Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
116 words
IN A SUPERCONDUCTING ELECTROMAGNET COMPRISING A COIL WOUND ON A MAGNET FORM, THE COIL HAVING A PLURALITY OF LAYERS OF SUPERCONDUCTING WIRE WITH EACH LAYER HAVING A PLURALITY OF ADJACENT TURNS OF SAID WIRE, WHEREIN WHEN SAID MAGNET IN AN ENERGIZED SUPERCONDUCTIVE STATE GOES TO A NORMALLY CONDUCTIVE STATE, SUBSTANTIAL VOLTAGE STRESSES OCCUR ORDINARILY DAMAGING TO DIELECTRIC MATERIAL PRESENT FOR PROVIDING INSULATION BETWEEN ADJACENT COIL LAYERS OF THE MAGNET, WHEREBY THE LIFE OF THE MAGNET IS SHORTENED, THE IMPROVEMENT FOR INCREASING MAGNET LIFE AND EFFICIENCY COMPRISING A THIN SHEET OF NORMALLY CONDUCTIVE MATERIAL POSITIONED BETWEEN SAID ADJACENT COIL LAYERS, AND MEANS SEPARATING SAID ADJACENT TURNS OF SUPERCONDUCTING WIRE TO ELECTRICALLY INSULATE THESE TURNS FROM EACH OTHER.
