Abstract: A system for electrostatic powder coating irregular shaped, three-dimensional articles with 10 μm average diameter powder particles. A supply of powder particles are triboelectrically charged and transported onto one or more donor rolls without the need from fluidization of the powder particles. The charged powder particles on the one or more donor rolls are metered to provide a uniform layer thereon. A combination of AC electric fields and/or air jet detach the powder particles from the one or more donor rolls and produce a powder cloud that is directed to the grounded article to be coated. A layer of powder particles coats the outer surface of the article, and the layer is subsequently cured to form a permanent and durable film on the article.

Abstract: A non-interactive development system generates a toner cloud in a development zone by an AC biased stationary electrode positioned in contact with the back surface of a movable toned dielectric donor belt having a patterned electrode structure on the front surface thereof. The AC biased electrode produces AC fringe fields near the edges of the patterned electrode structure that cause the generation of a toner cloud for developing an electrostatic latent image. The donor belt is partially wrapped around a magnetic brush to produce a toner loading zone. Isolated patterned electrodes on the donor belt near the entrance region of the toner loading zone are biased to cause unloading of toner from the donor belt, while isolated electrodes near the exit region of the toner loading zone are biased to cause toner reloading of the donor belt.

Abstract: A marking apparatus is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. Marking material, such as ink, toner, etc., is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. At sufficient velocity, and with appropriate marking material, the marking material may be kinetically fused to the substrate. A multiplicity of channels for directing the propellant and marking material allow for high throughput, high resolution marking. Multiple marking materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is a single-pass, full-color printer.
