Abstract: An automatic beverage dispenser having a multiflavor automatic beverage dispensing valve (faucet) and including means for preventing color and flavor carryover from one drink to the next. The automatic dispenser includes an electronic control system with an on-board computer with a microprocessor which, when a drink vend signal is received by the electronic control system, first checks to determine whether a dark or light colored drink was requested, then checks the last vend to determine if it was a light or dark drink. If the drink ordered was a light drink and the previous drink was a dark drink, then the controller looks to see if the cup dispenser position is occupied. If it is occupied, the flush is delayed until it is free when the soda water will flush to cleanse the nozzle. After flushing, the vend is processed.

Abstract: A postmix valve for a beverage dispenser, including a volumetric ratio control device incorporated therein to provide positive ratio control. The device includes a double acting piston including a syrup piston and a soda piston linked together, syrup and soda chambers, and valve device for controlling the flow to and from the chambers. The soda pressure drives the pistons. The valve device includes paddle valves. This valve can be used with any of a figal, a bag-in-box, a gravity tank, or a non-returnable container under no pressure or under a low pressure of 5 to 10 psig.

Abstract: Methods of discriminating between contaminated and uncontaminated containers prior to washing is disclosed characterized by the testing of the residue of the container to determine if the residue is residue of the original product packed in the container. If the residue is not sufficiently similar to the original product, the container is rejected as contaminated.

Abstract: A disposable and recyclable plastic container for use in a post-mix beverage dispensing system includes first and second openings at a top end thereof. The container may be filled with syrup through the first opening and withdrawn by a pump through the second opening. The second opening is defined by an upper end of a tube, which is integrally formed with the container by blow-molding. The tube extends from the top end of the container, down the exterior of the container sidewall and through the bottom. As syrup is withdrawn, the first opening, or an associated vent, vents the container to assist the withdrawl of syrup. The second opening and tube have a valve actuator therein for a spring-loaded valve in a conventional quick-disconnect coupling such as used in bag-in-box type systems. The top and bottom of the container have complementary shapes to permit vertical nesting and stacking of plural like containers.

Abstract: A microprocessor based control system including an electrical unit attached to a postmix beverage dispensing valve for performing the three functions of: portion control, reminding the operator to check the ratio, and adjusting the ratio. The portion control operation can be identical to known portion control devices. The reminder function can turn on a light every two weeks, for example. In the ratio adjusting function, the operator puts a single cup under the valve, pushes "Small" to dispense syrup for a predetermined time period which should result in the dispensing of a predetermined volume of syrup, measures the exact volume actually dispensed, and then adjusts the syrup flow control accordingly until the exact predetermined volume is dispensed, and repeats the operation for water in the same cup but to a different predetermined volume. The flow rate can accurately be set at the same time as the ratio.

Abstract: A post-mix dispensing valve for a beverage dispenser, including a self-contained volumetric ratio control device incorporated therein to provide positive ratio control. The device includes a single piston in a single cyinder, syrup and soda chambers, and self-contained direct acting electrical solenoid valve for controlling the flow through the volumetric ratio control device and the reciprocating action of the piston. The soda pressure drives the piston. This post-mix dispensing valve can be used with any of a figal, a bag-in-box, a gravity tank, or a non-returnable container under no pressure or under a low pressure of 5 to 10 psig. This invention also includes a non-returnable, pressurizable syrup container.

Abstract: An automatic beverage dispensing system including a conveyor, a multiflavor valve, and a programmable cup drop system which includes means for searching through a plurality of separate cup supply tubes for a cup of the selected size.

Abstract: A dosing system has a vessel for holding a fluid and a dosing device for dispensing a measured quantity of fluid from the vessel. The dosing device hermetically seals the vessel and has a valve with a fluid passage, a piston surrounding the valve and a cylinder housing surrounding the piston. The valve is positioned in a first position wherein fluid is gravity fed from the vessel to a chamber formed between a drive face of the piston and the cylinder housing. The valve can be reciprocated from the first position to a second position whereat the valve closes the inlet from the vessel to the chamber. The piston closes the passage within the valve when the valve is in the first position and opens the passage when the valve is moved to the second position to permit discharge of fluid from the chamber. When the valve moves to a third position, the drive face of the piston moves toward a shoulder of the cylinder housing to thereby pump the fluid from the chamber.

Abstract: The present invention provides a method for the enzymatic synthesis of peptides accomplished by shifting the chemical equilibrium that exists in a reaction mixture between charged or ionized reacting amino acids and uncharged or non-ionized peptide product in the presence of a proteolytic enzyme such as thermolysin. The equilibrium is shifted by diffusion of the uncharged peptide product across an ion-rejection membrane which removes the uncharged peptide from the reaction mixture and preferably the diffused uncharged peptide is quickly converted to a charged species that cannot back-diffuse into the reaction mixture so that the uncharged peptide is effectively "pulled" across the membrane.
