Title: The Innovations of Robert A. Covington, Jr.
Introduction
Robert A. Covington, Jr. is a notable inventor based in Wilmington, DE (US). He has made significant contributions to the field of materials science, particularly in the development of advanced polymers and ferromagnetic materials. With a total of 5 patents to his name, Covington has demonstrated a commitment to innovation and excellence in his work.
Latest Patents
One of Covington's latest patents is for the continuous synthesis of chromium dioxide. This process involves producing ferromagnetic chromium dioxide in a continuous operation by feeding a preheated paste of hydrated chromium oxides and additives into a twin screw reactor. The reaction occurs at elevated temperature and pressure for a short time while venting oxygen and steam. Water is injected near the end of the reaction zone to form a viscous chromium dioxide-water mixture, which is then cooled while passing through a pressure letdown extruder.
Another significant patent is for an in-line coagulation process for fluoroelastomer emulsions. This innovation allows for the in-line continuous coagulation and agglomeration of fluoroelastomers produced by emulsion polymerization. The process permits direct processing of fluoroelastomer latex into mechanical dewatering devices. Coagulant is injected into the fluoroelastomer latex countercurrent, and under high pressure, atomization and residence time prior to mechanical dewatering is controlled.
