  • Patent number: 7429065
    Abstract: An assembly includes a first member having an inner surface and a second member having an outer surface. One of the two members has greater rigidity than the other member and at least one groove. The rigid member is partially received within the less rigid member and a coupling mechanism provides radially inward pressure to generate a seal between the inner surface of the first member and the outer surface of the second member. The groove includes an opening and a base each having a predetermined width. The predetermined width of the opening is generally less than the predetermined width of the base. The more rigid member may comprise an insert with a surrounding sleeve wherein the sleeve includes the grooves.

  • Patent number: 6981512
    Abstract: An integrated in-line tube and check valve assembly fabricated by end-form mandrel expanding an outlet end portion of deformable tube stock, such as metal, of nominal starting diameter, and concurrently end-forming a valve seat on the inside of the expanded tube section where it necks down and integrally joins the upstream nominal diameter portion of the tube. A valve ball and a valve spring are then fitted into the expanded tube section, together with a spring holder if needed. The expanded end portion of the tube is then again deformed by an end-form swaging operation that reduces the diameter of the expanded tube outlet end so as to form a cavity within the tube in which the spring is captured in compression for resiliently biasing the valve ball against the valve seat.

  • Publication number: 20030199092
    Abstract: A method is provided whereby altered cells exhibit increased intracellular half-life of transcribed mRNAs resulting in increased levels of expressed and/or secreted proteins. The cells are genetically altered to increase the level of intracellular ribosome receptor, which induces mRNA half-life.

  • Patent number: 6127566
    Abstract: The present invention provides a continuous process for making O,O-dimethyl phosphoroamidothioate. In accordance with this process, O,O-dimethyl phosphorochloridothioate is reacted with ammonia and sodium hydroxide; addition of the sodium hydroxide controls the pH of the reaction mixture. The formed reaction mixture contains an aqueous phase and an organic phase. The organic phase of the reaction mixture is separated from the aqueous phase; a second organic phase is solvent extracted from the aqueous phase; and the resultant O,O-dimethyl phosphoroamidothioate is isolated from the combined organic phases via vacuum solvent stripping. In an embodiment of the present invention, the reaction of O,O-dimethyl phosphorochloridothioate with ammonia and sodium hydroxide is carried out in the presence of a solvent.

  • Patent number: 5266048
    Abstract: A gull-wing strain relief (10) for a flat multi-conductor ribbon cable (30) exiting a connector assembly (20). The gull-wing strain relief (10) is mounted directly on the connector assembly (20) and includes lateral flaps (14) which close around the connector assembly (20).

  • Patent number: 5127152
    Abstract: An assembly for wiring a terminating tool (6) having wire combs (34,36) comprises a tool mount (164), a bench stand (166) and a clamp (168). The tool mount (164) has a clevis (178) for receiving one end of the tool (6) and a screw (187) for securing the tool (6) to the clevis (178). There depends from the clevis (178) a support leg (170) which is received between side walls (190) of the bench mount (166) which is mounted on the top surface of a work table (210). The clamp (168) has a clamp post (204) which is passed through notches (194) in the walls (190) of the bench mount (166) and through a hole (172) in the support leg (170), so that the tool mount and thus the tool (6) can be rocked about the axis of the clamp post (204). The clamp (168) has a clamp screw (200) which can be tightened against the underside of the work table (210) so that the clamp post (204) urges the bench mount (166) against the top side of the work table (210).

  • Patent number: 4696472
    Abstract: A throwing toy is comprised of a spherical ball filled with foam rubber, and a long tether tail, one end of which is anchored within the center of the ball. The tail is preferably a light weight strong ribbon having visibly distinctive indicia. The tether is used to swing the toy prior to its release for airborne travel, and to catch the toy upon its descent. The ball includes a diametrically aligned slot and cylindrical channel. One end of the ribbon is anchored at the center of the ball, where the slot meets the channel. The ribbon is assembled to the ball by inserting a tool including a hook into the slot, then through the cylindrical channel, and then hooking a loop at the end of the ribbon, and then pulling the loop to the center of the ball. The loop containing end of the ribbon may be withdrawn from the ball through the slot, and a metal rod may be placed in the loop, which is then pulled into its anchoring position at the center of the ball.

  • Patent number: 4682391
    Abstract: Cable harness manufacturing apparatus comprises a pair of rails defining a linear path through a workstation where a press terminates ribbon cable to connectors in connector receiving fixtures independently journaled to the rails. A first stop on the path positions connectors sequentially at the workstation while a series of second stops along the path downstream of the workstation act on the lead fixture to define the length of cable between pairs of connectors as well as triggering the press for sequential terminations of connectors in remaining fixtures. A cutter carriage journaled to the rails upstream of the workstation is spring loaded to urge remaining fixtures to the workstation. A third stop along the path downstream stops the lead fixture when it is desired to cut the cable, the cut end subsequently being drawn flushly into the last connector terminated.
