Nuclear magnetic resonance spin oscillator

Claim 1

A MAGNETIC RESONANCE SPIN GENERATOR COMPRISING: FIRST WINDING MEANS; MEANS MOUNTING SAID FIRST WINDING MEANS ALONG A FIRST AXIS; SECOND WINDING MEANS, SAID SECOND WINDING MEANS COMPRISING TWO SUBSTANTIALLY IDENTICAL COILS; MEANS MOUNTING SAID COILS OF SAID SECOND WINDING MEANS APPROXIMATELY PARALLEL AND ADJACENT TO A SECOND AXIS AND WITHIN SAID FIRST WINDING MEANS, SAID SECOND AXIS BEING APPROXIMATELY PERPENDICULAR TO SAID FIRST AXIS; A SAMPLE COMPOSED OF DIAMAGNETIC MATERIAL, SAID DIAMAGNETIC MATERIAL BEING CHARACTERIZED BY ATOMS WITH ELEMENTARY PARTICLES HAVING NON-ZERO MAGNETIC MOMENTS CAPABLE OF UNDERGOING PRECESSION AT THE LARMOR FREQUENCY ABOUT ONE AXIS IN A FIRST DIRECTION, SAID SAMPLE BEING POSITIONED WITHIN ONE OF SAID COILS OF SAID SECOND WINDING MEANS; MEANS FOR PRODUCING A UNIDIRECTIONAL MAGNETIC FIELD MUTUALLY PERPENDICULAR TO SAID FIRST AND SECOND AXES, SAID MAGNETIC FIELD CAUSING SAID MAGNETIC MOMENTS OF SAID PARTICLES TO ORIENT IN A FIRST DIRECTION; MEANS ENERGIZING SAID FIRST WINDING MEANS PRODUCING AN ALTERNATING MAGNETIC FIELD, SUBSTANTIALLY AT SAID LARMOR FREQUENCY TO EFFECT SAID PRECESSION FOR INDUCING A PRECESSION VOLTAGE IN SAID ONE OF SAID COILS, AND SAID TWO COILS OF SAID SECOND WINDING MEANS BEING DISPOSED TO HAVE SUBSTANTIALLY EQUAL VOLTAGES INDUCED THEREIN BY SAID ALTERNATING MAGNETIC FIELD; AND MEANS CONNECTD TO SAID COILS AND RESPONSIVE TO THE DIFFERENCE OF THE VOLTAGES INDUCED IN SAID COILS FOR PROVIDING A COMPENSATED SIGNAL VOLTAGE AT SAID LARMOR FREQUENCY, SAID LAST NAMED MEANS COMPRISING SAID MEANS ENERGIZING SAID FIRST WINDING MEANS, WHEREBY AN OSCILLATION SIGNAL AT THE LARMOR PRECESSION FREQUENCY OF SAID PARTICLES IS SUSTAINED.
