Abstract: The method of compounding a high strength, cost-effective, composite of a high temperature, water sensitive, polar, polyamide-inide resin mixed with a talc, water absorbent/adsorbent filler. The method comprises raising said mixture to a temperature of about; 500.degree. F. to develop plasticity in said engineering resin. Thereafter there is added a lower temperature softening, water repellant, polypropylene resin and a compatibilizing additive. Finally all components are mixed in a mixing chamber sufficiently to obtain complete dispersion and homogeneity of the composite.

Abstract: Mixing apparatus comprising a pair of detachable, spaced rings,--one having inlet passages skewed in a direction to cause clockwise rotation of the exiting fluid, and the other skewed in an opposite direction to cause counter-clockwise rotation thereof, to cause shear action and intense mixing of fluid therebetween. Pairs of mixers may be arranged in different relative positions in either an open or closed body of liquid to effect mixing of effluent therein.

Abstract: A three sided, trapezoidal shaped storage container having an open front and housing three small, removable trapezoidal shaped storage bins for storing recyclable household water products such as glass, plastic, newspaper and aluminum cans. Said container has a hinged lid which, when in the closed position, provides a work bench area for chores related to recycling such as sorting and binding. In addition, said container has a pair of wheels and a pair of handles to provide a means of easily moving it around the yard.

Abstract: A process for producing spherical pellets from wet coal silt or also known as filter cake. The process involves mixing dry ash with the filter cake in a mixer. The blend thereof is discharged into a shallow pan disc pelletizer to produce pellets which are then coated in a reroll ring surrounding the disc pelletizer with more fly ash.

Abstract: A toothpaste dispenser having a chamber which is operated by a flexible bag extending longitudinally alongside the chamber. A one way valve is provided at the bottom of the chamber through which air, under pressure, is introduced when the bag is compressed manually. A toothpaste pusher inside the chamber is moved vertically upwardly by the air under pressure introduced through the one-way valve. The toothpaste pusher takes the form of a bellows.

Abstract: Method and apparatus for treating sulphur bearing coal comprising pulverizing the coal, mixing it with water, a reagent and free air and pumping the resulting mixture to a classifier to separate the coal from sulphur and clay, all at the mine site. The resulting pure coal slurry is then pumped to a plant site where it is mixed with acid and bacteria. The resulting slurry is pumped to a bacteria digester wherein it is recirculated to provide maximum contact of bacteria and coal, completing the removal of sulphur. The resulting slurry is introduced into a mixer wherein the bacteria is neutralized by a reagent, raising the pH above 7 to destroy the bacteria and simultaneously aerating the mixture to treat the effuent. The desulphurized coal is treated by drying apparatus to provide a final purified coal product.

Abstract: Apparatus for uniformly wetting and discharging ash. It is enclosed in a dust hood. It comprises an open top pan disposed at an angle of about 55.degree. degrees with respect to a floor, rotated at slow speed. An ash charge chute discharges ash into the pan. Fixed scraper means extend at right angles to the pan to scrape the bottom of the pan while water is sprayed onto the surface of the discharged ash so that the rotated ash is tumbled back to the bottom of the pan to effect uniform wetting of the tumbled particles as they are discharged downwardly from the top of the side of the pan.

Abstract: A needle cap holder of a syringe. It is of compressible material, such as rubber, having a central portion tapered inwardly from the top and bottom. It has a central, vertical cylindrical opening for receiving a needle cap of the syringe. It has a concave bottom portion.

Abstract: In a weapon subject to a sequence of high acceleration followed by high spin and including a detonator and an explosive charge; the improvement comprising a barrier having two parts located between the detonator and explosive charge to normally form an obstruction to prevent accidental detonation of the explosive charge by the detonator. Mechanical locking means are provided to lock the barrier in place, comprising a split cylinder and a spirally wound ribbon, a pair of pins restraining the outer surface of the ribbon to prevent premature unwinding. When the weapon is fired from a gun, the high acceleration will remove the pins and allow the ribbon to unwind. Upon unwinding the entire ribbon, the barrier under the action of spin, will be removed to provide an unobstructed path between the detonator and explosive charge.

Abstract: A can crusher comprising a container, a reversible motor mounted therein, a pinion gear driven by said motor and a gear driven by said motor and a gear of greater diameter driven by said pinion gear. A threaded shaft, having right hand threads on one side and left hand threads on the opposite side, is provided as the gear of greater diameter. A pair of can-crushing arms, one geared to the right hand threads and the other geared to the left hand threads, effects crushing of a can therebetween. A reversing switch is operated by one of the can-crushing arms after predetermined movement in the crushing direction to drive the arms apart.

Abstract: A motor home has a rear, extensible room portion that does not require ground support. The extensible room portion comprises a rear wall, roof portion, and a pair of sidewalls having integral top extensions extending over 40% forwardly of the extensible room portion and serving as lever arms.

Abstract: In apparatus for spraying water on granular material in a rotating cylindrical pan and for compressing the mixture into pellets. A moisture sensor on said pan provide a signal to a programmable computer controller for providing a constant moisture content on the surface of the pellets. In one embodiment, a liquid nozzle is controlled by a control valve such as to maintain the constant moisture content. In another embodiment, a high intensity mixture is provided for mixing dry powder in varying amount with high moisture material to produce pellets having substantially constant surface moisture when discharged from the pelletizing disc.

Abstract: A head supported portable radio assembly that eliminates the inconvenience of having earphone cables extend from the ears to a distantly housed radio or cassette player. It comprises an expandable rubber tubular headband that is worn around the head in combination with a self-contained miniature personal AM/FM stereo radio or mini cassette player. The headband and radio or cassette player can be worn as an attachment to the temples of all types of glasses and sunglasses or it can be worn as a headband that wraps completely around the head therefore does not require attachment to glasses. The tubular headband is designed to keep the wearer's glasses and the attached radio or cassette player from slipping from the head during physical activity. The tubular headband also serves as a conduit for transporting the earphone cables and earphones from the radio or cassette player to the wearer's ears.

Abstract: A golf ball position marker detachably secured to a supporting strip attached to a golfer's belt or golf bag. A pouch having a pair of tabs may be supported on the supporting strip, either by looping the tabs thereon or by attaching the tabs directly onto the supporting strip. Interpenetrating fibers are provided on coacting faces of the marker, supporting strip, and tabs, so that the marker and tabs may be detachably fastened to the supporting strip.

Abstract: A manually operable unit having a single handle for driving, steering and tilting a boat propeller. The crank handle, when turned, drives the propeller through bevel gearing. A vertical sleeve surrounding a vertical drive shaft has an offset U-shaped portion terminating in a sleeve serving as a bearing for the crank handle. Pushing the crank handle against the bearing rotates the vertical sleeve which mounts the propeller, therefore steering the propeller. Pulling of the handle will tilt the vertical sleeve with respect to a mounting C-clamp to pivotally raise the propeller.
