    摘要： A reinforced wellhead member for use during fracing operations. The wellhead member is preloaded at a flange section by creating compressive stresses via a ring that interacts with a tightening nut on a bolt. The bolt is rigidly attached to an adapter which may also be modified to create stresses on the flange of the wellhead member. The induced stresses counter the tensile stresses experienced by the flange during fracing operations, allowing a standard wellhead member to be utilized.

    摘要： A kit for identifying fiber optic connections in a fiber optic cabling system comprises a plurality of indication optic terminators and at least one test light generator. The fiber optic system comprises a patching device, a plurality of ports furnished on the patching device, a plurality of outlets remote from the patching device, and a plurality of fiber optic cables for optically connecting the ports and the outlets. Plurality of indication optic terminators are attached onto each of the ports of the patching device. By using the test light generator to apply a test light to one of the outlets, the test light reaches a corresponding connected port of the patching device through the connection of fiber optic cable so as to make the corresponding indication optic terminator attached onto that connected port to light. Therefore, by repeating the process of distinguishing the light of the indication optic terminator one by one, all of the fiber optic connections between the connected ports and outlets can be identified. After completing the job of fiber optic connection identification, all of the indication optic terminators can be detached and kept for re-use.

    摘要翻译： 用于识别光纤布线系统中的光纤连接的套件包括多个指示光学终端器和至少一个测试光发生器。 该光纤系统包括一个修补装置，在修补装置上设置的多个端口，远离修补装置的多个出口以及用于光学地连接端口和出口的多个光纤电缆。 多个指示光学终端器附着在修补装置的每个端口上。 通过使用测试光发生器将测试光施加到一个出口，测试光通过光纤电缆的连接到达修补设备的对应连接端口，以使相应的指示光学终端器连接到该连接端口 点亮 因此，通过重复将指示光学终端器的光逐一区分的过程，可以识别所连接的端口和出口之间的所有光纤连接。 在完成光纤连接识别工作后，所有指示光学终端器都可以分离并保持重新使用。

    摘要： A valve assembly for use in regulating a fracturing fluid that includes an actuating stem for actuating a gate, a balancing stem, and a backseat on the stem that defines a backseat seal when urged against a profile in the valve assembly. The backseat seal is energized by applying a force to an end of the balancing stem. An end of the balancing stem is enclosed within a plenum, so that the force on an end of the balancing stem can be applied by pressurizing the plenum. The assembly can be on an opposite side of the valve body/bonnet to create a backseat seal on a balancing stem/bonnet to allow changing the stem packing on the balance stem side while maintaining pressure integrity.

    摘要： A group wiring device which has built-in light emitting means and switch mechanism coupled with wire pair receptacle thereof. The switch mechanism is normally on a “CLOSE” status but can be switched to an “OPEN” status when a plug mates with the wire pair receptacle. When the switch mechanism is “CLOSE” and a testing voltage is applied to the circuit of the light emitting means, the light emitting means will emit light for assisting wire pair identification. After the process of wire pair identification is complete, the group wiring device is deemed to be in normal operation, that is, to perform ordinary signal transmitting functions. The wire pair receptacle will then be mated with plug of network cable so as to drive the switch mechanism to become “OPEN”. Therefore, the circuit of light emitting means becomes an open circuit and provides no function at all. As a result, the built-in light emitting means and switch mechanism of the present invention will not result in “loop back shorting” nor disrupt the communication at all.
