Abstract: A system for mixing beverage components in a predetermined ratio is characterized by a housing having a mixing chamber therein, first and second inlets to the chamber and an outlet from the chamber. A first beverage component is flowed through the first inlet to the mixing chamber and a second beverage component is flowed through the second inlet to the chamber for mixing of the components in the chamber and exit of the mixture from the chamber through the chamber outlet. The pressure of the second beverage component in the second inlet is sensed upstream from the chamber and the flow of at least one of the first and second beverage components to the chamber is controlled in accordance with the sensed pressure to deliver to the mixing chamber a predetermined ratio of the first and second beverage components.

Abstract: The present invention comprises an ice harvest system for use in an ice maker. The ice maker herein includes a refrigeration system for cooling of an evaporator. Ice is formed thereon as water is pumped by a re-circulating pump to flow from a water distribution tube over the evaporator surface. Water that is not immediately frozen thereon flows into a water pan positioned there below. A pressure fitting is positioned in the pan at the bottom thereof and connected to a pneumatic tube. The pneumatic tube is connected to a pressure sensor located on a control board at a position remote from the water pan. Pressure is communicated through the tube to the pressure sensor as a function of the depth of the water in the pan. This pressure is converted by a microprocessor of the control board for interpretation as a water level in the pan. As the water level in the tray lowers due to the formation of ice, the pressure transmitted to the pressure sensor reduces from a predetermined high or full water level.

Abstract: The ice maker herein works in the conventional manner wherein a refrigeration system provides for cooling of the evaporator. Water is first circulated over the evaporator as the evaporator is cooled. A temperature sensor is located in a water recirculating system and a microprocessor monitors the temperture of the circulating water. Once a predetermined non-freezing temperature is reached, for example 40 degrees Fahrenheit, water circulation is stopped. However, the compressor continues to run and cool the evaporator for a predetermined period of time to a desired lower temperature. The pump is then turned on and water again circulated over the evaporator initiating the ice making cycle. This process insures that ice adheres to the evaporator and does not prematurely slough off and/or result in the formation of slush.
