Patent number: 6427555Abstract: A drill-chuck jaw is made by first forming an elongated metal body with a toothed back face and a front face, then machining a longitudinally extending groove having sides and a floor in the front face, and forming inwardly projecting and longitudinally spaced retaining bumps on the groove sides. A hard-metal insert is fitted into the groove between the retaining bumps and then bonded to the body in the groove. the body is heat-treated, that is annealed, before machining the groove in it to reduce internal stresses.

Patent number: 6249952Abstract: A method of making a balloon expandable braided stent with a restraint to initially prevent self-expansion and the resulting product. Multiple strands of a resilient metal or plastic are braided to form a tubular configuration of a predetermined outside diameter which assumes a lesser diameter when the tubular stent is longitudinally stretched. When in its stretched condition, it is coated with a polymeric material which is then cross-linked to effectively “freeze” the intersections of the braided structure holding it in its reduced diameter configuration. The tubular stent is designed to be placed within a body vessel using a balloon stent delivery catheter. When the balloon surrounded by the braided wire stent is inflated, the stent expands initially to an extent to break the bonds of plastic material between the intersections of the strands, thereby permitting self-expansion to take place.Type: GrantFiled: March 8, 1999Date of Patent: June 26, 2001Assignee: SCIMED Life Systems, Inc.Inventor: Ni Ding

Patent number: 5884383Abstract: A connector for a composite pipe includes a male conical member to be inserted between inner and outer layers of the pipe. The outer layers have oppositely wound composite strips which are overlapped along the conical surface. The ends of the strips are braided and a cup located over the conical surface. A filler is injected between the cup and conical member to fill the voids formed between the overlapping strips.Type: GrantFiled: November 11, 1997Date of Patent: March 23, 1999Assignees: Donald H. Wolfe, David R. BudneyInventors: Donald H. Wolfe, David R. Budney

Patent number: 5881460Abstract: An apparatus and method for fastening concrete reinforcement steel members together using deformable metal fastener clips. The concrete reinforcement steel members are used to strengthen concrete structures in a known manner and can be in the form of wire mesh sheets or rebar positioned in a grid pattern. The deformable metal fastener clips are generally U-shaped members that are open on one side before being deformed so that the fastening clips can be easily placed over two or more adjacent reinforcement steel members. The metal fastener clips are deformed around the reinforcement steel members to close the open side of the metal fastener clips, thereby securing the reinforcement steel members together in a desired formation. The free ends of each fastener clip preferably overlap each other after the fastener clips are closed around the reinforcement steel members.Type: GrantFiled: September 10, 1997Date of Patent: March 16, 1999Inventors: Stephen C. Nowell, III, A. Carter Nowell
