15 DECEMBER 9, 1926 VICKERS Limited. IN such an immense organisation as that of Vickers, Ltd., itis to be expected that, in addition to their wide range of aircratt tvpes, their many factories produce much of specialinterest to aviation, both from the military and civil points of view. The following notes will indicate, in some slightdegree, the wide scope of their manufactures. FITTINGS FOR THE PETROL, OIL AND WATERSYSTEMS of an aircraft must, of necessity, be as near Vickers Reid Indicator. perfection as can be attained. Vickers have devoted a verygreat deal of attention to the development of a complete range of such fittings. The new Vickers patent PETROL COCKSare now made almost entirely of Duralumin, the plug being of Vickers Immaculate Steel (Rustless) with bronze seating.These are available in " two-way," " three-way " and "four- way " form, and in sizes from i-in. B.S.P. to 1 in. B.S.P. AJ-in. two-way Cock weighs 5 ozs. only. Other fittings include Oil and Water Drain Cocks, Petrol Non-Return Valves, FlowIndicators, Relief Valves, Oil Relief Valves, Water Flushing Valves, Petrol Filters, Centrifugal Petrol Pumps(wind driven), the Mark II* (3-in. impeller), and the Mark VI (2-in. impeller), etc. The VICKERS (patent) OLEO PNEUMATICUNITS for UNDERCARRIAGES AND TAIL SKIDS are now standard components of all theiraircraft types. This system of suspension has been brought to a state of perfection after veryextensive experiments. It employs compressed air as the resilient medium in the place of thesomewhat perishable rubber-cord shock absorber used in the past. They are equally efficient fortwo-wheeled or for four-wheeled chassis, and are made in five standard sizes which cover most existing types ofaircraft. Special units can be designed for extraordinary requirements. It is interesting to note that many aircraft constructors abroad,in France, Germany and in the UnitedStates, are embodying the Vickers Oleo Unitin their suspension systems. Other aero speciali-ties include STREAM- LINED WIRES andSWAGED TIE- RODS, TUBING ofSPECIAL AIR- CRAFT STEELS(made at Sheffield), METAL COUPLINGSfor petrol pipes. Ad- justable PIPE CLIPS(" Malleville " pat- ents), and the Vickerspatent UNIVERSAL PULLEY ANDGUARD, for bomb gear and for otherlight duties. The Pul- ley Unit, which is of Duralumin, can be supplied to containfrom one to twelve pulleys with a single steel fixing bolt. Passing to items of separate equipment, a most interestinginstrument is the REID CONTROL INDICATOR, which gives to the pilot an immediate indication of any departurefrom his set course. The Reid Control Indicator, it may be mentioned, is part of the present standard equipment of everyaircraft operated by Imperial Airways, Ltd., and its great value has recently been specially commented upon in anofficial report of two officers of the Danish Military Flying Corps who, respectively, flew from Copenhagen via Calcutta,Rangoon and China to Yokohama and back to Copenhagen via Siberia and from Copenhagen to Rangoon and backto Copenhagen. The VICKERS-DAVIS NAVIGATION LIGHTS(Light Pattern), produced from the Weybridge factory, are considerably lighter than the standard " Davis "Navigation Lights of which Vickers also possess the commercial rights, and which are standard equipmentfor Royal Air Force machines. They are designed to meet all the requirements for Identification Lampsfor night-flying aircraft, as laid down by the Interna- tional Convention of 1919. They include patentedBracket Mountings and a patented dual filament electric lamp. The full set covers Port and Starboardlights Head and Tail Lamps, and, for Seaplanes, Anchor Light and Out-of-Control Lights. Vickers alsomanufacture ELECTRIC GENERATING EQUIP- MENT for aircraft lighting and heating systems,SANITARY EQUIPMENT for passenger-carrying aircraft, and ADJUSTABLE SEATS FOR PILOTAND NAVIGATOR which can be raised or lowered during flight. The " EAGLE " AUTOMATIC ELECTRIC AIR CAMERA,of which a full description was given in the issue of FLIGHT Vickers Eagle Camera. VickersGun Ring. dated November 11, 1926, is of the greatest interest to allconcerned in air photography, either from the point of view of the civil surveyor or from the military reconnaissanceaspect. This camera is manufactured by the patentees, Messrs. Williamson Manufacturing Co., Ltd., of WiUesdenGreen, N.W., for whom Vickers, Ltd., are sole selling agents. Another camera, but for an entirely different duty, is the" HYTHE Mk. Ill " GUN CAMERA (the product of Thornton Pickard Manufacturing Co., Ltd., of Altrincham). for trainingin air gunnery, recording, on a film, the results of the pupils' shots.Vickers also supply the standard Air Force gunnery training apparatus known as the " ROCKING FUSELAGE," the" FIXED INSTRUCTIONAL FUSELAGE," the |TH SCALE DEFLECTION TARGET " (for use on the 25 yardsrange), and the " AERIAL GROUND TARGETS." As regards Armament, with which the name of Vickers,essentially, is associated, space does not permit a description of the many items which come under this heading, but mentionshould be made of the VICKERS RIFLE CALIBRE AIR- CRAFT GUNS, Belt Feed and Drum Feed, the VICKERS5-IN AUTOMATIC GUN (all manufactured at the Erith factory), and the range of AIRCRAFT BOMBS, of 20 lb.,50 lb., 112 lb., 230 lb., 520 lb., and 550 lb. types) made and filled at the Dartford Works where also are producedCARRIERS for all these Bombs, and the VICKERS-SCARFF WIND BALANCED AIRCRAFT GUN MOUNTING, whichis a development of the well-known " Scarff Ring " used during and since the Great War in almost every Air Force in the world. Vickers Dartford factory also produced a comprehensiverange of PYROTECHNIC SIGNALS and apparatus for their discharge. 810o
