Abstract: A folder for holding, displaying and securing a compact disc made from a single sheet of card stock. The rectangular sheet is folded into three equal rectangular sections and a semicircular section is cut out of one of the two end sections of the sheet leaving a semicircular tab at the center of the cut out section. The diameter of the semicircular cut out section is sized slightly larger than the diameter of the compact disc. Glue is applied to the end section of the sheet containing the cut out and that section is folded over and glued to the center section of the sheet, thus forming a pocket sized to receive one half of a compact disc. The semicircular tab is sized to cover that portion of the compact disc surrounding the hole in its center so that a plastic rivet passing through the semicircular tab, the hole in the disc and the center section of the sheet of card stock will secure the disc within the folder.

Abstract: A simplified attachment for a mailbox which alerts the mailbox addressee that mail has been delivered. The attachment includes a signal flag mounted on a spring activated spool rotatably secured within a housing affixed to the side of the mailbox. When the mailbox door is closed, the upper end of the signal flag is held under tension in a horizontal position by a keeper mounted on the door of the mailbox. When the mailbox door is opened, the signal flag is released from its horizontal position and, powered by the spring, rises to a vertical position above the mailbox to alert the addressee that the mail has arrived.

Abstract: A readily assembled container for holding a plurality of filled trash bags awaiting collection. The container consists of six rectangular panels each having a polyvinyl chloride (PVC) pipe frame and a section of galvanized wire hardware cloth attached to the inside of the frame. Five of the six panels are designed and sized to be bolted together to form the sides and bottom of a knock-down trash container. The sixth panel is sized to form a cover connected to the container by a pair of hinges. The container is supported above the ground by four legs of variable length also made of PVC pipe which fit into sockets at the four bottom corners of the assembled container.

Abstract: A composite horseshoe made of a resilient urethane material and containing therein four separate, spaced apart metal inserts. The first metal insert forms a core in the shape of a horseshoe and lies entirely within the resilient horseshoe. The second and third metal inserts are relatively short elongated plates which lie above the two ends of the first metal insert, with the upper face of each plate lying flush with the surface of the resilient horseshoe. The fourth metal insert is a curved elongated plate called the toe grab which lies along the front of the resilient horseshoe and projects outwardly from the resilient horseshoe.

Abstract: An equalizing tilting pad assembly for thrust bearings and the like which includes a retaining ring housing an arrangement of upper and lower equalizing links and supporting a number of similar tilting pads each having a spherically curved contact surface on its lower face. The upper and lower equalizing links lie within the retaining ring in an endless overlapping arrangement with each upper link touching at contact points two adjacent lower links. Each upper link is pivotally mounted on a spherical ball supported by the retaining ring and each lower link is pivotally mounted on the retaining ring by cylindrical members lying perpendicular to the axis of the retaining ring, and the contact points between adjacent upper and lower links lie in a common plane when the equalizing links are in a position of zero pivoting angle.

Abstract: An automobile steering assembly to be mounted on a wheelchair for therapeutic purposes. The steering wheel is rotatably mounted on a plate attached to the horizontal center section of a tubular frame which fits onto the frame of the wheelchair. The steering wheel is positioned so that it is presented to the person seated in the wheelchair in the same position that the steering wheel of an automobile is presented to the seated driver of the automobile so that the person in the wheelchair can grasp the steering wheel as though he or she were the driver of an automobile. The steering wheel is mounted so it can be rotated or turned about its central axis similarly to the turning of an automobile steering wheel. However, unlike an automobile steering wheel, the therapy steering wheel includes manually adjustable means for varying the amount of force required to turn the therapy steering wheel.

Abstract: A cylindrical internally contoured sleeve-shaped attachment for a screwdriver designed to prevent the screwdriver from slipping out of a slotted head screw and thereby inflicting injury to the fingers or work piece. A cushioned end prevents any marring of the work piece. This attachment is preferably molded of clear plastic material and has no direct mechanical connection to the screwdriver.

Abstract: A self-manipulatable assembly for moving a person's leg encased from the thigh to the foot in a surgical cast. The assembly includes an elongated first strap made of a non-elastic flexible material extending from the ankle portion to the thigh portion of the cast, a second strap made of flexible hook and loop self-locking material encircling the ankle portion of the cast and securing one end of the first strap, and a third strap made of flexible hook and loop self-locking material encircling the thigh portion of the cast and securing the other end of the first strap. The length of the first strap being greater than the distance between the second and third straps.

Abstract: A butt hinge assembly for a door hinged to a casement which keeps the opened door from moving on its hinges due to air currents or other forces acting on the surfaces of the open door. The assembly consists of a conventional butt hinge having two cooperating hinge plates joined together by a hinge pin fitted into the aligned cylidrical knuckles formed on the adjoining ends of the two hinge plates and a flat tempered spring steel plate sized to fit against the hinge plate mounted on the casement and positioned between the casement and the hinge plate. The spring steel plate has a plurality of flat fingers or extensions each sized to press against one of the cylindrical knuckles of the hinge plate which is mounted on the door.

Abstract: A disposable one-piece pet feeding dish having a thin walled central bowl surrounded by a thin walled outwardly sloping skirt, the bottom of the central bowl being substantially flat and lying in the same plane as the lower edge of the dish's skirt, a patch covered with adhesive affixed to the flat outside surface of the bottom of the bowl, and a sheet of release paper covering the adhesive surface of the patch.

Abstract: A system utilizing at least three separate water pumps for supplying water under pressure to a plurality of nozzles in a fountain display which provides a wide variety of spray heights of the various nozzles. The nozzles are spaced along a main water supply pipe and the pumps are connected to the main water supply pipe at spaced apart entry points along the pipe with a one-way check valve between each pump and the mainwater supply pipe. An independently controllable and incrementally variable gate valve is also located between each pump and the main water supply pipe. Additional versatility and variety of the sprays projected from the nozzles can be obtained by use of additional check valves located along the main water supply pipe between each of the entry points of water supplied by the pumps which pass water under pressure only in one or the other direction.

Abstract: A housing contains a plurality of tetrahedron shaped dice. The faces of the dice bear one or more indicia. The housing includes a tumbling compartment in which all of the dice are shaken and a smaller plurality of pyramidal shaped cavities in which certain of the dice are then disposed for viewing. At least a portion of one face of each die is visible through the wall of the housing in one embodiment, while at least a portion of two faces of each die is visible in another embodiment.

Abstract: A method of repairing a leaking coupling between an air conditioning cooling coil and its associated expansion valve using a split clamp-on coupling nut. The nut consists of two mirror-image halves, the two halves being joined together by a pair of screws. The joined together halves provide a passageway sized and partially threaded to accommodate the flanged end of the cooling coil pipe and the threaded end of the expansion valve pipe when these two pipes are aligned along a common axis and the end of the expansion valve pipe abuts against the flange of the cooling coil pipe.
