Abstract: An electrical cable of conventional or retractable helical coil form which is relatively small in diameter and sufficiently flexible to be used to advantage on a tractor-trailer to connect the power supply on the tractor with the electrical system carried by the trailer has a polymeric sheath, an insulated 10 gauge stranded conductor substantially coaxial with the sheath, four to six insulated stranded 12 gauge conductors substantially evenly spaced about the periphery of the 10 gauge conductor, a plurality of uninsulated stranded conductors of 14 gauge disposed between the smaller insulated conductors, filler material filling the spaces between the conductors and preferably a plastic film helically wound about the conductors. The 12 and 14 gauge conductors are helically wound about the 10 gauge conductor. The assembly of conductors, filler and plastic film combine to form a cable having a substantially circular cross-section and substantially fill the sheath.

Abstract: The present invention relates to methods for processing curable thermoplastic elastomers and particularly to flexible, shaped articles made therefrom which have improved high strength, radiation and temperature resistance and electrical characteristics useful as fluid transmission tubing and/or as electrical insulation. Such articles are made from uncured, thermoplastic elastomer materials -- in the form of selectively hard, radiation sensitive, flowable solids -- which are thermoplastically molded to provide an essentially uncured, dimensionally stable, intermediate shaped article. Such intermediate articles are radiation-cured to provide finished cross-linked articles having such characteristics.

Abstract: A dimensionally stable, flexible, hydraulic hose having an elastomeric core tube cross-linked by irradiation with ionizing electrons, a fibrous reinforcing layer surrounding the core tube which prevents the core tube from expanding with increase in pressure and a protective elastomeric sheath about the reinforced core tube.

Abstract: A self-retracting flexible composite hose of helical configuration has a core tube and sheath of crystalline-like polymer which has an elastic memory, a layer of helically wound spaced strands of fibrous reinforcing material which only partially covers the core tube and polymeric protuberances integral with the sheath extending between the strands and fusion welded to the core tube.
