  • Patent number: 7228626
    Abstract: A mandrel, useful in high voltage cable splicing and termination operations, having a tapered surface and longitudinal ribs for assembly onto a high-voltage cable to be connected to a premolded or extruded high-voltage component. As the premolded high-voltage component is passed over the mandrel, the mandrel expands the internal cavity of the high-voltage component and may further reduce the loss of lubrication within the internal cavity of the high-voltage component thereby allowing for the high voltage component to be easily installed onto the high-voltage cable. After the high voltage component passes over the apparatus, the high-voltage component may return to a lesser-expanded shape providing a snug fit around the cable member. The high-voltage component may then compress around the cable, with a uniform layer of lubricant remaining in between interior cavity of the high-voltage component and the outer layer of the cable.

  • Patent number: 6022054
    Abstract: A pipe coupling for two pipe ends having the same inner diameter includes a first pipe coupling joining the pipe ends. The first pipe coupling is formed from a section of pipe having approximately the same inner diameter as the pipe ends and is split longitudinally. A second pipe coupling is clamped over the location of the junction between the pipe ends. The second pipe coupling is formed from a section of pipe having approximately the same inner diameter as the pipe ends and is split longitudinally. The split of the second pipe coupling is offset from the split of the first pipe coupling. The couplings may include an inner and an outer coupling, two outer couplings, or an inner coupling and two outer couplings. Each inner coupling have a strip of material removed along its longitudinal split so that it can be compressed to substantially close the gap at its split and inserted into a pipe end.

  • Patent number: 6000436
    Abstract: Multilayer fluid conduits are formed by adhering to a tubular outer surface of a metal pipe, a thermoplastic outer layer. The outer layer permits ends of the multilayer conduit to be joined together in leak-proof fluid conduit systems simply by adhering the conduit ends with compatible thermoplastic fittings. For fire protection systems, the preferred metal is steel, the preferred thermoplastic is CPVC and the preferred adhesive is heat activated. The adhesive coated metal pipe is preheated and the CPVC is extruded onto the outer surface of the heated metal pipe. Through the use of fire resistive CPVC, the multilayer conduit systems of the present invention can be installed in more severe fire threat areas than can existing, all plastic piping, including all CPVC piping systems. The conduit is assembled into systems on site simply by cutting and direct bonding with ordinary, all plastic fittings using appropriate bonding agents such as solvent based adhesives.

  • Patent number: 5899235
    Abstract: A ferrule includes a tubular wall and end wall which is divided into radially extending fingers, each of which terminates at a barb member formed by deflecting a tapered end portion of the finger. The end wall fingers extend orthogonally to the longitudinal axis of the tubular wall and the barb members are each inclined at an acute angle to the carrying fingers and axis such that when a tubular body, such as a braided or like textile sleeve, is received in the tubular wall and the end all is swaged to cause the fingers to enter the body and lie flat against the tubular wall, the bars are caused to penetrate the body and be flattened by the tubular wall to point in the direction towards the body end and inhibit its removal. The tubular wall may be circumferentially continuous (annular) or discontinuous (slit) and openable.
