Abstract: A process for extracting and analyzing virtually any sample which may be contaminated with pollutants, toxics or other impurities. The process can be used to extract and analyze one contaminant, such as a volatile compound (gasoline), or the process can be used to extract and analyze several contaminants, including both volatiles and semi-volatiles. The process comprises a vacuum extraction technique followed by a heating/cooling cycle comprising a series of heating and cooling stages.

Abstract: A rotary lawn mower adapted to be moved over a surface to mow vegetation; said lawn mower includes a mower deck, a motor, rotary cutting means and a push handle assembly; said mower deck including a top portion adapted to support said motor and downwardly extending edge portions; said motor being affixed to the central portion of said mower deck and coupled to drive said rotary cutter means positioned underneath said mower deck substantially parallel to said surface, said push handle assembly having telescoping or pivotal members and being pivotally attached to the deck such that the push handles may be folded over said motor and attached to said mower deck forward of the motor thus permitting a user of said mower to selectively grasp said push handle assembly to lift and move said rotary mower from one location to another.

Abstract: An air grain conveyor comprising a means for generating high velocity air, a grain ejection section, a connection between said means and said ejector section whereby the high velocity air is ejected into the ejection section, and a grain hopper attached to the ejector section whereby grain is drawn into the ejector section and conveyed to a discharge section wherein the velocity of air borne grain is slowed prior to deposit of the grain into a receiver.

Abstract: The present invention relates to method and apparatus for treating waste water, particularly metal-containing waste water. The process includes separating and removing metals and other impurities from the waste water by the sequential addition of a base, a polyelectrolyte and an acrylamide-containing copolymer dispersion. The purified water is recycled for continuous reuse while the small quantities of metal-rich residue are available for reclamation.

Abstract: An shellfish shucking machine comprising a housing; means on the housing for supporting oyster shells; a tool on the housing for opening oyster shells; and means for operating the tool whereby the tool performs a cutting of the oyster shell and then a splitting of the oyster shell.

Abstract: A rotary stripper tool comprising a housing; a motor supported on the housing; a shaft supported in the housing; a cutter head supported on the shaft; a drive between the motor and the shaft for rotating the cutter head; guides on the shaft; a vacuum supported on the housing for removing dust and shavings from the work area; and hand supports for the tool.

Abstract: A decorative waterfall comprises a housing having a top and bottom and a front and back wall; a reservoir for water in the bottom of the housing; a reservoir for water at the top of the housing; a pump for conveying the water in the bottom reservoir to the top reservoir, whereby the water overflows the top reservoir and flows down the front wall; and at least one indenture for creating a sound resembling the sound of a natural waterfall.

Abstract: An improved window screen in which each strand of the screen is substantially totally transparent is disclosed. In all cases the screen comprises a plurality of optically transparent strands with selected strands intersecting at an angle to form the screen. The strands may be woven or the strands may be bonded at their intersections to form the screen. Light passes through the strands in a distortion free manner. The strands of the screen may either be conventional optical fibers or merely of transparent plastic.

Abstract: A rotary lawn mower adapted to be moved over a surface to mow vegetation; said lawn mower includes a mower deck, a motor, rotary cutting means and a lift handle assembly; said mower deck including a top portion adapted to support said motor and downwardly extending edge portions; said motor being affixed to the central portion of said mower deck and coupled to drive said rotary cutter means positioned underneath said mower deck and substantially parallel to said surface, said lift handle assembly, being selectively positioned on at least opposed sides of said motor means and adapted to be attached to said mower deck thus permitting a user of said mower to selectively grasp said lift handle assembly to move said rotary mower from one location to another.

Abstract: An internal combustion engine is provided with water injectors and a source of pressurized water having at least one injector valve operated by a computer which senses various operating conditions of the engine and in response to said conditions opens or closes the injector valves allowing or blocking the passing of high pressure water into the combustion chamber.

Abstract: A double face seal for coke ovens comprising charging and venting tubes having flanges; charging and venting ports having top surfaces; and sealing means attached to the flanges for engaging and sealing the top surfaces during charging and venting of coke ovens.

Abstract: An animal defensive barrier device comprising a hand-grip portion having end caps; a strap connected to the hand-grip through one of the end caps; a loop portion distal at one end of the hand-grip and a loop portion distal from the first loop end; a plurality of knots between the hand-grip and the distal loop portion; and a plurality of sleeves on the strap between the hand-grip portion and the distal loop portion.

Abstract: A cartridge clip loading/unloading device comprising a base; a post on the base having a terminal end; a clip having slots supported on the post at the terminal end; a tool having a first arm supported for rotation on the post; and a second arm having means for pressisng cartridges onto or out of the clip.

Abstract: A recreational area construction comprising a base having depressions and rises thereon; a plurality of borders forming a perimeter around said base; strips of water pervious material on the base and lining the depressions, and having their ends overlapping whereby water flows laterally across the strips toward the borders; an end of one of said strips extends beneath and beyond said border whereby water is conveyed away from the said area; and a top layer of cushioning material supported on the base and water pervious material.

Abstract: The described invention is intended for use primarily in the yacht repair industry and specifically in the repair of fiberglass hulls of yachts. However, its use will not be limited to fiberglass in yachts but fiberglass in general where applicable.The invention removes gelcoat (coating over fiberglass) and/or consecutive layers of fiberglass laminate.The invention is specifically designed to remove osmotically blistered gelcoat and/or fiberglass laminate in an efficient and in an environmentally attractive fashion.The invention "planes" off gelcoat and/or fiberglass laminate duplicating the existing contour of the hull or boat bottom. The cutterhead is continually flushed with water to prevent toxic dust from being released into the air. Interchangeable depth gauges allow change in the depth of the cut. Gelcoat and fiberglass are removed anywhere from a 0 to 1/4 inch depth at a rate of four square feet per five minutes leaving a consistent and fair surface.

Abstract: A recreational area construction comprising a base with a plurality of borders forming a perimeter on the base; a layer of water pervious material on the base between the borders, and a top layer of cushioning material supported on the base and layer of water pervious material.

Abstract: This invention relates to a method and apparatus for preventing the fast-forwarding of a video tape cassette through a commercial advertisement recorded at the beginning of the tape. The methods disclosed make use of the standard photoelectric circuitry normally built into a video cassette recorder for sensing the transparent ends of a tape and stopping the recorder. Actuation of the standard stop circuitry may be accomplished by adding an auxiliary light source and associated operating circuitry to illuminate the photocell thereof.
