Title: Arthur G Metcalfe: Innovator in Metal Forming Technologies
Introduction
Arthur G Metcalfe is a notable inventor based in National City, CA (US), recognized for his contributions to the field of metal forming technologies. With a total of five patents to his name, Metcalfe has made significant advancements in the methods and apparatuses used for processing metallic materials.
Latest Patents
One of his latest patents is the Isothermal Sheet Rolling Mill. This invention discloses a method and apparatus for the solid-state forming of a metallic feedstock into thin sheets or foils. The innovation utilizes improved isothermal roll forging techniques, which include the use of rotatable backup rolls to enhance hollow work roll stiffness, two independent work roll heating controllers, and a reduced work roll diameter. These improvements allow for precise control of conditions within a feedstock 'travelling hot zone' (THZ). This technology is particularly beneficial for rolling thin sheets from challenging high-strength metals such as aluminides, intermetallics, superalloys, titanium alloys, and ODS composites, achieving widths of 24 inches and more.
Another significant patent is the Recuperator Tube Assembly. This invention features a ceramic to metal joint that is especially advantageous in a recuperator tube assembly. It includes a ceramic tube and a spaced, circumferentially disposed metal sleeve, with a bonding material cast between the ceramic and metal members. The seal member is designed to maintain an effective fluid seal while allowing for sufficient ductility within a predetermined thermal operating range. This invention is particularly useful in constructing modular heat exchanger units, where individual tube assemblies can be removed for cleaning, inspection, or replacement.
