Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
132 words
THE METHOD OF CARRYING ON GASEOUS REACTIONS IN WHICH BY-PRODUCTS TEND TO DEPOSIT WHICH COMPRISES FLOWING A MIXTURE OF REACTANTS INTO A JACKETED REACTION CHAMBER AND ESTABLISHING A REACTION THEREIN, FORCING A SCREEN LIQUID FROM THE JACKET ONTO THE INTERIOR SURFACE OF THE CHAMBER NEAR THE TOP OF THE REACTION ZONE THEREIN, AND FORMING THEREBY A CONTINUOUS LIQUID SCREEN AROUND THE REACTION ZONE WITH DESCENDING HELICAL FLOW, FLOWING ADDITIONAL SCREEN LIQUID IN HEAT-EXCHANGE RELATION TO, BUT SEPARATED FROM THE LIQUID SCREEN AROUND THE REACTION ZONE AND CONTROLLING THE TEMPERATURE OF SAID FLOWING SCREEN, AS IT PROGRESSES ALONG THE REACTION ZONE, BY HEAT-EXCHANGE TO SAID ADDITIONAL SCREEN LIQUID, SAID LIQUID SCREEN BEING INJECTED THROUGH PRESSURE JETS INCLINED AT AN ANGLE TO THE AXIS OF SAID REACTION ZONE FOR PRODUCING SAID DESCENDING HELICAL FLOW.

Claim 3
Dependent Claim
86 words
APPARATUS FOR CARRYING ON PYROLYSIS REACTIONS WHICH COMPRISES AN UPSTANDING TUBULAR WALL, A RING FITTED INTO THE TOP OF THE TUBE SUBSTANTIALLY AGAINST THE INNER FACE THEREOF, AND HAVING ON ITS OUTER FACE TOWARD SAID WALL CLOSELY SPACED HELICAL GROOVES OPEN AT THEIR LOWER INTERIOR END, AND A HEADER COMMUNICATING WITH THE UPPER EXTERIOR ENDS OF SAID GROOVES TO FEED A LIQUID THROUGH THEM ONTO SAID INNER FACE UNDER SUBSTANTIALLY PRESSURE FOR PRODUCING AND MAINTAINING A SUBSTANTIALLY CONTINUOUS HELICALLY FLOWING LIQUID SCREEN WITHIN SAID TUBULAR WALL.
