Device for recording nuclear resonance spectra

Claim 1

A DEVICE FOR RECORDING NUCLEAR RESONANCE SPECTRA OF A GIVEN SAMPLE, SAID DEVICE COMPRISING FIRST MAGNETIC FIELD PRODUCING MEANS HAVING FLUX LINES IN A SUBSTANTIALLY CONSTANT PREDETERMINED DIRECTION, SECOND MAGNETIC FIELD PRODUCING MEANS HAVING FLUX LINES ALTERNATING AT A HIGH FREQUENCY IN A DIRECTION, MEANS FOR VARYING AT LEAST ONE OF THE PREDETERMINED RESPECTIVE PARAMETERS OF SAID FIRST AND SECOND FIELD PRODUCING MEANS, SAID PARAMETERS COMPRISING THE FIELD INTENSITY OF SAID FIRST FIELD PRODUCING MEANS AND THE FREQUENCY OF SAID SECOND FIELD PRODUCING MEANS, RESPECTIVELY, SAID GIVEN SAMPLE BEING ADAPTED TO BE DISPOSED IN THE FIELDS OF SAID FIRST AND SECOND FIELD PRODUCING MEANS, A FIRST SIGNAL GENERATOR TO PROVIDE A FIRST SIGNAL HAVING A PREDTERMINED FIRST FREQUENCY, MEANS FOR MODULATING SAID FIRST SIGNAL IN ACCORDANCE WITH THE ENERGY ABSORBED BY SAID GIVEN SAMPLE DISPOSED IN SAID FIELDS, MEANS TO DEMODULATE SAID MODULATED FIRST SIGNAL TO PROVIDE AN OUTPUT SIGNAL PROPORTIONAL THERETO, A REFERENCE SAMPLE ADAPTED TO BE DISPOSED IN THE FIELD PRODUCED BY SAID FIRST MAGNETIC FIELD PRODUCING MEANS, A SECOND SIGNAL GENERATOR RESPONSIVE TO THE ENERGY SUPPLIED BY THE NUCLEAR PROCESSION OF SAID REFERENCE SAMPLE TO PROVIDE A SECOND SIGNAL HAVING A SECOND FREQUENCY DIFFERENT FROM SAID FIRST FREQUENCY, MEANS TO COMPARE SAID FIRST AND SIGNAL SIGNALS TO PROVIDE A CONTROL SIGNAL PROPORTIONAL TO THE DIFFERENCE IN SAID FIRST AND SECOND FREQUENCIES, AND INDICATING MEANS COMPRISING MEANS TO RECORD SAID OUTPUT SIGNAL, SAID MEANS TO RECORD BEING RESPONSIVE TO SAID CONTROL SIGNAL.

Claim 2

A DEVICE FOR RECORDING NUCLEAR RESONANCE SPECTRA OF A GIVEN SAMPLE, SAID DEVICE COMPRISING FIRST MAGNETIC FIELD PRODUCING MEANS HAVING FLUX LINES IN A SUBSTANTIALLY CONSTANT PREDETERMINED DIRECTION, SECOND MAGNETIC FIELD PRODUCING MEANS HAVING FLUX LINES ALTERNATING AT A HIGH FREQUENCY IN A DIRECTION, MEANS FOR VARYING AT LEAST ONE OF THE PREDETERMINED RESPECTIVE PARAMETERS OF SAID FIRST AND SECOND FIELD PRODUCING MEANS, SAID PARAMETERS COMPRISING THE FIELD INTENSITY OF SAID FIRST FIELD PRODUCING MEANS AND THE FREQUENCY OF SAID SECOND FIELD PRODUCING MEANS, RESPECTIVELY, SAID GIVEN SAMPLE BEING ADAPTED TO BE DISPOSED IN THE FIELDS OF SAID FIRST AND SECOND FIELD PRODUCING MEANS, A FIRST SIGNAL GENERATOR TO PROVIDE A FIRST SIGNAL HAVING A PREDTERMINED FIRST FREQUENCY, MEANS FOR MODULATING SAID FIRST SIGNAL IN ACCORDANCE WITH THE ENERGY ABSORBED BY SAID GIVEN SAMPLE DISPOSED IN SAID FIELDS, MEANS TO DEMODULATE SAID MODULATED FIRST SIGNAL TO PROVIDE AN OUTPUT SIGNAL PROPORTIONAL THERETO, A REFERENCE SAMPLE ADAPTED TO BE DISPOSED IN THE FIELD PRODUCED BY SAID FIRST MAGNETIC FIELD PRODUCING MEANS, A SECOND SIGNAL GENERATOR RESPONSIVE TO THE ENERGY SUPPLIED BY THE NUCLEAR PROCESSION OF SAID REFERENCE SAMPLE TO PROVIDE A SECOND SIGNAL HAVING A SECOND FREQUENCY DIFFERENT FROM SAID FIRST FREQUENCY, MEANS TO COMPARE SAID FIRST AND SIGNAL SIGNALS TO PROVIDE A CONTROL SIGNAL PROPORTIONAL TO THE DIFFERENCE IN SAID FIRST AND SECOND FREQUENCIES, AND INDICATING MEANS COMPRISING MEANS TO RECORD SAID OUTPUT SIGNAL, SAID MEANS TO RECORD BEING RESPONSIVE TO SAID CONTROL SIGNAL.
