    摘要: A rotary actuated valve choke or the like is remotely controlled by motor means fixedly mounted with respect to said valve to rotationally drive a stem thereof. Monitoring means measure the rotation of the motor and/or its associated drive train. The monitoring means convert the rotary motion to a more easily measurable linear motion to measure the valve setting and appropriately control the energization of the motor in response thereto.

    摘要: The subject device has a pair of conical segment members extending downstream from a central chamber and provided with means to relatively rotate them to proportion the flow of the non-predominant (volumetric-wise) phase of two-phase fluid therethrough. Relative positioning of the conical segment members forces the two-phase mixture streams to change velocities and mix the liquid phase with the gaseous phase prior to their encountering a flow-splitting device such as a tee junction.
