  • Synthetic latex modified pulp insulated conductors
    Patent number: 4256807
    Abstract: A pulp insulated electric communications conductor in which the wood pulp fibers of the insulation are coated with an aqueous based cationic deposition aid polymer and then an aqueous based anionic latex polymer. In a process for applying a layer of insulating material to the conductor a slurry of wood pulp fibers is prepared to which first an aqueous based cationic deposition aid polymer is added and then an aqueous based anionic latex polymer is added, the resultant coated wood pulp fibers being applied to the conductor.
    Type: Grant
    Filed: August 23, 1979
    Date of Patent: March 17, 1981
    Assignee: Northern Telecom Limited
    Inventors: John A. Jukes, Thomas C. Pound, Wayne A. Cascarano
  • Paper pulp insulated cable and method of manufacture
    Patent number: 4218580
    Abstract: A paper pulp insulated cable of the kind having a plurality of conductors covered with paper pulp insulation. The insulated conductors are twisted into pairs, the pairs are stranded into units and the units are built up into cores, covered with, for example, a paper wrap, aluminum, steel sheath and a polyethylene jacket. The cable has a high density of conductors. Also a method of manufacturing such cables is described.
