Abstract: A method is provided for transferring a charged particulate image such as a xerographic image across gaps between electrodes where the electrode spacing is much greater than heretofore employed. Thus, envelopes containing bulky objects such as keys, novelties and the like, can be addressed by xerographically forming a particulate image in the conventional manner and transferring it in accordance with the invention. In accordance with the invention, a charged particulate image is deposited on a non-absorbent dielectric transfer sheet and transferred to an absorbent receiver sheet by placing the transfer sheet and receiver sheet between a pair of electrodes having a potential difference sufficient to transfer the charged particulate image, one of the electrodes being a pointed electrode positioned behind the transfer sheet having an emitting angle of between 0.degree. and about 90.degree. so as to provide high fields at the emitting end of said electrode and the second electrode being a blunt electrode positioned behind the receiver sheet having an emitting angle of between about 90.degree. and 180.degree. so as to provide low fields at the emitting surface of said electrode.

Abstract: An electrostatic powder painting apparatus has a cyclone structure for directing powder paint toward a surface which is to be painted. The cyclone structure includes a feed cylinder having an open outlet through which the powder paint is delivered toward the surface to be painted, this feed cylinder having an outlet which is spaced from the outlet and which is adapted to receive air and powder paint suspended therein. The air is given a whirling motion within the feed cylinder so that the powder paint suspended in the air is centrifugally advanced along the inner surface of the feed cylinder from the inlet toward the outlet thereof, a conduit communicating with the inlet to supply thereto air with powder paint suspended therein. An exhaust cylinder, whose diameter is smaller than the feed cylinder, communicates coaxially with the feed cylinder to discharge air from the interior thereof. An air supply communicates with the conduit while between the air supply and the inlet of the feed cylinder there is a powder paint supply from which powder paint is delivered to the conduit to be conveyed with the air flowing therethrough to the inlet of the feed cylinder. The part of the above conduit extending from the powder paint supply to the inlet of the feed cylinder and the feed cylinder itself provide for the air and powder a path of flow extending along the interior of the conduit from the powder paint supply through the inlet into the feed cylinder and along the feed cylinder through and somewhat beyond the outlet thereof. Situated along this path of flow is a corona discharge electrode structure for electrostatically charging the powder paint with unipolar ions so as to drive the charged powder paint electrostatically toward the surface which is to be painted.

Abstract: A process for preparing a waterless printing master having a minimum background ink reflection density comprises coating a master substrate with an ink releasing block copolymer comprising elastomeric ink releasing siloxane blocks and isothermally crystallizable thermoplastic organic blocks. Thereafter, the thermoplastic blocks are isothermally crystallized and the siloxane blocks are preferably cross-linked. The printing master is imaged by depositing ink accepting particulate imaging material on the copolymer coating and heating and cooling the thermoplastic blocks to bond the particulate imaging material thereto.

Abstract: A power grid for a fluidized bed for electrostatically depositing a powdered plastic coating material from the bed onto an elongated metal substrate moving in a path of travel above the upper surface of the bed on a substantially horizontal pass line. The power grid includes two co-planar wire mesh elements positioned beneath the surface of the bed, the elements having opposed edges in parallel spaced relationship and defining a gap therebetween beneath the pass line. The edges are upturned to form a plurality of electrode segments, the tips of the electrode segments being substantially coincident with the upper surface of the bed when energized. In operation the electrode segments form a row of localized corona discharges to either side of the passing substrate to effect electrostatic deposition of a thin uniform film coating of the powdered material thereon.

Abstract: In an electrostatic powder coating method for coating a plate with electrostatic coating powder after or before the plate is provided with marking lines by electrophotographic print marking process, areas which are preferred to be free from the coating are not applied with the coating powder. After the coating powder is uniformly scattered on the plate, the powder is selectively removed to form a pattern shaped coating on the plate to form a non-coat area around the marking lines. In order to selectively remove the powder from the surface of the plate, a powder removing device which is controlled by a non-coating signal is used. The non-coating signal is given by a non-coating information output device. The non-coating information is recorded on an original which carries marking information for the electrophotographic print marking process. The marking information is recorded in one color and the non-coating information is recorded in another color on the original so that the marking information and the non-coating information may be detected independently of each other.

Abstract: In a method for coating the inside of a receptacle, fluid flow is controlled by a valve that has a torpedo shaped valving member in the middle of an enlarged passageway. The valving member contains an elastomeric sleeve that expands outwardly from a hinged area when compressed to form a line seal with the passageway. The valve is in the form of a multiple valve -- feeding, bypass and venting valving units all in one dielectric casting. Said casting is unitary with flange means operative to seal and mask said inside with respect to the external surface of the receptacle while the vent and coating material discharge means is functionally associated with said inside.

Abstract: A method for powder coating of articles with an organic polymeric material. Articles to be coated, preferably glass containers, are transported by a first conveying mechanism through a pre-heat oven wherein their temperature is raised to a level above ambient temperature. The preheated containers are then transferred to chucks of a second conveying mechanism which carry the containers through a powder spray apparatus wherein the organic polymeric material is applied to the container. The chucks of the second conveying mechanism are cool and any oversprayed material will not adhere thereto. After spraying, the containers are again heated to cure the sprayed-on powder coating to form a filmlike layer on the container. The containers are then cooled below the softening point of the organic polymeric material and released from the second conveying mechanism for further handling.

Abstract: A porous, electrical insulating adhesive substrate is made by (A) electrostatically coating a flexible sheet material with heat reactive adhesive resin particles, having an average particle size of between about 1 micron to 2,000 microns, the adhesive particles are applied in a predetermined pattern on the sheet covering from about 10 percent to 90 percent of the sheet material area, the area between the resin pattern not being patterned and then (B) heating the patterened coated sheet material between about 65.degree.C to 250.degree.C, forming a discontinuous, 0.25 mil to 25 mil (0.006 mm to 0.635 mm) thick, dry coating pattern of heat reactive adhesive particles bonded to the sheet material, said heat reactive adhesive coating covering from about 10 percent to 90 percent of the sheet material area; the patterned coated sheet may then be inserted as an oil permeable layer insulation between high voltage windings and low voltage windings and between layers of high and low voltage windings in a wound coil assembly, after which the assembly can be heated at a temperature and for a time effective to securely bond the winding layers together, and thus provide a porous, oil permeable, bonded transformer coil assembly.
