Quantized flux cryogenic device

Claim 1

AN INFORMATION STORAGE DEVICE COMPRISING, A CYLINDER MADE OF MATERIAL HAVING A SUPERCONDUCTIVE STATE AND A RESISTIVE STATE, MEANS FOR STORING A SELECTIVE NUMBER OF QUANTA OF FLUX IN SAID CYLINDER, A CORE POSITIONED INSIDE SAID CYLINDER, SAID CORE HAVING A SUPERCONDUCTIVE STATE AND A RESISTIVE STATE, MEANS FOR ELECTRICALLY INSULATING SAID CORE FROM SAID CYLINDER FOR OBTAINING A CRITICAL CURRENT OF SAID CORE WHICH IS DEPENDENT UPON THE NUMBER OF FLUX QUANTA STORED IN SAID CYLINDER, MEANS FOR PASSING CURRENT THROUGH SAID CORE TO DETERMINE THE AMOUNT OF CURRENT REQUIRED TO MAKE SAID CORE RESISTIVE, A CURRENT SOURCE FOR GENERATING AN INCREASING CURRENT OUTPUT, AND FIRST AND SECOND CURRENT PATHS CONNECTED TO SAID CURRENT SOURCE FOR OBTAINING NONDESTRUCTIVE READ OF SAID NUMBER OF FLUX QUANTA, SAID FIRST CURRENT PATH INCLUDING SAID CORE, SAID SECOND CURRENT PATH HAVING A HIGHER INDUCTANCE THATN SAID FIRST CURRENT PATH, WHEREBY THE CURRENT IN SAID FIRST CURRENT PATH INCREASES RAPIDLY AND THE CURRENT IN SAID SECOND CURRENT PATH INCREASES SLOWLY UNTIL THE CURRENT IN SAID FIRST PATH REACHES THE CRITICAL CURRENT OF SAID CORE AND THEREAFTER THE CURRENT IN SAID FIRST PATH REMAINS SUBSTANTIALLY CONSTANT AND THE CURRENT IN SAID SECOND CURRENT PATH INCREASES RAPIDLY.
