Selbsttätige Z ü n d v o r r i c h t u n g f ü r B o g e n l a m p e n.
Merling beschreibt in seinem Buche #Elektrisch Beleuchtung", Braunschweig 1884, # 101, eine Ausführung von jablochkoffkerzen, bei welcher zwischen den beiden nebeneinanderstehendell Kohlen eine aus Gips und Metallspränen bestehende Isoliermasse angeordnet wird, deren den Kohlenspitzen zunächst befindliches Ende durch die Einwirkung
EMI1.1
fähigkeit erhält. Wenn die Lampen ausgeschaltet werden oder von selbst erlöschen, so verursacht dieser schwach leitende Teil des Isolierstabes, wie tatsächlich festgestellt ist, vermutlich, indem er sehr heiss wird und die umgrenzende Luft ionisiert, die selbsttätige erneute Entstehung des Lichtbogens.
Dauerversuche, die sich auf einen aus Asbest und Graphit bestehenden Isolierstab bezogen, haben ergeben, dass sich der leitend
EMI1.2
bogen wegen Fehlens des Kontaktes zwischen c und den Kohlen nicht mehr. Um nun diesen Mangel der Spaltbildung nur in der Nähe von c zu beseitigen, verfährt man der

gewissen Tiefe durch Einwirkung eines Lichtbogens leitfähig macht, ehe der Stal) mit den Kohlen vereinigt wird. Wenn dann die Spalten a und b auch wirklich auftreten, so ist der Kontakt zwischen c und den Kohlen e und f nicht unterbrochen, die Lampe entzündet sich also bei Einschaltung wieder von selbst.

Automatic ignition for arch lam p e s.
Merling describes in his book "Electrical Lighting", Braunschweig 1884, # 101, a version of jablochkoff candles, in which between the two coals standing next to each other an insulating compound consisting of plaster of paris and metal splinters is arranged, the end of which is initially located at the coal tips due to the action
EMI1.1
ability gets. When the lamps are switched off or go out by themselves, this weakly conductive part of the insulating rod, as has actually been established, presumably causes the arc to re-emerge automatically by becoming very hot and ionizing the surrounding air.
Long-term tests based on an insulating rod made of asbestos and graphite have shown that the conductive
EMI1.2
did not bend due to the lack of contact between c and the coals. In order to eliminate this lack of gap formation only in the vicinity of c, the procedure is followed
EMI1.3
makes it conductive to a certain depth by the action of an electric arc, before the stal) is united with the coals. If the gaps a and b really appear, the contact between c and the coals e and f is not interrupted, so the lamp ignites again by itself when it is switched on.
