648 FLIGHT, 21 October l%0 THE INDUSTRY Tiltman Langley Progress ORIGINALLY Tiltman Langley Laboratories, the firm of Tilt-man Langley Ltd was established in 1947 to undertake research work into the basic strengths of materials for RAEFarnborough. The results of this work are embodied in Design Requirements for Aircraft for the Royal Air Force and RoyalNavy, AP.970, and so have been used in the structural stressing of all British military and commercial aircraft. Meanwhile, Tiltman Langley have greatly expanded theirresearch and test facilities. ARB approval has been granted to cover the test house for the physical testing of ferrous and non-ferrous material, and the company also holds AID Test House Pt 3 approval for the examination of welded, spot-welded, and brazedjoints. A 20,000tt> Macklow-Smith tension-compression machine(approved by Lloyd's Register of Shipping) is currently employed, together with an NPL-type axial fatigue machine, on research forthe MoA into the strengths of joints. Other equipment includes a machine of the company's own design for determining torsionalshear-strengths of tubes and bars; Vickers Hardness and Izod machines; optical extensometers; high-precision gauges; balances;a metallurgical camera-microscope; and a dark-room. Furnaces and baths for the heat treatment of ferrous and non-ferrousmaterials are also in use. Testing can be done over a wide range of temperatures on the tension-compression, fatigue and Izodmachines. All such work is under the supervision of the director of research, Mr E. F. Maillard, BSC (Hons), AFRAes, and is aparticular interest of the technical director, Mr Marcus Langley, MiMechE, FRAes. Research consultant on all metallurgical andmaterial problems is Dr H. Sutton, CBE, DSC, FIM, until recently Director, Materials Research and Development, Ministry ofSupply. Other work by the company has included the fatigue testingof springs and joints, wear of piston rings and cylinders, strain- gauging, and the design and manufacture of test rigs for complexmechanisms and drives. The examination and testing of com- pressed-gas cylinders is also undertaken.The central position of the test house—three miles from Redhill, Surrey—is particularly convenient to the industrial areas of South-east England. Earlier this month the Good- year Tyre & Rubber Co re- vealed the "Thermal" tyre, developed for the Bristol 188. It is claimed that by the em- ployment of certain special techniques, involving "new formulations in compounding and developing materials used in the carcase and tread," the new tyre has roughly double the heat range of conventional tyres and permits the elimina- tion of wheel-bay refrigeration Low-temperature Refrigeration A NEW, large-capacity Philips industrial refrigerating unit has•**• been announced. Based on the same makers' single-cylinder unit, it is intended for more general applications, being describedas "suitable for direct condensation in distillation processes, liquid and gas-stream cooling, and for allied industrial operations callingfor refrigeration in the temperature range down to ~200°C and at a pressure range up to 4501b/sq in." Further characteristicsclaimed for the unit are compactness, and reliability in operation. A special auxiliary unit is also available for the production ofliquid air from the atmosphere; and a fractionating column, to produce liquid nitrogen, is under development. Like the existingPhilips models, both these units operate without the use of pumps or chemicals, suction created by condensation being utilized todraw in the air supply. Moisture, carbon dioxide and other impurities are removed by a freeze-drying technique. Distribution in the UK is by Research & Control InstrumentsLtd, Instrument House, 207 King's Cross Road, London WC1, who also offer an advisory service. IN BRIEF The London office of English Electric Aviation's Aircraft Divisionhas moved from Marconi House to 100 Pall Mall, SW1 (telephone Whitehall 1020). The office is under the control of Air Cdre StrangGraham, commercial director. Hadfields Ltd, of Sheffield, recently appointed two further localdirectors: Mr Denis R. Ward, FCA, the company's assistant secretary, and Mr Arthur W. Gurney, ACWA, chief cost accountant. Mr A. J. Shirley, chief draughtsman of the M.L. Aviation Co Ltd, has been appointed to the board. He joined the original design group of M.L. Aviation in 1941. The Plessey Co Ltd have entered into the final stages of negotiationsto take over the 66-acre former RAF balloon barrage station at Titch- field, on the A27 London - Southampton road. The company is toestablish a new production centre there. Recent staff appointments at Atton Developments (Woking) Ltd arethose of Mr R. T. Pretty—formerly with Vickers-Armstrongs (Aircraft) Ltd—as manager; of Mr T. M. Tamblyn-Watts as senior visualizer andtypographer; and of Mr A. R. C. Holland as senior technical author. Like Mr Pretty, "Dutch" Holland comes from Vickers and has had34 years' experience as a pilot. The company, whose head offices are at 49/50 Maybury Road, Woking, Surrey, are specialists in the preparationof technical publications and publicity. Mr J. C. Reed, formerly sales engineer of Birmingham AluminiumCasting (1903) Co Ltd, the light-alloy founders of Smethwick, Staffs, has been appointed sales manager. Mr R. E. Ford has been appointed divisional manager of the newlycreated Airborne Radio and Radar Division of Elliott Bros (London) Ltd, a member of the Elliott-Automation Group. Mr P. T. Griffith, AFRAes, AMIME, has been appointed aviation consul-tant to the Caltex (UK) Co Ltd. Formerly with BOAC as purchasing controller, Mr Griffith is managing director of the Babb Co (Britain) Ltd. Valay Industries Ltd, makers of the Jove Aero Products range ofaircraft cleaning and polishing materials, have moved to new premises. Their address is now Davis Road, Chessington, Surrey (tel LowerHook 2166; telegrams and cables: Valaypro, Chessington). Mr George Orloff, MiMechE, AFRAes, has joined the Industrial Divi-sion of the Sperry Gyroscope Co Ltd as a consultant. A member of the Society of Instrument Technology, he is well known for his work inconnection with the introduction of 4,0001b/sq in hydraulic systems for a number of aircraft types and also for his developments of flapper spoolservo valves. Electrolube Ltd, Oxford Avenue, Trading Estate, Slough, Bucks,are making their electrical-contact lubricant available in pocket-type dispensers of fountain-pen size. Two varieties are available, one forcleaning and lubricating non-arcing contacts and mechanisms and the Other for lubricating cleaned arcing contacts. The dispenser gives eithera drop or a stream of the lubricant at will. As part of a general reorganization of the sales staff, James BoothAlumium Ltd (Argyle Street Works, Birmingham) have appointed Mr Arthur W. Williams, BSC, AIM, chief technical representative in chargeof their technical sales service department. Mr Williams, who joined the former James Booth & Co Ltd in 1939, was appointed chief inspectorin 1955 and for the last two years has been personal assistant to the works director. Pye Ltd, Honeywell-Brown, Metrovick, DH Propellers, SE Laboratories and New Electronic Products are among the companies which installed instrumentation at the Rocket Propulsion Establishment, Spadeadam (described in our September 16 issue).
