Abstract: A method for audibly detecting a fluid flow state change in a flow meter pipeline. The flow state change may be identified as an upset in the normal flow state. The upset may be corrected to improve the accuracy of the flow meter. A system includes acoustic sensors mounted in the flow meter pipeline, and a computer to collect audible data from the acoustic sensors and compare the audible data to a baseline to detect an upset in the normal fluid flow state.

Abstract: Apparatus and methods for proving a flow meter at low temperatures. A flow meter measuring low temperature fluids (e.g., less than about ?50° F., or less than about ?220° F.) must still be proved. Low temperature fluids can be destructive to piston or compact provers, or may require indirect proving methods. The apparatus disclosed is a low temperature prover directly coupled into the pipeline carrying the low temperature fluids. In some embodiments, a magnetic pickup coil and a magnetic member communicate between the displacer and the flow tube. The magnetic target member may be carbon-free. In some embodiments, a pair of ultrasonic transceivers coupled to the flow tube communicate a signal across the flow tube and a displacer is moveable to interrupt the signal. In some embodiments, the flow tube includes an inner surface having a microfinish for lubrication. The displacer may be a piston rotatable while being moved axially.

Abstract: A system for maintaining pressure in the liquid fuel tank of a high-speed flight vehicle, such as a hypersonic flight, scramjet powered air and space vehicle, manages tank ullage using a pressure regulator coupled to the fuel tank that supplies pressurized gaseous media into the fuel tank ullage based on the internal pressure of the tank. The regulator has an on-board controller that processes tank pressure input to deliver a pulse-width modulated input signal to the coil of the on-board solenoid metering assembly. Energizing the coil drives the metering valve open against spring force. The metering assembly is contained in a removable cartridge that has a floating valve guide that is held stationary by bias of the spring against the metering valve. The metering valve has a separate valve seat that mates with the metering orifice of a flow nozzle.

Abstract: A security system and method of monitoring a portable device. The security system has a first sensor, a controller, and an alarm signal generator. The controller is capable of detecting that the first sensor, with the security system in an armed state, has changed from the secured state, and as an incident thereof, causing a signal to be generated by the alarm signal generator. The controller and first sensor are configured so that under certain conditions the first sensor must be changed from the unsecured state into the secured state and maintained in the secured state for a predetermined time period before the controller, first sensor and alarm signal generator can thereafter interact to produce a detectable signal in the event of a security breach.

Abstract: Apparatus is provided for use with a subject's body, vagina, vaginal fornix, uterus, and uterine artery. A fornix-engaging structure is inserted into the vagina and engages the vaginal fornix. A rod is inserted into the subject's body via the fornix-engaging structure, such that a distal end of the rod passes through vaginal tissue at a first vaginal site until the distal end of the rod is at a first extrauterine site outside of the uterine artery, but in a vicinity of a portion of the uterine artery that supplies a uterine fibroid. A rod-guide is coupled to the fornix-engaging structure, and guides the distal end of the rod to the first extrauterine site. A uterine artery compression device is disposed on the distal end of the rod. Other embodiments are also described.

Abstract: A multi-channel, multi-phase flow metering valve has multiple pintle valves for metering liquid media through each valve channel. The valve channels have venturi passageways that alone, or in cooperation with the pintles, cause the local pressure of the media to fall below its saturated vapor pressure and allow the liquid media to change phase. The cavitation creates a gaseous region, formed from one or many discrete cavities, in the media within valve channels that effectively isolates the pressures in the upstream and downstream parts of the valve channels to reduce the affects of input pressure fluctuations in the output media. The valve components, particularly the modules defining the venturi passageways, are made of a high-strength material to better resist pitting and other surface erosion from sonic shock associated with the collapse of the gaseous cavities.

Abstract: A water cooled valve is provided in the form of a check valve, an air purge valve, a distributor valve, a combination air purge and distributor valve and the like for use in the liquid fuel system of a gas turbine. A movable valve member controls the flow of fluid through the valve's fuel circuit. A separate cooling circuit circulates cooling water through the valve near or alongside the valve member. The water is of a lower temperature than the high temperature liquid fuel, and thereby carries away heat transferred to the valve by the fuel. In one form, the cooling circuit is formed in part by a helical groove in the periphery the valve body housing the valve member. A sealed water jacket surrounds the valve body and has dedicated supply and return ports for coupling the valve to a water supply via water lines. The water ports are positioned tangentially to induce swirling flow inside the valve.
