Title: Innovations of Leo N Chapin
Introduction
Leo N Chapin is a notable inventor based in Park Ridge, IL (US). He has made significant contributions to the field of electrophotography, holding a total of 2 patents. His work has advanced the technology used in producing multi-color copies and single-color electrophotographic processes.
Latest Patents
Chapin's latest patents include a "Dry powdered or liquid developer compositions" which describes an electrophotographic process and materials for the production of multi-color copies. This invention involves applying an electrostatic charge to a receptor sheet that is subdivided into photoconductive segments. Each segment contains sensitizing components that cover different portions of the visible light spectrum. The exposed receptor is developed with a toner that allows for the transfer of dye color to copy sheets.
Another significant patent is the "Single color electrophotographic copy process." This invention focuses on a process where a receptor with a photoconductive coating is charged and exposed to an original. The non-imaged areas of the original discharge, leaving a latent electrostatic image. The developed receptor is then treated with a toner that acts as a solvent for the dispersed dye, facilitating the transfer of color to a copy sheet.
