Claims (1)

2. einrichtung nach anspruch 1. dadurch gekennzeichnet, dass in der den Hochfrequenz- apparat enthaltenden Leitung eine kleine Gasentladungslampe, zweckmässig Kathodenglimmlichtlampe. eingebaut ist. die eine niedrigere Zündspannung als die verwendete Betriebsspannung. aber eine die Brennspanmmg der Leuchtröhre übersteigende Abreissspannung besitzt. 2. Device according to claim 1. characterized in that in the line containing the high-frequency apparatus a small gas discharge lamp, expediently a cathode glow lamp. is built in. which have a lower ignition voltage than the operating voltage used. but has a tear-off voltage that exceeds the burning voltage of the fluorescent tube. 3. Einrichtung nach den Ansprüchen l und 2 mit einem die Betriebsstromleitungen überbrückenden, zur Heizung der Glühelektroden dienenden Transformator, dadurch gekennzeichnet, dass der Heiztransformator ebenfalls hinter dem den nötigen spannungsabfall der Entladungsstrecke liefernden Widerstand liegt. EMI4.2 mit der Primärspule des Heiztransformators eine kleine Gasentladungslampe (.'27) oder pill Widerstand mit stark negativem Temperaturkoeffizienten. z. B. ein Siliziumstab, gesehaltet ist. 3. Device according to claims l and 2 with a transformer bridging the operating current lines and serving to heat the glow electrodes, characterized in that the heating transformer is also located behind the resistor which supplies the necessary voltage drop in the discharge path. EMI4.2 with the primary coil of the heating transformer a small gas discharge lamp (.'27) or pill resistor with a strongly negative temperature coefficient. z. B. a silicon rod is held.
