Title: Treatment of waste liquor from air-magnesium cell
Inventor: AIZAWA GENICHI
IPC: C02F1/66
Filed: 1979-06-28
Abstract: PURPOSE: To make waste liquor from an air-magnesium cell harmless and drain it by filtering the liquor to separate discharge products followed by neutralization with a weak acid.  
     CONSTITUTION: When an air-magnesium cell discharges, the electrolyte contains reaction product sludge and has a high pH value, so in the treatment of this waste liquor cell 4 is inverted to empty the liquor into waste liquor container 1 through filter cloth 2. Discharge products on cloth 2 are dried and discarded. On the other hand, a weak acid such as boric acid or carbonic acid is added to the filtrate and agitated to neutralize the filtrate, which is then drained. Thus, the waste liquor can simply be treated and made harmless.

Filed: 1987-04-03
Abstract: PURPOSE:To continuously and accurately measure oxygen activity over a long time, by specifying the mixing wt. ratio of the metal oxide particle and metal particle constituting a standard polar substance and setting the particle size of both particles to 200 mesh or less. CONSTITUTION:The mixing wt. ratio of the metal oxide particle and metal particle constituting the standard polar substance 3 of an oxygen measuring probe is set to 1/4-4 and the particle size of both particles is set to 200 mesh or less. In this case, the standard polar substance 3 is pref. constituted of a chromium oxide particle and a metal chromium particle. As mentioned above, by setting the particle size to 200 mesh or less, filling density is enhanced to sufficiently secure a contact area and, therefore, the lowering of accuracy during measurement can be prevented. Since the mixing wt. ratio is largely taken, even when continuous measurement is performed over a long time, the gradual lowering in oxygen electromotive force can be prevented.
