Title: Thomas J Patrician: Innovator in Ceramic and Tungsten Technologies
Introduction
Thomas J Patrician is a notable inventor based in Monroeton, PA (US). He has made significant contributions to the fields of ceramic and tungsten technologies, holding a total of 15 patents. His innovative work has paved the way for advancements in various applications.
Latest Patents
Among his latest patents is a ceramic discharge vessel featuring a molybdenum alloy feedthrough. This invention describes a ceramic discharge vessel that includes a feedthrough made from a molybdenum alloy, which contains at least 75 weight percent molybdenum and more than 5 weight percent nickel, along with at least one other alloying metal selected from copper and iron. The weight ratio of nickel to the combined amount of copper and iron in the alloy is maintained between 1:1 to 9:1. This design ensures that the thermal expansion coefficient of the alloy is well-matched to that of the ceramic, allowing for a secure seal without causing cracking. Preferably, the feedthrough is directly sealed to the ceramic discharge vessel without the need for an intermediate frit material.
Another significant patent involves a method for making non-sag tungsten wire. This innovative process improves potassium retention in non-sag tungsten processing through a technique known as double doping. The method includes dry doping standard singly doped potassium-aluminum-silicon tungsten blue oxide with potassium nitrate, followed by standard reduction, acid washing, sintering, rolling, and drawing steps. Additionally, the method incorporates an aqueous extraction of the heteropolytungstate anion to predict potassium retention.
