摘要： A pressure fluid impulse converter for transforming primary pressure fluid impulses of a higher frequency into secondary pressure fluid impulses of a lower frequency, comprising a hydraulically actuated activating means arranged to cause a valve in a pressure fluid circuit to shift from a closed to an opened position and a positive displacement pump which is actuated by the primary pressure fluid impulses and arranged to feed motive hydraulic fluid to said activating means. The latter is thereby stepwise displaced from a rest position to a valve activating position.

摘要： The present invention provides a simple and effective method and apparatus for hydraulically suspending a vehicle seat while regulating movement of the seat in response to vertical travel of the vehicle, a reciprocable power piston within a cylinder comprising a flexible coupling between the seat and a suitable support structure, a control valve selectively communicating a source of fluid with the cylinder in response to pressure variations developed by movement of the power piston within its cylinder. The invention also preferably includes load compensating means for limiting the control function in response to relatively minor movement of the piston as well as a damped leveling unit partially formed by the power piston for providing hydraulic response to limited movement of the piston.

摘要： The subject circuit has a source of fluid pressure, a bistable fluidic amplifier, an indicator moved by fluid impulses from the amplifier when count signals are applied thereto, a plurality of ''''not'''' elements for supplying fluid impulses to the control ports of the bistable amplifier, a ''''one shot'''' element for directing actuating signals to the ''''not'''' elements when the fluid pressure source is re-energized after being shut off, and means, dependent upon the indicating position of the indicator, to block the actuating signal to a certain ''''not'''' element whereby a predetermined control port of the amplifier will be precluded from receiving an impulse and the indicator will remain in the same indicating position it occupied when the power source was shut off until the next succeeding count signal is applied to the bistable amplifier.

摘要： A pneumatic signal limiter includes an integrated fluidic repeater and variable restrictor assembly having a pair of telescoping interconnected input and output body members with opposing and complementary recessed faces defining an input chamber and an output chamber to opposite sides of a diaphragm. The output portion includes an exhaust orifice and passageway within which a variable low limit restrictor is mounted to control the exhaust flow. The output body further includes an output passageway and intersecting exhaust passageway with an adjustable high limit restrictor connected directly to the exhaust passageway. The supply is connected to the output passageway in series with a restrictor through the intersecting passageway or a separate connection. Each restrictor is a needle valve which is adjustably secured within the housing with a conical point within a related limiter orifice. The threaded pin valve member has a relatively small cone angle and very fine adjusting threads. A closed loop control system includes a controller connected to sensors from a controlled variable source and from a master variable source through limiters. The controller is connected via a limiter to a control apparatus for the controlled variable unit.

摘要： Pneumatic instrumentation apparatus of the planar type comprising a laminar sandwich construction one layer of which is a stiffly-flexible metal plate formed with cut-out openings to define an interior flat operator pivotally and sealingly supported at intermediate pivot axis region. The operator includes two separate but integral sections, located on opposite sides of the pivot axis. One of these sections is sub-divided into a plurality of separate side-by-side segments each integral with the pivot axis region, and arranged to supply separate torques to such pivot axis, or to move therewith in response to forces applied by other segments of the operator. Such multisegmented pivotable operator is embodied in a variety of instruments, including process controllers, a ratio unit, and a digital-to-analog converter.

摘要： This disclosure includes a fluidic linear accelerometer in the form of a looped conduit of substantially lineal configuration having a fluid input supply and terminating in a pair of opposed ends. A summing impact modulator is connected to the conduit ends to provide an amplified fluidic signal. The density of the fluid flowing in one of the two lineal passageways forming the loop is changed with respect to the other. A pressure differential is established which is dependent upon the linear acceleration in the lineal direction and the difference in densities.
