  • Patent number: 8236219
    Abstract: A process for forcibly infusing liquid potting compound into the strands of a cable in order to attach an anchor to the cable. The process uses a strand cavity within an anchor that encloses the exposed strands. The strand cavity is sealed. Liquid potting compound is then forced into the strand cavity, where it runs around and through the exposed strands. A second venting passage is preferably employed, so that the liquid potting compound flows through the mold without trapping any substantial air pockets.

  • Patent number: 8215886
    Abstract: A termination system which attaches a conventional threaded rod or bolt to a cable. An anchor is attached to an end of a cable using known techniques—such as potting. A threaded rod or bolt is placed on the anchor, pointing away from the direction of the cable. The rod or bolt is mechanically attached to the anchor using several different techniques. The result is an anchor assembly including a threaded protruding shaft. Because the assembly uses an inexpensive prior art rod or bolt, the machining operations are confined to small components needing relatively little material removal.

  • Patent number: 8048357
    Abstract: A process for forcibly infusing liquid potting compound into the exposed strands of a cable prior to forming a termination. The process uses a mold that encloses the exposed strands. Potting compound is then pumped into the mold, where it runs around and through the exposed strands. A second venting passage is preferably employed, so that the liquid potting compound flows through the mold without trapping any air pockets.

  • Patent number: 7818849
    Abstract: A termination anchor having a neck region, a mid region, and a distal region. An expanding passage through the anchor from the neck region to the distal region is bounded by an internal surface. Exposed strands on a cable are trapped within this expanding passage by infusing them with liquid potting compound (either before or after the strands are placed within the passage). This liquid potting compound solidifies while the strands are within the anchor to form a solidified potted region. The present invention optimizes the profile of the internal surface in order to transfer stress occurring in the neck region to the mid region and the distal region. By transferring some of this stress, a more uniform stress distribution and a lower peak stress are achieved.

  • Patent number: 7536754
    Abstract: A connecting system which allows a standard rigging fixture to be connected to a synthetic cable termination by swaging. The cable termination is provided with a swaging sleeve. When the standard rigging fixture is placed next to the termination, this swaging sleeve is swaged over a portion of the standard rigging fixture in order to lock the standard rigging fixture to the termination. The provision of the swaging sleeve on the termination is accomplished using a variety of approaches, including forming the swaging sleeve as part of an anchor, providing a separate swaging sleeve attached by threads, and forming the anchor and swaging sleeve with two separate swaging operations.
