Title: The Innovations of Patrick John Walsh
Introduction
Patrick John Walsh is a notable inventor based in Newton, MA (US). He has made significant contributions to the field of superconductors, holding a total of 5 patents. His work focuses on advanced materials and processes that enhance the performance of oxide superconductors.
Latest Patents
One of his latest patents is titled "Simplified deformation-sintering process for oxide superconducting articles." This patent describes a method to prepare a highly textured oxide superconductor article in a single deformation-sinter process. The process involves creating a precursor article that includes a plurality of filaments made from a precursor oxide with a dominant amount of a tetragonal BSCCO 2212 phase. Each filament is surrounded by a constraining member and extends along the length of the article. The oxide article undergoes a heat treatment at a specific oxygen partial pressure and temperature to convert the tetragonal BSCCO 2212 oxide into an orthorhombic BSCCO 2212 oxide. Following this, the article is roll worked to achieve a significant reduction in thickness, ensuring that the filaments have dimensions equivalent to the longest dimension of the oxide superconductor grains. The final step involves sintering the rolled article to obtain a BSCCO 2223 oxide superconductor.
Another significant patent focuses on creating a high texture factor in an aspected multifilamentary oxide article. This article features a plurality of aspected filaments, each surrounded by a constraining member. The filaments have an average transverse cross-sectional thickness of less than about 35 µm and exhibit superior filament uniformity, hardness, and oxide density and texture.
