  • Patent number: 6286732
    Abstract: The invention in the simplest form is a dispenser valve with an increased flow capacity. The device is particularly suited for dispensing liquids, and has a plurality of individual thin and streamlined elevated standoffs that serve as the spring seat, lowering flow losses and providing a larger flow path area or particulate matter included in the liquid. In addition, the ball check valve chamber is funnel shaped, creating an efficient flow for the dispensing liquid regardless of the viscosity or particulate of the liquid. The unit increases discharge capacity, reduces clogging, improves efficiency, and allows the unit to dispense highly viscous and gritty materials.

  • Patent number: 6284312
    Abstract: A method and apparatus, and product by process, for the production of bulk polysilicon by broad area chemical vapor deposition, consisting of a quartz envelope and base plate forming a reactor enclosure, with external radiant heaters providing the heat source. A thin wall, edge-defined film fed growth (EFG) silicon tube section is used as the deposition casing and reaction chamber wall. The tube is capped at the top and sealed to the base plate to form the reaction chamber. External heaters radiate heat through the quartz enclosure to heat the tube wall to deposition temperature. A through flow of process gas is introduced to initiate the deposition. A uniform wide surface area deposit occurs on the inside surface of the tube, causing the diameter to become increasingly smaller as the yield accumulates.

  • Patent number: 6262652
    Abstract: A public pager messaging system with publicly accessible pager readout terminals distributed throughout the messaging system range, where each pager terminal is preprogrammed to recognize one or more specific capture codes that may be appended to a message, and to then accept and hold only those messages. A sender can create and append to a message either or both of a message code for one or a class of intended recipients, and a capture code consistent with the areas in which the recipients are likely to be found. The message code acts as a security lock on the message, making it inaccessible by recipients unless or until the necessary information about the message code is shared by sender with the intended recipients, so that the lock can be opened. The message may be accessible on multiple pager terminals. The message may be erased if not accessed within a preset time.

  • Patent number: 6231923
    Abstract: A method and apparatus for producing a coating or a near net shaped monolithic ceramic part by chemical vapor deposition, where the resultant coatings or parts consume less deposit material and require less machining. Mandrel substrates are closely designed for producing a specific, near net shaped final part, including negative relief features. Several of the mandrel substrates are mounted through centers in a spaced relationship on one or more rotable shafts as tooling for a chemical vapor deposition furnace. The tooling is installed in a chemical vapor deposition furnace so that the shafts are oriented perpendicular and the substrate planar surfaces are parallel to the flow pattern of reactant gases through the furnace. The shafts are rotated during the deposition process so that the mandrel substrates each receive a uniformly distributed ceramic deposit in the near net shape of the final part.

  • Patent number: 6209567
    Abstract: A foam trap or FOB for a gas propelled or mechanically pumped liquid dispensing system, having an upper ball stopper valve seat and gas vent port at the top and a lower ball stopper valve seat and liquid outlet port at the bottom, with two floating ball stoppers that are raised and lowered by the level of liquid unless locked into a seated position on a valve seat by pressure. Ball stoppers can be independently mechanically dislodged and constrained from reseating on either valve seat by externally accessible means. The interior geometry inhibits the ball stoppers from competing or blocking access to respective valve seats when liquid is falling or rising. The trap automatically shuts off outflow when liquid is depleted, permitting a container change, opening of the vent port, and purging of gas or air in the trap by refilling the trap with liquid before closing the vent port and reopening the outflow. The trap may be integrated into an automated container switching system for liquid dispensing systems.

  • Patent number: 6170685
    Abstract: A foldable, electrical box kit for on-site assembly and installation in wallboard, with at least two opposing panels each having a pair of spaced apart front face flanges and respective, laterally centered on the panel, center-bored, retaining screw and rotating retainer clip assemblies. The unfolded box is configured with living hinge lines to permit easy folding and snap assembly of adjacent sidewall edges to form a rigid enclosure. Retainer clips are retracted by their retaining screws into clip slots in the panels for clearance. The box is inserted through wallboard as far as the front face flanges permit, then the retaining screws are rotated, the first quarter turn of which rotates their respective retaining clips from the retracted position to an extended position behind the wallboard. Further clockwise rotation of each screw brings its retaining clip forward into a firm, three point grip with its respective pair of flanges on the wallboard.

  • Patent number: 6162199
    Abstract: A hand held device for loading a hypodermic syringe from a medicine vial is configured for easy placement of the syringe into a closely conforming channel in the proximal end of the device, with the needle end pointing towards the other end. The other end of the device is configured for easy placement of a standard vial into a closely conforming chamber with its penetrable cap facing the needle tip. Closing the device causes or permits the further action required for piercing the vial with the syringe needle. A sliding pull tab engages the syringe plunger so that gripping and pulling on the tab withdraws the plunger from the syringe, thus drawing fluid from the vial. An amplified or enhanced readout capability visually indicates the dosage of fluid withdrawn from the vial. An auxiliary needle mounted so as to be slightly offset from the syringe, provides for a supplemental piercing of the vial so that make-up air is available when large dosages are drawn from the vial with a single pull of the plunger.

  • Patent number: 6155656
    Abstract: A slide bar for snowmobiles has sinusoidal grooves running lengthwise on the sliding surface that open at the aft end of the slide bar for drainage. The sinusoidal grooves retain packed snow accumulated during operation over snow-covered terrain, until the packed snow absorbs sufficient heat to soften and pass through the recurving path of the grooves. The retention characteristic of the sinusoial grooves for holding packed snow provides extended lubrication and cooling to the slide bar and track when the snowmobile leaves snow covered terrain to cross intermittent stretches of bare ground.

  • Patent number: 6067728
    Abstract: An apparatus and method for drying a microelectronic structure on wafer substrate using supercritical phase gas techniques and a unique pressure vessel locking mechanism. There is lid and a base with an open cavity to contain at least one microelectronic structure on wafer substrate. Clamping the lid to the base uses locking clamp rings with open jaws large to partially enclose the edge of the vessel. The clamp rings are supported symmetrically about the sides of the vessel. The rings are adjusted between an open position where the rings are clear of the vessel and a locking position where the jaws partially enclose the vessel. The jaws and the vessel share a tapered cam plate and roller system configured to bring the rings into vertically compressive locking engagement on the pressure vessel when the rings are moved into locking position. Mechanical interlocks provide security against back pressure opening the rings.
