摘要： A magnetically actuated valve system for controlling fluid flow through a first conduit and a second conduit. A first sealing structure associated with the first conduit is moveable in response to a magnetic force to an open position and spring biased toward a closed position. The closed position prevents fluid flow through the first conduit. A second sealing structure associated with the second conduit is moveable in response to a magnetic force in a second direction, substantially opposite to the first direction, to an open position and biased toward a closed position. The closed position prevents fluid flow through the second conduit. A magnetic actuator assembly is constructed and arranged to actuate the first and second sealing assemblies substantially simultaneously by moving the first and second sealing structures in the first and second directions, respectively.

摘要： A pre-manufactured natural gas delivery station is presented to a client that filters, measures, controls, pre-heats, pressure reduces, odorizes, and provides communication, provides excess power, and provides excess heat for a host site. The design is pre-approved by supply pipeline, end users and regulatory bodies. The final configuration is welded, assembled, wired, painted, tagged, and tested, at a factory site and then shipped to an installation site in accordance with customer's requirements. The station is commissioned, operators are trained and a three volume project DATA book is installed in the control room for documentation. The pre-manufactured natural gas delivery station can include a high pressure gas metering room and regulating room that can be selectively coupled to other prefabricated modular rooms or modules. Preferably, the other prefabricated modules include an odorant room, a heating room, an energy generation room and an electrical control and communications room. The equipment and control systems for each room is preinstalled and secured to the building structure in each of the different modules at the factory site. The energy generation room and the electrical control room allows the gas metering station to be operated by electrical energy from a local utility line or from an internal generator that is fueled by the gas being metered.

摘要： A reliable and economical apparatus for relieving pressure in a large aircraft cabin oxygen supply, where multiple oxygen cylinders are used concurrently. A series-parallel array of valves actuated by changes in differential pressure between the oxygen supply and the ambient cabin atmosphere provides overpressure relief The series connection of the valves reduces the risk of open-valve failures, while the parallel connection of sets of series-connected valves reduces the risk of closed-valve failures. The small number of valves used in its design reduces the cost of the apparatus. The series-parallel structure is optionally extended to larger numbers of valves to facilitate the use of less-expensive valves and supporting components without loss of reliability.

摘要： A method and an apparatus, the apparatus including appropriate valves and conduits, for increasing throughput in pressurized fluid processing including storing in a storage chamber of the apparatus a quantity of fluid at a pressure higher than a pressure at which an operation is to take place, while a processing chamber is depressurized to allow reception of a new object; sealing the processing chamber; and allowing fluid stored in the storage chamber to pass to the processing chamber to re-pressurize the processing chamber before performing the operation. The fluid may be preheated in the storage chamber to further reduce processing times.

摘要： A gas recirculation flow control method and apparatus for use in an evacuation system having a vacuum chamber into which a gas is introduced, a first vacuum pump for exhausting the gas from the vacuum chamber and reducing the pressure in the vacuum chamber to a desired pressure, a second vacuum pump for performing evacuation to lower the back pressure of the first vacuum pump below an allowable back pressure, and a gas recirculation line for returning a part of gas exhausted from the first vacuum pump to the vacuum chamber. The recirculation flow rate Q2 of the gas returning to the vacuum chamber through the gas recirculation line is controlled by adjusting the differential pressure Pd−Pc in the gas recirculation line by varying the effective pumping speed of the second vacuum pump using the following relationship: Q2=C×(Pd−Pc) where: Q2 denotes the recirculation flow rate of the gas returning to the vacuum chamber through the gas recirculation line; Pc denotes the pressure in the vacuum chamber; Pd denotes the pressure in the upstream side of the gas recirculation line; and C denotes the conductance of the gas recirculation line.

摘要： A system and method for integrating gas components that combines together, either in an in-line or modular fashion, at least two gas components used in a gas stick for flowing a gas from a first point to an end point. In one embodiment, the present invention can be used to combine a pressure transducer, a filter, and a display into a single unit that will reduce the gas stick size along the gas flow axis of the gas stick. The gas components can be integrated using VCR connections for an in-line use of the present invention. In the modular form, the present invention can use a number of different connections to connect the gas components vertically on a modular base block (i.e., stacked approximately perpendicular to the modular base block). Thus, the gas components will stack vertically with respect to the traditional horizontal gas flow path axis.
