Elektrode für Bogenlampe.
Die Brenndauer der Elektroden nach Stamm-Patent Nr 33992 lässt sich vergrössern, wenn man der Masse der Metalloxyde und Metalle eine gewisse Menge eines Silikates zusetzt. Es ist zwar bei Kohlenelektroden, welche Dochte besitzen, bekannt, dem Kohlenstoff der Dochtmasse Natriumsilikat (Wasserglas) beizufügen zu dem Zwecke, die Leitfähigkeit der Gassäule des Licht- hngens zu erhöhen : eine Verlängerung der Brenndauer tritt jedoch bei Dochtkohlen durch den
EMI1.1
Metalloxyd und Metall eine flüssige Schmelze, welche weniger schnell verdampft, wenn der Schmelze ein, Silikat beigemischt ist; die Beimischung eines Silikates zu dieser Schmelze hat den weiteren Vorteil, dass die Schmelze schwerer flüssig wird und dass die Rauchbildul1g der Elektroden verringert wird.
Naturemäss darf der Zusatz von Silikat zu der Masse der Elektrode nicht zu gross

Electrode for arc lamp.
The burning time of the electrodes according to Stamm patent no 33992 can be increased if a certain amount of a silicate is added to the mass of metal oxides and metals. In the case of carbon electrodes which have wicks, it is known to add sodium silicate (water glass) to the carbon of the wick material for the purpose of increasing the conductivity of the gas column of the light hanging: however, the burning time of wick carbon is extended by the
EMI1.1
Metal oxide and metal a liquid melt which evaporates less quickly if a silicate is added to the melt; The addition of a silicate to this melt has the further advantage that the melt becomes more difficult to liquid and that the smoke formation of the electrodes is reduced.
Naturally, the addition of silicate to the mass of the electrode must not be too great
