  • Patent number: 5426715
    Abstract: The invention provides for a cold applied oval port seal particularly useful for sealing optical fiber cables. The closure includes two shell members which fit together to define the enclosure edge wedge seals and internal flexible fingers to locate the optical fibers, restrain movement of the sealing material, and provide strain relief along the longitudinal axis of the cables.

  • Patent number: 5201672
    Abstract: An apparatus for protecting a substrate includes a collapsible reservoir filled with a three-dimensional elastic gel which is relatively soft and has an ultimate elongation of at elast 200%. The apparatus is disposed in contact with a substrate having a recess therein to be environmentally protected, and a force is applied to the reservoir to at least partially collapse the reservoir forcing the gel from an open surface of the reservoir into the recess so as to substantially fill and encapsulate the recess.

  • Patent number: 4769513
    Abstract: There is disclosed a cable closure which includes a central closure body and a pair of end caps preferably made from structural foam situated at each end of the closure body. There is also disclosed a cable block which includes void filling material selectively inserted among the insulated conductors of the cable and a directional control device which consists of a conduit also selectively inserted among the insulated conductors of the cable. Together the cable closure, cable block and directional control device make up the splice closure system. There may also be provided a heat recoverable seal adhesively attached to the cable closure in which case there will also be provided means for preventing milk-off of the seal from the cable closure. finally, there is disclosed a method for forming the cable block.

  • Patent number: 4692565
    Abstract: A closure which consists of a closure body having two segmented end seals. Each of these segmented end seals consists of a support structure and at least two pie-shaped end sections. The end sections are sized and configured for mating with the support structure. Each of the end sections has a portion of its periphery which comprises a segment of the periphery of the assembled segmented end seal so that when the end sections and the support structure are mated together the assembled segmented end seal has a uniform periphery. At least one of the pie-shaped end sections contains an aperture for receiving a cable wherein the aperture is located entirely within the periphery of the section.
