    摘要: A plumb bob having a central body portion and at least three substantially identical webs extending outwardly from the body portion along respective radial axes. The angles separating each successive web must be equal to maintain vertical symmetry, and an even distribution of weight, with respect to a longitudinal axis extending centrally through the body portion. In addition, the webs uniformly and linearly taper in a decreasing manner from the top end to the bottom end of the body portion. This geometry permits a worker standing in vertically aligned position above the plumb bob to be able to clearly see both the bottom end of the plumb bob and the preexisting datum from which alignments are being made.

    摘要: An emergency device which is stowed into a compact enclosure attached to the lintel of an upper-story window to facilitate evacuation in case of fire. The device comprises a windlass upon which is coiled a sturdy web supporting a body harness. The unrolling of the web is restrained by a powerful brake mechanism which can be controllably released by means of a handle associated with the harness. The control cable which connects the handle to the brake mechanism is coiled alongside the web and is unrolled at the same pace; thus giving the user continuous hand control of the brake release during the whole descent.

    摘要: A implantable interference device configured for intra-facet placement within a facet joint is provided. The device includes a shank capable of engaging opposing faces of the facet joint. The shank can further include a head extending from a proximal end of the shank wherein the head is configured to engage and/or buttress opposing faces of the joint, and also configured for preventing over-insertion of the device. Optionally, at least a portion of the shank can include or be formed of a fusion-promoting bioactive material. Further, a method for providing fixation of a facet joint by intra-facet placement of an interference device within the facet joint is provided.
