FLIGHT, 2 April 1954 411 THE INDUSTRY Redhill Activities C? PEAKING at the recent annual general meeting of Tiltman ** Langley Laboratories, Ltd., of Redhill, Surrey, the chairman, Mr. A. Hessell Tiltman, reported a tenfold imcreasa of work in hand. He said that the company had received a £200,000 M.o.S. contract for the large-scale production of secret equipment of "the highest national importance" designed and developed by the laboratories. This contract would allow the company to increase its production facilities. Tiltman Langley, it is learned, are at present using a litho graphic process to prepare detail plates for lofting for leading aircraft firms. Mr. Tiltman was responsible for the preparation of die first complete survey of full-scale layout in this country, which he carried out in 1943 for the S.B.A.C. after visiting America widi the Fedden Mission. A sub-committee of the S.B.A.C., of which Mr. Marcus Langley (T. L. managing director) was a member, considered his report and proposed a standardized lay out system for the whole British aircraft industry. In addition to Tiltman Langley's expansion in London, the test houses and workshops at Redhill are also being enlarged. Last year, the company was engaged on a number of Government and commercial contracts, and these included the development of a pesticidal smoke generator (described recendy in Flight). The company also developed a rapid linear actuator test rig, to check die functioning of electrically operated linear actuators from 50 to 1,200 lb line load widi respect to current consumed and operation time when loaded to maker's specifications. In the field of research-equipment development, the company perfected a vibration test-table for the R.A.E. Using a new principle, this unit is capable of giving 20 to 250 c.p.s. frequency, widi accelerations from 0 to 10 g, both infinitely variable inde- pendendy of each other, and operation can be effected wimout stopping the machine. The programme of investigation of the application of the Gerritsen infinitely variable system of transmission and die Hayes gear is continuing at Redhill. Work on die Tiltman Langley flow-valve is also progressing. The Redhill workshops, too, are undertaking a steady volume of modification for various B.O.A.C. and B.E.A. aircraft. Instrument-manufacture Appointment TT is announced that Mr. A. G. Peacock, B.Sc, A.R.I.C., -*- A.Inst.P., has resigned his position as secretary of the Scientific Instrument Manufacturers' Association and has joined the Board of Mervyn Instruments, St. John's, Woking, Surrey. Mr. Peacock is perhaps best known as the hon. exhibition secretary of die Physical Society, and as an advocate of increased publicity for British instruments he is a well-known figure at exhibitions both in this country and abroad. He has been closely concerned widi the activities of the Scientific Instrument Manu facturers' Association, and has for a number of years assisted in the organization of die Electronics Symposium held by the Electrical and Electronics Group of S.I.M.A. Mervyn Instruments, established some 21 years ago, have since 1939 become increasingly active in die commercial instrument field. They also undertake much experimental work on behalf of Government and Service departments. AT THE MARCONI CONFERENCE: Among those who met at Chelmsford to discuss aeronautical radio (see item below) were, left to right: Back row: H. A. Rice, manager, general products divn., C.M.C.; D. Craig, London manager, A.W. A.);A. J. Campbell, i/c production engineering and development, A. W. A.); £. W. Beasley, aviation department, C. M. C. Second row: G. At. Wright, engineer-in- chief, M.W.T.: f. N. Sutherland, general manager, M.W.T.; W. R. Thomas, general management, A.W.(A.); C. E. Tremblay, aviation department manager, C.M.C. Extreme left: Dr. B. J. O'Kane, M.W.T. aeronautical division chief engineer. Extreme right: L. A. Sweny, M.W.T. aeronautical division manager. Aeronautical Radio Discussed "17ALUABLE discussions on the design and use of aeronautical • and navigational radio equipment on a world-wide basis took place at Chelmsford recently, when executives of Marconi's Wireless Telegraph Co., Ltd., and of their overseas associates, Amalgamated Wireless (Australasia), Ltd., and the Canadian Marconi Co., met for a 19-day conference. The chairman was Mr. F. N. Sutherland, manager of the aeronautical division. In his speech of welcome to die delegates, Mr. F. N. Sutherland (Marconi general manager) spoke of the increasing complexity of aeronautical radio requirements, and of the importance of radiocommunications in aiding die safety and reliability of air transport. The problems thus posed, he said, would fully occupy the attention of the visitors. The conference gave the subject of servicing and maintenance facilities particularly careful study; die contribution made by die A.W.(A.) delegation to tiiis item of die agenda was of especial value in view of tiieir long and extensive experience in this specialist field. Among otiier tilings, it was agreed that one essential was a greater degree of standardization in such matters as design practice, components and documentation. In this light the major products of the companies were discussed in detail. Hobson Progress IN his speech at die recent annual general meeting of H. M. Hobson, Ltd., Mr. S. W. Hughes (chairman) said that the company looked forward widi confidence to die future: although the demand for their products for piston engines was affected by die adoption of die jet engine, they still retained a goodly volume of business in bodi new carburettors and spares for aircraft engines. Their new products in die aircraft world, and in die field of guided weapons, had created very great interest, and sub stantial orders had already been placed. The balance sheet of H. M. Hobson, Ltd., and their associated company, Integral, Ltd., was described by Mr. Hughes as being one "of exceptional financial strengdi." As already recorded in Flight, group profit for die year was £380,054, of which taxation absorbs £250,200. For Time-recording IN certain research and development processes, and in other industrial applications—e.g., time-and-motion study—where accurate measurement of time is essential, there is often a need for a high-precision time-interval meter. Such an instrument is marketed by Camerer Cuss and Co., the well known clock and watch specialists of New Oxford Street, London, W.l. It has been developed in conjunction with Allied Electronics, Ltd., of 28 Upper Richmond Road, London, S.W.15. As the power is provided by two standard deaf-aid dry batteries, the instrument is independent of mains and free from any errors introduced by mains frequency. The utility of a stop-watch, and the accuracy of its recording, are greatly increased by using it in con junction with the electrical system described here. Starting and stopping are controlled by die closing of an electric circuit, so that times can be recorded automatically by means of a standard N.P.L.-quality stop-watch incorporated in die instru ment, such as the Camerer Cuss Model 308. Control may be effected over very long circuits, and resetting may also be remotely controlled. Photo-cell units can be introduced.
