Abstract: The invention provides a thermal break configuration in a flush glazed, two-piece mullion which permits a reduced face dimension without reducing the depth of the glazing channels of the mullion. The invention is directed to a thermal break segmented filler assembly for the shallow glazing pocket in narrow flush glazed two-piece framing for curtainwalls, storefronts, and the like. The two-piece mullions have a major portion and a filler portion, both of which are extruded profiles. The filler assembly incorporates a thin thermal break which makes it possible to reduce the mullion face dimension and still provide a glazing pocket depth equal to that of conventional flush glazed thermal framing. The thin thermal break of the filler assembly includes a plastic channel extrusion having rigid upturned legs with relatively soft barbs which engage channels in aluminum extrusion filler halves. The thermal break filler element is snap fit onto and between the filler halves to form a three-piece filler assembly.

Abstract: A method is provided for removal of surface oxide from a continuously cast copper bar preparatory to inline hot rolling, wherein solidified bar continuously advancing from a continuous caster is directed to a continuous hot rolling mill, comprising: passing said advancing bar, being at hot rolling temperature, through a spray zone of selected quench capacity and impulse, such that for each segment of said bar passing through said spray zone, said oxide is quenched to a black heat but is not ablated and said underlying bar is subjected to a shallow quench; said spray zone being situated in close proximity to but selectively spaced upcourse from the first rolls of said hot rolling mill such that there is insufficient time for substantial reheating of said quenched oxide during the approach to said first rolls; whereupon as quenched segments of the advancing bar progressively approach said first rolls and said underlying bar begins to deform just prior to roll contact, said oxide spalls off the bar surfaces subs

Abstract: Disclosed is an integrated system for continuously melting and refining secondary and blister copper to produce and continuously cast anode grade copper comprising: continuous melting of secondary and blister copper in an optional fuel vertical shaft furnace; continuously or semicontinuously skimming initial slag from the surface of the melted copper in a slag vessel as it drains from the shaft furnace; collecting a reservoir of molten copper in a holding furnace capable of controlling its temperature and subsequent flow; adding fluxes to the molten copper; directing the molten copper into an oxidation vessel where the molten copper and impurities are oxidized; transferring the oxidized and fluxed molten copper to a second slag vessel where slag is skimmed from its surface; flowing the oxygen rich molten copper into a reduction vessel where oxygen content is reduced; collecting a supply of refined molten copper in a final holding vessel; continuously passing the refined molten copper through a filtering ladle

Abstract: A process is provided for purification of nickel sulfate via ammoniacal leaching and pH regulated solvent-extraction, while providing for regeneration of the extractant and the leach solution. The process is especially suited for hydrometallurgical extraction of high purity nickel sulfate from residue resulting in the regeneration of spent electrolyte in the electrorefining of secondary copper. According to the process, the starting material is leached in an ammonia solution of selected pH to solubilize the nickel as polyammine sulfate, followed by extracting the solubilized nickel by pH regulated solvent-extraction. The extractant is then stripped and regenerated with sulfuric acid by first scrubbing in a first pH range to remove ions that are more electropositive than nickel, then stripping with sulfuric acid in a second pH range to remove nickel ions, and then regenerating the extractant by stripping in a third pH range to remove ions that are less electropositive than nickel.

Abstract: A hydrometallurgical process is provided for the separative treatment of electrometallurgical anode slime containing precious metals and substantial amounts of tin dioxide and lead sulfate. The process is especially suited for treatment of anode slimes from the electrorefining of secondary copper to recover about 85% of the metal value contained therein, especially tin and precious metals. First, lead is separated by leaching the slime with diethylene triamine followed by carbonation to precipitate lead carbonate with subsequent regeneration of the leach solution. Second, tin is separated by leaching the undissolved residue from the amine leach with a solution of hydrochloric acid and chlorine to dissolve substantially all substances except tin dioxide.

Abstract: A flywheel is provided for storing rotational energy at high energy densities and which possesses a primary failure mode of delamination. The flywheel is constructed from glassy metal alloy strips having a high specific strength comparable to anisotropic fibers used in high energy density flywheels and, in addition, having isotropic or nondirectional strength properties allowing a fuller utilization of the strength of the material and thereby increasing energy storage capacities. The glassy metal alloy strips are formed into circular layers, and a plurality of layers are joined concentrically to build up the flywheel. Joining between strips and layers is accomplished with bonding means such that a substantially mechanically monolithic composite structure results, by providing a bonding shear strength at least about equal to the specific strength times the density divided by the aspect ratio of the glassy metal alloy strips.
