Description
Kathodenröhre. Es ist bereits bekannt, die Elektroden von Vakuumröhren mit Elementen der Erdalkaligruppe, wie z. B. Magnesium usw., zu belegen, und zwar soll die Belegung lediglich in der Weise wirken, daB die aus der Kathode freiwerdenden Gase von derselben absorbiert werden.Cathode tube. It is already known the electrodes of vacuum tubes with elements of the alkaline earth group, such as. B. magnesium, etc. to prove, namely the occupancy should only act in such a way that the ones released from the cathode Gases are absorbed by the same.
Auch ist es nicht mehr neu, ohne Heizstrom arbeitende Kathodenröhren herzustellen, bei denen die Kathode homogen aus Magnesium hergestellt ist.It is also no longer new, cathode tubes that work without heating current in which the cathode is made homogeneously from magnesium.
Vorliegende Erfindung bezieht sich darauf, derartige Kathodenröhren, bei welchen die Kathode homogen aus Metallen der Erdalkaligruppe besteht, für die Zwecke der drahtlosen Telegraphie und Telephonie, und zwar zur Kopplung zweier Stromkreise zu verwenden, wobei nur das Kathodenmaterial die Elektronenemission bewirkt. Die Kathodenröhre dient dabei als Ventil, als Verstärker oder als Schwingungserzeuger.The present invention relates to such cathode tubes, in which the cathode consists homogeneously of metals of the alkaline earth group for which Purposes of wireless telegraphy and telephony, namely to couple two electrical circuits to use, with only the cathode material causing the electron emission. the The cathode tube serves as a valve, as an amplifier or as a vibration generator.
