Sodium bicarbonate production

Claim 1

A METHOD OF PRODUCING SODIUM BICARBONATE WHICH COMPRISES ARRANGING A SERIES OF AT LEAST FOUR BODIES OF AMMONIATED BRINE IN HORIZONTALLY DISPOSED RELATION TO EACH OTHER IN A SERIES OF REACTION CHAMBERS FEEDING AMMONIATED BRINE IN TO THE LOWER PORTION OF THE FIRST OF SAID SERIES OF REACTION CHAMBERS, PASSING A GRAVITY FLOW OF BRINE FROM THE BOTTOM ZONE OF EACH CHAMBER EXCEPT THE LAST OF THE SERIES INTO THE BOTTOM ZONE OF THE ADJACENT SUCCEDING CHAMBER OF THE SERIES, WITHDRAWING THE BRINE FROM THE LOWER ZONE OF THE LAST CHAMBER OF THE SERIES AND DISCHARGE IT AT ATMOSPHERIC PRESSURE AT A HIGHER LEVEL BELOW THE TOPS OF SAID CHAMBERS TO MAINTAIN A CONSTANT LEVEL OF BRINE IN THE CHAMBERS, AND PASSING A STREAM OF GAS CONTAINING CARBON DIOXIDE SUCCESSVIELY THROUGH THE BODIES OF BRINE IN SAID SERIES FROM THE LAST TO THE FIRST THEREOF TO MAINTAIN A CONCENTRATION OF CARBON DIOXIDE IN SAID BODIES OF GRADUALLY INCREASING DEGREE FROM THE FIRST TO THE LAST THEREOF, SAID STREAM OF GAS BEING PASSED THROUGH THE BODIES BY SEPARATELY PUMPING THE UNABSORBED GAS FROM EACH CHAMBER EXCEPTING THE FIRST OF THE SERIES AT A GAUGE PRESSURE OF FROM ABOUT 3 TO ABOUT 5 POUNDS THROUGH EACH PRECEDING CHAMBER OF THE SERIES, SAID PRESSURE BEING ONLY SUFFICIENT TO OVERCOME THE STATIC HEAD PRESSURE OF THE BRINE IN THE RESPECTIVE CHAMBER, TO MAINTAIN SUBSTANTIALLY ATMOSPHERIC GAS PRESSURE ON THE SURFACE OF THE BODY OF BRINE IN EACH OF THE CHAMBERS.
