  • Patent number: 8357284
    Abstract: A metal film-forming method is capable of forming a metal film on a surface of a base metal film, formed on a surface of a substrate, with sufficient adhesion to the base metal film even when a natural oxide film is formed on the surface of the base metal film. The metal film-forming method includes: preparing a substrate having a base metal film formed on a surface; and carrying out electroplating of the substrate using the base metal film as a cathode and another metal as an anode while immersing the substrate in a solution containing a metal complex and a reducing material, both dissolved in a solvent, to form a metal film, deriving from a metal contained in the metal complex, on the surface of the base metal film.

  • Patent number: 7977518
    Abstract: A process and system for converting organic waste into reusable hydrocarbon is described wherein the process includes feeding an organic waste into a pyrocatalytic reactor which is essentially free of halogenated synthetic resinous material into a molten lead bath which is confined in a reactor in an substantially oxygen-free atmosphere which is admixed with a catalytic material comprising particulate aluminum oxide and aluminum powder. The waste is thermally and catalytically converted with at least 50% effectiveness to produce a reusable hydrocarbon.

  • Patent number: 7563345
    Abstract: A system for pyrocatalytic conversion of non-halogenated synthetic resinous material is reacted in a molten lead bath in an oxygen free environment, wherein the non-halogenated resinous material is mixed with a particulate catalyst in the lead bath which is at a temperature in the range from about 450° C. to 55° C., wherein the non-halogenated resinous waste is thermally and catalytically converted with at least 60% effectiveness into reusable hydrocarbons which are removed as vapor form the molten lead bath and recovered as useable hydrocarbons.

  • Patent number: 7285186
    Abstract: A process for converting organic waste into reusable hydrocarbons and a system for doing so, the system including a feeding mechanism for the waste, a reactor and a residue-disposing mechanism. The waste is to be fed into the reactor in which a molten lead bath is confined in an oxygen-free atmosphere. The system is used to practice a process for the pyrocatalytic conversion of the waste, which process comprises, feeding the waste into a reaction zone of a pyrocatalytic reactor, the waste being essentially free of a halogenated synthetic resinous material, and mixing the waste with a minor proportion by weight of a particulate catalyst in the bath held at a temperature in the range from about 450° C. to 550° C. in an elongated vat. The catalyst consists essentially of a major proportion by weight of particulate bauxite <2 mm, in combination with a minor proportion of aluminum powder <0.

  • Patent number: 6017214
    Abstract: An improved non-recovery coke oven floor constructed of a single layer of refractory bricks including, for each oven sole flue, a pair of trunnion bricks and a center bridge brick spanning the width of the flue, having lower brick surfaces in the form of an arch, and joined end-to-end by a tapered tongue-and-groove joint disposed approximately perpendicular to the direction of a compression load transmitted by the center bridge brick to the trunnion bricks.

  • Patent number: 4564420
    Abstract: Coking chambers in a coke oven battery are disposed in an alternate relationship with heating flues. At the top of each coking chamber there is a top arch having an inner-arched surface defined by a segment of a circle whose diameter is greater than the internal width of the coking chamber. The coking chamber is bounded by two heating walls which are extended to the spring of the arch where wall portions extend in an inclined manner upwardly and outwardly to form a mushroom-shaped gas-collecting chamber above the coke oven chamber. These wall portions extend at an angle of approximately 30.degree. to 50.degree. to the horizontal. The diameter of the arched wall portions for the arch is approximately between 30% and 60% greater than the internal width of the coking chamber.
