Herstellung jies Kollodiumüberzuges von Glühstrümpfen.Production of this collodion coating of incandescent mantles.

Patentiert im Deutschen Reiche vom 21. November 1917 ab.Patented in the German Empire on November 21, 1917.

Zur Herstellung des Kollodiumüberzuges für Glühstrümpfe kam bisher hauptsächlich Kampfer und Rizinusöl in Frage, durch deren Anwendung eine elastische und zähe Kollodiumüberhätitung ohne Deformierung des feinen hartgeglühten Aschenskelettes erzielt wurde. Durch den völligen Mangel dieser beiden Materialien ist jetzt zur Kriegszeit die Ersatzfiage hochgradig aktuell geworden.So far, the main focus has been on producing the collodion coating for mantles Camphor and castor oil in question, due to their use an elastic and tough collodion overheating was achieved without deforming the fine, hard-annealed ash skeleton. Due to the complete lack of this For both materials, the substitute issue has now become extremely topical during the war.

ίο Der Erfinder hat festgestellt, daß die molekularen Verbindungen von Phthalsäure (Anhydrid) mit einigen aromatischen Verbindungsgruppen, wie Aminoderivaten (Aniline), zweiwertigen Phenolen, Chinonen, auch solchen, die sich von mehrkernigen aromatischen Kohlenwasserstoffen mit kondensierten Kernen ableiten, z. B. Naphtolen (Naphthalingruppe) und sechsgliedrigen heterozyklischen Substanzen (Pyridingruppe), einzeln oder in Komplexen beide Komponenten zu ersetzen vermögen.ίο The inventor has found that the molecular Compounds of phthalic acid (anhydride) with some aromatic compound groups, such as amino derivatives (anilines), divalent Phenols, quinones, even those that differ from polynuclear aromatic hydrocarbons with condensed nuclei derive, e.g. B. Naphtholes (naphthalene group) and six-membered heterocyclic substances (Pyridine group), able to replace both components individually or in complexes.

In gleicher Weise kann auch der Kampfer bei der Zelluloidfabrikation .ersetzt werden.In the same way, camphor can also be replaced in celluloid manufacture.
