Abstract: Drilling mud is lifted subsea to a drilling vessel with a mud pump having an internal bladder. Applying pressurized water to one side of the bladder urges it against a quantity of the mud to impart a lifting force onto the mud. Mud flow to and from the pump is controlled by valves driven by actuators. The actuators include a piston in a cylinder, a stem that connects the piston to a valve member, and ports for supplying fluid to opposing ends of the piston for selectively reciprocating the piston. Cavities are strategically location in the cylinder for absorbing vibrational forces generated when the piston reaches an end of its stroke.

Abstract: A method and system for lifting drilling mud from subsea to a drilling vessel includes a pump having a body with a chamber, and a bladder in the chamber. The bladder spans the chamber to define water and mud sides in the chamber. A mud inlet valve allows mud into the mud side of the chamber; which moves the bladder into the water side and urges water from the water side of the chamber through a water exit valve. Pressurized water enters the chamber through a water inlet valve, which in turn pushes the bladder and mud from the chamber through a mud exit valve. The bladder separates the mud and water as it reciprocates in the chamber. A pressure control circuit equalizes pressure across the water valves, and a control valve provides a back pressure in a discharge of the pressure control circuit.

Abstract: In a web application, a user computer that executes a browser presents a help window on a monitor associated with the user computer, simultaneously with displaying portions of a web page obtained by the browser from a server, to enable a user of the user computer to view the help information without interfering with the user's interaction with the web page. The displayed help information pertains not to the browser itself, but to the web page.

Abstract: A computer system and method provides access to a software application from a web browser over the world-wide web (WWW). The system includes one or more computers executing a web browser, a web server application, an application gateway, and a software application. The system and method allows a user of the web browser to access the software application. The user inputs data via the web browser, which is communicated to the web server application. The web server application authenticates the web browser and passes appropriate input data to an application gateway, including data to uniquely identify and track the user's request. The application gateway then performs the function requested in the web server input data by formatting the appropriate commands with the software application. The software application responds by outputting data to the application gateway that includes an identifier that the application gateway uses to match the output data with the web browser that requested the output data.

A browser window is partitioned into frames. The browser window frames include a parent frame. A plurality of variables are created in the parent frame. Each of the plurality of variables defines an MRI string. Then the variables are used in the browser program function codes for displaying MRI.

Abstract: An enhanced document browsing method and apparatus. A browser at a client interprets a work-frame code, information, a control-frame code, and a control-object function that identifies the control-frame code. When the browser interprets the work-frame and control-frame codes, it divides the browser window into two frames: a work-frame and a control-frame. When the browser interprets the information, the browser displays the information to the user in the work-frame. When the browser interprets the control-object function, the browser displays a control-object in the control-frame associated with the control-frame code. The control-object can allow the user to control the information in the work-frame. Since the control-object is in the control-frame instead of being only in the work-frame, it is always in view and available to the user, regardless of the scrolling position of the page of information within the work-frame.

Abstract: An enhanced document browsing method and apparatus for requesting transactions of transient programs at a server, that sends a first transaction to a server that requests first data from a first transient program; receives the first data from the server; inserts the first data into an entry field; and requests a second transaction from a second transient program by sending the first data to the server.

Abstract: The present invention provides a system and method of performing user authentication on web based applications, such as IBM's Network Station Configuration Preference Manager. In particular, the system and method saves and continuously passes user information back and forth between a web client and a web server. The user information can then be used by CGI programs being executed on the web server for authentication purposes. Specifically, each CGI program will examine the user information, determine the authority privileges of the user, run the CGI program under a non-default user mode, return user information back to the web client, and return the CGI job to run in a default user mode.

Abstract: The present invention provides the capability to easily access many different application programs over the WWW via a common user interface. By providing standard procedures, routines, tools, and software "hooks" for accessing software applications over the WWW, software developers can concentrate on the functionality of the application program and easily use HTML to provide a GUI interface for the application program. HTML is a well-known language which can be used by almost any computer system on the market today. In addition, since HTML is a fairly well controlled and standardized language, new software application features can be added as they are developed and supported by HTML. In addition, since HTML is a widely adopted, non-proprietary technology, the present invention can provide open access to a large market for even very small software developers.

Abstract: The present invention provides a system and method of workstation configuration that includes a multi-level hierarchy management of preferences which are essentially managed and stored with a file server, rather than with each individual workstation. The invention comprises a computer network that includes workstations that have configurable hardware devices and software applications; a workstation server connected to the workstations that includes hierarchical preference files containing configuration information; and a preference manager for providing a coalesced, or merged, set of configuration parameters to the workstations based on the information in the hierarchical preference files.

Abstract: A method and system are disclosed which permit the presentation of single and double digit selection field in a non-programmable terminal. Multiple numeric characters associated with particular textual choices are coupled to a workstation controller interface along with an identified offset within each textual choice to a selected mnemonic character. If an associated terminal display device does not support more advanced graphic elements, such as so-called "radio buttons" and underscored mnemonics, the numeric characters and textual choices are entered into a format table entry and utilized to specify a selection field within the terminal display. A single or double digit numeric indicator area is then defined within the terminal display and numeric entries within the selection field are displayed within the numeric indicator area, permitting the user to visually affirm what textual choice will be selected upon entry.
