Description
Kabel, insbesondere Seekabel Die Feststellung der Lage eines verlegten Kaibiels, insbesondere eines Seekabels, macht oft erhebliche Schwierigkeiten, wenn es überhaupt möglich ist.Cable, especially submarine cable Determining the location of a laid Kaibiels, especially a submarine cable, often cause considerable difficulties, though it is even possible.
Die vorliegende Erfindung erleichtert die Feststellung der Lage von Kabeln dadurch, daß diese in Abständen Einlagen aus Strahlen aussendenden Isotopen von Elementen aufweisen. Diie Einlagen, z. B. in Form von Bleiisotopen oder Isotopen anderer Metalle, sind in Abständen im Kabel angeordnet, und zwar so, daß sie von einem abschirmenden Mantel nicht überdeckt werden. Mit dem Geigerzähtrohr kann die Lage des Kabels somit ohne weiteres aufgenommen werden. Als Isotopen können scalche Elemente in solchen Mengen ohne weiteres verwendet werden, daß über die Oberfläche des Meeres fahrende Schliffe m,it Hilfe des genannten Geigerzählers die Lage feststellen können. Eine Beschädigung von Personen durch die Strahlen ist nicht zu befürchten.The present invention facilitates the determination of the location of Cables in that these deposits of isotopes emitting rays at intervals of elements. The deposits, e.g. B. in the form of lead isotopes or isotopes other metals, are spaced apart in the cable so that they are from are not covered by a shielding jacket. With the Geigerzähtrohr the Position of the cable can thus be recorded without further ado. As isotopes, scalche Elements are readily used in such amounts that over the surface Using the Geiger counter mentioned above to determine the location can. There is no risk of personal injury from the rays.
Es ist zwar bereits bekannt, bei Hochspannungskabeln, die mit Hochdruckmedium gefüllt sind, urdichte Stellen dadurch zu ermitteln, daß man dem unter Druck stehenden Medium radioaktive Substanzen zusetzt, so daß dort, wo Undichtigkeiten vorliegen, diese an Hand von Meßgeräten, wie z. B. Geigerzähler, festgestellt werden können. Bei diesen Kabeln muß die unter Druck stehende Flüssigkeit im Innern des Kabels durch einen abschirmenden Mantel abgedeckt sein; denn wäre dies nicht, ließen sich die undichten Stellen nicht feststellen.It is already known for high-voltage cables that use high-pressure medium are filled, to determine primordial areas by the fact that one is under pressure Medium adds radioactive substances, so that where there are leaks, this on the basis of measuring devices, such as. B. Geiger counter can be determined. With these Cables must have the pressurized liquid inside the cable must be covered by a shielding jacket; because if this were not the leaks could not be determined.
Bei der Erfindung handelt es sich nicht um die Feststellung undichter Stellen des Kabels, sondern um die Kabelartung, so daß die im Kabel befindlichen Isotopen von Elementen nicht von .einer abschirmenden Ummantelung umfaßt werden dürfen.The invention is not about detecting leaks Place the cable, but about the cable type, so that those located in the cable Isotopes of elements are not covered by a shielding sheath to be allowed to.
