Taylor has resigned his seat on theBoards of Vickers Limited and English Steel Corporation Limited. He retainshis dhectorship of Taylor Bros. & Co., Ltd., which company is a subsidiary ofEnglish Steel Corporation Limited. The Nickel Bulletin 'THE Nickel Bulletin for August con-J- tains an extensive abstract of a paper of American origin on nickel andnickel alloy thermocouples. Further, work, carried out in America, on preci-pitation-hardening of nickel and nickel- iron alloys is also abstracted at length.An important paper recently issued gives data on the types of steel stan-dardised by the Society of Automotive Engineers of America and on their Britishequivalents. Copies of this paper, The Nickel Bulletin, may be obtained, freeof charge, from The Morid Nickel Com- pany, Limited, 2, LTpper Brighton Road,Surbiton, Surrey. Tool Catalogue A THIRTY-EIGHT page catalogue oftheir complete range of pneumatic and electric tools has been issued by theConsolidated Pneumatic Tool Co., Ltd. The different types of tools, all withvariations for specialised purposes, amounts to hundreds. Twelve pages, forinstance, are devoted to various riveting and dimpling machines alone, and in-clude both slow-hitting and fast-hitting types, single-impact types, close-quar-ters types, and a variety of pedestal- mounted tools. The Consolidated Pneumatic Tool Co.,Ltd., will send a copy of this publication upon receipt of a request from interestedconcerns. Applications should be ad- dressed to 232, Dawes Road, London,S.W.6. The Accumulator Manufacturers' Export Group THIS Export Group was formed at theinstance of the Export Council of the Board of Trade on May iGth last, thefirst step being a meeting of all interested parties on that day at the Board ofTrade offices, under the chairmanship of Sir Clive Baillieu. As a result of themeeting a committee was elected, Mr. D. P. Dunne, managing director of TheChloride Electrical Storage Co., Ltd., be- ing unanimously ' appointed chairman,and Mr. Edward Powell the secretary. Almost every' accumulator maker inthe country is a member of the Group, and the following were elected to thecommittee: Mr. D. P. Dunne, chairman ; Mr. F. J. Holmes, Hart Accumulator Co.,JLtd.; Mr. W. H. Denby, The Chloride Electrical Storage Co., Ltd.; Mr. G. B.Page, Accumulators of Woking (1928), Ltd.; Mr. A. H. Shaw, Young Accumula-tor Co., Ltd. ; Mr. Edward Powell, secre- tary. The object of the Export Group is,in the main, to facilitate and expand the accumulator export trade. The Group,represented by the committee, working in close association with the Board ofTrade and B.E.A.M.A., has already taken active steps in this direction, par-ticular attention being paid to securing export business in those neutral countrieswhich, before the war, were strongholds of the enemy, or of countries nowoccupied by the enemy. Apart from the expansion of the exportmarket itself, certain matters relating to the" provision and distribution of rawmaterials, labour, and the like, come within the scope of the Group, as also dosuch subjects as the provision of freight and foreign currency. The offices of the Group are at 27,Bedford Row, London, W.C.i. Tel. No.: Chancery 7221. The Burning QuestionT HE National Fire Protection Co.,Ltd., of Richmond, Surrey, claim for their National D.X. Powder and"494" cooling liquid, the perfect weapon in lighting burning metals, andthis includes, of course, the incendiary bomb of the thermit magnesium type,While the thermit core is burning and supplying its own oxygen there is noknown way of extinguishing the bomb, but in the secondary stage D.X. powderis effective. It is necessary merely to cover thebomb with the powder and roll it over in a small area until it is thoroughly-coated,when the flames will be extinguished. If the bomb is resting on a non-inflam-mable surface simply cover it with more power, but if on a wood floor, for in-stance, the heat may cause re-ignition. It is, therefore, necessary to remove thebomb, which may either be carried to a safe place in the shovel or immersedin the "494" liquid. This is delivered in a container having an oil-tight innerseal and a loose top cover. Its use is not suggested in cases wherelarge retorts have exploded, nor in fac- tory fires where a large store of metal iskept, but a supply should be kept handy where machining and grinding of lightalloys takes place. " Instantair" Approved AIR MINISTRY approval has nowbeen given to the '' Instantair '' Coupling manufactured by B.E.N.Patents, of High Wycombe, Bucks. For some time this device has been largelyused for groundwork in connection with the servicing of aircraft and operation ofpneumatic tools, high-pressure boosters, etc., and it is now in process of stan-dardisation throughout the Royal Air Force. The "Instantair" consists of-aplug and socket, the latter incorporating an automatic non-return valve. Anyitem of compressed air operated equip- ment can be plugged in by a bayonetjoint. The action of disconnecting th,e plug automatically closes the valve andshuts off the compressed air.
