Title: Frequency adjustment of timekeepers
IPC: H03K23/00
Filed: 1972-10-16
Abstract: 1412779 Electronic timepieces CENTRE ELECTRONIQUE HORLOGER SA 16 Oct 1972 [15 Oct 1971] 47553/72 Heading G3T [Also in Division G4] In an electronic timepiece comprising a timebase oscillator (not shown) feeding a signal I Fig. 2 to a frequency divider 6-9 which produces a timing signal S to operate a display (not shown), a reference frequency e.g. at 0.5Hz from a stable standard frequency oscillator is temporarily applied at X for comparison with the divider outputs to provide a value to be stored in an electrically alterable memory 22-25 in order to adjust the division ratio of the divider so that its output frequency equals the reference frequency. In Fig. 2 the divider outputs Dl to D4 are connected via AND gates 15 to 18 to the memory 22- 25 and to 'modulo two' gates 11-14. The second inputs of gates 11-14 are the outputs of the memory formed by RS flip-flops 22-25 and their outputs together with divider output D5 are connected to an AND gate 19. The output of gate 19 is applied to a monostable pulse generator unit 20 which provides one input to an OR gate 21. The other input of gate 21 is from a monostable unit 27 which receives the reference signal X. The unit 27 output R is also applied to the reset inputs of the memory while OR gate 21 output is applied to the reset inputs of the divider. The reference signal X is also converted by a monostable unit 26 to provide a signal T to the second inputs of AND gates 15-18. In operation, with no reference signal applied, the divider counts pulses I until the count is the same as a binary number - ('1', L 4 , L 3 , L 2 , L 1 ) - partially contained in the memory. At this instant the comparison circuit formed by the 'modulo two' gates 11-14 resets the divider to zero. The division ratio is thus equal to ('1', L 4 , L 3 , L 2 , L 1 ) and is not modified. The outputs R, T of the monostable units 26, 27 are zero. When the reference signal X is applied and when it switches from '0' to '1' monostable 27 applies a pulse to divider 6-10 and memory 22-25 to reset both to zero. While the reference signal has a value '1', the dividers count the pulses I. When X switches from '1' to '0' (i.e. trailing edge of reference signal pulse), the content of the dividers is transferred by AND gates 15-18 into the memory, then the divider 6-10 is reset to zero. The memory is not reset and stores the values of the outputs of respective dividers at the end of the standard counting period. The content transferred is equal to the number of pulses I which occurred during the application of the value '1' of the reference signal. This is the desired value of the division ratio. Temperature compensation of the timebase oscillator may be provided, Fig. 4 (not shown). In an alternative embodiment, Fig. 5 (not shown), a pulse inhibit circuit is connected between the timebase signals I and the divider and is arranged to inhibit a number of pulses I equal to the content of the memory.

A method of forming metal articles by means of shock waves generated in water comprises a capacitor the charge on which is discharged across an electrode gap situated in the water thereby producing the shock waves. A metal blank to be formed is placed in a die having two parts 18, 22 the part 18 being advanced towards or retracted from, the part 22 by means of an hydraulic system which includes a piston 34 travelling in a cylinder 33, the hydraulic pressure being produced by a pump 35 and admitted to either end of the cylinder as required by a solenoid-operated valve 37 by way of hydraulic lines 38, 39. When the die parts are closed to clamp the metal blank and sufficient pressure is developed against the piston 34 a pressureactuated switch 47 closes to actuated valves 60, 67; the valve 60 admitting water to the chamber 23 whilst the valve 67 allows the chamber 19 to be evacuated of air. The bank of capacitors is then charged from an electrical source and then discharged across an electrode gap 54 situated in the water chamber 23 thereby to produce shock waves in the water in the chamber 23 to form the metal blank into the desired shape. The system comprises an interlocking electrical relay system to ensure that the sequence of operations in the forming of the blank occur in the required order and that should any malfunction occur at any stage the system fails safe. Means are also provided to stop the operational sequence at any point therein should this be desired. In another embodiment part of the relay system is replaced by a series of camoperated switches.

Abstract: 1468716 Amplifiers; pulse circuits COMMISSARIAT A L'ENERGIE ATOMIQUE 22 Nov 1974 [27 Nov 1973] 50631/74 Heading H3T A charge preamplifier for low noise use, e.g. with a lithium-drifted silicon X-ray detector 6, comprises an input stage connected to an amplification stage connected to an output stage 14, and an optoelectronic negative feedback circuit, the input stage comprising a cooled first FET T 1 <SP>1</SP> illumination of which closes the feedback circuit, the load of T 1 <SP>1</SP> being provided by a second FET T 2 <SP>1</SP> connected in series with a coil L 1 . To reduce noise current fluctuations the impedance of L 1  should be large compared with the reciprocal of the slope of T 2 <SP>1</SP>. The amplification stage is constituted by differential circuit T 3 <SP>1</SP>, T 1  feeding into T 2 , the load for which is T 3 . Bias voltages for the output transistors T 4 , T 5  are determined by diodes D 1 , D 2 , D 3 . A low pass filter R 8-10 , C 6  corrects the frequency response of the amplifier. The analogue output at S passes via T 6  to a hysteresis comparator M 1 ; when the output voltage exceeds a threshold set by P 2  and P 3 , M 1  delivers a logical "0" signal to a NOR gate M 2  the other input of which receives the signal integrated by circuit 16. After a delay due to 16, M 2  delivers a logical "1" to bi-state circuit 20 which turns on T 9 , which supplies electroluminescent diode D 4 . The radiation emitted by D 4  falls on the gate junction of T 1 <SP>1</SP> and increases its reverse current causing a feedback capacitor C 8  to discharge until the output voltage of the preamplifier falls to the lower threshold of M 1 . The temperature of T 1 <SP>1</SP> in cryostat 7 is determined by the current through a Zener diode Z 1 , R 28  being chosen so that the noise voltage at S is minimized. As an alternative to pulsed operation the preamplifier may be operated with the circuit 20 as a class A differential stage, with the base of T 7  directly connected to S, and T 1 <SP>1</SP> continuously illuminated by D4.
