Method and apparatus for analysis and control of organic systems

Claim 1

AN ANALYTICAL APPARATUS COMPRISING AN INFRARED LAMP, A CONTAINER FOR MATERIAL TO BE ANALYZED, WHICH CONTAINER IS PROVIDED WITH WALLS TRANSPARENT TO INFRARED LIGHT AND PERMITTING PASSAGE OF SUCH LIGHT THROUGH THE CONTAINER AND IS POSITIONED IN THE PATH OF LIGHT FROM SAID LAMP, A STATIONARY PLATE IN THE PATH OF A BEAM OF LIGHT TRANSMITTED THROUGH THE CONTAINER, WHICH PLATE IS REFLECTIVE OF AND TRANSMISSIVE TO THE LIGHT AT A NUMBER OF REGIONS THROUGHOUT AN EXTENDED AREA OF THE SAME SO THAT THE PLATE IS CAPABLE OF SPLITTING THE LIGHT BEAM INTO A TRANSMITTED BEAM AND A REFLECTED BEAM, BOTH OF WHICH SPLIT LIGHT BEAMS ORIGINATE FROM THE SAME GENERAL AREA OF THE PLATE, SAID STATIONARY PLATE BEING POSITIONED A DISTANCE FROM THE ABOVE-MENTIONED CONTAINER SUCH THAT A PARTICLE OF A LIGHT-ABSORPTIVE MATERIAL IN THE CONTAINER OBSTRUCTS LIGHT ABOUT EQUALLY FROM THE LIGHT TRANSMITTING AND LIGHT REFLECTIVE PORTIONS OF THE AREA OF THE PLATE, MEANS FOR DIRECTING THE REFLECTED AND TRANSMITTED BEAMS OF LIGHT FROM SAID PLATE TO DETECTORS, EACH OF WHICH IS ABSORPTIVE OF LIGHT AND WHICH HAS A PROPERTY OF ALTERING AN ELECTRIC POTENTIAL IN ACCORDANCE WITH THE AMOUNT OF LIGHT ENERGY ABSORBED AND WHICH DETECTORS ARE CONNECTED WITH THEIR POTENTIALS IN OPPOSITION, AND A MEANS IN THE PATH OF AT LEAST ONE OF THE BEAMS OF LIGHT FROM THE PLATE FOR ABSORBING INFRARED LIGHT OF CERTAIN WAVE LENGTHS MORE STRONGLY THAN LIGHT OF OTHER WAVE LENGTHS SO THAT ONLY CERTAIN OF THE WAVE LENGTHS OF LIGHT ARE STRONGLY ABSORBED BY THE DETECTOR.
