摘要： An operating system which is particularly adapted to heterogenous distributed systems. Entities available to a process running in the operating system are provided by services. Each service models its entity as a set of files. The entity is controlled by performing operations on the set of files provided by the entity. Services other than those provided by the operating system all employ the same protocol specifying operations on files. The only requirement placed on a service by the operating system is that it be able to accept and respond to messages employing the protocol. The files are named, and the operating system provides a plurality of name spaces, relates each process to one of the name spaces, and permits any process to modify its name space or to create a new name space. Services are disclosed which provide each process using the service with its own set of the service's files and which provide files belonging to one process's namespace to another process executing on a different processor.
摘要翻译：特别适用于异构分布式系统的操作系统。在操作系统中运行的进程可用的实体由服务提供。每个服务将其实体建模为一组文件。通过对实体提供的文件集执行操作来控制实体。除了操作系统提供的服务之外的服务都采用指定文件操作的相同协议。操作系统对服务的唯一要求是能够接受和响应采用协议的消息。这些文件被命名，并且操作系统提供了多个名称空间，将每个进程与名称空间相关联，并允许任何进程修改其名称空间或创建新的名称空间。这些服务被公开，其使用服务具有其自己的一组服务文件并且将属于一个进程的命名空间的文件提供给在不同处理器上执行的另一进程的每个进程。

摘要： A file system which has component file systems including a primary file system which is react/write and a number of dump file systems which are read only. Each dump file system is created from the primary file system by means of a dump operation and conserves the state of the primary file system at the time the dump operation was performed. Component file systems share read only storage elements with older component file systems. The file system is implemented on a system including a file server, a magnetic disk mass storage device, and an optical write once-read many (WORM) disk. The magnetic disk mass storage device contains the read/write storage elements of the primary file system and encached read only storage elements from the WORM disk. Space is reserved on the unwritten portion of the WORM disk for the read-write storage elements of the primary file system. Techniques for performing file operations including opening, reading, writing, creating, and deleting files are disclosed, as well as techniques for performing the operations of dumping and restoring the primary file system.
摘要翻译：具有组件文件系统的文件系统，包括反应/写入的主文件系统以及只读的多个转储文件系统。通过转储操作从主文件系统创建每个转储文件系统，并在执行转储操作时节省主文件系统的状态。组件文件系统与旧组件文件系统共享只读存储元素。文件系统在包括文件服务器，磁盘大容量存储设备和光写入一次读取（WORM）光盘的系统上实现。磁盘大容量存储设备包含主文件系统的读/写存储元件和来自WORM磁盘的仅读存储元件。在主文件系统的读写存储元素的WORM磁盘的未写入部分保留空格。公开了用于执行包括打开，读取，写入，创建和删除文件的文件操作的技术，以及用于执行转储和恢复主文件系统的操作的技术。

摘要： A protective helmet having thick padding adhesively attached to its inner periphery so as to completely engage the wearers head -- forehead, temples, sides and back thereof including the neck -- and being thick enough to enclose and cushion a radio, battery and earphone and still provide adequate cushioning protection, and to the lining per se.
摘要翻译：一种保护性头盔，其具有粘附在其内周上的厚填充物，以便完全接合包括颈部在内的穿着者头部 - 前额，其后部和肩部 - 并且足够厚以封闭和缓冲收音机，电池和耳机并仍然提供足够的缓冲保护，以及衬里本身。
