Abstract: A re-enterable cable jointing connector for electrical power distribution network cables and the method of using the connector to isolate cables physically and chemically one from another, the connector having at least two current carrying elements, each having at least three connection portions to which the individual cable cores may be attached, and having an electrically insulating body. The insulating body substantially surrounds the current carrying elements and extends at least up to the connection portions, thereby electrically insulating the current carrying elements from one another and interfacially isolating the cables from one another. Cables which are size, configuration or material incompatible may be jointed. Power cables may be optionally provided with in-line joints, branch joints or service connections by means of this compact connector.

Abstract: A connector device comprises first and second layers of substantially cross-linkable material, the first layer having inserts in contact therewith, the second layer having been expanded and thereafter formed into working and bonding zones, and the sheets being bonded together at the bonding zones for acceptance of substrates to be connected.

Abstract: A temperature increase or excursion sensor and locator consisting of a temperature sensitive cable which includes three electrical conductors, two conductors are separated by a dielectric member to form a linear strip capacitor and one of the two conductors has a number of thermostatic devices connected serially. Over or under temperature excursions are sensed and located by the cable when it is connected to control electronics by detecting the continuity and by measuring the capacitance of the cable. Under normal conditions, all of the thermostatic devices are electrically conducting and the control electronics measures the full capacitance from both ends of the cable and detects continuity over the full length of the cable. Upon a temperature increase or an excursion, one or more thermostatic devices become non-conductive, creating a discontinuity in one of the conductors and in addition the resulting capacitance is proportionately reduced.

Abstract: The invention is an over-temperature sensor and locator utilizing a temperature sensitive cable comprising (1) an electrical conductor, (2) a dielectric, and (3) a solid, conductive polymeric, positive temperature coefficient of resistance composition. An over-temperature condition at any point along the cable is detected by a drop in the capacitance of the cable, as measured from one end of the cable. The location of the over-temperature point on the cable is determined by comparing the reduced capacitance from the control end to the over-temperature point with the capacitance of the full cable length.
