  • Electronic controller with off-load and anti-stall capability for Ram air turbine variable displacement hydraulic pump
    Patent number: 11820528
    Abstract: An aircraft hydraulic control system includes a pump system, a fluid circuit, and a controller. The pump system includes a hydraulic pump and a ram air turbine assembly. The fluid circuit delivers hydraulic fluid to the hydraulic pump and receives the hydraulic fluid output from the hydraulic pump. The controller is in signal communication with the hydraulic pump. The controller determines a rotational frequency of a ram air turbine included in the ram air turbine assembly, and controls the hydraulic pump so as to control the flow of hydraulic fluid in the fluid circuit. The flow of hydraulic fluid in the fluid circuit controls a fluid pressure of the aircraft.

  • Deactivatable security label for anti-theft systems
    Patent number: 4743890
    Abstract: A deactivatable security label comprising a low-coercivity strip and a strip having a high coercive field strength can be advantageously manufactured when the alloy of cobalt, nickle and/or iron is employed which exhibits a coercive field strength of between 20 and 50 A/cm given a remanence of more than one Tesla and when this strip is secured to a low-coercivity strip of amorphous material by means of spot welding.
