ABSTRACT:
An apparatus for charging droplets of a volatile liquid and for directing the charged droplets against an oppositely-charged member. The apparatus comprises a source of a mist of uniform fine droplets of a volatile liquid and a droplet-charging zone associated with said source for applying a charge to the droplets in the mist. The droplet-charging zone comprises a source of ionized air ions for imparting the charge and a predetermined velocity to the droplets. A discharge conduit is provided having a discharge nozzle for directing the charged droplets against the surface of a member for attraction and deposit onto areas thereof charged to an opposite polarity. Preferably, the droplet-charging zone is associated with an air ionization zone comprising a source of air, a means for ionizing the air, and a means for directing the ionized air at a predetermined velocity into the droplet-charging zone to apply the charge to the droplets. Also, preferably the droplet-charging zone comprises oppositely-charged electrodes providing an alternating current therebetween for vibrating the air ions into contact with the droplets to assist the imparting of the charge of the air ions to the droplets.
