  • Patent number: 5530984
    Abstract: An eraser is disclosed. The eraser includes a frame formed of tubular components coupled together. The frame includes a first peripheral member having long parallel side edges, a short rear edge and a triangular shaped front edge. The side edges are about twice the length of the rear edge. Three cross-brace members including a front cross-brace member constitute the base of the triangle. Additional cross-brace members are at equally spaced locations on the interior faces of the side edges. A handle is formed of a rod extending upwardly from the central extent of the forward cross brace. The handle extends rearwardly at a right angle to and over the central cross brace member with a plastic grip member of an enlarged diameter with finger receiving recesses on its lower extent secured to the end of the handle remote from the frame. A flexible cover is secured over the lower surface of the frame and is essentially co-extensive therewith.

  • Patent number: 4226240
    Abstract: Surgical forceps comprising cross members having a pair of gripping arms pivotally connected to a pair of clamping arms comprising a pair of end members directed away from the axis of the gripping arms and terminating with a pair of slightly curved mating jaws having aligned notches disposed on their outer surfaces to accommodate a needle for sutures. The pair of mated jaws are disposed in a plane substantially perpendicular to the plane containing the pair of end members.

  • Patent number: 3998047
    Abstract: A method and apparatus for preventing overspeed in a gas turbine in response to the rapid loss of applied load is disclosed. The method involves diverting gas from the inlet of the turbine, bypassing the same around the turbine and thereafter injecting the diverted gas at the turbine exit in a direction toward or opposing the flow of gas through the turbine. The injected gas is mixed with the gas exiting the turbine to thereby minimize the thermal shock upon equipment downstream of the turbine exit.
