ABSTRACT:
Precisely recurrently controllable dropwise oilers or other liquid-feeds for apparatus having some optimal-requirement of oil or other liquid-feed to be supplied gravitationally dropwise from an outlet-line emanating from a lofty reservoir. A solenoid actuatable reciprocatable plunger-valve effects intermittent liquid-feed flow along the outlet-line toward a liquid drop-former element spaced a vertical-gap above an apparatus intake-line. For recurring like time-periods, infrared or other electromagnetic detector detects liquid-feed droplets falling from the drop-former so that the liquid-feeder operator might during recurring like time-periods have the solenoid reciprocation adjusted toward the achievement of a dropwise liquid-feed rate tending to converge upon the apparatus optimal-requirement.
