7 September 1951 larger aircraft types, and many of these actuators will be displayed on the stand. One of the main achievements of the com- pany during the past year has been the development of complete 112-volt electrical systems for aircraft, which has included the development of 112-volt D.C. generators of 15 kW capacity, together with all forms of actuation, protection and switch gear associated with such installations. A new control switch has been developed for electrical starters for gas turbines, together with double and single high-energy ignition units designed to assist in the re-lighting of gas turbines at high altitudes. In addition the company manufacture a well-known range of turbo-starters. 1,000 3*3 'Newton ihductor-type alternator for <-, —' cyc/sec at 80 volts. \ Salford Electrical Instruments, Ltd., Silk Street, Salford 3, Manchester (Stand 17), have developed the Rotasol, an ingenious electro-magnetic unit capable of producing high torque throughout a limited angular travel. It is especially suitable for such work as step-driving multiple gangs of circuit switches. Teddington Controls, Ltd., Cefn Coed, near Merthyr Tydfil, South Wales (Stand 86), continue to manufacture their well- known range of inching controls, electro- hydraulic and magnetic valves, electro- magnetic jacks, solenoid-operated valves, time switches and pressure switches, etc. A section of the display will show the new range of Teddington gate-valves, variants of which will be displayed for use in air and fuel systems, and include the new range of hot-air valves for operation at the high temperatures and pressures common in aircraft heating systems. Ultra Electric, Ltd., Western Avenue, London, W.3 (Stand 150), will show a gas- turbine temperature-control system, for limiting the maximum temperature of the jet pipe or, alternatively, for controlling the temperature automatically to a variable selected datum. In addition, the company will exhibit a composite control system developed for use with the Bristol Proteus. The system provides remote positioning of the throttle valve and governing of com- pressor speed to close limits at any selected figure. A temperature-limiter to reduce fuel-flow is also incorporated, together with an overriding position control for use in the event of power failure in the normal system. Western Manufacturing Estate, Ltd., The Aerodrome, Reading, Berks (Stand 70), are designers and manufacturers of electrical actuators, trim switches, motors, indica- tors, etc., and will be showing examples of their range from the small unit with a nominal operating rate of 25 lb for a weight of 16 02 up to that with an operating rate of 3>ooo lb for a weight of 18 1b. The Type SS 125 Mk 9 electric motor measures but 2fin by 2jin yet has a power output of °i h.p. at 10,000 r.p.m. Westinghouse Brake and Signal Co., Ltd., 82, York Way, King's Cross, London, N.I High-power linear ac- tuator typical of the larp HJf^ WteJ C Rotax.l (Stand 140), will show examples of their light-weight "Westalite" rectifier units, in conjunction with many of the proprietary power units with which they are used. A separate rectifier assembly indicates the convenient simplicity of these selenium- compound units which, with the benefit of forced air cooling, offer a weight/capacity ratio of under 3 lb/kW.

Frankenstein and Sons (Manchester), Ltd., Victoria Rubber Works, Newton Heath, Manchester 10 (Stand 161), will be displaying their civilian type inflatable life- saving jacket as supplied to B.O.A.C. and B.E.A.; the latest-type inflatable life jacket for Service aircrew; and inflatable ex- posure-suit; Mk VI constant-wear immer- sion suit; a light-weight flying overall; inflatable life-jackets for naval aviation; and a new inflatable stretcher for ambulance aircraft. G.Q. Parachute Co., Ltd., Stadium Works, Woking, Surrey (Stand 1), are showing, as representative of their range of escape-type parachutes, the Mk 3 version for use with the Martin-Baker ejector seat. In addition, 25g Z-type safety harness will be on view, together with displays of braking and anti-spin tail chutes, paratroop equipment (including the X-type Statichute) and representative types of supply-dropping equipment. Integral, Ltd., Cousins Street, Wolvtr- hampton (Stand 53), manufacture hydraulic- ally-actuated shears for emergency entry into crashed aircraft. A light version is for continuous cutting round a section of air- craft skin, whilst the heavier type can deal with structural sections. Irving Air Chute of Great Britain, Ltd., Letchworth, Herts (Stand 35), are to display a variety of their approved parachutes for Service use, including pilot-seat, observer- chest, back, and back light-weight types, together with those designed for gliders, and for the Attacker and Canberra. Irving approved paratroop chutes and supply- dropping parachutes will also be shown, together with the company's automatic barometric opening device. M. L. Aviation Co., Ltd., White Waltham, Maidenhead, Berks (Stand 71), will include in their display a special Very-pistol mounting, whereby the pistol can be fired and re-loaded from the interior of a pressure cabin without loss of pres- surization or discharge into the cabin of noxious fumes. Another development is a harness release which is thinner than usual and incorporates a push-button that rises when unlocked and so gives a tactile as well as a visual indication of its condition. Martin-Baker Aircraft, Ltd., Higher Denham, Middlesex (Stand S), will show the latest version of the company's famous ejector seat. This latest design is fully automatic in action, and is claimed to be effective at any speed and under any accelerations that may be encountered, irrespective of aircraft attitude. The seat features combined parachute and seat harness, and a barostat is incorporated with the timing device so that the locks are not freed until the seat has fallen to a safe (breathable atmosphere) altitude. (A special drawing appears on page 320). R.F.D. Co., Ltd., Catteshall Lane, Godalming, Surrey (Stand 114), will have one of the more unusual stands, in that a representation is given of a cut-away furnished fuselage, through one of the "windows" of which continuous-sequence films will be shown to illustrate the pro- ducts of the company in action; these products include a range of inflatable dinghies and life-jackets, and first-aid and signalling equipment. The Schermuly Pistol Rocket Apparatus, Ltd., Spra Works, Newdigate, Surrey (Stand 60), will be showing a wide range of their pyrotechnic equipment, which includes ground-to-air control flares
