摘要

The automatic dispensing machine is for beer and other effervescent drinks, filling glasses with fluid to a predetermined level, and with froth, also to a predetermined level. It has level-measuring devices reacting differently to froth and fluid and feeding electrical switchgear, so as to control the filling operation in stages. The filling operation can be interrupted for an adjustable period when the top measuring device, reacting to froth, operates, and the operation is automatically ended when the lower measuring device operates, on the fluid reaching the desired level.
