Abstract: An installation particularly suited to use in the automobile industry for electrostatic application of conductive coating product is partly at a high-tension voltage and partly grounded, these parts being separated by at least one temporary insulating device. The electrostatic sprayer is fed from a first storage tank insulated from ground and the latter is filled in a very short time period with coating product previously stored in a grounded second storage tank, through a temporary insulating device.

Abstract: In an electrostatic spray coating apparatus (10), liquid coating material is applied to a workpart inside of a spray booth (12). Alternating flows of liquid coating material, liquid solvent and air are conducted through various internal flow passages in a conduit (14) inside the spray booth. An electronic differentiator (24) is positioned adjacent a predetermined location along the conduit (14) and energized from an electrical source disposed outside of the spray booth (12) to differentiate between liquid and gas in the internal flow passage for nonintrusively detecting when the head of liquid flow reaches the predetermined location along the internal flow passage. This is accomplished by an electromagnetic field extending into the flow passage and sensing the changes in the electromagnetic field resulting from dielectric differences between liquid and gas in the flow passage.

Abstract: An apparatus for and method of coating an article by the use of electro-static attraction of ionized particles which are subsequently cured. The apparatus includes a first foraminous conveyor for carrying the article through a powder coating zone and a second conveyor for carrying the article through a curing zone. The surface of the article which rests on the foraminous conveyor is cleaned of particles as the article is transferred from the first foraminous conveyor to the second conveyor. The first foraminous conveyor is also cleaned of particles after the article has been transferred. After the articles have been cured to form a coating on the article, the article is put through the coating system again except that the article is supported on the conveyor so that the surface which was not coated in the first pass through the system is out of contact with the conveyor. During the subsequent pass of the article through the coating zone, the uncoated surface of the article is then covered with powder which is subsequently cured during the second pass of the article through the curing zone. The second coating step for the article may be accomplished by passing the article through the same apparatus as for the first step or by passing the article through a second identical apparatus.

Abstract: A coating method and apparatus allows coating of a paper substrate from any point from the first de-watering stage to a fully dried stage. The method includes the making of a fog from a coating slurry, and directing the fog to a nozzle that does not physically contact the substrate. An air current normally carries the fog; but, electrostatic charges can be applied to the substrate and the fog to cause the fog to be attracted and adhere to the substrate. Vacuum chambers contiguous with the nozzle pick up excess fog and deliver the excess to a separator for recycling.

Abstract: An electrostatic spray coating method where an electrical field is generated between a spray gun and an object for electrostatically attracting the paint to the object for coating the same. A positive or negative voltage is preliminarily applied to the object through a clamping device disposed on a floor face of a spray booth with the spraying system for spraying the paint from the spray gun being electrically grounded while the object is maintained electrically insulated by suspending it from a hanger rod with an insulator of a hanger conveyor type installed in the spray booth.
