  • Patent number: 8782898
    Abstract: A method for fabricating a hollow bar that forms elements of a grille or railing of a metalwork piece where the bar is twisted manually, machine-assisted or automated machinery, into a spiral form for decorative or ornamental purposes. By providing the hollow bar to be comprised of separate longitudinal parts which may be hinged-joined to complementarily fastened to each other to form the hollow bar, the longitudinal joints are thus amenable to increased torsional stress, such that each of the parts may be twisted without breaching the material's fatigue limit and the bar as a whole capable of being twisted with more spiral turns within its elasticity limits. The twisted bar may thus be released for re-working for adjustments or re-installation. A number of exemplary joint embodiments, internal and external bracing accessories are also disclosed to cater for the different longitudinal part fabrication, e.g. by extrusion or roll-milling.

    Abstract: An apparatus and method for applying tension to flexible items, including wire, barbed wire, cable, or rope, are described herein. A stationary clamping member is fixedly attached to a first end of a guide bar, extending outwardly therefrom, while a non-stationary clamping member is movably mounted to and extending outward from the guide bar substantially parallel to the stationary clamping member. The free end of a first flexible item is secured in the stationary clamping member, while the free end of a second flexible item is secured in the non-stationary clamping member. A tensioning assembly, such as a ratchet-like assembly engaging notches in the guide bar, is used to move the non-stationary clamping member away from the stationary clamping member, thereby tensioning one or both flexible items. Once the flexible items have been tensioned, they can be twisted together to form a connection without losing tension.

    Abstract: A preload locking wire insert comprised of a unitary, coiled wire having a particular polygonal cross-section for use in combination with a threaded fastener and a complementary threaded bore in a work piece, wherein the wire insert provides a ramping surface which locks the threads of the fastener into place against the inner threaded wall of the bore in the work piece. A further embodiment provides for the wire insert to be threaded into the bore in either direction, with no regard to orientation, while still retaining the definitive locking aspect.

  • Patent number: 7637136
    Abstract: A method of working metal in which the microstructure of metal body is rendered fine to thereby enhance the strength, ductility or homogeneity thereof; a metal body obtained by the metal working method; and a metal-containing ceramic body obtained by the metal working method. In this metal working method, the deformation resistance of metal body or metal-containing ceramic body (hereinafter referred to simply as “metal body”) is lowered locally to thereby form low deformation resistance regions in the metal body, and shear deformation of the low deformation resistance regions is effected so as to fine the microstructure of metal body. In particular, the metal body is formed in unidirectionally drawn configuration so as to produce low deformation resistance regions crossing the metal body.

  • Publication number: 20090249852
    Abstract: A pouring reel for forming a long product moving at an incoming velocity into an annular coil comprises a central mast lying on a vertical axis. A cylindrical tub surrounds and cooperates with the mast to form an annular chamber, the bottom of which is closed by a coil plate. An entry pipe is arranged to deliver the product downwardly for accumulation in the chamber as a series of superimposed rings forming the annular coil. A first drive mechanism rotates the tub about the vertical axis, and a second drive mechanism rotates the mast about the same axis. The first and second drive mechanisms are operable independently of each other to thereby permit the tub and the mast to be rotated at surface velocities substantially matching the incoming velocity of the product.

  • Patent number: 7477965
    Abstract: A twisted wire actuator, whereby the shortening of the length of a wire or a bundle of wires, as it is twisted, is used to control the motion of an actuated element, achieving sub-micron motion resolution. The control can be performed robotically. The high resolution can be achieved without the use of gears, sliders, or high precision lead screws, thus enabling a simplified actuation system and eliminating sources of friction. The use of wires operating in opposing directions and having oppositely directed rotations significantly reduces the non-linearity effect inherent in twisted wire actuation, resulting in a system having a good level of motion linearity as a function of control input impulse. The use of multiple twisted wires attached to the actuated element at different angles, enables the implementation of robotic systems with multiple degrees of freedom. Several experimental actuators verify these results.

A first cable displacement device (12) longitudinally displaces the first clamp (2) relative to the second clamp (3) along the longitudinal axis (4). A first clamp rotation device (14) rotates the first clamp (2) relative to the second clamp (3) about the longitudinal axis (4). The apparatus also has a second clamp displacement device (19) for simultaneously longitudinally displacing the first and second clamps (2, 3) along the longitudinal axis (4).

  • Patent number: 7434437
    Abstract: In a method of making a metallic thin wire 1, one single metallic thin wire 2 is prepared to have a predetermined length with a middle portion of the one single metallic thin wire 2 as a fixed portion. Front and rear half portions of the one single metallic thin wire 2 are twisted with a tensile weight W applied to the front and rear half portions in the lengthwise direction. The one single metallic thin wire 2 is processed with a heat treatment to remove a residual stress. This provides the metallic thin wire 1 with a high rotation-following capability and high torque transmissibility, thus enabling artisans to usefully apply the metallic thin wire 1 to a main wire component 25 of a medical tool and equipment.
