FLIGHT, JULY 29, 1932 Vhe Industry A GUIDE TO AERODROME LIGHTING ""THE British Standard Institution, of 1 28, Victoria Street, S.W.I, have recently published a pamphlet, price 2s. 2d. post free, entitled " A Guide to Aerodrome Lighting." This is arranged with the approval of the Air Ministry and is preparatory to the publication of a British standard speci fication. It seems somewhat early to lay down the law in an arbitrary fashion as to the requirements for aerodrome and airway lighting, but there is no doubt that the establish ment of a standard should greatly assist the development of commercial aviation along economical lines. The committee's recommendations as re gards aerodrome location beacons, aerodrome boundary lights, aerodrome wind indicators, obstruction lights and landing lights do, as they point out, go beyond the existing regulations, the reason being that these regulations were drawn up immediately after the war and before civil aviation activities had really commenced. By these recommendations it is intended to anticipate as far as possible inter national practice of the future. FLYING AND BUSINESS ""THIS month's Fetters News, the house organ of Fetters, Ltd., and the Westland Aircraft Co., contains details of an interesting trip made by Mr. Haywood, their representative for Central America. This gentleman travelled over 9,000 miles in Vene zuela, Columbia, Mexico, Cuba, Jamaica and the whole of Central America in under three months. The success and rapidity of his journey was solely due to the use of aircraft when ever this form of transport was available. VICKERS IN CANADA THE Vickers Supermarine Rolls- Royce S.6B. seaplane has been shipped to Canada, where it will be shown during the Canadian National Exhibition at Toronto in August. Another interesting exhibit in the sec tion of the exhibition devoted to Vickers' interests will be a model of the Vickers " Vimy " Rolls-Royce aircraft in which Sir John Alcock and Sir Arthur Whitten-Brown made the first direct Trans-Atlantic flight on June 14-15, 1919. A special brochure is to be issued at the exhibition on be half of Vickers, Ltd., and Associate Companies, which forms a very attrac tive catalogue of the main productions of this vast organisation. Three pages are devoted to aviation, on two of which the " Viastra " forms the main subject matter, while on the third re ference is made to their subsidiary, the Airship Guarantee Company, which built R.100. In view of the import ance to British aviation of large flying boats, the Vickers Supermarine pro ducts are naturally of great interest to our Dominions, and some reference will be found to the boats made by this firm on the second page devoted to aircraft. HOFFMANN BALLBEARINGS LJOFFMANN ballbearings were again * •*• used in every single aero engine of the King's Cup race, and also in the engines and gear box of Lord Wakefield's Miss England HI in which Mr. Kaye Don has recently broken the world's water speed record with a speed of 119.81 m.p.h. Those wish ing to do business with this firm should note that the works will be closed from 5 p.m. on Friday, July 29, until Wednesday, August 9. The Offices and Despatch Department will, how ever, open on Tuesday morning, August 2, and a small staff will be in attendance on Saturday morning to deal with urgent orders. A NEW FLAME TRAP C'IRES have on many occasions been ^ caused in aircraft by a flame blow ing back through the carburetter air intake. Of particular interest is the new " Amal " Flame Trap, which en tirely eliminates any risk of blowing back when it is attached to the air intake. Amal, Ltd., the makers, are a. subsidiary of Imperial Chemical In dustries, Ltd., Millbank, London, S.W.I, and this flame trap of theirs is a cup-shaped attachment containing a fiat corrugated ribbon of special non- corrosive metal wound in the form of a flat spiral. The series of small tri angular tunnels thus left entirely pre vents the passage of any flame, while at the same time admits the air freely. This trap has been approved and adopted by the Air Ministry for use on passenger-carrying aircraft, and a further modified form has been pro duced as suitable for marine engines, to eliminate the risk of fire in motor- boats. IN THE CAUSE OF WELDING J UDGING by the amount of literature on welding received by FLIGHT recently, there is clearly a campaign to advance the utility of welding. " Sif-Tips " is a new quarterly house journal, published by the Suffolk Iron Foundry (1920), Ltd., of Stowmarket, and intended to give hints and tips for the welder of to-day. It is an unpre tentious small journal in style and appearance, but its contents are prac tical and sound. To explain the possi bilities in the difficult process of weld ing cast iron is one of the special aims of the publishers, and in one article it is pointed out that success in this class of work depends to a great ex tent on the amount of knowledge possessed by the welder as regards the composition and mechanical character istics of this metal. Companion litera ture to " Sif-Tips " is " Acetylene Flames," published by the Acetylene & Welding Consulting Bureau, Ltd., Grand Buildings, Trafalgar Square, W.C.2. This Bureau is engaged in the task of keeping abreast with all the advanced developments in the appli cation of welding, both abroad and at home, and spreading information col lected for the benefit of those con cerned. They have a workshop wherein practical demonstrations are given, and they show films periodic ally for all interested in the subject. Their present booklet is issued as a simple guide, mainly for students. It mentions, incidentally, of Duralumin, that it is an aluminium alloy suitable for welding, but requiring subsequent heat-treatment in order to develop its strength. A pamphlet is also issued by this Bureau giving a description of an important innovation in oxy-acety- lene welding, for which it is claimed that the speed of welding can be in creased 50 to 60 per cent., reducing the cost by 25 to 30 per cent, at the same time. The Keel Multi-Flame Blowpipe is responsible for this in crease, and it incorporates the right- hand (or backward) welding method which was introduced a few years ago and increased welding speed by 30 to 40 per cent. Part of the Bureau's present policy is to try to advance the practice of the right-hand welding method in this country.
