  • Patent number: 5721664
    Abstract: A surge arrester designed for use with lines of 2 kV or less has a housing (10) which, in combination with a cup-shaped gasket (25), an O-ring gasket (45) and a lid (20), seals a varistor element (30) inside against environmental contaminants such as water or pollutants.

  • Patent number: 5583734
    Abstract: A surge arrester for protecting power distribution equipment from overvoltages has a varistor as the active surge-arresting element. In the event of a persistent overvoltage, an amorphous conductor electrically in series with the varistor heats up to or above a critical temperature at which its tensile strength substantially decreases. The amorphous metal conductor breaks, triggering a series of events including the closing of a switch creating a permanent short to ground, operating the network overcurrent protection to de-energize the arrester and associated protected equipment, and protecting the electrical network equipment from insulation damage and/or failure because of a sustained or permanent power frequency overvoltage condition.

  • Patent number: 5415065
    Abstract: A hand tool formed by a body member 10B and a torque sleeve member 12S is employed to tighten a connector nut 14N at the end of an electrical cable 14C onto a cable terminal post 14P. The body is elongated having a long axis with a socket wrench 10W at one end and a handle 10H at the other end. A cable channel 10C extends along the long axis from the wrench end to the handle end for receiving the cable during installation. The inside surface of the wrench has side walls 10SW for capturing the connector nut. The outside surface of the wrench has a slight taper toward the wrench end of the body, and the inside surface of the sleeve has a generally matching taper. The sleeve is slide mounted over the wrench and the connector nut for establishing a pre-load hoop tension in the sleeve against the wrench which establishes a pre-load compression in the wrench against the connector nut. The engagement of the matching tapered surfaces causes the pre-load hoop tension to increase as the sleeve is slid over the wrench.

  • Patent number: 5286952
    Abstract: Articles including a thin laminar heating element composed of a sintered conductive polymer, and electrodes attached to the heating element so that current flows in the plane of the element. The article can be placed between and in contact with two substrates, and then heated to join the two substrates together. Preferably at least one of the substrates is polymeric and becomes melt-fused to the article.

  • Patent number: 5111025
    Abstract: A flexible heater in which a heating element in the form of a tape is wrapped around a support member in the form of a flat sheet. The tape, which exhibits flexibility and toughness, has a composition composed of conductive sintered ultrahigh molecular weight polyethylene. The flexible heater is suitable for heating an upholstered seat, e.g. an automobile seat.

  • Patent number: 4674818
    Abstract: A hollow, cylindrically shaped, elastically deformable sealant member is disposed over external threads of a mounting unit, and subsequently a driver element having internal threads matable with the external threads is screwed onto the external threads, an elasticity and inside diameter of the sealant member being such so as to tightly adhere to at least one turn of the external threads and an outer surface of the driver element to provide an environmental seal between the internal and external threads.

  • Patent number: 4655159
    Abstract: A compression pressure indicator includes a compression member which is disposed within a termination and is constructed such that when exposed to a pressure above a predetermined pressure a portion of the compression member protrudes from the termination thus indicating that optimum pressure has been applied inside the termination. The compression member includes an indicator portion and a collapsible portion, the collapsible portion being shaped such that when exposed to a pressure above the predetermined pressure, the collapsible portion collapses thus allowing relative movement between the indicator portion and pressure extending member such that the indicator portion protrudes a predetermined distance from an end of the pressure exerting member.

  • Patent number: 4650228
    Abstract: A heat recoverable coupling assembly for substrates having a relatively rigid outer wall, which includes a connector body and a driver member made from a band of heat recoverable material. The connector body includes a mating area for engaging a mating area on the rigid wall of the substrate. The connector body is positioned inside or outside the substrate and the driver member is positioned around the outside member. The driver member has an unrecovered transverse dimension larger than the outside member and a recovered transverse dimension smaller than the outside member. The driver member is positioned around the outside member over at least part of the mating areas. Upon heating the driver member to its recovery temperature, the driver member deforms the outside member and itself plastically deforms to a shape suitable for retaining the substrate and the connector body together. The driver member is made from heat recoverable engineering plastics.

  • Patent number: 4639068
    Abstract: A holder for holding a coupling assembly useful for terminating a CATV coaxial cable includes first and second parallel, longitudinal grooves capable of retaining a plurality of connector bodies and driver members for facilitating assembly to a stripped coaxial cable end.

  • Patent number: 4583811
    Abstract: A coupling assembly and a method of connecting and terminating coaxial cable is disclosed herein. The coupling assembly includes a connector body having a mating area for the cable, a driver, means for urging the driver and the body toward each other, a compressive member positioned between the connector body and driver which is deformable and which has sufficient compressive strength to deform the cable jacket. When the compressive member is deformed by the driver the compressive force from the member is focused by the connector body to deform the cable at the mating area and to provide an environmental seal and EMI seat between the cable and coupling assembly.

  • Patent number: 4570055
    Abstract: An electrically heat-recoverable assembly comprising a heat-recoverable article and a pair of electrodes. The electrodes supply current to the article without interferring or limiting the way in which the article can be deformed in order to render it heat recoverable. The electrodes are placed and connected to the article in light of the properties of the article, especially its volume resistivity. The assembly significantly reduces the possibilities of arching or sparking while generating sufficient heat that is generated sufficiently uniformly throughout the article.
