Abstract: Apparatus and method for electrostatically charging a stream of atomized paint particles discharged from a spray gun. An emitter electrode is positioned in spaced relation to the end of the spray gun to establish a corona discharge from the electrode tip to a conductive portion of the gun end so that the direction of the discharge is opposite to the direction of flow of the particle stream. The apparatus may comprise an attachment unit for converting conventional spray guns to electrostatic spray guns, including a dielectric flow path-defining member downstream of the spray gun.

Abstract: Electrostatic precipitating apparatus in which particles entrained in a gas stream are charged in an ionization zone established between one or more ionizer electrodes and a movable attractor electrode and collected, by reaction with a transverse precipitation field, in an adjacent downstream zone including a movable dielectric collection surface. The dielectric collection surface may be carried by the same conductive member constituting the attractor electrode. Electric fields that are non-attractive to the charged particles, and that have components directed against gas flow, are established in the vicinity of the ionization zone-collection zone interface, thus increasing collection efficiency by retarding downstream movement of the particles, including turbulence in the gas stream, and creating non-linear precipitation field conditions. A series of such collection zones or of additional ionization zones and associated collection zones may be spaced along the gas stream to further enhance precipitation efficiency and to reduce re-entrainment of particles in the gas stream. The ionizer and attractor electrodes and the dielectric collection surfaces are movable to a cleaning zone remote from the gas stream where collected particles are neutralized and removed.

Abstract: An apparatus and method for reproducing an image on a dielectric sheet, such as paper or the like, comprising the use of an electrogasdynamic generator as a spray gun for producing a space charge cloud of ionized ink in the vicinity of one side of the dielectric sheet whose other side has been provided with an electrostatic charge image produced through the use of a conventional xerographic plate and process, whereby an improved quality ink image is produced on the sheet by virtue of the tendency of electrogasdynamically produced particles to achieve a uniform charge distribution on the dielectric surface. Undesirable fringing effects are avoided and the process is speeded up over the conventional xerographic process by reducing the number of mechanical operations required, such as, eliminating the need for cleaning toner from the xerographic plate. The method may be adapted to produce either negative or positive images and for use with high-speed printing systems.

Abstract: Systems for effecting a conversion between the energies of a gas and electrical energy and employing at least two electrogasdynamic (EGD) devices each having ionizing electrodes and an output electrode for connection to an external circuit. Each EGD device is connected in series with the external circuit and the amount of electrical energy available for transfer to or from the circuit from each converter is periodically varied so that an alternating current potential is maintained at the output electrode during operation. Periodic variation is achieved by varying an electrical ionizing source for the ionizing electrodes, or by varying gas flow through each EGD device.

Abstract: Electrogasdynamic systems in which a plurality of slender gas flow channels carry electrical charges to a downstream charge collector. Each flow channel is of elongate cross section, and the elongate dimension thereof may progressively increase from one end of the channel to the other. Electrical charges are injected into the flow by a corona discharge established in the flow between attractor and corona discharge electrodes extending laterally across the flow in the direction of elongation of the channel cross section and located preferably at the channel side. Adjacent channels are defined by spaced dielectric plates or by spaced rows of conductive wires mutually spaced in the direction of flow and connected externally to an electrical biasing or current-carrying circuit.

Abstract: Methods and apparatus for applying coating materials to articles, using electrogasdynamic apparatus providing a flow channel having a dielectric boundary which has a length-/width ratio of greater than 2.5. Gas containing particulate coating material is ionized to create an electrical discharge field for imparting an electrical charge to the particles prior to passage through the dielectrically bounded flow path and thereby creating a high space charge potential. In special applications, a freeradical forming monomer gas or a fusible particle substance is carried in an inert gas into the electrical discharge field and through the flow channel toward the article to be coated. In any case, the charged particles are subjected to an axial charge repelling field (due to space charge effects) in the flow channel to raise the electrical potential of the particles, and thereby the potential gradient between the particles and the workpiece.

Abstract: An electrostatic precipitator in which particles entrained in the gas stream are charged electrically by a corona discharge field established in opposition to the gas stream between a plurality of emitter electrodes and a screen attractor electrode upstream of an surrounding the emitter electrodes, inducing turbulence in the stream. The velocity at which the particles pass through the charging field is increased by a dielectric converging-diverging nozzle located across the gas stream closely adjacent the particle charging field to retard migration of the charged particles to the screen attractor. The charged particles are collected downstream of the discharge field on an electrically charged moving dielectric member by which an electric precipitation field terminating at a passive reference electrode is maintained across the gas steam. Charges and charged particles are held on the collection surface of the dielectric member by an electric field created between that surface and a conductive member adjacent the opposite surface of the dielectric member. At a location isolated from the gas stream, the collected particles are removed from the collecting surface.
