Abstract
A control device in which the dispensing of particles from a storage container to a mix is regulated. At predetermined sampling intervals, the concentration of particles in the mix is detected and a signal indicative thereof generated. These signals are summed and processed by a program to develop an actuating signal. The actuation signal energizes the storage container to dispense particles into the mix.
