| 81 | Fluid pressure governor valve | US3789863D | 1971-12-07 | US3789863A | 1974-02-05 | ENOMOTO K; OHTSUKA K; ISHIMARU W |
| A fluid pressure governor valve adapted to produce a pressure signal that is proportional in magnitude to the speed of rotation of an output shaft of an automotive power transmission having a parking lock gear mounted for rotation with the output shaft, which governor valve consists of a valve body formed by a convex portion of the parking lock gear, first and second valve chambers formed in the convex portion of the parking lock gear, first and second passages formed in a disc portion of the parking lock gear and respectively communicating with the first and second valve chambers, and first and second drain ports formed in the convex portion of the parking lock gear and respectively communicating with the first and second valve chambers. The governor valve further consists of a primary governor valve element and a secondary governor valve element, which are radially movably accommodated in the first and second valve chambers, respectively. The primary and secondary governor valve elements are associated with each other for thereby producing a pressure signal that is proportional in magnitude to the speed of rotation of the output shaft.

| 82 | Reversing pneumatic amplifier | US3710825D | 1971-08-13 | US3710825A | 1973-01-16 | OTTENI H |
| There is disclosed a reversing pneumatic amplifier including a valve ball movable in a sleeve for opening or closing a control slot provided circumferentially in the sleeve in a radial plane thereof. The valve ball is displaced in one or the other direction when a pilot pressure, indirectly exerting a force to the ball through a bellows and a push rod, exceeds or drops below a predetermined value. Said force is opposed by a supply pressure directly affecting the valve ball. Dependent upon the direction of displacement of the valve ball, the output pressure of the amplifier is either increased or decreased.

| 83 | Thermal compensator valve for differential pressure devices | US3687160D | 1970-10-21 | US3687160A | 1972-08-29 | ERICKSON RODNEY R; MATTHEWS RALPH W; SPRANGEL RICHARD V |
| A hydraulic control system employing pressure differentials for control functions will maintain uniform pressure differentials over a broad temperature range by incorporation of the thermal compensator valve connected in parallel with the pressure differential generating device so the fluid flow through the device is controlled as a function of temperature to maintain a constant output from a device for a given set of physical conditions. The valve itself includes an inlet and an outlet with a flow-control spool disposed in a passage therebetween to meter the fluid and a thermal responsive element connected to position the spool in response to fluid temperature whereby the output of the device will remain essentially constant for a given physical set of conditions regardless of the temperature of the fluid.

| 84 | Force-balance pneumatic regulator with resilient cross fulcrum, having high sensibility and precision and easy, continuous gain regulation | US3682048D | 1970-11-06 | US3682048A | 1972-08-08 | BERGAMINI GIORGIO |
| A pneumatic force-balance regulator is described that has a pair of bellows which respectively support members, movable in response to differences in the external and internal pressures on the bellows, that are connected through struts to a balance mounted to oscillate around a resilient cross fulcrum so that the regulator gain may vary with continuity and the axes of the struts lie in the plane containing the axis of oscillation of the balance so that parasitic forces, acting on the struts along their axes, do not affect the equilibrium of the balance.

| 85 | Acknowledge-monitor logic device with memory | US3631876D | 1969-09-15 | US3631876A | 1972-01-04 | MISEVICH KENNETH W |
| A fluid-operated logic device suitable for operating an annunciator system, or the like, which device has a bore with a piston valve member slidable therein. The piston has a transverse alert crossover to permit fluid flow between a constant pressure conduit and an alert conduit leading to an alert indicator. The piston is also provided with a crossover which permits communication between a conduit in which pressure increases in response to the detection of trouble and a monitor conduit leading to a monitor alarm. A conduit branches from the trouble conduit and is connected to the casing to act against the head end of the piston valve member. Upon an increase in pressure in the trouble circuit, the piston will be moved to the alert position where the alert alarm will be given until this condition has been acknowledged, the kinetic energy of the moving piston being employed. The piston is then returned to its normal position by an acknowledge arrangement, but should the trouble condition persist, the piston will return to and remain in its monitor position to indicate that the trouble condition has not been removed. When the trouble disappears, fluid pressure will move the piston to its normal position.

| 88 | Control apparatus having redundant condition-sensing means and failure indicator | US3592382D | 1969-11-19 | US3592382A | 1971-07-13 | BYRER BOYD P |
| A casing contains two fluid-pressure-responsive members each of which is responsive to an associated input fluid pressure which varies as a function of the same sensed variable condition. A servo valve actuated in response to the higher of the two outputs of the fluid-pressure-responsive members controls a servovalve which, in turn, establishes a control output which controlled servo pressure is applied to a separate feedback-fluid-pressureresponsive member associated with each of the two fluid-pressureresponsive members and connected to oppose the output thereof. A loss of input fluid pressure to either fluid-pressure-responsive member results in actuation of a visual failure indicator by the associated feedback-fluid-pressure-responsive member while the input fluid pressure to the remaining fluid-pressure-responsive member maintains the desired servo fluid pressure.

| 89 | Differential pressure responsive device with diaphragm equalization | US3563138D | 1969-06-23 | US3563138A | 1971-02-16 | SYMONDS JAMES A; CALLAHAN JOHN J |
| A pair of nominally identical diaphragms are rigidly interconnected with the end of a bar to deflect same. A connector on the end of the bar has an oblique circumferential track. Stems on the diaphragms are clamped in the track. To adjust for diaphragm differences, the stems are unclamped and the connector is rotated to shift the stems, the one stem moving toward the axis of bar deflection, and the other moving away therefrom. In this way, the difference between the diaphragms'' responses to pressure is neutralized by difference in effective lever arm of said diaphragms on said bar. The connector may be in the form of two like cylinders, each having nonparallel bases and clamping the stems between them.
