Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
128 words
IN THE METHOD OF EFFECTING A CHEMICAL REACTION SUCH AS OXIDATION, REDUCTION AND C ARBURIZATION BY DIRECTING A DETONATION WAVE AGAINST A COMMINUTED SOLID REACTANT TO PRODUCE A REACTION PRODUCT, WHEREIN A PREDETERMINED RATIO OF FUEL TO OXIDANT IN AN IGNITION ZONE PRODUCES OPTIMUM FLAME VELOCITY AND TEMPERATURE IN SAID DETONATION WAVE, AND WHEREIN THE ATMOSPHERE RESULTING FROM SAID DETONATION IS NOT THE OPTIMUM FOR EFFECTING AN EFFICIENT CHEMICAL REACTION OF SAID COMMINUTED SOLID REACTANT, THE IMPROVEMENT COMPRISING ADDING SUPPLEMENTAL REACTIVE GAS IN A REACTION ZONE ADJACENT TO THE IGNITION ZONE TO MODIFY THE DETONATABLE COMPOSITION IN SAID REACTION ZONE TO SUIT THE DESIRABLE REACTION CONDITIONS FOR SAID COMMINUTED SOLID REACTANT, THEREBY PROMOTING THE CHEMICAL REACTION OF SAID COMMINUTED SOLID REACTANT AND INCREASING THE YIELD OF REACTION PRODUCT.
Claim 2
Dependent Claim
