    摘要： A roller cone drill bit is disclosed which includes a bit body adapted to be coupled to a drill string. A bearing journal depends from the bit body. A single roller cone is rotatably attached to the bearing journal. The roller cone has a plurality of inserts disposed at selected positions about the cone. The journal defines a rotation angle with respect to an axis of rotation of the bit such that the roller cone includes a wall contact zone and a bottom contact zone. At least one of the inserts disposed in the wall contact zone has an extension portion terminating in a substantially planar upper surface.

    摘要： An infrastructure that allows applications to run with specified versions of dependent assemblies, wherein each assembly may exist and run side-by-side on the system with other versions of the same assembly being used by other applications. An application provides a manifest to specify any desired assembly versions on which it is dependent. Similarly, each assembly may have an assembly manifest that specifies the versions of assemblies on which it is dependent. During an initialization phase, an activation context is created for the application, based on the manifests, to map version independent names to a particular assembly version maintained on the system. While the application is in a running phase, for any globally named object that the application wants created, the activation context is accessed to locate the application's or assembly's manifest-specified version. The manifests and activation context constructed therefrom thus isolate an application from assembly version changes.

    摘要翻译： 允许应用程序使用指定版本的依赖程序集运行的基础架构，其中每个程序集可能存在并且并行运行在系统上，而其他应用程序正在使用同一程序集的其他版本。 应用程序提供了一个清单，用于指定所依赖的任何所需的程序集版本。 类似地，每个程序集可能具有一个程序集清单，它指定它所依赖的程序集的版本。 在初始化阶段期间，基于清单为应用程序创建激活上下文，以将独立于版本的名称映射到系统上维护的特定程序集版本。 当应用程序处于运行阶段时，对于应用程序想要创建的任何全局命名对象，访问激活上下文以查找应用程序或程序集的清单指定版本。 因此，由此构建的清单和激活上下文将应用程序与组装版本更改隔离。
