Description
Verfahren zum periodischen, schnell vor sich gehenden Ândern (Wobbeln) von Senderwellen Es ist bekannt, Bine periodisch verânderliche Kapazitât dadurch herzustellen, daB man entsprechend ausgebildete Kondensatorplatten (z. B. in Form von konzentrisch angeordneten Zahnrâdern) gegeneinander rotieren lâ0t.Procedure for periodic, rapid changes (wobbling) of transmitter waves It is known to have a periodically changing capacity as a result to produce capacitor plates designed accordingly (e.g. in the form of of concentrically arranged gears) can rotate against each other.
In vielen Fâllen, insbesondere zur geringen Wellenânderung beim drahtlosen Telegraphieren und Telephonieren mit kurzen Wellen, kann es nun erwünscht sein, daB die periodische Verânderung der Kapazitât mdglichst konstant oder mbglichst sinusfdrmig oder beides zugleich sein soll, w as aber bei der rotierenden Bewegung der Kondensatorplatten mit Schwierigkeiten verbunden ist.In many cases, especially for the small wave change in wireless Telegraphing and telephoning with short waves, it may now be desirable that the periodic change in capacity is as constant or as possible as possible should be sinusoidal or both at the same time, but what about the rotating movement the capacitor plates is associated with difficulties.
Nach der Erfindung werden daher die in Betracht kommenden Kondensatorplatten durch ein mit konstanter Eigenschwingung schwingendes System in gegenseitige Schwingungen versetzt, wod-urch ihr gegenseitiger kapazitiver Widerstand mit konstanter Periodenzahl und gant odes nahezu sinusffirmig sich v erândert.According to the invention, therefore, the capacitor plates in question by a system oscillating with constant natural oscillation into mutual oscillations offset, what-ure their mutual capacitive resistance with constant number of periods and gant odes changes almost sinusoidally.
Am einfachsten ist die Ausführung der Erfindung, wenn man eine Kondensatorplatte festmacht und die andere mit einem Vibrator verbindet, der auf irgendeine bekannte Art (z. B. durch einen Rôhren.generator) in konstante Schwingungen versetzt wird.The easiest way to carry out the invention is to use a capacitor plate and connects the other to a vibrator that works on some known Art (e.g. by a tube generator) is set in constant oscillation.
Da es auf die gegenseitige Bewegung der Kondensatorplatten gegeneinander ankommt, so kann man selbstverstândlich beide Platten beweglich machen, indem man sie beispielsweise mit den beiden Enden einer Stimmgabel verbindet, die in bekannter Weise in dauernde Eigenschwingungen gebracht wird.Because it is due to the mutual movement of the capacitor plates against each other arrives, you can of course make both plates movable by adding it connects, for example, with the two ends of a tuning fork, which in well-known Way is brought into permanent natural vibrations.
Durch Einstellung der Schwingungszahl des Systemes kann die Periodenzahl der Kapazitâtsânderung beliebig eingestellt werden.By setting the number of oscillations of the system, the number of periods the capacity change can be set as required.
