Description

Röhrensender für kurze Wellen Die Erfindung bezieht sich auf eine Schaltung zur Erzeugung kurzer elektrischer Wellen, und .zwar eine Erweiterung der unter dem Namen Holborn-Schaltung bekannten Anordnung. Diese Anordnung ist in Abb. i dargestellt. In ihr bedeuten i und 2 zwei Elektronenröhren, deren Anoden durch den Bügel 3 und deren Gitter durch den Bügel 4 miteinander verbunden sind. Die Selbstinduktionen dieser Bügel bilden in Verbindung mit den Röhrenkapazitäten den Schwingungskreis. Die Mittelpunkte der Bügel sind über Drosseln 5 und 6 mit der Anoden- bzw. Gitterspannungsquelle verbunden.Short wave tube transmitter The invention relates to a Circuit for generating short electrical waves, and indeed an extension of the arrangement known under the name Holborn circuit. This arrangement is shown in Fig. i shown. In it, i and 2 mean two electron tubes with anodes through the bracket 3 and its grid are connected to one another by the bracket 4. The self-inductions this bracket, in conjunction with the tube capacities, form the oscillation circuit. The center points of the bracket are via chokes 5 and 6 with the anode or grid voltage source tied together.

Erfindungsgemäß werden nun in einer ähnlichen Schaltung vier, sechs oder eine noch größere gerade Anzahl von Röhren verwendet. In Abb.2 ist eine Ausführungsform für sechs Röhren dargestellt. Die Röhren sind mit i, 2, i', 2', i", 2" bezeichnet. Die Anoden der Röhren i und 2 sind durch einen Bügel 3 miteinander verbunden, ebenso die Anoden der Röhren i', 2' durch einen Bügel 3' und die Anoden der Röhren i", 2" durch einen Bügel 3#..According to the invention, four, six or an even greater number of tubes is used. In Fig.2 is an embodiment shown for six tubes. The tubes are labeled i, 2, i ', 2', i ", 2". The anodes of the tubes i and 2 are connected to one another by a bracket 3, as well the anodes of the tubes i ', 2' through a bracket 3 'and the anodes of the tubes i ", 2 "through a 3 # ..

Zwischen je zwei Gitter wird ebenfalls ein Bügel gelegt, jedoch - abweichend vom Schaltbild der Abb. i - nicht zwischen -die Gitter zweier Röhren, deren Anoden miteinander verbunden sind, sondern zwischen die Gitter zweier Röhren, die zu verschiede4nen Paaren gehören. So sind die Gitter der Röhren 2 und i' durch den Bügel 4, die Gitter der Röhren 2' und i" durch den Bügel 4', die Gitter der Röhren. 2" und i durch den Bügel 4" verbunden.A bracket is also placed between every two grids, but - deviating from the circuit diagram in Fig. i - not between - the grids of two tubes, whose anodes are connected to each other, but between the grids of two tubes, belonging to different pairs. So the grids of tubes 2 and i 'are through the bracket 4, the grilles of the tubes 2 'and i "through the bracket 4', the grilles of the Tubes. 2 "and i are connected by bracket 4".

Die Mittelpunkte der Bügel 3, 3', 3" sind über Drosseln 5, 5', 5" an die Anodenspannungsquelle, die Mittelpunkte der Gitter 4, 4', 4" an die Gitterspannungsquelle angeschloflen.The centers of the brackets 3, 3 ', 3 "are above throttles 5, 5', 5" to the anode voltage source, the center points of the grids 4, 4 ', 4 "to the grid voltage source connected.

Sämtliche Kathoden sind, nötigenfalls über Drosseln, die in der Abbildung nicht gezeichnet sind, miteinander verbunden.All cathodes are, if necessary via chokes, the ones in the figure are not drawn, connected to each other.

Der Vorteil dieser Schaltung liegt einerseits in der Addition der Leistung mehrerer einzelner Röhren, andererseits darin, daß sich sowohl die Selbstinduktionen der Bügel als auch die Kapazitäten der Röhren hintereinanderschalten, so daß der entstehende Schwingungskreis zwar dieselbe Wellenlänge, aber ein wesentlich günstigeres Verhältnis von Selbstinduktion zu Kapazität besitzt als ein Sender mit nur zwei Röhren.The advantage of this circuit is on the one hand in the addition of the Power of several individual tubes, on the other hand, in the fact that both the self-induction the bracket and the capacities of the tubes are connected in series, so that the The resulting oscillation circuit has the same wavelength, but a much cheaper one Ratio of self-induction to capacity has as a transmitter with only two Tubes.
