Abstract: A sensorless method and apparatus for detecting piston collisions in a free piston linear compressor motor. The waveform of the back EMF induced in the motor stator windings is analysed for slope discontinuities and other aberrations in a time window centred on the back EMF zero-crossings. Waveform slope artefacts are indicative of piston collisions and cause the motor power to be decremented in response.

Abstract: To provide performance particularly in handling supercritical extraction systems, a specially designed pump includes a cam-driven, single-plunger with a cam having a profile that enables the pumping system to avoid destructive reverse torque on the cam, gear train and drive motor after the cam passes top dead center. The plunger includes a seal having one side in contact with the supercritical fluid and a mechanism for supporting and aligning the piston on the other side of the seal to maintain the piston in alignment. The piston drive has Hertzian contact with the piston. The fluid volume leaving the pump is determined by measuring only pressure or other parameters related to flow and movement of the plunger. Measurement of the fluid volume leaving the pump is useful for recording or indicating the flow rate while the pump is operating.

Abstract: A system and method for controlling operation of a sludge material handling system is disclosed. The sludge material handling system includes a positive displacement piston/cylinder pump, a sludge material feed system which delivers sludge material to the pump, and a sludge material disposal system which receives and disposes of sludge material from the pump. A first parameter is sensed, the first parameter bearing a known relationship to an actual volume of sludge material delivered during a pumping cycle. An output value is determined from the first parameter. A control signal is provided as a function of the output value.

Abstract: A system for the transport of high solids sludge includes a positive displacement pump for pumping sludge through a pipeline. The volume of sludge transported is accurately measured by determining the fill percentage by using a material flow signal, measured time intervals, hydraulic fluid pressure, or hydraulic fluid flow rate during each pumping cycle.

Abstract: A remote adhesive monitoring system is used in connection with adhesive applied to workpieces moving along a production line. A reservoir, pump, and applicator apply the adhesive to the workpieces. A monitor control computer has an associated data processing program. A pump cycle sensor senses pump cycles. An applicator sensor senses when the adhesive is applied to the workpieces. A workpiece sensor senses the workpieces moving along the line. The monitor control uses input from the applicator sensing means and the workpiece sensor to determine an ON time per each workpiece at a predetermined speed. The monitor control uses input from the workpiece sensor and the pump cycle sensor to determine the number of workpieces per pump cycle. The monitor control calculates an ON time to TOTAL time ratio per each workpiece. The monitor control will then calculate an amount of adhesive used for the given ON time to TOTAL time ratio.

Abstract: An example system for detecting mud pump stroke information comprises a distributed acoustic sensing (DAS) data collection system coupled to a downhole drilling system, a stroke detector coupled to a mud pump of the downhole drilling system configured to detect strokes in the mud pump and to generate mud pump stroke information based on the detected strokes, and a fiber disturber coupled to the stroke detector and to optical fiber of the DAS data collection system configured to disturb the optical fiber based on mud pump stroke information generated by the stroke detector. The system further comprises a computing system comprising a processor, memory, and a pulse detection module operable to transmit optical signals into the optical fiber of the DAS data collection system, receive DAS data signals in response to the transmitted optical signals, and detect mud pump stroke information in the received DAS data signals.
