PATENTAMT.PATENT OFFICE.
Es sind Anordnungen bekannt, bei denen eine Thermosäule durch verbrennende Schlagwetter geheizt wird und deren Strom auf Meßinstrumente, Relais u. dgl. einwirkt. Gegenstand der Erfindung ist die Anwendung einer Thermosäule zur Beeinflussung eines oder mehrerer Stromkreise, welche Glühlampen oder elektrisch glühende Drähte enthalten.Arrangements are known in which a thermopile by burning fire weather is heated and its current acts on measuring instruments, relays and the like. object the invention is the use of a thermopile to influence one or more circuits, which incandescent lamps or contain electrically glowing wires.
Fig. ι der Zeichnung zeigt die Schalt ungsweise einer Ausführungsform der Erfindung, Fig. 2 den Vertikalschnitt durch die Thermosäule samt Zündvorrichtung. Die Thermosäule t ist kreisförmig angeordnet mit radial gerichteten Heizpolen h, an denen die Schlagwetter vorbeistreichen, die durch die ständig glühende Platinspirale p gezündet werden. Die Elemente oder Batterien b1 b2 sind mit den Glühlampen I1I2 in Reihe geschaltet. An den Anschlußpunkten ax a2 liegen die Pole der Thermosäule t. Damit die Glühlampen Z1 I2 gleichmäßig leuchten, ist ein kleiner Widerstand w der Lampe I2 vorgeschaltet, welcher die durch die Thermosäule erzeugte zusätzliche Spannung so lange vernichtet, als die Säule nur durch die Heizspirale p, nicht aber durch die Verbrennung der Grubengase erwärmt wird.Fig. Ι of the drawing shows the switching mode of an embodiment of the invention, Fig. 2 shows the vertical section through the thermopile including the ignition device. The thermopile t is arranged in a circle with radially directed heating poles h, which are passed by the firedamp, which is ignited by the constantly glowing platinum spiral p. The elements or batteries b 1 b 2 are connected in series with the incandescent lamps I 1 I 2. The poles of the thermopile t are at the connection points a x a 2. So that the incandescent lamps Z 1 I 2 shine evenly, a small resistor w is connected upstream of the lamp I 2 , which destroys the additional voltage generated by the thermopile as long as the column is only heated by the heating coil p, but not by the combustion of the mine gases will.
Treten nun Grubengase durch die Thermosäule, so verbrennen sie an der Heizspirale p
und beheizen die Heizpole h, so daß die Leistung der Thermosäule ansteigt. Der Strom
der Thermosäule wirkt im Stromkreis I2
additiv, im Stromkreis I1 subtraktiv, so daß
die beiden Lampen eine verschiedene Helligkeit zeigen, die noch durch besondere optische
Hilfsmittel meßbar gemacht werden kann.
Durch die gekennzeichnete Schaltung wird es ermöglicht, mit verhältnismäßig geringen
Leistungen der Thermosäule große Einwirkungen zu erzielen. Um den Einfluß der Heizspirale
p möglichst zu beseitigen, kann die ständige Zündung der Grubengase auch durch
eine elektrische Funkenstrecke erfolgen, die zwar hohe Temperaturen erzeugt, jedoch geringe
Wärmemengen. In diesem Falle würde der Widerstand w überflüssig sein, da durch
die Funkenstrecke keine nennenswerte Erhitzung der Thermosäule stattfindet.If mine gases now pass through the thermopile, they burn on the heating coil p and heat the heating poles h, so that the output of the thermopile increases. The current of the thermopile has an additive effect in the circuit I 2 and subtractively in the circuit I 1 , so that the two lamps show a different brightness, which can be made measurable by special optical aids.
The marked circuit makes it possible to achieve large effects with relatively low power of the thermopile. In order to eliminate the influence of the heating coil p as far as possible, the constant ignition of the mine gases can also be carried out by an electrical spark gap, which generates high temperatures but low amounts of heat. In this case the resistor w would be superfluous, since the spark gap does not cause any significant heating of the thermopile.
Die beschriebene Einrichtung kann mit einer elektrischen Sicherheitslampe kombiniert werden, bei der zwei Primär- oder Sekundärelemente Verwendung finden. Die Zündung der Grubengase kann dauernd erfolgen oder nach Bedarf von Zeit zu Zeit zum Zwecke der Prüfung auf Methan.The device described can be combined with an electrical safety lamp where two primary or secondary elements are used. The ignition the mine gases can be carried out continuously or as required from time to time for the purpose testing for methane.
Selbstverständlich ist es auch angängig die Thermosäule in den Stromkreis einer einzigen Lampe zu schalten, welch letztere dann bei Anwesenheit von Grubengas an Helligkeit zu- oder abnimmt, je nachdem die Säule der Betriebsstromquelle vor- oder gegengeschaltet ist.Of course, the thermopile is also accessible in the circuit of a single one To switch the lamp, which then switches on the brightness in the presence of mine gas. or decreases, depending on the operating power source column is upstream or downstream.
