874 FLIGHT International, 21 May 1964 INDUSTRY International Products Company News Great Britain Symposium on Dynamic Balancing The dynamic balancing of rotating machinery is becoming increasingly important as the rotational speeds increase. If the modern requirements of quiet and vibration-free running, coupled with the desire for longer trouble-free life, are to be met, then facili- ties for accurate balancing must be available. W. & T. Avery Ltd, long-established manu- facturers of weighing and testing machines, recently sponsored a symposium at the Department of Mechanical Engineering, Birmingham University, on dynamic bal- ancing, which forms an important part of their business. Among the papers presented was one by Mr K. S. Hodgkinson of Rolls-Royce on Gas Turbine Aero-Engine Rotor Balance and Vibration. Speaking of the Spey engine, he said that the importance paid by his com- pany to the achievement and maintenance of good balance throughout the design, development and tooling stages has paid dividends. The Spey was the first new engine to which Rolls-Royce had applied this close attention, and as a result it has proved to be the smoothest-running axial- compressor engine they have ever made. Copies of this and the other papers pre- sented will shortly be available on request to W. & T. Avery Ltd, Soho Foundry, Birmingham 40. US Alclad for One-Eleven Imperial Aluminium Company, sole British agent for the Aluminium Company of America, has received an order from BAC, Weybridge, for 52 tons of skin quality Alcoa Alclad 2024 sheets. These sheets will be used for skinning One-Eleven short-haul airliners. Alcoa Alclad 2024 sheets are produced with a high lustre, high quality surface suitable for use on the aircraft without painting or further surface treatment. This particular quality of aluminium is not at present available in the UK from other sources. Solartron Founder Joins Fenlow Mr Leslie B. Copestick has joined Mr D. McDonnell and Mr R. L. B. Wall on the board of Fenlow Electronics Ltd, of Weybridge, Surrey, and has been appointed chairman. Mr Copestick was co-founder in 1948 of the Solartron group. After 15 years, during much of which he supervised research and development, Mr Copestick relinquished his interest in Solartron in 1963. Selling Bonded Structures A Dutchman has been appointed sales manager of Bonded Structures Ltd, Duxford, Cambs, an associate company of CIBA (A.R.L.) Ltd. He is Mr D. Ris, who graduated at Haarlem in aircraft technology and joined the company last year from Fokker, where he was engaged in the development and testing of bonding processes and equipment and the design and non-destructive testing of bonded aircraft compoaents. TSR.2 Integral Tank Sealing It is felt that the article on TSR.2 published in our April 9 issue may have given rise to con- fusion with regard to the materials used for sealing the integral fuel tanks of that aircraft. The sealants used both in the original stages of development and at the present time are, in fact, produced by British Paints Ltd at their Newcastle-upon- Tyne factory. The materials are being manufactured under licence from Products Research Co International of Los Angeles. Two series of sealants are used, the PR 1400 type for temperatures up to 130°C and the PR 1700 type for higher temperatures. The PR 1400 series of sealants have been in general use throughout the aircraft industry for several years, and their application to TSR.2 presented no particular problems. The PR 1700 series were new developments and did present formulation and applica- tion difficulties. Co-operation between BAC and British Paints Ltd resulted in materials and application techniques which are currently standard on the aircraft, and at present there is no move to change these standards. It should be clear from the above that British Paints are the sole suppliers for the main sealing compounds used on TSR.2 tanks at the present time. Trident's Sperry Instruments In the caption to the Trident's blind flying "T" which appeared on page 538 of the April 2 issue the Sperry Gyroscope Company's attitude director was erroneously attributed to another manufacturer. For the record, the ASI is also by Sperry. USA New Head For Bendix International Mr L. Edwin Smart, Jr, has been appointed vice-president of international operations of the Bendix Corporation. Mr Smart is also made a member of the corporation's administration committee.

Mr Smart has been closely involved in Bendix legal affairs as a partner in Bendix corporate counsel, Hughes, Hubbard, Blair and Reed, of New York. Mr Smart served in the Second World War with the USN and saw action in the Pacific as captain of a submarine chaser. Born in Columbus, Ohio, he has been with Hughes, Hubbard, Blair and Reed since graduation from Harvard Law School in 1949 and partner in charge of Bendix legal work since 1957.

Westinghouse International Forms Defence and Space Subsidiary Formation of the Westinghouse International Defense and Space Corp has been announced by the Westinghouse Electric Internatienal Co. President of the new corporation is Mr Peter G. Schmitt, who also will continue to serve in his present position of vice-president advanced technology products, for West- inghouse International. The new subsidiary has been formed to serve "as the nucleus for all Westinghouse defence and space activities in Europe and the Far East, and as such it will be in a better position to offer maximum services to customers in those areas." The space corporation will work closely with the Westinghouse defence and space centre at Baltimore, Md, and the aerospace electrical division at Lima, Ohio.

Canada 727 Test Set Garrett Manufacturing Ltd, the Garrett Corporation's Canadian subsidiary at Rexdale, Ont, has developed a portable test set for the Garrett cabin and cockpit temperature control systems m the Boeing 727. Now being delivered to 727 operators, the test set is of less than 1 cu ft volume and weighs just 251b. Simplicity in design enables servicing personnel to learn its operation quickly and the operator is aoie to select individual units within the tem- perature control system and isolate ma- functions. . ., The set is to be adapted to test similar Garrett systems in the Caravelle and xnc DC-9, following the pattern set with in same company's pneumatic signal general . developed to test central air data computer in the F-104 and now used in testing l» pitot-static systems of numerous aircra
