JUNE 24, 1937. FLIGHT. 655 aluminium alloy sand and die castings in heat-treated and normal alloys for aero engine and aircraft components and small fittings; Elektron magnesium alloy castings, heat- treated and normal (the company's range of castings in aluminium and Elektron alloys includes crankcases, cylinder heads, volutes, covers, pipes, tappet guides, diffusers, tail- . wheel forks, heater valves, hand wheels, cable clamps, pedals, etc.); examples of wrought construction in high-tensile alumi nium alloy sheet and sections, including a leg bracket for fairing and a sliding door; and an exhibit of Birmabright alloy, resis tant to corrosion, for cast and wrought pur poses. This last will include typical ex amples of the alloy as applicable to the con struction of engines and airframes in various finishes, including approved anodic finish. Makers: Birmingham Aluminium Castings (1903) Co., Ltd., Smethwick, Birmingham. JAS. BOOTH (Stand 78).—The display of James Booth and Co. will comprise an ex tensive range of wrought non-ferrous alloy products. Among these the alloy Duralu min is so well known that it will hardly need description. The aluminium-coated form of this material possesses an exceptional resist ance to corrosion. Among the more recent magnesium aluminium alloys are MG7 and D.2. Both possess a very high resistance to corrosion by sea water, the former having a strength almost equal to that of Duralu min. Since D.2 possesses considerable duc tility it is specially suitable for the produc tion of deep pressings or sheet metal work generally. Elektron, which is 40 per cent, lighter than aluminium will be shown promi nently in its various forms. A specially interesting exhibit will be the range of c.p. airscrew blade hot pressings, both in Duralu min and Elektron. There will also be shown a variety of forms of the brass and copper productions of the company. Makers: James Booth and Co. (1915), Ltd., Nechells, Birmingham, 7. ENGLISH STEEL CORPORATION (Stand 62) will make an attractive display of small tools, files, hacksaws and tool steels in specially designed cabinets. Finished drop-forged crankshafts, hubs and flanges, and other aircraft components and precision- ground bar (round and hexagon) will also be shown. Three large photographs, specially coloured and illuminated, will give an excel lent idea of the heavy steel products made at Yickers Works, Sheffield. These will illustrate the melting department, heavy forge and machine shops, which can deal with ingots up to 250 tons in weight, and forgings up to 160 tons. Makers: English Steel Corporation, Ltd., Vickers Works, Sheffield. THOS. FIRTH (Stand 12).—A range of the well-known alloy steels supplied by this company to the leading aircraft companies will be on view on this stand. These will take the form of ground steel bars, illus trated by examples, showing the careful inspection which is carried out through all manufacturing processes, a range of engi neers' small tools, including those supplied for airscrew manufacture, " Speedicut " blades, easy slow spiral drills for high-tensile sheet, Nitralloy sheets for templates in Jin- gauge, milling cutters, " Diehard" and " Millenicut " files, " Speedicut " high-speed steel, airscrew hub stampings and a number of engines and parts, as supplied by the leading aircraft manufacturers, made from Thos. Firth steel. Makers: Thos. Firth and John Brown, Limited, Atlas and Norfolk Works, Sheffield. FIRTH-VICKERS STAINLESS STEELS (Stand 7) will display the various forms in which non-corrodible steels are supplied for aircraft construction. The steel products of the company- may be divided roughly into three groups: the " Staybrite" group (8 per cent, nickel, 18 per cent, chromium); the 2 per cent, nickel, 20 per cent, chromium (S.80) group, and the 12 per cent, chromium steel group. A special exhibit, taking the form of a display board, clearly shows how sheets, strips, bars, drop stampings, tubes and wire of different tensile strengths and belyiging to the different families of steels are mter-related as regards chemical ana ys s and mechanical properties r nifT\fFilth-Vicke,s Stainless Steels, Lnmted Staybnte Works, Sheffield, 9. olav w,i, FLATHER (S^ 5)-Tht dis play will comprise a set of micro-photo graphs showing steel in various fonns, to gether with a full set of release notes show ing typical tests obtained.

Turton, Platts, Ltd and Smith Clayton Forge, Ltd., with whom Samuel Fox work in close co-operation in the supply of aero engine and aircraft parts. Centreless ground bars of iin. to 21m dia meter will also be among the items shown. For purposes where the requirements of the user are particularly stringent attention is drawn to the " Diamet" code of inspec tion, designed to ensure the highest possible standard of cleanness and regularity in the electric steels made by the company. Makers: Samuel Fox and Co., Ltd., Stocksbridge Works, near Sheffield. HABERSHON (Stand 3) will be showing samples of stainless and alloy steels in sheet and strip form, which they manufacture to most of the Air Ministry specifications. In addition, they will display a board on which will be a number of the sections made up from their steel as used in the construction of very many of the modern aeroplanes to day. J. J. Habershon and Sons, Ltd., Rother- ham, Yorks. HIGH DUTY ALLOYS (Stand 42) are manufacturers of the " Hiduminium R.R." series of high-tensile aluminium alloys, and will show a comprehensive range of cast ings, forgings and stampings in their mate rials. Heads, barrels, pistons, blocks, con necting rods, crankcases, supercharger rotors, etc., are shown as typical of the many ap plications of "Hiduminium " alloys to the engines of such firms as Armstrong Siddeley, Bristol, Cirrus, De Havilland, Napier, Pob- joy, Rolls-Koyce, and many of the Contin ental manufacturers. Also exhibited are ex amples of a stamping and a finished blade for the De Havilland c.p. airscrew.

Stone and Co., Ltd., Def>tford, Loudon, S.E.14. Tools, Plant, and Works Equipment AYERY (Stand 25).—A machine of parti cular interest will be the Avery-Browns-don wear tester, which enables wear prob lems to be approached directly by the measurement of wear instead of indirectly by the measurement of friction. The method of operation consists of bringing a flat sta tionary sample of one metal into frictional contact with the periphery of a rotating wheel of another metal under known condi tions of speed and dimensions of the wheel, load, temperature, lubricant and duration of test. The impression so made in the flat sample of metal is then taken as a measure ment of wear, much in the same way as the impression of a ball or cone penetrator is taken as a measurement of hardness. An other Avery machine to be exhibited has been specially designed for determining thi Rockwell hardness of materials during pro duction. A direct numeral reading is glvsa. The balance of airscrews is accurately deter mined by a third machine to be exbi'jittd on this stand. Also exhibited will be a balancing machine for engine connecting rods. This consists of two steelyards which are balanced off with a Standard connecting rod until zero is shown by the two auto-
