  • Patent number: 5655741
    Abstract: A pivotal apparatus for supporting instruments beneath a patient during certain diagnostic procedures. The apparatus is adapted for pivotal locking engagement in a support member having at least one extensible and retractable mounting pin and includes an elongated shaft, a tray supported by the shaft, a latch mounted on one end of the shaft and a slide release disposed about and axially translatable along the shaft toward the latch. The mounting pin extends in a partial circumferential slot between the latch and the slide release when the apparatus is engaged in the support member whereby the apparatus pivots through a predetermined degree of rotation relative to the support member as the mounting pin travels in the slot. The apparatus is disengaged from the support member by axially translating the slide release toward the latch to urge upon and retract the mounting pin from the slot.

  • Patent number: 5393161
    Abstract: By virtue of its modular construction, this external fixator makes it possible to position the pins (21 to 25) in the bone fragments (11 to 13) taking account of anatomical criteria. The pins are at least indirectly integral with universal joints (36 to 38) with balls (46 to 48) permitting the orientation of the pins relative to connecting bars 503 and 504. The external fixator additionally comprises connecting pieces for articulation between the connecting bars (501 to 507), such as the articulation (7), the telescopic connecting piece (8) and orientable connecting pieces (97 to 99). After the onset of osseous consolidation, some of the connecting bars and their connecting pieces can be removed, it being possible for the bars (501,502) to be withdrawn from the vices (65, 66).

  • Patent number: 5267818
    Abstract: An arrangement for providing universal movement of a machine tool is provided in which there are parallelogram linkages, one of which has a link which maintains parallelism with a worktable and is movable in any direction in a plane. A machine tool is carried by this link to perform an operation on a workpiece on the worktable. Two linear actuators converge from pivotal mountings on the worktable to the link. Selective extension and retraction of the actuators causes appropriate planar movement of the machine tool. A limit switch arrangement is provided by marking the movement of a portion of the mechanism on a plate as the mechanism is extended to its limits, cutting out the plate along the line marked, and positioning the actuating arm of a limit switch in the opening. Movement to the limits of the mechanism's travel will trip the switch and interrupt power to the actuators.

  • Patent number: 4377359
    Abstract: A nut device permitting securement of and to thin panel members. An axially extending, internally threaded shank has two laterally extending flanges interconnected to one end, the flanges being bent downward. Two beam members extend laterally from the shank in a direction which is generally perpendicular to the flanges, the ends of the beam members being bent upwardly toward the flanges. The nut is inserted in a slot in the panel by positioning the beam members parallel to the slot, pushing downwardly on the beam members to flex the flanges so that the beam members may be rotated clockwise beneath the panel. The flanges and beam members cooperate to frictionally clamp the panel and resist lateral and rotational displacement relative to the panel. A specially configured tool is also disclosed.

  • Patent number: 4076437
    Abstract: A positive cam lock for a pair of telescoping extension poles. The cam support is mounted to the inner pole and carries a coaxially rotatably mounted idler cam and an eccentrically rotatably mounted locking cam. The outer pole has a number of inwardly extending splines which engage corresponding grooves on the locking and idler cams. When the outer pole is rotated, the eccentric cam will rotate and lock the outer pole at a desired axial position with respect to the inner pole while the idler cam prevents misalignment. A key mounted to the locking cam rides in a keyway on the cam support for preventing over-rotation of the locking cam.
