Description
Vorrichtung zum Herstellen von Schallaufzeichnungen Die Erfindung bezieht sich auf eine Vorrichtung für die Zwecke der photographischen Aufzeichnung elektrischer Modulationen, insbesondere für die Zwecke der Tonaufzeichnungen, der Bildtelegraphie u. dgl.Apparatus for making sound recordings The invention relates to an apparatus for the purpose of photographic recording electrical modulations, in particular for the purposes of sound recordings, the Image telegraphy and the like
Es sind bereits zahlreiche Lichtrelais für die Zwecke der photographischen Aufzeichnung von Strommodulationen bekannt. Durch den Erfindungsgegenstand wird jedoch ein neuartiges Lichtrelais geschaffen, bei welchem die durch Piezoelektrizität hervorgerufene Leuchterscheinung an Kristallen nutzbar gemacht wird. Daß Kristalle, durch ein elektrisches Feld erregt, insbesondere in verdünnten Gasen bei Resonanz Leuchterscheinungen auslösen, ist an sich bekannt und wissenschaftlich untersucht worden.There are already numerous light relays for photographic purposes Record of current modulations known. Through the subject matter of the invention However, a new type of light relay was created, in which the piezoelectricity evoked luminous phenomenon on crystals is made usable. That crystals excited by an electric field, especially in dilute gases at resonance Triggering luminous phenomena is known per se and has been scientifically investigated been.
Vorliegende Erfindung macht nun diese Erscheinung in der Weise nutzbar, daß von Schallwellen gesteuerte, mit Hochfrequenz betriebene, leuchtende Entladungen schwingender Kristalle ausgelöst werden, insbesondere in geschlossenen Gefäßen, die zweckmäßigerweise mit die Wirkung erhöhenden Stoffen gefüllt sind.The present invention now makes this phenomenon usable in such a way that that of sound waves controlled, high frequency operated, luminous discharges vibrating crystals are released, especially in closed vessels, which are expediently filled with substances that increase the effect.
Der Erfindungsgedanke ist in der Abbildung in schematischer Weise an Hand eines Ausführungsbeispieles veranschaulicht.The idea of the invention is shown in the figure in a schematic manner illustrated using an exemplary embodiment.
i ist die vom Mikrophon kommende Zuleitung. z ist ein Mikrophontransformator, durch welchen die Mikrophonströme auf die Verstärker- bzw. Modulationseinrichtung übertragen werden. 3 ist ein Modulationsrohr, 4. ein Hochfrequenzrohr, 5 eine Vorspannbatterie, 6 die Selbstinduktionsspule eines Abstimmkreises, 7 ein zwischen Elektroden angeordneter, schwingender Kristall, 8 eine Optik. Das Hochfrequenzrohr q. mit dem Abstimmitte16 in geeigneter Schaltung erzeugt eine hochfrequente Schwingung mit gleichbleibender Amplitude, die den Elektroden des Kristalles 7 zugeführt wird. Durch die Mikrophonströme des Transformators z bzw. durch das Modulationsrohr 3 wird nun die Amplitude der Schwingungen des Hochfrequenzgenerators 4., 6 den Mikrophonströmen entsprechend verändert, so daß auch den Elektroden des Kristalls 7 veränderliche Spannungswerte der Hochfrequenz aufgedrückt werden. Diesen Veränderungen des elektrischen Feldes entsprechend verändert sich auch die Leuchtwirkung des schwingenden Kristalles 7, so daß mit Hilfe der Optik 8 die den Sprechströmen oder den Bildwerten entsprechenden Lichtveränderungen aufgezeichnet werden.i is the lead coming from the microphone. z is a microphone transformer, through which the microphone currents to the amplifier or modulation device be transmitted. 3 is a modulation tube, 4. a high frequency tube, 5 a preload battery, 6 the self-induction coil of a tuning circuit, 7 an arranged between electrodes, oscillating crystal, 8 an optic. The high frequency tube q. with the voting center16 in a suitable circuit generates a high-frequency oscillation with a constant Amplitude which is fed to the electrodes of the crystal 7. Through the microphone streams of the transformer z or through the modulation tube 3 is now the amplitude of the Vibrations of the high frequency generator 4, 6 corresponding to the microphone currents changed so that the electrodes of the crystal 7 also have variable voltage values the high frequency are pressed. These changes in the electric field The luminous effect of the oscillating crystal 7 also changes accordingly, so that, with the aid of the optics 8, those corresponding to the speech streams or the image values Changes in light are recorded.
Die in der Abbildung beschriebene Anordnung stellt ein Ausführungsbeispiel dar, das sinngemäß in mannigfacher Weise abgeändert werden kann. So kann beispielsweise der schwingende Kristall auch in einem geschlissenen Gefäß untergebracht werden, das zweckmäßigerweise mit die Wirkung erhöhenden Gasen gefüllt ist. Auch können zwecks Erregung des elektrischen Feldes am Kristall beliebige Strom- und Schwingungserzeuger in beliebigen Schaltungen benutzt werden.The arrangement described in the figure represents an exemplary embodiment that can be modified in a variety of ways. For example the vibrating crystal can also be housed in a closed vessel, which is expediently filled with the effect increasing gases. Also can for the purpose of exciting the electric field on the crystal, any type of current and vibration generator can be used in any circuit.
Die erfindungsgemäße Vorrichtung bietet infolge ihrer hohen Trägheitslosigkeit, der relativ geringen erforderlichen Betr iebspannung, der hohen Lebensdauer und dem überaus einfachen Aufbau derselben ganz wesentliche Vorteile für die praktische Handhabung und Verwendung.The device according to the invention offers due to its high inertia, the relatively low operating voltage required, the long service life and the extremely simple structure of the same are very substantial advantages for the practical Handling and use.
