Title: Electronic timepieces
IPC: G04G3/02
Filed: 1972-04-13
Abstract: 1370564 Electronic timepieces EBAUCHES SA 13 April 1972 [22 April 1971 ] 17013/72 Headings G4D D6Y D6C1 D6C2 and D7X To permit adjustment of the rate of an electronic timepiece having a Piezo-electric oscillator as time base and a frequency division chain controlling a time display H, means are provided to adjust the scale of division comprising a digital comparator for comparing the logic state of a binary reference of M bits with that of stages N+I to N+M of the division chain. The comparator has a blocking input BLO which receives the output Q from a flip-flop FFC which is controlled alternately by the outputs of the comparator and the division chain. When the comparator input is blocked, the division chain counts up to the limit of its flip-flop stages FFD whereupon monostable multi-vibrator MONO 1 emits a pulse which actuates the display H and clears FFC, thus reducing output Q to zero and unblocking the comparator. During the next period of division, when the comparator senses that the contents of stages N+I to N+M are equal to the binary reference number K, it emits a signal to the SET input of FFC so that output Q changes to the value 1. The comparator is thereby blocked and monostable multi-vibrator MONO 2 caused to emit a pulse, resetting the divider stages to zero. The binary reference source may comprise a set of M switches Fig. 2 (not shown) or an electronic memory e.g. a shift register.

Title: Improvements in or relating to circuit arrangements responsive to the phase relationbetween pulse sequences
IPC: G01R25/00
Filed: 1952-07-07
Abstract: 700,287. Automatic phase control systems. TELEFUNKEN GES. FUER DRAHTLOSE TELEGRAPHIE. July 7, 1952 [July 7, 1951] No. 17076/52. Class 38 (4). [Also in Group XXXVI] A circuit arrangement for producing a control or measuring potential representative of the phase relation of pulses of successively opposite polarity from lines P1, P2, Figs. 5, 6, includes two rectifiers D11, D12 connected in series in the same direction of conductivity and a condenser C10 connected to their junction point charged and discharged by the pulses through the rectifiers, the voltage across the condenser being applied to a valve circuit of high input impedance adapted to produce an output voltage dependent upon the peak potential of the input wave form. In Fig. 5, the values of the grid condenser and leak are such as to produce a time constant large compared to the time duration of a pulse. The pulses from P1 charge the condenser C10 in one direction and those from P2 in the opposite direction, the consequent voltage wave across the condenser being dependent on the phase relation of the two sets of pulses. The output voltage is measured by an indicating or recording instrument MR, a resistance R1 compensative for the feed current of the valve 1. In Fig. 6, the diode circuit D11, D12, C11, C12, C10, R11, R12 is duplicated at D21, D22, C21, C22, C20, R21, R22, as also is the valve circuit. The two valves 1, 2 may be in a single envelope as shown. The diodes D21, D22 are connected in the opposite sense to the diodes D11, D12 so that equal voltages of opposite polarities are produced on the condenser C10, C20. The valves 1, 2 feed a polarized relay PR which may control a motor to maintain a desired phase relation between the pulse sequences. Alternatively as in Fig. 8 the valve 2 is fed from a separate source N and the control voltage is obtained as the difference between the voltage drops in cathode resistances KR1, KR2. This may be fed to a reactance valve to maintain the desired phase relationship. The two series of pulses may be applied to a common input connected to both of the rectifiers which are connected in the same direction of conductivity.

Title: Shock dampers for automobiles
IPC: F16F9/44
Filed: 1939-06-10
Abstract: 530,522. Shock-absorbers. MARTINDALE, A. F. June 10, 1939, No. 17102. [Class 108 (iii)] In an automobile shock absorber the damping is varied automatically by means displaced by a moving part of the shock-absorber this automatic action being under manual control. In the construction shown diagrammatically in Fig. 1 applied to an hydraulic shock-absorber A, B the damping is controlled by a valve C loaded by a spring C<SP>1</SP> seated against a plunger D which bears on a lever D<SP>1</SP> operated by a cam F on the rocker shaft E<SP>1</SP> of the shock-absorber. The upward movement of the plunger D and lever D<SP>1</SP> is controlled by a cam G connected by a spring G<SP>1</SP> to a manually-operated lever G2. If the manual control is altered the spring G<SP>1</SP> is stressed, and when the plunger D is next depressed by the cam F the spring rotates the cam to a new position, so that when the plunger is returned by its spring C<SP>1</SP> it returns only to the new position set by the cam and the manual control. In a modification the manual control acts through a spring on a sliding bolt having two steps either of which can engage the end of the lever D<SP>1</SP> and thus provide two settings for the plunger. The invention is applicable to solidfriction shock-absorbers.
