 sophisticated recording device,

   as well as an arrangement of circuits allowing control between the recording mechanism and the automatic switches.

  The recording and control mechanism in which the trains of electrical pulses are received, registers them then uses them to activate the automatic switches on the

   This combination provides the desired potential to operate relays 90 t 87. Lc, relay 112 energizes slowly, closing a circuit for 1 <> relay 131 through cam 113 and a resistor. This relay 131 is energized: ntcm; nt, closing a circuit for the relay 132 and parallel to it, a circuit for the relay 120 through the cam 114. This relay 120 completes through the cam 119 1h circuit of the motor electromagnet of the combiner 118 which left position one. When the cama 114?

He marks here on his disk, the first digit of the requested subscriber, causing. series of interrupts of the line corresponding to the marked digit.

 <Desc / Clms Page number 7>

 
 EMI7.1
 These interruptions will cause 107 to neutralize an equivalent number of times. The hardness of the individual pulses is not long enough to allow 112 to break its working contact.
 EMI7.2
 



  The first time 107 closes its normally-closed contact, the following circuit is closed: battery, relay 142, armatures at l "\ jj) OS of 153, of 148 and of. 149, top contacts of 162, relay 120, contacts interiors of 114, armature of 107, and terra. In parallel to this circuit, a resistor with battery is provided which ensures the

   If the number of pulses is greater than four, the pair
