Beacons For Antarctica AIRCRAFT accompanying two forthcoming Antarctic expedi-• tions will be guided by Redifon radio beacons. The Hunting Aerosurveys group, now on its way to Grahamland, will operatea Redifon G.40, and the Commonwealth trans-Antarctic expedition will use two Redifon T. 1918s. The standard G.40 supplied to the Hunting party has an outputof 500-750 W and will operate on C.W., M.C.W. and telephony. It is to be installed on Deception Island and will assist the twoCanso photographic aircraft undertaking the survey flights. Apart Mr. A. W.

The T.1918 was first shown in publicat this year's S.B.A.C. Exhibition. Anglo-American Hose iT is announced that a new Anglo-American company, PowerAuxiliaries, Ltd., has been formed for the production of seam- less flexible metal hose for aircraft and fighting vehicles. Knownas "Plessiflex," it is designed to withstand, over long periods, the high temperature and pressures associated with modern power-plants. The life of the hose couplings, also, is stated to be con- siderably in excess of present periods. Power Auxiliaries, Ltd., is a joint company formed by thePlessey Co., Ltd., and the DK Mfg. Co. of Chicago. The hose is produced to material specifications of the DK Co., and to prov-ing specifications of the Plessey Co., for the whole assembly. The interior construction of "Plessiflex" is shown in the accom-panying illustration. Materials generally employed are stainless steel, brass and bronze, but experiments are about to beginwith titanium. Cross - section of "Plessitlex" hose— a continuous cir- cular metal coil formed in seamless metal tubing and covered by double braiding. The hose assemblies have been subjected to rigorous tests by one of a well known British aero engine manufacturer and, as a result, a limited size-range has been approved for production release. Tests continue on the remaining sizes and it is hoped that a complete range of "Plessiflex" for aero engine installations will shortly be available.
