    • A system, apparatus and method for updating security configurations of a plurality of servers from a centralized directory server. The system includes a centralized directory server and a plurality of servers that provide resources and store files for use by users of the system. Each file/resource associated with the servers includes a security parameter list identifying authorized users of the file/resource. The security parameter lists are updated from the centralized directory server by first inputting changes to the system security configuration in the directory server and then downloading these changes to the plurality of servers. The changes are used by the plurality of servers to update the security parameter lists associated with the files/resources of the server.
    • 一种用于从集中式目录服务器更新多个服务器的安全配置的系统,装置和方法。 该系统包括集中式目录服务器和多个服务器,其提供资源和存储供系统用户使用的文件。 与服务器相关联的每个文件/资源​​包括识别文件/资源​​的授权用户的安全参数列表。 通过首先向目录服务器中的系统安全配置输入更改,然后将这些更改下载到多个服务器,从集中式目录服务器更新安全参数列表。 这些更改由多个服务器用于更新与服务器的文件/资源​​相关联的安全参数列表。

    • A unidirectional sprocket includes a hub and a series of radially arrayed sprocket teeth. Each of the sprocket teeth include a root at the point of connection with the hub, a radially extending split body and twin outwardly projecting points at the distal or outermost end. Forward and rearward flanks extend from the root radially outwardly, while forward and rearward faces extend radially inwardly from the pitch circle. Each of the sprocket teeth is asymmetrical with a forward offset. Thus, the point is shifted in the drive direction toward the forward face and flank, and shifted away from the rearward face and flank. Each of the teeth also includes a forward landing area formed above the forward flank and a rearward landing area formed above the rearward flank. Together, the forward and rearward faces and landing areas of adjacent teeth define a split chain link seat for engaging the chain being driven. The rearward landing area is longer than the forward landing area due to the forward offset, and the forward landing area is raised with respect to the rearward landing area.
    • 单向链轮包括轮毂和一系列径向排列的链轮齿。 每个链轮齿包括在与毂的连接点处的根部,在远端或最外端处具有径向延伸的分裂体和双向向外突出的点。 前后侧面从根部径向向外延伸,而前后面从节圆径向向内延伸。 每个链轮齿是不对称的,具有向前偏移。 因此,该点在驱动方向上朝向前面和侧面移动,并且从后表面和侧面移开。 每个齿还包括形成在前侧面上方的前着陆区域和形成在后侧面上方的向后着陆区域。 一起,相邻齿的前后面和着陆区域限定了用于接合被驱动链条的分离链节座。 由于向前偏移,向后着陆区域比前着陆区域长,并且向前着陆区域相对于向后着落区域升高。
