  • Patent number: 7506516
    Abstract: A catalytic combustor (28) includes a tubular pressure boundary element (90) having a longitudinal flow axis (e.g., 56) separating a first portion (94) of a first fluid flow (e.g., 24) from a second portion (95) of the first fluid flow. The pressure boundary element includes a wall (96) having a plurality of separate longitudinally oriented flow paths (98) annularly disposed within the wall and conducting respective portions (100, 101) of a second fluid flow (e.g., 26) therethrough. A catalytic material (32) is disposed on a surface (e.g., 102, 103) of the pressure boundary element exposed to at least one of the first and second portions of the first fluid flow.

  • Patent number: 5517862
    Abstract: An apparatus and method for measuring discrete velocities of exhaust flows coming out of individual circumferential rotor body vent holes while a rotor is running at operating speed. The apparatus and method employs a hot film anemometer to measure flow distributions around the rotor shaft, i.e., circumferential flow distributions.

  • Patent number: 4516964
    Abstract: A power transmission chain-belt, especially adapted to provide a drive and transmit power between the pulley of a pulley transmission, such as a variable ratio pulley transmission. In such each pulley has a pair of flanges, at least one of which is axially movable with respect to the other. The chain-belt is constructed of a plurality of ranks or sets of interleaved links, each rank being joined to the next adjacent rank by pivot means, such as round pins, or a pin and rocker, to permit articulation of the belt. Generally trapezoidal-shaped load blocks are located between the pivot means of each rank or set of links, which blocks have opposite edge surfaces to drivingly contact the flanges of the pulleys. At least one load block has a different width than the other load blocks, so as to contact the flanges of the pulley at a different radial location and different time than the other load blocks.
