Abstract: A sludge processor is provided which enables rapid disassembly and reassembly for changing between a sludge thickener configuration and a press configuration, and for enabling rapid disassembly for cleaning in the press configuration. The processor includes a frame with opposite sides and roller-holding bearing devices at the opposite sides for holding rollers about which a belt extends past a sludge dewatering region. The bearing devices can be arranged in a first configuration (FIG. 2) wherein the belt (12A) extends in an even path, and a second configuration (FIG. 1) wherein the belt extends in a tightly convoluted path so it and material thereon is squeezed between adjacent rollers. The bearing devices (50, FIG. 4) are releasably mounted to the frame sides to enable rapid conversion, and to enable rapid removal of the rollers for cleaning the processor when used in the second configuration.

Abstract: A light computer is provided for illuminated and animated displays. Light planes are illuminated and images carried thereon are lit when light is applied to any edge. A moving light and opaque coatings on the edges of the light plane are used to vary the sequence and time the frequency and duration of the lighting of the plane. When an opaque coating is positioned between the light and the plane, the plane does not light. Only when the opaque coating is not present and the light is present is the plane lit. In a preferred embodiment, the light source is mounted at the end of a stack of circular light planes and light from the light source is admitted to the edges of the light planes by means of a rotating mask having a window leading to a prism for reflecting the light onto the edges.

Abstract: A staged mold for stabilizing hazardous wastes for final disposal by molding an agglomerate of the hazardous wastes and encapsulating the agglomerate. Three stages are employed in the process. In the first stage, a first mold body is positioned on a first mold base, a mixture of the hazardous wastes and a thermosetting plastic is loaded into the mold, the mixture is mechanically compressed, heat is applied to cure the mixture to form a rigid agglomerate, and the first mold body is removed leaving the agglomerate sitting on the first mold base. In the second stage, a clamshell second mold body is positioned around the agglomerate and the first mold base, a powdered thermoplastic resin is poured on top of the agglomerate and in the gap between the sides of the agglomerate and the second mold body, the thermoplastic is compressed, heat is applied to melt the thermoplastic, and the plastic is cooled jacketing the agglomerate on the top and sides.

Abstract: A toy skateboard is provided with steerable truck assemblies having a minimum of parts. Two longitudinally spaced pivots on the underside of the platform hold the trucks on the platform. A leaf spring with three prongs is placed between each truck and the platform. One or more of the prongs are bent away from the plane of the body of the spring with the two outer prongs always located in the same direction. The diameter of the pivots is less than the diameter of the holes through the trucks allowing the trucks to be tilted in any direction about the pivots. Limit walls molded on the undersurface of the platform limit the rotation of the trucks about the pivots. When the platform is tilted, the springs push the trucks out of the straight forward position into the direction of the tilt thereby mimicking the action of a full sized skateboard.

Abstract: A produce rack for the display and storage of produce having a display surface and an opening allowing the produce to be viewed. Refrigerated air is provided to the produce through the display surface. Water is periodically sprayed onto the produce by an automatic watering system. A flexible cover selectively closes the opening to optimize the condition of the air inside the display area. The cover includes a plurality of transparent curtains that roll up on rollers for storage and roll down for use. Strip connectors close the gaps between adjacent curtains. Hook and loop fasteners on the edges of the curtains and connectors allow the connectors to be secured to the curtains across the gaps simply by placing the connectors across the gaps.

Abstract: A disposable cap and cape is provided for use during the chemical processing of hair both during the waiting period and the rinsing phase. It is preferrably fabricated from a single rectangular sheet of thin flexible plastic. The cap portion is formed at one end by folding the sheet over onto itself and welding the sides to each. A U-shaped neck cutout is made at the other end creating ties from the remaining material on either side. When the device is used as a cap, the cap portion is fitted over the head and the chemical is retained inside by the proximity of the sheet material. When the device is used as a cape, one tie is positioned on each side of the head, the device is pulled up to the back of the neck, the ties are tied together at the forehead, and the cap portion is allowed to drape down the back. Rinse water and chemicals then flow over the outside of the former cap into a sink.

Abstract: A game bag for a scuba diver is provided having a flexible tubular envelope with an open end or mouth and a closed end. The mouth is coupled to the diver's weight belt at his hip while the remainder of the envelope wraps around behind his seat and adjacent leg between his legs where it is again couple to his weight belt at his front abdomen. The legs serve as a doorway into the receiver portion of the bag. Game is pushed into the mouth of the bag with one hand, between the legs which are opened to allow passage, and into the receiver portion where it is retained by the closure of the legs on the bag. A separate latch on the mouth of the bag may be used to close the mouth although it is not required to retain the game in the receiver portion.

Abstract: A vehicle tray is provided for mounting on the inside of a door by hooking the outer end of the tray onto the door between the window and the inner door panel and rotating an arm down from the bottom of the tray to a fastener means previously attached to the inner panel. The fastener means is a hook fastener material cooperating with a loop fastener material such as sold under the trademark Velcro.RTM. with one portion on the door and one portion on the arm. A rotating face on the arm aligns with the plane of the inner door panel allowing optimal contact between the two fastener materials.
