207,630. Scott, J. P. Sept. 4, 1922. Oxygen and hydrogen, generating; electrolytes, treating non-chemically.-In an apparatus for generating oxygen and hydrogen, the oxygen carrying with it some of the anolyte passes from the anode chambers of a generator 10 by pipes 17 to a collecting pipe 18 connected to a separator 11 bv a pipe 22 entering below the water level and also by pipes 19, 20 entering above the water level. The separated liquid leaves by an upstanding pipe 28<a> and returns to the anode chambers by pipes 28 - - 32. The amount of water electrolysed is restored to the vessel 11 from a chamber 13 by pipes 47, 48, back-flow of electrolyte being prevented by a check-valve 51. The gas passes from the separator to the chamber 13 where it is washed, entering below the waterlevel, and passes thence to a storage chamber. A similar circulation and delivery apparatus are provided for the catholyte and hydrogen. The chamber 13 and the corresponding chamber in the catholyte system are connected at the bottom by a horizontal pipe connected by a central vertical pipe to a feed-water supply chamber in which the level is maintained constant by a float-valve. The separator 11 and the catholyte separator may also be connected at the bottom by a horizontal pipe. The gas-inlet pipe of the chamber 13 may be of adjustable depth as at 41a, and that on the hydrogen side is preferably lower; it is stated that this causes a greater proportion of feedwater to enter on the cathode side to counteract the concentration produced by the electrolysis. A filter screen 68 consisting of several sheets of metal gauze welded at their edges to a ring 69 is clamped between two parts of the separator 11. A similar screen is provided in the chamber 13. Insulating sections such as 25, 26 may be connected in various parts of the pipe system. A thermometer 23 may be inserted in the pipe 22. The section 25 is of glass and serves as a gauge. The pipes and chambers may be lagged to conserve heat. When the apparatus is worked as the off-peak load of a supply system, heaters such as H may be provided to establish rapidly the temperature of maximum efficiency. Hand valves may be provided at 72 and other parts of the system. The generators may be mounted on wheeled trucks 81. They are connected in series by expansible loops 16.
