Zusammenfassung:	An automatic liquid level maintenance mechanism employs a probe or plunger for periodically withdrawing a small amount of viscous fluid from the exposed surface of a supply in a container. The fluid thus raised as a "curtain" is allowed freely to fall from the retracted plunger and return to the supply. The liquid curtain is disposed to intercept a light beam which, in the absence of an adequate curtain due to low level of the liquid, is received by a sensor adapted to signal for liquid replenishment.
