    摘要： A control for a beverage dispenser monitors operation thereof to sense a beverage sold out condition. The control senses the voltage demand of a pump motor as it pumps the beverage from a source thereof to a dispensing valve. If the sensed voltage is high, that indicates the pump is encountering resistance and fluid is present. Conversely, if the sensed voltage use is low, that is taken to indicate that the pump is not pumping any liquid and that the container is empty. A software routine is used to sense the average current requirements during dispensing and adjust the reference voltage for the normal full reservoir pump current value based on a historical average thereof as indicated by a predetermined number of prior dispense cycles. The control uses the adjusted reference voltage as a base for determining a sold out condition. Thus, the control of the present invention has the ability to learn over time and to compensate for physical changes in hardware and in the environment to provide for accurate sold-out determinations. The control senses an sold out condition in one of two ways. If the control senses a large variation between voltage samplings during a dispense cycle, that is taken to indicate a situation where the syrup or beverage is running out. If there is no significant difference between the sensed voltages, but the sensed voltage is significantly below the reference voltage that would be expected if fluid were present, that also indicates a sold out condition.

    摘要翻译： 饮料分配器的控制器监视其操作以感测饮料销售状况。 当泵电动机将其从其源泵送到分配阀时，该控制器检测泵电动机的电压需求。 如果检测到的电压较高，则表明泵遇到阻力并且流体存在。 相反，如果检测到的电压使用量低，则表示泵没有泵送任何液体并且容器是空的。 使用软件程序来感测分配期间的平均电流要求，并根据其历史平均值调整正常全储层泵电流值的参考电压，如由预定数量的先前分配周期所指示的。 该控制使用调整的参考电压作为确定售罄状态的基础。 因此，本发明的控制具有随着时间的推移学习的能力，并且补偿硬件和环境中的物理变化以提供准确的售罄决定。 控制器以两种方式之一感知出售条件。 如果控制器在分配循环期间感测到电压采样之间的大变化，则表示糖浆或饮料用尽的情况。 如果感测到的电压之间没有显着差异，但是感测到的电压明显低于如果存在流体时预期的参考电压，那么也表示售罄状态。

    摘要： A syrup dispensing system for use in a soft drink dispenser. Sensors are placed in the syrup dispensing flow path to measure the rate of flow of the syrup at the commencement of a dispensing cycle. In a first embodiment of the invention, a regulatable pressure source is then adjusted during the remainder of the dispensing cycle to assure that a full measure of syrup is dispensed. In another embodiment of the invention, the period of time during which the dispensing valve in open is then modified as a function of the flow rate to assure that a full measure of syrup is dispensed.

    摘要： Drink dispensing apparatus is presented wherein a system including plural dispensing terminals communicates with a central source of beverage ingredients for dispensing. Each of the terminals is interconnected with a central microprocessor which communicates with each of the terminals and the source of beverage ingredients to dispense to the respective terminals the particular formulations selected thereat. Further presented is circuitry interfacing the microprocessor with the various terminals such that automatic pricing, inventory control, sales totalization, and other housekeeping techniques may be performed by the microprocessor on a terminal-by-terminal basis.

    摘要： The present invention is an apparatus and method that regulates the size of an ice bank (50) and that prevents short cycling of the compressor (30) therefor and operation thereof at undesired voltages. A microprocessor based control circuit (10) includes a circuit for sensing line voltage (14) combined with an ice bank sensing circuit (18, 20). The ice bank sensing circuit is of the conductivity sensing type wherein the electrical conductivity between two probes (P1, P2) is sensed. The microprocessor (16) continually monitors the probes (P1, P2) to determine if refrigeration is needed or not, and continually senses the line voltage to determine if that voltage is within the design limits of the refrigeration compressor (30). The voltage sensing circuit (14) can also sense if power has been interrupted where the voltage drops to zero.

    摘要： A carbonation system employing a pneumatic pump which operates off of a pressurized source of carbon dioxide which is itself employed for the carbonation process. The pneumatic pump serves as both a precarbonation chamber and a reservoir for receiving water from a low pressure source and subsequently transferring precarbonated water to a carbonation tank. Sensors within the pneumatic pump assure that a proper volume of water is maintained within the precarbonation chamber and available for transfer to the tank. Both the pneumatic pump and the carbonation tank operate off of the same supply of pressurized carbon dioxide, but the pressure provided to the tank is slightly less than that presented to the pneumatic pump.
