摘要： A recess is provided at the periphery of the flapper so that a corner that defines this recess engages an o-ring seal in a seat for the flapper. A reduced contact area of the flapper on the o-ring seal results in increased pressure over the actual contact area. The pressure applied over the contact area also forces a distortion in the o-ring that has a part of the o-ring not restrained due to the presence of the recess moving out of the surrounding o-ring groove so that the corner on the flapper pinches the o-ring that now is partly in and partly extending from its surrounding groove. Sealing is obtained at lower differential pressures and the o-ring is better fixated as a result of the pinch effect of the corner on the flapper.

摘要： The method and apparatus of the present invention includes a method for providing a non-container object with the appearance of container object attributes in a graphic user interface operating environment. This method and apparatus includes creating a container manager and associating the container manager with the non-container object. A container pane is created and associated with the container manager. This container pane is in communication with the container manager and a list control in the graphic user interface operating environment. The container pane in the container manager both interact to provide the non-container object with the appearance of the container object attributes. If an item is present in the non-container object when the non-container object is started, a contained object is created for the item to be displayed within the non-container object. Next, if an item is added to the non-container object, a contained object is created for the item to be displayed within the non-container object. When an item is removed from the non-container object, the contained object for the item is deleted. When a contained object is present, the container manager is provided control over the display manipulation of the contained object while that contained object is within the non-container object. Moreover, the container pane graphically displays an icon that represents the contained object in a window. The container pane also relays input by a user to the container manager.

摘要： A control system for a Subsurface Safety Valve (SSSV), includes an actuating piston mounted in a housing with at least one seal and connected to the SSSV. The actuating piston having a first end and a second end, the first end in fluid communication with a control line; a primary pressure reservoir in fluid communication with the second end of the actuating piston, the reservoir configured to contain a fluid under an amount of pressure selected to act against a prospective hydrostatic pressure expected in the control line based upon the selected position of the control system in a downhole environment. An equalizing piston in fluid communication with both the control line and with the second end of the actuating piston, the equalizing piston remaining in a closed position during shifting of the actuating piston with pressure applied or removed from the control line, the equalizing piston movable to an open position upon a control system failure that reduces pressure in the primary reservoir to below a threshold value; and a condition sensing and chemical injection assembly in fluid communication with the primary reservoir. A method for operating a control system for a Subsurface Safety Valve (SSSV).

摘要： An interface for a neural network includes a generalized data translator and a certainty filter in the data path including the neural network for rendering a decision on raw data, possibly from a data processing application. The data translator is controlled with user-definable parameters and procedures contained in a property list in order to manipulate translation, truncation, mapping (including weighting) and other transformations of the raw data. The neuron to which the output of the data translator is applied is controlled by a code index contained in an action list. An external certainty threshold is also provided, preferably by the action list to filter the output of the neural network. The core program used with the ConExNS neurons for system maintenance also includes further core operations and size maintenance operations responsive to commands from the user of an application to cause operations to be performed with in the neural network as well as to create and update the property and action lists.
