6416158 Ballistic aerosol marking apparatus with stacked electrode structure July 9, 2002
A device for the transport and/or metering of marking material includes a plurality of phased electrodes, for example formed on a substrate. An electrostatic traveling wave may be generated along the electrodes to sequentially attract particles of marking material, and thereby transport
6328436 Electro-static particulate source, circulation, and valving system for ballistic aerosol marking December 11, 2001
In a ballistic aerosol marking device or the like, marking material flows from a material reservoir to a delivery channel via a port. Flow of marking material is facilitated by the provision of electrostatic marking material moving structures in or near the walls of the marking material
6293659 Particulate source, circulation, and valving system for ballistic aerosol marking September 25, 2001
A ballistic aerosol marking device includes, marking material which flows from a material reservoir to a delivery channel via a port. Flow of marking material is facilitated by the creation of a fluidized bed or aerosol of marking material in the reservoir. Gas flow together with mec
6292643 Printing system for applying a mixed combination of colorants for one separation to a photorecep September 18, 2001
In a xerographic printer, the use of traveling wave toner transport devices to deliver toner from the individual single color toner sumps to an intermediate traveling wave belt by utilizing traveling wave roll-type devices, and the traveling wave belt to carry the combination of toners t
6291088 Inorganic overcoat for particulate transport electrode grid September 18, 2001
An inorganic, top-surface, semiconducting dielectric overcoat, having a selected time constant permits electric field charge and dissipation at a selected rate to facilitate particulate material movement over an underlying electrode grid. The coating may be made from nitrides, oxides
6290342 Particulate marking material transport apparatus utilizing traveling electrostatic waves September 18, 2001
A device for the transport of particulate marking material includes a plurality of interdigitated electrodes formed on a substrate. An electrostatic traveling wave may be generated across the electrodes to sequentially attract particles of marking material, and thereby transport them
6265050 Organic overcoat for electrode grid July 24, 2001
An organic, top-surface, semiconducting dielectric overcoat, having a selected time constant permits electric field charge and dissipation at a selected rate to facilitate particulate material movement over an underlying electrode grid. The coating may be made from a compound includi
6201633 Micro-electromechanical based bistable color display sheets March 13, 2001
