Claim 1
Independent Claim
125 words
A NOVEL METASTABLE SOLID METAL ALLOY FILM WHICH HAS NOT UNDERGONE THE NORMAL PROCESS OF NUCLEATION AND GROWTH OF EQUILIBRIUM PHASES PREPARED BY THE STEPS OF COMMINGLING THE CONSTITUENTS OF SAID ALLOY FILM, HEATING SAID CONSTITUTENTS TO A MOLTEN STATE UNDER HIGH PRESSURE, FORCIBLY IMPINGING THE PRESSURIZED MOLTEN CONSTITUTENTS UPON THE INTERIOR OF A ROTATING CHILLED CYLIDRICAL SURFACE, PERMITTING SAID MOLTEN CONSTITUENTS TO BE INSTANTLY FLATTENED TO A THICKNESS OF LESS THAN 100,000 ANGSTROMS ON SAID SURFACE BY CENTRIFUGAL FORCE AND ADHERING TO SAID CYLINDRICAL SURFACE, TO FORM AN INTIMATELY CONTACTED FILM THEREON, EXTRACTING HEAT FROM SAID CONSTITUENTS TO SAID SURFACE TO YIELD A NOVEL METASTABLE SOLID ALLOY FIRLM, AND SUBSEQUENTLY STOPPING SAID ROTATING SURFACE AND REMOVING SAID NOVEL COOLED ALLOY FILM FROM SAID SURFACE.
