... Multivibrators are circuits with one or more stable states. There are 3 common varieties of multivibrators: 1) Monostable multivibrators (one shot) have one stable state. If the circuit is forced out of its stable state (by e.g. an input pulse) it eventually returns back to the stable state by itsel ...

Metadyne
A metadyne is a direct current electrical machine with two pairs of brushes. It can be used as an amplifier or rotary transformer. It is similar to a third brush dynamo but has additional regulator or ""variator"" windings. It is also similar to an amplidyne except that the latter has a compensating winding which fully counteracts the effect of the flux produced by the load current. The technical description is ""a cross-field direct current machine designed to utilize armature reaction"". A metadyne can convert a constant-voltage input into a constant-current, variable-voltage output.
