摘要： A new apparatus and method for desalinating water. The principal impurities in sea water or brackish are in ionic form, which are removed by leaving purified water behind. The energy required to remove the ions may be partially recovered in this process and reused for further desalination, resulting in a further decrease in operating costs.

摘要： A system for the fused floride electrolysis of aluminum in a potcell wherein a carbonaceous anode and potlining are preserved against deterioration by impregnating their respective surfaces with a pitch-fluoride mixture and a pitch-graphite mixture. Atmospheric oxidation of anode surfaces is prevented so maximum anode cross sectional area is preserved and, hence, has minimum resistance for current travel through the anode and through the underlying electrolyte. The more dense carbon surface also reduces corner erosion of anodes. Impregnation is preferably carried out with one or more applications of aluminum fluoride suspended in a high melting, low volatile coal tar pitch. An improved potlining protects against electrolyte penetration and circulating metal erosion of the potlining surface, and improves conductivity; the lining bottom is sealed and smoothed with graphite suspended in molten pitch, which is absorbed by capillary attraction, and which increases conductivity. The lining walls are sealed and smoothed with a similar mixture of fluorspar and pitch, which decreases conductivity.

摘要翻译： 一种用于熔池中电解熔融铝的系统，其中通过用间距 - 氟化物混合物和沥青 - 石墨混合物浸渍其各自的表面来保留碳质阳极和陶瓷衬垫以防止劣化。 防止阳极表面的大气氧化，因此最大的阳极横截面面积被保留，并且因此具有通过阳极和通过下面的电解质的电流行进的最小电阻。 更致密的碳表面也减少了阳极的拐角侵蚀。 浸渍优选用一种或多种悬浮在高熔点，低挥发性煤焦油沥青中的氟化铝的应用来进行。 改进的potlining防止电解液渗透和循环金属腐蚀的表面，并提高电导率; 衬里底部被密封并且以悬浮在熔融沥青中的石墨进行平滑处理，其被毛细管吸引吸收并且增加了导电性。 衬里壁用氟石和沥青的类似混合物密封和平整，这降低了导电性。

摘要： 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.
