  • Patent number: 4722471
    Abstract: This invention relates to heat-shrinkable devices for forming solder connections between two bodies such as electrical conductors or pipes. The devices each comprise a hollow, heat-shrinkable sleeve having at least one aperture and containing first and second solder inserts. The solder inserts are located adjacent to each other and the second insert responds to heat applied to the device more slowly than the first insert. Usually the second insert has a higher melting point than the first insert. When the device is installed the first solder insert melts but is prevented from flowing out of the aperture in the device by the second insert. Also flow of the fused first solder insert onto the second solder insert causes the second insert to melt with less heat being applied to the device than would be needed if only the second, higher melting point solder insert were present in the device.

  • Patent number: 4713870
    Abstract: Disclosed is a pipe repair sleeve apparatus. There is a draw means having expanding means on either end of the draw means. There is also an annular repair sleeve. The draw means is contained within the sleeve with at least a portion of each of the expanding means protruding outside of the sleeve. Then, the repair sleeve assembly is inserted within the damaged pipe. The draw means urges the expanding means toward one another and inwardly of the sleeve so that opposed ends of the sleeve are expanded outwardly into engagement with an inside diameter of the damaged pipe. Preferably, the draw means is made from a material which is a shape memory alloy. Also disclosed is a method of repairing a damaged pipe. This method specifies the steps necessary for installing the pipe repair sleeve apparatus.

  • Patent number: 4705205
    Abstract: A chip carrier mounting device which is hereinafter also referred to as an "interconnection preform placement device" includes a retaining member having a predetermined pattern of apertures in which are positioned preforms of joint-forming material such as solder. The preform retains its general configuration after the interconnection or soldering process to form a resilient joint which is more capable of withstanding stress, strain and fatique. A method of forming resilient interconnections comprises placing the interconnection retaining member device between parallel patterns of electrically conductive elements, such as the conductive pads on an electronic component and a circuit board, and effecting the bonding of the conductive elements with the preforms. The joint-forming material may be a filled solder composition or a supported solder which substantially maintain their physical shape when the solder is molten, or a conductive elastomer.

  • Patent number: 4695676
    Abstract: This invention relates to an assembly of a splice between a cable containing paper insulation and a cable containing oil or petroleum based materials wherein the splice, or at least the end of the cable containing the oil or petroleum based material, is encapsulated in a particulate material such as calcium carbonate and placed under compression in order to prevent the oil or petroleum based material in one cable from migrating into the splice area or into the other cable and damaging the paper insulation in the splice or the other cable. The assembly also prevents the migration of water from either cable into the splice area.

  • Patent number: 4686327
    Abstract: A splice between two multiconductor cables is protected from ingress of water by a closure which contains a pressure means such as a bladder inside the closure capable of pressurizing a sealant present inside the closure to a pressure sufficient to force the sealant into the interstices of the splice and the interstices between the conductors in the cable, and maintaining the pressure until the sealant cures or hardens. The pressure means may also interact with seals at the end of the closure to seal the closure to the cable jacket.

  • Patent number: 4685683
    Abstract: A seal between an object such as a cable, cable splice or branch-off, and a surface such as a recoverable sleeve by means of a flexible envelope containing a void-filling composition. The void-filling composition undergoes a change from a low viscosity on installation, which allows the flexible envelope to conform to the object, to a high viscosity after installation, which gives mechanical strength to the seal. Deformation of the flexible envelope on installation may be brought about by installation of the recoverable sleeve or other surrounding surface.
