  • Fluid flow equalizing valve arrangement
    Patent number: 4325400
    Abstract: A fluid flow equalizing valve has two coupled valve devices for controlling flow to or from a common connection to respective ones of a pair of actuators. Control elements of the valve devices are responsive to intermediate pressures in flow paths to or from the actuators, and move in unison to reduce any difference in the intermediate pressures, and thereby to maintain the flows to or from the respective actuators substantially equal.

  • Drive arrangement for lift control surfaces on all aircraft wings
    Patent number: 4260121
    Abstract: A drive arrangement for lift control surfaces on an aircraft wing has a drive motor and a shaft for transmitting motion from the motor to the lift control surfaces. A control circuit is responsive to the driving positions of both the motor and the shaft, and is responsive to a predetermined level of discrepancy between these positions to operate one or more braking devices which restrain the shaft against movement.
