  • Patent number: 5562809
    Abstract: A method for making metastable compounds of Me metal, argon and hydrogen, comprising the steps of generating a high frequency plasma discharge in a flow of hydrogen-argon gas mixture, the plasma discharge having a higher temperature plasma generating active region and producing a flow of plasma downstream of the plasma discharge; establishing a zone of substantially zero axial flow of the mixture within the active region of the plasma discharge relative to the flow of plasma immediately downstream of the generating means; introducing finely powdered Me metal into or near the zone and within the active region at a rate conducive to evaporation of the metal in the plasma discharge; rapidly cooling the reaction products resulting from interaction of the Me metal with the plasma to precipitate a solid component; and passivating the surface of the solid component.

  • Patent number: 5555778
    Abstract: An opener tool having a working end, a convexly curved underside portion and a handle. The working end is dimensioned for insertion under the ring portion of a pull tab without lifting the pull tab ring sufficiently to bread the seal of the can top. The tool further has a stop element for limiting insertion of the working end through the finger opening.

  • Patent number: 5534208
    Abstract: A continuous rotary method for surface shaping of resilient material such as synthetic foam. Three dimensional surface geometries of well defined and arbitrary shapes are obtained by pressing foam against a die roller to compress some foam portions to a reduced thickness against raised portions of the die and extrude other foam portions into depressions of the die, and cutting away the extruded portions. The compressed portions return to an uncompressed state after passage against the die roller and form raised areas on the foam surface around depressions corresponding to the cut away portions of foam.

  • Patent number: 5531696
    Abstract: A syringe, particularly for epidural anesthesia, has an elastomeric driver in the form of a single elastic band perforated for mounting onto the tip of the syringe between the barrel and the needle hub. The elastic band is stretched into engagement with the thumbrest of the plunger to drive the plunger to full depression into the syringe barrel. The elastic band extends symmetrically on either side of the barrel to apply balanced force. Various configurations for the elastic band are disclosed.

  • Patent number: 5449976
    Abstract: A control unit for controlling a strobe light or the like, in particular for use in an alarm system or an emergency locator, is characterized in that a direct current power supply unit is provided which is activated to drive the strobe light when an external power supply unit which is adapted to drive the strobe light is deactivated.

  • Patent number: 5435246
    Abstract: A kit for applying stamping identification onto compact discs includes a base for supporting a compact disc, and a hand stamp with a spring loaded spindle sized to fit into a hole in the base for centering the stamp relative to the disc. The spring force on the spindle must be manually overcome to apply the stamp to the disc and helps maintain uniformity of stamping force. The stamp assembles with an inkwell unit for clean and convenient storage of both stamp and inkwell.

  • Patent number: 5431938
    Abstract: A composite seafood product is made by assembling smaller butterflied shrimp into composites of two to four shrimp, all but/one of which are tailless, resembling in appearance a single large butterflied shrimp. The shrimp composites are dusted and frozen apart from each other to retain individuality. The individual composites can then be coated with batter and deep fried to yield a food product seemingly consisting of large individual shrimp.

  • Patent number: 5429546
    Abstract: Whole crayfish is processed to derive a food serving resembling in appearance a small lobster by deheading the crayfish, making a U-shaped incision around the belly shell encompassing the anal opening of the crayfish, and peeling away the belly shell including the anal opening and the digestive tract still attached to the anal opening, thereby to devein the crayfish and expose the edible flesh contained in the hard shell in a single operation. When subsequently heated during cooking, the flesh tends to curl slightly away from the hard shell for easier extraction.

  • Patent number: 5429170
    Abstract: An apparatus is provided for operating a segmented sliding overhead door. The door is of the type for sliding in a pair of side tracks mounted at either side of the door between a dosed vertical position and an open horizontal position. A driver is mounted at the side-to-side center of the door and extends away from an interior side of the door. The driver includes a screw drive shaft adapted to be mounted horizontally above the door. A motor is engaged with the drive shaft and provides reversible rotational drive force to the drive shaft. A drive shaft coupling unit engages the drive shaft for moving along the drive shaft in response to rotation of the drive shaft. A track assembly engages and supports the rotating drive shaft and guides the coupling unit in linear travel along the drive shaft. A door connecting rod assembly serves to rigidly jam the door against the floor when the door is in the fully closed position, and connects the carrier unit to the door for moving the door along the side tracks.

  • Patent number: 5416530
    Abstract: Video noise reduction is achieved by limiting the loop response bandwidth in a phase locked loop demodulator with a high-pass RC network connected between two oppositely phased video signals in the phase detector for out-phasing a high frequency component of the loop response bandwidth. Easy user adjustment allows viewable video images to be obtained from very noisy signals in deep fringe reception areas.
