Claim 1
Independent Claim
138 words
A DEVICE FOR PRODUCING HIGH INTENSITY MAGNETIC FIELDS OF SHORT DURATION, COMPRISING A SUPERCONDUCTING PRIMARY EXCITATION WINDING, SAID PRIMARY EXCITATION WINDING HAVING A NUMBER OF TURNS HAVING OHMIC RESISTANCE AND INDUCTIVITY; DIRECT CURRENT SUPPLY MEANS ELECTRICALLY CONNECTED TO SAID PRIMARY EXCITATION WINDING FOR PRODUCING A CURRENT FLOW THROUGH SAID PRIMARY EXCITATION WINDING; A SECONDARY WINDING INDUCTIVELY COUPLED WITH SAID PRIMARY EXCITATION WINDING, AND SECONDARY WINDING HAVING A NUMBER OF TURNS CONSIDERABLY LESS THAN THOSE OF SAID PRIMARY EXCITATION WINDING AND HAVING CONSIDERABLY LESS OHMIC RESISTACE AND CONSIDERABLY LESS INDUCTIVITY THAN SAID PRIMARY EXCITATION WINDING; A NORMAL CONDUCTANCE LOAD WINDING ELECTRICALLY CONNECTED TO SAID SECONDARY WINDING AND ENERGIZED BY SAID SECONDARY WINDING; AND TRANSITION CONTROL MEANS CONNECTED TO A PLURALITY OF SPACED POINTS ON SAID PRIMARY EXCITATION WINDING FOR CHANGING SAID PRIMARY EXCITATION WINDING FROM SUPERCONDUCTANCE TO NORMAL CONDUCTANCE.
