Abstract: A oil and gas compression system is generally presented. The compression system includes a driver, a driver starter, and an input expansion unit. The expansion unit may include a plurality of inputs configured to receive feedback from the compression system, a processor configured to receive the plurality of inputs and send an output signal to the driver starter to start or stop the driver, and an indication panel configured to indicate the presence of an input condition. The input expansion unit may be configured to store a history of received input conditions and display the history on the indication panel upon request.

Abstract: An actuator linkage for imparting a rotating motion to a clutch operating shaft according to one embodiment of the present invention comprises a linear actuator including an extendable and retractable arm, the arm including a pivot end, a linkage bar having a first pivot location and an oppositely-disposed second pivot location, a slotted linkage bar having a first pivot location and an oppositely-disposed second pivot location having the shape of a slot, a control link having a first end constructed and arranged to connect to the control shaft and a second end defining a pivot location, wherein the pivot end of the extendable and retractable arm, the first pivot location of the linkage bar, and the first pivot location of the slotted linkage are pivotally connected together, and the control link being constructed and arranged to move from a first slack position through a clutch operating shaft over-center position to a second slack position with movement of the extendable and retractable arm.
