  • Patent number: 4382821
    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: 4381772
    Abstract: An improved contraceptive diaphragm is provided which has a bioerodible matrix that disintegrates in the vaginal fluids within a predetermined period of time. The matrix is made from a water soluble gel, more particularly from a water soluble polymeric resin gel, and preferably from a polyvinyl alcohol resin gel. The solubility of the water soluble gel in the vaginal fluids is controllably reduced for example, by heat treatment of the gel after formation of the diaphragm. The diaphragm does not have to be removed in a single piece, but is excreted as a slight vaginal discharge. In one aspect of the invention, a natural collagenous protein is embedded in the matrix to assure sealing adherence of the diaphragm when positioned in the vagina. In another aspect of the invention a hydrophilic material is provided at the center of the matrix to effectively absorb secreted cervical mucus thereby creating a dry passageway which will impede entrance of the sperm.
