Abstract

437,293. Cables. STANDARD TELEPHONES & CABLES, Ltd., and HUGHES, R. L., 63, Aldwych, London. April 27, 1934, No. 12747. [Class 36] In a communication cable of the concentric return type, the return conductor is made of lead or lead alloy and has an internal diameter 5 to 5À6 times as great as the external diameter of the copper central conductor. The conductors may be spaced apart by washers or beads to provide air-space insulation, or the central conductor 1 may be wrapped with alternate layers 2, 3 of paper and string over which the lead return conductor 4 is extruded. The cable, when used for submarine purposes, may have armouring, consisting of wires 6 embedded in tarred jute 5, applied over the return conductor 4.
