Filed: 1971-10-21
Abstract: 1324448 Impulse transmitters; sets G W HARRIES 21 Oct 1971 [6 Nov 1970] 49084/71 Headings H4J and H4K In a repertory dialling apparatus multi-digit numbers are stored on strips of paper 55 as spaced black bars 56 which may be produced by typing the letter I or a combination of the letters I and U, and the information is read by a photoscanner 14 containing a photo-transistor 26 which causes a pulse generator constituted by amplifier 31 monostable 32, and driver 33 to pulse reed relay 34 for 33 ms. each time a black bar is scanned, thereby opening relay contacts 35, 36 which are in series with the telephone dial. To make a call the receiver is lifted and the required code is positioned under window 63 by rotating knob 62; dial button 11 is depressed energizing relay 41 which via its contacts 47 reverses the polarity on the rotor 17, thereby forward biasing diode 45. As the motor starts to drive scanner 14, a microswitch 44 inside housing 10 is operated causing contacts 42, 43 to short out diode 45. As each black bar is scanned the output of photo-transistor 26 falls causing relay 34 to be pulsed. Relay 41 is also held on during the dialling sequence. The sequence continues until an extra thick bar 48 is detected which causes relay 41 to de-energize whereby the motor is driven in the reverse direction until the scanner 14 reaches its home position where microswitch 44 is operated to reconnect diode 45 thereby stopping motor 17. A return button 13 is provided which causes an immediate return of the scanning head; a button 12 can be depressed to obviate the need to replace the receiver before redialling if the engaged signal is received. Electro-luminescent diodes 50, 51 are provided to give a visual indication of the dialling operation and of the reply of the called subscriber. A small loud-speaker may be provided in the housing of the dialling apparatus.
