Today in 1977, US Patent 4011896 A was issued, an invention of John W. Nilon and Thomas J. King, for their “Apparatus for Rapidly Dispensing Beer into Open Cups.” Here’s the Abstract:
Beer is stored in vessels located in a refrigerated storage area before passing through dispensing lines connected to a plurality of dispensing taps. The dispensing lines are maintained in heat-exchanging relationship with cooling apparatus which further depresses the temperature of the beer below that of the refrigerated storage area. By the time the beer reaches the cooling taps, the temperature of the beer is sufficiently depressed so as to permit the beer to be dispensed at a high rate into drinking containers which pass beneath the taps.
