  • Dual stage pressure relief valve
    Patent number: 10871237
    Abstract: A dual stage pressure relief valve for relieving pressure. The pressure relief valve includes a main body, a poppet bulb, a pilot piston, and a poppet cap. The main body defines a main channel that extends from a first opening to a second opening. The poppet bulb defines a first flow channel being in fluid communication with the main channel. The pilot piston defines a reset channel in fluid communication with the first flow channel of the poppet bulb. The cap channel has a diameter that is greater than a diameter of the reset channel. The poppet cap defines a cap channel in fluid communication with the reset channel of the pilot piston and with a pressure cavity defined by the poppet cap and an end of the main body.
    Type: Grant

  • Aerial refueling hose
    Patent number: 9631744
    Abstract: An in-flight refueling hose and method. The hose includes an inner braid including pseudoelastic shape memory alloy (e.g., nitinol) wires. These wires undergo a stress induced phase change absorbing energy to dampen oscillations of the hose in use.

  • Method and apparatus for thermally activated sprinklers
    Patent number: 9180326
    Abstract: A sprinkler head including a sprinkler body with a passage for fluid and a seal mechanism sealing the passage, and a cage member. A frangible bulb extends between the cage member and the seal. A shape memory alloy element is associated with the frangible bulb and has a first configuration that fits within, about, or abutting the bulb and a second configuration at a predetermined temperature which breaks the frangible bulb releasing the fluid through the passage.
