  • Patent number: 6787258
    Abstract: Utility power is wheeled to distributed hydrogen energy storage systems during off peak periods where it is used in an electrolyzer to disassociate water into hydrogen and oxygen. The hydrogen at least is stored for use in a fuel cell or combustion engine driven generator to produce locally generated electricity during peak periods or power interruptions. Efficient electrolysis and gas storage are obtained by operating the electrolyzer at high pressures through two flow loops in which the hydrogen and oxygen produced in the electrolyzer pass to separate gas-water columns and force water into the electrolyzer. When the desired high pressure is reached, the gases are bled off into a series of storage tanks.

  • Patent number: 6519540
    Abstract: A computer controlled signal router has a graphical user interface which pictorially represents the source channels and destination channels as intersecting, perpendicular sets of stripes with the intersections representing the switches of a cross-point switching matrix. Multiple signal channels are arranged in logical planes which may be displayed singly or in composite views. Links between source channels and destination channels which are effected by the cross-point switch are displayed by a visual indicator at the intersection of the selected source and destination stripes in the single plane view. In the multi-plane view, closed switches in their respective planes are represented by color coded segments of the visual indicator. Sources and destinations are linked and unlinked by selecting on the display the appropriate cross-point, or by designating a source and destination through selection of icons at the ends of the source and destination channel lines.

  • Patent number: 6354433
    Abstract: An article of manufacture for storing a razor comprises a cap such as for a shaving cream container having a wall section in which are integrally molded two spaced apart arms that are pivotable about integral living hinges out of the wall section to form a yoke in which the razor is suspended. The two spaced apart arms can have separate base sections with separate living hinges or a common base section with a common living hinge. Where the cap has a cylindrical side wall and a generally flat end wall, the two spaced apart arms can extend from a living hinge in the side wall along the side wall and into the end wall so that terminal sections of the arms form an angle with the base sections. Alternatively, the arms can be formed entirely in the side wall, and if desired, have the terminal sections project toward one another to form a reentrant opening for retaining the razor.

  • Patent number: 6270472
    Abstract: Apparatus and a method for depositing multiple implants carrying radioactive isotopes, pharmalogical agents or transgenes, in soft tissue including tumors and organs with precise, selectable spacing between implants includes an introducer in the form of a tube which is inserted into the soft tissue and an obturator for pushing implants out of the introducer one at a time. An operating mechanism incrementally withdraws the introducer while the obturator remains stationary thereby depositing a single implant. The obturator is then coupled to the introducer for the remainder of the stroke to provide the spacing. In a preferred embodiment, the introducer is resequenced to lay down parallel rows of implants. An indicator records the total number of implants deposited. The distal end of the introducer is configured to retain the implants and allow them to be discharged into the soft tissue singly.

  • Patent number: 5697422
    Abstract: A vacuum die-casting machine has a sprue cavity with sufficient depth facing the shot cylinder that the shot cylinder piston can easily crush with a pressure of less than 1000 psi the thin cylindrical shell of solidified metal which develops into the biscuit, and continue to advance after the die cavity becomes fried with molten metal to inject additional molten metal into the die cavity to make up for shrinkage porosity as the cast part cools. The runner through which the molten metal passes from the sprue cavity into the die cavity has generally spherical reservoirs adjacent circular gates to further assure the supply of the additional molten metal to make up for shrinkage in the part. In addition, the piston can be oil cooled steel to delay formation of the biscuit.

  • Patent number: 5435373
    Abstract: The fill chamber bore of a die-casting machine is lubricated and prepared for casting by inserting an elongated member into the die-end of the bore while spraying with lubricant. During withdrawal of the elongated member, a conical spray of gas directed toward the die-end drys the lubricant and sweeps vapor and flash, or solder, out of the die-end. The elongated member is preferably a flexible carrier which is guided between the bore and a path between the open die halves lateral to the bore. The lateral path is perferably defined by a tubular member supported by a vertical carriage mounted on a vertical mast for alignment of the flexible carrier with the fill chamber bore when the dies are open. The vertical mast can be mounted on a horizontal carriage moveable along a horizontal bore to preclude interference with normal operation of the die-casting machine.

  • Patent number: 5408178
    Abstract: The surface or internal structure of diamagnetic and paramagnetic materials is imaged by measuring, preferably with a superconducting quantum interference device (SQUID) magnetometer, perturbations to an applied magnetic field resulting from variations in magnetic susceptibility at an array of locations across the object. The array of perturbation measurements is processed to generate a map of local susceptiblities. For implementation of susceptibility tomography, multiple arrays of perturbation signals for a plurality of relative orientations between the object, the field, and the measurement locations are processed to generate values for local susceptibility at selected sites within the object, such as along a selected sectional plane.

  • Patent number: 5358130
    Abstract: A one-piece closure for dispensing product from a container has a cap secured to the container and a lid connected to the cap by a support arm through an integrally molded hinge. The support arm is pivoted by the hinge between a pair of upstanding projections on the end wall of the cap. Ribs projecting laterally from the support arm engage the projections to maintain the lid opened when the container is inverted to dispense product. When the lid is pushed closed, the ribs deform to allow the support arm to pass between the projections. In one embodiment, side edges of the ribs engage upwardly facing cylindrical camming surfaces on the projections. In another embodiment, the outer surfaces of the ribs engage confronting flat surfaces on the two projections. In the closed position of the lid, the ribs in both embodiments are received in recesses in the projections so that they do not become permanently deformed and loose their effectiveness over time.
