Latest Patents

One of Harnois's latest patents is for encapsulated ceramic superconductors. This invention features a superconducting conductor designed for use in a preselected fluid cryogen. It includes a composite ceramic superconducting wire with an outer surface along its length, complemented by a sealing structure that hermetically surrounds the outer surface. This design prevents the cryogen from infiltrating the wire and degrading its superconducting properties, even under pressurized conditions. The superconducting conductor is applicable in superconducting cabling and coil applications. The sealing structure can be created by laminating metallic tapes to the wire, encircling at least one metallic sheet around the outer surface, welding multiple metallic sheets together, or forming a polymer coating that completely covers the wire's outer surface.

Another significant patent by Harnois involves methods for joining high-temperature superconducting components. This method minimizes critical current degradation while joining components, ensuring that the formed articles maintain critical currents that are at least 80% of the original components. The invention also provides splicing geometries that facilitate the wrapping of joined components around a mandrel or tube without causing kinking or flexion, thus preserving their performance.
