KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. PATENTSCHRIFTPATENT LETTERING M 188567 KLASSE 21 b. GRUPPE- M 188567 CLASS 21 b. GROUP Patentiert im Deutschen Reiche vom 6. Mai 1904 ab.Patented in the German Empire on May 6, 1904. Um das mit einer Abnahme der Kapazität verbundene Sintern negativer Polelektroden, deren wirksame Masse aus Bleiverbindungen besteht, zu verhindern, pflegt man der Masse inerte, fein verteilte Körper, wie z. B. Koks, Gips, Bimsstein u. dgl., beizumischen. Dieses Verfahren ist aber nur anwendbar unter Benutzung besonders gestalteter Masseträger, die einen größeren Raum als gewöhnlicheTo avoid the sintering of negative pole electrodes associated with a decrease in capacitance, the effective mass of which consists of lead compounds is what the masses are used to prevent inert, finely divided bodies, such as B. coke, gypsum, pumice and the like. To be mixed. This However, the method can only be used using specially designed mass carriers, which have a larger space than ordinary ίο Gitterplatten einnehmen.ίο Take the grid plates. Man hat nun vorgeschlagen, der Abnahme der Kapazität durch besondere mit Hohlräumen versehene Holzbrettchen zu begegnen, die zwischen die Elektrodenplatten eingesetzt werden. Solche aus gewöhnlichem Holz hergestellte Brettchen erhöhen aber den inneren Widerstand der Zellen besonders im Anfang außerordentlich. Auch werden die positiven Platten durch unpräparierte Holzbrettchen schnell zerstört. ,It has now been proposed to reduce the capacity by using special cavities to counter provided wooden boards, which are inserted between the electrode plates will. But such boards made of ordinary wood increase the internal The resistance of the cells is extraordinary, especially in the beginning. Also will be the positive Panels quickly destroyed by unprepared wooden boards. , Durch ausgedehnte Versuche ist ferner festgestellt, daß Holzbrettchen, die entweder durch Nitrieren mittels Salpetersäure und Schwefelsäure oder durch Behandlung mit Schweitzerschem Reagens, Alkali, Salzsäure und Alkohol porös gemacht waren, zwar den inneren Widerstand nicht erhöhen, aber ohne irgend einen Einfluß auf die Lebensdauer der negativen Sammlerplatte sind.Extensive experiments have also shown that wooden boards that either by nitration using nitric acid and sulfuric acid or by treatment with Schweitzer's reagent, alkali, hydrochloric acid, and alcohol were made porous, though does not increase the internal resistance, but without any influence on the service life the negative collector plate. Es ist ferner vorgeschlagen worden, die Holzplatten mit Schwefelsäure oder Natronlauge auszukochen, bis die Stärke und die anderen nicht faserigen Bestandteile gelöst sind. Auch solche Platten sind, wie Versuche ergeben haben, auf das Verhalten der negativen Platten ohne Einfluß. Wird das Holz aber lediglich mit alkalischen Flüssigkeiten, z. B. Lösungen von Hydroxyden, Karbonaten, Silikaten oder Boraten der Alkalien derart behandelt, daß nur die im Holze enthaltenen Harze, sowie die organischen Säuren gelöst werden, so erhält man Trennungsplatten, die genügend porös sind, außer- ■ dem aber die bisher völlig unbekannte und nicht vorauszusehende Eigenschaft zeigen, daß in einer mit derartigen Trennungsplatten versehenen Zelle die negativen Platten eine bedeutend längere Zeit ihre volle Kapazität bewahren, als in einer Zelle, die keine oder nach den obigen bekannten Methoden behandelte Trennungsplatten besitzt. Diese Eigenschaft rührt jedenfalls von dem im Holz belassenen Gehalt an Stärke und ähnlichen Stoffen her, die auflockernd auf den Bleischwamm der negativen Platte wirken, während dem Holz die Harze und die für die Lebensdauer der positiven Platte schädlichen Stoffe entzogen sind.It has also been proposed that the wooden panels with sulfuric acid or caustic soda Boil until the starch and other non-fibrous ingredients are dissolved are. Experiments have shown that such plates are also sensitive to the behavior of the negative plates without influence. However, if the wood is only treated with alkaline liquids, z. B. Solutions of hydroxides, carbonates, silicates or borates of alkalis treated in such a way that only the resins contained in the wood, as well as the organic ones Acids are dissolved, so one obtains separation plates that are sufficiently porous, except- ■ but the hitherto completely unknown and unforeseeable property show that in a cell provided with such separation plates, the negative plates are significant Maintain their full capacity longer than in a cell that was not treated or treated according to the above known methods Owns separation plates. This property is due to the starch content and the like left in the wood Substances that loosen up the lead sponge of the negative plate, while the wood contains the resins and the for the life of the positive plate is deprived of harmful substances. Werden die nach diesem Verfahren behandelten Platten aus Holz in einen Sammler eingebaut, dessen Kapazität durch den Betrieb abgenommen hatte, so bemerkt man eine sehr erhebliche Kapazitätszunahme.The panels of wood treated by this process are placed in a collector built in, the capacity of which had decreased due to operation, one notices one very much significant increase in capacity.
