820 FLIGHT, 18 December 1953 THE INDUSTRY Return to the Industry AFTER two years' voluntary service with the Ministry of **• Supply as Director-General of Electronics Production, Mr. N. C. Robertson, M.B.E., F.R.S.A., A.I.E.E., M.Brit.I.R.E., M.I.P.E., has now resumed his civilian duties as deputy managing director of E. K. Cole, Ltd. Many senior members of the Ministry of Supply, including Sir James Helmore, K.C.M.G., the Permanent Secretary, attended a private luncheon party held in London recendy to bid farewell to Mr. Robertson. Mr. E. K. Cole, chairman of E. K. Cole, Ltd., and other directors of the company were present at the luncheon to welcome back Mr. Robertson to their organization. First entering the radio industry in 1924, Mr. Robertson joined E. K. Cole in 1930 and was successively chief inspector, produc tion manager and works manager. He was appointed to the Board in 1943 and was made deputy managing director two years later. A High-speed Low-altitude Camera TLLUSTRATED below is the Vinten F.95 low-altitude » reconnaissance camera, designed for securing high-definition pictures of ground targets from fast-flying aircraft. The instrument uses 70mm negative, which permits considerable magnification without loss of defi nition through grain size; sufficient film for about 500 ex posures is contained in quickly inter changeable casset tes, which can be loaded widiout re moving the camera from its mounting and without the necessity for threading. Two Taylor, Taylor and Hobson lenses are fitted, 4in f/2 and 12in f/4, giving angles of view of approxi mately 18 deg and 6 deg respectively. Both fit the iris-diaphragm remote-control unit which, electrically operated, gives a choice of three apertures on selection by a switch. A continuous-running focal plane shutter gives exposures of 1/1,000th or 1/2,000th sec, for camera speeds of four and eight pictures per second respectively. The camera drive is from the aircraft 24v supply. A thermostatically-controlled heater is incorporated, and the working range of the camera is stated to be - 20 deg C to +50 deg C, while a range of — 40 deg C to +70 deg C will not harm the instrument. Overall dimensions are 5fin wide by 9Jin high by lliin (with 4in lens) long. Weight, with loaded cassette, is 15 lb 11 oz. Up to diree F.95 cameras can be remotely controlled, either independently or together from a small panel. The panel controls the running of the cameras; carries switches for the heaters; gives a choice of four or eight exposures per second; indicates the amount of film exposed; and has a three-position diaphragm- control of each camera. The makers are W. Vinten, Ltd., North Circular Road, London, N.2. C02 Cooled Cutting Tools ' I 'HE new "CeDeCut" technique of using carbon dioxide as a •*• machine-tool coolant was demonstrated at the opening of the East Kilbride factory of Rolls-Royce, Ltd., on November 20th, when gas-turbine shafts were shown being machined with and without the use of a liquid CO 2 jet. The method demonstrated and the apparatus used were developed by the Carbon Dioxide Co., Ltd., in association with the central research department (engineering section) of the Distillers Co., Ltd., who have made patents application. With die collaboration of the Ministry of Supply, a number of firms (including Rolls-Royce) have carried out production tests with the new technique, and it is stated that most encouraging results have been obtained in a series of difficult cases, particularly in dealing with the modern tough and heat-resistant alloys, including Nimonic and nickel-chrome-molybdenum steels. Technical information on the process is obtainable from the Carbon Dioxide Co., Ltd., Great Burgh, Epsom, Surrey. The Vinten F.9S camera. "HIGH-SPEED AEROPLANES" was the title of a talk given by "Mike" Lithgow at a recent meeting of the Leamington and Warwick Engineering Society. In this group are (I. to r.) Mr. D. F.
