Gasentladungsstrecke zur Steuerung elektrischer Ströme unter EinwirkungGas discharge path for controlling electrical currents under the influence
von Schallkräften.of sound forces.
Patentiert im Deutschen Reiche vom 23. Juni 1920 ab. Längste Dauer: 2. August 1934.Patented in the German Empire on June 23, 1920. Longest duration: August 2, 1934.
In dem Hauptpatent ist ein Verfahren angegeben, Schalldruckschwankungen zur Steuerung einer unselbständigen Gasentladung bei Atmosphärendruck zu benutzen. Der Widerstand derartiger Gasentladungsstrecken ist sehrThe main patent specifies a method for controlling sound pressure fluctuations to use a dependent gas discharge at atmospheric pressure. The resistance such gas discharge paths is very
hoch. Er bewegt sich ungefähr zwischen 2 bis 8.106 Ω und kommtfdamit in die Größenordnung des Widerstandes, den kleine Kapazitäten (etwa 10 bis 50 cm) bei mittleren Tonfrequenzen (etwa 1000 Schwingungen pro Sekunde) be-high. It moves approximately between 2 to 8.10 6 Ω and thus comes in the order of magnitude of the resistance that small capacitances (about 10 to 50 cm) at medium sound frequencies (about 1000 oscillations per second) have.
sitzen. Würden derartige Kapazitäten parallel zum Entladungsweg liegen, so sind sie für die an der Entladungsstrecke infolge der Schallschwingungen auftretenden Spannungsschwankungen Nebenschlüsse und schwächen diese Spannungsschwankungen, die das Gitter einer Verstärkerröhre steuern sollen, erheblich, und zwar entsprechend dem Verhältnis der Widerstände. Die gleichen Gesichtspunkte gelten ίο auch für Ohmsche Nebenwege.sit. If such capacities were parallel to the discharge path, they are for the Voltage fluctuations occurring at the discharge path as a result of the sound vibrations Shunts and weaken these voltage fluctuations, which are intended to control the grating of an amplifier tube, considerably, and according to the ratio of the resistances. The same considerations apply ίο also for Ohmic byways.
Die Erfindung berücksichtigt diese Erkenntnis und bezweckt, die konstruktive Ausführung des nach dem Verfahren des Hauptpatentes arbeitenden Apparates vor vorstehend erörterten Nachteilen zu schützen, indem der Apparat derart gedrängt zusammengebaut ist, daß Isolationsverluste und kapazitive Nebenschlüsse auf ein Minimum vermindert bzw. ganz beseitigt sind. Hierzu werden das Gehäuse und die stromführenden Teile durch ein geeignetes. Material (insbesondere Glimmer, Glas, Porzellan) isoliert.The invention takes this knowledge into account and aims at the constructive execution of the apparatus operating according to the method of the main patent discussed above To protect disadvantages by the apparatus is assembled so crowded that insulation losses and capacitive shunts are reduced to a minimum or completely eliminated. For this purpose, the housing and the current-carrying parts are replaced by a suitable. Material (especially mica, glass, porcelain) insulated.
In den Abb. 1 und 2 sind Ausführungsbeispiele für ein handliches Modell schematisch dargestellt. Abb. 1 zeigt das Modell im Längsschnitt, Abb. 2 zeigt einen Teil bei gleichem Schnitt, nur um 90 ° gedreht. Der Sockel s, der im schallauffangenden Trichter t sitzt, trägt die Anodendüse d, die sich in einer flachen .30 Klemme« befindet, ebenso (Abb. 2) die Kathode A, die federnd an den Anschluß- und Halteklemmen A1, A2 gelagert ist, die untereinander und gegen den Sockel s vermittels der Glimmerzwischenlage i isoliert sind. Gegen seitliche Verschiebungen sind die drei Halteklemmen durch Paßstifte φ, ft aus Glas oder Porzellan gesichert. Die Klemmen werden durch den ebenfalls isoliert angebrachten Druckring r, dessen Befestigung nicht gezeichnet ist, an den Sockel s gepreßt. Über dem Apparat befindet sich, die mit einer Beobachtungsöffnung f versehene Schutzhülse h. In Figs. 1 and 2, exemplary embodiments for a handy model are shown schematically. Fig. 1 shows the model in longitudinal section, Fig. 2 shows a part with the same section, only rotated by 90 °. The base s, which sits in the sound-collecting funnel t , carries the anode nozzle d, which is located in a flat .30 clamp «, as well as (Fig. 2) the cathode A, which is resiliently attached to the connecting and holding clamps A 1 , A 2 is stored, which are isolated from each other and from the base s by means of the mica intermediate layer i. The three retaining clips are secured against lateral displacement by dowel pins φ, ft made of glass or porcelain. The clamps are pressed against the base s by the pressure ring r, which is also insulated and the fastening of which is not shown. The protective sleeve h , which is provided with an observation opening f, is located above the apparatus.
Die Kathode A wird durch den über die Klemme A1, A2 zugeführten Heizstrom zum Glühen gebracht. Zwischen ihr und der Anode d liegt die Entladungsspannung. Bei entsprechender Temperatur geht zwischen d und A eine kontinuierliche Entladung über, die durch die Schallwellen, die über t in Pfeilrichtimg eindringen, gesteuert wird. 'The cathode A is made to glow by the heating current supplied via the terminals A 1 , A 2. The discharge voltage lies between it and the anode d. At a suitable temperature, a continuous discharge passes between d and A, which is controlled by the sound waves that penetrate via t in the direction of the arrow. '
Bei der aus der Zeichnung ersichtlichen Anordnung der Isolationsmaterialien und- der stromführenden Teile sind Ohmsche Nebenschlüsse durch Schaffung genügend langer Kriechwege vermieden und kapazitive Nebenwege durch Verminderung der Kapazitäten (kleinste Auflageflächen, Isolierung der Kathode und der Anode vom Sockel) auf ein Minimum reduziert.In the arrangement of the insulation materials and the arrangement shown in the drawing Live parts are ohmic shunts by creating sufficiently long creepage distances and avoid capacitive bypasses by reducing the capacities (smallest contact surfaces, insulation of the cathode and the anode from the base) is reduced to a minimum.
Um nicht durch längere Verbindungsleitungen schädliche Kapazitäten zu schaffen, hat es sich ferner als sehr vorteilhaft erwiesen, die schallempfindliche Entladungsstrecke und die Verstärkereinrichtung baulich zu vereinigen. In Abb. 3 ist dies schematisch veranschaulicht. In dieser Abbildung ist a, k die Entladungsstrecke nach dem Hauptpatent, R eine Verstärkerröhre, g der die Anordnung umschließende Kasten.In order not to create harmful capacities through longer connecting lines, it has also proven to be very advantageous to structurally combine the sound-sensitive discharge path and the amplifier device. This is illustrated schematically in Fig. 3. In this figure, a, k is the discharge path according to the main patent, R is an amplifier tube, and g is the box enclosing the arrangement.
