  • Patent number: 7268317
    Abstract: The invention relates to a method and apparatus for improving properties of a solid material by providing shockwaves there through. Laser shock processing is used to provide the shockwaves. The method includes applying a liquid energy-absorbing overlay, which is resistant to erosion and dissolution by the transparent water overlay and which is resistant to drying to a portion of the surface of the solid material and then applying a transparent overlay to the coated portion of the solid material. A pulse of coherent laser energy is directed to the coated portion of the solid material to create a shockwave. Advantageously, at least a portion of the unspent energy-absorbing overlay can be reused in situ at a further laser treatment location and/or recovered for later use.

  • Patent number: 7111549
    Abstract: A guide system is provided to slidingly guide a reciprocating dynamic balancer weight within a press machine. An elongate stationary guide rail is disposed within a vertical channel formed at one side of the balancer mass. In this configuration, the guide rail is arranged in guide support relationship to the balancer mass. An arrangement of wear plates is mounted to the guide rail to provide additional bearing support to the reciprocating balancer mass. An arrangement of hydrostatic pads is mounted to the guide rail in facing opposition to the balancer mass to enable the formation of a hydrodynamic/hydrostatic lubricating action therebetween during reciprocation of the balancer mass. A machined steel plate is secured to the balancer mass at the same side where the guide rail is located and includes a set of lateral apertures formed therethrough that receive guide support members extending therethrough. The guide support members anchor the guide rail to the press crown.

  • Patent number: 7105001
    Abstract: A small intestine submucosa mesh is adapted for use in surgical abdominal closure routines. The submucosa mesh is incorporated into the normal surgical protocol for abdominal closure procedures. The submucosa mesh is applied to the abdominal incision area and maintains and enhances the stability and integrity of the abdominal wall closure, thereby preventing the onset or occurrence of incisional hernias. The submucosa mesh can also be applied to surgical closure procedures involving treatment of a hernia defect, such as an incisional hernia or other non-incisional hernia. The submucosa construct can also be adapted for use as a suturing component or bioretention suture. The submucosa construct can be adapted for use as part of a surgical strategy to facilitate wound healing, regeneration, reconstruction, and replacement of anatomical structures, such as tissues and organs.

  • Patent number: 7051756
    Abstract: A pressure relief valve includes a cylindrical poppet having a fluid metering stem. The valve is configured such that the effective surface area of the transverse aspect of the poppet exposed to fluid pressure during a closed valve condition is greater than the effective surface area of the transverse aspect of the poppet exposed to fluid pressure during an open valve condition. This feature creates a narrow spread for cracking to reseat pressure points since the surface area of the poppet available to experience fluid-related pressure is reduced as the valve moves from its closed to open position. While closed, the poppet is exposed to fluid pressure at the axial end face of the stem and at an annular end face portion of the poppet defined by the clearance between the stem and fluid channel. While open, the poppet experiences fluid pressure at the end face of the stem.

  • Patent number: 7024913
    Abstract: An adjustment stroke connection for a mechanical press includes an eccentric bushing disposed within a press connection member and an eccentric crankshaft member disposed within the eccentric bushing. A rotatable crankshaft is connected to the eccentric member. A mechanism is provided for connecting the eccentric bushing with the press connection member in a manner that prevents rotation therebetween and concurrently permits rotation of the eccentric member relative to the eccentric bushing. When the mechanism is activated, driving rotation of the crankshaft produces a press stroke adjustment. A torque actuator delivers equal driving torque to plural eccentric crankshaft members to enable minimization of relative bushing angle slip. Suitable control of the bushing angle and slide position crank angle during bushing expansion and contraction also minimizes relative bushing angle slip.

  • Patent number: 6925396
    Abstract: An instrument system for a press machine environment includes a monitoring apparatus to determine the flywheel speed, slide speed, and slide displacement relative to, for example, Top Dead Center. These measurements are used to determine the energy consumed by the slide as a function of slide displacement as its travels during its work stroke. A piston-cylinder combination is disposed at a die location to emulate a die set and to facilitate a determination of the load developed by the slide as it actuates movement of the piston. A computation of the work produced by the slide during piston movement can be determined on the basis of measurements of piston displacement and slide-induced pressure applied to the piston. A display plots various graphs to depict slide energy, slide work, and flywheel speed as a function of slide displacement.

  • Patent number: 6880412
    Abstract: A device and method for testing the tension in a stressed cable of a concrete structure. The device includes a frame and a hydraulic jack mounted onto the frame. The hydraulic jack applies a force to the stressed cable and displaces the stressed cable laterally. A hook or clamp is connected to the hydraulic jack for grasping the stressed cable in order to apply the force thereto, and a dial gauge is mounted onto the frame for measuring the deflection of the stressed cable once the force has been applied. The amount of pre-stress within the stressed cable can be calculated by measuring the amount of deflection caused to the stressed cable by the force of the jack.
