Abstract: An atomized cloud of droplets having an electric charge is generated wherein different discrete parts of the cloud are formed from different liquids. The discrete part of the cloud which has an active ingredient, such as a chemical insecticide or herbicide, is contained such as by enveloping it or directing it in a particular direction by a further discrete part of the cloud that includes an inert liquid such as water. The spraying apparatus comprises a plurality of nozzles positioned in a high velocity air stream to disperse liquid and generate an atomized cloud of the liquid. The nozzles are grouped into at least two sets, each set being arranged and positioned to generate a discrete part of the cloud. An electric charge is placed on the droplets as they are emitted. Each set of nozzles further include a liquid reservoir connected to the nozzles. Each reservoir is to contain a different liquid whether it be an inert liquid or different concentrations of an active liquid.

Abstract: A spraying apparatus to deliver inductively charged spray, for example to crops. The apparatus includes a spray head and electrodes to apply a potential difference in the region of the spray head to charge spray. An aspirating means is arranged to remove liquid deposited on an electrode to reduce interference with the charging process. When the spray liquid is to be at high potential in the apparatus a long high resistivity supply tube may be provided. The aspirating means may be operated by spray liquid bled from a pressurized supply spray liquid.

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: A dual-liquid spray apparatus for dispensing concurrently two different liquids, such as droplets, having a spray nozzle assembly with two nozzles, each having a nozzle axis for dispersing a spray pattern of a liquid along the nozzle axis. In some embodiments, the dual-liquid spray apparatus can dispense the two liquids concurrently and simultaneously, where the nozzle axis of the first nozzle diverges at a diverging angle from the nozzle axis of the second nozzle. In some embodiments, the dual-liquid spray apparatus can dispense the two liquids concurrently and alternatingly, where a first supply means provides a series of pulses of the first liquid composition to the first nozzle, and a second supply means provides a series of pulses of the second liquid composition to the second nozzle alternatingly and non-overlapping with the pulses of the first liquid composition.

Abstract: An electrostatic spray nozzle assembly is described that includes an induction ring and a fluid tip. The induction ring generates an electrical field for inducing an electrical charge on droplets of a feedstock liquid from the fluid tip that pass through an opening of the induction ring. The induction ring is electrically coupled to an electrical induction field source via a first conductive path provided by conductive surfaces of: a nozzle head holding the induction ring, and a purge gas tube holding the nozzle head. Feedstock flowing through the fluid tip is electrically coupled to a charge carrier source via a second conductive path provided by at least a conductive surface of a fluid tube coupled to the fluid tip. The first conductive path and the second conductive path are electrically isolated by an insulating barrier.
