Abstract: A self adjusting power supply for induction charging electrodes used in electrostatic spray coating apparatus is disclosed. A first resistance of high ohmic value is connected in series between a source of high direct current voltage and the induction charging electrode, while a second resistance is connected between the source of voltage and a ground reference point. The first resistance acts as a voltage divider with the spacial impedance which exists between the charging electrodes and ground in the spray nozzle of the spray coating apparatus, and serves to regulate the charging voltage and to compensate for variations in the conductivity of the material being sprayed. If the value of the spacial impedance should decrease for any reason, the increased current flow therethrough produces an increase in the voltage drop across the first resistance, thereby reducing and thus regulating the potential at the charging electrodes and serving to prevent corona and arcing within the spray gun. The ohmic value of the first resistance, which is in the range of 1-50 gigohms, is sufficiently high to prevent any substantial current flow from the charging electrode, thereby reducing the shock hazard of the spray gun, and also to prevent any significant changes in the current flow due to changes in the conductivity of the spray material. The second resistance serves as a bleeder for the charges on the spray gun and the induction charging electrode when the gun is turned off.

Abstract: A system for electrostatic spraying of liquids, such as agricultural pesticides, paints and other liquids, which relies on a novel spray nozzle that combines pneumatic atomization and electrostatic induction charging to provide a stream of electrostatically charged fine droplets. The nozzle uses a low voltage power supply, e.g. a 12 volt battery, electronically raises the voltage to a level in the range of several hundred to several thousand volts, and applies the high voltage to an annular induction electrode which is embedded in the spray nozzle. The high voltage components are inside the nozzle, which is made of an electrically insulating material, to minimize the danger of shock and the possibility of mechanical damage to the high voltage components. The spray nozzle operates at a relatively low voltage and at a low input power, but provides a droplet stream at a high droplet charging level, for effective and uniform deposition of the sprayed liquid onto the target.

Abstract: An electrostatic spray charging device wherein means in a passageway or a barrel of such device directs a jet of air between a charged electrode in the passageway and a plurality of liquid termini at an orifice within the passageway in a manner as to direct particles atomized from the plurality of termini generally away from the charged electrode and the side walls of the passageway. The charged electrode and the liquid termini are adapted to be connected to an electrical source thereby creating a potential difference between the charged electrode and the liquid termini. The potential difference therebetween provides a high intensity electric field at the liquid termini whereby particles atomized from the individual liquid termini carry a high charge-to-mass ratio. Preferably, the jet of air passing between the charged electrode and the liquid termini assists in atomizing liquid particles from the liquid termini. The charged liquid particles are attracted to and deposited upon the surface of an object or article at a particle attracting potential.
