Title: Improvements in electrical signalling apparatus
IPC: G08B3/10
Filed: 1927-11-11
Abstract: 281,265. Magneta Suisse Soc. Anon. Nov. 27, 1926, [Convention date]. Order apparatus.-In the transmitter of an electric signalling system, the depression of a key corresponding to the desired signal sets in motion a spring-driven disc which interrupts or reverses the line current until it is arrested by a stop engaging the depressed key. The signal keys are mechanically interlocked with a returnto-zero key, which arrests the disc in its normal position. The spring may be rewound automatically by a motor the circuit of which is permanently closed or by hand. Just before the disc 5, Fig. 5, is arrested, a contact on it engages the depressed signal key to close at 26 the circuit of a relay 63 controlling auxiliary audible signals near the ratchet-operated visual indicators 59; the circuit of relay 63 may also be closed by a key 47. The signal keys 33, Fig. 2, slide in holes in the front plate 36 and a plate 35, and are formed with collars 37 adapted to engage a movable plate 38 whih is connected by a lever 45 to the return-to-zero key 43 in such a way that when any signal key is depressed the return-tozero key is restored, and vice-versa. The spring motor is re-wound by an electric motor 10 until the driving spring has a tension which balances the torque of the winding motor and is damped by a metal disc 12 rotating in the field of a permanent magnet 13. The disc 5 is normally held by the engagement of the stop 25 with the depressed return-to-zero key 43. The depression of a signal key 33 tilts the plate 38 to restore the key 43, thus releasing the disc 5 which rotates until the stop engages the depressed key 33, the undulations on the edge of the disc causing the springs 20, Fig. 5, to reverse the connection of the battery 52. to the line 57. The transmitter is returned to normal by depressing the return-tozero key 43, but a second signal, subsequent to the first, can be given without returning the transmitter to normal by depressing the returnto-zero key to release the first signal key and then immediately depressing the second signal key which arrests the disc before it reaches the normal position. In the modification shown in Fig. 7, the driving spring 80 is re-wound by the knob 71. The spring 80 is connected by gearing 78, 77 to a wheel 73, which is loose on the spindle 70 and carries a ratchet 74 engaged by a pawl 76 pivoted on the casing so as to prevent backward rotation of the gearing 73, 77, 78. The wheel 73 also carries a pawl 75 engaging a ratchet 72 on the spindle 70, the rotation of which by the knob 71 is limited by a stop to half a revolution. A spring 81 returns the spindle 70 to normal after each actuation. A cam 68 on the spindle 70 co-operates with a lever 45 to restore a depressed signal key 33 as in the first modification, and also controls a pin 67 which arrests the disc in its normal position.

Abstract: 1398827 Electronic timepieces - DAINI SEIKOSHA K K 27 June 1973 [10 July 1972] 30519/73 Heading G3T [Also in Division H1] In an electronic timepiece comprising a quartz crystal controlled oscillator 20 Fig. 4, a frequency divider 21 and a logic gate 26 which in normal operation of the timepiece passes pulses from the divider to a driving circuit 22 to operate a time display device 23, logic circuits 24 to 27 are controlled by manually operated switches S 1 , S 2  enabling the time displayed to be corrected by adding pulses to or blocking pulses from output 26a of the gate 26 for driving the display. In normal operation of the watch the switches S 1 , S 2  are open. When switch S 2  is closed a control circuit 27 causes the minus correction gate 26 to block pulses to the driving circuit. Thus the display will be retarded for a predetermined unit of time, e.g. 'n' secs or 'n' mins, which is a function of the period of the timing signal pulses from the divider 21. With S 2  open and S 1  closed, a control circuit 25 enables a plus correcting gate 24 to apply an output signal to the driving circuit in addition to the timing signal passing through the minus gate 26; whereby to advance the display by a predetermined unit of time, which is a function of the period of a pulse of the timing signal. The amount of correction may be a whole number of minutes or seconds. The display may comprise hands or be digital as Fig. 9. In one embodiment Fig. 1 and Fig. 2 (not shown) the switches are operable by means of an axially and angularly moveable stem 1. When the stem is rotated it rotates a pinion 3 via a clutch wheel 2. Integral with the pinion 3 are insulating pawl wheels 4, 5. A contact spring 6, having one end fixed and the other end inserted between teeth (4a) Fig. 3 (not shown) of pawl 4, and a pin 10 constitute the switch S 1 . A contact spring 7, having one end fixed and the other end inserted between teeth (Sa) (Fig.3) of pawl 5, and a pin 11 constitute the switch S 2 . Rotation of the stem in direction A closes switch S 1  and opens switch S 2  and vice-versa when the stem is oppositely rotated. When the stem is moved axially outwards from its time correcting position the clutch is disengaged from pinion 3 and engages with a setting wheel for adjustment of the day and date or minute wheel. Thereby the hour and minutes hands may be corrected in a conventional manner. In a digital watch Fig. 9 also Figs. 10, 11 (not shown) a push-button switch S 3  serves in conjunction with a controller (38) detailed (Fig. 11) to alter the function of correction switches S 4 , S 5 . Thus in one position of S 3  the letters 'HOUR' and 'MIN' are displayed and operation of S 4 , or S 5  causes the hours or minutes respectively to be corrected. In the other position of S 3  the symbols '-1' and '+1' are displayed, and operation of S 4  and S 5  causes adjustment of the time displayed by a unit of time - 1 or +1 respectively. For instance it may be arranged that operation of S 4  causes the time to be delayed by 1 sec while S 5  causes it to be advanced by 1 sec.
