  Telephonographischer Aufnahmeapparat. 



   Die vorliegende   Etiludung   betrifft die elektromagnetische Einrichtung von tele-   phonographischen   Aufnahmeapparaten. Die Sprechwellen werden in elektrische Wechselströme verwandelt und die letzteren, um eine gute Wirkung zu erzielen, durch ein Telephonrelais   verstärkt.   Die Ausführung ist in der Zeichnung unter der besonderen Annahme dargestellt, dass eine Liebenröhre als   Telephonrelais   verwendet wird. Der Mikrophonstromkreis M, durch welchen die Variationen in der   Liebenschen   Entladungsröhre hervorgebracht werden, ist in Fig. 1 sichtbar. Die Sekundärwicklung S ist mit der 
 EMI1.1 
 nach bekannter Art verbunden. 



   Der verstärkte Strom wird der sekundären Wicklung eines Transformators entnommen, dessen primäre Wicklung von einem durch das Liebenrelais gelieferten   pulsi-   renden Gleichstrom durchflossen wird. Nach vorliegender Konstruktion wird dieser Transforwator als Elektromagnet 3 ausgebildet und es sollen seine   Kraftlinienpulsationen   zur Beeinflussung des Gravierstiftes mitbenutzt werden, während gleichzeitig ein zweiter Elektromagnet 2, der in bekannter Weise durch eine von der Batterie B gespeiste Spule 
 EMI1.2 
 formators erregt wird. Hiedurch wird eine Verbesserung der Einwirkung erzielt. Der Gravierapparat besteht demnach im Wesen aus zwei Elektromagneten, welche auf eine 
 EMI1.3 
 haltenen Impulse durch eine Hebeleinrichtnng auf den Gravierstift 4.

   Zur richtigen E ; ;, stellung der Platte wird eine Mikrometerschraube 5, welche die Entfernung der Platte von den Polen der Elektromagnete reguliert, angeordnet. Fig. 2 veranschaulicht eine Anordnung mit einem   Hufeisenmagneten, dessen beide Schenke !   der   Gleichstrom P aus der   Batterie B umkreist, während um die beiden Pole der   verstärkte Sekundärstrom des   Transformators 3 sinnrichtig fliesst.

  Telephonographic recording apparatus.



   The present study concerns the electromagnetic installation of telephonographic recorders. The speech waves are converted into electrical alternating currents and the latter, in order to achieve a good effect, are amplified by a telephone relay. The design is shown in the drawing with the special assumption that a love tube is used as a telephone relay. The microphone circuit M, by means of which the variations in the Liebensian discharge tube are produced, can be seen in FIG. The secondary winding S is with the
 EMI1.1
 connected in a known manner.



   The amplified current is taken from the secondary winding of a transformer, the primary winding of which is traversed by a pulsating direct current supplied by the Lieben relay. According to the present construction, this transformer is designed as an electromagnet 3 and its line of force pulsations should also be used to influence the engraving pen, while at the same time a second electromagnet 2, which is fed in a known manner by a coil fed by the battery B.
 EMI1.2
 formator is excited. This improves the effect. The engraving apparatus essentially consists of two electromagnets, which act on one
 EMI1.3
 holding impulses by a lever device on the engraving pen 4.

   To the correct E; ; Position of the plate is a micrometer screw 5, which regulates the distance of the plate from the poles of the electromagnets, placed. Fig. 2 illustrates an arrangement with a horseshoe magnet, the two taverns! the direct current P from the battery B circles around the two poles of the amplified secondary current of the transformer 3 flows correctly.
