Abstract: A coaxial cable connector is provided comprising an inner conductor, insulating material, outer conductor, and dielectric restrainer so molded polymeric material located in grooves selectively positioned between the inner conductor and insulating material and outer conductor and insulating material.

Abstract: This invention relates to porous polytetrafluoroethylene (hereinafter PTFE) materials having the property of rapid recovery and a method for producing these materials. The microstructure of the porous PTFE material consists of nodes interconnected by fibrils, substantially all of the fibrils having a bent or wavy appearance. Artricles made from these materials are particularly suitable for use in the medical field, but are also useful in other areas such as filtration and fabric applications.

Abstract: A security system comprising a signal-carrying member and a detector for detecting a change in the resistance of the conductive path surrounding a core of the signal-carrying member. The conductive path comprises inner and outer layers of semi-conductive tape separated by an insulating layer but interconnected at one end. The semi-conductive tape of at least the outer layer is made of fibrous material such as carbon-leaded PTFE such that when a sharp object pierces the outer layer and the insulating layer, semi-conductive fibers are dragged from the outer layer into contact with the inner layer and form a conductive bridge between the layers.

Abstract: A pipe bag is constructed from a flexible composite material which is airtight but readily permits the transmission of moisture vapor. At least one layer of the flexible composite material is a continuous hydrophilic layer. When a moisture vapor concentration gradient is present across said hydrophilic layer it transfers substantial amounts of water throug the layer by absorbing water on the side of the layer at which the higher water vapor concentration exists, and desorbing water on the opposite side of the layer at which the water vapor concentration is lower. As a result of this the moisture concentration within the bag is regulated.

Abstract: Apparatus and a method for testing leaks in the footwear articles are provided. Bootie and sock inserts for shoes made of waterproof materials in which the seams are seam-sealed have become popular among people who are involved in sports and other outdoor activities. Many of these products are sufficiently waterproof so that guarantees are made as to their waterproofness. A method for testing and apparatus for testing has been developed which can perform tests on multiple footwear articles simultaneously and produce immediate and reliable results within a matter of minutes. Footwear articles may include boootie inserts, socks, or shoes.

Abstract: The present invention relates to a prosthetic ligament comprising at least one intra-osseous bearing members in a bone of a joint and an intra-articular linkage means connecting the intra-osseous member to the other bone so that multiple degrees of motion are provided between the bones.

Abstract: This invention relates to connectors for cables with prearranged spacing configurations between signal conductors and ground conductors thus allowing use of higher density cables for high speed electronic signals. Ground conductors are attached to the housing of the connector.

Abstract: The present invention relates to single and twisted pair transmission line wires wherein the effective electrical diameter of the primary conductor is increased. This is accomplished by wrapping conductive foil or conductive foil laminated to a substrate layer onto a primary conductor with a diameter less than 20 mils wherein the foil is in contact with the conductor and has an outer insulating cover.This may be done by either spiral wrapping or by longitudinal wrapping around the electrical conductor. This invention provides a desired characteristic impedance along the length of the wire(s) and allows easy removal for standard termination and increased cut-through resistance.
