    摘要： A shaft sealing system and method are disclosed for a high or intermediate pressure turbine section having a rotating member including a shaft and a stationary member surrounding the rotating member and defining a steam flow path. The shaft sealing system comprises at least one seal disposed about each of a first end and a second end of the shaft; and a connection line for conducting steam from the first turbine section to a downstream portion of the turbine. The downstream portion of the turbine is one of a low pressure section and a condenser, and has a lower pressure than both of the first turbine section and ambient pressure conditions.

    摘要： A system and method is described which provides for context checking of an operating environment. A context manager controls the execution of context checks requested by applications or processes. In one embodiment, the context check modules are defined as self-contained modules located in a database. When the data base is opened, these modules are loaded and registered with the context manager. Upon occurrence of certain user actions, the context manager will issue an event to cause the appropriate modules to perform a context check of certain context of the environment. The resulting context information is stored in memory by the context manager and provided to the applications by the context manager when needed. One advantage is that the context checks performed can be changed simply by adding or deleting modules from the database. In other embodiments, context checking functions can also be provided by providing context files, which are loaded at initiation of the context manager and are independent of the database utilized, and by providing certain highly repeatable functions within the function of the context manager itself.

    摘要翻译： 描述了提供对操作环境的上下文检查的系统和方法。 上下文管理器控制应用程序或进程请求的上下文检查的执行。 在一个实施例中，上下文检查模块被定义为位于数据库中的自包含模块。 当数据库打开时，这些模块被加载并注册到上下文管理器。 在发生某些用户动作时，上下文管理器将发出一个事件以使适当的模块执行环境某些上下文的上下文检查。 所得到的上下文信息由上下文管理器存储在存储器中，并且在需要时由上下文管理器提供给应用。 一个优点是可以简单地通过从数据库中添加或删除模块来更改执行的上下文检查。 在其他实施例中，还可以通过提供上下文文件来提供上下文检查功能，所述上下文文件在上下文管理器的启动时加载并且独立于所使用的数据库，并且通过在上下文管理器本身的功能内提供某些高度可重复的功能。

    摘要： A user interface includes an object oriented graphic user interface having overlapping windows and provides an access window having topics, index and look for button functions for selection by a user. Through the use of the topics, index or look for functions, a help inquiry is defined. The access window includes an alpha scroll bar horizontally spanning a defined area of the access window. A plurality of alpha-numeric, symbolic or other characters (collectively "characters") are displayed along the length of the alpha scroll bar. A slider is provided which may be selectively positioned over a character displayed on the alpha scroll bar. The slider may be positioned through user manipulation of a cursor control device. The placement of the slider over a character on the alpha scroll bar results in a central processing unit (CPU) displaying data corresponding to the character selected. Entries are displayed in the defined area beginning alphabetically with the letter over which the slider has been placed.

    摘要： The system includes at least one central processing unit (CPU) which is coupled through appropriate input/output (I/O) circuitry to input devices, such as a keyboard, digital pad, mouse and/or track ball. The CPU is coupled to a hard disk drive for the storage of programs and data, and may also be coupled to a network through which the CPU may communicate with a variety of other system resources and devices. The CPU is further coupled to a display device such as a CRT or liquid crystal display, on which the present invention is displayed. The user interface of the present invention includes an object oriented graphic user interface having overlapping windows. The present invention includes an access window having topics, index and look for button functions for selection by a user. Through the use of the topics, index or look for functions, a help inquiry is defined. The selection of one of the button functions results in the CPU generating and displaying entries in a predefined area of the access window. Upon the selection of one of the entries by a user, the CPU displays phrases related to the selected entry in a working area of the access window. The selection of one of the phrases results in the CPU displaying a presentation window on the display, which includes help instruction data to guide the user in the particular help task specified by the entry and phrase selection.
