    • A file system (i) permits storage capacity to be added easily, (ii) can be expanded beyond a given unit, (iii) is easy to administer and manage, (iv) permits data sharing, and (v) is able to perform effectively with very large storage capacity and client loads. State information from a newly added unit is communicated (e.g., automatically and transparently) to central administration and management operations. Configuration and control information from such operations is communicated (e.g., automatically) back down to the newly added units, as well as existing units. In this way, a file system can span both local storage devices (like disk drives) and networked computational devices transparently to clients. Such state and configuration and control information can include globally managed segments as the building blocks of the file system, and a fixed mapping of globally unique file identifiers (e.g., Inode numbers) and/or ranges thereof, to such segments.
    • 文件系统(i)允许容易地添加存储容量,(ii)可以扩展到给定单元之外,(iii)易于管理和管理,(iv)允许数据共享,以及(v)能够执行 有效地具有非常大的存储容量和客户端负载。 来自新添加的单元的状态信息被传达(例如,自动和透明地)到中央管理和管理操作。 来自这些操作的配置和控制信息被传送(例如,自动地)回到新添加的单元以及现有单元。 以这种方式,文件系统可以跨越本地存储设备(如磁盘驱动器)和联网计算设备透明地覆盖客户端。 这种状态和配置和控制信息可以包括作为文件​​系统的构建块的全局管理的段,以及全球唯一的文件标识符(例如,Inode号)和/或其范围的固定映射到这些段。

    • Planing apparatus is disclosed having a rotatable cutting drum comprising a central, rotatable support, a plurality of secondary supports spaced around the central support and in parallel relationship thereto, and a plurality of apertured cutting members mounted on each secondary support and axially spaced apart. The spaces between the cutting members on one of the secondary supports is bridged or almost bridged when viewed in a direction normal to the axis of the drum by the cutting members on one or more of the other secondary supports. The drum is housed for rotation in a base structure having rear wheels and front wheels which can be displaced vertically to adjust the depth to which a surface, e.g. a road surface, is to be planed. The drum and wheels are driven by a motor supported on the base structure. Various different types of cutting members are disclosed.
    • 公开了一种具有可旋转切割滚筒的倾斜装置,该切割滚筒包括中心的可旋转的支撑件,围绕中心支撑件间隔开并与其平行的关系的多个辅助支承件,以及安装在每个辅助支承件上并且轴向隔开的多个有孔切割构件。 当其中一个辅助支撑件上的切割构件之间的空间由一个或多个其它辅助支撑件上的切割构件沿垂直于滚筒的轴线的方向观察时桥接或几乎桥接。 滚筒被容纳在具有后轮和前轮的基座结构中,该基座结构可以垂直移动以调节表面的深度,例如, 一条路面,是要刨平的。 鼓和轮由支撑在基座结构上的马达驱动。 公开了各种不同类型的切割构件。
