Abstract
The sequence controller disclosed is a microprocessor based unit having a user programmable sequence of electronic pulses for the control or synchronization of valves, relays, solenoids and timers. The controller is connected to spray nozzles adapted for projecting atomized droplets of liquid between charged electrodes in a timed sequence to cause the charged droplets to be attracted to and impinge against partial areas of a grounded surface to form a continuous substantially uniform film of liquid on the surface.
