A method for automatically filling beverage containers from a pair of adjacent beverage dispensing valves including transmitting ultrasonic energy down from each valve and receiving reflected ultrasonic energy to detect a container, filling the detected container, and operating each valve separated

A method for automatically filling beverage containers from a pair of adjacent beverage dispensing valves including transmitting ultrasonic energy down from each valve and receiving reflected ultrasonic energy to detect a container, filling the detected container, and operating each valve separated in time by synchronizing their operation to different half cycles of an a.c. power supply, to prevent interference therebetween.

A method for automatically filling beverage containers comprising the steps of: (a) operating each of a pair of adjacent valve assembles by: (1) transmitting ultrasonic energy down from each valve assembly toward a container supporting surface located below a beverage dispensing nozzle of each valve

A method for automatically filling beverage containers comprising the steps of: (a) operating each of a pair of adjacent valve assembles by: (1) transmitting ultrasonic energy down from each valve assembly toward a container supporting surface located below a beverage dispensing nozzle of each valve assembly from an ultrasonic transmitter on each valve assembly; (2) receiving ultrasonic energy reflected back up from the direction of said surface with an ultrasonic receiver on each valve assembly and separate from and spaced apart from said transmitter and generating said corresponding signals; (3) detecting the presence of a container when placed on said surface and below said nozzle; and (4) controlling the filling of said container with beverage from said nozzle; and (b) operating said adjacent valve assemblies separated in time by synchronizing their operation to different half cycles of an a.c. power supply, to prevent interference therebetween.
