Patentiert im Deutschen Reiche vom 25. November 1913 ab. Patented in the German Empire on November 25, 1913.
Bei Förder- und anderen aus einem geschlossenen Leiter mit Stellen wechselnden Widerstandes bestehenden Anlagen ist es bekannt, zur Signalübertragung durch das Leitergebüde den wechselnden Widerstand dadurch nutzbar zu machen, daß man den Empfangsapparat für telegraphische und telephonische Zeichen direkt parallel zu dem veränderlichen Widerstand schaltet und dadurchIn the case of conveyors and others from a closed ladder with places changing Resistance existing systems, it is known for signal transmission through the conductor building to make the changing resistance usable by using the receiving apparatus for telegraphic and telephonic signs directly parallel to the changeable one Resistance switches and thereby
ίο die im Seil fließenden Wechselströme abnimmt. Dieses Verfahren hat mehrere Nachteile: einmal werden die Widerstände im Stromkreis nicht entfernt, sondern nur durch einen ebenfalls im Vergleich zum Seilwiderstand hohen Widerstand enthaltenden Apparat überbrückt, so daß also eine Schwächung des im Seil fließenden Stromes bestehen bleibt, die sich namentlich bei mehreren, an demselben Seil liegenden Empfangsapparaten fühlbar macht, andererseits wird bei einem Verschwinden des Übergangswiderstandes, beispielsweise infolge eines guten Kontaktes zwischen Förderseil und Korb, der den Empfangsapparat durchfließende Teilstrom erheblich vermindert, er kann sogar gänzlich verschwinden, so daß der Zeicüenempfang unsicher und abhängig von der Größe des beeinflußbaren Übergangswiderstandes ist.ίο the alternating currents flowing in the rope decreases. This method has several disadvantages: once there are resistors in the circuit not removed, but only through a high resistance compared to the rope resistance Resistance-containing apparatus bridged, so that a weakening of the rope flowing current, which is particularly common in several, on the same rope on the other hand, if the Transfer resistance, for example as a result of good contact between the hoisting rope and basket, which considerably reduces the partial flow flowing through the receiving apparatus, he can even disappear completely, making the reception of the drawing uncertain and dependent depends on the size of the contact resistance that can be influenced.
Durch die Erfindung werden diese Übelstände dadurch beseitigt, daß ein den Empfangsapparat induktiv beeinflussender Übertragungskörper sowohl unmittelbar mit dem geschlosenen Leitergebilde als auch durch einen die Stellen des veränderlichen Wider-Standes überbrückenden Leiter von geringem Ohmschen Widerstand derart induktiv gekuppelt ist, daß die Induktionswirkung des abgezweigten Stromes auf den Übertragungskörper sich der des Hauptstromes hinzufügt, so daß der schwächende Einfluß des Wider-Standes beseitigt ist.The invention eliminates these inconveniences in that a receiving apparatus inductively influencing transmission body both directly with the closed conductor structure as well as through a ladder bridging the points of the variable resistance Ohmic resistance is inductively coupled so that the induction effect of the branched current on the transmission body is added to that of the main current, so that the weakening influence of the resistance is eliminated.
Auf der Zeichnung zeigt Fig. 1 schematisch eine Ausführungsform der Schaltungsanordnung gemäß der Erfindung bei einem Förderseil mit Förderkorb und Fig. 2 die Einschaltung mehrerer Empfangsapparate in einen derartigen Stromkreis.In the drawing, FIG. 1 shows schematically an embodiment of the circuit arrangement according to the invention in a hoisting rope with cage and Fig. 2, the activation several receivers in such a circuit.
In Fig. ι bezeichnet α das von einer Wechselstromquelle w beeinflußte Förderseil, b den einen veränderlichen Widerstand bildenden Förderkorb, c einen diesen Förderkorb überbrückenden Leiter, der derart um den die Induktion übertragenden Eisenkörper d gewickelt ist, daß die Wirkung des abgezweigten Stromes sich der des Hauptstromes hinzufügt. Es wird auf diese Weise der wechselnde Widerstand des Förderkorbes ausgeglichen und sein schwächender Einfluß dadurch beseitigt, daß bei zunehmendem Widerstand am Korb der Stromfluß in dem Umgehungsleiter c entsprechend verstärkt, bei abnehmendem Widerstand geschwächt wird. Der Empfangsapparat e selbst kann aus diesem Grunde auch einen für sein gutes Arbeiten zweckmäßigen höheren Widerstand erhalten, und seine Wirkung wird gleichförmig und unabhängig von der Größe und Veränderlichkeit des Übergangswiderstandes vom Seil zum Korb.In Fig. Ι α denotes the conveyor rope influenced by an alternating current source w , b the conveyor cage forming a variable resistance, c a conductor bridging this conveyor cage, which is wound around the induction-transmitting iron body d in such a way that the effect of the branched off current is that of the Main stream. In this way, the changing resistance of the conveyor cage is compensated for and its weakening influence is eliminated in that the current flow in the bypass conductor c is correspondingly increased with increasing resistance at the cage, and is weakened with decreasing resistance. For this reason, the receiving apparatus itself can also receive a higher resistance which is appropriate for its good functioning, and its effect becomes uniform and independent of the size and variability of the transition resistance from the rope to the basket.
In Fig. 2 sind die Empfangsapparate in gleicher Weise in einen Stromkreis eingeschaltet wie der Apparat nach Fig. 1. Das neueIn Fig. 2, the receiving sets are switched on in the same way in a circuit like the apparatus according to Fig. 1. The new one
Verfahren eignet sich besonders für die Einschaltung mehrere Empfangsapparate in einen Stromkreis, weil infolge des niedrigen Widerstandes der Überbrückung der Gesamtstrom im Seil durch den Eigenwiderstand der Empfangsapparate nicht wesentlich geschwächt und auch nicht durch den veränderlichen Übergangswiderstand beeinflußt wird.This method is particularly suitable for switching on several receivers into one Circuit, because as a result of the low bridging resistance, the total current not significantly weakened in the rope by the inherent resistance of the receiving apparatus and is also not influenced by the variable contact resistance.
