Title: Richard P Wischnef: Innovator in Xerographic Technology

Introduction

Richard P Wischnef is a notable inventor based in Huntington Beach, California. He has made significant contributions to the field of xerographic technology, particularly with his innovative designs that enhance the functionality of copiers. His work has led to the development of a unique photoconductive belt system that improves the efficiency of xerographic copiers.

Latest Patents

Wischnef holds a patent for a "Flexible belt xerographic copier." This invention features a novel photoconductive belt and drive structure. The thin metal belt is designed with at least one transverse break or gap and is preferably formed of two belt segments. In operation, the break or gap between segments is maintained in an end-to-end relationship by tow bars that captivate the edges of the segments, ensuring they remain in position while providing mechanical bias. The photoconductive belt is driven in a unique manner by means of the tow bars, which are drawn about a non-circular path by an inelastic but flexible guide means such as chains and sprockets. The belt passes over drums that support it and define its path without driving it. These drums are equipped with a low friction surface and a soft layer to accommodate small foreign objects that may pass between the belt and the drums without damaging the belt. The tow bars project only on the inner side of the belt, and provisions are made for accommodating them on the drums to avoid excessive bending of the photoconductor bearing surface.
