Sendeeinrichtung für elektrische Wellen im Erdinnern.
Das Problem, den Ausbreitungsvorgang der elektrischen Wellen mittels Antennen, die in Bohrlöcher eingeführt sind, ins Erdinnere zu verlegen bzw. innerhalb eines Grubenbaues in ähnlicher Weise eine Antenne anzuordnen, stösst da auf Schwierigkeiten, wo es sich darum handelt, eine vom Anfangspunkt der Antenne bzw. des Bohrrohres weiter fortliegende feuchte Schicht, die zu Isolationsstörungen Veranlassung gibt, mit der Schwingung zu durchsetzen. Erregt man die Antenne in der gebräuchlichen Form, so liegt zumeist, in Anbetracht der gün : ; tigen Strahlung, der Spannungsknoten in der Nähe der Funkenstrecke, an Erde oder bei einem symmetrischen System in der Mitte des Systems, jedenfalls also zu Tage, wenn beispielsweise das Problem einer Ferntelegraphie durch das Erdinnere zu lösen ist.
Dadurch, dass sich die Grundwasserschicht unter Umständen 100 1n und mehr von dem Spannungsknoten entfernt befindet, geht wegen der Unmöglichkeit einer Isolation die ganze Energie in die Grundwassernäche hinein und kommt nicht mehr durch das unterhalb derselben sitzende Stück der Antenne zur Ausstrahlung. Es gibt nun zwei Wege, die Ausstrahlung doch zu ermöglichen.Der erste läuft, darauf hinaus, künstlich eine Isolation zu schaffen, und zwar durch Ausfrieren der an der Antenne benachbarten Partion des Grundwassers. Dies bildet den Gegenstand des deutschen Patentes Nr. 270400. Der zweite Weg ist der, dass man z.

Transmission device for electric waves in the interior of the earth.
The problem of moving the propagation process of the electrical waves by means of antennas that are inserted into boreholes into the interior of the earth or arranging an antenna in a similar way within a pit, encounters difficulties where it is a matter of one from the starting point of the antenna or . of the drill pipe, which is still lying on the ground and causes insulation disturbances, to penetrate with the vibration. If you excite the antenna in the usual form, then, in view of the gün:; term radiation, the voltage node near the spark gap, on earth or in the case of a symmetrical system in the middle of the system, at least in days when, for example, the problem of remote telegraphy through the interior of the earth has to be solved.
Due to the fact that the groundwater layer is possibly 100 1n and more away from the voltage node, all the energy goes into the groundwater surface due to the impossibility of isolation and is no longer transmitted through the part of the antenna below it. There are two ways of making the broadcast possible. The first is to artificially create insulation by freezing out the part of the groundwater adjacent to the antenna. This forms the subject of German patent no. 270400. The second way is that one z.
B. by switching on a variable capacitor in the radiating half of the antenna circuit shortens the wavelength and shifts the voltage node into the groundwater layer. This will do in most cases
EMI1.1
practical experiments have shown that the radiation of the greatest part of the energy is possible again.
