1,081,236. Self-supporting cables. INTERNATIONAL STANDARD ELECTRIC CORPORATION. April 22, 1966. [April 27, 1965], No. 17688/66. Heading H1A. A fine grained powder containing particles in the range 0À01 Á to 10Á is applied or deposited on the support strand of a self-supporting cable prior to the extrusion over the support strand of a thermoplastic sheath. Tension between the strand and its sheath is thus increased and relative movement between them prevented. The powder used may be amorphous silicon dioxide or amorphous titanium dioxide produced by pyrolysis. |
