International Classification:

B05B 500

US Classification:

239690, 2396901, 239691, 239692, 239708, 239332

Abstract:

The present invention is an electrostatic spraying device to electrostatically charge and dispense a product from a reservoir to a point of dispersal that includes a nozzle having an exit orifice and being disposed at the point of dispersal to disperse the product. A channel is included that permits the electrostatic charging of product. A positive displacement mechanism is used to move the product from the reservoir to the nozzle. A power source supplies an electrical charge. A portion of a high voltage electrode being disposed between the reservoir and the nozzle is used to electrostatically charge product within the channel at a charging location. A distance between the charging location and the nozzle exit orifice is governed by V /d100,000, wherein V =an output voltage of said high voltage power supply and d=linear distance between the charging location and said nozzle exit orifice.

International Classification:

B05B 5/00

US Classification:

239690, 239692, 239704, 239706, 239708

Abstract:

An electrostatic spray device and a cartridge for an electrostatic spray device that reduce the occurrence of electrically induced emulsion product separation are disclosed. The device and/or the cartridge may reduce electrically induced emulsion product separation by providing a conductive high voltage shield substantially around the product reservoir. Alternatively, the device and/or the cartridge may prevent the product located at the charging location from being in fluid communication with the product reservoir so that the product that is being charged cannot flow back into the product reservoir. The device and/or cartridge may alternatively reduce electrically induced emulsion product separation by minimizing the volume of product between the charging location and the exit orifice of the nozzle.

Abstract:

Disclosed are ionographic imaging apparatuses and processes. One apparatus comprises an imaging means, means for applying to the imaging means a liquid material capable of forming a dielectric peel layer adhering to the imaging means, ionographic writing means for generating a latent image on the peel layer, means for developing the latent image on the peel layer, and means for simultaneously transferring the peel layer bearing the developed image from the imaging means to a substrate and affixing the peel layer bearing the developed image to the substrate. In another embodiment, the apparatus employs a process which comprises applying to an imaging means a liquid material capable of forming a dielectric peel layer adhering to the imaging means, forming a first latent image on the peel layer with an ionographic writing means, developing the first latent image with a first developer, forming a second latent image on the peel layer containing the first developed image with an ionographic writing means, developing the second latent image with a second developer, forming a third latent image on the peel layer containing the first and second developed images with an ionographic writing means, developing the third latent image with a third developer, and simultaneously transferring the portion of the peel layer that bears the developed images to a substrate and affixing the peel layer bearing the developed images to the substrate. A further embodiment is directed to an apparatus and process for sequentially forming and developing primary color images on an imaging means to form a full color image, followed by trasnsferring the fully formed image to a substrate, wherein the developers employed contain a release agent.
