Abstract: A preloaded assembly (100) in accordance with the invention includes a stationary bushing (14) having an annulus (18); a shaft (12) having a first thermal coefficient of expansion with the shaft being mounted for rotation in the annulus of the stationary bushing; a first sleeve (102) which contacts the first shaft along a first portion (106) of an outside surface (104) of the shaft with the first sleeve having a second thermal coefficient of expansion; and a second sleeve (108) having a third thermal coefficient of expansion, an outer surface (22) facing the annulus of the stationary bushing and an annulus with a first axial section (114) of the annulus of the second sleeve containing a second portion (112) of the outside surface of the shaft adjacent the first portion and a second axial section (116) of the annulus of the second sleeve contacting an outside surface (118) of the first sleeve.

Abstract: The current invention detects malfunctions in a variable flow delivery pump. These malfunctions prevent the pump from sustaining inherently high accuracy and/or cause damages to the pump. The invention detects the malfunctions without comparing sampled values to a preset absolute value. A malfunction is determined by a pattern of force measured by a current sensor (6) exerted on a displacement pump in relation to the displacement positions sensed by a signal generator (5). The pattern is compared to an empirically established range of pattern values by a computer (7). Once a malfunction is determined, the computer (7) responds by sounding an alarm (10) and suspending pump operation.

Abstract: In a streaming current detector (H-13, 18-20, 22-24, 26) a standard calibration solution is used to calibrate the streaming current signal representing the charged condition in a sample fluid containing particles. The standard calibration solution is electrokinetically stable over a wide range of pH and concentration. Calibration allows direct comparison of readings from different streaming current detectors.

Abstract: A beverage dispenser which can dispense carbonated beverages and/or uncarbonated beverages. The problem with beverage dispensers is the utilization of a number of pumps and motors which makes the system large. The invention employs a single integral cylinder with the chambers to receive pistons for the various liquids. The dispenser (10) includes a cylinder (12) having first (14) and second (16) chambers. A first piston (18) is in the first chamber (14). A rod (20) extends from the first piston (18) into the second chamber (16) and has a second piston (22). The retraction of the piston (18, 22) will draw liquids into the chambers (14, 16) and upon compression of the pistons (18, 22) the liquids will be directed into a mixing chamber (42) then into a drinking container (66).
