  • Patent number: 4451013
    Abstract: A cable reel adapted for use with telephone cable, at least one end of which has been "pre-connectorized." The reel has first and second spaced apart upstanding flanges attached one to another by a cylindrically shaped cross member. Inside of the cross member is a cable terminating receiving means adapted to receive an end or terminal portion of a telephone cable that has been "pre-connectorized." An aperture in the cross member aligned with cable terminating receiving means permits access thereto.

  • Patent number: 4426230
    Abstract: Disclosed are telephone cable filling materials and telephone cables comprised of a plurality of insulated electrical conductors twisted together to form a core in which there are a multiplicity of interstices between the insulated electrical conductors filled with the cable filler materials. The filling materials are composed of a petrolatum base material and inorganic microspheres and can be divided into two groups: (1) a first group to fill cables used at temperatures below the melting point of the petrolatum and (2) a second group to fill cables that may be used above that temperature. The first group is composed of mixtures of 40 to 90 weight percent petrolatum and 1 to 60 weight percent inorganic hollow (air filled) microspheres. When mixtures from this group are used as a filler in a telephone cable, the filler has a drip point nearly equal to the average melting point of the petrolatum, normally 57.2.degree. C. The second group is composed of two embodiments.

  • Patent number: 4351913
    Abstract: Disclosed are materials used to fill electrical and light waveguides transmitting communications cables to make them waterproof. The filling materials have superior waterproofing, dielectric and handling characteristics and are made from compounds of styrene-ethylene-butylene-styrene, styrene-butadiene-styrene or styrene-isoprene-styrene type block copolymers dissolved in paraffinic or naphthenic type mineral oils with a minimal content of aromatic hydrocarbons, inorganic hollow microspheres and, if desired, an additive such as low molecular weight polyethylene or glycerol hydroxy stearate.

  • Patent number: 4340771
    Abstract: An improved internally screened cable is disclosed that not only provides efficient shielding to meet near-end cross-talk requirements in present day and anticipated future carrier systems, but also armor protection as well, both the shielding and armor protection arising out of a single metallic shielding tape composed of two layers of aluminum or copper metallurgically bonded to both surfaces of an iron or steel layer. The tape is corrugated and has a medial portion integrally joined to two terminal portions. The cable core is composed of two groups of conductors divided and shielded one from the other by the medial portion of the shielding tape. Terminal portions of the shield are bent in opposite directions and lie on the periphery of the groups of the core and extend to and beyond that point where the medial and terminal portions merge.
