Abstract: Improved methods and apparatus for charging atomized coating materials and maintaining an electrostatic depositing field in the electrostatic deposition of coating materials. Improved charging is effected by the selectively directed passage of corona discharge current from a primary source thereof through emitted coating material intermediate its point of emission and its locus of atomization to an electrically floating electrode element whose collection potential is maintained by a corona discharge emanating from an exposed end thereof.

Abstract: A pneumatically assisted hydraulic atomizing apparatus for paint or other liquids. The spraying apparatus includes an atomizing head assembly which has a selectively shaped orifice for transforming coating liquid such as paint, into a high speed expanding coherent flat and fan shaped film of such liquid that inherently developes unstable wavelike characteristics leading to the atomization of the emitted liquid at the front edge of the film in combination with means for directing gaseous jets into impinging relation over substantially the full transverse extent of the coherent fan shaped film to decrease the thickness thereof and accelerate the atomization whereby the fluid emission velocity for a predetermined degree of atomization can be substantially reduced.
