Multi-component infrared analyzer
First Claim
1. IN A PHOTOMETRIC ANALYZER, IN COMBINATION, A RADIATION SOURCE, A RADIATION DETECTOR, MEANS TO FORM A PAIR OF RADIATION BEAMS EXTENDING FROM SAID SOURCE TO SAID DETECTOR, A FIRST CELL DISPOSED IN THE FIRST OF SAID BEAMS, A PLURALITY OF SECOND CELLS DISPOSED TO BE DISPOSED SELECTIVELY IN THE SECOND OF SAID BEAMS, SAID FIRST AND SECOND CELLS BEING ADAPTED TO HOLD FLUID SUBSTANCES PREFERENTIALLY ABSORBING CERTAIN WAVE LENGTHS OF SAID RADIATION BEAMS, A MOTOR FOR MOVING SAID SECOND CELLS INTO AND OUT OF SAID SECOND BEAM, A SELECTOR SWITCH DRIVEN BY SAID MOTOR, A TIMER SWITCH IN THE MOTOR CIRCUIT FOR DEENERGIZING SAID MOTOR EACH TIME ONE OF SAID SECOND CELLS IS IN POSITION TO PERMIT PASSAGE THERETHROUGH OF SAID SECOND RADIATION BEAM, AND A FIXED CELL DISPOSED IN BOTH BEAMS OF RADIATION, SAID FIXED CELL BEING ADAPTED TO CONTAIN A SAMPLE TO BE ANALYZED.
