KAISERLICHESIMPERIAL

PATENTAMTPATENT OFFICE

Um die Wirksamkeit der elektrischen Sammler zu erhöhen, wendet der Erfinder die Verbindungen des Calciums mit Blei an, besonders wegen der Leichtigkeit, mit welcher ihre Oxydation und Reduction stattfindet.In order to increase the effectiveness of the electrical collectors, the inventor applies the connections of calcium with lead, especially because of the ease with which its oxidation and reduction takes place.

Die Verbindung CaPb Oi hat bei 68 pCt. Bleisuperoxyd 4,56 pCt. activen Sauerstoff. Aufser diesem und bleisaurem Kalk lassen sich natürlich auch die entsprechenden Verbindungen des Bariums und des Strontiums verwenden.The compound CaPb O i has at 68 pCt. Lead peroxide 4.56 pCt. active oxygen. In addition to this and lead acid lime, the corresponding compounds of barium and strontium can of course also be used.

Der in der Verbindung Ca Pb O4 befindliche Kalk besitzt aufser seinen oben erwähnten Eigenschaften noch die Fähigkeit, der Füllmasse bei grofser Porosität bedeutende Festigkeit zu verleihen, so dafs ein Herausfallen der Füllmasse vermieden wird. Die Kalkverbindungen vertreten im Sammler die durchlässige Zelle; man könnte ihre Wirkung mit der des häufig zur Bindung angewendeten Collodiums vergleichen, welches, auch selbst Isolator, den Wirkungsgrad der Vorrichtungen nur wenig beeinflusst.The lime contained in the compound Ca Pb O 4 has, in addition to its properties mentioned above, the ability to give the filling compound considerable strength with a large porosity, so that the filling compound is prevented from falling out. The lime compounds represent the permeable cell in the collector; one could compare their effect with that of the collodium, which is often used for binding, which, also itself an insulator, has little effect on the efficiency of the devices.

Aufser oben angeführten Verbindungen des Kalks mit Blei können auch als Füllstoffe die dem Erfinder patentirten Chrom- und Wolframverbindungen angewendet werden.In addition to the compounds of lime and lead listed above, the Chromium and tungsten compounds patented by the inventor are used.

Auch empfiehlt es sich, die negativen Elektroden aus oben genannten blei- und chromsauren Verbindungen herzustellen, da häufig eine Umpolarisation veranlafst, dafs die negativen Elektroden zu positiven werden und umgekehrt, die grofse Porosität aufserdem auch die Wasserstoffaufnahme in erhöhtem Mafse gestattet.It is also advisable to use the negative electrodes from the above-mentioned lead and chromic acids Establish connections, since polarization often causes the negative Electrodes become positive and vice versa, as does the large porosity the uptake of hydrogen is permitted to an increased extent.
