Full Title
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 bipolar transistors with internal or external positive feedback > using means other than a transformer for feedback > using at least two transistors so coupled that the input of one is derived from the output of another, e.g. multivibrator
