Zusatz zum Patent 393695.Addendum to patent 393695.

Patentiert im Deutschen Reiche vom 25. Januar 1923 ab. Längste Dauer: 31. Mai 1939.Patented in the German Empire on January 25, 1923. Longest duration: May 31, 1939.

Wenn' bei der in der Patentschrift 393695 beschriebenen Einrichtung zum wahlweisen Anruf von Stationen für (Radio-) Telegraphie und Telephonie in einer Empfangsstation ■5 während des Anruf Vorganges der Gleichschritt verlorengegangen ist, so kommt die Bürste B nach Aufhören der von der Sendestation ausgehenden Impulse nicht im Ausgangspunkt, sondern an einer andern Stelle der Scheibe zum Stillstand. Der für dasIf 'in the device described in the patent 393695 for the selective calling of stations for (radio) telegraphy and telephony in a receiving station ■ 5 the lock step has been lost during the calling process, the brush B comes after the impulses emanating from the transmitting station have ceased not at the starting point, but at another point on the disk to a standstill. The one for that

richtige Arbeiten notwendige Gleichschritt wird durch die nachstehend beschriebene, in der Zeichnung in beispielsweiser Ausführung schematisch dargestellte, selbsttätige Korrektionsvorrichtung wiederhergestellt.Correct work necessary lock step is described below, in Automatic correction device shown schematically in the drawing in an exemplary embodiment restored.

Auf der Scheibe ist ein Schleifring angebracht, der bei c um die Breite eines Kontaktstückes unterbrochen ist. Diese Stelle fällt mit dem Ausgangspunkt der Bürste B zu-A slip ring is attached to the disk, which is interrupted at c by the width of a contact piece. This point coincides with the starting point of brush B

sammen. Das Verzögerungsrelais VR ist einerseits mit dem Schleifring, anderseits mit dem Ruhekontakt b des Empfängerrelais ER verbunden. Bleibt nun die Bürste B, wie oben erwähnt, infolge Störung des Gleich-Schrittes nicht am Ausgangspunkt bei c stehen, so kommt folgender Stromlauf zustande: Batterie, Bürste B, Schleifring, Verzögerungsrelais VR, Ruhekontakt b des Empfängerrelais ER, Batterie. Der Anker vontogether. The delay relay VR is connected on the one hand to the slip ring and on the other hand to the normally closed contact b of the receiver relay ER . If , as mentioned above, brush B does not stop at the starting point at c as a result of a disturbance in the equal step, the following current flow occurs: battery, brush B, slip ring, delay relay VR, normally closed contact b of the receiver relay ER, battery. The anchor of

ao VR schließt den Stromkreis des Fortschaltmagnets FM, dessen Anker mit Selbstunterbrechung versehen ist. Die Bürste B bewegt sich schrittweise weiter bis zum Ausgangspunkt; hier bleibt sie stehen, da durch denao VR closes the circuit of the stepping magnet FM, the armature of which is self-interrupting. The brush B continues to move gradually to the starting point; here it stops, there through the

as Ausschnitt am Schleifring bei c der Stromkreis des Verzögerungsrelais VR unterbrochen und hierdurch der Fortschaltmagnet FM stromlos wird. Damit ist der Gleichschritt für den nächsten Anruf wiederhergestellt. Während des Anrufvorganges wird in den Pausen zwischen den einzelnen Impulsenhe section of the slip ring at c, the circuit of the delay relay VR is interrupted and the stepping magnet FM is de-energized as a result. This re-establishes lockstep for the next call. During the call process, there is a pause between the individual impulses

der Stromkreis von VR geschlossen; auf die kurzen Stromstöße spricht das Verzögerungsrelais jedoch nicht an; die langen Impulse, welche zur Herstellung der Nummernkombi- 35 nation dienen, erreichen VR nicht, weil beim Eintreffen der Impulse der Anker des Empfängerrelais ER sich an den Arbeitskontakt α legt.the circuit of VR closed; However, the delay relay does not respond to the short current surges; the long pulses that are used to produce the number combination do not reach VR because when the pulses arrive, the armature of the receiver relay ER is placed on the normally open contact α.

Patent-Ansprüche:Patent Claims: 1. Einrichtung zum wahlweisen Anruf von Stationen für (Radio-) Telegraphic und Telephonie nach Patent 393695 mitselbsttätiger Korrektionsvorrichtung, dadurch gekennzeichnet, daß ein mit einem Ausschnitt (bei c) versehener Schleifring so angebracht ist, daß die umlaufende Bürste (B) über den Schleifring den Stromkreis eines (Verzögerungs-) Relais, das beim Ansprechen den Fortschaltmagnet in Tätigkeit versetzt, dann schließt, wenn sie den Ausgangspunkt ihrer Bewegung verlassen hat.1. Device for optional calling of stations for (radio) telegraphic and telephony according to patent 393695 mitselbsttätiger correction device, characterized in that a slip ring provided with a cutout (at c) is attached so that the rotating brush (B) over the slip ring the circuit of a (delay) relay, which, when activated, activates the switching magnet, then closes when it has left the starting point of its movement. 2. Korrektionsvorrichtung nach An-Spruch i, dadurch gekennzeichnet, daß das Relais (VR) über den Ruhekontakt (b) des Empfangsrelais (ER) Strom erhält und als Verzögerungsrelais ausgebildet ist, so daß es nur dann anspricht, wenn mit Beendigung des Anrufvorgangs das Empfangsrelais stromlos wird.2. Correction device according to claim i, characterized in that the relay (VR) receives power via the normally closed contact (b) of the receiving relay (ER) and is designed as a delay relay so that it only responds when the call process ends Receiving relay is de-energized.
