Description

Seefernmeldekabel In dem Patent 5551i7 ist ein Seefernmeldekabel unter Schutz gestellt, dessen Isolation aus Hydrokautschuk mit Beimischungen von Isolierstoffen geringerer Plastizität besteht. Es wurde nun gefunden, daß man die vorzüglichen Eigenschaften eines derartigen Fernmeldekabels noch dadurch verbessern kann, daß man den normalen Hydrokautschuk durch eiweißfreien oder eiweißfrei gemachten Hydrokautschuk ersetzt. Zu diesem Zwecke kann man entweder von gewöhnlichem Kautschuk ausgehen, dem die Eiweißstoffe vor oder nach der Hydrierung entzogen sind, öder man kann hydrierten synthetischen Kautschuk (synthetischen Hydrokautschuk) verwenden, der von vornherein durch seine Herstellung aus reinen stickstofffreien Ausgangsstoffen von Eiweißverbindungen frei ist.Sea telecommunication cable In the patent 5551i7 a sea telecommunication cable is under Protection provided, its insulation made of hydro-rubber with admixtures of insulating materials there is less plasticity. It has now been found that the excellent Properties of such a telecommunication cable can still be improved in that normal hydro-rubber is replaced by protein-free or protein-free hydro-rubber replaced. For this purpose one can either start from ordinary rubber, from which the proteins are withdrawn before or after the hydrogenation, or one can hydrogenate it Use synthetic rubber (synthetic hydro-rubber) from the start through its production from pure nitrogen-free raw materials of protein compounds free is.

Auch die dem Hydrokautschuk beigemischten Stoffe, wie Guttapercha, Balata oder gewöhnlicher Kautschuk, sollen zweckmäßigerweise von ihrem Eiweißgehalt befreit sein.The substances added to the hydro-rubber, such as gutta-percha, Balata, or common rubber, are said to be conveniently based on their protein content be liberated.
