I move:—
That a supplementary sum not exceeding £5,500 be granted to defray the charge which will come in course of payment during the year ending 31st March, 1943, for the Emergency Scientific Research Bureau, including a Grant-in-Aid.
The original Estimate for the current year amounted to £19,000 made up as follows:—Sub-head A: Honoraria to members of the Bureau (£1,500) and incidental expenses (£250), making a total of £1,750; sub-head B: Grant in Aid of Investigation and Research, £17,250; making a total of £19,000. The sum of £5,500 now required for investigation and research brings the total under that sub-head up to £22,750 and the total net Estimate up to £24,500.
In moving this Estimate I outlined the method of work of the bureau and the principal investigations in which it was engaged. Deputies can refer to Vol. 88, No. 2, of the 6 o'clock. Official Debates for 14th to 17th July, 1942, if they wish to look up that part of the report, as I do not propose to repeat it now. I included in my statement a short account of the results which had been obtained, and I indicated the extent to which the bureau had proved to be of assistance to the Government Departments and to industrial firms.
Expenditure in the current year has been incurred mainly on the following: investigations on fuel problems, the production of supplies for refrigeration and water purification, the manufacture of disinfectants, organic, etc., acids, fish oils, sulphur and phosphorus, also investigations relating to geophysical survey, broadcasting, and marine algae, the production of medical supplies, carbon black, carbon electrodes, batteries, fertilisers, and so on, problems arising from shortages of iron and steel and a number of minor investigations; there was also, of course, expenditure on the office work of the bureau. The expenditure required for investigations and researches during the full year is now estimated at £24,622, an increase of £7,372 in the amount originally provided. This increase arises from estimated increases amounting to £10,393 on a number of investigations, offset by decreases amounting to £3,021 in the expenditure originally estimated for a number of other investigations. The gross increase is also offset by a sum of £994, being the unexpended balance of the Grant-in-Aid carried forward from 1941-42, and by income in respect of services or investigations carried out on a repayment basis, which will yield certain receipts estimated at about £900. This results in a net increase of about £5,500.
The gross increase of £10,393 arises from increased expenditure amounting to £6,345 on various aspects of the fuel problem, £247 on investigations into the production of organic acids, £60 on. the production of fish oils and sulphur, £3,235 on miscellaneous investigations and new work, and £506 on office work. The figure of £6,345 on fuel problems arises from an increase amounting to £6,480 in the investigation into the production of turf charcoal, less reductions totalling £135 in the amounts required for investigations on other aspects of the fuel problem. The items included in the sum of £3,235 required for miscellaneous investigations and new work are medical supplies, iron and steel, carbon black, carbon electrodes, batteries, fertilisers, marine algae, as well as a number of other investigations.
Most of the expenditure incurred by the bureau arises from investigations on various aspects of the fuel problem. In the seven months ended 31st October last, about £6,000 has been required for investigations on fuel. Of this latter amount, over £5,000 has been spent on investigations on the production of turf charcoal. This investigation is designed to obtain information on the operation of both small units and large plants.
The expenditure required by the bureau during the current financial year to investigate the production of turf charcoal in large plants is estimated at £10,880. At the time the Estimate was prepared it was expected that expenditure amounting to about £4,400 would suffice for the year. Additional expenditure of £2,000 to meet the cost of a power-house, condensing plant and temporary control laboratory, and of £4,480 in respect of operational expenses is, however, now expected.
When the bureau's plans for the investigation on turf charcoal in large plants were drawn up in July, 1941, it was expected that the power required to operate the plant could be supplied from the existing power station at Turraun. The load, however, required by the new plant is greater than was originally expected, and could not be provided without interference with the production of turf. A new power-station is consequently necessary for the bureau's plant. The condensing plant and temporary control laboratory are required to provide for the recovery of the gaseous by-products of carbonisation. It was not considered necessary when the plant was originally designed to include plant for this purpose. Subsequently, however, increased interest was aroused in the possibilities of tar, wax, and other by-products obtained from peat carbonisation, so that it became desirable to study methods for the recovery and utilisation of these by-products.
The experimental plant at Turraun comprises two full-size retorts, one of steel and the other of firebrick. The erection of these retorts has been completed, and considerable progress has been made in the construction of the power house, condensing plant and control laboratory. Heating of the producers and retorts has been in progress for some weeks, and it is expected that production of charcoal will commence in the near future.
In carrying out this investigation the bureau has not lost sight of the fact that it may not be possible to set up large plants under existing conditions to produce charcoal on the scale required. In the course of its work the bureau takes every opportunity presented to it to study methods proposed for the production of turf charcoal, and the lines of investigation which are now being followed by experimental work are those which appear most likely to meet the national need. The investigation on production in small units has included experimental work both in steel kilns and in pits dug in the ground. Promising results have been obtained, and it is hoped to conduct further experiments on a number of bogs throughout the country.
The most important of the other matters included in the fuel investigations are a study of the most suitable types of gas producer for use with available fuels, and the investigation of emergency difficulties in the manufacture of town gas. The work on producers has included work both in the laboratory and on the road into improvements of the filtration system, as well as a study of the most suitable fuels for use in tuyere and grate types of producer. Work on this problem has enabled the bureau to collaborate in a number of investigations being conducted by various commercial concerns. The bureau's recent work on town gas has been principally devoted to assisting in an examination of the problems relating to the use of turf. It is hoped to commence shortly to investigate the production of water gas from peat. Arrangements are also being made to commence an investigation on the catalytic enrichment of turf gas. This might also be important in connection with the possible development, after the emergency, of the production on the bog of gas from turf on the large scale.
The bureau's investigations into the production of various organic acids have now been discontinued, as it is expected that an industrial firm will set up plants for the production of citric acid and lactic acid. However, the preliminary work carried out during the year has resulted in greater expenditure than was expected.
For a considerable time the bureau has devoted attention to the provision of essential medical supplies. Experimental work has been carried out in collaboration with industrial firms which has resulted in the development of methods for the production of glycerine from concentrated soap lyes. The product so far obtained is suitable for use in the preparation of many medicaments, since it is of pharmaceutical quality in all respects except colour. An examination has been made into the building up of a reserve stock of solid, insulin, and methods of dissolving this substance have been studied. Experimental work has been carried out in connection with the standardisation of Irish grown digitalis.
Investigations under the head of iron and steel include an examination of the possibilities of relieving shortages of special alloy steels by the remanufacture of scrap, experiments on the production of iron by electro-deposition, investigations on the use of substitute fuels for melting iron, and the production of ferro-silicon for foundries. Following satisfactory laboratory experiments, the production of electrolytic iron on the large scale is now being studied with specially adapted plant and equipment. It is hoped that production on this plant will commence in the near future. Satisfactory results have been obtained from experiments on the melting of iron with hard turf charcoal made by high temperature carbonisation in gas works retorts.
In connection with the work on the production of carbon black, an experimental plant has been erected and trial runs made. Further experiments will be necessary before any conclusion can be reached as to the probable outcome of this investigation.
During the year an investigation was commenced into the possibilities of producing carbon electrodes suitable for use in electric furnaces. Preliminary experiments carried out in gas works were sufficiently encouraging to justify further work in collaboration with an industrial firm. A special furnace has been erected, and electrodes suitable for use in the manufacture of calcium carbide have been produced on a technical scale.
An investigation is in progress with a view to arrangements being made for the repair and manufacture of lead batteries in the country. A study has been made of the treatment of wood for the production of the separators, and experimental work has been carried out in a specially constructed furnace on the preparation of the lead oxides required. Preliminary work is also being conducted into the possibility of recovering zinc from used dry cells.
It was decided during the year that the bureau should investigate the production of improved fertilisers from indigenous deposits, and experimental work is now in progress.
The investigation on marine algae is mainly confined to collecting information on the occurrence on the western coast of Gelidium and related seaweeds with a view to providing material for use in the preparation of agar-agar. This work is a continuation of certain aspects of research on seaweed which has been in progress under the auspices of the Industrial Research Council. Useful results are being obtained, and one manufacturer has commenced the production of agar by means of a process developed as a result of work carried out under the auspices of the Industrial Research Council.
