ausstrallungsvermögen und damit ihre Belastbarkeit erhöht. Der Draht, aus dem das Drahtgeflecht für die Anode hergestellt ist, besitzt also einen so kleinen Durchmesser, dass er in blankem Zustande die auf die Anode entfallende Belastung nicht vertragen würde, und hält diese erst durch die Schwärzung seiner Oberfläche aus. Beispielsweise kann man einer durchbrochenen Elektrode einer Empfängerendröhre üblicher Grosse, die aus Drahtgaze von 60 Maschen je Zoll mit einer Drahtstärke von 0. 15 mm besteht, durch Schwärzung eine Dauerbelastungsfähigkeit von 6 Watt verleihen.
Durch die Kombination der beiden oben angeführten Massnahmen wird ein wichtiges Problem der Röhren mit fünf und mehr durchbrochenen Elektroden gelöst, indem sowohl für die äusserste als auch für die inneren Elektroden, z. B. die oft als eigentliche Anode wirkende vorletzte Elektrode, günstige thermische Verhältnisse geschaffen werden.

capacity and thus their resilience increased. The wire, from which the wire mesh for the anode is made, has such a small diameter that it would not be able to withstand the load on the anode in a bare state, and can only withstand this through the blackening of its surface. For example, an openwork electrode of a receiver end tube of the usual size, which consists of wire gauze of 60 meshes per inch and a wire thickness of 0.15 mm, can be given a continuous load capacity of 6 watts by blackening it.
By combining the two measures listed above, an important problem of the tubes with five or more perforated electrodes is solved by both the outer and the inner electrodes, z. B. the penultimate electrode, which often acts as the actual anode, creates favorable thermal conditions.
