STATEMENT OF CLASS SUBJECT MATTER
This is the generic class for subject matter involving (a) superconductortechnology above 30 K and (b) Art collections involving superconductortechnology. Apparatus, devices, materials, and processes involvingsuch technology are included herein.
(1)Note. Precursors of high temperature (Tcgreaterthan 30 K) superconducting material under the class definition orprocess of producing the same are placed in this class if proportionallyconstituted to provide the desired superconducting product upon decomposition,heating, deoxygenation, or oxidation.The following class(es)/subclass(es) in Referencesto Other Classes, below, specifically provide for subject matterincluding superconductors functioning at temperatures of 30Kand below.
