FLIGHT, MJUICH 1, 1934 FOR SHORT-WAVE WIRELESS TESTS : Marconi Type A.D. 43A transmitter installed in a Bristol" Bulldog " single-seater fighter for recent short-wave tests between the Marconi experimental station at Croydon and the aeroplane in flight over the Bristol district. The corresponding receiver, TypeA.D. 44A, is mounted at the back of the transmitter. This photograph shows the method of instal- lation, the aerial system, and the Marconi-Stanley one-horse-power engine and flexible drive used forrunning up the generator on the ground for testing and adjusting purposes. " Aluminium Sections " A VARIETY of uses for aluminium of angle, bar, channel and numerous other sections is immediately suggested on glancing through the booklet " Aluminium Sections," which has just been produced by the British Aluminium Co., Ltd., of Adelaide House, King William Street, E.C.4. These extruded profiles, which usually are made in pure metal of soft temper, show a strength of five to six tons per square inch. In this condition they are easily shaped to the required form. If greater strength is required, smaller sections may be work-hardened by a subsequent drawing process. For rapid servicing EVERYONE knows that pang of economical consciencewhich assails the pilot while having his oil supply re- plenished from the small oil cans. He always feels thathe loses a good deal of oil in each can if he hurries the S3 £5 BRIEFLY Cirrus-Hermes.—At the end of last month Cirrus-Hermes,Ltd., transferred their activities to Brough, East Yorks. For the future, therefore, all correspondence should beaddressed to Cirrus-Hermes, Brough Aerodrome, Brough, East Yorks. American Instruments.—We have received from theKollsman Instrument Company, Inc., of 1, Junius Street, Brooklyn, New York, a catalogue of the instruments pro-duced by the company for use in aircraft. These include altimeters, level flight indicators, air speed indicatois,tachometers, compasses, gauges and thermometers. A Lodge Success.—Lodge Plugs were used in the " GipsyMajor " engines of the De Havilland " Dragon " in which M. Robert Germain, M. Descamps and M. Pierre Laveauxrecently made the first successful flight across the Sahara from Algiers to Lake Chad. Clacton Landing Ground.—A new fence on the south-west boundary of the landing area has reduced the run north-east south-west to 343 yd. Insurance.—We have received a brochure giving detailsof a very interesting and unusually comprehensive insur- ance scheme which has been compiled by Mr. C. Biardand R. H. Stocken, of 18, Regent Street, London, together with the Manufacturers' Life Insurance Co., British Avia-tion Insurance Co. and the Employers' Liability Assurance Corporation. This should certainly satisfy those officersin the R.A.F. who like to pay one premium for all of their cover. Chamier Gilbert-Lodge Insurance Department.—Underthe direction of Air Commodore C. J. A. Chamier this company has now opened an insurance department whichcovers every form of risk. A booklet fully explaining the advantages to be gained by placing insurance through abroker has been issued by the company. mechanic when pouring it out. The idea of bulk storage,therefore, found great favour where it was installed but that also' has its difficulties. It has been found that thewastage is large both when filling large containers and also when carrying the oil from the bulk supply to themachine. Alexander Duckham & Co., Ltd., the makers of" Adcol " lubricating oils, whose N.P.5 oil is widely used for aero engine lubrication, have now evolved a veryneat form of portable pump which can be wheeled up to the aeroplane so that the oil can be pumped direct intothe oil tank or sump. This pump has the great advant- age that its source of supply is the ordinary ten-gallonoil drum of commerce. One of these drums is carried on the sort of wheelbarrow base of the pumj) and can bechanged for a full drum in a few seconds when necessary. This makes a light and easily handled method of oilsupply, which has already proved its advantages to users at many aerodromes. S3 SIS SIS A Recovery.—Mr. W. D. Campbell, whose illness inCairo we reported at the time of the Oases Meeting in Egypt, is now fit again. He left for New York early thisweek. After recuperating from his severe illness in Luxor and Aswan, he visited Nairobi, travelling by Imperial Air-ways, before returning to England. Maj. Mealing's Marriage.—Maj. R. H. S. Mealing is,despite his accident, being married at Twickenham to-day (Thursday, March 1). After the ceremony—on a stretcher-he will return to his bed, to which he will have to keep for some months. We offer him our best wishes for his futurehappiness and a speedy recovery. Phillips & Powis and " Cirrus " Engines.—Phillips &Powis, Ltd., of Reading, have acquired the manufacturing rights of the " Cirrus II " and " Cirrus III " engines, andhave taken over all stock, jigs, patterns, drawings, spares, etc., relating to these engines. A Comper Recruit.—Mr. G. A. Lingham, who wasformerly with Maj. Jack Savage (" Sky-Writing "), has now joined the Comper Aircraft Co., Ltd., as SalesManager. A Well-earned Rest.—The many friends of Mr. T. W.Graham, Advertising Manager of the Vacuum Oil Com- pany, will learn with regret that he has been compelled,for reasons of health, to leave business for three months. British Dope for Central Europe.-—We learn fromCellon, Ltd., of Upper Ham Road, Kingston-on-Thames, that in the face of keen competition they have succeededin securing an order for aircraft dope from Bulgaria.
