| 20090324382 | Torque-based sensor and control method for varying gas-liquid fractions of fluids for turbomachines - A torque-based sensor and control method for detecting varying gas-liquid fractions of a fluid entering a turbomachine that operates a fluid of varying liquid phases and compositions and using information about the actual gas-liquid fraction to set a control algorithm so that it can change the torque and therefore the rotation speed of the turbomachine to operate at safer conditions or conditions with higher efficiency or higher power output. | 12-31-2009 |
| 20100011875 | SYSTEM AND METHOD TO MINIMIZE IMPACT OF SLUG EVENTS - A system for stabilizing flow in a pipeline is provided. The system includes at least one of an internal supply or an external supply configured to provide fluid into the pipeline such that a ratio of liquid to gas in the flow is within an acceptable range. The system also includes one or more sensors configured to indicate the ratio of liquid to gas in the fluid. The system further includes at least one valve configured to regulate a flow of the fluid from the internal supply or the external supply into the pipeline based upon the ratio indicated by the one or more sensors. | 01-21-2010 |
| 20100011876 | CONTROL SYSTEM AND METHOD TO DETECT AND MINIMIZE IMPACT OF SLUG EVENTS - A system for detecting and controlling a slug event in a flow through a pipeline is provided. The system includes multiple sensors configured to indicate one or more parameters of the flow for a slug at multiple locations in the pipeline. The system also includes a controller configured to receive one or more response signals corresponding to at least one of the parameters from the sensors. The system further includes a variable speed drive system electrically coupled to the controller and a compressor pumping fluid in the pipeline such that a ratio of liquid to gas is within an acceptable range, wherein the variable speed drive is configured to receive one or more signals from the controller and further configured to regulate at least one of a translational or a rotational speed or a power of the compressor based upon the signals. The system also includes a display unit coupled to the controller, the display unit configured to output the plurality of signals received from the controller. | 01-21-2010 |
| 20100140519 | ELECTROMAGNETIC ACTUATORS - A valve includes a valve plate coupled to the movable device disposed partially within a housing. An electromagnetic actuator includes a first set of permanent magnets provided to the movable device. At least one stator core is disposed proximate to the movable device with a gap between the stator core and the movable device. At least one stator coil is wound to each stator core. A power source is coupled to the at least one stator coil and configured to supply electric current to the at least one stator coil. The opening and closing of the valve plate is controlled by changing direction of electric current flow through the at least one stator coil. | 06-10-2010 |
