ABSTRACT:
A foam generating unit has a normally lower, tubular generating section provided with a pair of electrodes that expose incoming, foamable liquid to electrolytic action that results in the generation of foam bubbles. The generating section is normally submerged well below the surface of the liquid into which the generator is inserted, and a tubular chimney section attached to and leading upwardly from the upper end of the generating section confines the bubbles as they rise from the electrodes so as to prevent their dispersion into the body of liquids surrounding the generating unit. This aides in the formation of a thick, creamy foam as the bubbles finally emerge from the upper end of the chimney section near the upper surface of the liquid.
