Title: Signal actuated control circuit
Inventor: FAUST CLAUDE MAGNUS
IPC: H04M1/654
Filed: 1961-03-15
Abstract: 940,686. Substation equipment; transistor switching circuits. CODE-A-PHONE ELECTRONICS Inc. March 15, 1961, No. 9404/61. Headings H3T and H4K. A circuit arrangement comprises a circuit element operable as an electric switch and having " on " and " off " conditions, and means which on the receipt by the circuit of a randomly interrupted electric current maintains the circuit element in its " on " condition, the circuit element being switched to its other condition when the current ceases or becomes continuous for longer than respective predetermined intervals of time. The circuit may be used in a telephone answering and recording system in which the recording apparatus is required to be initiated by the receipt of speech signals and to be switched off when the speech is followed by silence or by dialling tone. In the circuit shown, an incoming call connects the negative supply to terminal 14 so that a current flows into the base of transistor 20, so charging capacitors 10 and 24. Transistor 20 conducts to actuate relay 42 and energize the recording apparatus. This condition is maintained for about 15 seconds after which relay 42 drops out unless speech signals are in the meanwhile received at terminals 38 and 40. If such signals are received, they are rectified by diode 36 with such polarity as to cause transistor 26 to conduct. The upper electrode of capacitor 10 falls to earth potential so that its lower electrode goes positive, cutting diode 16 off. Capacitor 24, however, continues to supply current to the base of transistor 20 during the period that speech is being received. Capacitor 10 is discharged through the transistor 26; when a break appears in the speech, transistor 26 switches off and capacitors 10 and 24 are recharged so that current can continue to flow out of the base of transistor 20 when speech recommences. Thus so long as intermittent speech is received transistor 20 remains conductive; when, however, speech ceases altogether capacitor 24 eventually discharges and transistor 20 switches off.
