 Kontakt hat, an seiner Stelle gehalten, und zwar von eisernen Hnltcrn, die auf einem auf dem   13Behälter   a aufgesetzten Deckel mit grosser   zentraler Onung ruhen. Diese Einzelheiten,   die nichts Eigentümliches bieten, sind ebenso wie sonstige selbstverständliche Details, wie elektrische Heizvorrichtung und anderes, in der Zeichnung nicht dargestellt. Der Sammler bewirkt rasch das Zusammenfliessen der aufsteigenden   Metnl1kUgelchell   in einen engen Raum und vormindert auf diese Weise Verluste durch   Wiederauflösen   in dem   Schmelzbade.   



   Durch die vorliegende Anordnung werden eine Mehrausbeute an Natrium, eine lange Haltbarkeit der Anode und ein grösserer Wirkungsgrad der Vorrichtung bei gleicher Rauminanspruchnahme erzielt. Form und Umfang der beschriebenen Details können den jeweiligen Verhältnissen entsprechend innerhalb gewisser Grenzen variieren. 



   PATENT-ANSPRÜCHE :   t.   Vorrichtung zur Darstellung von metallischem Natrium durch Elektrolyse von feuer-   nüssigem   Ätznatron, gekennzeichnet durch eine aus zwei konzentrischen miteinander elektrisch verbundenen Zylindern bestehende Anode, zwischen denen sich die Kathode mit darüber unabhängig von ihr angeordnetem Sammler befindet.

 Contact has held in its place, namely by iron handles that rest on a lid with a large central onung placed on the container a. These details, which offer nothing unique, are not shown in the drawing, as are other obvious details such as electrical heating devices and others. The collector quickly causes the rising metals to flow together in a narrow space and in this way prevents losses due to redissolving in the molten bath.



   The present arrangement achieves a higher yield of sodium, a long service life of the anode and a greater degree of efficiency of the device with the same space requirement. The form and scope of the details described can vary within certain limits according to the respective circumstances.



   PATENT CLAIMS: t. Device for the production of metallic sodium by electrolysis of fiery caustic soda, characterized by an anode consisting of two concentric cylinders electrically connected to one another, between which the cathode is located with a collector arranged above it independently.

Claims

2. Device according to claim l, characterized in that the electrical and mechanical connection of the two cylinders forming the anode is made by two brackets which, in order to remove them from the electrolytic effect as much as possible, are attached below the cylinder.

3. Apparatus according to claim 1 with a collector for the metallic sodium and a pot for withdrawing the sodium formed, characterized in that this collector is designed as a narrow, annular, downwardly directed channel in the form of a cuff which covers the cathode and above the gap of the two anode cylinders, but is dimensioned narrower than this gap.

4. Apparatus according to claim L, characterized in that the cathode is suspended with the help of two perpendicular arms that conduct electricity at the same time, which are passed through the collector, EMI2.2
