Abstract

1,057,888. Slip-ring construction. SPERRY GYROSCOPE CO. Ltd. Oct. 18, 1963 [Oct. 23, 1962], No. 40079/62. Heading H2E. A method of forming an assembly of concentric ring-shaped contacts separated by insulating rings for use as a slip-ring or a jack-plug comprises forming, successive layers of insulation, each layer being stepped back at at least one edge from the preceding layer, and the layers carrying conductive bands on to which metal may be deposited by electrolysis to form the contact rings. In the first embodiment, Fig. 1, the insulating material is a thin sheet 2, of polyethylene terephthalate, slightly tapering in shape, and carrying L-shaped conducting strips 4, 5, 6, 7 and 8, formed as described in Specification 1,003,575. The strip is wound on to a stainless steel core 1, so the edges lie in spirals forming the successive steps. The ends of the limbs 9, 10, 11 and 12 of the conducting strips are exposed at the lower edges of the spiral enabling electrical connections to be made to the metallic bands 4, 5, 6 and 7 respectively. The assembly is immersed in an electro-plating bath and rings are built up on the bands 4, 5, 6 and 7 as shown at 14. 15, 16 and 17 (Fig. 3). Tool 19 is used to true up the rings facing in the direction of the axis of the core. The assembly is encapsulated in a suitable plastics material, e.g. an epoxy resin, and then trued up along the dotted line III in a lathe. In the second embodiment, Fig. 7, a layer of insulating material 20 is polymerized on to core 1 and the end is masked by a composition 31 readily soluble in a solvent which does not dissolve the polymerized layer 20. The layer 10 is treated with a catalyst solution as described in Specification 1,003,575, and a metallic layer deposited thereon. A further layer of insulating material is polymerized to the metal layer stepped back a little from the end, and the process is continued. The metal steps 25, 30, 35, are used as bases for the buildup of contact rings as in the first embodiment. In a third embodiment, which is similar to the first embodiment, a differently shaped sheet of insulator is initially used.
