Introduction

David Krus, Jr. is an accomplished inventor based in University Heights, OH. He has made significant contributions to the field of electroplating and drilling technology. With a total of two patents to his name, Krus has demonstrated his expertise and innovative spirit in his work.

Latest Patents

Krus's latest patents include the "Manufacture of fine-grained electroplating anodes" and the "Threaded spacer." The first patent describes a process for creating a continuously cast copper ingot, which involves imparting turbulence to the metal/solid interface during casting. This innovative method results in a hot-worked billet that has a smaller average grain size and a larger diameter, making it particularly useful for electroplating anodes in the damascene process for silicon wafers. The second patent focuses on an improved thin-walled threaded spacer designed to prevent thread galling in adjacent sections of drill pipe. This spacer is formed by mechanically deforming a copper/beryllium alloy strip, resulting in a preform with a hollow, truncated conical section and helical grooves.
