  • Patent number: 10060118
    Abstract: Certain exemplary embodiments can provide deck bracket, which comprises a bracket face. The bracket face is substantially planar and defines a first plane. The deck bracket comprises a first bracket wall and a second bracket wall, each of which directly contact the bracket face. The deck bracket comprises a first bracket flange that directly contacts the first bracket wall and a second bracket flange that directly contacts the second bracket wall.

  • Publication number: 20070110991
    Abstract: A method of forming a hydrogen transport membrane to separate hydrogen from a hydrogen containing feed in which a porous ceramic support is formed to support a dense layer of palladium or an alloy of palladium serving as a hydrogen transport material. Isolated deposits of palladium, a palladium alloy or a component of such alloy are produced on a surface of the porous ceramic support that bridge pores within the porous ceramic support without penetrating the pores and without bridging regions of the surface defined between the pores. The isolated deposits of the metal are produced by an electroless plating process that involves contacting the porous ceramic support with a precipitating agent so that the precipitating agent fills the pores but does not seep out of the pores onto the regions of the surfaces defined between the pores. The surface is then contacted with a salt solution containing a salt of the metal so that said metal precipitates and produces the isolated deposits of the metal.

  • Publication number: 20060038399
    Abstract: A fitting for collecting or distributing high-pressure fluid via fluid transmission lines is provided. The fitting includes a body, and a plurality of apertures formed in the body in a common plane, intersecting inside the body such that all of the apertures are in mutual fluid communication. Each of the apertures is configured to receive a threaded coupling member of a respective high-pressure transmission line. The fitting also includes first and second compression members positioned on opposing sides of the body and coupled thereto so as to exert a compressing bias to the body in an axis perpendicular to the common plane. The compression members each comprise a raised contact surface corresponding to the region of the body where the plurality of apertures meet, and through which the compressing bias is exerted. The fitting may be an elbow-fitting, a tee fitting, a cross-fitting, or some other configuration.

  • Publication number: 20050074350
    Abstract: A pressure enclosure includes a first component having an opening, a second component coupled to the first component in a position over the opening, a third component positioned between the first and second components and covering the opening, and a load chamber defined by a space between the second and third components and configured such that pressure in the load chamber biases the third component against the first component to seal the opening. The pressure enclosure may be a cylinder of a pump for pressurizing fluid or gas, with the first component a cylinder body, the second component an end cap and the third component a valve body, with the load chamber biasing the valve body against the cylinder body.
