Description
Im Patent 498414 ist eine Einrichtung zur Signalübertragung unter Verwendung von Wechselströmen auf fahrende Lokomotiven beschrieben, deren wesentliches Kennzeichen darin besteht, daß zwei Sendefrequenzen zwecks Verbreiterung der Resonanzkurve verwandt werden, um eine von innerhalb des Schwankens der Betriebsfrequenz unabhängige und praktisch genügende Betriebssicherheit zu erzielen. Das dort beschriebene Verfahren hat jedoch insbesondere bei Verwendung von Frequenzen unter 1500 pro Sekunde den Nachteil, daß die auftretenden Schwebungen, bedingt durch die Verschiedenheit der beiden Frequenzen, zu langsam sind und somit ein Ansprechen des Betriebsrelais hervorrufen. In patent 498414 there is a device for signal transmission using Alternating currents on moving locomotives described, their essential characteristics therein consists that two transmission frequencies are used for the purpose of broadening the resonance curve, an independent and practical one from within the fluctuation of the operating frequency to achieve sufficient operational safety. However, the method described there has in particular when using frequencies below 1500 per second the disadvantage that the occurring Beats too slow due to the difference between the two frequencies and thus cause the operating relay to respond.
Die vorliegende Erfindung gibt nun eine Einrichtung an, wodurch dieser Nachteil beseitigt wird und wodurch es ermöglicht wird, auch Frequenzen unter einer bestimmten Grenze, von der ab die auftretenden Schwebungen ein Ansprechen des Relais und damit eine Störung der Betriebssicherheit ergeben würden, verwendet werden können. Gemäß der vorliegenden Erfindung werden dieStröme derbeidenBetriebsfrequenzen in elektrisch sowie vorzugsweise auch magnetisch getrennte Stromkreise geleitet und nur zu einer gemeinsamen Einwirkung auf das Sicherungsrelais verwandt. Es werden also nur die mechanischen Einwirkungen beider Betriebsfrequenzen auf das Relais ausgenutzt, während dieselben in elektrischer sowie vorzugsweise auch magnetischer Hinsicht vollständig voneinander unabhängig bleiben, so daß auf dem Auftreten von Schwebungen beruhende Nachteile dadurch ausgeschaltet werden.The present invention now provides a device whereby this disadvantage overcomes and which makes it possible to use frequencies below a certain limit, from which the occurring beats trigger the relay and thus a malfunction the operational safety would result, can be used. According to the present In the invention, the currents of the two operating frequencies are electrical as well as preferably also magnetically separated circuits and only to a common effect related to the fuse relay. So there will only be the mechanical effects both operating frequencies are used on the relay, while the same is used in electrical as well preferably remain completely independent of each other also from a magnetic point of view, so that disadvantages based on the occurrence of beats are thereby eliminated will.
Durch die beiliegenden Abbildungen wird das Wesen des Erfindungsgegenstandes an Hand einer praktischen beispielsweisen Ausführung noch näher erläutert. Es bedeuten in Abb. 1 G1 und G2 die beiden Mittelfrequenzgeneratoren, die mittels je eines in Serie angeordneten Kondensators C1 bzw. C2 sowie je einer der beiden Wicklungen W1 und W2 des gemeinsamen Sicherungsrelais R sowie ferner je einer Spule Ai1 bzw. M2 das Schienenmagneten auf Resonanz abgestimmt sind. Wie ersichtlich, bilden die einzelnen Maschinenkreise vollkommen getrennte Abstimmkreise, während nur die mechanischen Anzugskräfte der beiden Relaiswicklungen auf den gemeinsamen Anker des Relais sich vereinigen. Mann kann sogar noch so weit gehen, auch die beiden Kreise magnetischThe nature of the subject matter of the invention is explained in more detail by means of a practical exemplary embodiment by means of the accompanying figures. In Fig. 1, G 1 and G 2 denote the two medium-frequency generators, each of which is powered by a series-arranged capacitor C 1 or C 2 and one of the two windings W 1 and W 2 of the common safety relay R and also a coil Ai 1 or M 2 the rail magnets are tuned to resonance. As can be seen, the individual machine circuits form completely separate tuning circuits, while only the mechanical attraction forces of the two relay windings combine on the common armature of the relay. You can go so far, even the two circles magnetically

vollkommen voneinander zu trennen. Dies erweist sich jedoch praktisch nicht immer als unbedingt erforderlich, da die beiden Kreise auf verschiedene Frequenzen abgestimmt sind und daher eine Rückwirkung des Kreises auf den anderen durch die gegenseitige Kopplang der beiden Spulen M1 und M2 in praktisch unbedeutenden Grenzen gehalten werden kann. Letzteres hängt wiederum von der Differenzcompletely separate from each other. However, this turns out to be practically not always absolutely necessary, since the two circuits are tuned to different frequencies and therefore a reaction of the circuit on the other can be kept within practically insignificant limits due to the mutual coupling length of the two coils M 1 and M 2. The latter in turn depends on the difference

In Abb. 2 ist schematisch ein Beispiel für einen magnetisch sowie elektrisch getrennten Schienenmagneten gegeben, und zwar zeigt Abb. 2a eine Ansicht und Abb. 2b eine entsprechende Draufsicht. Der Schienenmagnet besteht aus zwei Teilen, und zwar aus einem Teil A mit niedrigen Polschuhen und aus einem Teil B mit höheren Polschuhen. Durch die verschiedene Höhe der Polschuhe erreicht man eine Unterbringung zweier elektrisch sowie magnetisch getrennter Wicklungen. Beide MaIn Fig. 2 an example of a magnetically and electrically separated rail magnet is given, namely Fig. 2a shows a view and Fig. 2b shows a corresponding plan view. The rail magnet consists of two parts, namely part A with low pole pieces and part B with higher pole pieces. Due to the different heights of the pole shoes, two electrically and magnetically separated windings can be accommodated. Both Ma
