Abstract: This invention relates to a process and a device for producing an even and homogenous coating of liquids or powders on small free-falling objects that are not earthed. The process and the device according to the invention are primarily intended for surface coating of medicinal products and foodstuffs. According to the invention, the non-earthed objects are positively or negatively charged in a suitable manner or not at all and are then caused to fall freely and individually through a substantially cylindrically-shaped zone (2), mainly along its central axis, where the coating substance, having first, in a suitable manner, been charged with a charge of opposite polarity to that of the objects or if these are not charged, with a positive or negative charge, is sprayed onto the particles by means of at least one or preferably at least two spray nozzles (3) which are placed peripherally around the zone (2) and directed mainly towards the central axis thereof, whereby the coating substance is attracted to the object because of the potential difference between them, and an even, homogenous surface coating is obtained.

Abstract: A mist generator produces a mist from a liquid precursor. The mist is charged and accelerated by a pair of charged electrodes in an acceleration chamber. The mist passes through a conduit charged to the same polarity of the mist particles, to a deposition chamber where they are deposited on a substrate having the opposite polarity as the particles. Infrared lamps heat the mist particles in the acceleration chamber to a temperature below the temperature at which the compounds and solvent in the liquid precursor decompose. In one embodiment the deposition chamber is tubular and a plurality of substrates are held within the chamber in a position substantially perpendicular to the direction of mist flow in the chamber. A heater and an electrical field generator in the tube add sufficient energy to the mist as it passes through the tube to provide uniform deposition of the mist on the plurality of substrates.

Abstract: Cup lubricating process and apparatus in which cup-shaped can bodies are controllably conveyed in spaced relationship to each other through a lubrication application chamber. Lubricant is atomized to particle sizes permitting them to be gas borne and introduced into such chamber from a plurality of locations about the travel path for can bodies. Apertures in the bottom wall of such chamber direct lubricant particles directly into the open ends of such can bodies for flow impingement deposition on internal surfaces thereof. Provision is made for augmenting surface deposition by electrically charging at least a portion of the gas-borne lubricant particles in such chamber and electrically grounding can bodies individually during passage through such chamber. Endless loop conveyor means are provided with adjustable features enabling a travel path to be adapted to differing dimension can bodies.

Abstract: An electrostatic coating system for applying very thin coating to a substrate in air at atmospheric pressure comprises a plurality of spaced capillary needles positioned in at least two rows and fed with coating liquid via a manifold. The needles are disposed concentric within holes in an extractor plate, a potential is developed between the capillary needles and the extractor plate affording a reduction of the liquid to a mist of highly charged droplets drawn to the substrate by a second electrical field. Insulative layers on the extractor plate provide increased droplet control.

Abstract: In the electrostatic application of a coating material on to a product to be coated, the product leaves a supply hopper over a tube enlargement and falls freely in a chamber in the form of a tubular curtain. The tubular curtain falls around a central, elongate, vertical corona discharge electrode so that a high voltage electrostatic charge of one sign is applied to the falling curtain of the product. Coating material is sprayed on to the product by atomizers in the chamber. A high voltage electrostatic charge of opposite sign is applied to the coating material by way of the atomizers.

Abstract: Material comprising particulate matter is atomized and coated on a surface of an object by delivering the material to a surface of a spinning atomizer from a non-rotating delivery means preferably situated within the volume defined by the atomizer. The material is atomized by being thrust from the atomizer surface and at least a portion of the atomized material impacts the surface being coated. The method is particularly applicable to coating surfaces wherein abrasive material is atomized, since a seal between the non-rotating delivery means and atomizer is not needed, and wherein space limitations are imposed on the configuration of the atomizer. Further, a potential difference may be established between the atomized material and surface to be coated whereby an axial flow of material from the surface of the atomizer may be effected.

Abstract: This invention relates to a strippable coating process and a coating composition therefor comprising (1) a latex, (2) a coagulant for said latex and (3) a debonding agent consisting essentially of a substantially non-volatile additive which is adhesive to at least one of either the coated substrate or coagulated coating, more soluble in water than in the coagulated latex polymer component and having a solubility parameter at least 2(calories/cc).sup.1/2 higher than the coagulated latex polymer component.The protective coating is formed by impinging a stream of a latex and a stream of a coagulant, the two streams being oppositely charged, onto a substrate. After drying an external debonding agent is applied between the coating and the substrate and thereafter the coating is stripped from the substrate.
