Patentanspruch:Claim: Anordnung gegen unbefugtes Aufheben der Schutz wirkung bei Sicherungen von Tresoren oder sonstigen Räumen, welche von einem unter Diackluft gesetzten schmiedeeisernen Röhrennetz umgeben werden, das bei einem Durchbohren o. dgl. die Druckluft entweichen und mittels auf den Druckabfall wirkenden Kontaktmanometers o. dgl. Alarmvorrichtungen ansprechen läßt, gekennzeichnet durch im Innern der Rohre (ö) lose eingelegte, massiv gußeiserne, rippenartig gestaltete Profilstäbe' (/), die ein stellenweises Zusammenpressen und Zusammenschweißen der Rohre und streckenweises Abtrennen des Röhrennetzes verhindern.Arrangement against unauthorized lifting of the protective effect for fuses of Safes or other rooms, which are set by a Diackluft Wrought iron pipe network are surrounded, which escape when drilling or the like. The compressed air and by means of the pressure drop acting contact manometer or similar alarm devices respond can, characterized by loosely inserted inside the tubes (ö), solid cast-iron, rib-like shaped profile rods' (/), which are pressed together in places and prevent the pipes from being welded together and the pipe network from being severed in sections.
