Description
Einrichtung zur Ausführung des Verfahrens zur Steuerung elektrischer Ströme durch Schallkräfte. Bei dem den Gegenstand des Hauptpatentes 35o5oo bildenden Verfahren zur Steuerung elektrischer Ströme durch Schallkräfte kann die erforderliche Gasionisation durch eine geheizte Kathode hergestellt werden. Hierbei ist die Anode als Düse ausgebildet, durch die die Schalldruckschwankungen in den Entladungsweg gelangen und die Charakteristik des Entladungsstromes in Abhängigkeit von den Schallkräften beeinflussen.Device for carrying out the method for controlling electrical Currents through sound forces. In the case of the subject of the main patent 35o5oo Method for controlling electrical currents by sound forces can be the required Gas ionization can be produced by a heated cathode. Here is the anode designed as a nozzle through which the sound pressure fluctuations in the discharge path and the characteristics of the discharge current as a function of the sound forces influence.
Erfindungsgemäß wird die Gleichmäßigkeit zwischen den Schalldruckschwankungen und den Stromschwankungen dadurch gefördert, daß zwischen dem Schallauffangorgan und der Anodendüse ein Schalleiterstück eingefügt wird, das zweckmäßig kurz und annähernd zylindrisch ist. Die hierdurch erzielte Proportionalität zwischen Schalldruck- und Stromschwankungen beruht offenbar auf der Umwandlung der flächenhaften (kugelwellenförmigen) Schallwellen in Strömungserscheinungen, die für den Steuervorgang in der Entladungsstrecke von besonderer Bedeutung sind, da durch das hierdurch verursachte Zuströmen nichtionisierter Luft der Widerstand der Gasstrecke die notwendige, für die Mikrophonwirkung erforderliche Änderung erfährt.According to the invention, the uniformity between the sound pressure fluctuations becomes and the current fluctuations promoted by the fact that between the sound collecting element and a sound conductor piece is inserted into the anode nozzle, which is expediently short and is approximately cylindrical. The resulting proportionality between sound pressure and current fluctuations is apparently based on the transformation of the two-dimensional (spherical wave-shaped) Sound waves in flow phenomena that are responsible for the control process in the discharge path are of particular importance because the influx caused by this is non-ionized Air the resistance of the gas train the necessary for the microphone to work Changes.
In der Abbildung ist beispielsweise eine Ausführungsform der Erfindung dargestellt. An den schallauffangenden Trichter t ist ein zweckmäßig röhrenförmiges, gegebenenfalls als Anodendüse ausgebildetes Zwischenstück d angeschlossen, dessem Ende die Kathode h gegenübersteht. Dieser Schalleiter d ist als Düse ausgebildet, die nach der Entladungsstrecke zu konisch verläuft. Für die Erhöhung der Stromschwankungen durch die Schallkräfte kann es ferner von Vorteil sein, diese Düse als Spaltdüse flach auszuführen, wobei sie mit dem Schalleiter aus einem Stück bestehen oder getrennt von diesem vorgesehen sein kann.For example, the figure shows an embodiment of the invention shown. A suitably tubular, optionally designed as an anode nozzle adapter d connected, desem End facing the cathode h. This sound conductor d is designed as a nozzle, which is too conical after the discharge path. For increasing the power fluctuations Due to the sound forces, it can also be advantageous to use this nozzle as a slot nozzle flat, whereby they consist of one piece with the sound conductor or separate can be provided by this.
