Title: Innovations of William Ernest Cooke
Introduction
William Ernest Cooke is a notable inventor based in Kingston, Canada. He has made significant contributions to the field of electroplating and anodizing aluminum. With a total of four patents to his name, Cooke's work has advanced the techniques used in aluminum treatment processes.
Latest Patents
One of Cooke's latest patents is a process for electrolytic coloration of anodized aluminum. This innovative method allows a continuous length of aluminum to be anodized while passing through an anodizing electrolyte. The aluminum is then colored during its passage through an inorganic coloring electrolyte, where a counterelectrode is immersed. In this electrolytic coloring stage, alternating current with a superimposed D.C. compound is passed between the anodized aluminum and the counterelectrode. This process is designed to enhance the efficiency and quality of the anodizing and coloring stages.
Another significant patent by Cooke involves electroplating aluminum articles. In this process, the aluminum article is first treated electrolytically in a bath of caustic alkali, serving as the anode. This step is crucial for achieving a bare aluminum surface, free of anodic oxide film and pitting, which is essential for effective plating. The process is particularly suitable for continuous electroplating, allowing aluminum wire or strip to pass rapidly through the necessary baths.
