  • Publication number: 20110248495
    Abstract: A connector (1) for connecting to a tubular member has a body (5, 35, 65) with a bore (7, 37, 67) configured to receive the tubular member, the body having a wedge device (10, 40, 70) within the bore adapted to interact with the body to grip the tubular member (15) when the tubular member is disposed within the bore, wherein the wedge device is at least partially helical, and wherein the connector has an anti-rotation device (23, 53, 83) to restrict relative rotation of the wedge device and the body when the tubular is gripped in the bore.

  • Patent number: 5768156
    Abstract: The present invention is a computer-based method and apparatus for constructing all-hexahedral finite element meshes for finite element analysis. The present invention begins with a three-dimensional geometry and an all-quadrilateral surface mesh, then constructs hexahedral element connectivity from the outer boundary inward, and then resolves invalid connectivity. The result of the present invention is a complete representation of hex mesh connectivity only; actual mesh node locations are determined later. The basic method of the present invention comprises the step of forming hexahedral elements by making crossings of entities referred to as "whisker chords." This step, combined with a seaming operation in space, is shown to be sufficient for meshing simple block problems. Entities that appear when meshing more complex geometries, namely blind chords, merged sheets, and self-intersecting chords, are described.

  • Patent number: 4008886
    Abstract: In a machine tool, particularly a milling machine, the workpiece vice is made up from a vice jaw member having a longitudinal track, and a plurality of insert members having profiled portions complementary to the track, so that a desired workpiece engaging profile may be built up from a plurality of insert members which are engaged with the track and fixed in position by locking means.
