摘要： A stream of carrier gas with powder particles is introduced at the feedingnd (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： A paint color change system and method for sequentially supplying different color electrically conductive paints to an electrostatic applicator. Paint is supplied through a supply hose to a first isolated reservoir and the supply hose is purged and dried to form a voltage block. While paint is supplied through a first delivery hose from the first reservoir to an applicator, a second reservoir is cleaned, paint is supplied to the second reservoir through a supply hose, and the supply hose is purged of paint and dried to form a voltage block. Upon completion of coating with the first color paint, the first delivery hose is purged of paint and dried to form a voltage block and paint then is supplied from the second reservoir through a second delivery hose to the coating applicator. If the same color paint is applied from both reservoirs, the first delivery hose can be cleaned and dried after paint delivery from the second reservoir has started to permit continuous coating.

摘要： An apparatus for surface treatment, especially for etching and/or coating workpieces by ion bombardment is described. This apparatus comprises at least one ionization chamber having at least one hot cathode, gas atoms being introduced into this chamber for the low-voltage arc-discharge between the ionization chamber and at least one anode inside the treatment chamber connected to a vacuum pump. At least one magnet coil mounted within the treatment chamber is used to control the ion density of the low-voltage arc-discharge and is mounted inside the treament chamber. The workpieces to be treated are arranged outside these magnet coils. Homogeneous surface treatment of the workpieces is ensured by the selected arrangement of magnet coils and workpieces.

摘要： A spray head for a spray nozzle including a hood providing a surface extending forward from the nozzle and also supporting insulating mountings for electrodes energizable to exert an inductive charging field or spray from the nozzle. The surface is earthed or earthy in operation to encourage collection of stray or return spray and stop stray or return spray affecting the charging field by landing on the electrodes or their mountings. The collected spray may be retained as liquid or caused to flow to projections to again leave the spray head as small droplets. The field from the electrodes may shape the spray.

摘要： A lance extension venturi sleeve is disposed preferably within the rear one-third of the lance extension of a powder spray gun. The sleeve increases the velocity of the powder stream and provides an abrupt opening to the larger lance extension tube. The velocity increase and the turbulence so created increase the homogeneity of the powder in the stream and produce a more uniform powder spray pattern or powder "cloud" for even powder coating of articles to be coated.

摘要： The process described herein comprises the mixing of a chilled gas into a stream of gas-suspended particles. Preferably the chilled gas is the same as the gas in which the particles are suspended and the particles are electrostatically charged. A novel device is described which provides a chamber extending lengthwise of the device into which channels feed the chilled gas into the particle suspension. The chilled gas is introduced from an external cooling system with the gas being advantageously cooled during passage through a coil whose outer walls are cooled by liquid nitrogen or dry ice. This process and device are of particular utility in a system for the spraying of electrostatically charged particles.

摘要： Atmospheric occurrences that decrease visibility, particularly fog, smoke, smog and the like, are cleared at sites such as airports by an array of EGD spray units emitting submicron size charged water droplets to attach to airborne particulates and electrostatically precipitate those to ground. Independent variables of the array and the EGD jets from the spray units are controlled to control the dependent variables characterizing the space-charge cloud thus developed. The methods and apparatus control the height to which clearing of the airborne particulates occurs to improve visibility and the time required for such clearing. Specific compact spray units are self-contained, can be radio operated, and are movable. Placement of the units for removal of radiation and advection fog with respect to airport runways include a square array of the spray units proximate the runway for radiation fog control and upwind location of arrays for advection fog precipitation. Specific characteristics of small, medium and large spray units suitable for use in the arrays are set forth.
