Title: Clem J Nagley: Innovator in Electrophotographic Technology

Introduction

Clem J Nagley is a notable inventor based in Rochester, NY (US). He has made significant contributions to the field of electrophotographic printing technology. His innovative work has led to the development of a unique patent that enhances the functionality of developer units in printing machines.

Latest Patents

Clem J Nagley holds a patent for a developer unit that discharges used carrier particles using a magnetic valve. This developer unit is designed to develop an electrostatic latent image recorded on a photoconductive member used in electrophotographic printing machines. The technology involves a developer material that ages during the life of the printing machine. To extend the life of this developer material, additional developer material, including carrier granules and toner particles, is supplied. The discharge of developer material is controlled by a permanent magnet and an electromagnet positioned adjacent to an exit port in the developer unit. The permanent magnet creates a magnetic flux field that forms a developer material curtain, preventing the passage of developer material. When the electromagnet is energized, it attracts developer material from this curtain, allowing for controlled discharge.
