Patent No. 5,551,642

Electrostatic Dispersing Apparatus

Issued: September 3, 1996

Inventor: John P. Dunn, Penn Yan, NY

Assignee: Advanced Electrostatic Technologies, Inc., Hammondsport, NY

This invention utilizes the oscillation which is produced in a powder which is acted upon by an electrostatic field. The disperser accomplishes its task by electrically charging the powder in a high voltage DC filed or by contact with a charging electrode, this causes the powder to become polarized and repel or disperse into discrete particles. The passing of particles from one electrode toward a second of opposite polarity will place a charge on the particle which causes oscillation, dispersion and movement toward the second electrode. Additional dispersion of the powder takes place as the particles oscillate and impact against the electrodes during the decent through the apparatus. Particle oscillation is related to particle polarity changes that occur as the particles traverse through the system.
