Claim 1
Independent Claim
96 words
A SWITCH FOR SELECTIVELY DISTRIBUTING CURRENT TO A PLURALITY OF LOAD CIRCUITS CONNECTED IN PARALLEL WITH A CURRENT SOURCE, COMPRISING A PLURALITY OF DISCRETE SUPERCONDUCTIVE ELEMENTS, EACH ONE FOR CONNECTION IN A DIFFERENT ONE OF SAID LOAD CIRCUITS, AND MEANS FOR PRODUCING A SPACE VARYING MAGNETIC FIELD HAVING A NULL ZONE OF LEAST MAGNETIC FIELD STRENGTH FOR DESTROYING THE SUPERCONDUCTIVITY OF ALL BUT A PRESELECTED ONE OF SAID DISCRETE SUPERCONDUCTIVE ELEMENTS, SAID LATTER MEANS COMPRISING PLURAL ELECTROMAGNETIC MEANS EACH PRODUCING A FIELD IN THE SAME AREA OF A SUPERCONDUCTIVE ELEMENT ENABLING SAID ELEMENT TO BE SUPERCONDUCTIVE.
