  • Patent number: 9115777
    Abstract: A self-retracting extension limiting device. It is designed to be attached between a first object and a second object, where the distance between the first and second objects is variable. The device exerts a restoring force tending to draw the two objects together. A first, relatively weak restoring force is exerted over a range of distance. Then, when the objects have been separated to a defined limit of travel, the device exerts a much greater restoring force. The invention includes overlapping and self-contained elements so that unwanted slack is minimized.

  • Publication number: 20070108656
    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.

  • Publication number: 20070107927
    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.

  • Publication number: 20060160435
    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.
