摘要： An apparatus (10) for the location and removal of foreign objects from a difficult to access geometry utilizes a flexible lance (12) formed of individual hose bar segments (14) strung on cables (16) to give a structure that is flexible along its length and fairly rigid in a direction transverse to its length. Extending from working channels (18) of nozzle block (20) of the lance (12) are a pair of multi-prong retrievers (22). A miniaturized Videoprobe camera (24) is provided in the nozzle block (20) between the two retrievers (22). The retrievers are each connected to an actuating cable (26), which extends through the flexible lance (12) to a manual control (28). The camera (24) is connected by a cable (30) to suitable video processing circuits for generation of images on a video display (32). The cable (30) also houses a fiber optic bundle which conveys light to the area being serviced by the lance (12). The flexible lance (12 ) extends through a transporter (34), which positions the nozzle block end of the lance (12) opposite a portion of a steam generator or other difficult to access geometry. The transporter (34) moves along a transport rail (36) to move the nozzle block end of the lance (12) into position. The lance (12) is then advanced through the transporter (34) to move the nozzle block end into the difficult to access geometry and retracted to withdraw the nozzle block end from the difficult to access geometry.

摘要： The present invention provides a diaphragm valve including a housing having a chamber and an outlet opening within the chamber. A projecting valve seat, formed by a projection extending into the chamber, has a sloping, annular sealing surface surrounding the outlet opening. A valve body, preferably forming an armature of an electromagnetic coil, is also located within the chamber. The valve body has, at one end, a recess and a metal diaphragm covering the recess and chemically non-reactive with a flowing fluid passing through the chamber and out of the outlet opening. The valve body is adapted for movement towards and away from the valve seat between closed and open positions. In the closed position the diaphragm is flexed into the recess by the projection, conformingly and sealingly contacting the sealing surface and covering the outlet opening, to prevent the passage of flowing fluid. In the open position, the diaphragm is spaced from the valve seat and the outlet opening is uncovered to allow passage of the flowing fluid. The diaphragm is prestretched before attachment to the valve body so that the diaphragm conforms to the sloping sealing surface of the valve seat rather than creasing above the valve seat.
摘要翻译： 本发明提供了一种隔膜阀，其包括具有腔室和在腔室内的出口开口的壳体。 由延伸到室中的突起形成的突出阀座具有围绕出口的倾斜的环形密封表面。 优选地形成电磁线圈的电枢的阀体也位于腔室内。 阀体在一端具有覆盖凹部的凹部和金属隔膜，并与通过腔室的流动流体在出口开口之间化学地不起作用。 阀体适于在闭合位置和打开位置之间朝向和远离阀座运动。 在关闭位置，隔膜通过突出部弯曲进入凹槽，使密封表面顺应并密封地接触并覆盖出口，以防止流动的流体通过。 在打开位置，隔膜与阀座间隔开，并且出口开口未被覆盖以允许流动流体通过。 在连接到阀体之前，隔膜被预拉伸，使得隔膜符合阀座的倾斜密封表面，而不是在阀座上方压皱。

摘要： A vacuum controller for maintaining a defined vacuum pressure to a remote location, including a housing which defines a cavity. The controller includes means for connecting the cavity to the remote location, to a high vacuum, and to a control signal pressure. There is a cup-shaped plunger, having an opening in its side wall, which is adapted to reciprocate in the cavity, and there is a flexible diaphragm which seals between the housing and the plunger. The diaphragm also operates as a valving mechanism, such that, when the plunger moves in one direction, the diaphragm closes off the opening in the side wall of the plunger, and when the plunger moves in the other direction, it opens the opening. There is a check valve in said controller to prevent inversion of the diaphragms.

摘要： A switching valve for delivering fluids from different inlets to a pumping outlet utilizes a pressure responsive spool movable due to a pressure differential in the inlets to one position wherein one of the inlets feeds the outlet and a second position wherein the other of the inlets feeds the outlet. The spool carries a pair of umbrella valves for effectively controlling the flow of fluid to the outlets as well as a pair of biasing springs acting on each side of a piston diaphragm which has limited travel on the spool. An adjustable detent arrangement is provided on the end of the spool to keep the spool travel balanced and cooperates with the springs to furnish a snap acting valve.
