CPC: by the use, as active elements, of gas-filled tubes, e.g. astable trigger circuits (H03K3/55 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Circuits for generating electric pulses; Monostable, bistable or multistable circuits > Generators characterised by the type of circuit or by the means used for producing pulses > by the use, as active elements, of gas-filled tubes, e.g. astable trigger circuits

CPC:

Circuits for generating electric pulses; Monostable, bistable or multistable circuits (H03K4/00 takes precedence; for digital function generators in computers G06F1/02) > Generators characterised by the type of circuit or by the means used for producing pulses (H03K3/64 - H03K3/84 take precedence) > by the use, as active elements, of gas-filled tubes, e.g. astable trigger circuits (H03K3/55 takes precedence)
