Abstract
Improvements in the display devices of incoming calls for telephone subscriber apparatuses, in which said visualization is carried out by means of the blinking of a neon lamp, which is characterized by including in its signaling circuit an electrical device formed by a capacitor (c ), which will be charged in the corresponding half-cycles of the call current; a diode (d), which derives the call current in those half-cycles in which the capacitor c is charged; and a neon lamp (n), which will be displayed on the half-cycles of the call current in which the capacitor c is discharged. All of this as shown in fig. 2 that is accompanied, connected and functioning as described in fig. The memory that precedes. (Machine-translation by Google Translate, not legally binding)
