Abstract: A blind device for use in concealing a user from view during the course of hunting or observing wild geese includes a shell goose decoy mounted on a support structure that supports the shell in an elevated, generally horizontal position above the ground to provide a substantially unobstructed space below the shell to accommodate and conceal at least a portion of the user's body, and enables the user to swing the shell with generally horizontal movement about a generally vertical offset pivot axis of the support between a covering position in which the shell overlies and conceals the user and a revealing position in which the shell is swung out of the way to one side of the user, providing the user with substantially unobstructed overhead viewing and freedom of movement.

Abstract: A head trimmer machine for cutting off excess material from a cylindrical portion of a blow molded bottle includes a fixture, a spindle rotatably mounted in the fixture, a cutting head attached to the spindle for rotation therewith, a cutter mounted to the cutting head, and a vacuum source for collecting the trimmed material by suction. The cutting head has a central passage so that it can fit down over the head of the blow molded bottle. The cutter is supported in the cutting head for movement between retracted and extended positions. In the extended position, the cutter extends into the central passage of the cutting head to cut the head or other excess material from the neck of the bottle as the cutting head turns. The spindle includes a central passage aligned with the central passage of the cutting head and the excess material is removed by being drawn through these passages by a gaseous flow created by the vacuum source.

Abstract: Fluid compressor or expander having a main rotor with discrete arcked-helical flutes that have ruled surface roots that match the predominantly planar tips of the teeth of the associated gate rotors and provide effective fluid sealing as the gate rotor teeth sweep through the flutes of the main rotor during compressor or expander operation. The flutes can be readily and economically made by end milling, in which a first flute is milled with a minimized number of milling passes such as a first pass to make one arcked-helical flank and a portion of the arcked-helical root of a first flute and a second pass to make the opposing arcked-helical flank and another portion of the arcked-helical root of the first flute. Additional discrete flutes are made in a similar manner until the main rotor is completed.

Abstract: Described are molds, dies and forming tools comprising: a) a heat exchanging body support member; and b) within the support member, a molding cavity portion formed by thermal spraying metallic particles to a desired configuration in the support member. Also described are methods of making a mold, die or forming tool comprising the steps of: a) providing a body support member having a controlled and designed porosity which permits the enhancement of the heat transfer ability of said mold, die or forming tool; b) configuring a surface of the support member to a desired cavity; and c) spraying particles to the configured cavity in the support member, thereby producing a mold, die or forming tool. Preferably, the materials of construction are metallic and are applied by thermal plasma spraying. The particles may also be ceramics, metal matrix composites, ceramic matrix composites, thermoplastic resins, thermoset resins, and composites based thereupon.

Abstract: A method of converting, on a single line printing press, two webs of material into individual rolls of ribbons of dual-layered, peelable-bonded-together lids. Each lid has a peelable, overlying lid formed from one of the webs and an underlying lid formed from the other web where these lids are created by die cutting the two webs while bonded. Also, one of the lids has dispensing holes and the other lids is printed with selected indicia and/or logos. The ribbons are wound in multiple layers around cores for shipment to processors of food particles, such as salt or cheese, to be secured to individual, cup-like containers.

Abstract: A method of molding a shaped article includes the steps of providing a molding tool having an exposed surface for receiving a plastic powder resin to be melted thereagainst and an insulated surface; providing an insulating panel with insulated laminated alternating layers of fiberglass and silicone rubber and an inner core filled with silicone rubber and a plurality of hollow glass beads to prevent melting of plastic powder resin on the insulated surface; applying a plastic powder resin on the exposed mold surface and melting it thereon while exposing the insulating panel to the plastic powder resin remaining in powder form thereon for reclaiming and thereafter setting said melted plastic into a plastic article by cooling the plastic article and removing it from the molding tool.

Abstract: A system for moulding containers in thermoformable and heat-weldable material. The system includes a heating and welding station and a forming and shape-stabilizing station, with at least one welding and forming station in-between, producing progressive forming and shape-stabilizing of the containers.

Abstract: A water treatment method and apparatus is described for generating a supply of activated water containing oxidants, including hydroxyl radicals, hydrogen peroxide, and hydroperoxy radicals, but excluding ozone. The apparatus includes a generator having ultraviolet lamps to which air is exposed to create activated air. To suppress the generation of ozone in the activated air, the air subjected to the ultraviolet lamps is maintained at a relative high humidity. Also, the activated air is generated in the presence of a catalyst and using 254 nm light, both of which are believed to aid in the destruction of any ozone generated by the exposure of the air to other wavelengths of the uv light. The catalyst also provides additional oxidants in the air. The activated air is entrained in the water using an injector to thereby produce the activated water.

Abstract: A furniture product with a leg supported frame has transversely spaced apart tubular side rails with slotted openings in wall faces thereof for receiving the sling edge loops of a web sling which spans the rails to support the weight of a furniture occupant. The side rails have rod-like members, of a cross-sectional configuration larger than the slotted openings, extending through the loops, to retain the loops within the rails. The sling loops include a synthetic plastic fabric core sheet provided with synthetic thermoplastic coats on each side, the core sheet edges forming the loops extending into the slotted openings and around the rod-like members, and then back out the slotted openings to positions terminating in heat welded seam folds of double core sheet thickness lying upon and braced by the rail wall faces.

Abstract: A flat-sitting bottom end closure for liquid filled, thermoplastic-coated paperboard containers, and mechanism for forming same. The mechanism includes an indexible rotor having a plurality of mandrels on which tubular container blanks are mounted, wherein each mandrel has an end cap defining a configuration which, in conjunction with a complementary pressure pad, produces four flat corner portions or pedestals on the container bottom end closure when confined between the pressure pad and each end cap.

Abstract: A gear-reducing, torque-multiplying gear drive assembly having a housing journaling coaxial input and output shafts coupled by an orbital gear drive assembly. A driving sun gear is fixed on the input shaft and rotates a plurality of input planet gears fixed to associated planet shafts journaled at their opposite ends by end walls of a rotary cage within the housing. Each planetary shaft also has an output planet gear within the cage enmeshed with a stationary sun gear fixed to the housing. Rotating the input shaft rotates the planet gears which in turn rotates the cage and drives the output shaft. Selecting the output planetary gears and stationary sun gear to be twice the size of the input gears produces a 2:1 gear ratio between the input and output shaft with a resultant 1:4 torque ratio.
