  • Patent number: 8596514
    Abstract: The invention pertains to a method and apparatus for delivering an article formed of a shape memory alloy to a surgical implantation site. The apparatus may include a body having a passage for receiving the proximal portion of the shape memory article, the passage being shaped to substantially prevent the shape memory article from deforming in accordance with its shape memory properties when the proximal portion of the shape memory article is positioned in the passage. An exemplary involves placing the distal portions of legs of a staple in at least one passage in a constraining device that substantially constrains the legs from deforming; and placing the proximal portions of the legs of the staple in at least one passage in an apparatus that, independently of the constraining device, substantially prevents the legs from deforming.

  • Patent number: 8109706
    Abstract: A composite fastener, a belly nut, a tie system and/or a method reduce heat transfer through a building envelope. The composite fastener, the belly nut, the tie system and/or the method secure a wall to a backup structure. The composite fastener is constructed from a fiber reinforced polymer that has fibers embedded in a polymeric matrix. The composite fastener has a low thermal conductive value (k-value) and has non-corrosive properties. The belly nut has a fastening hole on a first side of the belly nut to attach the composite fastener to the belly nut. Further, the belly nut has a pathway to receive a leg of a pintle from a top surface of the belly nut to a bottom surface of the belly nut. The pathway is sized to allow for greater vertical adjustment eccentricity between the belly nut and the pintle without creating large horizontal deflections of the tie system.

  • Patent number: 8083452
    Abstract: A hybrid clinch-type standoff consists of two component parts, a metal core base and a overmolded plastic barrel. The base has a through-bore and a displacer flange at the bottom. A first undercut is located immediately above the flange and extends upwardly along an outside surface of the base for providing clinch attachment of the base to a substrate. A frustoconical ramp convergent in the upward direction lies along the outer surface of the base is and is located directly above the first undercut. An axially extending segmented ring with circumferential teeth is located at the top of the base. The overmolded plastic tubular barrel composed of plastic fills the second undercut and surrounds the segmented ring. The barrel has an inner portion including a threaded inner wall which extends downardly inside the through-bore to a point flush with the bottom of the flange.

  • Patent number: 7988395
    Abstract: A relatively low cost, lightweight and thermal stress-free mechanical fastener system having particular application for reliably joining together high temperature structural members (e.g., a pair of flat fiber-reinforced ceramic composite plates). The mechanical fastener system includes a ceramic composite fastener having a semi-circular head at one end to be countersunk in the structural members to be joined together and a dove tail retention feature formed in the shank or root at the opposite end. The composite fastener has a 2-dimensional (i.e., flat) profile that facilitates an economic manufacture thereof from densified ceramic composite material. A matched pair of thread forms having external threads and an internal dove tail relief to match the dove tail retention feature at the root of the composite fastener is held in face-to-face mating engagement with one another so as to establish a mechanical interlock around the root of the composite fastener.

  • Patent number: 7967562
    Abstract: A fastener for a turbine engine includes a bolt and a ceramic matrix composite (CMC) cap mechanically secured to the bolt. CMC components are attached to an exhaust nozzle case with the fasteners. The fastener includes a bolt made of metal and having a head. A CMC cap is located on the head of the bolt and secured to the bolt by a mechanical device. The mechanical device allows the CMC cap to have a different thermal expansion than the bolt. The CMC cap also acts as a thermal shield for the bolt, aiding in the reduction of a heat signature of the turbine engine.

  • Patent number: 6676785
    Abstract: A method and apparatus for forming an improved pultruded and clinched Z-axis fiber reinforced composite laminate structure. The upper and lower skins and the core are pulled automatically through tooling where the skin material is wetted-out with resin and the entire composite laminate is preformed in nearly its final thickness. The preformed composite laminate continues to be pulled into an automatic 3-dimensional Z-axis fiber deposition machine that deposits “groupings of fiber filaments” at multiple locations normal to the plane of the composite laminate structure and cuts each individual grouping such that an extension of each “grouping of fiber filaments” remains above the upper skin and below the lower skin. The preformed composite laminate then continues to be pulled into a secondary wet-out station.

  • Patent number: 5258009
    Abstract: A malleable, bioabsorbable polymeric staple includes a back span with two legs depending perpendicularly therefrom that are deformed along an arcuate path toward each other initially and then upwardly toward the back span such that end points on each leg extend through a gap formed between an underside of the back span and a bend in an opposite leg. A surgical staple-deforming anvil for deforming the staples has a staple-receiving face formed with a pair of guiding path depressions each having an entry end lying on a longitudinal axis parallel to the back span of the staple, and an exit end. The guiding paths are arcuately shaped and form a groove curving and crossing each other approximately at the longitudinal axis. Accordingly, the legs of a staple driven toward the anvil and received in the guiding paths are initially bent toward each other and then steered upwardly and along the horizontally curved path toward the gap formed between the back span and the bend in the opposite leg.

  • Patent number: 5007781
    Abstract: The tapered split-bushing fastener has been designed for high temperature applications. The fastener consists of a pin (with a standard countersunk head at one end and a tapered end at the other end), a split tapered bushing, a washer and a sleeve with an internal taper. Installation is accomplished by inserting the pin in the parts to be fastened, then slipping the washer and the split bushing on the tapered end and finally pushing the sleeve onto the split bushing. Pushing the sleeve causes the split-bushing to react against the washer and generate the fastener axial preload. A high temperature adhesive is then injected to lock the fastener in place.
