1,165,350. Electrolyte circulation in a galvanic cell. ALLMANNA SVENSKA ELEKTRISKA A.B. 30 Dec., 1966 [31 Dec., 1965], No. 58273/66. Heading H1B. Electrolyte is circulated in a galvanic cell by means of a first storage vessel connected to the lower part of the electrolyte chamber by a conduit for one-way flow of electrolyte to the chamber and a second storage vessel connected to the upper part of the electrolyte chamber by a conduit for one-way flow of electrolyte to the vessel from the chamber and to the first storage vessel by a conduit outside the cell for one-way flow of electrolyte from the second to the first storage vessel, the flow of the electrolyte being effected by varying the gas pressure above the electrolyte in at least one of the storage vessels. As shown in Fig. 1, the pressure in the first vessel 10 is varied by a throttle valve 20 in the gas conduit 18; a rise in pressure forces electrolyte through the conduit 9, the electrolyte chamber 4 and conduit 11 to the second vessel 12; lowered pressure results in flow of electrolyte under hydrostatic pressure from vessel 12 through conduit 21 to vessel 10. In Fig. 2 (not shown), the gas pressure in vessel 12 is variable as in vessel 10 and one-way flow is obtained by inserting non-return valves in conduits 21 and 9 or 11. In Fig. 3 (not shown), gas from the fuel exhaust 6a, via a reducing valve, is used as the pressure-varying gas in vessel 10. In Fig. 4 (not shown), the pressurevarying gas is led into the electrolyte chamber to flush out possible dangerous accumulations of cell gases. Fig. 5 (not shown) illustrates a vessel 10 in which high electrolyte level operates a float valve causing gas to enter the vessel and produce electrolyte flow through conduit 9.
