Stored-air StartingI N Flight for August 26 last year we described in some detail therange of stored-air aircraft-starting equipment marketed under the name Jetstart. The makers—I.V. Pressure Controllers Ltd, of683 London Road, Isleworth, Middx—have recently released new details about the latest trolley unit in the range, the Jetstart Mk 5.This equipment, which provides a source of high-pressure air con- trollable to fine limits, is capable of starting four engines by supplyingeach with 801b of air at 60 F, 451b/sq in gauge for 25sec. The air supply comes initially from 24 Chesterfield bottles witha total capacity of 21 cu ft. Working pressure for each bottle is 3,6OOlb/sq in gauge (tested to 6,0001b/sq in).When brought into operation, the initial pressure can be con- trolled down to a final 3001b/sq in. Condensate can be drained fromthe bottles through a valve at the rear of the unit. A maximum of 3,6001b/sq in is available from the high-pressuredistribution panel and a regulator-controlled 5-75Olb/sq in from the low-pressure source. Air both entering and leaving the unit isfiltered to 25 microns. Should a sudden surge of air cause internal pressure to rise abovethe pre-set maximum, a spring-controlled poppet valve, with variable settings from 1,300 to 4,0001b/sq in, gives the necessary relief. Otherspring-loaded relief valves, with settings variable from 10 to 1501b/ sq in, are fitted to the high-pressure bottles. The Jetstart is mounted on a four-wheeled trolley with steerablefront wheels which are automatically braked when the tow-bar is allowed to fall into the parking position. The unit is 60in high and,excluding tow-bar, lOlin long. Weight fully loaded is 2.5 tons. Space is available within the unit for a heat-exchanger shouldone be required. New Castrol Directors THREE new directors, Messrs L. Colkett, K. C. McCarthy andG. H. Thornley, have been appointed by Castrol Ltd, parentcompany of the Castrol Group. Mr Colkett joined the company in 1934 and became secretary ofCastrol Ltd (then C. C. Wakeneld & Co Ltd) in 1955; Mr McCarthy joined Castrol in 1930 and after several years in the publicity depart-ment transferred to the motor oils department as assistant manager, being made sales promotion manager of the Castrol division in1956: he is to become general manager of this division on January 1 next year; Mr Thornley, who joined Castrol 36 years ago, has beengroup technical manager since 1951. Electronics Directory Amendments r"THE directory of principal manufacturers of electrical and elec- 1 tronic equipment in Flight for October 5 noted that LucasGas Turbine Equipment Ltd make electrical accessories and igni- tion screen harness. The entry, however, should more correctlyhave read "Research, design, development and manufacture of fuel pumps and associated control systems, combustion equipment,space and anti-icing heaters, fuel boost-pump systems, hydraulic motors and pumps for aircraft and guided missiles." The list should also have included Rotax Ltd, well known asmanufacturers of a wide range of electrical equipment of all types, including AC and DC generating and starting systems, motors andcontrol equipment. • • * Westinghouse Brake & Signal Co Ltd, of 82 York Way, London,Nl, point out that their electronic products listed in the above- mentioned directory should have included the following: silicon-controlled rectifiers, silicon diodes and selenium rectifiers for air- craft; transformer/rectifier units and control circuits; and mains-operated ground services equipment. * * * The same review included, inter alia, the names of a number ofmanufacturers of batteries. To these should be added Cadmium Nickel Batteries Ltd, Spedant Works, Park Royal Road, LondonNWJ0, who inform'us: "We have supplied some thousands of bat- teries through Ministry of Aviation contracts for stand-by opera-tion of UHF sets. We have also supplied, through the same agency, a large number of batteries of different shapes and sizes for missileand potential space applications. These are, of course, in addition to our normal supply of main aircraft batteries." IN BRIEF Mr E. G. Barber, BSC, AFRAes, has been appointed group educationofficer for British Aircraft Corporation.
