Abstract

887,063. Making waveguides; coiling. STANDARD TELEPHONES & CABLES Ltd. March 7, 1958 [March 8, 1957], No. 7745/57. Classes 83 (2) and 83 (4). [Also in Group XL (b)] A circular wave guide is made by coiling wire on a cylindrical mandrel and securing adjacent turns of the coil together with adhesive. A second wire may be wound on to the first coil to lie in the grooves between its adjacent turns. Wire 32, Fig. 8, is wound on a rotated cylindrical mandrel 31, the thus wound coil 33 being pushed there-along and over a tapered end thereof by rollers 37 mounted on fixed axes. A second wire 34 of a slightly smaller diameter than the wire 32 is led through a bath 35 of molten resin and laid in the grooves between the turns of the inner coil 33 to form an outer coil 36. The mandrel 31 is electrically heated, current being supplied through a slip ring 39. The formed waveguide 41 is supported after leaving the mandrel 31 by rollers 43 driven a slightly greater peripheral speed than the waveguide, an idler roller 42 and pairs of idler rollers 49. The waveguide may be wrapped with tape or thermoplastic material may be extruded thereover. The outer winding could be of fibre glass. Insulating material may be applied to the outer surface of the outer winding. The wire may be bare or insulated by anodization or coating with shellac. The adhesive may be applied by a brush or spray as the wire is being wound. A fixed peg 5, Fig. 4, may push the coiled wire along a mandrel 3 which has an outer part of lesser diameter to reduce friction. A completed coil 25, Fig. 6, may be supported after leaving a mandrel 18 by a plug. 23 keyed on an extension 20 of the rotating mandrel and engaging the end of the coil. According to the Provisional Specification the wire may be coated with polyethylene and heat applied by a heated pad. Copper wire coated with solder may be used. Adhesive may be set by a gas flame. The outer coil may be of polyvinylchloride. A flange on the mandrel or on an idler parallel to the mandrel may push the wound wire there-along.
