    • A hydraulic actuator for a valve that fails as-is in the event of control line failure. The actuator has a housing carrying an actuator piston for actuating the valve open or closed. An elongate gripper shaft extends upward from the actuator piston. A collet member is carried within the housing and adapted to engage the gripper shaft when moved upward relative to the housing. The collet member is biased upward by a spring. A release piston abutting the dog members prevents their upward movement when actuated to a lower position. The release piston is supplied with the same hydraulic fluid pressure as the actuator piston. If pressure is removed, the spring moves the collet member into locking engagement with the shaft.
    • 用于阀门的液压执行器,在控制线故障的情况下故障。 致动器具有承载用于致动阀打开或关闭的致动器活塞的壳体。 细长的夹持器轴从致动器活塞向上延伸。 夹套构件被承载在壳体内并且适于当相对于壳体向上移动时接合夹持器轴。 夹头构件被弹簧向上偏置。 抵靠狗构件的释放活塞在致动到较低位置时防止其向上运动。 释放活塞被提供与致动器活塞相同的液压流体压力。 如果压力消除,弹簧将夹头构件与轴锁定接合。

    • A drinking vessel configured to receive and store a liquid being operable to be traversed across a support surface. The drinking vessel includes a body having a bottom and a wall integrally formed to create an interior volume and an opening. The body is superposed a support member wherein the support member includes a first end and a second end that extend beyond the bottom of the body on opposing sides thereof. A first pair of wheels and a second pair of wheels are rotatably secured to the first end and second end of the support member. A first decorative element and a second decorative element are secured to the first end and second end of the support member and are formed to resemble a front end and a rear end of a motor vehicle.

    • A networking system is discussed. The system may be used for industrial networks where access to field device data is valuable. Commands, such as read or write requests to particular field device data, may be encapsulated within messages conforming to an object-oriented protocol, such as, for example, Common Industrial Protocol (CIP). Responses to the commands may also be encapsulated within CIP messages. The encapsulated commands and responses may be transmitted between various devices of an industrial network, including a controller and a gateway device, such as a multiplexer, of the industrial network. Encapsulating the commands and responses may provide a tunneling mechanism allowing a controller complete access to the data of the field devices in communication with the gateway device.
    • 讨论了一个网络系统。 该系统可用于对现场设备数据访问有价值的工业网络。 诸如对于特定现场设备数据的读取或写入请求的命令可以被封装在符合面向对象协议(例如,通用工业协议(CIP))的消息内。 对命令的响应也可以封装在CIP消息中。 封装的命令和响应可以在工业网络的各种设备之间传输,包括工业网络的控制器和网关设备,例如多路复用器。 封装命令和响应可以提供隧道机制,允许控制器完全访问与网关设备通信的现场设备的数据。
