Abstract: A method for detoxification of spent catalyst from a fluorination process includes the step of hydrolyzing such spent catalyst in the presence of aqueous calcium chloride to produce insoluble compounds which are separable from the aqueous medium. The spent catalyst is one which includes at least one antimony halide, such as SbCl.sub.5, SbF.sub.5, SbCl.sub.3 and/or SbF.sub.3, usually with some halogenated hydrocarbons, such as partially chlorinated methane, partially chlorinated ethane and/or chlorofluorocarbons of 1 to 5 carbon atoms, often in the presence of arsenic compounds, such as AsCl.sub.3, hydrofluoric acid, and antimony chlorofluoride, such as SbCl.sub.4 F. The spent catalyst may be directly treated with the aqueous calcium chloride solution, very preferably with such solution containing small amounts of a transition metal ion, such as Fe.sup.++ or Fe.sup.+++, or aluminum ion, e.g., Al.sup.

Abstract: A golf putter head of substantially squared W-shape, when viewed from the top thereof, preferably with weights in the outer leg portions of such W, facilitates straighter and more accurate putting. When the walls of the middle leg of the W of the club head (or the middle trailing portion of such head) slope endwardly and downwardly a golfer may correctly position his head above the putter and the ball by viewing the slope areas and moving his head position until such areas appear equal (or in desired ratio). Preferably, the putter head includes internal weights in upper portions so located that the vertical center of gravity of the putter head, in putting position, is at or above the midpoint of a ball to be putted.

Abstract: A battle type game, which is readily constructed, includes simple electric circuitry for actuating signals to indicate hits made. The signals are actuated by completion of an electric circuit due to contact of an electrically conductive piercing portion of a piercing probe member, which may be a bulletin board type tack, with an electrically conductive head portion of a contact member, which may be a substantially flat headed metal thumbtack, representing a target or a part thereof. The invention is preferably made from a kit of components, readily assemblable by a youthful prospective player of the game. Also within the invention is the provision of cover sheets, having grid indicia thereon, for use to cover a corresponding marked sheet on a circuit board, for playing of the game, on which the target members are placed.

Abstract: An oxygen supply apparatus, particularly for use by a coal miner, has a plurality of housings mounted on a belt, which is worn by the miner, with each housing having a cartridge of oxygen generating material therein and removable from the bottom thereof for replacement. Each housing has a cover with a resiliently biased shaft supported thereby for relative movement to activate the oxygen generating material in the cartridge. The shaft functions as a timer activator so that the timer is set when the shaft is activated. The timer produces an alarm signal just prior to the expiration of time for depletion of oxygen from the cartridge within the housing. Each of the covers has a chamber receiving the oxygen from the cartridge and supplying it through tubing to oxygen receiving means worn by the miner such as a mask, for example.

Abstract: Radioactive waste material, such as that resulting from radioactive weapons plant operation or from nuclear fuel reprocessing, in suitable form, such as radionuclide-containing oxide and/or oxyhydroxide and/or hydroxide particles, is held by a metal or metal "alloy" to an electrically conductive cathodic material upon which the metal or alloy is electrodeposited. In this way the radionuclide species including strontium and/or cesium, which are biologically extremely hazardous, are incorporated into a metal matrix held to a base and may be disposed of, as by underground storage, in such form, which is considered to be more resistant to dissolution by ground water and to damage by mechanical stresses arising from tectonic activity than are glasses or ceramics incorporating radionuclides.

Abstract: Walls and partitions are constructed by securing of wallboard panels to a substructure, such as common wood or metal framing members, by a series of concealed clips of described construction, affixed to the framing members by nail or screw type fasteners. When the wall or partition is erected the fasteners are hidden from view so that joint treatment of the wallboard panels may be reduced or eliminated, depending on the type of wall structure constructed. The side or edge gripping clips are impaled along each side of abutting panels. When erected, a first series of clip fasteners are impaled on a side of a first wallboard and fastened to a framing member and a second series of such fasteners are impaled on an abutting or nearly abutting side of a second, wallboard panel, offset from the first series of clips so as to fit behind and be held by the first panel in a "tongue and groove" type cooperation.

Abstract: An elastic detergent bar of improved elevated temperature stability, so that it better maintains its shape on storage at temperatures somewhat higher than normal, includes an amphoteric synthetic organic detergent in mixture with an anionic synthetic organic detergent, gelatin, water and insoluble gas in very small bubble form distributed throughout the bar. The bars are substantially form-retaining during storage and although they wear away during use, substantially retain their initial forms and elasticities for major proportions of their useful lives. Compared to similar bars in which the insoluble gas, such as air, is not present, the invented bars are stable at higher storage temperatures, e.g., 5.degree. to 10.degree. C. higher, making them commercially much more acceptable.

Abstract: A dental articulator of simplified structure, capable of relatively forward and sideward movements to simulate human jaw movements, includes component parts representing lower jaw and maxillary structures held together at simulated condylar joints, wherein spring means press simulated condyles against matching condylar joint walls to hold them in such position when desired and disengaging means are provided which, when actuated, move the spring means away from the associated condyle part, facilitating relative movement of the simulated jaw parts at such joint. When both ends of the spring are moved away from the condyles the jaw portions of the articulator may be separated so that examination of the wear surfaces of dentures held therein may be effected easily.
