  • Patent number: 10538455
    Abstract: A lathe-based system may include chucks to retain a glass core rod, an arm, a slip joint, an actuator system, and a control system. The slip joint may couple the arm and a first chuck in fixed relation against relative axial motion with respect to an axis of rotation. The slip joint may also couple the arm and the first chuck in two-dimensionally movable relation with respect to a plane normal to the axis of rotation. The actuator system may be configured to two-dimensionally adjust a position of the first chuck in the plane. The control system may measure straightness of the glass core rod and control the actuator system in response to optical measurements of the straightness. In this manner, the system may straighten the glass core rod. The system may simultaneously elongate the glass core rod as it straightens the glass core rod.

  • Patent number: 9951900
    Abstract: An external seal for sealing against an elbow fitting of a fluid line has an elbow clamp and a seal. The elbow clamp has a first part that is sized and shaped to engage the outer radiused curve of the elbow fitting, and a second part that engages the inner radiused curve of the elbow fitting. The first part defines a tool opening and a tool engagement profile sealingly engages a valve in axial alignment with the tool opening. A clamping member brings the first part into engagement with the outer radiused curve of the elbow fitting. The seal is adjacent to the first part of the elbow clamp in line with the tool opening and seals around the tool opening between the elbow clamp and the elbow fitting when the clamping force is applied.

    Abstract: An apparatus to aid in the making of a light filtering window shade from shade fabric comprised of a series of longitudinal vane members having their longitudinal edges respectively secured to front and rear fabric panels. The apparatus comprises an assembly table and a roller tube positioning rail. The table has first and second ends with the first end adapted to facilitate the cutting of the shade fabric to a desired length. The roller tube positioning rail is releasably securable to the assembly table and releasably receives a roller tube having one end of the shade fabric secured thereto. The positioning rail permits the roller tube, and the shade fabric secured thereto, to be set-off a predetermined distance from the first end of the assembly table. The positioning rail maintains the roller tube generally parallel to the first end of the assembly table.

  • Patent number: 9393739
    Abstract: For use in loading heavy sticks of plastic pipe into a pipe fusion machine, a pipe storage rack with hydraulically powered pipe stick dispensers and stands allows sticks of pipe stored on the rack to roll gravitationally onto a rocking V-shaped dispenser cam disposed between the rack and the fusion machine loading path for one-stick-at-a-time loading onto powered track and roller stands which enable Cartesian manipulation of the stick into the fusion machine. The cam is adjustable to suit pipe stick diameters ranging from 20? to 48?. Many sticks can be stored at one time, releasing heavy lifting equipment and operators to work elsewhere. The process requires only one operator using a pendant controller and the pipe sticks are handled by heavy equipment only when being loaded onto the racks.

    Abstract: There are disclosed methods of and apparatus for interconnecting lined metal pipes (110, 120), applying in particular to the offshore oil and gas industry. Corrosion is a common problem in the industry. Lining pipes overcomes the problem, but welding sections of pipe together can be a complicated and time-consuming task, requiring dedicated and sophisticated tooling. More desirable is the ability to use conventional pipe-laying equipment (20, 40, 50, 60, 70, 80, 90) with little additional tooling. As such, there are disclosed methods and apparatus compatible with known offshore connection methods, particularly where the spacing of joints on the pipe is less than 100 m. The chosen technique will not significantly impact the laying rate of the lined pipe, compared with unlined pipe.

  • Patent number: 7866532
    Abstract: A method of performing friction stir welding is provided herein. More specifically, traditional friction stir welding requires a rotatable head that is forced against a plurality of work pieces to bond the same. The rotational and normal forces generated by the friction stir welding tool are generally reacted by a backing plate, anvil, mandrel or other mechanisms, such hardware are subject to the applied forces and are often supported with additional internal supports. Conversely, a method of performing a friction stir weld is described that omits the need for such a backing member and internal supports as it is performed using a self reacting pin tool.

  • Patent number: 7699207
    Abstract: An internal ring assembly for welding backup against internal hoops of pipes or tanks has a chain assembly of diverse cells. A majority of the cells include a tile of conductive metal for abutting inside walls across a seam of two sections of pipe or tank to be welded, as well as a cell of a roller chain assembly comprising either both a pin-link and roller-link construction or alternatively a pair of mosaic-link constructions. In either case, one of such link constructions is anchored to the tile and the other extends free of the tile for linking with another cell of the chain assembly. In contrast, a minority of the cells are arranged to produce an expansion force on the chain assembly as a whole in order that the chain assembly expansively forces itself tightly against the inside seam of the pipe or tank sections.

  • Patent number: 7661345
    Abstract: A device (10) for clamping and separating a length of tubing. The device (10) comprises first and second subassemblies (12,14) for, in their closed positions, clamping the tubing at first and second locations, respectively, and at least weakening the tubing for subsequent separation. The subassemblies (12,14) face each other and are connected by a breakable connection. Each subassembly (12,14) includes clamping elements (26,34) for clamping the tubing, a perforating or cutting element (28) for perforating or otherwise weakening or cutting the tubing, and locking elements (24,32) for locking the subassembly (12,14) in the closed position. The perforating element (28) may be at least one hard plastic or metal spike. Once each subassembly (12,14) is locked in the closed position, the breakable connection is broken to result in respective lengths of clamped tubing.
