by a discussion in which a number of members took part. The paper and discussion are both reported in the Transactions.
The sixth General Meeting on 9th March was given a talk on “The Application of X-Ray Fluorescence Analysis to the Mineral Industry” by Mr. G.C. Edgley of Nuclear Enterprises Ltd.
The lecture was not printed in the Transactions.
Annual General Meeting, 23rd April 1971
The President opened the meeting by asking Mr. G.J. Shrimpton to present the Council Report.
Of the seven meetings, the first was the visit on 19th September which took in four locations (these are described earlier in the Transactions) and the second meeting was a film evening. The attendance at the meetings was generally between 40 and 50.
No entries had been received for a William Thomas Memorial Prize.
The membership stood at 115 Members, 25 Associates and 3 Subscribers. Seven Members had been elected during the session. The deaths of two members were noted with regret, four had resigned and six had been removed from the membership list by default, presumably subscription related.
Elections. Mr. R.H. Stapleton was elected President for the 1971/72 and 1972/73 sessions and Mr. G.J. Shrimpton was elected Vice-President and Messrs. F. Hutchin and G.J. Shrimpton were re-elected as Joint Secretaries.
Mr. J.H. Trounson was re-elected as Honorary Treasurer and Messrs. G.E.P. Roberts and B.O. Rees were re-appointed as Auditors.
The Fourth Biennial Dinner would be held at the Basset Count House, Redruth on May 26th, when the new President, Mr. R.H. Stapleton would take office.
The President then asked Mr. F. Hutchin to present the financial report for 1970. Mr. Hutchin said the statement would be under the usual three headings: The General Account at Barclays Bank, the Union Trustee Savings Bank Account and the William Thomas Memorial Fund.
The balance in the Barclays Bank account had a balance of £161/14/10 on 1st January. The income from subscriptions was £151/1/6, the sale of Transactions amounted to £20/7/6, the Summer Meeting £2/7/6 and £150 was transferred from the Trustee Savings Bank account.
Expenditure amounted to £426/12/8 the main item being for printing Volumes XXII, XXIII and XXIV of the Transactions although general expenditure had also shown a significant increase and the balance on 31st December was £54/18/8.
In view of these increases the Council recommended an increase in subscriptions under the Institute By-Laws, Section II paragraphs 2 and 5 of the Constitution.
The Union Trustee Savings Bank account had a balance on 1st January of £402/12/-. Interest amounted to £24/4/9 and £150 was transferred to the CIE general account leaving a balance of£282/16/9 on 31st December .
The William Thomas Memorial Prize Fund showed an increase of £2/19/2 due to interest received and the fact that no prize had been awarded. The balance on 31 December was £101/17/1.
After the Council and Financial reports had been accepted the formal business was complete and the President invited Mr. M. Grieves , Mining Division of Thysson, (GB) to deliver a lecture on “Planning for Power”. At the end of his talk he gave a review of progress on the shaft sinking operation at Boulby in the Yorkshire Potash Field. His talk was not printed in the Transactions.
At the end of the fourth Biennial Dinner on 26th May the President, Mr. J.P.R. Polkinghorne formally handed over to his successor, Mr. R.H. Stapleton.
Volume XXVII Transactions had no editorial introduction but noted that the programme would consist of ten General Meetings plus the AGM.
At the first General Meeting on 29th September 1971, Mr. Stapleton delivered his Presidential Address on ”Compressed Air Transmission, Storage and Use in Mines.”
He said his paper outlined some of the problems met in providing an efficient compressed air supply and it dealt with leakage, auto compression, and the importance of supplying dry air. He said that in many cases rock drills were operating at only 60% of the design pressures. He gave an example of tests carried out at a mine which used 18,500 cubic feet per minute in a system with 16,000 feet of of surface mains pipes and 78,000 of underground piping. Leakage was found to be 32% of the total compression point output. He said the most common causes of of leakage are defects in valve glands, pipe joints, hose connectors and supplies left on for environmental conditioning. He then described methods of storage, pipe distribution systems by which losses could be reduced in these areas.
The second General Meeting on 3rd October, heard a lecture by Mr. N. Wallen, Sales Director of Craelius, who had flown over from Sweden to give the lecture as Mr. Whitehead, Managing Director of Craelius (UK) had been injured in an accident.
The talk was entitled “Diamond Drilling Machines, Methods and Costs”. Mr. Wallen described the use of diamond drills and said that, in general, development of diamond drilling machinery had been static for many years except for one new drill developed by Atlas Copco. He then described the drilling techniques and types of bits used before describing the Atlas Copco machine method of use.
The lecture and the following discussion were both printed in the Transactions.
The third General Meeting on 10th November, was given a lecture by Mr. C. Harries, Fuel Development Engineer, Shell Mex-BP Ltd. on “Total Energy”. He said the purpose of the paper was to indicate the factors influencing the concept of “Total Energy” including prime movers, fuels and the price structure of the public supply system.
He defined Total Energy as the production of the energy requirements of a plant, building or factory by optimum use of the available heat from a fuel source. He went on to describe the price structure of the Public supply in the U.K. at that time, the choice of prime movers for the generating plant and the availability of fuels. He then gave examples of the way Total Energy is calculated and the ways in which the use of energy could be made more efficient.
The lecture was followed by a discussion in which a number of contrary opinions were expressed and this was printed in the Transactions along with the lecture.
The fourth General Meeting on November 24th was given a talk by Messrs. T. Powell and J.F. Michell on “The Application of Rubber in the Mining and Quarrying Industries as an Abrasive Resistant Material.” The talks were not printed in the Transactions and there was no mention of any discussion.
The fifth General Meeting was held on 8th December with a talk on “Bearing Failure Prevention by Shock Pulse Measurement” by Mr. D.E. Butler, Special Products Engineer, Skefko Ball Bearing Co. Ltd. He said that roller bearing manufacturers place a nominal life value on products but it was an expectancy, not a guarantee because various types of failure can occur to shorten life but down time can be avoided by detecting faults in their early stages and this can be done by a shock pulse method of assessing bearing condition. Defects in the inner and outer rings and in the rollers themselves give different responses to shocks which are administered, in the SKF system, at a frequency of 38Khz.
He gave two examples of interest; in one case indications in a fan were ignored and the bearing collapsed ten days later. In the second case two grinding machines out of thirteen were diagnosed as defective and the bearings changed and so avoiding possible catastrophic failures.
There was a discussion which was reported in the Transactions along with the talk.
On 26th January 1972, the sixth General Meeting had a talk by Mr. G.W. Whitmore on “Compressed Air Drying”. It was not reported in the Transactions.
The seventh General Meeting on 9th February, heard a lecture on “Reinforced Concrete Silos and Storage Bins” by Mr. D.F. Evans, Contracts Manager, Holst & Co., (South Wales) Ltd.
The paper concerned the reinforced concrete silos recently constructed at South Crofty. He described some design aspects and discussed some alternatives such as structural steel and then gave the reasons for using reinforced concrete.
The nest of three Crofty silos are 70ft. high and 25 ft inside diameter with a capacity of 1500 tons for ore straight from the mine. The smaller nest of two each of 1000 tons capacity are 90ft hight with a 30ft inside diameter.
He concluded the talk with a description of the construction methods used. This talk was printed in the Transactions but there is no mention of a discussion.
The eighth General Meeting was cancelled owing to the emergency and lighting regulations then in force.
The ninth General Meeting on 8th March heard a talk by Mr. T. Atkinson on “The Repair of Electrical Plant.” which was not reported in the Transactions.
At the tenth General Meeting on 22nd March Mr. M Grieves, Divisional Manager, Thysson (GB) Ltd. gave a talk on “Modern Shaft Sinking Techniques”. It was not printed in the Transactions.
Annual General Meeting, 26th April 1972
There was no editorial introduction in the Transactions but it was noted that there would be a programme of nine General Meetings as well as the Annual General Meeting.
The President opened the meeting by asking Mr. F. Hutchin to present the Accounts and Financial Statement for 1971. It is worth noting that since the last AGM the currency had changed from an Imperial to a Decimal system.
The balance in the the CIE General Account on 1st January 1971 was £54.93. The income from subscriptions was £190.97, sale of Transactions came to £14.06 and there was £91.80 from the Biennial Dinner.
Expenditure included the Secretaries’ salaries of £60, postage and sundry items cost £41.12 and the Biennial Dinner cost £88.50 and the balance on 31st December was £145.89.
The Union Trustee Savings Bank Account increased from £282.84 on 1st January to £299.15 on 31st December as a result of interest received.
The William Thomas Memorial Prize Fund increased from £101.85 to £105.38 since no prize had been awarded during the year.
The President then asked Mr. G.J. Shrimpton to present the Council Report.
He said that one of the ten scheduled General Meetings had been cancelled because of Government lighting restrictions and the attendance had varied from a low of 26 to a high of 90. The Dinner held at the Basset Count House Hotel, Carnkie was attend by 76 members and friends.
No papers had been put forward for a William Thomas Memorial Prize and two companies had offered to finance an award. Messrs.Wests (Manchester) Ltd., manufacturers of mineral processing machinery have offered to fund a medal for the best paper presented on a subject relating to mineral processing and Messrs. Wheeler, Crittal, Barry, Ltd., Electrical Contracting Engineers have agreed to fund a prize of £30 for a paper in the electrical or instrumentation fields. The Institute had expressed its thanks for these offers.
The Council reported that the membership stood at 135 Members, 27 Associates and 6 Subscribers, 24 Members had been elected during the year including the transfer of 4 Associates, 4 Associates were elected and one resigned
Elections Messrs. F. Hutchin and G.J. Shrimpton were re-elected as Joint Secretaries, Mr J.H. Trounson was re-elected as Honorary Treasurer and Messrs. G.E.P. Roberts and B.O. Rees were re-appointed as Auditors.
On 14th September an evening visit, attended by 30 members and friends had been made to the mill of Camborne Mines Ltd., Roscroggan and the mill at South Crofty .
At the close of the formal business the President introduced Mr. S.J. Cook, Operations Manager, Closed Circuit T.V. Equipment, Photo Scan of London who gave a talk on “Closed Circuit Television”. The talk was not printed in the Transactions.
The President for the 1972-73 session was Mr. R.. H. Stapleton and the session programme was centred on nine General meetings starting on 4th October, 1972 and ending on 20th March, 1973. There was also a joint meeting with the Devon and Cornwall Branch of the Institute of Work Study Practitioners on 19th September, 1972 for a paper on “Work Study in Mining”. Visits were made to King Edward Mine on 27th July, 1972 and Wheal Jane on 17th March, 1973. This busy session ended with the Annual General Meeting on 11th April, 1973.
Volume XXVIII of the Transactions contains only three of the nine papers, presumably to save space since these three occupy a total of 50 pages. This volume of the Transactions covers both the 1972-73 and 1973-74 sessions and is in soft bound, A4 format. The papers printed; “Ore Testing and its Role on Mineral Dressing”, “Fine Crushing of Minerals” and “The Concentration of Ultra-Fine Minerals” presented on 4th October, 1972, 25th January and 30th March 1973, are all on similar subjects but the complete list of papers presented during the session suggest that many other papers covering a broader spectrum were presented. Examples were “The Use of Resins in Rockbolting”, “Offshore Marine Mining” and “Non-Destructive Testing”, all of which might have given a more accurate impression of the range of interest of the Institute.
Annual General Meeting, 11th April 1973
The President opened the meeting by asking those present to stand in memory of Mr. G. E. P. Roberts who had recently died. He was a long serving member who had been President in 1953/54 and a joint Auditor since 1951.
Council had reported that attendance at the meetings during the 1972 – 73 session had varied between 25 and 45. No papers had been submitted for the William Thomas Memorial Prize and two papers had been entered for the first award of the new West’s Gold Medal, Mr Piggot’s paper on “Ore Testing” and Mr. Michell’s paper on “The Concentration of Ultra-Fine Minerals”. The intention was to award the medal at the forthcoming Biennial Dinner.
The membership was currently 139 Members, 23 Associates and 5 subscribers. Nine Members and one Associate had been elected during the year and four Members had resigned. Four Members and one Subscriber had been deleted from the membership list under By-Law Section II. Although the report does not say so this was presumably a result of subscription arrears.
Mr. W. E. Sevier was elected to serve as President for the 1973/74/75 sessions. Six Members were re-elected and two new Members elected to Council. Mr. G. J. Shrimpton had resigned as Joint Secretary and Mr. B. Earl was elected to join Mr. F. Hutchin as a Joint-Secretary.
The fifth Biennial Dinner was scheduled for 23rd May 1973 at the Penventon Hotel, Redruth.
Finally it was reported that Volumes XXV and XXVI of the Transactions were at the printers.
The Financial Report for the year ended 31st December, 1972 was presented by Mr. F. Hutchin.
The General Account Balance on 1st January, 1972:- £145.89 and there was an income of £365.3. Expenditure was £122.72 leaving a balance of £388.49 on 31st December, 1972:-
The Union Trustee Savings Bank account balance on 1st January 1972 was £299.15, interest was £18.01 giving a balance on 31st December 1972 of £317.16.
The William Thomas Memorial Fund had a balance of £105.38 on 1st January 1972, interest was £3.67 giving a balance on 31st December 1972 of £109.05.
Mr. J. H. Trounson was proposed by the President and duly elected to continue serving as Honorary Treasurer. Mr. Hutchin proposed Mr. B. O. Rees and Mr. A. D. Bennetts as Auditors and they also were duly elected.
As already noted the President for the session was Mr. W. E. Sevier and he presided over a slightly reduced programme of seven meetings. The first General Meeting was held at the Camborne School of Mines on 26th September 1973, and received Mr. Sevier’s Presidential address on “The Nigerian Electricity Supply Corporation Ltd”. This was one of only two papers printed in the Transactions. The second published paper was a dissertation on “Mining and Money” by Mr. Justin Brook, who was a member of the Stock Exchange. It is an interesting addition to the history of mining from the view of how it had been financed particularly since the slump of the industry in the mid-nineteenth century.
The reduced number of meetings did not signify a lack of activity since the Institute also organised two symposiums. On Saturday 7th July, 1973 an all day symposium was held at the Penventon Hotel, Redruth when the topic was “Celtic Sea Offshore Oil and Gas Exploration”. Mr. David Mudd, M.P., acted as chairman and introduced the speakers: Mr. C.R.L. Clarke, Mr. E. Hannington, Mr. H.G. Challis, Mr. A. Scott and Mr. D. E Turnbull. At the close of the meeting Mr. Mudd gave an appreciation of the papers and the President, Mr. W. E. Sevier, thanked the speakers. Mr. Mudd also attended the Tenth Annual Mining and Quarrying Symposium on 24th October 1973 which was also held at the Penventon Hotel, Redruth and he introduced Mr. Anthony Grant, M.P. who opened the symposium. Papers were read by Dr. P. Hackett, Mr. B. W. Mansell, Mr. I. S. Wells and Mr. A. T. Lovegreen. At the close of the meeting Mr. T. S. Wilson spoke in appreciation of the papers and thanked the speakers for a most interesting day. He also thanked Mr. R. H. Stapleton for his work in organisation of the symposium.
There were also two field visits. The first, on Saturday 29th September, 1973 started at the A.R.C., Penlee Quarry at Newlyn where the party of members and friends toured the crushing and screening plant, and then went on to the Post Office Radio Station at Goonhilly Downs where all parts of the station were visited. The President, Mr. W. E Sevier thanked Mr. A. Edwards , the Assistant Manager at Penlee and Mr. Welch at Goonhilly on behalf of the Institute for their help. The second visit on 20th October 1973 took in the Holman Test Mine at Troon where members inspected new drilling equipment, and then the Goonvean and Rostowrack China Clay Co., Ltd., where the new Buell -Turbo Drier and ancillary processing plant were examined. The President Mr. W. E. Sevier on behalf of the Institute thanked Mr. Harrison of Holmans and Mr. C. V. Smale for most interesting visits.
Annual General Meeting
At the Annual General Meeting on 3rd April. 1974, Mr. C. V. Smale deputised as Chairman in place of the President, Mr. Sevier, who sent his apologies. Mr. Smale then called upon Mr. B. Earl to present the Council’s Reports.
The Financial Report for year ending 31st December 1973 showed a balance in the General Account on 1st January of £388.49 and an income over the year of £341.10. Expenditure amounted to £345.98 leaving a balance of £383.61 on 31st December. The Trustee Savings Bank account showed a small increase over the year, rising from £317.16 to £339.63. The William Thomas Memorial Fund also showed a small increase from £109.05 to £113.14.
The Council reported that the membership was then 144 Members, 23 Associates and 4 Subscribers. Eight Members and one Associate were elected during the Session and there were 2 resignations. It was with great regret that the Institute had to record the deaths of Mr. S. H. Alder, a serving member of Council; Mr. C. U. Stewart, a member for many years; Mr. W. Nicholls; Mr. T. A. W. Haddon; Mr. H. L. Mitchell and Mr. W. S. Kernick, a member for nearly thirty years. The Council had also started work on a revision of the Constitution. Mr. J. H. Trounson was e-elected as Treasurer, Messrs. F. Hutchin and B. Earl were re-elected as Joint Secretaries, and Messrs. B.O. Rees and Mr. A. D. Bennetts be re-elected as Auditors. The Council report and the Financial report were both adopted unanimously and this concluded the formal business of the meeting.
Having concluded the business of the meeting Mr. Smale invited Mr. E.W. A. Edmonds to present his paper: on “The Camborne – Redruth Tramway” which was illustrated with many photographs and diagrams. At the close of the discussion which followed a vote of thanks was proposed by Mr. J. H. Trounson and seconded by Mr. J. Langford.
The programme for the 1974/75 consisted of only five General meetings, two of which were joint meetings, one with the South West England Section of the of the Minerals Engineering Society and the other with the Royal Geological Society of Cornwall. There were also two visits and a symposium. Only the two papers presented at the first and second General meetings were printed in the Transactions, Volume XXIX, which also covered the 1975 – 76 session. The fact that there were only five meetings, the last of which was a film show on 19th March 1975 suggests that the Institute was once again having difficulty in getting papers. With one exception, a paper on “The Work of the Department of Trade and Industry in the South West” presented at the fourth General Meeting on 26th February 1975, all of the papers presented at the General meetings were on mining subjects. It is of interest that the March meeting was the last held at the old building of the Camborne School of Mines in the centre of Camborne at which the Institute had been able to hold its meetings since the earliest days after its formation.
Another important item of business undertaken during this session was completing the revision of the Constitution which had been started in the previous session. The Council had agreed the revision at a meeting in July 1974 and it was adopted at the AGM on 23rd April 1975. It was printed in the Transactions and is included in Chapter ????
There was an evening visit to RAF St Mawgan on 17th July 1974, and an all-day visit on 28th September taking in the Holman Shipyard at Penzance, the Amey-Roadstone quarry at Castle-an-Dinas and the concentrator at Geevor Mine. The latter visit was attended by 60 members and guests.
The first General Meeting was on 13th November heard “Thoughts on Mineral Processing and the Significance of Mineralogical, Economic and Environmental Considerations” by Mr. F. B. Michell. The second General Meeting on 8th January 1975, heard a paper on “The History of Rammelsberg Mine” by Mr. T. A. Morrison. The papers presented at these two meetings are the only ones printed in the Transactions but both are of considerable length, the first occupied twelve A4 pages and the second 24 pages.
At the third General Meeting on 5th February, Mr. J.H. Trounson presented a paper entitled “Recent Considerations Regarding Mining Areas of Cornwall”.
The Transactions also included one of the papers, entitled “Mining Processing – Savior or Villain of Mining” delivered by Dr. E. C. Cohen at the 11th Annual Mining and Quarrying Symposium. This symposium was held at the Penventon Hotel, Redruth on 23rd October 1974. Before the start of the main business of the day the Chairman of the Cornwall Industrial Centre Trust, Mr. J. L. Bulley, handed the Trust over to the Institute. The symposium was chaired, as it had been in the previous year by Mr. David Mudd, M P.
The Cornwall Industrial Trust
The Cornwall Industrial Trust had been set up earlier in the year following the liquidation of the Cornwall Productivity Association which since 1950, had served Cornish industry and commerce by arranging lectures, symposia, conferences, courses and study groups. After consultation with member firms of the Association it was agreed that the £3,500 odd then available should be used to form the nucleus of a fund to promote higher technical education in Cornwall. After protracted negotiations, charitable status was obtained for the Trust. The objects of the Trust were the advancement of education in mining, quarrying, metallurgy, civil, mechanical and electrical engineering, and the exchange of ideas and information in those fields.
The ways of achieving these aims included:- The establishment of scholarships to assist students at the institutions of higher education to obtain technical qualifications in the specified fields, arranging meetings and symposia to receive papers, show films and conduct discussions, the giving of financial assistance to symposia intended to further technical education in the specified fields and publishing transactions and technical papers in the specified fields, either alone or in co-operation with learned societies.
The Chairman of the Trust, for the time being was to be the President of the CIE. The Secretary, Treasurer and the three Trustees were all Members of the Institute
A full description of the Trust was included in Volume XXXI of the Institute’s Transactions covering the year 1978/79.
Annual General Meeting
The Annual General Meeting was held at the Camborne School of Mines on 23rd April 1975 with the President, Mr W E Sevier in the Chair.
The Council Reported that copies of the Revised Constitution and By-Laws had been sent to all members and no suggestions for further amendments had been received. The meeting voted unanimously to adopt the revised Constitution.
The Council awarded the William Thomas Memorial Prize for 1974 to Mr. T. A. Morrison for his paper, “The Story of Rammelsberg, Mine.”
Elections for 1975/76 Session
Following the statutory ballot Mr. G. J. Shrimpton was had been nominated to be President for the 1975/76 session. This was accepted by the meeting. The Council proposals for Council Members were also endorsed.
Mr J.H. Trounson was re-elected as Treasurer. Following the resignation of Mr. B. Earl, Messrs.F. Hutchin and Mr. G.C. Barrett were elected as Joint Secretaries
Messrs. B.O. Rees and A.D. Bennetts were re-appointed as Auditors
General Account balance brought forward on 1st Jan 1974 was £283.61 and the income was £294.31. Expenditure amounted to £256.66 leaving a balance on 31st December 1974, of £421.26.
The Trustee Savings Bank Account showed an increase of £24.80 to £364.43 and the William Thomas Memorial Fund increased from £113.14 to £117.41.
The adoption of the Financial Statement and Council Report was proposed by Mr. J. H. Trounson and seconded by Mr. C. V. Smale and was adopted.
The President closed the meeting and invited Mr. E.W.A. Edmonds to present the post-AGM for the second year running. On this occasion his lecture was entitled “Electric Pumps in Cornish Mining 1900 – 1975”.
This session saw an increased programme of seven General meetings including two joint meetings, one with the South West of England section of the Minerals Engineering Society and the other with the Royal Geographical Society of Cornwall. There were also two evening visits, one to the Central Electricity Generating Board power station at Hayle and the other to Mount Wellington Mine.
The first General Meeting on 9th October 1975 was scheduled to hear Mr. G. J. Shrimpton’s Presidential Address on but it is not printed in the Transactions for this session although there is a note that it would be printed in the next Volume of the Transactions. It does in fact appear in Volume XXX of the Transactions as the Presidential Address covering both sessions of Mr. Shrimpton’s Presidency. It was entitled “A Review of Some of the Developments in Underground Mining Methods”.
The only paper printed in the Transactions was that delivered at the second General Meeting on 6th November entitled “Environmental Control and the Extractive Industries” by Mr. W. M. Whetter of ECLP. This lengthy paper was very well received and led to a lively discussion. It covered the history of the subject as well as describing the twenty Acts of Parliament since the start of the 20th Century as well as six concerned specifically with air pollution and six on water pollution. In congratulating the speaker Mr. J.H. Trounson commented that the complicated nature of recent legislation was making it very difficult for the expansion of the minerals industry. The speaker said he should perhaps have entitled his paper “The Tightening Noose”.
The dates and subjects of the other General meetings were: 13th November, ”Powder Couplings” by Messrs. Parnell, Lewis and Teuperley, 10th December,”The Role of Rubber in the Extractive Industry” by Mr. E.P. Hutson-Flynn. 15th January 1976, “Metalliferous Mineral Exploration in S.W. England” by Mr K.E. Beer. 12th February, “Cut and Fill Stoping”
In addition to the above programme the Institute also organised the 12th Annual Mining and Quarrying Symposium on 22nd October 1975 at the Penventon Hotel, Redruth. It was attended by about 60 members and guests and opened by Mr. Hawken Rowse, Chairman of the Cornwall County Council. One of the papers presented which looked as if it might be of future importance was the “Underground Oil Storage in Disused Mines Was it impracticable or Unpopular?”. The last session of the symposium was an open forum on “The Recovery of Fine Tin”
Annual General Meeting
The Annual General Meeting was held at the Camborne School of Mines on 28th April 1976 with the President, Mr. G.J. Shrimpton in the Chair.
Mr. F. Hutchin presented the Council report and the Financial Statement. The Council reported the results of the ballot for Members of Council. The following had been elected:- Messrs. C.V. Smale, B. Earl, L.J. Bullen, J. Symons, R. Pascoe, J. Brooke, G.C. Pengelly and Dr. P. Hackett. Mr. A.D. Bennetts had been elected as Second Vice-President.
The William Thomas Memorial Prize had been awarded to the only paper submitted which was Mr. T. A. Morrison’s “Cut and Fill Mining” which he had presented at the sixth General Meeting on 12th February 1976.
Mr. J. H. Trounson who had been Treasurer since 1940 announced that he thought it was time to retire and he proposed Mr. A. Travena to take his place. This was seconded by Mr. R.H. Stapleton. Mr. Travena was elected unanimously and the President thanked Mr. Trounson for his long service. Seconded by Mr. Hutchin this was carried. Messrs. P. Hutchin and G.C. Barrett were re-elected as Secretaries.
The General Account Balance brought forward on 1st January, 1976 was £421.26. The income for 1975 was £675.266 and expenditure amounted to £674.35 leaving a balance of £407.91 on 31st December.
The Trustee Saving Bank Account showed an increase from £364.43 to £391.19 and the William Thomas Memorial Fund decreased slightly form £117.41 to £116.59 after taking into account interest earned and the award of the prize to Mr. T.A. Morrison.
There were reports on two other accounts which did not appear in the previous years statement:-
The Cornish Institute of Engineers No 2 Account showed an increase from £114.50 on 1st January 1975 to £192.80 as a result of deposits made but the source of these was not given. It had been decided to close this account and transfer the money to the main account. An additional sum of £135 received in 1976 from the 1974 and 1975 symposiums would be added.
The Cornwall Industrial Trust Account had a balance of £3671.16 on 1st January 1975. Interest received was £370.68 and £365.21 received from closure of the Cornwall Industrial Centre Trust Account. A sum of £12932.38 was spent on the purchase of £4200 of 81/4 Treasury stock leaving a balance at Barclays Bank on 31st December 1975, of £1174.78.
There is no record of any discussion on either the Council report or on the financial statement although it is recorded that adoption of both the report and the financial statement was proposed by Mr. J. Symons, seconded by Mr. T. Andrews and accepted.
At the close of the meeting three technical films were shown:-
“Its All Done With Minerals”, “Testing a New Model” and “Once in a Million”
Mr. G. J. Shrimpton was President for the second of his two years term which saw a return to a truncated programme of only five meetings but it encompassed a wider range of topics of which only two were printed in the Transactions. The first was a paper presented at the second General Meeting held jointly with with the SW of England Section of the Minerals Engineering Society on “Developments in Iron Making”, by Mr. R.H. Parker. The other paper printed was on “The South Devon Ball Clay Industry” by Mr. E. Ash. There was no record of any discussion being held after either of these meetings
There is no record of any field visits during the session but the Institute also organised the Thirteenth Annual Mining and Quarrying Symposium on 3rd November 1976. The President, Mr. Shrimpton was in the chair for the whole symposium and it was opened by Mr. J. Carver, H.M. Chief Inspector of Mines and Quarries, although there is no record of any address or comments that he may have made. Two of the papers presented at the symposium were printed in the Transactions and one of these was on a subject which had become of increased importance since it was delivered. This was on the subject of “Effluent Treatment” and it was delivered by Dr. M.J. Pemberton. He spoke about about the increased demand for water and hence the importance of reducing the level of pollution in water being returned to the environment as waste. He spoke of the history of attempts to control pollution by Government dating back, incredibly, as far as 1388 with varying degrees of success. In the twenty years before the date of this paper there had been three Acts of Parliament dealing with the subject. The speaker pointed out that there was no universal standard for acceptable levels of pollution because although the World Health Organisation (WHO) had a set of standards, every Water Authority set its own levels. The only thing in common seemed to be that each new set of standards set lower levels than the last. The other paper printed in the Transactions was “A Review of Mine Surveying Practice” by Mr. R.C.A. Hooper. There was no report of any questions or discussion on either of these papers. It is of minor interest that this Symposium was held at the new facilities of the Camborne School of Mines at Trevenson and lunch was taken in the Training Restaurant of the Cornwall Technical College.
Annual General Meeting
The Annual General Meeting was held at the Camborne School of Mines on 28th April 1977, with the President, Mr. G.J. Shrimpton in the Chair. The Council Report and financial statement were presented by Mr. F. Hutchin.
The Council reported that six new Members and and one Student were elected to membership during the year and there were two resignations during the year. The membership was now as follows: 148 Members, 21 Students and 3 Company subscribers. However it is worth noting that this does not correspond exactly with the figures given in the previous year’s report. At the Annual Council meeting on 25th April the following had been elected to the Council following the ballot:- Messrs. F. Hutchin, F.B. Michell, B.O. Rees and T. Andrews and Dr. S.V. Phillips.
Mr. B.O. Rees proposed and Mr. J. Symons seconded that Mr. C.V. Smale the Senior Vice-President should be elected President. This was agreed unanimously.
Mr. A.D. Bennetts was elected as senior Vice-President and Mr. G.C. Pengelly as Junior Vice-President.
Mr. F. Hutchin proposed and Mr. F.B. Michell seconded that Mr. Trevena continue in office as Treasurer. This was agreed unanimously.
Messrs. B.O.Rees and A.D. Bennetts were re-elected as Auditors.
The President paid tribute to Mr. F. Hutchin for his work as Secretary for 37 years and now wished to retire. The President proposed that Mr. G.C. Barratt should be re-elected and said that Mr K.H. Thomson would be willing to act as the other Joint Secretary. These proposals were seconded and and passed.
The Balances brought forward on 1st January 1976 were:- Barclays Bank No 1 a/c £407.65 and Barclays Bank No 2 a/c £192.80. The income was £331.36. Expenditure was £151.86. Total Balances at 31st December 1976 were £779.95.
The Union Trustee Savings Bank Account increased slightly from £391.19 to £417.76
The William Thomas Memorial Fund decreased slightly from £116.59 to £115.64 after allowing for interest and the award of a prize
At the close of the Annual General Meeting six technical films were shown.
As already noted the President’s address was included in this volume of the Transactions along with details of the Institute’s prizes and these are described in chapter ???????
The President elected for the 1977/78 and 1978/79 sessions was Mr. C. V. Smale. The programme for the 1977/78 session consisted of six General Meeting which included a combined meeting with the Minerals Engineering Society and one with Royal Geological Society of Cornwall. In addition there was the Annual General Meeting and the Institute once again organised the Annual Mining and Quarrying Symposium – the fourteenth.
The session started with the Seventh Biennial Dinner at the Regal Hotel, Redruth on 25th May 1977, when Mr. Shrimpton formally handed over the office of President to Mr. C. V. Smale. In addition Mr. Frank Hutchin was presented with a silver salver to mark his retirement after 37 years as Joint Secretary of the Institute.
As well as the dinner a Summer Meeting was held on September 17th 1977 before the start of the General Meetings in October. The meeting was a visit to Messrs. Blake Bearne’s ball clay installation at Newton Abbott. There was only a small turn out but the records do not say exactly how many. This seems to have been a lost opportunity for members since it was a fitting precursor to the President’s address to the first General Meeting on 5th October 1977. Mr. Smale’s address was on “The Cornish China Stone Industry.” The paper summarised the history of the industry from the turn of the 18th and 19th centuries up to the current time (1977). By 1807 there were seven china stone quarries working attached to china clay pits and producing about 1000 tons per year. By 1880 there were 20 quarries producing up to 40,000 tons per year for both home and overseas markets. In 1913 these had increased to 30 quarries and 70,000 tons. The 1914 – 1918 war and the depression that followed reduced demand as did the growth in overseas availability of felspar. During the 1939 – 1945 war this trend continued so that by 1950 there were only 10 quarries working. By the time of this talk there were only three quarries working employing only 30 men producing less than 10,000 tons per year..
The 14th Annual Mining and Quarrying Symposium was held in the lecture theatre of the Camborne School of Mines on 3rd November 1976 and lunch was taken in the Training Restaurant of the Cornwall Technical College. The President Mr. C.V. Smale, was in the chair and the opening speech was delivered byThe Rt. Hon. Viscount Falmouth. Four papers were presented one of which, “The Environmental Impact of Metallurgical Processing Operations” by Mr. I.C. Herbert was printed in the Transactions. This very wide ranging paper occupied twenty A4 pages of print but there is no record of any comments or discussion. The connection between the subject of this paper and the paper on environmental issues presented at the previous year’s Symposium should have made for an interesting discussion. The other three papers were:- “Large Scale Blasting in Quarries” by Mr. A. R. Randle, “The Use of On-Stream Analysis in Mineral Processing” by Mr. E. Crowther and “Safe Man Riding in Mines” by Messrs. W. G. Stephenson and P. J. Tyrrell.
None of the papers presented at the subsequent General Meetings was printed in the Transactions. The second General Meeting was scheduled in the programme for 9th November but reported in the Transactions to have been held at the ECLP Laboratories Lecture Theatre at St Austell on 9th October, only four days after the first General Meeting. Since the third General Meeting was not held until 15th December, it suggests that this may have been a misprint and that the date in the Transactions was in error.
The fifth General Meeting on 15th February 1978, was a joint meeting with the Royal Geological Society of Cornwall to hear a paper on “The Role of the Mining Geologist” by Mr. C.C J. Burton. Before this meeting the President led a short silence in memory of Mr. E.C. Knuckey a former President and a current Member of Council who had recently died.
The unusual subject of the sixth General Meeting on 23rd March 1978, was “The Insurance Surveyor’s Role in Industry and Commerce” delivered by Mr. B. Hartley of the British Engine Insurance Company Limited assisted by his colleague Mr. Paul.
Annual General Meeting
The Annual General Meeting was held at the Camborne School of Mines on 26th April 1978, with the President, Mr. C.V. Smale, in the chair. He asked Mr. A. W. Brooks to present the Secretaries’ report. There is nothing in the Transactions report of the Meeting that can readily be identified as the Secretaries’ report most of information in the Transactions being about the proceedings at the AGM, including the Financial statement.
The Council had passed a resolution to increase subscriptions from £2.00 to £5.00 per annum and this was put to the AGM by Mr. A.J. Human, seconded by Mr. A.D. Bennetts and carried unanimously.
Mr. A.J. Human made two propositions; firstly that the Institute should have a Presidential Chain of Office and he said that he would be prepared to donate towards the cost. Secondly that the Institute should have an official tie. The President said that these topics had been discussed in Council and a decision on putting them to the AGM had been deferred because of the Institute’s poor financial position. Mr. Human asked if he might put his proposals to the next AGM. The President agreed.
The President reported that the current Honorary Secretary, Mr. A. Travena was retiring shortly and that he suggested that Mr. R. J. Pollard should be elected as Joint Honorary Secretary until the date of Mr Travena’s retirement. This was agreed.
He also reported that Mr. G.C. Barret was unable to continue as Joint Secretary. Mr Smale said that a record of thanks should be minuted for his services to the Institute.
It was proposed that Mr. A.W. Brooks who had been acting as Joint Secretary since Mr. Thompson’s departure to Nigeria should be elected. It was also proposed that Mr. C.W.E.H. Smith should be elected as the other Joint Secretary. These proposals were seconded and carried unanimously by the meeting.
Messrs. B.O. Rees and A.D. Bennetts were re-elected as Honorary Auditors.
In the absence of the Honorary Treasurer his report was read by the President. The 1977 Symposium Account had shown an income of £219.00 from the sale of tickets and expenditure of £134.00 leaving a surplus of £85.00.
The General Account had a balance of £779.95 brought forward on 1st January 1997 and the income was £429.37. Expenditure was £998.31 leaving a balance of £211.01 on 31st December 1977. The Trustee Savings Bank Account and the William Thomas Memorial Fund both showed small increases to £445.28 and £119.99 respectively. The balance standing to the credit of the Cornwall Industrial Trust was £3859.54 and there is a holding of £4200 Treasury stock valued at £3664.78 in March 1978.
The Council Report and the Financial Statement were both accepted.
The President closed the meeting and Mr. A.L. Thomas delivered what was described as “ a highly entertaining and masterly lecture” entitled “ A Lifetime in Mining”.
Mr. M.C.V. Smale was President for the second session of his two year period of office and the programme consisted of seven General Meetings, including two combined meetings, with the Minerals Engineering Society, one of them with Royal Geological Society of Cornwall and the other with the Camborne School of Mines. There was also a Summer Meeting, as well as the Annual General Meeting and the Institute once again organised the Annual Mining and Quarrying Symposium – the fifteenth.
For the Summer Meeting, on 9th September, 1978, members and guests assembled at the offices of the Goonvean and Rostowrack China Clay Company before visiting the Goonvean Clay Pit then to the the Trelavour drying plant. This visit was personally conducted by the President. The final visit was to the Wheal Martyn China Clay Museum where they were shown round by the Curator, Mr. John Stenglehoffen and were entertained to tea and pasties to conclude the meeting.
The first General Meeting, held at the Camborne School of Mines on 27th September, with the President in the chair heard a lecture on “Conveying in the Extractive Industries” by Mr. G. L. Meredith of Dowty Meco. He was given a vote of thanks but there is no record of any discussion and the lecture notes were not printed in the Transactions.
This set the pattern for the remaining General Meetings including the three held jointly with other organisations. The meetings covered a wide range of subjects including “The NCB Selby Project” on 8th November while the third General Meeting on 6th December heard a talk on “Subsea Engineering” by Dr. M. G. Haywood, who was a member of the Institute and he gave what was described as an “original” account of the repair of a gas pipeline at the bottom of the North Sea. “Landscape and Reclamation” on 17th January 1979, and “Geothermal Energy” on 21st February, were the subjects of the fourth and fifth General meetings respectively. On 7th March, the Sixth General Meeting, held jointly with the Camborne School of Mines, heard a talk on “The Polish Mining Industry” given by Professor W. Trutwin from the Polish Academy of Sciences. The Transactions mention a discussion, details of which were not recorded. The seventh and final General Meeting was a joint meeting with the Royal Geological Society of Cornwall held on 21st March and it heard a paper entitled “Current Thinking on Granites in South West England and their Associated Mineralisation” presented by Dr. J. H. Hawkes of “The Institute of Geological Sciences.” The Transactions record that there was a spirited discussion but gave no details.
The 15th Annual Mining and Quarrying Symposium was held in the Lecture Theatre at the Camborne School of Mines on 25th October. The President was in the chair for the whole Symposium and he asked Mr. J. F. James, Managing Director of Compair Construction and Mining Limited to give the opening address. There were four other presentations one of which, “The Application of Hydrometallurgical Process Routes for the Recovery of Metals from Low-Grade Deposits – The Development of Hydrometallurgy and its Future Potential”. was printed in the Transactions. This was rather a long title for a relatively short paper which was recorded in less less that nine A4 pages.
Annual General Meeting, 25th April 1979
The President brought the meeting’s attention to the Council’s recommendation that the Associate Membership subscription should be increased to £3.00 and Student Membership remain at £1.00. These proposals were unanimously approved.
Mr. R. Pollard was re-elected as Honorary Treasurer and Messrs. B.O. Rees and F. Hutchin were elected as Honorary Auditors.
The Council reported that at the Annual Council Meeting on 23rd April, the following were elected to Council as a result of the Members’ ballot:- Messrs. J. Brooke, L. J. Bullen, B. Earl, R. Pascoe, G.C. Pengilly, G.J. Shrimpton, H.R. Falcon-Steward and Dr. P. Hackett.
The President, referring to the Minutes of the 1978 AGM, reported that the topics of an Institute Tie and a Chain of Office had been considered by the Council who felt that a lapel badge should be preferable to a tie from the point of view of fashion and cost. He said that the proposal was that there should be a Presidential Chain of Office with a medallion made of Cornish Tin. Both these recommendations had been proposed and seconded by Members and were duly approved.
Dr. C. V. Phillips proposed that Mr. A.D. Bennetts, the Senior Vice-President should be elected as President. This was seconded by Mr. F.B. Michell and carried unanimously.
It was proposed that Mr. G.C. Pengelly should be re-elected as Vice-President and that Mr. R. Pascoe should be elected as the second Vice-President. Both proposals were accepted unanimously. Messrs. A. W. Brooks and C. W. Smith were re-elected as Honorary Secretaries.
In the absence of the Honorary Treasurer the Financial Report was read by Mr. A. W. Brooks. The Symposium Account showed an income of £157.50 from the sale of tickets, an expenditure of £166.50 including unpaid fees of £14.00 resulting in a loss of £9.00
The General Account had a balance brought forward on 1st January 1978, of £211.01 and the income was £722.79. Expenditure was £670.20 leaving a balance of £263.60 on 31st December 1978. The Trustee Savings Bank Account and the William Thomas Memorial fund once again showed small increases to £463.60 and £124.51 respectively.
The Financial report states that there is a balance sheet for the Cornwall Industrial Trust attached but it does not appear in the Transactions. However the Financial report says the balance was £1070.97 which is difficult to equate with the previous year’s statement which showed a balance of £3859.54 plus Treasury stock valued at £3664.78 .
The Secretaries’ Report and the Financial Report were both accepted by the Meeting which was then closed by the President who then invited Mr. J. P. R. Polkinghorne to give his talk on “A Lifetime in the Minerals Industry”, which gave a résumé of his professional career.
