364 •='••'-;• •-.•• NEW from the ACCESSORY INDUSTRY . .. differs mainly from the previous Travellerseries in having semi-open styling of the side-arm structure. Microcell also manufacture rocketlauncher packs with loadings for 14, 24 or 37 rockets. A feature of these is that theinternally carried types have no expendable parts and their life is in excess of that of anoperational aircraft. Full-scale ground and air trials at up to supersonic speeds haveproved successful. MI coma wx Plessey's dual-purpose constant-speed drive starter. Drive is mechanical and by bleed air Among the units manufactured byMicrocell Electronics Division are a tran- sistor test set, stabilized power supplies, atransistorscope type 175, and dielectric test set. All these units are new and have beendeveloped primarily for laboratory use. The stabilized power supply type 166 isproposed for use with scintillation counters and similar instruments; there are threeranges of output voltage between 500V— 1.2kV, lkV—2kV, and 2kV—3kV. The dielectric test set type 160 is a toolfor obtaining information on the behaviour of ceramics, plastics and other materialswhen exposed to micro-wave radiation and high temperature. Its design was based ona requirement that it should be simple in operation, producing correct answers withminimum calculation. The transistorscope type 165 makes useof modem semiconductor circuit tech- FLIGHT, 2 September 1960 niques to obtain a fully portable self-contained unit weighing 101b and measur- ing 12iinx7inx8iin. Performance issaid to be equal to many commercial oscilloscopes of greater size, weight andprice. Finally the test set type 156 is the latestof its type in the Microcell range and is designed to measure: accurately the para-meters of PNP and NPN transistors. The company state that it is particularly suitablefor the selection of matched sets of transistors. Morfax Ltd Stands for ground servic-ing, road transport and air-freight of aero engines have this year been developed forthe Tyne, Avon, Conway, Dart and Eland. The transport stand for the Tyne isdesigned to be stowed in the freight hold of the Vickers Vanguard; an hydraulictow bar has also been produced for the same aircraft. The strip/build stand forthe Tyne, Avon and Conway is an improved hydraulically elevating design forvertical asembly and dismantling and the Dart stand is a lightweight unit to accom-modate these engines when they are air freighted. D. Napier & Son Ltd The companyhave recently received exclusive rights from the Sierracin Corporation of Bur-bank, California, to manufacture, use and sell the Sierracote process in the UK andEurope. Sierracote is a transparent con- ductive coating used for heating aircraftwindscreens and canopies. It can be applied to glass and all plastic materialsand has industrial applications. Napier visualize it as a complementary process tothe Napier Spraymat de-icing system. During recent months (see Flight,August 5) the company have developed Spraymat for helicopters. It is applicableto both main and tail rotors. Louis Newmark Ltd Both airborne andground equipment has occupied Louis Newmark during 1960. In the formercategory is an obviously advanced heli- copter autopilot designed for larger heli-copters with power-assisted controls. With its auxiliary equipment it forms a systemwhich can navigate an aircraft in forward flight, bring it to the hover and maintainthis condition for long periods. Into the autopilot can be incorporated an inertia!navigation system "for use over tidal waters," a radio altimeter and a Dopplerground/speed device to bring the aircraft to hover from forward flight. Controlactuation is effected by four servo-driven actuators which operate pilot valves in thehydraulically-operated flight control link- age. A gyro vertical senses both pitch androll displacements, providing both angular and rate signals in these axes. Normal Morfax hydraulically elevated platform for Rolls - Royce Avon, Tyne and Conway overhaul Microcell MD102 Executive De-Luxe Series 1 twin seat, with integral cabinet altitude control is by barometric capsulebut, as noted above, a radio altimeter can be used or even a pendant cable. Headingis maintained by another gyro within a self-contained compass system. This mayoperate either as a free gyro or slaved. Monitoring facilities in both autopilotand compass system are provided for the pilot and any or all of the four controlchannels may be switched out of the system.Another autopilot or helicopters pro- duced by Ncwmark weighs 501b. It oper-ates on three axes, provides basic stability and has manoeuvre heading and height-hold facilities. Monitoring signals are derived from rate gyros and pick-offs inthe appropriate flight instruments. These signals are amplified in all-transistoramplifiers and fed to servo motors which operate directly on to the flying controls. Manoeuvring signals are derived fromsensing devices in the control runs. When the autopilot is not engaged these becomeeffectively locked and thus dispense with the backlash which was inherent in someearlier types of autopilot. There is fail safe and full over-ride and the effects of arunaway are reduced by restriction of servo authority when the helicopter is notunder the pilot's immediate control. The ground equipment which has beendeveloped is a response test set. The instrument consists of two units, a VLFoscillator and an oscilloscope. It enables frequency response characteristics of aservo system to be plotted by measuring the variations of phase change throughoutthe system. Normalair Ltd Oxygen in liquid formhas now become firmly established as the most economical way of transporting it inan aircraft. It is equipment for this pur- pose and vapour cycle cooling thatNormalair are supplying for the VC10. The liquid-oxygen converters have acapacity of 30 hires and incorporate a crew reserve circuit which automaticallyguarantees a reserve supply regardless of passenger consumption. The VC10 maybe the first civil passenger aircraft in the world to be fitted with liquid oxygen stor-age equipment; it is being incorporated to comply with anticipated revisions of theAir Navigation Regulations. For the same aircraft Normalaii havedeveloped an electro-pneumatic pressure control in which electrical signals are usedto actuate pneumatic discharge valves. System sensitivity is said to be particu-larly good. Actuation of the system is achieved by three sensing elements eacnconsisting of a capsule operating a trans- ducer. Signals from the latter are taKento an amplifier where they are commnea to form a resultant control signal to medischarge valve. In the VC10 the vapour
