    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 controller is provided to control and fix the stroke and frequency of the piston movement of the compressor under various operating conditions. The controller includes a signal generator for providing a first signal, a detector generating a second signal after detecting that the piston has a displacement, and a signal processing unit electrically connected to the signal generator and the detector for outputting a control signal to the compressor after receiving the first signal and the second signal to control a movement of the piston.

    Abstract: A fluid powered diaphragm pump with an adjustable stroke is provided. The stroke of the pump is adjusted by providing an inner diaphragm plate assembly that includes a retractable piston. The piston is biased towards the inner plate by one or more standoffs that attach the piston to the plate. The bias of the piston is overcome by pressurized fluid that is communicated to a chamber defined by the piston and the inner plate. The fluid may be communicated to the chamber through the diaphragm rod. The inner diaphragm plate assemblies of both diaphragm chambers may be connected to different pressurized fluid supplies there enabling the stroke or capacity of the two diaphragm chambers to be controlled independently. As a result, the stroke or capacity of the two diaphragm chambers may differ.

    Abstract: A hydraulic oil well pump drive system for driving an oil well sucker rod includes a master piston positioned within a master cylinder for axial displacement between first and second ends of the master cylinder. The master piston has a piston drive rod which extends through one end of the master cylinder. The drive rod is connected to a crank pin of an eccentric crank. A center seal assembly divides the master cylinder into a working chamber and a pressure chamber in opposite ends of the master cylinder. Each respective chamber defines a fluid volume which varies with the displacement of the master piston. The master piston displacement creates a bi-directional flow of working fluid from the working chamber. A wellhead hydraulic assembly is operably connected to the oil well sucker rod and is in fluid communication with the master cylinder working chamber to receive the working fluid flow. The wellhead hydraulic assembly 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 displacement. A gas accumulator is in fluid communication with the master cylinder pressure chamber to bias the master piston toward the master cylinder working end, providing an upward biasing force at the wellhead hydraulic assembly.

    Abstract: In at least one illustrative embodiment, a diaphragm pump may comprise a housing defining a first pumping chamber, a second pumping chamber, and a hydraulic fluid chamber, a first flexible diaphragm separating the first pumping chamber from the hydraulic fluid chamber, a second flexible diaphragm separating the second pumping chamber from the hydraulic fluid chamber, a rod mechanically linking the first flexible diaphragm and the second flexible diaphragm such that an expansion of one of the first and second flexible diaphragms exerts a contraction force on the other of the first and second flexible diaphragms, and a piston disposed within the hydraulic fluid chamber and configured to reciprocate to cause a hydraulic fluid contained within the hydraulic fluid chamber to alternately exert an expansion force on the first and second flexible diaphragms.
