Title: Innovations of Toshimichi Ukena
Introduction
Toshimichi Ukena is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of electroplating and metal recovery. With a total of 3 patents to his name, Ukena's work focuses on improving the efficiency and environmental impact of metal recovery processes.
Latest Patents
One of Ukena's latest patents is a method for recovering metallic tin from electroplating sludge. This innovative process enhances the recovery of tin from sludge formed during halogen-type electrolytic tinplating of steel sheets. The method involves leaching the sludge with water at a pH of 7 or less, separating the iron-containing sludge, and alkalifying the filtrate to deposit tin-containing sludge. This process not only recovers high purity metallic tin at a high yield but also allows for the recovery of other materials for reuse, minimizing environmental pollution.
Another significant patent is an apparatus for plating metal strips in an electrolytic cell. This apparatus features a supporting roll that is strategically positioned to reduce the catenary of the metal strip. The design ensures that the distance between the supporting roll and deflector rolls is optimized to maintain efficiency during the plating process.
