FEBRUARY 2, 1939 AERODROME EQUIPMENT MAKERS (CONTINUED) *x~ i/»»r CAftmAoe CA£ f /2TAZT.V.V tvf/£AT r'ft* MRNMW A/o&r/AV rfww AV ewst er *&£ tenance paints for aerodrome and other buildings, and finishes for all types of aero drome equipment. Special attention has been given to the development of paint for camouflaging aerodromes, factories, etc., and technical advice can be given on all camou flage problems. NORTHERN ALUMINIUM CO., LTD., Bush House, Aldwych, London, W.C.2.—A product of this firm of alloy specialists is " Moral " aluminium paste, an important ingredient of aluminium paints for preserva tive and decorative purposes. PAK PARACHUTE CO., LTD., 175a, Streatham Road, Mitcham, Surrey, are makers of wind indicators, wind cones, signal cones, aerial kites, and allied ground equipment for aerodromes. POLES (1938), LTD., Nickel Works, Erding- ton, Birmingham.—The accompanying draw ing gives details of a new tower for mount ing aerodrome obstruction lights. It is the result of much experimental work by this company, with the collaboration of the Air Ministry. Mounting heights of over 100ft. can be attained, and guying or stay ing is entirely eliminated. The structure is made up of tapered sections, hot-spelter- galvanised inside and out, and strained to gether to a glove-like overlapping fit, as in the other well-known varieties of " Adastra " poles. The winding gear and conductor are housed inside the pole itself, and are completely weatherproof. The raising and lowering of the light is effected by means of a travel ling platform with phosphor-bronze wheels, operating on a guide rail of galvanised tee section. No drilling, riveting, or '-welding is necessary on^erection. The "drawing is of an actual pole erected at Croydon for the Air Ministry. PYRENF. CO., LTD., Great West Road, Brentford.-—These well-known manufacturers of fire extinguishers list a variety of fire- fighting equipment specially -suitable for aerodromes, ranging from small hand extin guishers to trailer-type fire engines; foam equipment is a speciality. RADIO TRANSMISSION EQUIPMENT, LTD'., 45, Nightingale Lane, Balham, London, S.W.12, are contractors to all Government Depart ments. They are manufacturers of aircraft radio equipment, including homing receivers, navigational beacons and beacon receivers for blind landing; aircraft standard transmitters «f 50 and 100 watts output on long and r/fiv ef rop.

RANSOMES & RAPIER, LTD., Ipswich and London, are makers of Rapier mobile cranes with rubber-tyred road wheels for aero drome and hangar service. The cranes are petrol-electric or Diesel-electric, and are made in four types each, to lift loads from 1 to 6 tons. At the present stage catapult launching hardly enters into the sphere of aerodrome operation, but it is worth noting that the tumour Rapier catapults are made for land as well as marine use. A recent Rapier development is the Rapier-Irvine heat-treatment machine for soil road construction. This machine, travel ling over virgin soil, leaves in its wake a trail of broken-brick-like material which, when consolidated by rolling, has the general characteristics of a good gravel road. RANSOME, SIMS AND JEFFERIES, LTD., Orwell Works, Ipswich, are manufacturers of machinery for preparation and mainten ance of aerodromes, i.e., gang-mowers specially designed for cutting aerodromes, mole-drainers, disc harrows, drag harrows, and land levellers. They also make trans- ]K>rtable hangars, etc. REID AND SUIRIST, LTD., Shannon Corner, Kingston By-pass, New Mfclden. — This famous firm of aeronautical instrument makers also make two items of interest to aerodrome owners—a folding 12ft. carbon- steel grab-hook for fire rescues (with an extension cable enabling a number of helpers to assist in the pulling), and, secondly, an aircraft picket of a novel type; in this, two picket rods are coupled together at right angles by a cross-piece; one picket is first driven into the ground at an angle of 45 degrees, sliding, through the cross- piece; the other is then driven into the ground at right angles to the first. High resistance to a pull from any direction is the result. R.F.D. Co., LTD., 17, Stoke Road, Guild ford, Surrey.—This firm of balloon and flota tion gear specialists also make such aero drome equipment as wind socks, including an illuminated type. ROTAX, LTD., Willesden Junction, London, N.W.10.—Rotax equipment for aerodromes consists of two items, the Rotax-Harley portable floodlight and the Rotax motor starter truck. The former consists of a single nin. 250-watt Harley lamp adjust ably mounted on top of a 5ft. pedestal on a robust three-wheel truck carrying storage batteries and a petrol-driven generator. The starter truck has been designed to provide a source of power for aircraft engine electric starters, either at the flying field or in engine test houses. By merely plug- ping into the ground starting socket and by pressing a button, the engine can be cranked over, and this process can be re peated on any number of engines without any fear of discharged batteries. The equipment consists essentially of a double-wound transformer, a full-wave bridge-connected Selenium metal rectifier, and a starting and overload protection con tactor, push-button controlled, also a series parallel switch to enable alternative outputs of 12 volts 300 amperes, or 24 volts 150 amperes. The truck is designed, if required, to be operated on overloads up to 100 per cent, for periods of five minutes, provided that intervals of ten minutes are allowed for the equipment to cool down. SELF-PRIMING PUMP AND ENGINEERING Co., LTD., Edinburgh Avenue, Trading Estate, Slough, are makers of petrol pumps of all types, including electrically driven remote unit pumps.
