  • Patent number: 5037351
    Abstract: A method of weighing poultry includes: conveying a plurality of birds which are closely adjacent to each other toward a weighing station; disentangling the wings of the birds from each other and separating the birds from each other by turning the birds; and then, while the wings of the birds are disentangled and while the birds are separated from each other, weighing the birds at the weighing station. The birds are suspended by their legs from suspension hooks and the suspension hooks are suspended from a conveyor suspension track.

  • Patent number: 4803029
    Abstract: A process for manufacturing an expandable member such as a tissue expander or like product for use in plastic, reconstructive, and other surgery. A compression mold with a desired initial, predetermined geometrical configuration shape is filled partially with a layer of unvulcanized flexible material, such as silicone, a thin layer of Teflon or like non-stick substance, and followed by another layer of unvulcanized material. The Teflon is "sandwiched" between the unvulcanized material and cured in an oven or by other suitable means. The non-stick material provides a separation region for subsequent expansion by injection of suitable material, air, fluid, etc. The non-stick material can be shaped to provide expansion only in the desired regions. Single, multiple, or overlapped layers of non-stick material may be employed to manufacture a variety of expandable products in the fields of medicine, surgery, consumer and industrial applications.

  • Patent number: 4765317
    Abstract: Widely adjustable anterior posterior headblock in a halo vest fixation system of graphite and other material for fixation of a head about an orthopedic jacket with respect to the cervical region, such as for spinal trauma. A slotted adjustment carrier member with ball, sockets and clamping screws at each end of the carrier fits over and between pairs of upright rods. Clamping screws and a slot in the carrier member provide for anterior and posterior movement of a saddle and an attached vertically aligned halo ring traction plate to position an attached halo ring. The halo ring traction plate moves vertically in a slot via an independent-acting, internally-captured adjustment screw to provide for vertical traction or distraction as applied to the halo ring. The halo ring rotates pivotally about a pitch axis to provide for flexion or extension adjustment of the halo ring.

  • Patent number: 4685447
    Abstract: Tissue expander system including a tissue expander, an injection port, and a tube connecting the tissue expander to the injection port. The tissue expander is of a one piece molded body of a pancake to waffle like configuration. Within the one piece molded body is a member of non-stick material of a slightly smaller geometrical shape similar to that of the one piece molded body. A self-sealing valve member closes off the tube in the tissue expander after injection of a solution for expanding the tissue expander. A Dacron mesh can be embedded in members of the one piece body providing for directional expansion of the tissue expander. In an alternative embodiment, Dacron mesh can be provided in both the upper and lower members of the one piece body. An accordion configured perimeter also provides for upward directional expansion. The tissue expanders can assume any geometrical configuration, whether it be square, rectangular, circular, oval, or kidney shaped.
