Process and apparatus for spraying liquid
First Claim
1. A process for spraying liquid at a target, which comprises atomising liquid by charging it electrostatically at a charged conductive surface, projecting the charged atomised liquid on a path toward the target and at least partially discharging the charged particles so formed with an ionic discharge induced by the particles as they pass an earthed electrode having a sharp or pointed edge sited adjacent said path and pointing away from said charged conductive surface.

Abstract
A process and apparatus for spraying liquid at a target, which comprises atomizing liquid by charging it electrostatically, projecting the charge atomized liquid on a path toward the target and at least partially discharging the charged particles so formed with an ionic discharge induced by the particles as they pass an earthed electrode having a sharp or pointed edge sited adjacent said path.

3. Spraying apparatus for use in spraying liquid toward a target which comprises:
- means for supplying liquid to an atomisation site;
means for charging the liquid at the site sufficiently to cause it to atomise into charged droplets and be projected on an outward path toward the target; and
means for at least partially discharging the charged droplets on said outward path toward the target, said means including an earthed electrode having a sharp or pointed edge or edges adjacent to and directed toward or along said path and away from the atomisation site. - View Dependent Claims (4, 5, 6, 7, 8)
