Title: Innovations of George G Promis, Jr.

Introduction

George G Promis, Jr. is a notable inventor based in Arvada, Colorado, recognized for his contributions to the field of electrophotographic copying technology. He holds two patents that showcase his innovative approach to solving complex problems in copying devices.

Latest Patents

Promis's latest patents include a "Motor Driving System" and a "Job Recovery Method and Apparatus." The motor driving system is particularly useful for driving scanning carriages in continuously variable reducing electrophotographic copiers. This system produces controlled and repeatable position acceleration and velocity profiles of the scanning carriage in relation to the motion of the copier drum. It features a single control loop for driving a servo motor, which provides the necessary drive for the scanning carriage. The system includes a driving signal source that generates a pulse train, with each pulse representing a desired increment of motor travel. Additionally, a tachometer monitors the servo motor's motion, producing output signals that help control the acceleration, velocity, and position profiles of the scanning carriage.

The job recovery method and apparatus address issues related to jamming during the copying process. This method allows for recovery from jams while generating duplex copies from either simplex or duplex originals. The apparatus includes various counters, memory registers, and comparators interconnected by logic circuitry to facilitate semi-automatic job recovery.
