Abstract

842,479. Cables. MONETCATINI SOC. GENERALE PER L'INDUSTRIA MINERARIA E.CHIMICA. Nov. 1, 1957 [Nov. 6, 1956], No. 34170/57. Addition to 810,023. Class 36. Conductors are insulated with highly crystalline polybutene or mixture thereof with highly crystalline polypropylene. The insulation may be applied by extrusion, the conductor travelling at such a rate that the insulation is stretched, by passing the conductor through a bath of the molten composition or by winding on tapes. An outer' protective coating of polypropylene, polyamide resins, vinyl polymers in copolymers or textile materials may be provided with or without wire armouring. Specifications 828,791, 834,554, and 835,330 also are referred to.
