摘要： An electrostatic particle spray gun (10) having, in one preferred embodiment, a conical deflector (16) of insulative material mounted in the nozzle (14) in the particle path for forming a conical particle spray pattern. A resistive sheet (44) connected to a high voltage electrostatic supply is sandwiched between the forward (40) and rearward (42) ends of the deflector (16), leaving only the perimeter of the sheet exposed at the peripheral region of the conical deflector. The perimeter of the resistive sheet (44) functions as a multi-point circular electrode for charging the particles such that improved coating transfer efficiencies are achieved. Also, because of the resistive nature of the resistive sheet (44), the sheet constitutes a resistor in the electrical current path between the center of the sheet where it connects to a high voltage terminal and the circular periphery of the sheet which serves as the multiple point charging electrode, thereby minimizing unsafe electrical discharges should the electrode inadvertently approach a grounded object.

摘要： An apparatus for the electrostatic spraying of liquids, especially aqueous liquids, comprising a sprayhead chargeable to a high electrical potential and at least one electrode having a sharp edge or point. The electrode is so arranged and is maintained at such a potential that the generally radially directed electrical forces acting upon the surface of a liquid emerging from the sprayhead are reduced. The liquid then assumes a ligamentary form prior to atomisation.

摘要： An apparatus is disclosed suitable for electrostatic spraying from fixed wing aircraft. The apparatus includes a linear electrostatic spraying nozzle (2) and electrodes (4) placed near the nozzle's spraying edge to intensify the electric field strength at the spraying edge sufficiently to produce ligaments of the liquid to be sprayed from the spraying edge. In order that the airstream due to the aircraft's movement does not destroy the ligaments, the sprayhead and the electrodes are positioned so that part of the airstream flows between them. The spray head and the electrodes are so shaped and positioned that when directed to spray in substantially the same direction as the airstream, a turbulence free wake is left in the region of the ligaments.

摘要： A toner applicator assembly (18) for electrostatic drum printers featuring a toning shoe (17) with a biasing mechanism (32) in which the toning shoe is biased only at a single point (40). The toning shoe scans a sheet (13) having an electrostatic latent image supported on a rotating drum (11), in a helical path, and applies liquid developer to the sheet to develop the latent image. The toning shoe has a normal orientation which is skewed with respect to the drum's rotation axis (z) so as to follow a helical path. The toning shoe is movable with respect to three degrees of freedom ( theta , O &cir& /, psi ) relative to the normal orientation so as to automatically adjust its orientation to match the orientation of the sheet.

摘要： An electrostatic spraying apparatus having an electrostatic sprayhead (5) and a deflector (9) comprising an electrically conductive element (19) at least partially shrouded by electrically insulating material (17). The conductive element (19) is charged to an electrical potential of the same sign as the charge applied to the sprayhead and the deflector (9) is so positioned that charged spray droplets (15) are urged away from the deflector towards the crop (3). Leakage of charge from the conductive element is reduced by the presence of the insulating material.

摘要： 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.

摘要： 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.

摘要： 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.
