Abstract: A computer-based system for taking the physical inventory of beverages dispensed in full and partially full containers so as to effectively control the theft and overpouring. The products to be inventoried, such as liquor bottles are identified by conventional barcodes that can be scanned by a scanner that is operably interconnected with a hand-held computer. The step of scanning the barcodes produces, on the touch-sensitive screen of the hand-held computer, product information concerning the product contained within the scanned bottle including a silhouette of the bottle. In accomplishing the inventory, the user indicates by touching on the silhouette of the bottle the fluid level within the bottle. This information is inputted in the computer data storage and is used to calculate the volume of beverage remaining in the bottle.

Abstract: A fluid dispensing control for controlling the dispensing of a fluid by a metering valve through a nozzle onto a workpiece. An initial value of a flow characteristic of the fluid is determined that is correlated to the relationship between the flow rate of the fluid and nozzle pressure. Desired nozzle pressure values are periodically determined by evaluating a model of flow rate of the fluid through nozzle in response to the initial value of the flow characteristic and a desired flow rate value. Thereafter, the control provides command signals to the metering valve as a function of the desired nozzle pressures. A new value of the flow characteristic is determined as a function of the measured volume of fluid dispensed during the dispensing cycle to the measured nozzle pressure. During a subsequent dispensing cycle, the control determines the desired nozzle pressures by evaluating the model of flow rate of the fluid through the nozzle as a function of the new value of the flow characteristic.

Abstract: Disclosed is a method and apparatus for intermittently dispensing a flowable foodstuff such as a sausage material into a container, e.g. a sausage casing, in portions of a predetermined size. A conveyor dispenses the foodstuff into the container and is deactivated when a quantity of the foodstuff has been placed into the container which is slightly less than the desired portion. After deactivation a small terminal mass of the foodstuff continues to flow into the container and the terminal mass represents the remainder to bring the dispensed foodstuff up to the desired portion. During each operating cycle the terminal mass is measured and this measurement is used during the next operating cycle to determine when the conveyor should be deactivated so that the next terminal mass brings the just dispensed portion up to the desired level.

Abstract: Apparatus for controlling the feed rate and batch size of the material feeder is disclosed. A signal generator computes the weight of material delivered by the material feeder and compares it to first and second presettable values. When the weight of material delivered by the feeder is less than the first presettable value, the signal generator enables a first pulse generator which generates a pulse train having a relatively high pulse repetition frequency. This pulse train is applied to a motor speed controller which causes the feeder to deliver material at a relatively high rate. When the weight of material delivered by the feeder reaches the first presettable value, the signal generator enables a second pulse generator and disenables the first pulse generator. The second pulse generator generates a pulse train having a pulse repetition frequency substantially lower than that of the pulse train generated by the first pulse generator.
