Abstract: This invention is a box-like device to reproducibly roll a soil sample into a 1/8 inch thread while at the same time drying the sample and comprises a flat base with 1/8" high side rails and a slideable top plate that slides on these rails. About a 2 gram soil sample moistened so that particles of the soil adhere to each other is rolled on water absorbent paper on contact surfaces of the unit and at the point that sections of the rolled thread break apart the percent water is determined and this percentage is the soil plastic limit.

Abstract: A fuel assisted electromagnetic launcher wherein a payload is contained in a forward portion of a pointed cylindrical launch container and rocket fuel is contained in a rearward portion; and wherein a launch preparation unit in the launcher cools and heats alternate junctions in circular disposed thermopiles around the cylindrical launch container; and wherein electrical coils encased in plastic form a cylindrical barrel. With the coils with spacers in between each containing a photoelectric detector charged by an external D.C.

Abstract: An automotive fluids dispensing and blending system wherein a customer may select various fuel additives such as octane enhancers, fuel injector cleaners, varnish dissolvers, compounds to free-up piston rings, etc., all choices of which may be automatically blended with the selected fuel as the fuel is being dispensed normally into the vehicle fuel tank. The system also allows the customer to select and dispense various engine oils and oil additives, antifreeze solutions, windshield washer fluid, power steering fluid, and other automotive fluids directly into the vehicle using provided lines, nozzles and controls. All sales transactions are displayed to the customer and station operator for purposes of payment, and all sales transaction data is recorded and stored.

Abstract: This Hazardous Waste Reclamation process pyrolyzes hazardous waste such as PCB (polychloro-biphenyl) in a closed system in a molten alloy, containing some aluminum, at a minimum of 800 degrees C. to form activated carbon that is recovered from the circulating exit gas stream and an impure alloy ingot containing unreacted metals and metal salts that are saleable to a metal processor as a high grade ore. The composition of the alloy may be varied to assure maximum reaction to nontoxic alloy salts that remain in the ingot.

Abstract: A multifunctional basketball game monitoring unit that allows automatic scoring taking into account foul shots, and position sensitive shots and also allows scoring of shots missed with a programmable control processing unit allowing for a great variety of differing output statistics both to visual display and to a printer and also allowing a variety of audio choices as programmed or as entered on a keyboard to the controller.

Abstract: A dual function bidet and toilet bowl cleaner device using flexible tubing to tie directly into the tank water supply valve, into the tank, and into the suction of a pressure regulator valve feeding into dual spray heads through a pivotably attached arm that may be manually positioned from a retracted position under the rim of the toilet bowl to a position essentially centrally located in the toilet bowl; a simple plug cock valve may be positioned to activate one of the spray heads for use as a bidet and the other for use as a bowl cleaner.

Abstract: The disclosure describes an apparatus to use multiple expendable electromagnetically accelerated drill heads that are propelled into a electromagnetic accelerator that further accelerates the expendable drill heads to velocities as high as 30,000 ft./second to drill horizontal holes. Acceleration is achieved by making use of electromagnetic forces induced in a coil by opening a charged "ringing" circuit containing a capacitor interacting with magnetic poles around the expendable projectiles or drill head. Multiple accelerating coils, each charged by a D.C. source, are used while initial acceleration may be by interaction of electromagnetic fields between conductive rings on the drill head and induction coils.

Abstract: An economical steel roof truss for spanning large areas with unique shapes for maximum in use strength and splicing segments to use lengths that are easily handled and with a design to use minimum thickness metal consistent with loads and assembly costs.

Abstract: A shoulder rehabilitation device is described wherein the forearm is cradled in a movable lever on a mounting plate with the mounting plate hinged to a base plate in such a manner that the arm movement at various angles between horizontal and vertical exercises all the muscles in the shoulder; a structure of adjusting resistance to motion of the lever provides for prescribed exercise as the muscles strengthen.

Abstract: An infant changing board assembly sized to store in an unobtrusive upright position in an infant carrier and to be easily moved into a horizontal position to provide a flat changing surface without removing the baby from the infant carrier.

Abstract: A multi-functional mounting unit for a police car that removeably bolts to the floor in a front passenger section to rigidly hold a long barreled gun, communication equipment, flashlight, and miscellaneous articles; holding all without structural modification to the car.

Abstract: A battery powered rotary chamber pistol, suitable for firing 60 rounds per second of 22 caliber cartridges contained in a thin flexible belt without removing the cartridges from the belt.

Abstract: A portable hay feeder with open sides pivotally connected with angle brackets which are pivotally connected with roof rafters of the unit in such fashion that the sides will swing in an essentially vertical position as an animal pushes the sides against hay contained between the sides; spacer bar or rods forming vertical openings in the sides are properly spaced so that an animal may eat but the animal's head will not go between the upright space bars, thus the animals head pushes the sides inward allowing total consumption and minimizing waste.

Abstract: A glare shade for a rifle scope that may be manually removably mounted and is comprised of extensible sections containing light admitting apertures.

Abstract: A multi-purpose rotating membrane filter unit wherein the central portion of hollow filter discs covered with controlled pore size membranes communicate with the interior of the hollow rotating mounting shaft with the membrane surface of the rotating disc being kept clean by speed of rotation and, in some cases intermittent back flushing, and with filtrate draw off thru the hollow rotating mounting shaft.

Abstract: A dual valve assembly with calibrated or adjustable spring loading that may be attached to a valve stem on a tire to allow slightly over pressuring the tire with air and which then automatically adjusts the pressure in the tire to match a spring loading calibration.

Abstract: An ornamental sunglasses retainer comprising tubular stretchable material with the ends that fit over the sunglasses temple pieces treated with a stretch reducing prepolymer and threaded through either side of a manually releaseable friction catch and then pushed over the temple pieces of a pair of sunglasses into the hinges; there being sufficient length in some embodiments that by using the releasable friction catch the glasses may be held in any desired position from dangling around the wearer's neck to snugly against the wearer's head. Other embodiments include a flexible sun visor of foamed material attached to the tubular stretchable material of the retainer to added ornamental and utility.

Abstract: An air inlet and automatic pressure adjustment assembly comprising a smaller closed ended inner cylinder with a partially common wall with a larger outer cylinder with there being a vent hole in the common cylinder wall and an adjustable spring loaded to close vent valve in the inner cylinder so that excess air pressure opens this valve to vent air from the tire to the outside. The layer outer cylinder contains a normal air inlet valve that will be held closed by inlet air pressure of the tire.

Abstract: A replaceable part pallet designed to be assembled from two moldable shapes, one being a beam and the other being a slat with projections to extend through holes contained in the beams so that a single rod may be installed longitudinally through each beam and through projections on the slats to hold slats firmly fastened to three or more beams to form the pallet.
