Description
Einrichtung zur Frequenzsteigerung Zusatz zum Patent 426 874 Das Patent 426 974 betrifft eine Einrichtung zur Frequenztransformation, bei der am rrequenztransförmator eine Kapazität angeschaltet ist. Die Erfindung betrifft eine weitere Verbesserung dieser Anordnung.Device to increase frequency Addition to patent 426 874 The patent 426 974 relates to a device for frequency transformation, in the case of the at the frequency transformer a capacitance is switched on. The invention relates to a further improvement this arrangement.
In Abb. i ist i irgendeine Wechselstromquelle, 2 und 3 Abstimmittel dafür und 4 eine Drosselspule, die schematisch einfacher gezeichnet ist als im Hauptpatent. 5, 6, 7, 7a bilden mit der Sekundärwicklung der Drosselspule 4 den selektiven höherfrequenten Kreis einer Vielfachen der Grundfrequenz. 8 ist ein Parallelkondensator nach Patent 426 874, der ebenfalls in der Hauptsache dieselbe Frequenz führt wie der Kreis 4, 5, 6, 7, 7a. In Abb. 2 liegt der mit der Antenne gekoppelte Kreis, wie meist üblich, an der Primärwicklung der. Drosselspule 4 (prinzipiell ist nur diese eine Wicklung nötig). An der Sekundärwicklung kann noch ein weiterer selektiver Kreis von Nutzfrequenz liegen, der aus 4, 14, 15 gebildet wird.In Fig. I i is any alternating current source, 2 and 3 tuning means for it and 4 a choke coil, which is schematically drawn more simply than in the main patent. 5, 6, 7, 7a, together with the secondary winding of the choke coil 4, form the selective higher-frequency circuit of a multiple of the fundamental frequency. 8 is a parallel capacitor according to patent 426 874, which also mainly has the same frequency as the circuit 4, 5, 6, 7, 7a. In Fig. 2, the circle coupled to the antenna is, as is usually the case, on the primary winding of the. Choke coil 4 (in principle only this one winding is necessary). Another selective circuit with a useful frequency, which is formed from 4, 14, 15, can be connected to the secondary winding.
Neben- und Oberwellen werden durch Einschaltung sehr großer Selbstinduktionen (Patent 44426i) in den selektiven Kreis fast restlos unterdrückt. Das Neue der vorliegenden Erfindung besteht nun in der Benutzung einer relativ kleinen Kapazität 13, die parallel zu einem Teil oder der ganzen Selbstinduktion im selektiven Kreise liegt -zwecks Vernichtung auch des letzten Restes an umerwünschten Schwingungen. Dabei ergibt sich die interessante und sehr willkommene Tatsache, daß die Kombination 13, 6, 7 nicht etwa als Sperrkreis für die Nutzfrequenz abgestimmt ist, sondern kleiner, auf etwa 3/4 bis 2/3, davon.Side waves and harmonics are created by switching in very large self-inductions (Patent 44426i) is almost completely suppressed in the selective circle. The novelty of the present Invention now consists in the use of a relatively small capacitance 13, the parallel part or all of the self-induction is in the selective circle-purpose Destruction of the last remnant of undesired vibrations. This results in the interesting and very welcome fact that the combination 13, 6, 7 is not tuned as a blocking circuit for the useful frequency, but smaller, to about 3/4 to 2/3 of that.
Ein Beispiel: Die Nutzwelle sei i 12o m, die Nebenwelle 1200 m. Diese verschwindet, wenn die Kombination 13, 6, 7 auf etwa 80o m abgestimmt wird. -Die zu 13 parallel liegende Kombination der Kapazitäten 8 und 5 mit den Selbstinduktionen 4 und 711 ergibt den Effekt.An example: Let the useful wave be i 12o m, the secondary wave 1200 m disappears when the combination 13, 6, 7 is tuned to about 80o m. -The to 13 parallel combinations of capacities 8 and 5 with self-induction 4 and 711 gives the effect.
Das kleine Variometer 7a ist zweckmäßig, um den selektiven Kreis 4, 5, 6, 7, 7a nachzustimmen, wenn 13, 6, 7 auf die Störwelle eingestellt wird. Die Variometer können natürlich wegfallen oder durch Spulen ersetzt werden, wenn Drehkondensatoren verwendet werden.The small variometer 7a is useful to readjust the selective circle 4, 5, 6, 7, 7a when 13, 6, 7 is set to the disturbance wave. The variometers can of course be omitted or replaced by coils if variable capacitors are used.
