Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
152 words
A METHOD OF CONDUCTING A REACTION WHICH YIELDS EXOTHERMIC HEAT AND THE TEMPERATURE OF WHICH IS DESIRABLY CONTROLLED WHICH COMPRISES PASSING REACTANTS OF SUFFICIENT VOLATILITY TO ALLOW VAPORIZATION OF AT LEAST A PORTION THEREOF AT REDUCED PRESSRUE THROUGH A FIRST ELONGATED ZONE OR PASSAGEWAY MAINTAINED UNDER AN ELEVATED PRESSURE AT AN ELEVATED TEMPERATURE, ALLOWING REACTION TO TAKE PLACE IN SAID ZONE WHILE THE REACTANTS ARE FLOWING THERETHROUGH, THEN PASSING THE THUS-REACTED REACTANTS THROUGH A SECOND ELONGATED ZONE FOR PASSAGEWAY, ONE OF SAID FIRST AND SECOND ZONES CONTIGUOUSLY SURROUNDING AND ENCLOSING AT LEAST A PORTION OF THE OTHER OF SAID ZONES, THE PRESSURE ON THE REACTED REACTANTS IN SAID SECOND ZONE BEING SUFFCIENTLY REDUCED TO PROVIDE FOR VAPORIZATION AND EXPANSION OF AT LEAST A PART OF THE VOLATILE CONSTITUENTS IN THE REACTION PHASE TO PROVIDE A REDUCTION IN THE TEMPERATURE THEREOF AND A CONSEQUENT HEAT TRANSFER FROM SAID FIRST TO SAID SECOND ZONE.

Claim 3
Dependent Claim
129 words
HEAT EXCHANGE APPARATUS COMPRISING AN ELONGATED TUBE HAVING A CLOSED END, A SECOND TUBE DISPOSED WITHIN SAID ELONGATED TUBE AND FORMING ANNULUS THEREWITH EXTENDING SUBSTANTIALLY THE ENTIERE LENGTH OF SAID ELONGATED TUBE AND ALMOST TO SAID CLOSED END OF SAID ELONGATED TUBE, SAID SECOND TUBE BEING OPEN AT ITS EXTREMITY LOCATED NEAR SAID CLOSED END OF SAID ELONGATED TUBE THEREBY FORMING A CONTINUOUS PASSAGEWAY WITH SAID ANNULUS, SAID ANNULUS OR SAID SECOND TUBE HAVING THEREIN AT LEAST ONE PRESSURE DROP PRODUCING ORIFICE, COMPRISING A FLOW RESTRICTION INTERMEDIATE THE ENDS OF SAID SECOND TUBE HAVING A CROSS SECTIONAL AREA SUBSTANTIALLY LESS THAN THE CROSS SECTIONAL AREA OF SAID ANNULUS OR SAID SECOND TUBE, THE TUBES AT THEIR UPPER ENDS ARRANGED TO BE SEPARATEDLY IN OPEN COMMUNICATION WITH ANY DESIRED PLACE.
