Abstract: A paintball feed system (10) comprises flexible detent beams (32a,b) that flex about first and second support points (33,34) such that they allow a paintball (22a) to pass from a hopper (18) into a feed tube (12) leading to a paintball marker's breech (16) under it's own weight when flexing about the first support point (33). The beams (32a,b) are rigid enough, when flexing about the second support pint (34), to prevent the return of the paintball (22a) back into the hopper (18) from the feed tube (12).

Abstract: A paintball container comprises a body 12 and a lid 14. The lid 14 is hinged to the body 12 at one side, and has a tab 42 at the other side to facilitate opening of the container. The body 12 has a guard 26 formed on it adjacent to the tab 42 on the lid. The guard is substantially U-shaped and bounds a recess 30 into which a user can insert their thumb to pull up the tab 42 to release the lid. The guard 26 prevents accidental opening of the lid, for example when the container is being removed from a harness in which it is being carried.

Abstract: The present invention includes a baby bottle liner constructed and arranged to fit into a cavity of a baby bottle. The baby bottle liner includes a continuous, profiled, elongated reclosable fastener. The continuous, profiled, elongated reclosable fastener has a first continuous elongated profile strip and a second continuous elongated profile strip. The first continuous elongated profile strip and the second continuous elongated profile strip are dimensioned to provide an airtight and/or watertight seal upon interconnection thereof. The baby bottle liner further comprises an airtight and watertight side seal at each end of the reclosable fastener. Each side seal connects an end of the reclosable fastener to an inside surface of a front wall and an inside surface of a back wall of the liner. The invention also provides a baby bottle with a baby bottle liner and a kit for infant nursing that has a plurality of baby bottle liners.

Abstract: A food dispensing apparatus is provided having an aluminum housing with an opening at its top surface, a cover for the opening, an outer enclosure disposed about the housing, a bag of food product disposed within the housing, a manually operated valve attached to a first end of the food bag and in fluid communication therewith for dispensing the food product, a bladder connected to a source of pressurized air and disposed within the housing for compressing the bag of food product for selective dispensing from the apparatus and a heating mechanism contained within the housing for inductively heating the food product for use.

Abstract: A solar heating device which indicates the proper window covering status for maximum energy conservation. A support structure (18) rests on window sill (16) and suspends two thermistors (22 and 24). One thermistor (22) is supported on the room side of drapery (12) and the other thermistor (24) is supported between drapery (12) and a window (14). When the net heat flow is inward from outside the room, thermistor (24) near window (14) will be warmer than room side thermistor (22). When this occurs, the temperature dependent resistances of thermistors (22 and 24), voltage divider resistances (30 and 32), and a comparator (36) turn on a light emitting diode (28). This indicates that drapery (12) should be opened to let solar radiation in to heat the room. Otherwise, drapery (12) should be closed to conserve the existing heat in the room.

Abstract: A workpiece support apparatus is provided with a pair of pivotable leg assemblies which are movable between a first, open position, and a second, closed position. A releasable latch member is provided for holding the leg assemblies in a selected one of the open and closed positions. The apparatus includes a vertically adjustable work support assembly which can be locked at a desired height.

Abstract: An improved needle guard for a syringe is provided having a tubular body. The needle guard includes a longitudinal bore and one or more slots or slits formed therein. The longitudinal bore of the guard is sized for telescopic reception of and contraction about the tubular body of the syringe. Slots or slits are arranged so as to allow deformation of the longitudinal bore of the needle guard thereby increasing the inside diameter of the longitudinal bore so as to allow axial movement of the needle guard along the tubular body of the syringe.

Abstract: A simplified automatic car wash system is disclosed which comprises a linear trolley suspended from the upper structure of a car wash building and a cross trolley transversely mounted thereto. A spray arm is rotatably mounted to a glider plate on the cross trolley and the spray arm is used to deliver soap and water to an automobile. The spray arm is the only cleaning apparatus utilized, there being no need for rotating brushes and the like. As such, the only elements which come and in contact with the automobile during a car wash, are soap and water.

Abstract: A silver colored metal alloy having improved tarnish resistance is disclosed, which is intended primarily for solid sterling jewelry and utensils and may also be used in silver plating, and does not easily tarnish and corrode. The alloy consists essentially of 80% to 92.5% silver, 4% to 9% palladium, 0% to 10% copper and 0.5% to 1% indium or zinc.

Abstract: The present invention provides an improved casting alloy for use in costume jewelry and jewelry samples. In accordance with the present invention, a gold colored metal alloy is disclosed which is tarnish resistant and consists of the following ingredients such as, 75 to 85% copper, 5 to 15% nickel, 0 to 12% indium, and 0 to 12% zinc. It is also desirable to add approximately 0.01% iron and/or 0.05% silicon to act as a grain refiner and fluidity enhancer respectively. The alloy in accordance with the subject invention is a rich gold color which approximates a fourteen carat alloy. In addition, tarnish resistance and workability is greatly increased.

Abstract: An electrical guitar is provided having a conventional guitar body, strings and mounting bridge for the strings. A manually rotatable disc is rotatably mounted on the guitar. On the rotatable disc are one or more electromagnetic pick-up heads which allow the pick-up heads to be rotated to a number of desired positions. The rotatable disc may be selectively fixed on each position by a brake or by friction. The pick-up heads are constructed to remain electrically connected to an amplifier during rotation. In addition, the rotatable disc is sized and positioned to facilitate easy, manual rotation thereof during performance by the musician.

Abstract: A psyllium composition in tablet form is provided having a wetting agent, a disintegrant and a binding agent. In one embodiment, the wetting agent is polysorbate 80, the binding agent is polyvinyl pyrrolidone and the dry binding agent and disintegrant is microcrystalline cellulose. Calcium carbonate may also be added to serve as a disintegrant in HCL. The tablets are manufactured by mixing the psyllium powder with a solution of povidone and polysorbate 80. Microcrystalline cellulose may be added either during or after granulation. After mixing, the composition is compressed into tablet form. The mixing of the ingredients in specific quantities allows a tablet to be manufactured that is both resistant to fracture and at the same time disintegrates easily and quickly in the gastrointestinal tract of the patient.
