  Verfahren zur Herstellung gefärbter oder entfärbter wasserdichter plastischer
Massen aus Blut. 



   Gegenstand des Stamm-Patentes Nr. 29281 ist ein Verfahren zur Herstellung plastischer Massen aus Blut durch Behandlung mit   Aluminiumhydroxyd.   Es zeigte sich aber,   dass   das darnach hergestellte Produkt einen nach jeder Richtung hin vollständigen Ersatz für Zelluloid nicht bietet, weil   für manche Zwecke grössere Anforderungen   in bezug auf Festigkeit bzw. Härte gestellt werden.

   Nun wurde gefunden, dass man ein dem Zelluloid an Festigkeit

 bei dem im Stamm-Patente Nr.   29 :) 81 geschützten Verfahren   verwendete Aluminiumhydroxyd ganz oder teilweise   durch   Zelluloseazetat oder durch Nitrozellulose oder durch deren Derivate, wie solche in der Zelluloidfabrikation verwendet werden, ersetzt : in den beiden letzteren Fällen werden jedoch leichter brennbare Produkte erhalten.

 werden in einer hydraulischen Presse zu einem Blocke vereinigt, der dann in   beliebig   dicke Blätter geschnitten werden kann.

 des Durcharbeitens der Masse in der Walzenpresse zugesetzt. 



   Das gut zusammengepresste Gemenge von Blut und Zelluloseazetat bzw.   @itrozellulose-   derivat wird nun in eine Lösung von etwa 10 kg Hexamethylentetramin in Alkohol oder

  Process for making colored or decolored waterproof plastic
Masses of blood.



   The subject of parent patent no. 29281 is a process for the production of plastic masses from blood by treatment with aluminum hydroxide. It turned out, however, that the product manufactured in this way does not offer a complete replacement for celluloid in every direction, because for some purposes greater demands are made with regard to strength or hardness.

   It has now been found that celluloid is more firm
 EMI1.1
 In the process protected in the parent patents No. 29 :) 81, aluminum hydroxide is wholly or partially replaced by cellulose acetate or by nitrocellulose or by their derivatives, such as those used in celluloid manufacture: in the latter two cases, however, more easily flammable products are obtained .
 EMI1.2
 are combined in a hydraulic press to form a block, which can then be cut into sheets of any thickness.
 EMI1.3
 added to working through the mass in the roller press.



   The well-compressed mixture of blood and cellulose acetate or @ itrocellulose derivative is now in a solution of about 10 kg of hexamethylenetetramine in alcohol or
 EMI1.4
 use the same 802-O2 connections.
