  • Patent number: 4004573
    Abstract: For collection, retrieval, and utilization of solar energy, there is taught a process and an apparatus wherein a photochemical fluid, containing an isomerizable compound, is passed through a collector for exposure to solar radiation to transform the isomerizable compound to a higher energy level isomer. The irradiated fluid leaving the collector passes in heat exchange relationship with photochemical fluid entering the collector and then proceeds into a trigger reactor means. In the trigger reactor means, higher energy level isomer in the irradiated fluid is triggered, such as by heat and/or catalyst contact, to revert to an isomerizable composition of a lower energy level isomer with exothermic release of heat in excess of that requisite for maintaining conversion of higher energy level isomer to lower energy level isomer.

  • Patent number: 3997582
    Abstract: A gaseous (C.sub.1 to C.sub.4) hydrocarbon mixture having a high methane content (at least 80 percent by volume on a carbon dioxide-free basis) is obtained by passing a mixture of hydrogen and carbon monoxide at a volume ratio of about 47:53 to 60:40 at a temperature between about and about C. and a pressure of about 200 p.s.i.g. to about 10,000 p.s.i.g. at a volumetric space velocity of about 500 to about 6000 in contact with a sulfur resistant catalyst comprising an interspersed mixture of cobalt oxide, aluminum oxide and zinc oxide. The catalyst comprises about 1 to about 15 weight percent of cobalt oxide, about 15 to 60 weight percent of aluminum oxide and about 35 to about 70 weight percent of zinc oxide.

  • Patent number: 3990953
    Abstract: Elemental silicon of utility as a corrosion resistant coating, as an absorber in a solar thermal conversion system, etc. is provided by nonaqueous electrolytic deposition thereof on a cathode body through electrolytic reduction of a silicon halide or haloid silane compound as a solute in a liquid aprotic dipolar organic solvent for the compound by passing therethrough an electrolyzing current, generally at near ambient temperature and near atmospheric pressure yet under cover of an inert gas, and desirably by pulse electrolysis. The electroplating composition consists essentially of a nonaqueous solvent solution of the anhydrous liquid aprotic dipolar organic solvent, for example propylene carbonate, dimethylformamide, etc., containing the silicon solute, such as illustrated by silicon tetrachloride and trichlorosilane, in an amount providing, or providing by inclusion therewith of a dissociable electrolyte (e.g.

  • Patent number: 3986885
    Abstract: A method of making a two-phase material comprising a mix of concrete and fibers of a material having a modulus of elasticity of at least about 20 million psi substantially uniformly distributed therein with an average spacing between fibers of up to about 0.3 inch. The flexural strengths are measured for a plurality of substantially different average bond areas of the fibers per unit area in planes normal to tensile stress in test specimens of the two-phase material, and the fibers are provided and distributed in such quantity in the bulk mix that the average bond area of the fibers intersecting planes normal to the stress at known regions of highest tensile stress is sufficient to provide at least a preselected flexural strength in such regions.

  • Patent number: 3953610
    Abstract: The pH of milk is lowered to 4.5 to 5.5 by direct acidification without the necessity of cooling the milk to avoid local coagulation and casein precipitation by adding acid as a spray from above a portion of the milk surface undergoing high velocity mixing.
