angeordneten nichtleitenden Schicht.arranged non-conductive layer.

Patentiert im Deutschen Reiche vom 26. Oktober 1913 ab.Patented in the German Empire on October 26, 1913.

Die Erfindung bezieht sich auf einen Widerstand für in Reihenschaltung angeordnete elektrische Glühlampen, welcher jeder Lampe einer Lampenreihe parallel geschaltet ist. Der Widerstand besteht aus Papier oder einem ähnlichen Nichtleiter, welcher einseitig mit einer Schicht eines schlechten Leiters überzogen und von der Schichtseite aus durchstochen wird, so daß der den Wänden der Durchstechung folgende schlechte Leiter eine Verbindung zwischen zu beiden Seiten des Widerstands angeordneten Leitern herstellen kann. Man erhält so eine schwach leitende Verbindung, welche einen im Vergleich zu dem des Glühfadens sehr hohen Widerstand hat.The invention relates to a resistor for series-connected electrical Incandescent lamps that are connected in parallel to each lamp in a row of lamps. The resistance consists of paper or a similar dielectric, which is on one side with a Layer of bad conductor is coated and pierced from the layer side, so that the poor conductor following the walls of the piercing establish a connection between can produce conductors arranged on both sides of the resistor. You get such a weakly conductive connection, which is one compared to that of the filament has very high resistance.

Es ist bekannt, derartige Widerstände aus zwei durch einen Nichtleiter getrennten Metallstücken herzustellen, welcher der Stromspannung widersteht, solange der Glühfaden heil ist. Wird aber der Faden unterbrochen, so überwindet die infolgedessen auftretende stärkere Spannung die Wirkung des Nichtleiters. It is known that such resistors consist of two pieces of metal separated by a non-conductor to produce, which withstands the voltage as long as the filament is intact. But if the thread is broken, in this way, the higher voltage that occurs as a result overcomes the effect of the dielectric.

Es hat sich herausgestellt, daß derartige Widerstände sehr unsicher arbeiten, namentlich bei Leitungen für schwache Spannung.
Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in stark vergrößertem Maßstabe im Schnitt dargestellt.It has been found that such resistors work very insecurely, especially with lines for weak voltage.
In the drawing, an embodiment of the subject invention is shown in a greatly enlarged scale in section.

Zwischen zwei Metallstücken M — zweckmäßigerweise werden sie aus einem Metall von niederem Schmelzpunkt, z. B. Blei, hergestellt — liegt eine Schicht P aus Isolierstoff, beispielsweise Papier, welche auf einer Seite mit einer Schicht C aus leitendem Stoff bekleidet ist. Es empfiehlt sich, als Leitschicht eine Mischung von feingepulverter Kohle oder Graphit, Wasser oder Gummiarabikum oder einem anderen Klebmittel zu verwenden, damit die Schicht gut an dem Papier haftet. Zum Auftragen verwendet man einen feinen Pinsel oder einen Preßluftzerstäuber.Between two pieces of metal M - they are expediently made of a metal with a low melting point, e.g. B. lead - is a layer P made of insulating material, for example paper, which is covered on one side with a layer C made of conductive material. It is advisable to use a mixture of finely powdered charcoal or graphite, water or gum arabic or another adhesive as the conductive layer so that the layer adheres well to the paper. A fine brush or a compressed air atomizer is used for application.

Wenn das Papier vollständig trocken ist, macht man mit einem spitzen Werkzeug, einer Nadel o. dgl., eine beliebige Anzahl Löcher hindurch, und zwar so, daß das Werkzeug von der Seite her eindringt, welche mit der Leitschicht bezogen ist.When the paper is completely dry, you do it with a sharp tool, a Needle or the like, any number of holes through it, in such a way that the tool penetrates from the side which is related to the conductive layer.

Die beiden Metallstücke M können unter normalen Bedingungen nicht unmittelbar in Berührung treten, werden jedoch durch die" an den Rändern des Loches (oder der Löcher) H abgebogene Leitschicht C miteinander verbunden. Der Widerstand der Leitschicht istThe two metal pieces M cannot come into direct contact under normal conditions, but are connected to one another by the conductive layer C which is bent over at the edges of the hole (or holes) H. The resistance of the conductive layer is

sehr hoch im Vergleich zu dem des Glühfadens einer Lampe für schwache Spannung. Unter normalen Verhältnissen, d. h. solange der Glühfaden heil ist, kann man den Stromdurchgang durch die Hilfsverbindung gleich Null annehmen. Wenn aber der Glühfaden der zugehörigen Lampe unterbrochen wird, so steigt die Spannung zwischen den Metallstücken M derart, daß die Schicht C geschmolzen und der Isolierstoff P teilweise zerstört wird. Die Metallplatten kommen jetzt in unmittelbare Berührung, schmelzen zusammen, und die Hilfsverbindung wird leitend.very high compared to that of the filament of a low voltage lamp. Under normal conditions, ie as long as the filament is intact, the passage of current through the auxiliary connection can be assumed to be zero. If, however, the filament of the associated lamp is interrupted, the voltage between the metal pieces M rises in such a way that the layer C melts and the insulating material P is partially destroyed. The metal plates now come into direct contact, melt together and the auxiliary connection becomes conductive.
