摘要： A tool magazine for an automatic machine producing various machining operations with the aid of machine tools held by a machine spindle. The magazine for replaceable tool is adapted to hold a plurality of tools each in tool holding mechanisms being held on a tool pallet mounted on a rotary table of the automatic machine. The spindle cooperates with the magazine so as to be in alignment with a tool holding mechanism of the magazine at a tool replacement position; whereby a new tool can be withdrawn from the tool holding mechanisms by the spindle or a used tool held by the spindle can be inserted into the tool holding mechanism. In addition, the magazine is indexed, to align the several tool holding mechanisms, one at a time, with the spindle at the tool replacement position by transmitting spindle movement, preferably through a tool, to the magazine. The magazine may include a plurality of magazine units, each carrying several tool holding mechanisms on a supporter adapted for rotation about a shaft in response to defined spindle movement. Releasable lock mechanisms prevent non-commanded support rotation.

摘要翻译：一种用于自动机器的刀库，借助于机床所保持的机床，生产各种加工操作。用于可更换工具的盒子适于保持多个工具，每个工具保持在安装在自动机器的旋转台上的工具托盘上的工具保持机构中。主轴与刀库配合，以便在工具更换位置与刀库的刀具保持机构对准; 从而可以通过主轴从工具保持机构中取出新的工具，或者由主轴保持的使用的工具可以插入到工具保持机构中。另外，通过将主轴运动（优选地通过工具）传送到料盒，使刀库被分度，以便将多个刀具保持机构（一次一个）与主轴对准刀具更换位置。杂志可以包括多个杂志单元，每个杂志单元在支架上承载几个工具保持机构，其适于响应于所确定的主轴移动而围绕轴旋转。可释放的锁定机制可防止未命令的支持旋转。

摘要： To facilitate protected distribution of digital data files, the files are segmented, and each segment (e.g. disk sector) is encrypted separately. Some segments can be left unencrypted, speeding access since less decryption is required. Different segments can utilize different encryption techniques, increasing protection against unauthorized decryption. A table stored in association with the encrypted data provides authorized users with data identifying the encrypted segments, and the form of encryption used. Decryption is accomplished with a layered set of operating system software that operates in conjunction with said table. Specialized APIs aren't used; applications programs are provided with unencrypted data using conventional APIs. Internal interfaces, invisible to the APIS, intercept normal processing calls (e.g READs) and direct them to internal decryption software that returns decrypted data back to the APIs.
摘要翻译：为了方便数字数据文件的保护分发，文件被分割，并且每个段（例如磁盘扇区）被单独加密。一些段可以保持不加密，加速访问，因为需要较少的解密。不同的段可以利用不同的加密技术，增加对未经授权的解密的保护。与加密数据相关联地存储的表格为授权用户提供标识加密段的数据以及所使用的加密形式。解密是通过与所述表一起操作的分层操作系统软件来实现的。不使用专用API; 应用程序使用常规API提供未加密的数据。 APIS不可见的内部接口拦截正常的处理调用（例如READ），并将它们引导到将解密后的数据返回给API的内部解密软件。
