Description
Patentiert im Deutschen Reiche vom 12. September 1907 ab. Patented in the German Empire on September 12, 1907.
Es ist bekannt, für die mit unendlich großem Anfangswiderstand arbeitenden Fritter als Elektrodenmaterial Stahl, Messing o. dgl. zu benutzen. Es ist auch vorgeschlagen worden, die eine Elektrode und das Füllpulver aus einem nicht . oxydierbaren Edelmetall herzustellen. Diese Anordnung hat jedoch den Nachteil, daß sich infolge des geringen Härtegrades, den reine Edelmetalle besitzen, eineIt is known for the fritter working with an infinitely large initial resistance as To use electrode material steel, brass or the like. It has also been suggested the one electrode and the filling powder from one not. to produce oxidizable precious metal. However, this arrangement has the disadvantage that due to the low degree of hardness, possessed by pure precious metals, a
ίο Hochglanzpolitur entweder überhaupt nicht herstellen ließ oder, wenn sie anfangs vorhanden war, bald durch die Benutzung des Fritters zerstört wurde.ίο High gloss polish either, not at all or, if it was initially available, soon by using the fritter was destroyed.
Dieser Nachteil wird durch den Gegenstand der vorliegenden Erfindung beseitigt, welcher in einem mit unendlich großem Anfangswiderstande arbeitenden Fritter besteht, bei welchem die eine Elektrode und das Füllmaterial aus der Legierung oder Mischung eines edlen mit einem unedlen Metall besteht, beispielsweise Silber mit Kupfer oder Kupfer mit Gold, und die andere Elektrode aus Magnalium hergestellt ist. Ein derartiger Fritter besitzt gegenüber den bisher bekannten Ausführungsformen nicht nur eine erheblich größere Empfindlichkeit, sondern es ist auch die Betriebssicherheit wesentlich vergrößert, indem die hochglanzpolierten Elektroden und gegebenenfalls auch das Füllpulver bei Anwendung der richtigen Metallegierung oder Mischung seine oberflächliehe Beschaffenheit bei der Benutzung des Fritters nicht wesentlich verändert, so daß die Empfindlichkeit des Fritters stets dieselbe bleibt. ■This disadvantage is eliminated by the subject matter of the present invention, which is disclosed in a fritter working with an infinitely large initial resistance, in which the an electrode and the filler material from the alloy or mixture of a noble with a base metal, for example silver with copper or copper with gold, and the other electrode is made of magnesium. Such a fritter has opposite the previously known embodiments not only have a significantly greater sensitivity, but it is also the operational safety significantly increased by the highly polished Electrodes and possibly also the filling powder when using the correct metal alloy or mixture its superficial Condition when using the fritter not significantly changed, so that the sensitivity of the fritter always remains the same. ■
