Cryogenic oscillator

Claim 1

A CRYOGENIC OSCILLATOR COMPRISING A SOURCE OF SUBSTANTIALLY CONSTANT CURRENT, FIRST AND SECOND SUPERCONDUCTIVE CIRCUIT BRANCHES COUPLED IN PARALLEL ACROSS SAID SOURCE, A FIRST CRYOTRON HAVING A FIRST GATE INCLUDED IN SAID FIRST BRANCH AND A FIRST CONTROL CONDUCTOR INCLUDED IN SAID SECOND BRANCH, SAID FIRST CONTROL CONDUCTOR BEING DISPOSED IN CLOSE RELATION TO SAID FIRST GATE FOR APPLYING A MAGNETIC CIELD TO SAID FIRST GATE CAPABLE OF RENDERING IT RESISTIVE AS CURRENT FROM SAID SOURCE FLOWS IN SAID FIRST CONTROL CONDUCTOR, A SECOND CRYOTRON HAVING A SECOND GATE INCLUDED IN SAID SECOND BRANCH IN SERIES WITH SAID FIRST CONTROL CONDUCTOR AND HAVING A SECOND CONTROL CONDUCTOR INCLUDED IN SAID FIRST BRANCH IN SERIES WITH SAID FIRST GATE, THE SAID SECOND CONTROL CONDUCTOR BEING DIPOSED IN CLOSE RELATION TO THE SAID SECOND GATE FOR APPLYING A MAGNETIC FIELD TO THE SAID SECOND GATE CAPABLE OF RENDERING IT RESISTIVE WHEN CURRENT FROM SAID SOURCE FLOWS IN SAID SECOND CONTROL CONDUCTOR, AND MEANS ASSOCIATED WITH ONE OF SAID CONTROL CONDUCTORS AND INDEPENDENT OF SAID GATES FOR OPPOSING TO AN INCREASING DEGREE THE MAGNETIC EFFECT OF THE CURRENT SUPPLIED BY SAID SOURCE AS THE CURRENT FROM SAID SOURCE IN THE SAID ONE OF SAID CONTROL CONDUCTORS DECREASES.
