Abstract: Particulate material is fed onto a certrifuge constrained to rotate coaxially in the wide upper portion of a funnel-shaped receptacle of insulating material. Particles are centrifugally propelled toward the inner surface of the receptacle through a space at which there is a corona discharge that electrically charges them. Annular electrodes embedded in the receptacle wall at vertically spaced intervals are connected to terminals of an a.c. voltage source to produce a constantly varying electric field that repels charged particles from the wall. Particles are further charged in leaving the bottom outlet of the receptacle, to be electrostatically attracted to an article to be coated with them.

Abstract: Charged particles are concentrated and held in space by means of an unequal, alternating electric field and the resulting beam of particles is directed through a hole in a plate electrode to a target electrode. A gate electrode adjacent the plate electrode may be operated selectively to oppose and enable the passage of the concentrated beam of charged particles to the target.

Abstract: A tubular duct of insulating material has three elongated electrodes spirally wound along it on its outer surface, uniformly spaced from one another. The electrodes are connected with the terminals of an alternating current source having a voltage of the order of 5-10 KV to produce a wave-like electric field within the duct by which particles are repelled from the inner duct surface and repulsively propelled in one lengthwise direction along the duct.

Abstract: An insulating or semiconductive tube defines a path along which powder flows from a source to an article to be coated therewith. Electrodes that extend circumferentially and are equispaced axially are embedded in the tube wall and are so connected with terminals of an a.c. source that there is a constantly varying potential difference between axially adjacent electrodes, to produce a field that tends to repel powder from the tube wall. A corona discharge electrode, fixed at the outlet end of the tube, is connected with one terminal of a high tension d.c. source. The other d.c. terminal is grounded to the article to be coated.

Abstract: A booth in which electrically charged particulate material is sprayed onto a workpiece having an opposite charge, so that the particles are electrostatically attracted to the workpiece, has all of its walls that confront the workpiece made of electrical insulating material. A grid-like arrangement of parallel, spaced apart electrodes, insulated from each other, extends across the entire area of every wall, parallel to a surface of the wall and in intimate juxtaposition thereto. Each electrode is connected with one terminal of an alternating high voltage source, every electrode with a different terminal than each of the electrodes laterally adjacent to it, to produce a constantly varying field that electrodynamically repels particles from the wall.
