CHARGER_CONTROL_WITH_REFERENCE_BAT_TERY
Developed to insure constant d-c supply for rotary converters if ship's power supply fails. Control circuit operates SW1 at proper time intervals. B2, in series with B1 with polarity opposing, supplies reference voltage. When storage battery needs charge, gas tube ignites to pull in RL and initiate charging cycle.-V. Zeluff and J. Markus, Electronics Manual for Radio Engineers, McGraw-Hill, N.Y., 1949, p 545.
