  Bleimantelloses Kabel. 



   Im   Stammpatent Nr.   102187 ist ein Verfahren zur Herstellung eines   bleimantellosen     Kabels   beschrieben, nach welchem zum Schütze der Papierisolation des   Eabelkernes   gegen Luft-und Wasserzutritt und gleichzeitig zum Schutze des   äusseren Mantels aus Bitumen, Gummi od. dgl. gegen   die Ein-   wirkung der Tränkmasse   der Isolation des Kabelkernes eine Zwischenschicht aus elastischen Zelluloseestern oder Zelluloseäthern zwischen Kabelkern und äusseren Mantel eingeschaltet ist. 



   Diese Zwischenschicht kann nach vorliegender Erfindung vorteilhaft durch reine Zellulose oder Hydrozellulose (Zellophan) ersetzt werden. Diese kann entweder in Form von Bändern (Filmen), wie sie durch Fällung aus Zelluloselösungen erzengt werden, Verwendung finden, oder sie kann aus   Bändern   
 EMI1.1 
 Papier oder Gewebestreifen abgedichtet werden. 



   Ferner kann diese Zwischenschicht auch aus oxydierten trocknenden Ölen oder aus   Kunstharzen   bestehen. Diese Massen können ebenfalls auf Bänder aufgetragen und in dieser Form um die Kabelseele gelegt werden. Die trocknenden Öle müssen nach der   Imprägnierung   der Bänder durch   Oxydation unlöslich   gemacht bzw. in linoxynartige Massen übergeführt werden. Die Kunstharze sind in die unlösliche und unschmelzbare C-Form überzuführen. 



     PATENT-ANSPR#CHE   :   l.   Bleimantelloses Kabel mit getränkter Papierisolation nach dem Stammpatent Nr. 102187, bei dem zum Schutze des Kabelkernes gegen Luft- und Wasserzutritt und gleichzeitig zum Schutze des   äusseren Mantels   aus Bitumen, Gummi od. dgl. gegen die Einwirkung der Tränkmasse des Kabelkernes eine Zwischenschicht eingeschaltet ist, dadurch gekennzeichnet, dass diese Zwischenschicht aus Lösungen   gefällter   Zellulose oder Hydrozellulose besteht.

  Lead-sheathed cable.



   The parent patent no. 102187 describes a process for the production of a lead-free cable, according to which to protect the paper insulation of the label core against the ingress of air and water and at the same time to protect the outer jacket made of bitumen, rubber or the like against the effects of the impregnating compound The insulation of the cable core has an intermediate layer made of elastic cellulose esters or cellulose ethers between the cable core and the outer jacket.



   According to the present invention, this intermediate layer can advantageously be replaced by pure cellulose or hydrocellulose (cellophane). This can be used either in the form of tapes (films), as they are produced by precipitation from cellulose solutions, or it can be made from tapes
 EMI1.1
 Paper or strips of fabric can be sealed.



   Furthermore, this intermediate layer can also consist of oxidized drying oils or synthetic resins. These masses can also be applied to tapes and placed around the cable core in this form. After the tapes have been impregnated, the drying oils must be made insoluble by oxidation or converted into linoxyn-like masses. The synthetic resins must be converted into the insoluble and infusible C-form.



     PATENT CLAIMS: l. Lead-sheathed cable with impregnated paper insulation according to the parent patent no. 102187, in which an intermediate layer is inserted to protect the cable core against the ingress of air and water and at the same time to protect the outer sheath made of bitumen, rubber or the like against the effects of the impregnating mass of the cable core, characterized in that this intermediate layer consists of solutions of precipitated cellulose or hydrocellulose.
