SU20552A1 - Device for increasing the duration of contact in electric clocks - Google Patents

Description

The present invention consists in the fact that S is a device for increasing the duration of a co-tact in an electric clock with a metal disc rotating a electromagnet rotating in a yole - the winding of this electromagnet is connected to the secondary clock circuit directly or connected to the battery via a relay, also connected to the secondary clock line As a result, the electromagnet winding and the current is received only at the moment of sending emulsions.

The drawing shows a diagram of the irradiation.

The ring-shaped iron core 5 c; the winding 4 is carried by itself. Between the ends of the core there is a metal disk 1 mounted on the axis 8 of the primary electric clock. In the windings 4, the resistance 5 is turned on. When winding 4 is turned on, the disk 1 interacting with the magnetic field will experience a braking effect and thereby lengthen the contact time, and both the braking effect and the contact time will depend on the current strength in the winding. Co-motivation 5 makes it possible to vary the strength of the current and to obtain the necessary degree of contact delays in each case. Winding 4 is included in the secondary clock circuit for the same purpose, so that this winding is energized only at the moment of pulsing.

In order to increase the number of connected secondary clocks and unload the contacts of the primary clocks, winding 4 cannot be connected directly to the secondary clocks, but connected to the battery 8 through the contacts 7 of the relay 6 connected to the secondary clocks. In this case, the operation of the device remains the same, but the winding of the relay 6 and the consumption gap is much smaller than the current 4, and thus the contacts of the primary clock are respectively unloaded. In order to further unload the primary clock, an electromagnet that serves to wind up the weights or springs of the clock mechanism, which can usually be switched on to the secondary clock of the secondary clock, can be included in the circuit of the battery 8 parallel to the winding 4.

The subject of the patent.
