Abstract
1301992 Making flexible waveguides KABELUND METALLWERKE GUTEHOFFNUNGSHUTTE AG 19 April 1971 [17 March 1970] 24240/71 Heading H1W A flexible waveguide of circular (as shown), or any other cross-section, is formed by bending a metal strip 1 about its longitudinal axis, welding together the edges of upturned portions 4 and bending-over these portions against the outer surface of the resultant tube. The tube is then provided with an inner coat 2 of thermoplastic polymer, e.g. polyethylene, and an outer coat 3 of a synthetic resin, e.g. a copolymer of ethylene and other monomers. The tube 1 may be made of copper or aluminium. The weld is gas-tight and is made by means of a gas-shielded arc. The seam may provide a guide for the direction of polarization of the transmitted wave.
