    Abstract: An apparatus and process for spraying liquids wherein liquid emerging from a sprayhead is subjected to an electrical field sufficiently high for the liquid to be drawn from the sprayhead in the form of one or more filaments. The filament or filaments become unstable and subsequently break up into droplets. A stream of gas is caused to flow through the region of the high electrical field, the gas flowing in a direction parallel or substantially parallel with the direction in which the liquid emerges from the sprayhead. Droplets are thus removed from the region and a built-in in space charge is reduced.

    Abstract: The invention relates to a process and an apparatus for applying two or more colors of paint by applying a first paint to at least part of a substrate, followed by a second and, if desired, further different-colored paints to different parts of the substrate and hardening the applied coats of paint by baking, which comprises applying the second and if desired the further different-colored paints without interim baking of the first paint to the preselected different parts of the substrate using electrostatic atomization at stationary atomizer edges involving transport of the paint particles in an electric field and, after the first and subsequent paints have been applied, hardening all coats of paint together by baking.

    Abstract: Amorphous or microcrystalline alloy powder is prepared by the rapid quenching of ultrafine metallic spheroids generated from the molten metal state. The molten metal droplets are formed when an intense electric field (10.sup.5 V/cm) is applied to the surface of liquid metal held in a suitable container. The interactions between the intense electric field and liquid surface tension disrupts the metal surface, resulting in a beam of positively charged droplets. The liquid metal spheres generated by this electrohydrodynamic process are subsequently cooled by radiative heat transfer. Rapid cooling of the droplets may be accomplished by heat transfer to a low pressure gas by free molecular heat conductivity. Quenching rates exceeding 10.sup.6 .degree.K./sec are possible using this technique. Thin film coatings are prepared by electrohydrodynamically spraying a beam of charged droplets against a target (substrate). The target can be electrically controlled to effect the charged particles impact. The materials to be sprayed electrodynamically can be varied in both throughput and species such that a target can have multimaterial layers being deposited coincidentally or sequentially. The ultra small droplet size will enhance the physical properties by reducing skin stresses and enhance the optical properties by reducing the growth of crystallites in the film. Precise layers can be deposited from extremely thin films to thick filters for optical characteristics into the infrared. All materials that can be molten and contained can be electrohydrodynamically sprayed and controlled for depositions upon a substrate material.

    Abstract: An electrostatic generation device for an atomizer solves the problem of poor spraying effect of the atomizer. When the electrostatic generation device is used, the fan blows air through the water outlet pipe, and part of the airflow passes through the pressure tube into the water tank, continuously increasing the air pressure inside the water tank. The greater pressure forces the liquid inside the water tank into the inlet pipe and along the inlet pipe into the guide tube, spraying out from the guide tube in the direction away from the fan through the water outlet pipe. The liquid is electrified by the charged metal valve core, and the electrostatically charged liquid is sprayed out through the air outlet, forming electrostatically charged atomized particles. The spray can easily adhere to the object being sprayed, resulting in a higher spraying efficiency.
