Abstract: A method of making irregular shaped playing discs to achieve proper balance for playing involves the use of a grid (7) divided into quadrants (1, 2, 3, 4) having squares of a predetermined size. A template (8) is placed on the grid (7) into which a desired artwork (9) is fitted. The artwork may include face of a recording star, holiday character or other desired item. The artwork (9) must be placed within the template (8) so that an equal number of squares is taken from each quadrant (1, 2, 3, 4) of the grid (7) within the template (8). Once the shape of the artwork is determined, the recording medium, whether it be audio, visual or a combination of both, is applied. The visual appearance of the artwork (9) may then be silk screened or otherwise applied to the disc. Once the above method is accomplished, the disc can be used as a master for making a mold to premold other discs or each disc may be cut around the perimeter of the artwork to result in discs in the shape of the artwork.

Abstract: Sandwich fiberglass laminate components and a process for fabricating same for boats and the like. The process employs a unique vacuum manifold (12) incorporated into the mold to an inner layer (3) of the component. Also, recesses in the mold are covered with pre-made inserts (22) molded into the layer to form hollow boxes (4, 5) for instruments, consoles and beams. The hollow boxes may be reinforced with metal inserts (20) for attaching support beams. Atmospheric feed holes (21) are drilled into the hollow boxes to prevent collapse of the boxes during the molding process and to yield a better mold. After the molding process the periphery of the component may be trimmed to form an integral edge (7) of the component. This process results in a sandwich fiberglass boat hull or other component having finished inner (3) and outer (2) layers with hollow boxes for instruments, consoles and support beams which are integral with at least one layer of the component and edges without layer separation.

Abstract: A recreational vehicle (RV) waste drainer having a drainer sheath (1) with an angled drain nipple (3) at a receptacle end in fluid communication with an expandable tube (5) in the drainer sheath. A drain end of the expandable tube is attached to the drain nipple. A holding-tank connector (6) on a holding-tank end of the expandable tube connects the expandable tube to an RV holding tank (21, 22) for draining it and connects the expandable tube to a sheath lid (4) for sealing the drainer sheath and the expandable tube against escape of odorous gases and liquid at a tube end of the drainer sheath when not in use. The drain nipple has a beveled nipple-attachment wall (9) that is resilient and sized to fit inside of receptacle pipes (10) of RV sewage receptacles (11). A nipple lid (2) has a nipple sleeve that fits onto the beveled outside periphery of the drain nipple like an input pipe to seal the drainer sheath against escape of odorous gases and liquid at the drain nipple when not in use.

Abstract: A grout- and hard-surface cleaner has a water-blast nozzle (5) positioned on a cleaning enclosure (1) to direct a high-pressure and low-volume jet stream of water (36, 37) and optional cleaning material at an attitude onto a surface (4) being cleaned. Resilient and preferably rubberlike surfaces (14) are provided on bottom portions (2) of walls of the cleaning enclosure to facilitate sliding-seal contact with the cleaning enclosure and to provide sliding ease of movement with water and optional cleaning fluid to provide lubricity between the surface being cleaned and the bottom edges of the cleaning enclosure. A wet-vacuum suction tube (12) positioned on a top suction portion (3) of the cleaning enclosure provides low-pressure and high-volume suction pressure that is that provides a level of suction for sliding-seal contact of the cleaning enclosure against the surface being cleaned.

Abstract: A motion-picture-projection system has a top intermittent sprocket (1) and a bottom intermittent sprocket (6) that are rotated intermittently in unison by mechanical and/or electrical means (8, 9, 19, 20, 21, 22, 23, 24) for conveyance of film (3) through a film gate (4) without formation of loops of film between the top intermittent sprocket and the film-gate outlet sprocket. To compensate for differences of length of unreeled film due to its cyclic advance and film-frame stoppage, compensatory loops (16, 17) are formed prior to instead of after a top intermittent sprocket and after instead of before a film-gate outlet sprocket. A film-contact surface (25, 26) of a film gate is arcuate and bordered with non-abrasive and suitably pliable material to minimize film wear. Air can be pumped onto the film for cooling and for distortion contamination resulting from heat absorption formation that is related to film "breathing".

Abstract: A method and system for direct routing of telephone calls made by a caller originating from within specific calling areas to one of a plurality of locations of a second party according to certain criteria established by the second party. This routing is accomplished based on the assignment of latitude and longitude coordinates to a potential caller's location. Once these coordinates are assigned to each of the potential callers, the second party's criteria is applied to assign the potential caller to a second party. Such criteria could be existence within a previously-defined geographic area, a custom defined geographic area, or through calculations such as the shortest distance between coordinate points. Once all such assignments have been made, a database is assembled to be used by a long distance carrier for direct routing of telephone calls from callers to an assigned second party.
