Description

. Verfahren zur Konstanthaltung der Tourenzahl. Im Patent 327112 ist ein Verfahren zum Konstanthalten der Tourenzahl einer Antriebsmaschine, insbesondere zum Konstanthalten der Frequenz eines Hochfrequenznetzes zum Zwecke der drahtlosen Telegraphie und Telephonie beschrieben, welches sich dadurch kennnzeichnet, daß der die Geschwindigkeit der Antriebsmaschine regelnde Apparat oder ein Teil desselben proportional einer Differenz von zwei Frequenzen, zwei Spannungen oder zwei Strömen betätigt wird, von denen die eine proportional der Frequenz des Netzes, während die andere eine konstante oder nahezu konstante Größe ist. . Procedure for keeping the number of tours constant. Patent 327112 describes a method for keeping the number of revolutions of a prime mover constant, in particular for keeping the frequency of a high-frequency network constant for the purpose of wireless telegraphy and telephony, which is characterized in that the apparatus regulating the speed of the prime mover or a part of it is proportional to a difference of two frequencies, two voltages or two currents is operated, one of which is proportional to the frequency of the network, while the other is a constant or almost constant quantity.

Bei der praktischen Ausführung des Verfahrens zeigt sich der Nachteil, daß durch die Differenzwirkung nur verhältnismäßig schwache Regulierwirkungen ausgelöst werden können. Um diesen Übelstand zu beheben, wird gemäß der vorliegenden Erfindung die Differenz zwischen den Frequenzen, Spannungen oder Strömen dadurch in ihrer Wirkung gehoben, daß zwischen dem Reguliersystem und dem Kreise, in welchem die Differenz erzeugt wird, eine Verstärkungseinrichtung, z. B. ein Kathodenrelais vorgesehen ist. , Die Erfindung ist an Hand der beiliegenden Zeichnung in einer beispielsweisen Ausführung näher erläutert.In the practical implementation of the method, the disadvantage is that only relatively weak regulating effects can be triggered by the differential effect. To remedy this drawback, according to the present invention, the difference between the frequencies, voltages or currents is raised in their effect that between the regulating system and the circuit in which the difference is generated, an amplifying device, e.g. B. a cathode relay is provided. The invention is explained in more detail with reference to the accompanying drawings, in an exemplary embodiment.

N ist das Netz, in dem beispielsweise die Frequenz n'. konstant gehalten werden soll. Dieses Netz arbeitet vermittels des lose gekoppelten Transformators T auf einen Schwingungskreis L, dessen Eigenperiodenzahl eine andere (n2) als die des Netzes N (n1) ist. Der Schwingungskreis wird beispielsweise durch eine Kathodenröhre G mit dieser Frequenz erregt. In dem Schwingungskreise entstehen dann Schwingungen von n' bis n2 , gleich "3 Perioden. Während man gemäß dem Hauptpatent mit dieser Periodenzahl den zur Regelwirkung dienenden Motor M speist, ist gemäß der Erfindung in den Schwingungskreis ein besonderer Transformator t eingebaut, durch welchen die Differenzschwingung des Kreises L auf eine beliebige Verstärkervorrichtung, z. B. einen Kathodenröhrenverstärker V gebracht wird, dessen verstärkte Energie vom Anodenkreis auf - den zu regelnden Motor M übertragen wird. N is the network in which, for example, the frequency n '. should be kept constant. This network works by means of the loosely coupled transformer T on a resonant circuit L, the natural number of which is different (n2) than that of the network N (n1). The oscillation circuit is excited, for example, by a cathode tube G with this frequency. Oscillations from n 'to n2 , equal to "3 periods, then arise in the oscillation circuit. While according to the main patent this number of periods is used to feed the motor M serving for the control effect, according to the invention, a special transformer t is built into the oscillation circuit through which the differential oscillation . L of the circle to an arbitrary amplifier device, for example, is brought a cathode tube amplifier V, the amplified energy from the anode circuit to: - the transmitted to be controlled motor M.

Selbstverständlich kann die Anwendung der Verstärkung V auch in allen den in dem Hauptpatent beschriebenen Abänderungsschaltungen des Regulierverfahrens angewendet werden.It goes without saying that the amplification V can also be used in all the modification circuits of the regulation method described in the main patent be applied.
