Abstract: A valve diaphragm processed by cold working a small concentric region of one surface has a permanent axisymmetric deformation. The deformed diaphragm can be used in a manner which causes continual elastic compression loading of the diaphragm material. The loading of the deformed diaphragm provides a valve restoring spring force and simultaneously defeats diaphragm tendency toward exhibiting hysteresis. The restoring force provided by the diaphragm can also lessen actuator hysteresis.

Abstract: For regulating engine exhaust and for environmental reasons, aircraft users are restricted from expelling engine fluids from engines onto airport ramps. All such fluid must be collected and subsequently burned or properly disposed of. The present invention installs witness drain valves in the drain lines between seal cavities and environmental collector tank. The witness drain valves have a small reservoir that will retain a known volume of fluid. As fluid passes from a leaking seal to the collector tank, a small sample is captured in the witness drain valve. Once the witness drain valve reservoir is full, the leaking fluid then flows on to a collector tank, which is also provided. During regular engine maintenance, technicians push on a spring loaded drain valve located on the witness drain valve reservoir. If fluid is detected, the seal is beginning to leak, and corrective maintenance may be scheduled while the leak rate is still within operational limits.

In one aspect of the invention, a control chamber with a sealable opening is formed about a drain hole in the filling chamber so that water must flow through the control chamber to reach the reservoir, and fluid access to the control chamber is controlled by a seal which engages the opening in the control chamber. Engagement of the seal with the opening in the control chamber is controlled by operation of a lid which covers the filling chamber. In another aspect of the invention, a flow rate control valve assembly is at least partially housed within the control chamber and has a portion which is proximate to the drain hole in the filling chamber connected to the reservoir, whereby a rate of flow from the filling chamber to the reservoir is selectively controllable by adjustment of the flow rate control valve.

Abstract: An SOI CMOS inverter circuit in which a silicide layer in combination with body tie regions tie a p-type body region and an n-type body region together. At the same time, however, the body regions remain floating electrically so that the benefits of SOI are maintained. The silicide layer permits excess carriers to be recombined via the respective body regions so that the body region potential does not get modulated by generation/recombination effects. Thus, a hysteresis effect in the inverter circuit will be reduced.

Abstract: The present invention relates to an anti-free-flow valve to prevent fluid free-flow through a tube assembly having a lumen. The valve device comprises a body disposed inside the lumen having a cylindrical portion formed adjacent a tapered portion, the cylindrical portion includes an opening and the tapered portion has a pair of beveled surfaces with ends that form a slit therebetween. The slit communicates with the opening through a passage formed through the body of the valve device. When the tube assembly is in a relaxed condition, the ends of the beveled surfaces confront one another and place the slit in the closed position which prevents fluid flow through the passage of the body and through the valve device.

Abstract: The present invention relates an anti-free flow valve for a fluid administration systems having a tube assembly with a lumen formed through therethrough coupled to a pump. The anti-free flow valve comprises a body including a cylindrical portion having an opening and a tapered portion which has opposing beveled surfaces with ends that form a slit bounded by side walls. The opening communicates with the slit through a passage formed through the body which is adapted to receive the tube assembly therethrough. Fluid free flow through the tube assembly is prevented by the slit being placed in the closed position when the ends of the opposing beveled surfaces are urged together when the tube assembly is in a relaxed condition. However, when a tensile force is applied along the tube assembly the inner diameter of the lumen decreases which urges the ends of the opposing beveled surfaces away from one another and places the slit in the open position, thereby permitting fluid flow through the body.

Abstract: A valve has a chamber (11) in a housing (10), in which the valve seat (17) is closed by a valve body (19). The valve seat (17) is supported by an actuator (15) which is capable of axially expanding and contracting. In response to an actuating signal the actuator (15) contracts which causes the valve seat (17) to move away from the valve body (19) so rapidly that the valve body (19) is not capable of following, which produces a flow passing through the valve seat (17). The flow pushes the valve body (19) back into the closed position. The valve allows short switching times and a high repetition rate to be achieved.

Abstract: A motor oil-filled protector device for use with an electric submergible pump motor, includes a tubular extension to inhibit contaminated fluid from contacting an internal pressure relief valve. A motor oil pressure relief valve within the protector has an intake in fluidic communication with at least one motor oil-filled expandable chamber and has a discharge in fluidic communication with a fluid-filled section of the housing. Over a period of time, wellbore fluids tend to leak into and displace motor oil within the fluid-filled section. A tubular extension is connected to the discharge of the pressure relief valve and extends into a lower portion of the fluid filled section. When motor oil is discharged from the pressure relief valve, such motor oil will tend to stay within the tubular extension, because the oil is lighter than the wellbore fluids, and thereby inhibit the wellbore fluids from contacting and possibly harming the operation of the pressure relief valve.

Abstract: This invention pertains to a method and apparatus for venting pressure from within a pressurized housing. It incorporates a sealing assembly that is secured within a housing and restrained against a pressurized channel by a nut. By loosening the nut, restraint on the sealing assembly is released thereby allowing fluid from the channel to travel the length of the sealing assembly and exit the housing. Conversely, by tightening the nut, restraint on the sealing assembly is reapplied which blocks the channel once again thereby preventing any more fluid from flowing.

Abstract: For use in a tilt action valve for dispensing a pressurized viscous product, in which a grommet is held by a mounting cup and secures the valve stem and body, product leakage between the grommet and valve stem is minimized by forming in the grommet a pocket which fills with the dispensed product and then lies tightly against the valve stem. The pocket causes the valve and grommet to be tilted with easier control. The pocket's operation simplifies the construction of the grommet and valve body, thus permitting dimensions which enable cheaper parts costs and assembly.

Abstract: A water jet aerator for use in a tub or spa having an eyeball-type nozzle which, when rotated, controls the flow of water through the aerator. The nozzle also can be swiveled to vary the direction of fluid flow into the tub. To prevent injuries due to falling, the nozzle is recessed so as not to protrude beyond the edge of a flanged bushing which clamps the aerator to the tub wall. The nozzle is easily manipulable despite being recessed since no sleeves for controlling fluid flow surround the nozzle. Also disclosed is an embodiment in which rotating the nozzle controls air flow so as to be a function of water flow. During ganged operation of aerators, this prevents the air inlet to the aerator from being open when the water inlet is not sufficiently open to prevent the backflow of water from the tub into the air inlet.
