Abstract: Precious metals are resolved and recovered from complex ores by a repetitious process of (1) heating in an electric arc furnace, a source containing complex ore values with fluxes and a base metal, to which a precious metal inquart has preferably been added, thereby smelting the precious metal values into the base metal; (2) transferring the base metal in an acid-proof bag to an electrolytic cell where the base metal becomes the anode and subjecting the cell to a direct positive current causing the base metal and unresolved "complex" values to be dissolved from the anode and plate out on a cathode leaving the precious metal inquart and resolved precious metals in the acid-proof bag in the form of an anode mud; (3) charging the cathode and any undissolved anode back to the smelting operation and repeating the smelting and electrolysis operations as many times as necessary to resolve the complex values in the source and collecting them in the anode mud.

Abstract: A holder assembly for remote control units used with television sets, recorders, stereos, home entertainment centers and the like and comprising an adjustably sized control unit holder adapted to be interconnected with other similarly constructed holders.
Abstract: A method for producing articles of polyurethane or the like wherein a mold of the article shape is positioned to centrifugally receive a polyurethane composition comprising polyisocyanates, polyol, water and fluorocarbons such that the polyurethane molecules striking the wall of the mold are broken to provide a resulting smooth non-porous outer skin for the article and wherein additional polyurethane materials provide a foamed interior for the article. The water serves as a reactive polyol and reacts with the polyisocyanate to create carbon dioxide gas which yields increased expansion pressure which causes the foaming polymer to produce a uniform skin around a cellular inner core.
Abstract: A jig for aligning cutter blades including positioning bars each with a holding magnet insert at one end thereof to engage and hold blades of a cutter head of a woodworking machine as the blades are locked in place and stabilizing magnets spaced along the other end of each positioning bar; and means to adjust the relative spacing between positioning bars while maintaining such bars in a parallel relationship.
Abstract: This invention relates to a container carrier formed from a flat sheet of durable, flexible material. In a preferred embodiment, the container carrier includes four sets of concentric drinking cup carrying holes, each set of holes comprising a smaller hole dimensioned to fit around the circumference of the lower portion of a conventional drinking cup, and the larger hole dimensioned to fit around the circumference of the upper portion of said cup. The sets of holes are positioned symmetrically about transverse and longitudinal axes of the device. Outboard of the two sets of holes that are symmetric about the longitudinal axis are formed two handle members that join together to form a handle for carrying the device and drinking cups carried by the device.
Abstract: The invention relates to a pickup truck having a cab and a bed with a disappearing camper built into the bed, i.e., one which has a lower concealed position and an upper camper position with each side wall of the camper being made in three sections from panel material such as plywood, fiber glass, plastic, etc., having at least a part thereof made of transparent material to serve as windows for the camper. Each side wall has four support rods, one secured to the front edge of the front section, a second secured to the back edge of the front section and the front edge of the middle section, a third secured to the back edge of the middle section and the front edge of the back section, and a fourth secured to the back edge of the back section. The middle section is of variable height to accomodate the rear wheel humps in the bed. Three embodiments of means to raise and lower the camper are disclosed, viz.
Abstract: A metal lock system is provided for securing a crack or break in a metal casting from further cracking, breaking, or leakage. The metal lock system includes a metal lock having parallel, flat top and bottom surfaces and a plurality of alternating large and small lobes, and a plurality of tapered lacing plugs. The metal lock is imbedded into an irregular recess of precision drilled bores disposed adjacently in intersecting alignment. This binds the crack or break from further separation while the crack or break is sealed by imbedding tapered lacing plugs into lacing bores which are drilled along the crack. The preferred lacing plug has a tapered shaft, straight threads, a shoulder, and a break-off groove. the preferred tapered lacing plug threads into lacing bores with straight threads and the shoulder seats the lacing plug by crushing the first few threads of the lacing bore. The head of the lacing plug breaks off at the break-off groove at a predetermined torque.
Abstract: A multi-faceted toy having eight heptahedrons that are anchored to a central sphere; four of the heptahedrons are each attached directly to the central sphere with internal axles that have one end anchored securely in the central sphere; the other four heptahedrons are mounted on axles which are anchored to a convex base plate that is movable and that can be rotated in an orbit around the central sphere by means of an internal tongue and groove system which provides raceways for movement as well as interlocking of the individual components to the central sphere.
Abstract: A safety spray wand for use in car wash units, and the like, having selected valve units, each with a single moving valve part to provide controlled flow through a valve housing; a break-away, variable length barrel assembly connected to the valve housing and with the housing structure made to withstand even severe vandalism and to accommodate swivel coupling of a supply line to the wand.
Abstract: A multiple firing elastic shooter toy including a handle, a rod which may take the form of a barrel and having a notched end to receive lengths of elastic members and a receiver section interconnecting the handle and the rod. The receiver section is of generally U-shaped cross-section and has a web at one side of the shooter and top and bottom legs. Spaced apart slots are formed in the web and partially into the legs of the receiver to accept other lengths of the elastic members. A snubber post projects from the shooter toy at the side opposite the web and forwardly of the slots in the direction of the rod and serves as a safety against inadvertant release of stretched elastic members.
