  • Patent number: 10816019
    Abstract: A hydraulic system (e.g., of an aircraft or other vehicle) includes a pump, a pressure line coupled to the pump and configured to distribute pressurized hydraulic fluid, and a return line configured to return hydraulic fluid to a reservoir. The hydraulic system also includes an auxiliary leakage valve coupled to the pressure line, to the return line, and to an actuator. The auxiliary leakage valve is configured to receive a control signal and, based on the control signal, selectively open a restricted fluid path. The restricted fluid path couples the pressure line to the return line to allow a restricted amount of the hydraulic fluid to flow from the pressure line to the return line.

  • Publication number: 20150276104
    Abstract: A method of joining two tubular sections including applying adhesive to a male end of a first tubular section and fitting the male end to a female end of a second tubular section. A clamp is positioned over the female end of the second tubular section and tightened to apply a circumferential inward force to the female end to reinforce the adhesive in securing the first tubular section to the second tubular section.
