  • Publication number: 20030035896
    Abstract: A method of controlling drying stresses through controlled shrinkage of a ceramic coating coated onto a substrate. The method first includes applying a non-cured ceramic coating onto the substrate and permitting the coating to dry until a mechanically stable outer surface layer of the coating is formed. Once this layer is formed, a drying control is applied in a quantity sufficient to penetrate into the surface layer, with the result of such application being the inhibition of formation of a dry outer skin as continued drying is permitted to occur. Once such drying is complete, the outer surface layer is subjected to an elevated temperature for curing and for evaporating therefrom the drying control agent to thereby produce a cured-ceramic coated substrate whose coating is void of large cracks and whose durability is beneficially opportune.

  • Patent number: 6390010
    Abstract: An anchor includes at least one fluke, a shank, and a float. The relative position of the float with respect to the center of gravity of the combined shank and fluke causes the anchor to assume a generally upright orientation quickly once the anchor is dropped in the water. One end of the shank is attached to the fluke and the float is attached to a rearward portion of the shank, with the float's center of buoyancy spaced away from the connection to the fluke. Upon being put in the water, the anchor quickly assumes a generally upright orientation, i.e., shank up and fluke tip down. Once in the generally upright orientation, the anchor may gently rock side to side with a pendulum-like action, with the tip of the fluke preferably being the lowest point of the anchor, during its descent to the bottom.

  • Patent number: 6243274
    Abstract: A plurality of shields is provided for shielding selected electronic components and electronic sub-assemblies mounted on a printed wiring board assembly from electromagnetic interference (EMI) and/or from radio frequency interference (RFI). The shields include open-ended electrically conductive casings having lower ends fixedly attached on the printed wiring board so as to surround selected components. A compliant electrically conductive member is positioned in common over upper ends of the casings. An electrically conductive housing disposed over the compliant member provides compression of the compliant member such that electrical contact is maintained between the housing on the upper ends of the casings. A grounded base plate is spaced from the wiring board assembly. The housing is removably attached to the base plate to provide the plurality of shields.

  • Patent number: 6228200
    Abstract: A belt press uses differential thermal expansion between parts of a platen assembly to generate pressure. The belt press typically includes substantially aluminum platen assemblies that are connected such that movement of the second press surface away from said first press surface is limited. A plurality of expansion limiting rods are aligned generally parallel to the top platen's longitudinal axis and attached thereto. The expansion limiting rods preferably are attached via adjustable couplings to sturdy anchor bars laterally disposed across the platen and rest against two or more bridging rods midway along the length of the platens. The expansion limiting rods have a coefficient of thermal expansion that is smaller than the coefficient of thermal expansion for the platens.

  • Patent number: 6105505
    Abstract: The present invention is directed to a hard target incendiary projectile that includes a penetrator casing filled with an incendiary and having a rear opening sealed with a closure. When the projectile hits a target and penetrates, a fuze ignites the incendiary. Hot gasses from the burning incendiary increase pressure within the casing so that within milliseconds of the fuze firing, pressure within the casing ejects the closure out of the rear opening with a vigorous pressure pulse that expels burning fragments of incendiary into the interior of the target. The projectile can also carry additional payloads such as chemicals, radioactive materials, and electric/electronic devices that can be ejected from within the casing into the target. The projectile can also be configured so that pressure within the casing opens vents in the closure but does not eject the closure. As the incendiary combusts or reacts within the casing, hot reaction products are vented through the vents into the target.

  • Patent number: 6041731
    Abstract: An anchor includes at least one plow-like fluke, a shank, and a float. The relative position of the float with respect to the center of gravity of the combined shank and fluke causes the anchor to assume a generally upright orientation quickly once the anchor is dropped in the water. One end of the shank is attached to the fluke and the float is attached to a rearward portion of the shank, with the float's center of buoyancy spaced away from the connection to the fluke. Upon being put in the water, the anchor quickly assumes a generally upright orientation, i.e., shank up and fluke tip down. Once in the generally upright orientation, the anchor may gently rock side to side with a pendulum-like action, with the tip of the fluke preferably being the lowest point of the anchor, during its descent to the bottom.

  • Patent number: 5974935
    Abstract: An apparatus for variable length belt splitting includes a stepwise feeder which urges the belt, such as conveyor belt, forward in discrete steps and a reciprocating cutter disposed downstream from the feeder. The feeder preferably includes both a holding clamp and a feed clamp that is connected to, and is moved with respect to, the holding clamp by a feed actuator. The cutter preferably moves parallel to the holding clamp and is moved back and forth by a bi-directional ram. The cutter splits the belt edge to edge at a predetermined depth in length increments corresponding to the feeder's step length to a total length determined by the user. Optionally, the feeder and cutter are connected to a support structure which allows the feeder and cutter to be placed at an angle with respect to the path of the belt through the machine, thereby allowing for diagonal splits to be made with respect to the longitudinal axis of the belt without stewing of the belt.

  • Patent number: 5083247
    Abstract: The invention relates to lighting systems, for fishing rods, which are useful for proper handling and managing of such rods under poor ambient lighting conditions. The lighting system directs light substantially in line with the fishing line and the eyelets on the pole part of the rod, without obstruction, so that all eyelets and the line therethrough may be clearly lighted. In addition light can be directed to the line exit side of the reel, mounted on the handle part of the fishing rod, to assist in untangling or rethreading the line through the reel line guide. The lighting system is also useful for other tasks to be performed under poor ambient light conditions.

  • Patent number: 4084274
    Abstract: A turning bed which can be tilted mechanically to turn the occupant from side to side, comprising a tilting assembly pivotally secured to a bed frame of known type. The tilting assembly consists of a mattress frame longitudinally divided into at least three parts: a center section with an outer section(s) pivotally connected adjacent each longitudinal side of the center section. The pivotal connection is such that when the center section is tilted, the outer section(s) adjacent the raised side of the center section is/are tilted as one with the center section, and the outer section(s) adjacent the other side of the center section pivot(s) relative thereto. The center section is pivotally supportable from the bed frame, and can be tilted by a lever secured at one end to the center section, the other end of the lever being moveable (by suitable means such as a screw-and-nut arrangement) to tilt the center section.

  • Patent number: 4020643
    Abstract: Ice confections are extruded through a multiplicity of holes. Unevenness of flow during extrusion is reduced. The holes can be arranged in an array to determine the cross-section of the extruded ice confection. Extruded ice confections can be readily prepared with, in cross-section, very fine detail e.g. key-shaped, or heart-shaped or containing air passages.
