  • Publication number: 20080090097
    Abstract: The composition of matter includes an alloy formed by vaporization of either magnesium or iron in continuation with one or more metals. This results in an array of alloy members each making up the alloy and extending from a base to an upper end. A fluid at least partially impregnates the spaces between the alloy members to the surrounding areas. A dissolving cap can either be included or deleted to prevent the fluid from diffusing until the cap is dissolved.

  • Publication number: 20080047700
    Abstract: A formed sheet heat exchanger is provided for exchanging heat between fluids is provided. The apparatus includes flow divider sheets that are positioned in a stacked configuration and extend in a longitudinal direction so that adjacent pairs of the sheets define flow passages therebetween for receiving first and second fluids. Each of the sheets is nonuniform in the longitudinal direction, having a manifold portion and a corrugated portion. The corrugated portions of each adjacent pair of sheets define a plurality of fluid channels therebetween that are connected to the portion of the flow passage defined between the manifold portions. The fluid channels are configured to receive the first or second fluids and transfer thermal energy therebetween through the flow divider sheets.

  • Publication number: 20060124448
    Abstract: The invention relates to novel sensors of the catalytic gas-sensing thin-film metal surface type wherein the surface has an inorganic protective membrane coating formed by a pulsed dc sputtering technique. Preferably, the thin-film metal surface is a Pd, Pt, Ni, Au, Ag or an alloy thereof. The inorganic membrane is of the formula MaObNcCd where M is a metal or semiconductor, O is oxygen, N is nitrogen, and C is carbon and a, b, c, and d can each independently range from zero to seven with the proviso that at least two of a, b, c, and d are non-zero. The sensor design is particularly useful for various hydrogen sensing applications. The invention also includes their method of manufacture.

  • Publication number: 20050188703
    Abstract: An air/fuel pre-mixer for a gas turbine combustor and a method of pre-mixing air and fuel for a combustor are provided. In one embodiment the pre-mixer includes a first annular premix fuel manifold disposed upstream of the combustor and an annular member concentric with the first premix fuel manifold. Together the annular premix fuel manifold and the annular member define a first venturi shaped air/fuel pre-mix volume between them that has a throat. At or upstream from the throat, the first premix fuel manifold has a plurality of pores whereby the fuel is injected from the first premix fuel manifold to mix with air in the first pre-mix volume. In another embodiment, the annular member is an outer wall, whereas in yet another embodiment, the annular member is a second premix fuel manifold.
