Abstract: A device for electrostatically charging and dispensing a high resistivity cutting lubricant to a workpiece includes a source of high resistivity cutting lubricant and a capillary tube having an entrant end in fluid communication with the high resistivity cutting lubricant and a tapered discharge end forming a sharp point. A high voltage power supply is used for generating a high voltage of less than 5,000 volts d.c. The power supply has a positive terminal and a negative terminal. A high voltage electrode has its one end connected to the positive terminal of the power supply and has its other end operatively coupled to the discharge end of the capillary tube. A nearby grounded electrode is disposed in a spaced-apart relationship from the discharge end of the capillary tube so as to create a high electric field therebetween for electrostatically charging the lubricant. The lubricant is atomized and projected in the form of a steady and controlled stream of charged particles away from the discharge end of the capillary tube to within the vicinity of or all the way to the workpiece before the stream of charged particles bursts into an aerosol cloud of charged droplets for dispensing them onto the workpiece.

Abstract: An adapter for converting spray guns to electrostatic or induction charging includes a housing mountable on a spray gun. A high voltage power source is contained in the housing and is connected to an electrode assembly mounted on the front of the housing. The electrode assembly includes four electrodes which extend in front of the spray gun nozzle and air cap and are spaced symmetrically around the spray axis. The nozzle is electrically grounded, while the electrodes carry a voltage in the range of 3-15 kV, to produce in the spray path from the nozzle an electrostatic field which produces electrical charges on the sprayed particles. When conductive liquids are sprayed, the particles are charged by induction at relatively low electrostatic field gradients, while nonconductive liquids require high electrostatic field gradients which produce corona effects. These corona effects are enhanced by the provision of a corona needle mounted on the nozzle at the spray axis.

Abstract: An apparatus for spraying liquids from a vehicle, suitably an aircraft or other airborne vehicle. The apparatus includes at least two sprayheads, each having adjacent thereto an associated electrode or an associated electrically conducting or semiconducting part of the vehicle. A generator applies potentials to the sprayheads and to the electrodes or conducting or semiconducting parts of the vehicle so that an intense electrical field is developed between the liquid which emerges from each sprayhead and the adjacent electrode or part. The intensity of each field is sufficient to atomise the emerging liquid. The polarities of the applied potentials are such that liquid emerging from one sprayhead is charged positively while liquid emerging from the other sprayhead is charged negatively. Connections to the generator are such that electrical current flows from a target to the generator via spraying liquid and one of the sprayheads and then back to the target via the generator, the other sprayhead and liquid emerging from that other sprayhead.

Abstract: A nozzle for spraying apparatus to distribute crop treatment liquid. The nozzle is of general ogee shape with a base and an upper wall spaced from the base and connected to it by side walls. The upper wall extends from the apex of the base partially along the base to terminate in a trailing edge. The nozzle is placed in a high velocity air stream and liquid introduced between the base and upper wall. The high velocity airstream atomizes the liquid and distributes it in the surrounding environment. The nozzle is particularly useful in electrostatic spraying apparatus and may be made of plastics material to inhibit induction of electrostatic charge on the nozzle.

The case is molded into a suitable shape and is attached to the front of the gun by means of screws, bolts, a bayonet type connection or other suitable fastening means, the power pack being provided with external contacts which serve to engage corresponding contacts on the spray gun to provide an electrical connection through the gun to the power source, which may be a battery pack carried by the operator, and to engage coresponding contacts on the inductive charging device for the spray gun. The power pack can form the forward barrel portion of the spray gun with the discharge channels extending through the center of the case, or can be incorporated into detachable accessories such as a gas shroud forming chamber mountable on the forward barrel portion.
