312 FLIGHT. SEPTEMBER 23, 1937. NEWS from HERE and THERE A A Swash-plate Engine Design VERY unusual engine design emanating from an engi neer who has been " in the game " from the very beginning should be interesting. Assisting Maurice Farman in his early efforts and suffering in company with a few others the derision of cynics who saw no use in supercharg ing, Mr. J. Wooler has been responsible for several very successful engines, particularly for motor cycle racing. The aero engine design which he has lately produced, the result of spare-time work spread over the last year or so, embodies the swash-plate principle. It is radial in a sense and, as can be seen from the drawing, has horizontally opposed pistons The designer feels that the special ad vantage of such an engine is in the lightness of construction made possible by the fact that practically all the energy is conveyed in an even torque to the crankshaft, which also takes most of the strain usually placed on the crankcase and cylinder walls. The number of moving parts is small and the usual advantages of opposed pistons and single com bustion chamber should be secured. Such a design it is claimed, allows a very compact and light layout without the usual attendant efficiency losses and difficulty in accessibility and cooling. Full particulars and plans for development can be furnished by the designer, whose address is West End Road, South Ruislip, Middlesex. For Ex-R.F.C. Wireless Operators T HE Royal Flying Corps Wireless Operators Old Comrades Association, formed to foster the spirit of comradeship created during the war, has been in existence since 1930. Mem bership is open to all wireless operators who served in the R.F.C. and R.A.F. up to 1919. Reunions are held on the second Tuesday in each month and visits to various places of interest are arranged. The annual dinner is to be held on Saturday, October 30, at the First Avenue Hotel, High Holborn, London, W.C.2. Full particulars can be obtained from the Hon. Secretary, 56, Regency Street, London, S.W.i. Plastic Progress OWING to the enormously increased demand by the aircraft industry for the kind of work (windscreen moulding, etc.) in which they specialise, Plastilume Products are now doubling the area of their factory by taking over the premises adjoining their present factory in Humes Avenue, Boston Road, Hanwell, London, W.7. This is the second extension by this firm within the last twelve month.';. Mr. R. H. Moon has recently joined the organisation, after having been chief salesman of the Celastoid department of British Celanese, Ltd., for the last few years. The layout of the Wooler swash-plate engine, dealt with on this page. Safe Anchorage A RATHER novel type of screw picket, termed the -"-"*- " Scrulix " guv anchor, .is being supplied to the Air Ministry, Admiralty and War Office, and is being used for picketing aircraft, anchoring temporary hangars, and many oiher purposes. It is very simple in construction, consisting merely of a steel rod with an eye at its upper end and a sharp and sturdy helix at the other. It is screwed into the ground by means of a bar through the eye. In ordinary earth it is stated, a 5ft. " Scrulix " anchor The Scrulix picket, showing the helix. with 5m. diameter helix will withstand a pull of 11,200 lb. A wide range for loads of from 1,120 lb. to 40,000 lb. is offered, including a special aircraft model of low weight. The makers are The "Scrulix" Co., Ltd., 36-38, Victoria Street, London. For Screens and Windows WELL established during recent years in the manufacture of airciaft windows, cockpit enclosures and inspection panels, Rhodoid " V.4 " transparent sheeting now gives place to a further improved product by the same makers, May and Baker, Ltd. Known as " V.7 Aviation Rhodoid," this sheeting not only has enhanced clarity, greater resistance to scratching and a higher degree of polish, but will, it is stated, remain stable in quality up to the highest temperatures likely to be used in moulding or bending. The new "V.7" quality retains the toughness and high impact strength characteristics of cellulose acetate sheet, and is available in a range of thicknesses from 1 mm. for inspection panels up to 6 mm. for windows and screens of high-speed machines, whilst complying with the requirements of B.S.S. F.56 in all thicknesses. Revised information regarding the most satisfactory methods of working and forming Rhodoid is now available on request to May and Baker, Ltd., 42/3, St. Paul's Churchyard, London, E.C.4. Intense THE concentrated coiled-coil filaments of the newest G.E.C. projector lamps operate at a temperature above that of the oxy-acetylene flame, and higher than the boiling point of iron. Certain types of these lamps play their part in aero drome lighting equipment.
