Abstract: 1496653 Electronic timepieces RANCO CONTROLS Ltd 11 Dec 1974 [12 Dec 1973]  57698/73 Heading G3T A setting circuit for a digital display of a clock has a setting member for causing the display to change and the speed of change increases during the period that the setting member remains in its operated position. The display is operatively connected to up-down counters 11, 12, 13, 14 and counter 11 is supplied on line 15 with count up pulses normally derived from the mains supply through pre-counter circuit 21 which produces a 2 Ásec low pulse from gate 20 every minute. The arrangement of NAND gates 23, 24 ensures that one of the gates 17, 18 is supplied with a high signal and the other with a low signal. The setting controls include a reverse setting button 25, a forward setting button 26 and an enable button 27 which prevents inadvertent setting and operates to enable gates 31, 32 for a time period determined by monostable 35 unless a setting button is operated, in which case a signal through gate 28 keeps monostable 35 reset. The speed of alteration of the display during setting is determined by the output frequency of voltage controlled oscillator 44 which is set by the voltage on capacitor 42. In operation the output of the VCO is fed back through diode 46 so that the voltage input increases to cause the output frequency and thus the setting speed to increase. If the setting button remains operated for a long time the voltage on capacitor 49 may exceed the breakdown voltage of Zener diode 48 causing the setting speed to increase at an even faster rate. When the setting button is released the transistors 50, 51 immediately conduct to discharge the capacitors 42, 49 so that the setting speed is returned to the slow speed to allow the clock to be accurately set. A signal is fed back from the enabling gate 28 to disable the precounter 21 so that after setting, the display will not alter for a basic time unit, i.e. 1 minute.
