Abstract: Cross-linked polymer microspheres are carefully separated into fractions of equal size and density by first using sieves and then using hydraulic separation in a cone. Each fraction is separately plated with copper. The copper plated microspheres are again separated into fractions of equal size and density. Each fraction is then given an additional metal plating. The thus plated microspheres have uniformly thick plating and have a maximized surface area for the amount of metal plated making them particularly useful as catalysts or in electrical products or processes. Microspheres having a plating of palladium exhibit a marked improvement in the adsorption of hydrogen both quantitatively and in rapidity.

Abstract: A pavement cleaning vehicle having brushes for dislodging and sweeping rearwardly debris, is provided with elongated air nozzles which direct the debris towards suction heads. The air nozzles extend angularly outward and forward from a location along the center line of the vehicle and have curved end portions which curl inward from the vehicle sides in circular arcs. Suction heads are disposed at the center of the arcs and a suction head is also disposed adjacent to the centrally located nozzle ends.

Abstract: An elongated metal channel having a U-shaped cross-section has a cover and end caps secured thereto forming a housing. Along one wall of the housing are drilled longitudinally spaced holes. In some of the holes (which may have different orientations) are fixed metal collars having secured therein one end of a bundle of optical fibers. The fiber ends are secured by an adhesive which has been cured, after which the ends are polished. The fiber bundles are led through the housing to an opening (which may be in the cover) where a flexible sleeve has one end mounted. The fibers are threaded through the flexible sleeve and secured in a tip at the other end of the sleeve. The fibers in the tip are secured therein by an epoxy and polished. In some cases the metal collars with the fiber bundle are positioned at the end of a gooseneck with a lens mounted adjacent to the tip. The method by which the fibers are mounted in the collars is described.

Abstract: A folding building structure has a fixed roof formed by joining a plurality of identical triangles which have two equal side edges, a base edge and an apex opposite the base edge. All these apexes meet at a common point. To each roof base edge is hingedly joined the coextensive base edge of a wall triangle having two equal side edges. Each side edge of a wall triangle has hingedly joined thereto the hypotenuse edge of a right triangular wall panel. Each right triangular wall panel has a side edge equal to the height of the wall triangles having two equal side edges, and adjacent side edges of the right triangular wall panels are hingedly joined.

Abstract: A system for removing volatilizable organic contaminants from solid materials has a primary volatilizer and a secondary volatilizer positioned in series. A charging system continuously loads solid materials which have been blended to contain a predetermined concentration of contaminants into the primary volatilizer. A portion of the contaminants are volatilized in the primary volatilizer. The solid materials and the volatilized contaminants are transfered to the secondary volatilizer where the volatilized contaminants are burned to provide heat for help in volatilizing the remainder of the contaminants. The solid material which is now decontaminated is quenched. The gases are treated to convert the remaining volatilized contaminants to harmless gases and water vapor. Particulate material is removed from the gases. Nitrogen oxides and sulpher are also converted to harmless forms.

Abstract: A dual action piston pump has a centrally disposed pump cylinder having a pump piston therein. A transition section is secured to each end of said pump cylinder through which the media being pumped passes while being pumped from and to a four way valve. A piston rod is connected to each side of said pump piston. Each piston rod passes through the side wall of the transition section and extends into a drive cylinder where it is connected to a drive piston. The drive pistons are driven by a motive fluid which may be hydraulic fluid. Each drive cylinder has a motive fluid connection adjacent to its distal and proximal ends so that both drive pistons can be driven in both directions. As the pump piston moves in one direction media is being pumped out on one side while media is being drawn in on the opposite side. The four way valve connects one side of the cylinder to a suction intake and the other side of the cylinder to the discharge. The valve reverses these connections when the stroke of the pistons reverse.

Abstract: A spare tire support for a vehicle having a horizontally hinged rear closure has an L-shaped swing bracket secured in the space between the right rear light assembly and the upwardly extending internal frame by bolts through the internal frame. Nuts for these bolts are fastened by removing the rear light assembly to expose the access holes therein. The short leg of the swing bracket is below and spaced from the horizontally extending frame member (typically a box frame). A horizontal swing bar has one end mounted in this space on a hinge bolt which extends from the top of the horizontal frame member and through the short leg of the swing bracket. The horizontal swing bar is moveable between a stowed position below the horizontal frame member and an unstowed position clear of the vehicle rear closure. Joined to the horizontal swing bar (as by welding) is a short bar which extends outwardly sufficiently to clear the horizontal frame and rear bumper, if any.

Abstract: An external incontinency device having first and second rigid, arcuate members hinged together at one end has a releaseable securing device at the other end. The inside of the first member is padded. A compression bar having a padded upper surface is hingedly mounted at one end to the second member. The compression bar is moveable between a position in which it will compress the uretha and a position in which the uretha is not compressed. An L-shaped lever is pivotally mounted in a slot in the second member at the juncture of its two legs. One leg extends outside the second member and serves as an operating handle. The other leg engages the compression bar to cause it to compress. Moving the handle will disengage the other leg to permit urination.In an alternate embodiment the second arcuate member serves to compress the uretha. In this embodiment the device must be loosened to urinate.

Abstract: A hollow, cellulose acetate fiber having a wall permeable to water is formed into a coil of constant dimensions. The coil is placed at the root level of the plants to be irrigated. Where the plants are spaced at intervals (as opposed to being immediately adjacent) a number of coil turns are positioned at the plant location and the coil stretched out between plant locations. In this manner, irrigation is concentrated at the plant and minimized in the intervening distance. Consequently, even though the coil is of constant dimensions and porosity, the quantity of water dispensed can be varied as desired. Similarly the spacing between parallel coils can be varied. This spacing variation is desirable where the pressure of the water varies because of height changes, on a slope for example. The subterraneon watering by coil has an additional beneficial effect because the roots of the plants tend to concentrate within the turns of the coil so as to become anchored thereto.

Abstract: Exercise equipment having a reciprocating extendible and retractible tension transmitting device is equipped with a control which restricts the extension to a constant velocity and impose a compulsory constant velocity retraction. The control may be hydraulic or electrical and may be a linear actuator. Transducers, and/or a load cell connected to the apparatus produce signals representing the performance of the user. These signals are processed by a control computer which produces control signals. The computer may also produce signals representing the user's previous performance for display and storage. The display may be an audiovisual display presenting animated graphics representing the user's present exercise performance as compared with the user's previous performance. The display also provides incentive, reinforcement, and motivation based upon the utilization of the comparative performance data. A sound generation system generates encouraging spoken remarks and provides background music.

Abstract: A vertically extending distillation cylinder has a closed top and an open bottom having an electric heating element disposed therein to form a closure. Adjacent to the top of the distillation cylinder is connected a condensing tube. The condensing tube extends down through a condenser having a cooling water inlet at the bottom and a water discharge at the top. A throttle valve regulates the flow of cooling water. From the water discharge, a trough carries the water to impinge on the distillation cylinder causing pollutants to vaporize. The water collects below in a basin surrounding the distillation cylinder. A feed tube carries water from the basin to the bottom of the distillation cylinder. A discharge tube also connected to the bottom of the distillation cylinder carries water up to where it makes a U-turn. This regulates water height in the distillation cylinder. The discharge tube and an over flow tube from the basin discharge into a funnel from which water is conveyed to a sewer.

Abstract: An asphalt recycling conveyor system has a substantially horizontal collecting trough for receiving returned, unused hot mix asphalt. Deflecting plates are provided at the back and ends of this trough, and spaced guard rails extend across it. Asphalt is moved in the trough by an auger having standard pitch to a hopper at one end of the trough. Asphalt lump breaking rods extend from the auger shaft above the hopper to prevent these lumps from bridging the hopper opening. An elevating trough may receive the asphalt from the collection trough hopper and carry it to a higher elevation. The elevating trough has an auger having one-half standard pitch and is turned at a faster speed than the collection trough auger. Heat trace lines are provided on the bottom of the troughs to prevent asphalt buildup.
