  • Patent number: 11892165
    Abstract: A heat shield for a fuel nozzle of a gas turbine engine combustor. The heat shield includes a radial flange extending in radial and circumferential directions and has an opening therethrough at a radially inward end of the radial flange, and an annular conical wall extending in longitudinal and circumferential directions, the annular conical wall being connected to the radial flange at the radially inward end of the radial flange. The radial flange includes a flange forward side, and a flange aft side, and has a flange outer end portion. The flange outer end portion includes a flange rounded end portion on one of the flange forward side or the flange aft side, and a flange rounded protruding lip on the other of the flange forward side or the flange aft side, the rounded protruding lip extending in the longitudinal direction.
    Type: Grant
    Filed: May 19, 2021
    Date of Patent: February 6, 2024

  • Patent number: 10000638
    Abstract: This invention relates to a storage stabilized recycled and devulcanized tire rubber modified asphalt composition, which comprises: 65.0 to 90.0% by weight of a neat asphalt, 3.0-50.0% by weight of a recycled and devulcanized rubber from used tires and/or other scrap rubbers, 0.01-15.0% by weight of a compatibilizer/stabilizer derived from Natural or Synthetic Rubbers, which composition passes the “cigar tube” softening point test difference of less than 5° C. between the top and bottom layers; and, the process for the said asphalt composition comprises mixing 65.0% to 90.0% by weight of a neat asphalt, 3.0 to 50.0% by weight of a recycled and devulcanized rubber from used tires, 0.01-10.0% by weight of a compatibilizer/stabilizer derived from Natural or Synthetic Rubbers, using high shear mixers at elevated temperatures of between 120° C. and 175° C. for between 15 minutes to 6 hours, to obtain storage stabilized asphalt composition that is stable in hot storage and transportation conditions.
