    Abstract: A hydraulic motor has a longitudinally extended piston cylinder divided longitudinally into two separate and distinct fluid passages by a central divider. Longitudinally midway about the extended piston cylinder is attached a large center piston which provides the primary driving force for operation of the hydraulic motor. Pressurized fluid passes through one fluid passageway formed by the extended cylinder and central divider, and then through ports formed in the piston cylinder into a chamber. The pressurized fluid drives the large center piston, and therefore the piston cylinder, towards the source of fluid pressure being admitted into the piston cylinder. Pressurized fluid is thereby ported from a pressure chamber through the cylinder beyond the longitudinal midway point, and then passed through the cylinder wall to the power piston surface. In a similar manner, vacuum fluid is admitted into the remaining fluid passageway within the piston cylinder from an end opposite of the pressure fluid, and passed beyond the longitudinal midway point where it passes through the cylinder wall to the power piston on a surface opposite of the pressurized fluid. A power plant using the motor and an energy converter are also disclosed.

    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 method and apparatus for analyzing the operating condition of a machine, such as a reciprocating compressor (10), is provided. The method comprises testing for fluid flow across the closed suction and discharge valves (30-33), as well as leakage across the piston (16), when the machine is in a non-operating condition. The test apparatus may be removable attached externally to the machine by connection to the Kiene head end indicator cock (22) and the crank end indicator cock (24) or the apparatus may be built in internally of the machine.

    Abstract: A fluid pump mechanism for delivering a smooth output of fluids to a system utilizing at least one piston in a chamber reciprocative therewithin. The piston has strokes that fill and empty the chamber in conjunction with the action of valve means located at the inlet and outlet of the chamber. Motive means causes reciprocation of the piston within the chamber. Control means is also included for minimizing the time during the piston cycle in which the piston is not emptying the chamber. The invention's scope also encompasses a pressure metering device for a fluid forcing means motivated by an electrical motor.

    Abstract: A piston monitoring assembly includes a magnetic body coupled to a piston that is configured to move in opposite directions during a piston stroke to dispense a fluid, a magnetic sensor configured to output signals representative of a magnetic field generated by the magnetic body, and a controller configured to examine the signals output by the magnetic sensor and to determine whether the piston is moving far enough to ensure that the fluid is being dispensed during a first movement of the piston in the piston stroke and that the fluid is prevented from being dispensed during a second movement of the piston in the piston stroke.

    Abstract: A machine monitoring system automatically determines an optimal trigger angle for monitoring the rod drop of a reciprocating compressor, and sets the trigger angle configuration value accordingly. A key pulse is monitored using a key phase sensor, the amplitude of the rod drop transducer voltage versus time (or rotation angle) is analyzed, and a position of the minimal change in slope of the rod drop transducer voltage signal relative to the key mark is determined. The optimal trigger angle is determined based on this temporal position, the current speed and the configured piston angle. The optimal trigger angle is provided to the machine monitoring system for configuration. The system thereby relieves the service engineer from having to test several trigger angles with manually-operated test instruments to determine the optimal trigger angle.
