Applying Superposed Coatings Or Coating A Coated Base Patents (Class 427/118)
  • Patent number: 3971884
    Abstract: Crosslinkable ethylene-vinyl acetate copolymer resins are rendered amenable to forming adherent laminates with crosslinkable silicone rubber by coating the surface of the ethylene-vinyl acetate resin with a solution of a silane or a member of the class of compounds known as polyfunctional monomers prior to adhering the resin to the silicone rubber.

  • Patent number: 3962517
    Abstract: A cable core and method of forming such core is provided including a conductor having an extruded dielectric of an insulating material selected from the group of insulating materials consisting of rubber and plastics materials, a dielectric screen comprising a layer of conductive or semi-conductive material selected from the group consisting of conductive and semi-conductive rubber and plastics materials and, interposed between and bonded to the extruded dielectric and the dielectric screen throughout substantially the whole length of the core, an intermediate layer having at least in a circumferentially continuous zone of the layer a cohesive strength substantially less than the cohesive strengths of the extruded dielectric and the dielectric screen and substantially less than the strengths of the bonds between the intermediate layer and the dielectric screen such that when stripping the dielectric screen from the core over a part of its length for jointing or terminating purposes separation takes place with

  • Patent number: 3935042
    Abstract: A method of manufacturing high voltage carrying electric power cable having a conductor insulated with a multilayered covering, and the cable product thereof. The cable construction includes a primary or dielectric insulating body of thermoset ethylene-propylene rubber and a thermoset jacket about the conductor, which is substantially free of corona-prone or ionization-prone voids and separations intermediate the layers. The method comprises forming and curing the ethylene-propylene rubber compound constituting the body of the primary or dielectric insulation around the conductor and then heat treating the thermoset-cured ethylene-propylene rubber insulation prior to applying subsequent components of the multilayered covering about the condutor, including an overlying semiconductive shielding layer and a protective enclosing jacket of heat-cured thermoset polymer.
