746 FLIGHT, 4 June 1954 THE INDUSTRY Rolls-Royce Apprentice Schemes YOUNG men contemplating a career in the aero-engine indus try will find a great deal of helpful information in two brochures lately published in new editions by Rolls-Royce, Ltd., Derby. One of the two gives details of the six forms of appren ticeship which the company is in a position to offer—trade, tech nical, engineering, laboratory and commercial; the other is devoted entirely to the graduate-apprenticeship scheme. Both publications are very fully illustrated with photographs of Roll- Royce apprentices at work and at play. Intending applicants (who should address their inquiries to the training manager) may wish to know something about the locations of the company's various factories, and for their benefit the brochures contain the following note:— "The Aero Division has its headquarters at the parent factory in Derby, and here is carried on most of the design and develop ment work. There are also factories at Mountsorrel, near Leicester, Barnoldswick in Yorkshire, and a flight development department and airfield at Hucknall. In 1938 the first of the Glasgow group of factories was opened at Hillington and post war expansion led to new factories at East Kilbride, Larkhall and Blantyre. Cars are now made at Crewe, while oil engines are manufactured at a newly built and growing factory at Derby." For Starter-Motor^Testing RECENTLY introduced by the City Electrical Co., Ltd., Emerald Street, London, W.C.I, as an addition to a range of equipment for load and torque tests on electric motors, genera tors, pumps and compressors, is the S210 torque tester. It has been specifically designed to determine torque output of aircraft starter motors used on either piston-engines or gas turbines. For piston-engine starters, which run at comparatively low speeds, the equipment utilizes a pony brake of accepted standard, giving readings on a large scale-dial; for high-speed turbine star ters, a step-down gearbox is inserted between the motor and the brake. A rectifier is included to provide direct current, together with a unit for 24-volt supplies, a carbon pile providing voltage regulation. Similar units are available with series/parallel switch ing to provide 24 to 112 volts output. The main direct-current ammeter and voltmeter, and a clock, are mounted above the rectifier, in a position clearly visible to the operator. Another feature of the apparatus is a bench for tests of high speed motors and turbine starter-motor panels. Its instrument panel carries a main ammeter and voltmeter, clock, coil-current The City Electical motor-test equipment described on this page. ammeter and H.T. alternating current flash-test panel. For tests of starter panels the main contractors are loaded to 500 amp D.C., obtained from the main rectifier and absorbed by the carbon-pile resistors. The supply to the operating coils of the contactor and timing relays is obtained from a small battery which is con tained within the bench and has its own charging rectifier and instruments. For some starter circuits, lamps at the top of the instrument panel act as resistances. A tubular gantry on each side of the bench is provided to carry spring balances when high speed motors are being tested. To Secure Cable-runs FROM Howard Clayton-Wright, Ltd., Wellesbourne, Warwick shire, comes a leaflet describing their new Claytonrite moulded "Nylastic" support clips for cable and piping runs. Available in six sizes, these clips are strong, light in weight (die specific gravity of nylon, of which they are made, is 1.14) and are resistant to the various liquids with which, in aircraft use, they are likely to come into contact. Although there is a certain amount of flexi bility inherent in the plain clip, a sponge-rubber-lined type is also available, as in an earthing clip with a copper lining tongue. In all these clips, fixing is provided for by a hole at one end and a slot at the other, internal serrations being provided to fix the clip diameter positively when the securing bolt is tightened. IN BRIEF Boulton Paul Aircraft net profit for the year ended July 31st, 1953, recently announced, was £226,483 (previous year, £107,744). At a meeting of the Board, it was decided to recommend a dividend of 15 per cent, less income tax at 9s. * * * Recent appointments by Shell-Mex and B.P., Ltd., include that of Mr. R. G. Woodman as aviation manager, southern division. * * * A most useful pocket-size publication by High Duty Alloys, Ltd., Slough, Bucks, is Hiduminium Aluminium Alloys and their Foreign Equivalents. * * * Care and maintenance of K.L.G. aviation plugs (Corundite insulator types) is the subject of a new illustrated brochure— publication No. K.A/1—issued by Smiths Aircraft Instruments, Ltd., who are sole distributors of K.L.G. aviation plugs. * * * Murex Welding Processes, Ltd., Waltham Cross, Herts, have issued matter dealing with their zirconiated tungsten electrodes for use in argon-arc welding. It is stated that these new electrodes have greater resistance to the pure tungsten and thoriated tungsten generally used in this process. * * * Mr. H. Cock, A.C.A., has been appointed secretary to Lodge Plugs, Ltd., Rugby. Leaving Cadbury's in 1948 to join Lodge as accountant, he was promoted to assistant secretary last year. In his new post he succeeds Mr. G. Harrison, who has been with the company for 30 years. * * * Designed to perform the important function of removing corro sive moisture, abrasive scale and other unwanted matter from compressed-air lines, transparent-bowl filters are described in a leaflet from C. A. Norgren, Ltd., Shipston-on-Stour, Warwick shire. Four models are available, for pipe sizes from \ in to 1 in. The British Aluminium Co., Ltd., announces that Mr. George Boex will be retiring from his joint managing directorship on July 4th; he will be succeeded by Mr. W. J. Thomas. Mr. Boex will remain a director and has agreed to carry out any consultant work which the Board may ask him to undertake. • * * As a result of a recent visit to the U.S.A., Mr. Clifford Shaw, a director of Shaw Processes, Ltd., was able to open negotiations for 15 U.S. firms to take out licences for the company's foundry processes. In Canada, Mr. Winnett Boyd, formerly chief designer to A. V. Roe (Canada), Ltd., was formerly appointed to represent Shaw Processes, Ltd. * * * Among the instructional wall charts which are a speciality of the Illustrated Classroom Education Co., Ltd., of 30/31 Hanover Court, Hanover Square, London, W.l, is a 40in x 30in chart explaining the operation of a turbojet. This particular chart is obtainable, price 5s 6d, direct from G, B. Film Division, 1, Aintree Road, Perivale, Middlesex. • * * Representatives from the Imperial Defence College, during a recent tour of northern industrial centres, saw an interesting demonstration of two aircraft tractors at the Meltham, York shire, factory of David Brown Tractors (Engineering), Ltd. The lighter machine, weighing just over two tons, was used to tow the heavier—nearly five tons—up a half-mile gradient of 1 in 6. * * * Trading results of James Booth and Co., Ltd., for 1953, announced at the recent annual general meeting, showed a sur plus of £199,699 after transferring £50,000 from stock reserve to meet losses arising from falls in metal prices. This, added to the opening balance, left £509,141 available for allocation. A 20 per cent dividend on the Ordinary shares was recommended, amount ing to £82,500; £6,160 had been paid on the Preference shares.
