摘要： A FLUID PRESSURE PROBE SYSTEM FOR GENERATING A SIGNAL IN RESPONSE TO THE LOCATION OF AN ARTICLE AT A SELECTED POSITION AT A WORK STATION. THE SYSTEM INCLUDES A PLURALITY OF INDIVIDUAL DIFFERENTIAL RESPONSIVE TRANSDUCERS CONNECTED IN PARALLEL TO A COMMON PRESSURE MANIFOLD SO THAT MANIFOLD PRESSURE IS NORMALLY APPLIED TO BOTH SIDES OF EACH TRANSDUCER TO NORMALLY MAINTAIN A ZERO DIFFERENTIAL PRESSURE. A PROBE HAVING A VENT PASSAGE IS CONNECTED TO EACH TRANSDUCER BETWEEN ONE SIDE OF THE TRANSDUCER AND THE POINT OF CONNECTION TO THE MANIFOLD. THE OUTLET OF THE VENT PASSAGE IS NORMALLY CLOSED BY A SIMPLE BALL VALVE SEATED IN THE END OF THE PASSAGE AND MAINTAINED IN ITS CLOSED POSITION BY THE PRESSURE WITHIN THE PASSAGE. THE

PROBE IS MOUNTED IN THE WORK STATION AT A LOCATION SUCH THAT THE BALL IS UNSEATED BY THE ARTICLE WHEN THE ARTICLE IS IN THE DESIRED LOCATION, THUS CREATING A DIFFERENTIAL PRESSURE AT THE TRANSDUCER. A RESTRICTED ORIFICE IS LOCATED BETWEEN THE POINT OF CONNECTION OF THE VENT PASSAGE TO THE TRANSDUCER AND THE POINT OF CONNECTION OF THE TRANSDUCER TO ONE SIDE OF THE MANIFOLD TO PREVENT THE PRESSURE DROP PRODUCED BY THE VENTING FROM TRIGGERING ANY TRANSDUCERS OTHER THAN THE ONE TOW WHICH THE ACTIVATED PROBE IS CONNECTED.

摘要： A fluid cylinder and piston assembly for use in a fluid filter assembly or the like, which includes a housing and a cover; a spring-biased compound piston and cylinder assembly is reciprocable within the housing on a stationary guide rod attached to the cover of the housing. The compound piston and cylinder assembly defines a pressure chamber having a plunger attached to the end of the guide rod disposed therein and the chamber is in communication in front of the plunger with a fluid inlet in the cover by means of restricted passages to move the compound piston and the cylinder assembly in one direction and the plunger is constructed such as to permit metered amounts of fluid to the plunger within the cylinder at a predetermined fluid pressure to move the compound piston and cylinder assembly in the other direction.

摘要： A pneumatic controller provided with a flapper-nozzle assembly and an actuator-arm assembly. The flapper-nozzle assembly includes a flapper having a blade section and a flat tab section such that deflection of the tab section causes the blade section to move relative to the orifice of a nozzle to more or less throttle the rate of fluid flow through the nozzle. The flappernozzle assembly is rotatable, whereby the angular orientation of the plane of the tab section may be varied with respect to a Yaxis passing through the nozzle. The actuating-arm assembly includes a swizzle stick mounted on a transverse staff extending along an X-axis perpendicular to the Y-axis, the swizzle stick having a ball at one end thereof engaging the tab section of the flapper. The stick is caused to swivel on the staff about the Xaxis as a function of an applied error signal motion, and is also caused to shift along the X-axis as a function of a feedback signal motion whereby the position of the ball is the resultant of the error and feedback signals, and the degree to which it deflects the tab section of the flapper depends on the angle of this section with respect to the Y-axis.
