Title: Innovations of Lawrence E. Clifford
Introduction
Lawrence E. Clifford is a notable inventor based in Danbury, CT (US). He holds a total of 3 patents that showcase his contributions to the field of photocopying technology. His work has significantly impacted the efficiency and functionality of copying machines.
Latest Patents
One of his latest patents is a "Copying machine with electromagnetic scavenger assembly and process." This invention employs an electrostatic copying method that utilizes a two-component image-developer composition. It features a unique electromagnetic scavenger assembly that effectively removes magnetizable carrier particles from the photoconductive surface during the copying cycle. The electromagnet creates a strong magnetic field, drawing particles against a shield, which then allows them to fall into a collection tray after the cycle is complete.
Another significant patent is the "Powder density control circuit for a photocopier." This invention provides a means to control the powder density in a photocopier machine. It includes a high-value resistance and a bias supply that are coupled to a magnetic brush of the developer assembly. The voltage across the magnetic brush indicates how heavily the latent image is being toned, allowing for precise adjustments to the toner supply.
