Abstract: A controller controlling the dispensing of paper currency including a microprocessor for controlling motors which feed a predetermined mix of paper currency from each dispensing device to a common acceleration device which advances bills to an output stacker. Each individual dispensing device dispenses the proper number of bills to the acceleration device. Apparatus multiplexes the control signals to the stepper motor. After the bills have been dispensed, the stepper motor is halted, and a home positioning sensor determines if the stepper motor has been halted in the proper position. Sensors provided at spaced intervals along the common acceleration device determine if bills have reached the acceleration device. The dispensing operation is repeated if bills do not reach the sensor. The sensors perform the dual function of sensing advancement of a bill and detecting overlapping or multiple fed bills. The adaptive technique compensates for changes in the sensor such as component aging and dust accumulation.

Abstract: A mechanism for use with a sheet transport apparatus for turning over a sheet transported along a travel path, such mechanism reliably functioning irrespective of sheet weight or size. With the mechanism, a sheet is selectively moved in one direction from a travel path or in an opposite direction into such travel path. The surface of the moving sheet is engaged so that energy derived by the sheet being transported in the direction from the travel path is stored. When the sheet is no longer being transported in such direction, the stored energy is utilized to move the sheet in the opposite direction to a point where it can be transported in such opposite direction back into the travel path with its trail edge becoming the lead edge and its surface orientation reversed.

Abstract: There is disclosed a flexible, hollow, tubular member for conducting a fluid therethrough to cause the tubular member to move in a whip-like manner inside a container. The conduction of fluid therethrough causes the tubular member to move in a generally upward direction through material in the container while producing whip-like motions of the tubular member to agitate compacted portions of the material and cause the material to discharge from the container. The container may include a passageway covered by an entry/sealing means which includes a one way flap or a flexible tubular housing to permit insertion of the tubular member enclosed by a tubular housing into the container, while preventing the escape of material from the container when the tubular member/housing has been removed. Retraction of the tubular housing relative to the flexible tubular member providing a substantially exposed section of the tubular member to allow for the random, whip-like movement of the tubular member in the container.

Abstract: An apparatus for arranging the obverse and reverse sides of the bills or the like includes a carrying-in passage and a carrying-out passage. A reversible conveying passage is provided between the carrying-in passage and the carrying-out passage for conveying the bills from the carrying-in passage in a direction identical or opposite to the carrying-in passage.

Abstract: A process, apparatus, and system are provided for preserving and dispensing wine from a bottle or other container. The process involves directing a chemically inert gas under pressure from a reservoir to a bottle containing a wine. The pressure of the gas is reduced prior to its introduction into the bottle. The bottle is positioned generally vertically within a hermetically and thermally sealed enclosure. A gas flow line enters the bottle and has a first end connected to a gas source and a second end which terminates within the bottle between a bottle plug and the contained liquid. By passing the gas into the bottle, liquid within the bottle is forced through an end of a second line which is positioned in the wine to a second end of the line positioned on the exterior of the bottle. The flow of wine is caused by the introduction of gas under pressure into the interior of the bottle between the bottle plug and the wine.

Abstract: A sheet stacker, e.g. for a photocopier, providing accurate trail edge registration includes co-acting driven output rollers associated with a sheet guide for directing sheets in an upwardly inclined direction. An output tray for receiving sheets exiting the output rollers has a support face inclined upwardly in the direction of sheet travel at an angle greater than that imparted to the approaching sheets such that the leading edges of the sheet contact the support face before the trail edges exit the output rollers. The output tray also includes a base edge support which, in the plane of the support face, is inclined downwardly and comprises at the lower end a corner registration stop. A fulcrum is provided at the upper end of the base edge support and is arranged such that after exiting the output rollers the sheets slide under their own weight, trail edge first, down the support face and abut the fulcrum intermediate their edges remote from the registration corner stop and the center of the sheets.

Abstract: A hot melt foam adhesive system including a gear pump wherein gas is mixed under pressure into the molten adhesive and is driven into solution with the adhesive. The gas is supplied to the pump via a one-way check valve operative to prevent the back flow of molten adhesive to a gas flow control valve, regulator, and gauge. The check valve is positioned above the level of the pump so that molten adhesive cannot flow by gravity into the check valve. The check valve is so constructed that it is biased into a closed position by a spring on the gas side of the valve so that adhesive cannot collect around and foul the spring of the valve.

Abstract: A dispenser for liquids and viscous fluids has a syringe-like device with a barrel for containing fluid and a nozzle at one end. The plunger is movable axially in the barrel for discharging the fluid. At the inner end of the plunger is a flexible, elastic cap which has an end wall that is normally concave, but which is flattened out under pressure when the fluid is discharged. When pressure on the cap is removed, the cap reassumes its concave shape thereby creating a suction in the barrel which draws fluid back into the nozzle to prevent dripping.
