Verfahren zur Herstellung von Glühstrümpfen.
Bei der Glühkörperfabrikation wurde bisher zum Auswaschen der mit Säuren und gegebenenfalls hinterher mit Ammoniak behandelten Rohschläuche destilliertes Wasser benutzt.
Es hat sich nun gezeigt, dass statt destillierten Wassers für diese Zwecke Wasser genügt, das von den Salzen der schweren Metalle, der Erdmetalle und alkalischen Erden befreit ist, jedoch Salze der Alkalimetalle enthalten kann.
Der Gehalt an Salzen der Alkalimetalle kann in dem Wasser verbleiben, weil diese Salze sich bei der hohen Temperatur, welcher der Glühkörper schliesslich ausgesetzt wird, verflÜchtigen.
Diesen Anforderungen entspricht z. 13. ein möglichst weitgehend enthärtetes Leitungwasser. Als besonders geeignet hat sich ein mit Aluminatsilikat (Permutit) gereinigtes Wasser gezeigt.
PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Glühstrümpfen, dadurch gekennzeichnet, dass zum Waschen der Rohschläuche ein bis auf die Salze der Alkalien von allen nicht flüchtigen anorganischen Salzen befreites Wasser verwendet wird.

Process for manufacturing incandescent mantles.
In the manufacture of incandescent bodies, distilled water was previously used to wash the raw hoses treated with acids and, if necessary, with ammonia afterwards.
It has now been shown that instead of distilled water, water that has been freed from the salts of heavy metals, earth metals and alkaline earths, but can contain salts of alkali metals, is sufficient for these purposes.
The content of salts of the alkali metals can remain in the water, because these salts volatilize at the high temperature to which the incandescent body is finally exposed.
These requirements meet z. 13. tap water that has been softened as much as possible. Water purified with aluminate silicate (permutite) has proven to be particularly suitable.
PATENT CLAIMS:
1. A process for the production of incandescent mantles, characterized in that a water freed from all non-volatile inorganic salts except for the salts of the alkalis is used for washing the raw hoses.
