Abstract

452,495. Automatic exchange systems. SZANTO, L., 7, Istvan ut, and GERO, I., 33, Vilma kiralyno ut, both in Budapest. Nov. 21, 1934, No. 33468. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 23, 1935]. [Class 40 (iv)] In an exchange system using automatic ringing-apparatus the calling subscriber receives verbal announcements while the called subscriber is being rung either from a microphone or from any type of phonographic machine. Preferably the announcements are given in the silent periods only and the ringing interrupter may be coupled to the phonographic driving arrangements. As shown, however, a telegraphone C for giving the announcements is common to several offices and synchronism is achieved by latching the interrupter shaft 11 at the end of each revolution and unlatching it by a signal from the telegraphone driving mechanism, the signal being sent over one wire of the junction 23 coupling the exchange in which the telegraphone is situated with the exchange to which subscribers A, B are connected.
