    摘要： A draining apparatus drains and dries hydraulic equipment such as aircraft circuits. The draining equipment includes a reservoir connected to the equipment by a suction line. (Venturi 20) which produces a vacuum in the reservoir responsive to compressed air injected by a line from an external compressed air source. If a calibrated valve is connected to an inlet of the equipment then a branch line of the equipment supplies part of the compressed air to the inlet connection of the equipment so that pressure which enters the equipment is inadequate to produce an overpressure at an outlet.

    摘要： A device is described for generating operating states characterized by dirences in height in actuators arranged in a matrix. In order to enable operating states which are characterized by differences in height to be produced in mechanical actuators in close matrix-type arrangement which are controllable selectively and independently from one another in a simple manner in a suitable device a reservoir filled with electroviscous liquid has an over-pressure chamber and a negative-pressure chamber and these chambers are connected via separate control ducts with hydraulic cylinders of the actuators, the connection to the two chambers of the reservoir being opened or blocked alternatively by the two control ducts of an actuator via a first electrode and a second electrode and a controllable center electrode common to both. The pressure variation formed in this way changes the vertical adjustment of a mechanical pin via an elastomer diaphragm. The device is used primarily for adaptive circuit board testers and for representing braille text.
