PROCESS FOR THE MANUFACTURE OF METALLIC SODIUM.
Specification of Letters Patent.
971,198. Patented Sept. 2%, 1916.

then'to replace it in position. Such water or solution constitutes a restorative liquid. By this process the working remains regular, the decrease in the production is arrested and the inconvenience, due to the frequent replacement of the caustic soda and to the dismounting of the whole apparatus, is entirely removed.
It should be noted-that in the present case there is not visible manifestation of dirt deposition on the cathode and that the new may concern: Be it known that I, PAUL Liion HULIN, of
lie ,of France, engineer, have 'invented a Process for the M anufacture of Metallic Soof which the following is a full, clear,
l and exact description, this being a division of my application for Letters Patent fori means for the electrolytic manufacture of sodium, Serial No. 459,728, filed. October 27, 1908.
It has been noticed in the manufacture of sodium, by means of the electrolysis of fixed 5 caustic soda, that during the carrying out of l trolytic cases where incrustations are formed on the electrodes. It should also be re the process, the quantity of sodium produced nml'ked that, on contrary: ceftam decreases somewhat after a short time. ,This electl'Olytlc Qperatlons and PfiTt1C1lla11y 1n phenomenon cannot be attributed to an inthe P p? of Chloratesfl the fonlmtlon crease i th i ta f th b h or to of deposits on the cathode is considered as favorable to the ellicient working of the operation.
Claims:
1. The herein described process for the manufacture of metallic sodium, which consists in subjecting fused caustic soda to electrolysis, withdrawing the cathode periodically, bringing it into contact with a restorative liquid, and then replacing it for continuing the electrolytic operation.
2. The herein described process for the manufacture of metallic sodium, which consists in subjecting fused the surface of the electrodes. Up till now it 1 has been surmised that the decrease in the production was due to impurities in the caustic soda, silicic acid, iron oxid, etc., l which are contained even in the purest soda, I the proportion of the impurities increasing as the decomposition of the sodais carried out. This supposition was apparently confirmed by the fact that the quantity of sodium produced decreased all the more rapidly when the soda was very impure. nder these COIldltlOIlStllQ disadvantage could only be remedied by taking the electrolytic vat out of circuit. to dismount and clean it, as soon as its eiliciency began to decrease, then refilling it with new caustic soda and putting it to work again. It is easy to imagine the loss of time and the considerable l labor necessitated by such a process; more- 1 over, to obviate the too frequent dismountl ing, and clcansin ODQlRtlOllS,OlllY soda of the. purest grade was used which very expen- 1 sive, and had to be rejected when it had only supplied a small quantity of sodium. The new process does away with these disadvan- I tages and enables sodium to be produced in l l l l I l trolysis, withdraw'ng the cathode periodically, bringing it into contact with water to restore its efficiency, and then replacing; it for continuing the electrolytic operation.
3. The herein described process for the manufacture of metallic sodium, which con sists in subjecting fused caustic soda to electrolysis, withdrawing the cathode when its eiliciency becomes materially diminished, and continuing with a cathode of greater ellicicncy.
