His work is primarily associated with Xerox Corporation, a leading company in the imaging and printing industry.

Latest Patents

Bortfeldt holds a patent for a "Toner Fine Recovery System." This apparatus is designed to recover toner fines from a recirculating liquid that transports toner pellets cut from extruded toner. The system effectively cleans the pellet cutter while forming a mixture of liquid and toner fines. The recovery unit is strategically positioned between the pellet cutter and the station that discharges the pellets. This design ensures that clean liquid flows into the pellet cutter during each cycle. The recovery unit features a housing that defines a chamber with two sections. A sloping screen covers one of the chamber sections, allowing the mixture of toner fines and liquid to be dispensed onto the screen. The liquid passes through the screen and is recirculated, while toner fines collect on the screen. A backwash system then washes the toner fines from the screen into the other section of the chamber. The mixture is subsequently pumped into a separator, where toner fines are separated from the liquid and reused in the extruder. Liquid from the separator is returned to the other chamber section.
