摘要： A regulator valve having a globe type valve body includes a deformable diaphragm for controlling the fluid flow between the a fluid inlet and a fluid outlet. The deformation of the diaphragm, which is controlled by a pilot pressure introduced into a control chamber within the valve, causes the diaphragm to selectively covers and uncovers a plurality of apertures in a frustoconical baffle to control the flow through the valve. The valve includes a first diaphragm support provided in the control chamber and a second diaphragm support provided on the opposite side of the diaphragm. The second diaphragm support comprises a plurality of concentric cylinders and cross members which form an upper concave surface to correspond to a convex portion of the diaphragm so that the diaphragm is substantially uniformly supported.

摘要： This invention provides an ultrasonic transducer probe for medical scanning and a lens assembly for use therein. The probe has a housing in which an ultrasonic transducer array is mounted, there being an opening in the housing adjacent the transducer array. A first lens subassembly is mounted to the transducer and moves therewith if the transducer is rotated. A second lens subassembly is mounted to the housing to fill the opening therein, and includes, for example, a thin plastic film covering the opening and bonded to the housing to seal the opening and a film backing lens or layer. The first lens subassembly is preferably a compound lens. The lens subassemblies are formed of materials having relative acoustic properties, and having mating surfaces which are shaped, to selectively focus ultrasonic signals from the transducers.

摘要： An extremely accurate and reliable fluid pressure sensor for monitoring process pressure and sensing when predetermined pressure set points or limits have been reached. A Bourdon tube with a pivotally moving lever end responds to the process pressure. When the process pressure is within the desired pressure range, a fluid operated block and bleed relay is operated to provide a first pressure level at its outlet. As the preset pressure point is reached, the relay is operated to provide a change in the outlet pressure level for actuating suitable safety units. A pivoting beam responds to pivoting movement of the Bourdon tube lever arm about the pressure set points and effectively amplifiers or increases such movement to rapidly operate the relay. Snap-acting cap means with a self-aligning disc cap a nozzle port in the relay in response to pivoting beam movement.

摘要： A pilot-operated back pressure regulator of simplified design and construction having a balanced valve plug attached to a diaphragm actuator and secured to the regulator body by bolts for ready simultaneous removal of the plug and actuator. The diaphragm divides the actuator into two cavities; a spring cavity acting to close the valve plug and pressure balancing cavity. A pilot valve is in communication with the inlet pressure to the regulator body, the spring cavity and an exhaust to regulate the inlet pressure to flex the diaphragm. In a preferred embodiment O-ring seals are located between (a) the valve plug and the valve seat, (b) the valve plug and its guide, and (c) the valve plug guide and the regulator body.

摘要： An in-line gas flow rate sensor includes a movable flow orifice and a fixed flow restrictor adjacent the flow orifice for changing the gas flow through the flow orifice. The flow orifice and the flow restrictor are formed so that each uniform increment of flow orifice movement provides a constant percent of flow change through the flow orifice. A magnet fixed to the movable flow orifice provides changing magnetic flux corresponding to each uniform increment of flow restrictor movement. A magnetic flux sensor responds to the changing magnetic flux and provides an output corresponding to a constant percent of flow rate changes.

摘要： A pressure relief diaphragm type regulator valve includes a velocity boost body having an annular-shaped wrap-around pitot tube communicating with the vena contracta of a flowpath. The pressure at the vena contracta is communicated to the diaphragm by a small registration orifice in the boost body. The boost body defines a large relief orifice open to the annular pitot tube, but normally closed off from the diaphragm by a flapper. Under a rapid excess pressure condition, the flapper uncovers the relief orifice and large volume flow is permitted to the diaphragm.

摘要： A rolling diaphragm regulator valve is affixed in a globe type valve body and includes a non-stretchable fabric reinforced liner for covering and uncovering, by rolling action in response to changes in pressure in a control chamber, a plurality of slots in a baffle positioned between the valve body inlet and outlet. An axially movable spring-biased nose cone, mounted behind the diaphragm, provides a surface over which the diaphragm is draped for controlling substantially all movement of the diaphragm. A travel indicator is operable by movement of the nose cone to provide a visual indication of the position of the valve.
