Abstract
In a method and a circuit for controlling an amount of pelletized material that is dispensed from a pellet dispenser, the dispenser is driven at the same speed during each one of a plurality of pellet dispensing cycles. The frequency of dispenser operation is varied by varying the time interval between pellet dispensing cycles. The circuit includes two timers, an OFF timer which is connected to a counter that counts the number of 'off' timing signals in each 'off' period and an ON timer that receives a triggering signal from the counter when the 'off' period is completed. A switch is connected to the counter to select this number of 'off' timing signals. The 'off' time period can also be altered by altering the time base of the OFF timer. This is accomplished with a resistance circuit that is connected to a timing circuit for the OFF timer, through either a user-controlled timer or a temperature-responsive switch.
