Abstract: The present invention comprises a valve assembly with an unbalanced seal between sealing components of the valve assembly. For a gate valve assembly, an upstream seat may have a different outer diameter than a downstream seat, thereby creating an unbalanced seal with the gate. By increasing the sealing surface of the downstream gate/seat interface and by decreasing the sealing surface of the upstream gate/seat interface, the gate/seat interface may seal at lower pressures. A bidirectional seal is also disclosed that may prevent grease or sand from entering a cavity of the seat/pocket insert interface and assists with controlling the pressures and torque on the valve assembly.

Abstract: A computer-implemented labeling technique generates a task description that describes a labeling task to be given to a language model. The technique then sends a prompt to the language model, which includes the task description and a particular item to be labeled. The technique receives a response provided by the language model in response to the prompt, which specifies a class assigned by the language model to the item. In some implementations, the task description specifies a group of suggested classes to be used in classifying the particular item. The task description also invites the language model to specify another class upon a finding that none of the group of suggested classes applies to the item. The technique also allows a user to stop and restart a labeling run at any point in the labeling run. Other aspects of the technique include consensus processing and weight updating.
