ABSTRACT:
In a liquid dispensing apparatus, a train of control pulses are produced at a rate representative of equal fractional parts of a unit volume of the liquid being dispensed, and for each of these control pulses a divider gates to an output circuit a number of pulses (derived from a continuously-operating generator) digitally equal to the price per unit volume of the liquid being dispensed. The gated pulses appearing in said output circuit are counted in continuous fashion by a counter which, during a sustained operation, produces a resultant output pulse at the conclusion of every one thousand pulses fed to its input. These latter output pulses are fed to decade counters which drive the final display devices for exhibit or indication of the total price.
