 kommt dann ein Strom zustande von Erde über T, a1, h2, u2, M1, U2, Batterie ; durch den Gegenstrom in U2 wird U aberregt, u1 und u2 werden geöffnet. 



   H ist ein Verzögerungsrelais und die Verzögerung des   Ankerabfalles   ist so gross, dass erst   Ma   geöffnet wird. bevor h2   sieh öffnet,   Wenn aber ha geöffnet ist und beim nächsten   Stromstoss ! 7   erregt und u2 wieder geschlossen wird, so geht der   Stromstoss   über den Kontakt   a4 und   die Wicklung 3 von B. B schliesst sweine Wicklung 3 durch bl kurz, schaltet seine Wicklung   4   durch b3 
 EMI2.2 
 durch Öffnen von p wird eine weitere Stromstossgabe verhindert. 



   Sollte nicht die Taste 7, sondern erst die Taste 30 gedrückt sein, so würde das Relais P trotz Erregung des Relais B nicht erregt werden. Es wiederholen sich dann die Arbeitsvorgänge, 
 EMI2.3 
 kurzgeschlossen werden.

 EMI2.1
 then a current comes from earth via T, a1, h2, u2, M1, U2, battery; U is de-excited by the countercurrent in U2, u1 and u2 are opened.



   H is a delay relay and the delay in armature dropout is so great that Ma is only opened. before h2 see opens, but if ha is open and at the next power surge! 7 is energized and u2 is closed again, the current surge passes through contact a4 and winding 3 of B. B shorts winding 3 through bl, switches its winding 4 through b3
 EMI2.2
 opening p prevents another surge of current.



   If button 30 and not button 7 were pressed, relay P would not be energized in spite of energizing relay B. The work processes are then repeated,

 be short-circuited.

PATENT-ANSPRÜCHE : 1. Impulssender für. selbsttätige Fernsprechanlagen nach Patent Nr. 63771, gekennzeichnet durch die Anordnung einer einzigen Stromstosseinrichtung zum Betrieb der nacheinander zu erregenden Sehaltrelais (I, II Impulssender nach Anspruch 1, dadurch gekennzeichnet, dass die Schaltrelais über eine einzige Erregerleitung (Lf,) erregt werden, wobei jedes Schaltrelais zwar vom vorhergehenden Schaltrelais an die gemeinschaftliche Erregedeitung angeschaltet, am Ansprechen aber solange verhindert wird, bis der Stromstoss für das vorhergehende Schaltrelais verschwunden und ein neuer Stromstoss abgegeben ist. PATENT CLAIMS: 1. Pulse transmitter for. Automatic telephone systems according to patent no. 63771, characterized by the arrangement of a single current impulse device for operating the successively energized vision relays (I, II impulse transmitter according to claim 1, characterized in that the switching relays are excited via a single excitation line (Lf,), each Switching relay is switched on from the previous switching relay to the common excitation line, but is prevented from responding until the current pulse for the previous switching relay has disappeared and a new current pulse has been delivered.
