Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
51 words
IN A CALORIMETRIC METHOD FOR QUANITATIVELY INVESTIGATING THE HEAT PRODUCING CHARACTERISTICS OF PHOTOCHEMICAL REACTIONS, THE IMPROVEMENT OF RESTRAINING THE SUBSTANCES INVOLVED IN SAID PHOTOCHEMICAL REACTION SO AS TO FORM SAID SUBSTANCES INTO AN ANNULUS AND ILUMINATING THE INNER BOUNDARY SURFACE OF SAID ANNULUS WITH CHEMILUMINESCENCE THEREBY TO START SAID PHOTOCHEMICAL REACTION.
Claim 2
Dependent Claim
58 words
FOR USE IN A CALORIMETER FOR INVESTIGATING THE THERMAL RESPONSE OF A PHOTOCHEMICAL REACTION, A REACTION VESSEL, SAID REACTION VESSEL HAVING INNER AND OUTER ANNULAR COMPARTMENTS FOR ACCOMODATING A CHEMILUMINESCENT REACTION AND A PHOTOCHEMICAL REACTION, RESPECTIVELY; AND MEANS FOR DIRECTING SUBSTANTIALLY ALL OF THE LIGHT PRODUCED IN SAID INNER COMPARTMENT BY SAID CHEMILUMINESCENT REACTION INTO SAID OUTER COMPARTMENT.
