Abstract: There is provided a method of shutting down an engine, the engine having an air intake, and the method having the steps of attaching a valve to the air intake, the valve having an open position that allows air to pass into the air intake; using one or more sensors, detecting one or more predetermined engine conditions indicative of a runaway state; electromagnetically actuating the valve to move to a closed position preventing air from passing into the air intake once the one or more predetermined engine conditions have been detected; and causing the valve to return to the open position once a predetermined safe state has been reached.

Abstract: An apparatus for reducing operating costs, maintenance costs and emissions in a fluid injection system, which includes a valve assembly adapted to be connected to a fluid injection point located on a well. The valve assembly has an electronic controller, a flow passage, a plurality of solenoid valves positioned in the flow passage, and a metering chamber positioned in the flow passage that is adapted to receive and discharge fluid flowing through the flow passage into the injection point. The electronic controller supplies signals to selectively open and close each of the plurality of solenoid valves to control the flow of the fluid along the flow passage into the metering chamber and to control the discharge of the fluid from the metering chamber along the flow passage into the injection point.

Abstract: A method and apparatus for reducing operating costs and emissions in a pumping installation. A first step involves providing a flow dividing apparatus capable of dividing flow from a pump. The apparatus has a single inlet and two or more outlets. A second step involves coupling the flow dividing apparatus with a pump of the pumping installation and directing flow from the pump through the single inlet of the flow dividing apparatus. The pump will generate a flow stream from each of the two or more outlets and perform work that, in the absence of the flow dividing apparatus, would have to be performed by two or more pumps. The reduction in the number of pumps used necessarily reduces both operating costs and emissions.
