Abstract
989,111. Dictation systems. SUD-ATLASWERKE G.m.b.H. March 26, 1962 [Aug. 11, 1961], No. 11507/62. Heading H4K. In a private telephone system which includes a position equipped with dictating machines, the connection to such a machine is prevented except when it is ready for dictation. A slider 10 movable on a shaft 14 is coupled to the recording and playback head. During recording the slider 10 pushes an auxiliary slider 11 in front of it, contacts 25 being closed and retained by a magnet 12 on the slider 11. When playback is initiated, the magnet 12 is released and the slider is moved backwardly with the head over the recorded matter, the movement being limited by a stop 16, which when engaged opens contact 15 to disable the driving magnet. A braking magnet 13 fixes the auxiliary slider 11. If the dictator hangs up before playback is complete, the slider 10 continues its movement with the head until it again reaches the slider 11, when contacts 25 reclose. Moreover, a magnet 24 energizes and allows the stop 16 to follow and re-engage the slider 10, so that further playback of the recorded matter is prevented. A thermal relay operates after an interval and allows reseizure of the dictating machine. The control circuits of the machine are described, Figs. 2, 4 (not shown).
