Zusatz zum Patent 240751 vom 4. Juli 1908.Addendum to patent 240751 of July 4, 1908.

Patentiert im Deutschen Reiche vom 26. März 1909 ab. Längste Dauer: 3. Juli 1923.Patented in the German Empire on March 26, 1909. Longest duration: July 3, 1923.

Im Hauptpatent 240751 ist ein Verfahren zur Herstellung für die Gewinnung von Kunstfäden und ähnlichen Gebilden geeigneter Lösungen beschrieben, das darin besteht, daß man Nitro- und . Acetylcellulose gemeinsam in Acetylentetrachlorid - Acetongemischen löst oder Lösungen von Acetylcellulose in Acetylentetrachlorid und von Nitrocellulose in Aceton miteinander mischt. Bei weiterer Ausarbeitung der Erfindung wurde nun festgestellt, daß zu dem gleichen Zwecke, d. h. zwecks Gewinnung homogener, Acetyl- und Nitrocellulose gleichzeitig enthaltender Lösungen das Acetylentetrachlorid durch Chloroform und das Aceton durch Essigester ersetzt werden können.In the main patent 240751 is a process for the production for the extraction of Artificial threads and similar structures of suitable solutions described, which consists in that one nitro and. Acetyl cellulose together in acetylene tetrachloride - acetone mixtures dissolves or solutions of acetyl cellulose in acetylene tetrachloride and of nitrocellulose mixed together in acetone. In further elaboration of the invention was now found that for the same purpose, i. H. for the purpose of obtaining homogeneous, acetyl and solutions containing nitrocellulose simultaneously with acetylene tetrachloride Chloroform and the acetone can be replaced by ethyl acetate.
