FLIGHT, SEPTEMBER 21, 1HH3 BRIEFLY " A STATE OF EMERGENCY " existed in Calcutta recently owing to the advance on the city of mosquitoes. Two years ago aeroplanes were used" to combat a similar invasion. AEROTLANES assisted Federal and City Police of Chicago to fight kidnappers, who were reported to be responsible for the disappearance of Jacob Factor, the financier. MR. F. H. JOLLY, who has been Secretary of the Eastern Counties Aeroplane Club since its beginning in January, 1931, and who was also during that time a Director and Chairman of the Board, has now left the Club, due to its reconstruction. With his past experience of this Club, he should be valuable, and anyone who wants a club secretarv should apply to him at 25, Landseer Road, Ipswich. THE first exhibition of the Air Force Artists' Associa tion will be held from October 2 to October 14 in the Whale Hall of the Natural History Museum, South Kensington. MR. T. ROSE has just been appointed Manager and Chief Instructor of the Northamptonshire Aero Club. THE Shackleton-Murray pusher, the S.M.I, has left Hanworth for Martlesham Heath to undergo its test for a C. of A. AN International Gliding school, under the direction of Robert Kronfeld, the famous Austrian glider, is to be opened shortly at Salzburg. The school will have its own workshops for the provision of up-to-date machines. It will be established near the Gaisberg in Salzburg, which is considered by experts to be the best gliding ground in the world. * • • • Vickers, Ltd., and Its Activities THERE would appear to be a certain amount of mis understanding in some foreign countries with regards to Vickers, Ltd. In order to clarify the position, we append a brief statement of the position. Vickers, Ltd., is a holding company, with its interests confined to the follow ing groups: — (1) Armament, shipbuilding, steel and engineering, through Vickers-Armstrongs, Ltd. (2) Rolling-stock, through Metropolitan-Cammell Car riage, Wagon & Finance Co., Ltd. (3) Aviation, through Vickers (Aviation), Ltd. (4) Sundry British industrial undertakings wholly con trolled bv Vickers, Ltd. Vickers-Armstrongs, Ltd., has resulted from a fusion of the shipping and armament interests of Vickers and Sir \V. G. Armstrong, Whitworth & Co., Ltd., and the English Steel Corporation, which itself was a combination of the steel interests of Vickers-Armstrong and Cammell Laird & Co, Vickers-Armstrong are not associated with any other companies in the Armstrong-Whitworth group, but they have a small subsidiary company in Spain and minority holdings in companies in Spain, Japan and Roumania. The Metropolitan Cammell Carriage, Wagon & Finance Co. resulted from a fusion of the rolling-stock interests of Vickers and.Cammell Laird. Vickers (Aviation), Ltd., consists of Vickers (Aviation), Ltd., at Weybridge, and the Supermarine Aviation Works (Vickers), Ltd., at Southampton. This company has no foreign associated concerns. In 1926 Vickers sold the whole of its interests in Canadian Vickers, Ltd., and that company still carries on business in Canada under its original name. Similarly, Vickers disposed of the whole of its control in Metro politan- Vickers, Ltd., and they now only hold a minority interest, with participation in control or management. They also have a minority holding in the Vickers-Com- monwealth Steel Co. in Australia, but do not control that undertaking. Vickers (Ireland), Ltd., is, however, a sub sidiary of Vickers-Armstrongs, Ltd, It will be seen, therefore, from this information, which we have received from Vickers, Ltd., that there is no truth in the assertions, which have appeared from time to time in foreign newspapers, that Vickers were interested in armament firms throughout the world like those of Skoda, Schneider and Bofors. 958 Townend Rings IN a little booklet, produced by Boulton & Paul, 139, Queen Victoria Street, E.C.4, the difference that the Town- end Ring makes to a machine is illustrated. It is claimed, and nowadays generally accepted, that a Townend Ring can reduce the resistance of air-cooled radial engines by about two-thirds. The ring is also used as a collector for exhaust in place of the rather cumbersome exhaust ring of earlier radial engines. The Westland " Wapiti's " speed was raised more than 10 m.p.h. by fitting a Town- end Ring to its " Jupiter." An Armstrong-Whitworth " Atlas," with a " Panther," was speeded up by about 20 m.p.h.; an Airspeed " Courier," with Armstrong- Siddeley " Lynx " about 15 m.p.h.; a Boulton & Paul " Sidestrand," 2 " Jupiter " VIII F, about 12J m.p.h., and a Morane fighter, about 14 m.p.h. Patents The procedure of obtaining patents is a bit of a mystery to most people and supposed to be a long and complicated business. Mr. B. T. King, C.I.M.E., of King's Patent Agency, Wardrobe Chambers, 146A, Queen Victoria Street, E.C.4, has produced an interesting little booklet which explains the matter in a few pages. The booklet explains that before taking out a patent, enquiry- should be 'made, by study of patent records, whether a patent for the particular invention has not been taken out before. For instance it is popularly supposed that Dunlop was the inventor of pneumatic tyres, whereas in reality a patent for a pneumatic tyre was taken out in 1845, 43 years previous to Dunlop. m m m m PUBLICATIONS RECEIVED Compression-Ignition Engines for Road Vehicles.
