Abstract: An electrostatic spray nozzle including: a paint nozzle having a labial paint spout hole for spurting a paint under predetermined liquid pressure; an air nozzle having an air blow hole forwardly of the paint spout hole for blowing air streams toward the spurted paint to accelerate atomization of the paint; and a needle electrode located forward of the air spout hole and applied with a high voltage to charge the atomized particles of the paint to a predetermined potential. Atomization of the paint which is spurted from the paint spout hole is accelerated by pressurized air streams from the air spout hole, while preventing the tailing phenomenom. The atomized paint particles are charged by passage through an ionizing zone which is formed around the needle electrode, thereby promoting the efficiency of paint deposition and at the same time the efficiency of paint atomization by the electrostatic atomizing action.

Abstract: A method for supplying an electrically conductive, floating medium, e.g. paint, from a storage system (11) via a feed conduit to a consumption station (12) in which is incorporated an electrostatically chargeable distribution device (29), e.g. a paint spraying gun, for treatment, e.g. painting of treatment units, whereby the medium is supplied to an intermediate storage forming part of the feed conduit between the consumption station and the storage system, and which feed conduit is adapted to be interrupted electrically and physically between the storage system and the intermediate storage by means of an interruption unit. The purpose is to prevent the electrostatic charge in the spraying nozzle from being transferred to the storage system of the painting plant. This has been solved in that the medium is pumped from the storage system via a first feed conduit to a first closed valve part forming part of said interruption unit, the second valve part of which, which is connected to a second feed conduit, at interconnection thereof establishes a closed medium connection between the feed conduits, that the medium during the interconnection period of the valve parts is pumped to the intermediate storage, whereby the electrostatical charging is interrupted, and that after disconnection of the valve parts the medium is subjected to pressure in the intermediate storage and during electrostatical charging is supplied to the distribution device.

Abstract: A stream of carrier gas with powder particles is introduced at the feeding end (2) of a powder pipe (1) in the direction of arrow (3) for coating workpieces. The material of the coating powder, of the powder pipe (1) and of displacement bodies (21, 22) built in the latter have different dielectric constants. At a certain distance from the outlet end (5) is mounted a charging device (12) provided with boosting electrodes (15) projecting inwardly and connected through a protective resistance (15) to a high-voltage supply (17). A rear counter-electrode (7, 26, 27) comprises an earthed conductive body (7). The displacement bodies (21, 22) accelerate the flow of powder particles. The latter come repeatedly in contact with the inner surface (11) of the powder pipe (1) and the displacement bodies (21, 22), communicating negatively charged particles (10) to them, after charge separation, whereas the positively charged particles (4) remain attached to the powder particles. The concentration of negatively (10) and positively (4) charged particles at opposite ends (2, 5) of the pipe is increased through the electrostatic field acting between the boosting electrodes (13) and the counter-electrode (7, 26, 27). The coating powder is thus so highly charged that an outer electrostatic field between a spraying electrode and the workpiece can be dispensed with.

Abstract: Systeme de peinture par pulverisation electrodynamique ayant un pistolet de pulverisation (13) pour pulveriser la peinture vers une piece de travail (15) et une electrode (16) pour exercer une charge sur la peinture. Un generateur de forme d'ondes de haute tension (21) envoie une tension d'oscillation sur cette electrode (16) de telle sorte que des couronnes de resistances variables soient generees periodiquement et de maniere controlee. Cette tension d'oscillation augmente le spectre des charges sur les particules de peinture, ameliorant ainsi l'uniformite de la couche de peinture sur la piece de travail (15). De plus, les pertes de peinture sont reduites. Cette invention s'applique egalement a d'autres materiaux de recouvrement tels que des poudres.

Abstract: The purpose of the invention is to provide a method and the required apparatus to coat articles of any shape and size with a layer of protective coating in an effective, energy-efficient, safe and economical way, omitting the use of electrostatic generators and avoiding contamination of the environment and loss in materials. The coating agent contemplated is powdered plastic which is introduced into a structure (See Figure 3) which is in the form o fa main closed circuit loop (8) in which a blower (7) circulates air carrying coating agent until it has acquired substantial electrostatic charge, which can be increased by the addition in that loop of a section (13) of increasing diameter in the direction of the flow of powder. When the requisite electrostatic charge has been achieved, valves (17), (18), (26) and (27) are opened putting the main loop (8) into communication with branch circuits (16) and (25), which contain articles to be coated (23) and (32). The powder and air flow into those branch circuits and the powder coats the articles (23) and (32) by adhering to them by electrostatic attraction. Any powder that is not used is then returned in the flow of circulating air for reuse. After removing articles (23) and (32) from communication with the loop (8) and heating these articles to melt said powder the process is completed.

Abstract: A liquid display gun is disclosed wherein a spray pattern control valve assembly (32) is located internally of the gun. The spray pattern control valve assembly includes a two position air flow valve (102) movable between a first position wherein low air flow is supplied through the valve to a second position wherein high air flow is provided through the valve. The valve assembly has two adjustable stops (151. 154) operable to fix the low air flow and the high air flow positions of the valve. Manual pressure on the end of the shank (106) of the valve, controls movement between the two positions.

Abstract: A sprayhead for electrostatic spraying comprises an outer, non-conductive frusto-conical member (2) having channels (17) in its interior surface. An inner member (1) having two frusto-conical outer surface portions (7, 8) separated by step is fitted within said outer member (2) with one of the surface portions (7) engaging the interior surface of the outer member (2). In use, fluid flows through a flow pipe (10) to the channels through a groove (12) in the end of a stem of a metal screw (11) which secures the inner member (1) in position, the stem end being screw-threadedly engaged in the pipe (10). The pipe (10) is electrically charged and this charge is conducted therefrom through the screw to the metal inner member (1). Thus as fluid flows in the channels (17) in contact with surface portion (7) it is charged so that electrostatically charged spray droplets are produced at an edge (3) of the non-conducting outer member (2).

Abstract: Electrostatic spray coating method and apparatus, for spraying conductive coating material, utilizing nonconductive rotating cup-shaped atomizer and a charge-inducing elec- . trode proximate the periphery of the rotating cup whereat atomization occurs. The electrode, which is charged to one polarity from an electrostatic source, induces opposite polarity charge on the atomized particles. The charged particles are then attracted toward an object to be coated which is maintained at a potential sufficiently differentto attractthe charged particles to facilitate deposition of the coating on the object. The conductive coating can be either inherently conductive material, e.g. water-based paint, or nonconductive material, such as, solvent-based paint, which has been doped to render it conductive.
