Latest Patents

One of her latest patents is a contamination control device for an electrostatographic development. This invention involves a development station designed for an electrostatographic reproduction apparatus. It utilizes pigmented marking particles from a mixture of pigmented marking particles and magnetic carrier particles to develop latent image charge patterns on a dielectric member. The development station features a housing that is positioned adjacent to the dielectric member, defining a reservoir for the particulate material mixture. It includes a mixer for blending the particulate material, a magnetic brush for applying the pigmented marking particles, and a transport system for moving the material from the mixer to the magnetic brush. Additionally, a contamination collecting device is integrated into the design, which employs a vacuum system to prevent contamination of the reproduction apparatus and its environment.

Another significant patent by Farnand is a method and apparatus for scavenging carrier employing a magnetic field. This invention focuses on the removal of magnetic carrier particles from a photoconductive image member. It involves subjecting the carrier particles to a magnetic field while or after exposing the photoconductive image member to erasing radiation, without a substantial electrical field affecting the carrier particles.
