Abstract
Abstract A fluid distribution system is shown which includes a plurality of electrically actuated valves. Each valve is associated with a selectively activated switching device responsive to a particular control signal of preselected frequency. A band-pass filter is connected between each switching device and a source of control signals having differing frequencies and preselected durations for activating the switching devices. The source of control signals may be a source of prerecorded signals, such as a replacable cassette, or a preprogrammed oscillator arrangement.
