    Patent Number:
    US 7922845 B2
    Description:

    An apparatus for bonding a first carbon composite to a second carbon composite through a reactant layer includes a housing, and a pair of conductive press plates electrically isolated from the housing. The press plates are adapted to position the two parts to be bonded with a reactant layer therebetween. The press plates are subjected to an electrical potential and a clamping force, sufficient to initiate a combustion reaction that creates a molten ceramic to bond together the carbon-carbon c…

    Patent Number:
    US 6428754 B2
    Description:

    An exhaust gas treatment system and method for treating the exhaust gas of an internal combustion engine includes a catalytic converter and a catalytic preheater or igniter upstream of the catalytic converter. A bypass passage extends around the igniter such that during the ignition period about two-thirds of the exhaust gas is bypassed around the igniter and one-third passes through the igniter. The igniter raises the temperature of the exhaust gases passing therethrough to an adiabatic temp…

    Patent Number:
    US 5312679 B2
    Description:

    A catalytic carbon formation technique in a carbon fiber substrate is disclosed. The carbon fiber substrate is first impregnated with a catalyst and is thereafter heated in an atmosphere rich in carbon and hydrogen. The catalyst is typically a Group VIII metal and may be selected from the group consisting of iron, nickel and cobalt. An incipient wetness technique for impregnating the substrate is also disclosed. A salt of the catalyst is provided in solution and void volume of the substrate i…

    Patent Number:
    US 6869671 B2
    Description:

    A thin film based nanoporous alumina template has been developed which allows the in situ removal of an electrically insulating alumina barrier layer at the pore bases. This barrier free nanoporous system has great utility for electrodeposition of a wide variety of nanowire materials. An exemplary multilayer thin film precursor is provided comprising Al (anodization layer), Ti (diffusion barrier) and Pt (active electrode) on a Si substrate. Aluminum anodization in sulfuric acid with a subsequ…

    Patent Number:
    US 6896846 B2
    Description:

    A method for synthesis of biomedical alloys has been developed based on combustion phenomena. This low pressure combustion synthesis (LPCS) technique may be used for production of Co-based and other metal-based alloys, which cover the entire range of orthopaedic implants, including total hip and knee replacements, as well as hone screws, plates, and wires. A unique aspect of the method is that combustion synthesis under low ambient gas pressure allows one to produce pore-free (>99% theoret…

    Patent Number:
    US 5286698 B2
    Description:

    Solid oxide solutions of the formula La.sub.1-x Sr.sub.x CrO.sub.3-.differential. have been found to exhibit surprisingly high specific activity as catalysts for oxidation and hydrogenation reactions. The oxide solutions can be utilized in particulate form or applied as films to the surfaces of refractory substrates. The oxide solution catalysts are expected to be a viable alternative to the noble metal catalysts now used commercially for treatment of combustion chamber exhaust gases to reduc…

    Patent Number:
    US 8356475 B2
    Description:

    Described is a method of slowly releasing a catalyst for, inter alia, the purpose of soot oxidation in a particulate filter. An example method includes incorporating an alkali metal oxide in a glass. Slow leaching of the alkali from the glass provides a means to gradually deliver the catalyst over extended periods. Additionally, the example method includes increasing the amount of alkaline metal ions that may be leached from the glass.
