    Abstract: A method and system for pumping unit with an elastic rod system is applied to maximize fluid production. The maximum stroke of the pump and the shortest cycle time are calculated based on all static and dynamic properties of downhole and surface components without a limitation to angular speed of the prime mover. Limitations of structural and fatigue strength are incorporated into the optimization calculation to ensure safe operation while maximizing pumped volume and minimizing energy consumption. Calculated optimal prime mover speed is applied to the sucker rod pump by means of beam pumping, long stroke or hydraulic pumping unit by controlling velocity, acceleration and torque of the electric prime mover or by controlling pressure and flow rate in hydraulically actuated sucker rod pumping system.

    Abstract: A two stage reciprocating compressor and associated HVAC systems and methods are disclosed. The reciprocating compressor includes a crankshaft having an eccentric crankpin, a reversible motor for rotating the crankshaft in a forward and a reverse direction, and an eccentric, two position cam rotatably mounted over the crankpin. The crankshaft and cam combine to cause the piston to have a first stroke when the motor operates in the forward direction and a second stroke when the motor operates in the reverse direction. The cam and crankpin also include stabilization means to restrict the relative rotation of the cam about the crankpin. A lubrication system is provided to lubricate the engaging surfaces of the crankshaft and cam and between the cam and the bearing surface of the connecting rod. There is also provided a control for selectively operating the motor either in the forward direction at a first power load or in the reverse direction at a reduced second power load. A protector for the motor is also provided. In addition, the application of the reciprocating compressor to both air conditioning and heat pump systems is disclosed.

    Abstract: A two-stage reciprocating compressor is provided. The compressor includes a reversible motor that rotates a crankshaft. The crankshaft is connected to a piston by a mechanical system. The mechanical system drives the piston at a full stroke between a bottom position and a top dead center position when the motor is operated in a forward direction. The mechanical system drives the piston at a reduced stroke between an intermediate position and the top dead center position when the motor is operated in the reverse direction. The compressor also includes a control for selectively operating the motor in either the forward direction at a first preselected, fixed speed or in the reverse direction at a second preselected fixed speed.

    Abstract: A condiment dispensing apparatus for dispensing condiments from a bag-in-box type container (108). There is a high durometer compressible elastomeric liquid flow tube (14), an infeed and outfeed thereto and therefrom, and a movable anvil (26) with a round surface to compress the tube. There is an opposed stationary anvil (28) which holds the tube for compression by the movable anvil. The tube is held between the anvils (26, 28) in a slightly compressed state even when the anvil is retracted. There is a control assembly (fig. 15) that causes extension and retraction of the movable anvil to cause flow through the tube, and subsequent delivery of condiment to a dispensing fixture (110).

    Abstract: A hydraulic oil well pump drive system (100) for driving an oil well sucker rod (not shown) includes a master piston (158) positioned within a master cylinder (156) for axial displacement between first and second ends of the master cylinder (156). The master piston (158) has a piston drive rod (164) which extends through one end of the master cylinder (156). The drive rod (164) is connected to a crankpin (147) of an eccentric crank (144). The eccentric crank (144) is driven at a constant rotational speed to reciprocate the master piston (158) within the master cylinder (156) at a sinusoidal rate. A center seal assembly (168) divides the master cylinder (156) into a working chamber (170) and a pressure chamber (172) in opposite ends of the master cylinder (156). Each respective chamber defines a fluid volume which varies with the displacement of the master piston (158). The master piston (158) displacement creates a bi-directional flow of working fluid from the working chamber (170). A wellhead hydraulic assembly (111) is operably connected to the oil well sucker rod and is in fluid communication with the master cylinder working chamber (170) to receive the working fluid flow. The wellhead hydraulic assembly (111) is responsive to the working fluid flow to reciprocate an oil well sucker rod at a rate which relates to the rate of master piston (158) displacement. A gas accumulator (176) is in fluid communication with the master cylinder pressure chamber (172) to bias the master piston (158) toward the master cylinder working end, providing an upward biasing force at the wellhead hydraulic assembly (111).
