Gyromagnetic spectrometer having separate dispersion and absorption mode detectors

Claim 1

IN A GYROMAGNETIC RESONANCE SPECTROMETER, MEANS FORMING A RESONATOR STRUCTURE FOR CONTAINING A SAMPLE OF MATTER TO BE ANALYZED WHILE IMMERSED IN A UNIDIRECTIONAL POLARIZING MAGNETIC FIELD, MEANS FORMING A SOURCE OF AN ALTERNATING SIGNAL APPLIED TO SAID RESONATOR STRUCTURE FOR EXCITING SAID RESONATOR STRUCTURE TO PRODUCE AN ALTERNATING MAGNETIC FIELD IN THE SAMPLE TO EXCITE GYROMAGNETIC RESONANCE OF THE SAMPLE WHILE IMMERSED IN THE POLARIZING MAGNETIC FIELD, MEANS FORMING A MIXER STRUCTURE HAVING A PAIR OF DETECTOR MEANS THEREIN, MEANS FORMING A RESONANCE SIGNAL CHANNEL FOR APPLYING A RESONANCE SIGNAL DERIVED FROM SAID RESONATOR STRUCTURE TO SAID MIXER STRUCTURE, MEANS FORMING A REFERENCE SIGNAL CHANNEL FOR APPLYING A REFERENCE SIGNAL DERIVED FROM SAID SOURCE OF ALTERNATING SIGNAL TO SAID MIXER STRUCTURE, THE REFERENCE SIGNAL AND THE RESONANCE SIGNAL BEING COMBINED IN EACH OF SAID DETECTOR MEANS WITHIN SAID MIXER MEANS TO PRODUCE A PAIR OF OUTPUT SIGNALS, MEANS FORMING A PHASE SHIFTER IN SAID MIXER STRUCTURE FOR SHIFTING THE PHASE OF THE SIGNALS APPLIED THERETO FROM SAID SIGNAL AND REFERENCE CHANNELS SUCH THAT THE REFERENCE AND RESONANCE SIGNALS ARE COMBINED IN ONE OF SAID DETECTOR MEANS WITH A CERTAIN PHASE RELATION, AND THE REFERENCE AND RESONANCE SIGNALS ARE COMBINED IN THE OTHER ONE OF SAID DETECTOR MEANS WITH A PHASE RELATION BETWEEN THEM WHICH IS DIFFERENT FROM THE FIRST CERTAIN PHASE RELATION BY APPROXIMATELY 90*, WHEREBY WHEN THE OUTPUT OF ONE OF SAID DETECTOR MEANS IS PREDOMINANTLY CHARACTERISTIC OF THE DISPERSION RESONANCE MODE OF THE SAMPLE THE OUTPUT OF THE OTHER DETECTOR MEANS IS PREDOMINANTLY CHARACTERISTIC OF THE ABSORPTION RESONANCE MODE OF THE SAMPLE.
