732 FLIGHT, 5 June 1953 THE INDUSTRY Power Jets Appointment TT is announced that Mr. T. G. Hicks, M.A., C.P.A., has been * appointed joint managing director of Power Jets (Research and Development), Ltd. Mr. Hicks was educated at Bradfkld College and at Trinity College, Cambridge (where he read Natural Sciences), qualified as a patent agent in 1933, and was engaged in private practice until the war. He then served in the Technical Branch of the R.A.F.V.R. and in 1946 joined the Patents Branch of the Ministry of Supply, being detached to work at the Royal Aircraft Estab lishment, Farnborough. He joined Power Jets in May 1950. Rumbolds Celebrate pORONATION celebrations by L. A. Rumbold and Co. Ltd., ^-/ took place recently at the Cumberland Hotel, London, when Mr. and Mrs. Rumbold welcomed 121 guests drawn from the aircraft industry, airlines, charter companies, the Royal Aero Club and senior members of the firm's own staff. Stress was laid on the business in hand—enjoyment of the evening to the full—and speeches were short almost to the point of extinction. R. S. Stafford, chief designer to Handley Page, Ltd., did note in passing that for his firm alone, Rumbolds had been responsible for the interior furnishing of 1,590 Halifaxes, 150 Hastings and 29 Hermes. Means to an End "CND-FITTINGS designed for attachment to rigid tubing by *•* mechanical means with suitable hand tools, and without the need for brazing, welding or flaring operations, are a recent devel opment by Avica Equipment, Ltd., 1 Adams Place, Georges Road, London, N.7. Coupling parts can be made in non-stabilized stainless steel, cadmium-plated mild steel, anodised aluminium, or titanium. It is claimed that extremes of temperature and vibration have no effect upon this design of leak-proof fitting, while any fluids, gases and corrosive agents can be handled provided the appropriate material is selected for both tube and fittings. Aluminium fittings can be attached to aluminium tubing by this method without the application of heat or excessive working of the tube; for example, light-alloy fittings may be attached to light-alloy tubing, or, for higher pressures, Tungum fittings to Tungum tubing. Similarly, stainless-steel tubing can be expanded into Avica stainless-steel fittings, thereby eliminating any changes in the characteristics of the metal, or tendencies to corrosion or weld- decay, as might occur in welding or brazing operations. Briefly, the process of attachment is as follows : the tube is gripped in the correct size of Avica tube-holding block, in a vice, and the end trimmed square and cleanly finished inside and out; the appropriate size of end-fitting ferrule (together with a swivel flange, if required) is then slid over the tube until the latter butts against a stop flange within the ferrule; and an expander tool— a taper mandrel provided with rollers in its working face—is then inserted in the tube-end. Turning the mandrel in a clockwise direction has the effect of expanding and swaging the tube into three annular grooves in the bore of the ferrule. The fittings can be salvaged for re-use by removing the tubing from the fitting by a suitable method—e.g., turning in a lathe. IN BRIEF From June 22nd to 26th a residential short course on manage ment accounting will be held at the College of Aeronautics, Cranfield. •* • * C. C.
