PATENT-ANSPRÜCHE : 1. Eine Ausführungsform des Verfahrens gemäss Stammpatent Nr. 5690 zur Überführung von Holz, Sägespänen und anderen cellulosehaltigen Materialien in Zucker (Dex- trose), dadurch gekennzeichnet, dass die Invertierung durch vereinigte Einwirkung von Schwefeldioxyd und Schwefelsäureanhydrid bewirkt wird. PATENT CLAIMS: 1. An embodiment of the process according to parent patent no. 5690 for converting wood, sawdust and other cellulose-containing materials into sugar (dex- trose), characterized in that the inversion is brought about by the combined action of sulfur dioxide and sulfuric anhydride. 2. Eine Ausgestattung dos Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass die Invertierung lediglich mit Hilfe von Schwefelsäuteanhydrid bewirkt wird. 2. An equipment dos method according to claim 1, characterized in that the inversion is effected only with the aid of sulfuric anhydride. 3. Eine weitere Ausgestaltung des Verfahrens nach Anspruch 1 und 2, dadurch gekennzeichnet, dass man die Einwirkung von Schwefelsäureanhydrid, bezw. des Gemisches desselben mit Schwefoldioxyd durch Erhitzen auf 1000 C. bewirkt. 3. A further embodiment of the method according to claim 1 and 2, characterized in that the action of sulfuric anhydride, respectively. the mixture of the same with sulfur dioxide by heating to 1000 C. 4. Eine weitere Ausgestaltung des Verfahrens nach Anspruch 1 und 2, dadurch gekennzeichnet, dass man nach erfolgter Einwirkung von Schwefelsäureanhydrid, bezw. eines Gemisches desselben mit Schwefeligsäureanhydrid dle Masse in geschlossenen Gefässen weiter auf ca. 1250 C. erhitzt, dann das Reactionsproduct auslaugt und wie in 1 weiter behandelt. 4. Another embodiment of the method according to claim 1 and 2, characterized in that after the action of sulfuric anhydride, respectively. a mixture of the same with sulphurous anhydride, the mass is heated further in closed vessels to about 1250 ° C., then the reaction product is leached out and treated further as in 1.
