  • Patent number: 5316323
    Abstract: The tool holding cartridge is male and the second cartridge holding part is female and defines a cylindrical bore with diametrically opposed apertures near the forward face of the bore, the apertures carrying ball bearings, biased, so that a substantial portion of the ball bearing intersects and projects into the cylindrical bore. Those portions of the ball bearings that do so, act as a guide and locking means for the tool holding cartridge which has a cylindrical shaft which extends into a tool holding portion into which a tool may be anchored or secured, as may be required. The tool holding cartridge has, along the outer walls of the cylindrical portion thereof, near the proximate end of the cylindrical portion, a circumferential race that intersects with the proximate ends of two diametrically opposed axially oriented lead raceways defined in the outer perimeter of the cylindrical portion and that terminate at the outer shoulder and peripheral wall at distal end of the cylindrical portion.

  • Patent number: 5092499
    Abstract: This invention relates to a delivery assembly for delivering molten metal, to a die-casting machine. The system includes a die-casting liquid metal injector with an operative piston having a cylindrical shuttle valve within the assembly and providing for a lower end portion of the assembly to communicate directly to a reservoir of molten metal, particularly corrosive molten metal such as liquid aluminum or the like. In that respect, the injector surface having contact with the corrosive liquid metal are preferably made of a fine ceramic or composite thereof and in the preferred embodiment by partially stabilized Zirconia. The piston, during its molten metal charging stroke, moves the shuttle away from closing off the inflow conduit which communicates to the liquid metal reservoir supply and the internal cavity defined by the assembly is charged with liquid metal.

  • Patent number: 5085203
    Abstract: In barbecuing, food generally sticks to a fixed grill rack. This invention provides means for keeping the food "unstuck" while cooling and this is achieved by moving two adjacently disposed grilling racks, one having a fixed elevation relative to the underlying coals, the other relatively movable from a plane beneath that of the fixed rack to a plane above the fixed rack, thereby causing the food to move between movable rack and fixed rack, keeping the food "unstuck".

  • Patent number: 5044778
    Abstract: Concrete septic tanks have inflow and outflow orifices and near the outflow orifice have screening or baffles which are stapled or bolted to the concrete inner wall so as to force the outflowing liquids to pass a predetermined flow path with the hope to avoid solids passing out of the tank and into a draining tile bed. A novel baffle structure and device for attaching the baffles is disclosed using a linear race with forward and rearward recesses and flexible marginal flap that seals the race onto a core surface of a mold use to fabricate the tank. After the concrete is poured into the mold and partially cured the core is then removed, and the track remains embedded in the concrete and acts as a holding, sealing and anchoring for a baffle, preferably made of a non-corrosive material such as a plastic. The baffle is slipped into the race of the track and seepage across the baffle interface with the tank walls is avoided and the predetermined flow path for the outflowing fluids is ensured.

  • Patent number: 5024079
    Abstract: Significant time is wasted in proving the integrity of a weld associated with the welding of a flange onto a pipe. Generally this takes place by bolting the pipe into the circuit and testing the completed circuit. The test plug according to the invention discloses means for placing a seal internal of the pipe and connecting to a flange which has been welded to end of a pipe a flange plate and bolting the flange plate to the flange in the conventional manner. The test plug defines therethrough at least two channels one for conveying into the pipe bounded by the flange plate and the seal a testing media such a fluid or liquid and the other channel for purging the same. The immediate area around the weld can thus be tested for improper welding rather than requiring the total pipe link to be tested in situ.
