Abstract: Apparatus for removing dust from a gas stream comprises a duct with an inlet at its top, a hopper spaced beneath the inlet, and a lateral outlet at a level between inlet and hopper. Gas flowing from inlet to outlet must traverse a vertically extending filter comprising elongated parallel electrodes laterally spaced from one another at small intervals. Each electrode is connected with a terminal of an alternating voltage source different from that with which its adjacent electrodes are connected. The constantly varying alternating electric fields at the filter repel particles so that they fall into the hopper.

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 improved powder material processing apparatus is described herein, in which a plurality of wire-shaped electrodes are disposed within an imaginary plane at an equal interval and in parallel to each other. An insulator layer is interposed between the adjacent wire-shaped electrodes to prevent spark discharge from being generated by an A.C. high voltage applied between the adjacent wire-shaped electrodes. A silent discharge region is established between said adjacent wire-shaped electrodes, and positive and negative charges are separately given to the particles forming said powder material by making uncharged powder material pass through said silent discharge region, resulting in formation of powder material consisting of substantially equal numbers of positively charged particles and negatively charged particles, whereby control characteristics of the processed powder material can be greatly improved and the above-mentioned charging process can be effected continuously at a high efficiency.

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.

Abstract: In a pair of surface-shaped silent discharge electrodes opposed to each other and separated by a predetermined space therebetween, phases of alternating voltages are applied to said respective silent discharge electrodes shifted in phase with respect to each other so that a silent discharge may arise alternately on either one of the electrode surfaces. A second alternating voltage is applied between the silent discharge electrodes and is alternatingly varied at a fundamented frequency twice as high as the frequency of the first alternating voltages applied to said surface-shaped silent discharge electrodes and is not inverted in polarity during the period when the silent discharge exists on either one of the electrode surfaces. Powder particles are passed through the space which separates the pair of surface-shaped silent discharge electrodes and charged in either positive or negative polarity continuously at a high efficiency.

Abstract: An electrostatic dispensing system for dispensing flowable liquid material onto a moving substrate. The electrostatic dispensing system includes multiple liquid dispensers that are aligned along a common axis and supported in spaced, non-contacting relationship on one side of the moving substrate. Each of the liquid dispensers includes a valve to control the flow of fluid through the dispenser. An electrostatic field generator is supported in spaced, non-contacting relationship on the opposite side of the moving substrate to generate an electrostatic field through the moving substrate. The electrostatic field operates to attract flowable liquid material from dispensing outlets associated with the multiple liquid dispensers as a series of spaced, continuous streams or beads which intersect a surface of the moving substrate facing the liquid dispensers. The beads of flowable material are deposited on the surface of the moving substrate in a series of uniform, continuous beads which are formed generally parallel to a direction of travel of the moving substrate. Methods of electrostatically dispensing flowable material onto a moving substrate are also disclosed.
