ABSTRACT:
A soft dessert dispensing arrangement in which a dispenser is responsive to manual actuation by an operator to dispense soft dessert over a given time period, as measured by an electrical timing circuit. Changes in important parameters affecting the pumping rate of the dessert, such as the pressure and temperature of the pumped dessert and the elapsed time since the last dispensing operation, are compensated for by adjusting the given time period to provide for the dispensing of a substantially constant quantity of dessert despite the changed parameters. The electrical timing circuit is responsive to an input resistance to measure the given time period, and the resistance applied to the timing circuit changes in accordance with sensed variations in the aforementioned parameters.
