  • Patent number: 4349428
    Abstract: A flow-by anode is disclosed made by preparing a liquid suspension of about to about 18% by weight solids, the solids comprising about 3.5 to about 8% of a powdered catalyst of platinum, palladium, palladium oxide, or mixtures thereof; about 60 to about 76% carbon powder (support) having a particle size less than about 20 m.mu.m and about 20 to about 33% of an inert binder having a particle size of less than about 500 m.mu.m. A sufficient amount of the suspension is poured over a carbon cloth to form a layer of solids about 0.01 to about 0.05 cm thick on the carbon cloth when the electrode is completed. A vacuum was applied to the opposite side of the carbon cloth to remove the liquid and the catalyst layer/cloth assembly is dried and compressed at about 10 to about 50 MPa's. The binder is then sintered in an inert atmosphere to complete the electrode. The electrode is used for the oxidation of sulfur dioxide in a sulfur based hybrid cycle for the decomposition of water.

  • Patent number: 4346131
    Abstract: A clear solution is prepared by reacting metal alkoxide with a mixture of critical amounts of water and/or acid in an alcohol diluted medium. Alkoxides may be Ti(OR).sub.4 or Ta(OR).sub.5, or another metal alkoxide such as Si(OR).sub.4 in admixture with these alkoxides. Acids may be HCl or HNO.sub.3. Quarter wave inorganic optical coatings are deposited by applying the alkoxide solution to a substrate then heating the coating at over 350.degree. C. The coatings reduce reflectivity on silicon solar cells. The index of refraction of the coating can be varied by several techniques, including altering the proportion of titanium and silicon in the coating firing temperature, firing atmosphere. Thicknesses of the coating can be controlled by varying the rpm in spin application, withdrawal rate in dipping application, by concentration of the solution, by the type of solvent or the degree of polymerization of the titanium complexes.

  • Patent number: 4323540
    Abstract: The precipitation of an iron complex is reduced during the stripping of uranium with ferrous ion, where the uranium was oxidized with nitric acid then extracted with an organic solvent. The reduction is accomplished by pre-stripping with sufficient ferrous ion to reduce nitrates and nitrites formed during the nitric acid oxidation. The amount of ferrous ion used in pre-stripping, however, is insufficient to precipitate uranium.

  • Patent number: 4314779
    Abstract: A method is disclosed for restoring a clay rich aquifer which has been solution mined with ammonium ions. Calcium carbonate is precipitated from a solution pumped through the aquifer by the addition of calcium oxide, calcium hydroxide, or a mixture thereof in quantities sufficient to raise the pH to at least about 9.5. The precipitated calcium carbonate is separated from the solution and the ammonium ion is then removed from the solution by standard techniques. The solution is recycled through the aquifer and these steps are repeated until the bicarbonate ion concentration has been reduced to such an extent that the addition of at least one soluble salt of calcium, magnesium, or potassium to the solution does not result in precipitation of calcite underground, plugging the aquifer. Recycling with the addition of the soluble salt is continued until the ammonium ion concentration is reduced to a desired level. Finally, residual amounts of the salt are removed from the aquifer using standard techniques.

  • Patent number: 4312638
    Abstract: A process for gasifying coal and other carbonacaeous matter is disclosed which produces fuel gas containing low concentrations of polycyclic aromatic hydrocarbons. In this process the polycyclic aromatic hydrocarbons released by the coal during devolatilization and formed during pyrolysis of volatile matter are decomposed thermally in the presence of hydrogen, at a sufficiently high partial pressure (obtained by increasing the total pressure in the gasifier) to prevent polymerization of free radicals formed during pyrolysis. A relationship between the temperature, the gas residence time in the gasification reactor, the hydrogen partial pressure (i.e., total pressure in the gasifier), and the coal feed conditions are specified to achieve "clean" coal gasification.

  • Patent number: 4272988
    Abstract: A composition is disclosed of a solution of a resinous carrier and at least two compounds which thermoparticulate at different temperatures between 60.degree. and 200.degree. C. A coating is made by applying the composition to a portion of an electrical apparatus exposed to a gas stream. As the temperature of the coating increases the compound therein thermoparticulate. The time between which the compounds thermoparticulate indicates the rate of rise of the temperature and analysis of the products of thermoparticulation indicates the location of the coating in the electrical apparatus. Alternatively, the coating can consist of several layers with a thermoparticulating compound in each layer which thermoparticulates at different temperatures.

    Abstract: A mirror is made by applying a coating to a highly reflective surface of a substrate. The coating is prepared from a composition of an alkoxide having the general formula M(OR).sub.n, where M is 0 to 100% titanium, 0 to 25% silicon, 0 to 100% tantalum, or 0 to 15% of a metal ion which forms an alkoxide, R is alkyl from C.sub.1 to C.sub.6 and n is the valence of M, about 1.7 to about 8 moles of water per mole of alkoxide, sufficient alcohol to give a solids content of about 0.5 to about 15%, and a sufficient amount of a suitable acid to prevent cloudiness. The coated substrate is fired at about 200.degree. to about 600.degree. C. to form an oxide coating which is substantially oxygen impervious. Additional layers of the coating may be applied and fired until the oxide coating is about 200 to about 5000A thick, avoiding quarter-wave thicknesses.

  • Patent number: 4265861
    Abstract: A method is described for reducing the volume of radioactive waste produced during the solution mining of uranium and for recovering uranium from it. The recovery leach, which contains uranium in solution and is supersaturated with calcium carbonate, is treated with bicarbonate and made basic which precipitates calcium carbonate and some of the uranium. The precipitated calcium carbonate is dissolved with acid and the uranium in the solution is removed by extraction or precipitation. The remaining solution is contacted with sulfate ions and barium or strontium ions to precipitate BaSO.sub.4.RaSO.sub.4 or SrSO.sub.4.RaSO.sub.4, the principal radioactive constituent in the solid waste product.
