Abstract: Apparatus and method for electrostatically charging a stream of atomized paint particles discharged from a spray gun. An emitter electrode is positioned in spaced relation to the end of the spray gun to establish a corona discharge from the electrode tip to a conductive portion of the gun end so that the direction of the discharge is opposite to the direction of flow of the particle stream. The apparatus may comprise an attachment unit for converting conventional spray guns to electrostatic spray guns, including a dielectric flow path-defining member downstream of the spray gun.

Abstract: An aspirator system particularly for use with an electrogasdynamic generator wherein a fine aerosol is regulatably produced using a dual atomizing of the seeding medium. The seeding medium, which is contained in a suitable reservoir, is passed through a chamber prior to introduction into the main aerating fluid stream, and is preatomized in the chamber by a secondary fluid flow which may be tapped from the main aerating fluid stream. The secondary fluid enters the seeding medium reservoir to contribute to the pressure head causing medium flow and is introduced in the chamber in the form of a series of jets through holes in the chamber wall to preatomize the seeding medium therein. Control of the pressure and rate of secondary fluid flow permits fine control of the amount of seeding medium introduced into the main aerating flow and the degree of atomization achieved by the entire system.
