Abstract: METHOD AND APPARATUS FOR THE DEIONIZATION OF ELECTROLYTE SOLUTIONS WHEREIN ALTERNATINGLY ORIENTED ANION-CATION BILAMINATE ION-EXCHANGE MEMBRANES DEFINE THE CHAMBERS OF A MULTICHAMBER ELECTRODIALYSIS CELL AND WHEREIN THE ANION EXCHANGE LAMINAE OF EACH OF SAID MEMBRANES BOUND THE SALT DILUTING CHAMBERS AND THE CATION EXCHANGE LAMINAE BOUND THE SALT CONCENTRATING CHAMBERS. A DIRECT ELECTRIC CURRENT IS PASSED TRANSVERSELY THROUGH ALL OF SAID CHAMBERS AND MEMBRANES WHICH CURRENT IS PERIODICALLY REVERSED.

Abstract: AN INSTRUMENT FOR MEASURING THE CONCENTRATION OF A WEAKLY WATER-IONIZABLE GASEOUS COMPONENT SUCH AS CARBON DIOXIDE WHICH MAY BE CONTAINED IN AN AMBIENT ATMOSPHERE. SUCH DEVICE IS INDEPENDENT OF THE TEMPERATURE AND TOTAL PRESSURE OF THE ATMOSPHERE AND IS BASED ON THE MEASURABLE CHANGES OCCURRING IN THE ELECRICAL PROPERTIES OF AN ION-EXCHANGE MATERIAL WHEN IN THE PRESENCE OF THE PARTICULAR GAS TO BE MEASURED.
