  • Patent number: 9885320
    Abstract: A pressure regulator (10) including a body (12) having an internal chamber (110) and a thermal shield (124) made of a material having a lower thermal conductivity than a material of the body (12) for reducing heat transfer between the body (12) and the fluid flowing into the internal chamber (110). By reducing heat transfer between the fluid and the body (12), the temperature of the components of the pressure regulator (10) is increased to reduce failure of the components and the density of the fluid is increased to improve the flow capacity of the pressure regulator (10).

  • Patent number: 8905057
    Abstract: A shunt pan is used to prevent excessive water damage from occurring if water leaking from a kitchen appliance is not discovered in a timely manner. The shunt pan directs the flow of collecting water into a walkway of a kitchen, where it is visible, rather than allowing the water to soak into surrounding kitchen walls and cabinets. A shunt pan is characterized by a rectangular floor bordered on three sides by walls, but not bordered by a physical obstruction on the fourth side, which is open. Preferably, the open side includes an indicator material, such as confetti or glitter in a water-soluble binder, that can be carried by flowing water into the walkway. If the water that carried the indicator material evaporates, the indicator material will remain in the walkway to clearly show the presence of a water leak.

  • Patent number: 8794595
    Abstract: Diaphragm valve with internal leak detection and improved external leak sealing performance. In diaphragm valves comprising diaphragms that have shields and backings, a rigid seal plate interposed between the shield and backing prevents peripheral regions of the shield from cold-flowing into the backing, despite the compression forces produced by tightening the fasteners that secure the diaphragm to the valve's bonnet assembly and body. An access port passing through the seal plate provides an interface between a void located between the shield and the backing and a breach detector. The breach detector is configured to detect pressure, volume, moisture or mass deviations in fluid disposed in the void, and the deviations indicate whether there's a rupture in the shield or the backing. The breach detector can be connected to an alarming device or signaling system to provide warnings and alerts to valve operators, process control panels or data communication networks.

  • Patent number: 8561453
    Abstract: A method and system for automatically calibrating all pressure sensors in a hydrogen storage system for a fuel cell vehicle. A pressure regulator in the hydrogen storage system, which has much greater accuracy at low pressures, is used to calibrate the high-range pressure sensors used in the hydrogen storage system. This calibration can only be done when the pressure regulator is in a fully open position. In such a condition, the pressure sensors can be calibrated to the regulation pressure value of the regulator, thus greatly improving the accuracy of the readings of the high-range sensors at the low end of their range. The calibration can be performed during fuel cell operation under certain circumstances, performed during a programmed shutdown sequence, or performed in a service procedure.

    Abstract: A duel fuel gas control valve controls the supply of gas (e.g., natural gas or liquid propane gas) to a gas grill. The duel fuel gas control valve is structured to control either natural or LP gas flow at the desired operating characteristics based on conventional gas supply characteristics and gas grill requirements. A restrictor mechanism, when in first and second configurations, respectively, restricts movement of the valve core to a first predetermined range for a first mode of operation (first type of gas supply) and to a second predetermined range for a second mode of operation (second type of gas supply).

  • Patent number: 8072343
    Abstract: A local logic solver that operates with a local smart valve controller to control, test and monitor performance characteristics of a local field-mounted emergency isolation valve device, outputting a local indication of trouble on the device, which is mounted in the field away from the facility's central control panel for the process. The local logic solver includes a recording function and memory for retrieval of detected faults that are time-stamped and recorded locally to generate documentation and to track the elapsed time, starting when the degraded state of the device was detected and first signaled as a problem; other performance data is also recorded. Accordingly, the operation of the overall system is simplified by eliminating the need for an external computer to diagnose any problems.

    Abstract: A process fluid flow system is provided having an input, an output, and a plurality of fluid circuits disposed between the input and output. At least one valve is disposed to selectably cause process fluid to flow through either a first circuit of the plurality of circuits, or a second circuit of the plurality of circuits. Process fluid flows through the first circuit during normal production, and through the second circuit during process fluid sequestration. A process fluid flow measurement device is operably interposed between the input and output and configured to measure total flow through the system. A separator is disposed in the second circuit and is arranged to allow the process fluid to separate gravitationally over time into immiscible components of the process fluid, the separator having a known internal volume. A guided wave radar level measurement device is preferably disposed to measure heights of interfaces within the separator.

  • Publication number: 20100313958
    Abstract: By monitoring pressure transients in a liquid within a liquid distribution system using only a single sensor, events such as the opening and closing of valves at specific fixtures are readily detected. The sensor, which can readily be coupled to a faucet bib, transmits an output signal to a computing device. Each such event can be identified by the device based by comparing characteristic features of the pressure transient waveform with previously observed characteristic features for events in the system. These characteristic features, which can include the varying pressure, derivative, and real Cepstrum of the pressure transient waveform, can be used to select a specific fixture where a valve open or close event has occurred. Flow to each fixture and leaks in the system can also be determined from the pressure transient signal. A second sensor disposed at a point disparate from the first sensor provides further event information.

  • Patent number: 7843354
    Abstract: A determination of bleed valve activation in a gas turbine engine can be difficult unless the engine is maintained at a steady idle state for comparison between that state and effects of activation of the bleed valve. Furthermore, specific test activation of bleed valves increases wear and tear on those valves. By sensing a flow pressure response signal and then through appropriate averaging and processing through a non-linear filter, it is possible to identify bleed valve activation by a target signal response exceeding a threshold indicative of such bleed valve activation.
