Elecraft K2 Battery Charging
... resistor limits charge current. When the battery is fully charged it draws ~15-30mA, so in float charge there will be a ~0.1-0.2V drop over the 6.2Ω resistor. The K2 Battery Charger option specifies a power supply of 14.0V +/-0.2V. There is a Schottky diode in series with the DC power jack for polar ...

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.
