804 FLIGHT International, 15 November l%y INDUSTRY International... 120ft in range, for which band-width and a fast pulse-rise time are necessary. The standard AVQ-70 receiver can be modified to incorporate this feature. The unit de monstrated was subsequently due to be evaluated by Air France, Sabena, BOAC and other airlines. The two new weather radars supersede the AVQ-10 and AVQ-50 of which respec tively 2,500 and 500 have been sold to date. Mainly they are transistorized, cost aoout 20 per cent less and have better performance, and they have been designed for simplicity and flexibility of installation. Both the AVQ-20 and AVQ-55 operate unpressurized and the electronics can be installed next to the aerial, avoiding waveguide runs through pressure bulkheads. There are only three cables, for interconnection, stabilization and power; and the last-named can be introduced in any of the three boxes. Aerials of 12in, 15in, 18in or 24in diameter are offered, all having single-axis movement with fewer rotating joints and no slip-rings and no control box. In power, space and waveguide requirements the -20 and -55 are interchangeable and both employ a full-size 5in indicator tube on which all controls are located. Dual transmitter/ receivers or indicators can be provided in any combination. The -55 needs no a.c. power supply. Reliability is improved by fixed-coil display, solid-state switching in all but the timing relay and the use of only eight valves, three of them Nuvistors. There are 73 transistors. Ku Marshal Sir Herbert Spreckley, military adviser to Smiths Aviation Division (see below) Smiths' Military Adviser Air Marshal Sir Herbert D. Spreckley, KBE, CB, FRAes, MiMechE, RAF (Ret), has been appointed military adviser to Smiths Aviation Division and will be concerned with all matters relevant to Service aviation at home and abroad. He will be based at the division's headquarters at Kelvin House, Wembley. Sir Herbert retired from the Royal Air Force in February this year, his last appointment being that of Controller of Engineering and Equipment at the Air Ministry. Prior to that he was AOC No 24 Group, Technical Training Command. Boeing Transfer Mr Kenneth J. Luplow, who for the past six years has been respons ible for Boeing jet transport sales in Europe, is returning to the United States to become director of international sales for the trans port division of the Boeing company. He The -20 is X-band, mainly because of the low cost, small size and availability of components, although R.C.A. pioneered C-band in the -10 and many operators still prefer it. The AVQ-10 weighs 1101b, but the -20 weighs only 451b. Range settings are 30, 90 and 180 miles instead of 20, 50 and 150 miles; and the AVQ-55 offers 30, 60 and 90 miles. Although the AVQ- 10 costs $11,000 after being in production for several years, the new AVQ-20 costs only $8,600. The AVQ-55 costs S6,400. R.C.A. have for some time been working to produce a daylight viewing tube for their weather radar and, after considerable troubles with such a tube for the AVQ-10, have now achieved a mean time between failure of 600hr. A better tube is being prepared for the AVQ-20 and will be supplied free within six months to any customer stating the requirement when purchasing the conventional AVQ-20. The tube operates on the same principles as the English Electric E 702 storage tube used by Marconi in an experimental display at Gatwick airport (see these columns for September 20). A wire mesh screen behind the tube face is covered by a flood gun and scanned by a writing gun. The writing beam changes the polarity of the appro priate portion of the screen and allows signals to pass through to the tube face, where they are held for as long as required. The R.C.A. AVQ-20 has probably been developed in part to meet the compe tition of the Ekco E.190 lightweight weather radar now being produced in the USA by Wilcox. will be responsible for all commercial sales activities outside North America, including Boeing offices in Switzerland and Australia. Mr Luplow, who has been with Boeing for 21 years, has been actively concerned with international operations since 1946, when he established the company's first office in Europe. He is being succeeded in Geneva by Mr Hans Ott, assistant director of the transport division's European office since 1956. Microcell-Palmer Merger BTR Industries Ltd have announced the integration of two of their subsidiary companies, Microcell Ltd and Palmer Aero Products Ltd, which will now form the group's Engineering Products Division. Mr C. G. Erlam is to be chairman and general manager of the new organization; Mr J. A. Grace com mercial manager; Mr P. L. Watson pro duction manager; Mr J. J. Molins technical manager and Mr J. A. Hemingway finance and administration manager. The Kingsway, London, offices of Micro- cell will be vacated and the administrative and design functions transferred to Cam- berley, Surrey, being combined there with similar functions transferred from the Palmer premises at Penfold Street, London NW8, to form a central administration and design staff for the new division at Park Street, Camberley. Mr Norman Stott We record with regret that Mr Norman Stott, FCA, director and secretary of E.N.V. Engineering Co Ltd, died suddenly on October 28 at the age of 55. Mr Stott joined the company in 1943 and was made a director in 1953. Solartron Reorganization The Solartron Electronic Group Ltd have now been regrouped under one company structure, with administrative, R&D and sales functions centred at the group's head quarters at Farnborough, Hants. The Chessington factory has now become a production division, primarily concerned with electronic test instruments and assoc iated equipment. Mr E. R. Ponsford, for 14 years managing director of Solartron Laboratory Instruments Ltd, has been appointed deputy managing director of the group. Major emphasis for the future at Solartron is to be placed on the design and manufacture of electronic test instruments, industrial data handling equipment and analogue and industrial digital computers. The company today employs 2,000 people; its payroll in 1955 was 400. Anton/Lionel Products T. J. Sas & Son Ltd, 23 Upper Brook Street, London Wl, who represent the Anton/Lionel Electronic Corporation of America, have available the new catalogue listing latest additions to the Anton/Lionel range of electronics, nucleonics and connectors. Edghill European Agents H. W. Edghill Equipment Ltd have appointed Rotterdam- Air (Ground Services and Air Transport Co), Rotterdam Airport, Holland, as their sole European agents. Edghill Equipment, who earlier this year became a member of the Richard Threlfall Ltd group, state that the appointment of Rotterdam-Air marks the first step in a progressive policy to extend their activities overseas.
