decatron
The decatron is a two-pulse OG-4.
Countable for work in calculating and calculating-solving devices and for division
frequencies.The cathodes are cold and inactive.They work in any position.
The indication is made through the dome of the cylinder. The decoration is glass, with a base (RSH5-1).
The two-pulse decatron contains a disk anode, around which the cathodes are located,
divided into three groups: indicator cathodes, first subcathodes and second subcathodes.
The cathodes of the same name are connected in the device into cathode rings. One of the indicator cathodes
– the main one serves as an output electrode and has a separate output.
A positive voltage relative to the indicator cathodes is applied to the decatron anode,
and for the first subcathodes – a positive voltage of about 50 V.
In the initial position, a glow discharge exists between the anode and the main cathode.
The two-pulse decatron OG-4 is reversible: with its help, you can not only summarize,
but also subtract incoming pulses if the first pulse is fed into the chain of the second subcathodes,
and the second is in the chain of the first.
