Description

Verfahren zur Steuerung elektrischer Ströme durch Schallkräfte. Gegenstand.- des Hauptpatentes 350500 ist ein Verfahren zur Steuerung elektrischer Ströme durch Schaltkräfte, nach welchem eine =selbständige Entladung .in der freien Atmosphäre als Schallaufnahmemittel benutzt wird.Method for controlling electrical currents by means of sound forces. The subject of the main patent 350500 is a method for controlling electrical currents by switching forces, according to which an = independent discharge .in the free atmosphere is used as a sound absorbing device.

Gemäß vorliegender Erfindung wird -der Wirkungsgrad dieses Verfahrens unter sonst .nUichen Verhältnissen -um ein Vielfaches gesteigert, wenn deriartig hohe Anodenspannungen angewendet werden, daß in der Entladungsstrecke der an sieh bekannte Effekt der Stoßionisation eintritt. Beispielsweise tritt dies ein, wenn de an der Entladungsstrecke liegende Spannung etwa q.oo Volt übersteigt. Der Effekt kann leicht an der starken Aufwärtskrümmungeiner Kurve festgestellt werden, die bei konstanter Kathodenheizung :die Abhängigkeit des An odenstronifes von der Anodenspannung veranschaulicht.According to the present invention, the efficiency of this method under otherwise normal conditions - increased by a multiple, if this is the case high anode voltages are used that in the discharge path of the see known effect of impact ionization occurs. For example, this occurs when de voltage on the discharge path exceeds about q.oo volts. The effect can easily be identified by the sharp upward curvature of a curve that with constant cathode heating: the dependence of the anode tronifes on the anode voltage illustrated.

Die Herstellung @derartig hoher Spannungen (bis 8oo Volt) ist wegen der Konstanz für den Erfindiungszweck nur mittels. Elemente möglich ,und bietet praktisch erhebliche Schwi@eriäkeiten. Diese werden erfindungsgemäß .dadurch beseitigt, d:aß kleine,den Voltasäulen ähnliche Batterien. mit tellerförmigen Elektroden Anzvendung finden. Hierdurch verringern sich ferner die Eeschaffungskosten wesentlich, außerdem wind :ein viel 'kleinerer Raum #be-.nötngt, -was bei der aStoß.ionisatvon in einer ionisierten Gasstrecke nach dem Hauptpatent von wesentlicher Bedeutung ist.The production of such high voltages (up to 8oo volts) is due to the constancy for the purpose of the invention only by means of. Elements possible, and offers practically considerable difficulties. According to the invention, these are eliminated by d: ate small batteries similar to the voltaic pillars. with plate-shaped electrodes Find. This also reduces the acquisition costs significantly, as well wind: a much smaller space # is-.necessary, -what with the shock.ionisatof in one ionized gas line according to the main patent is essential.
