Abstract: Hydrazine is produced in a two chamber electrolytic cell with anode and cathode chambers separated by an ion exchange membrane. When using an anion exchange membrane, ammonia and nonaqueous solvent are fed to the cathode compartment and hydrazine and solvent are collected from the anode compartment. When using a cation exchange membrane ammonia and nonaqueous solvent are fed to the anode compartment while hydrazine is also removed from the anode compartment. Similarly, alkyl hydrazines can be produced by feeding a lower alkyl amine instead of ammonia.

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.
