Title: The Innovative Contributions of Herbert L. Eiselstein
Introduction
Herbert L. Eiselstein is a notable inventor based in Huntington, WV (US), recognized for his significant contributions to materials science and engineering. With a total of 6 patents to his name, Eiselstein has developed innovative solutions that address critical challenges in various industries.
Latest Patents
Eiselstein's latest patents include a corrosion-resistant high-strength nickel-base alloy. This alloy features special and correlated percentages of chromium, iron, molybdenum, titanium, columbium, and aluminum. It provides an attractive combination of strength, ductility, and resistance to environmental media. The alloy can be processed by cold working and age hardening to achieve yield strengths ranging from 150,000 psi (1034 MPa) to 200,000 psi (1379 MPa), along with tensile elongations of 10% to 20%. Additionally, it is resistant to corrosive media such as hydrogen sulfide and acid chloride solutions, making it useful for applications in petroleum production tubing and sulfur dioxide gas scrubber systems.
Another significant patent involves an apparatus and method for fabricating tubes from powder. This invention features a retractable, rotating mandrel disposed within a powder hopper, circumscribed by a plurality of swaging dies. A flexible iris reduces powder loss during the fabrication process. As the mandrel is withdrawn, the dies compact the powder to form a continuous tube, which is then withdrawn along with the mandrel.
