Clock relay to expand a

to order the master clock and slave clocks Ulirenanlage

The firing relates to a ührenrelais star extension of a shore to the iiiixadestens a master clock and bucket Number% ^r o2i DTix-ch these main controlled Zeitdienstgerätesi, s "third liebeiiuhren, ordering Uhsrenanlage. Such a clock relay is used Έ, χιν SteneruKg by other time service devices connected to it, see e.g. other lifting clocks, after hating the? from the Ha.uptulix '' koiatiienden love watch control impulses.

depending on the duration or the interval between the incoming impulses, the connected time service devices, d. h, so z. B. slave clocks, time stamps, tower clocks or motorized drives can be adapted. Furthermore, it should be possible to report the operating status of the clock system connected to the clock relay to the controlling master clock or central clock. The known clock relays, consisting of a polarized relay with a central position or two normal relays with blocking cells, cannot meet the above requirements and do not allow the entire clock system to be completely monitored from a central point. ' _: -

To solve the tasks set, the clock relay according to the innovation, which is connected to an Ifeehselstromcfuelle, z. B, the light network, can be connected, characterized in that it has a differential gear, known from drives for external clocks, one input branch of which is driven by a stepping mechanism operated by the pulses from the master clock, the other input branch of which is driven by an electric drive motor in relation to the direction of rotation of the output branch is driven in the opposite direction to this, and whose output branch carries a cam disk which controls an electrical switch - "which switches the drive motor on when the cam disk is twisted out of its zero position and in when the cam disk is reset switches off its zero position again, this drive motor causing the impulses to be sent to the other connected time service devices, e.g. slave clocks, via a switch.

This has the consequence that in the event of failure of the clock relay supplying power source, the impulses coming from the master clock during the downtime by means of appropriate adjustment of the on the: output branch of the gearbox seated cam disk can be saved so that when the power is restored automatically the other connected to the Uh.renrela.i-s Time service devices, e.g. slave clocks, adjusted accordingly will. In doing so, incoming impulses are also taken into account by the master clock during this adjustment process.

because this is about the. an input zx <re ig d® & ~ differential gear, independent of the work of the drive motor in the second drive _{branch s} aiii "the output branch of the differential gear xireiterleites, so that the electric drive motor 'in addition to the current adjustment also the intended by these impulses causes further clock adjustment before it is switched off.

The binary dimensioning is generally made so that one full revolution of this cam disk, which is located on the output branch of the differential gear, corresponds to a full hour. In order to extend the follow-up time to an arbitrarily longer time of, for example, 12 or even e4 hours, possibly even longer, the output branch of the differential gear can drive a double cam disk via a corresponding reduction gear with an integer reduction ratio in a further embodiment of the furnace, which drives the pulse delivery drives the further Seitdienstgeräte in the same "¥ else as the first cam plate, so that therefore, even if this zxieite cam plate is moved ATTs its zero position, the switch is closed and the drive motor, which kept the pulse delivery hervori-runs _ä switched In the case of a desired follow-up time of 12 hours, this reduction gear would have a reduction ratio of 1 i 12, in the case of a desired follow-up time of 2.4 hours, on the other hand, a reduction ratio of 1 s 24.

see an incision in which a spring of the spring set 7 lies normally and leaves the contact 7 open. In order to extend the follow-up time to 12 or Zh hours in the manner explained below, the Q-gear 8 and the cam disk 9 are attached, the slot of which in the zero position corresponds to the in.der disk 6. The spring set 7 is then operated by the two cam disks 6 and 9.

So everyone is on the Lines 2, the incoming pulse is passed on to lines 14. His The duration does not depend on the incoming impulses, but is determined by the speed of the cam disk12, i.e. by the drive lo. Because of the low maintenance, an alternating or synchronous motor or but in connection with the rectifier 15 a controllable direct current motor be applied. "." ■■ "'." ■ _ "

If the Hetz 11 fails for a longer period of time, the disks 6 and 9 continue to rotate as a result of the further impulses coming from 2. If the mains power comes back, the missing pulses are made up in the clock line 14. The 'arrangement extends the subsequent delivery to the impulses which during the catch-up process and? In general, this lag time is sufficient for watches with hour hands up to 12 hours and it would not be necessary to allow 24 hours. For other time service devices, especially those with digital displays or stamps, a follow-up time of 24 hours is required. This can also be easily achieved by changing the translation 8. Likewise, the duration of the pulses and their spacing with the help of the cam disk 12 and their. Translation 16 can be adapted to the connected time service devices. If, for example, in the clock network. 14 tower clocks of the older type with electrical out - _; solution that may require a pulse pause of S-Io seconds, any other follow-up device that works with shorter pauses, as usual, would be useless. It can therefore even be useful to only connect this tower clock with the relay described, so that the clock center can quickly adjust and continue the other clocks and yet it is ensured that the tower clock, which is now important, is made up correctly. To control the network 11 According to the invention, a relay can be attached to the rectifier 15, the working contact of which keeps a closed circuit coming from the control center 2 closed or if no special line is available, then the auxiliary contact can also have a small shunt or earth fault on the control line, which is a sign on the control center triggers. The contact 17 with the resistor 18 would be suitable for this purpose. If the resistance 18 is about the same as that of the slave clock mechanism 3, then in the case of the clock center feeding the lines 2, the earth fault message can easily be determined via 17 and 18 and would provide the information that the mains current was running

has failed. If an earth fault occurs in the clock network 14, it should be address a relay 19, which this initially with the floating power supply 15 still harmless incident with contact 2o in similar Way as with the contact 17 reports. It is then one in due course Review of the clock network 14 is necessary because a subsequent double earth fault is a disturbance due to the increased voltage drop. A one-sided earth fault does not disturb in itselfo

The significantly more important checking of the current to the clock network 14 on Overcurrent, which also occurs in the event of a double earth fault or shunt, is carried out by the further relay 21. For this purpose the relay contains 21 a current winding 21 a, which causes the tightening in the event of overcurrent, with the Contacts 22 and 23 turn off the power to the clock network 14 and with the other Contact 24 also shorts the supply line. Same relay as 21 in the main clock feeding line 2 can then be remedied by the staff the cause of failure. It is important to choose a relay for 21 that picks up faster than the slave clocks in clock network 14 jump. then they stay at the same time. The formation of the 3 contacts 22, 23 and 24 as snap switches already deliver with the first impulse Overcurrent the final "shutdown"

If a voltage winding 21 b is attached to the relay 21, a Response of the relay 21 as a result of an overvoltage from the network 11 and the resulting larger current in the secondary network 14 avoided » Instead of the relay 21, fast fuses with a signaling contact can also be used or relay monitoring can be used.

Since the contact 13 is not operated by a clockwork but by a motor is, a larger switching capacity is available through strong training, the connection of several watch lines - each with appropriate safeguards - Permitted, if not several contacts 12, 13 next to one another be attached to a separation of the secondary clock networks in the pulse pauses 14 to ensure.
