  • Patent number: 11952860
    Abstract: A staged cementing device includes a cylindrical body having an inner chamber. A circulating opening and a liquid inlet recess open to the inner chamber are arranged on a wall of the body. An opening assembly is arranged in the body, which has an opening sleeve and an opening seat located in the opening sleeve. Initially the opening sleeve is connected with the body through a first shear pin and covers the circulating opening, and the opening seat is connected with the opening sleeve through a second shear pin and covers the liquid inlet recess. A packer includes a packing valve body and a packer rubber. The packing valve body includes a flow channel in communication with the liquid inlet recess, and the packer rubber includes a liquid reservoir in communication with the flow channel. The second shear pin is sheared off in response to primary cementing procedure.

  • Patent number: 10618532
    Abstract: The present invention discloses a train coupler structural health monitoring system. The system includes one or more sensors mounted to or integrated with the train coupler, a data acquisition unit for receiving signal or data from the sensors, and a processing unit for determining the train coupler's structural health based on the received signal or data. Inspections via the system can be performed in real time continuously or periodically while a train is in service. It can also be performed offline while a train is not in service. Inspection method can be either passive, where sensors collect signals without generating excitation signals to the structure, or active, where some sensors are used as actuators to actively send excitation signals to the structure and other sensors or the actuators themselves collect the structural response signals. The data acquisition unit receives signals or data from sensors.
