摘要： A safety element is disclosed for influencing or inspecting fluid media in a duct, in particular a double-walled safety duct whose walls are separated by a hollow space. The safety element has a housing formed by walls and flanges for sealingly connecting it to the duct. The housing is surrounded on all sides by a second wall (6) separated from the first wall (5) by a hollow space (7) which is closed in a gas-tight manner and can be connected with measurement equipment for inspecting its contents. The hollow space (7) communicates through one or several bores (13) with a groove (15) shaped around the duct into the sealing surface (14) of the flange (1) or its seal (18).

摘要： A flow-control valve has an outer housing assembly including an outer housing member, a tube fixed to the member and having an inner end remote from the member, and an end collar of high-alloy steel welded on the tube end. An inner housing member is formed of nonferrous metal with an inlet port and an outlet port and a valve seat between the ports. The end collar is seated in the inner housing member and a valve stem has an outer end at the outer housing member and an inner end projecting into the inner housing member and guided in the end collar, extending through the tube between the members, and carrying a valve body sealingly engageable with the seat. A connecting sleeve engaged around and fitted snugly to the end collar and inner member has an outer ring of high-alloy steel welded to the end collar and an inner ring of nonferrous metal, fixed integrally to the outer ring, and welded to the inner member.

摘要： A drain valve removes liquid from a compressed air system whenever cycling pressure of the system reaches either a preselected high drain pressure or a preselected low drain pressure at an inlet port of the valve. An inlet face of a piston of an adjustable pressure valve assembly within a valve body normally seals the inlet port when there is no pressure. The piston is located within a portion of a central cavity of the valve. The piston's inlet face is of a size which allows the force of the adjustable pressure valve assembly to be overcome by a pre-selected high drain pressure at the inlet port. The area of a vent face on the other side of the piston has a size which, when the vent face is sealing the vent passageway, prevents the force exerted by the adjustable pressure valve assembly from overcoming the pressure of the compressed air system until a pre-selected low drain pressure is reached at the inlet port. In either case, the relative sizes of an opening between an inlet cavity and a vent cavity within which the piston is mounted and a vent orifice, and the area of a dividing member mounted across the piston between the inlet cavity and the vent cavity, allow liquid to be drained by the drain valve until such time as all liquid has been removed and compressed air fills the valve.

摘要： Apparatus, positioned at an inlet port to a pump, for shielding the pump from a process chamber of a semiconductor wafer processing system, where the apparatus has a controllably variable effective throughput area, and method for electrically controlling the size of the effective throughput area. Specifically, the apparatus is a controllable restrictor shield supported by an actuator, having a first effective throughput area and a second effective throughput area, where the first effective throughput area is typically less than the second effective throughput area. The size of the effective throughput area is directly responsive to an electric signal that controls the actuator.

摘要： An internal valve for pressurized fluid containment vessels having vessel ports. The valve includes a valve seat associated with the vessel port and a valve member movable between a closed position against the valve seat and an open position wherein fluid can flow through the vessel port. A control chamber positioned in the vessel is connected to the valve member. A motive mechanism acting on or in the control chamber, by a control system outside of the vessel, controllably moves the valve member to at least one of the open or closed positions. The control chamber is sealed from fluid in the vessel by a sealing system, which includes a flexing surface against which fluid pressure in the vessel acts to thereby bias the valve member towards one of the open or closed positions.
