Abstract: High tensile strength, creep and corrosion resistant zirconium alloys containing 7.0-10.0 wt % aluminum, 0-3 wt % in total of one or more elements selected from the group consisting of magnesium, tin, chromium, iron, carbon, silicon, yttrium, niobium, molybdenum and beryllium, the balance zirconium and incidental impurities, are produced by annealing cast alloys at a temperature below about 992.degree. C. for a period of time sufficient to produce alloys having a substantially continuous matrix of the ordered intermetallic compound Zr.sub.3 Al. The alloys may initially be hot worked at temperatures about 1000.degree. C., while in the .beta.Zr-Zr.sub.2 Al two phase region, prior to annealing. Preferred alloys contain 7.5-9.5 wt % aluminum, the balance zirconium and incidental impurities.

Abstract: A support for mounting an electrical outlet box in an aperture in a building panel, said support comprising a U-shaped yoke having a base portion, a pair of legs substantially normal to the base portion and a support foot extending outwardly from each leg substantially parallel to the base portion and adapted to overlie an area of the front of the building panel adjacent the aperture when the yoke is inserted in the aperture, each leg having at least one aperture intermediate the base portion and the foot; and a clamping member for association with each leg of the yoke, each clamping member having a support surface adapted to overlie an area of the back of the building panel opposite the area of the front of the building panel to be overlaid by the foot of the associated leg, a tab member extending from said support surface and adapted to interconnect the clamping member with said at least one aperture of the associated leg, and a clamping arm extending from the support surface on each side of the tab member,

Abstract: A method for preventing greening due to chlorophyll formation in raw unpeeled cold-stored potato tubers exposed to light prior to and including retail sale which comprises spraying or dipping the tubers in an aqueous emulsion containing a single surfactant so as to form a thin continuous film in and on the surface of the tuber which is relatively impermeable to carbon dioxide thereby ensuring an atmosphere containing at least 15% CO.sub.2 within the film and in the tuber. The surfactant preferably contains long chain fatty acid moieties and polyoxyalkylene or polyhydroxy moieties, and has an HLB rating below about 15. A modified process involves the addition of an organic acid, selected from aliphatic mono- and polycarboxylic acids having from 2-6 carbon atoms and at least one hydroxy or oxo group, and lactones thereof, excepting those dicarboxylic acids which readily form internal anhydrides, to the surfactant mixture in order to "tighten" the surfactant film formed on the tubers under treatment.

Abstract: A cathode for use in a hydrazine/air fuel cell which comprises a sintered nickel substrate having a silver electrocatalyst deposited thereon and having, on one side, a semipermeable hydrophobic membrane, and on the other side thereof a hydrophilic microporous separator membrane. The silver-sintered nickel substrate may be wet-proofed by dipping in a solution of PTFE and in order to lower polarization of the cathode the silver-sintered nickel substrate may be amalgamated by treatment with a mercuric salt.

Abstract: A gasoline preheater for an internal combustion engine, comprising a coil of copper tubing through which gasoline is passed prior to supply to an internal combustion engine for combustion, said tubing coil being in tensioned contact about a copper cylinder through which internal combustion engine coolant is passed and fixed adjacent each tubing coil end to the cylinder, and wherein the cylinder contacting tubing of the tubing coil has a cross-sectional configuration substantially that of a centrally waisted ellipse.

Abstract: An ear-type livestock identification tag comprises a planar member having a body and a neck, the neck extending outwardly from the body and adapted for insertion through an animal ear, and a tab member adapted for locking onto the terminal end of the neck. The curvature and length of the neck is such that the body of a tag having the neck mounted, close to the head, in an animal ear lies below the ear and roughly parallel to the animal's cheek. Identifying indicia on the tag body is easily read since the body lies parallel to the cheek, and there is little accidental tag loss since the neck is anchored in a thick part of the ear.

Abstract: A process for upgrading an ilmenite concentrate by agglomerating the ilmenite fraction and removing gangue materials such as complex silicates in an aqueous phase. An aqueous dispersion of the concentrate suitably ground to about 60% minus 400 mesh is formed, the pH is adjusted in the range of 4 - 5.5, 5-10 lbs./ton of a conditioner such as oleic acid is added, followed by 100-200 lbs./ton of a binder liquid such as a light petroleum oil, and the mixture agitated to cause ilmenite solids in the mixture to absorb the oil thus forming spherical oil-bonded agglomerates containing the ilmenite values. The silicate gangue is removed in aqueous tailings and the agglomerated product separated and further treated to recover pigment grade titanium dioxide.
