Description

Einrückvorrichtung für -Empfänger für Bildtelegraphie mit rotierender Bildtrommel Die Erfindung betrifft eine Einrückv orrichtung für Bildtelegraphieempfänger mit rotierender Bildtrommel, durch welche der axial: Vorschub der Trommel bei laufender Trommel bequem ein- und ausgerückt werden kann.Engaging device for receivers for picture telegraphy with rotating Image drum The invention relates to an Einrückv device for image telegraphy receivers with rotating image drum, through which the axial: feed of the drum while running Drum can be easily engaged and disengaged.

Sie ist auf der Zeichnung in fünf Figuren dargestellt.It is shown in the drawing in five figures.

Fig. i zeigt den Bildempfänger perspektivisch.Fig. I shows the image receiver in perspective.

Fig. 2 his 5 zeigen Einzelheiten der Einrückv orrichtung.Fig. 2 through 5 show details of the Einrückv device.

Die drehbare Bildtrornmzl i ist mit dem Antriebsmotor 2 durch Zahnradgetriebe 3 und d., hohle --1,Zuffen 5 und 6 und Mitnehrnerstangen 7 und 8 gekoppelt. Durch die h-Tuffen 5 und 6 geht eine Welle 9, die auf ihrem mittleren Teile mit Gewinde versehen ist. Auf dem Gewindeteil sitzen Muttern i i und 1.2, die von den Mitnehmerstangen 7 und 8 gefaßt werden und bei stillstehender Spindel o die Trommel i längs der Spindel je nach der Drehrichtung des Motors 2 in der einen oder anderen Richtung axial verschieben.The rotatable Bildtrornmzl i is connected to the drive motor 2 by gear transmission 3 and d., Hollow --1, feed 5 and 6 and Mitnehrnerstangen 7 and 8 coupled. By the h-tuffs 5 and 6 passes a shaft 9 that is threaded on its middle parts is provided. On the threaded part sit nuts i i and 1.2, which are from the drive rods 7 and 8 are taken and when the spindle o the drum i along the spindle depending on the direction of rotation of the motor 2 move axially in one direction or the other.

Für gewöhnlich veranlaßt die Reibung zwischen der Welle 9 und den Muffen 5 und 6, daß von der angetriebenen Trommel i die Spindel 9 mitgenommen wird, so daß Trommel und Spindel sich mit gleicher Geschwindigkeit drehen. Es kann dann keine Axialverschiebung der Trommel i stattfinden. Nun trägt die Spindel 9 am Ende eine Bremsscheibe io:, geben welche durch den Hebel 1:I ein Bremsschuh 13 angedrückt werden kann. Beim Anziehen der Bremse wird die Welle 9 stillgesetzt und die Trommel i durch die starre Verbindung der Bluffen 5, 6 mit den Mitnehmerstangen 7, 8 in axialer Richtung mit Hilfe der lUuttern i i und 12 verschoben. Auf di,seWeise kann also die Längsbewegung der Trommel während ihrer Drehung leicht eingeleitet und zum Aufhören gebracht werden.Usually the friction between the shaft 9 and the sleeves 5 and 6 causes the spindle 9 to be carried along by the driven drum i, so that the drum and the spindle rotate at the same speed. There can then be no axial displacement of the drum i. The spindle 9 now carries a brake disc at the end, which a brake shoe 13 can be pressed on by the lever 1: I. When the brake is applied, the shaft 9 is stopped and the drum i is displaced in the axial direction with the aid of the luuttern ii and 12 due to the rigid connection of the bluffers 5, 6 with the driving rods 7, 8. In this way the longitudinal movement of the drum can easily be initiated and stopped during its rotation.

Die Trommel i befindet sich in einem Gehäuse 15, das mit abklappbaren Seitenwänden; 16 versehen ist, und bewegt sich hinter dem Okular eines Teleskops 17, das in das Gehäuse 15 hineinragt und Licht von einer Lichtquelle 18 auf die Trommel wirft. Dieses Licht wird in bekannter Weise durch die von der Antenne i9 über den Verstärker 20 koininenden Empfangsströme gesteuert.The drum i is located in a housing 15 which has hinged side walls; 16 is provided, and moves behind the eyepiece of a telescope 17, which protrudes into the housing 15 and throws light from a light source 18 onto the drum. This light is controlled in a known manner by the received currents flowing through the amplifier 20 from the antenna 19.

Zur Feststellung des Svnchronnstnus zwischen Sender und Empfänger dient eine auf der Muffe 5 sitzende Kontalztscheibe 2i, die mit einem Isolationssegment 22 versehen ist und mit zwei Bürsten 23 zusammenarbeitet, die mit dein Verstärker 2o durch einen Schalter 2q. und ein Telephon 25 o. dgl. verbunden sind.To determine the synchronization between sender and receiver serves a seated on the sleeve 5 Kontalztscheibe 2i, which with an insulation segment 22 is provided and with two brushes 23 cooperating with your amplifier 2o through a switch 2q. and a telephone 25 or the like are connected.

Die vorn Sender in bekannter Weise erzeugten Synchronisierungsinipulse bewirken rin Telephon 25 zu jeder Zeit eine Anzeige, ausgenommen dann, wenn die Bürsten 23 über (las Isolationssegment 22 schleifen. Wenn die Geschwindigkeit des Motors 2 so eingestellt ist, daß diese Kontaktperiode stets mit den Synchronisierungsimpulsen zusa,inin,2nfällt, entsteht keine Anzeige in dein Gerät 25; dann drehen sich die Sende- und Empfangstrommeln mit derselben Geschwindigkeit. Der Synchronismus zwischen den axialen Verschiebungen der beiden Trommeln ergibt sich aus ihrer gleichen mechanischen Konstruktion.The synchronization input pulses generated by the transmitter in a known manner cause an announcement on telephone 25 at all times, except when the Brushes 23 over (read insulation segment 22 grind. If the speed of the Motor 2 is set so that this contact period always with the synchronization pulses In addition, there is no display in your device 25; then they turn Send and receive drums at the same speed. The synchronism between the axial displacements of the two drums results from their same mechanical Construction.
