    摘要: A sensing device for the direct conversion of analogue temperature information to fluidic analogue or digital pressure information. A thermally deformable element is disposed so as to apportion a fluid stream, issuing from a nozzle into an interaction region, into one or more fluid outlet passages as a function of the temperature sensed by the element. The outlet fluid pressure is thereby varied as a function of temperature, which temperature is generated by the fluid, a medium being tested by the element, or an electrical current flowing in a resistance path in thermal contact with the element.

    摘要: A fluidic accelerometer and electromagnetic transducer formed from a plurty of vertical laminations having a nozzle, a pair of outlets for receiving nozzle fluid and a flexible member as an extension of one of the laminations which forms a vertical wall of said nozzle extending into a chamber between the nozzle and the outlets. The flexible member is responsive to acceleration or electromagnetic forces transverse the nozzle centerline to vary the proportion of nozzle fluid received by each outlet. The flexible member is separated from the horizontal walls of the chamber by a selected small distance to create sufficient viscous shear force to effectuate damping.

    摘要: AN ELECTROMECHANICAL FLUIDIC TRANSDUCER HAS A FLOW FEED LINE COMMUNICATING WITH TWO FLOW OUPUTS. TWO CONTROL SIGNAL RESPONSIVE ELECTROMAGNETIC DEVICES ARE OPERABLE TO SELECT THE FLOW OUPUT, EACH CONTROLLING FLOW RELATIVE TO A RESPECTIE OUTPUT. A SIGNAL FLOW SWITCHING ELEMENT IS MOVABLE, UNDER THE INFLUENCE OF FLUID FLOW, INTO FLOW BLOCKING RELATION IN A SELECTED ONE OF THE FLOW OUTPUTS, AND THE SWITCHING ELEMENT IS LOCKABLE IN ITS BLOCKING POSITION BY THE ASSOCIATED ELECTROMAGNETIC DEVICE. THE FLOW SWITCHING ELEMENT IS A FORKED ELEMENT, AND EITHER MAY BE PIVOTED AT THE FORK BETWEEN THE TWO OUTPUTS OR MAY BE FLEXIBLE, IN THE FORM OF A LEAF SPRING. ADJUSTMENT CANALS OR DUCTS COMMUNICATE WITH THE FLOW FEED OR SUPPLY LINE FROM OPPOSITE SIDES TO COMPENSATE FOR ASYMMETRY OF THE FLOW CONTROL ELEMENT.

    摘要: In a multilayer sandwiched-type of construction, an operator activated by at least one pressure chamber is brought through a sealing configuration which also provides for pivoting of the operator; the operator itself is formed from a layer of the sandwiched construction and the sealing at the operator pivot is formed from sealing layers of the sandwiched construction; the operator layer may be backed by a resilient sheet layer for sealing the pressure chamber actuating the operator; this construction may be readily adapted to a plurality of pressure chambers employed in conjunction with motion-sensing devices, or alternatively weight and springs, to perform the functions of alarms, relays, repeaters, amplifiers, and a variety of other pneumatic devices.

    摘要: A pair of elements each incorporate vibrating reed means for producing an oscillatory output at a predetermined frequency; the oscillatory output from the two elements are effectively beat together by a fluidic amplifier to thereby produce a resultant signal having an envelope whose frequency is the difference between the respective frequencies produced by the two oscillatory elements; a signal corresponding to this envelope may be obtained from the fluidic amplifier output by suitable filtering to thereby produce a square wave having a stable interval; this square wave output may be employed for timing and clock functions in fluidic systems.
