156 FLIGHT THE INDUSTRY Rolls-Royce Re-organization CONTINUOUS expansion of foreign business has caused ^ Rolls-Royce, Ltd., to re-organize and strengthen its aircraft- engine sales side. As announced in our pages last August, Air Marshal Sir Colin W. Weedon, K.B.E., C.B., has joined the company; as export sales manager, he now assumes control of all business coming under the heading of export sales promotion and market research. On his staff at Derby he will have G/C. L. R. Stokes, D.F.C., S/L. J. E. Brown, D.F.C., and S/L. F. M. G. Scotter, D.F.C. Sir Colin's department will also be responsible for appointing overseas agents. Now coming under its control are the agencies for Australasia (Mr. Peter Birch, Melbourne), the Benelux countries (Mr. H. Millward, Amsterdam) and North America (A. Cdre. E. R. Pearce, stationed at Rolls-Royce of Canada, Ltd.). The technical sales and services group, with Mr. F. T. Hinkley as its general manager, will control the following departments :— Aero Service (Mr. W. P. Calvert).—Responsible for the servicing of Rolls-Royce aircraft engines throughout the world. Technical Services (Air. D. J. Kay, taking over from Mr. A. Harvey-Bailey, who is shortly to become manager of a new Rolls-Royce repair base in Australia).—Deals with all technical aspects of servicing, such as repair engineering, failure investigation and spares assessment. Commercial Contracts.—Remains under the management of Mr. D. S. Burns, with Mr. E. J. Towlson as his deputy. Licence Office.—Comes under Mr. J. P. Herriot as engineer-in-charg e. The technical services sections in the Glasgow factories are also part of the technical sales and services group. The chief technical executive of the group will be Mr. C. R. Creighton, who will be known as chief technical services engineer. Painting Aluminium IN 1947 the Aluminium Development Association published a booklet (No. 13) on the surface finishing of light alloys. Such progress has been made since that date in the painting of aluminium surfaces that a further booklet (No. 20) has now been published, referring only to this branch of the subject. Information is given on various methods of cleaning and degreasing, followed by details of the pre-treatment required to give a satisfactory surface for paint reception. Methods include chromate and phosphoric-acid baths, swabbing of larger surfaces, and the use of a new "etch" primer, which is a vinyl resin base containing zinc tetroxychromate or chromate. Finally, the possible choice of paint systems is outlined : single-coatings are claimed satisfactory for decorative and general protective purposes, but as many as three or four, including a primer, may be required for surfaces that have to withstand attack from the weather or severe industrial conditions. It is stated that paint-surface lasts unusually well on properly prepared aluminium, and that corrosion does not spread appreciably around an injury. Repainting is also discussed. The booklet may be obtained from A.D.A. at 33 Grosvenor Street, London, W.i. IN B AFTER more than 50 years in their premises at Victoria Street, ' London, the British Standards Institution is to move into new offices at 2 Park Street, W.i, at the end of the summer. * * * The new address of Kenton Equipment, Ltd., world distributors of "B.O.A.C. hydrostatic weighing units" is 708 Kenton Road, Kenton, Harrow, Middlesex (Wordsworth 7805). * * * Three leaflets (FD5, FD10 and FD14) produced by the Morgan Crucible Co., Ltd., of Battersea Church Road, London, S.W.11, give details of their lift-out, tilting and bale-out crucible furnaces. * * * Production of British gas turbines under licence to American manufacturers is bringing the firm of Joseph Lucas, Ltd., £100,000 a year in royalties on patented components. This was disclosed by Mr. A. B. Waring, chairman of the company, in a recent speech made as president of the Birmingham Chamber of Commerce. * * * The first of a series of ten weekly lectures on gas-turbine technology was delivered on January 21st at the South-East London Technical College by Mr. R. C. Orford, M.Sc, C.P.A., A.M.I.E.E., patents manager of Power Jets (Research and Development), Ltd. Subjects covered in the series include a his torical survey, types of open and closed cycles and compound JURILEE CELEBRATION: Caught by the camera at the H. M. Hobson "50-year" dinner at Wolverhampton : Mr. E. A. H. de Poorter (left), who was one of the original three partners in the firm, and Mr. S. A. Davis, Regional Controller, M.o.S. A report on the dinner appeared in our pages last week. Silicone Rubber AN informative booklet recently produced by the Dunlop k Rubber Co., Ltd., explains the properties and limitations of silicone rubber. Natural and synthetic rubbers are essentially hydrocarbons—substances in which the molecules are composed of long chains of carbon atoms. The chains in silicone rubber are made up of alternate silicon and oxygen atoms, and the energy required to break a bond between two such atoms is greater than that required to disrupt a carbon-carbon bond. From these facts arise the surprising and useful properties of the product. Different grades of material can be made by varia tions in the manufacturing process, but the outstanding character istic of them all is the retention of strength, shape and elasticity over a very wide range of temperatures. Thus an ordinary rubber loses most of its flexibility if subjected to a temperature of 300 deg F even for as short a period as 24 hours, while at the other end of the scale it becomes brittle at temperatures of the order of —25 deg F. It is stated that silicone rubbers are available which will satisfactorily withstand prolonged exposure to tempera tures ranging from 350 deg F to —130 deg F, and can undergo occasional heating to 500 deg F without harm. The properties of these materials may not necessarily be better than those of natural rubber at room temperature—frequently they are not; the point is that they retain their properties largely unimpaired under conditions which would cause rapid deteriora tion of natural rubber. Silicone rubbers have good electrical insulating properties, are chemically resistant to hot oil, and withstand the ageing action of water, ultra-violet light and oxydiz- ing agents unusually well. A limited supply of the booklets is available, and executives may obtain copies on application to Dunlop's General Rubber Goods Division, Cambridge Street, Manchester. RIEF cycles, intercooling, reheat, industrial and surface-transport appli cations, and a review of the design and manufacture of components. * * * r On January 20th, A. V-M. H. N. Thornton, C.B.E., sales director of Blackburn and General Aircraft, Ltd., sailed for India on the first leg of a tour which is to cover India, Thailand, Australia and Japan. The purpose of the tour is to expedite overseas sales of the Universal Freighter and Cirrus and Turbomeca engines. * * * Four Froude dynamometers have been dispatched to A. V. Roe (Canada), Ltd., by Heenan and Froude, Ltd., of Worcester, for use in gas-turbine testing. The machines are capable of running at relatively high powers and speeds, thus facilitating the testing of accessory drives, and their hydraulic weighing gear enables power readings to be taken inside a soundproof control cabin situated some distance from the test-bed. * * * The directors of Metalas'tik, Ltd., announce that a long-term manufacturing agreement has been concluded with a leading French concern to produce products under that trade mark for France and the French territories. This agreement provides for close technical and commercial collaboration between the com panies, and orders are being placed in this country for the special- purpose equipment required.
