Abstract: An agricultural chemical sprayer is disclosed using special pre-coded machine-readable chemical containers which, when attached for use, become an integral part of an automatic spray control system. The pre-coded data derived from a given container effectively prevents unauthorized and unsafe container refilling operations and, at the same time, automatically provides optimum control over the spray application rate (pump operation and/or electrostatic voltage), prevents mixing of incompatible spray solutions, prescribes proper spray system flushing procedures, and at all times after filling maintains an irreversible account of the available liquid remaining in the container. Provisions are made for monitoring the condition and/or operation of each spray nozzle and special connectors are provided for effecting optimum liquid and electrical circuit connections in such a system. A distributed logic microprocessor-based electronic control system, a modular nozzle design incorporating a customized I/O integrated circuit and a special container design including a customized PROM integrated circuit are provided in the preferred embodiment.

Abstract: An apparatus is provided for producing a spray of atomized and electrostatically charged particles of liquid to remove oppositely charged pollutants from the atmosphere. The apparatus is particularly suited for use in a potentially explosive atmosphere. The apparatus includes a nozzle which receives liquid and compressed air and produces a high pressure spray of atomized liquid particles. A ring electrode coaxially surrounds the spray near the nozzle. The electrode is chargeable to a high electrostatic potential relative to the nozzle, whereby the liquid particles of the spray are inductively charged by passing the ring. The electrode is fully encased in a ring of insulating material. A grounded metal housing surrounds the ring of insulating material on all sides except the radially interior side thereof. The metal housing and ring of insulating material are coated on all exposed surfaces by a dip coating of insulating material.

Abstract: Electrostatic spraying apparatus employs a concealed electrode at a low potential (relative to that used in conventional apparatus) to form an induced charge on a thin layer of liquid. Subsequent mechanical atomization of the charged layer produces a spray of charged droplets. The thin layer is produced by centrifugally spreading an inlet flow and atomization may also be achieved by rotation. An air flow is arranged to sweep the charged droplets out of the field of the electrode and a baffle, in which the electrode is embedded, is formed to control the direction of emergence of the spray from the nozzle.

Abstract: Disclosed is a low volume, space-charge controlled electrostatic spraying which is particularly suitable for use in agriculture but is applicable to industrial and other settings as well. A substance is sprayed through a relatively low voltage nozzle producing finely divided, electrostatically charged particles of the substance. The charged particles are liquid droplets or dust particles, and are about 50 microns or less in size. The space-charge density of the charged particles is monitored, and the deposition of particles on a calibration target is measured at different space-charge densities to establish an optimal space-charge density corresponding to optimum (e.g., maximum or most uniform) deposition. As the charged particles are subsequently directed to target objects, such as plants, the space-charge density is monitored and the spraying and/or charging systems are controlled to maintain the established optimal level which corresponds to optimal deposition.

Abstract: The electrostatic spray device includes a liquid sprayer including a nozzle that spouts a liquid; a voltage applicator that applies a voltage between the liquid sprayer and a heteropolar portion functioning as a pole opposite a pole of the liquid sprayer to generate an electrostatic force for causing the liquid to separate from a distal end of the nozzle in a charging state; and a stabilization electrode that maintains a stable spraying state of the liquid even when a pressure is applied to the liquid to supply the nozzle with the liquid. The stabilization electrode has an electric potential identical to an electric potential of the liquid sprayer, and is disposed near the nozzle such that a jet portion formed at a front of the nozzle by a linear extension of the liquid has a length longer than a length of the jet portion before the stabilization electrode is provided.
