ABSTRACT:
Disclosed herein is an automatically controlled weigh feeding apparatus including a container for prefilling with a substance, a device for discharging the substance from the container at a controllable rate, apparatus for weighing the substance being discharged and for producing an electrical signal proportional to that weight, a voltage to frequency converter connected to receive the electrical signals, a digital computer, apparatus coupled to an output of the voltage to frequency converter for inputting data signals to the digital computer, the computer being adapted to compute a corrective signal based on the input data signals received, and coupling apparatus coupled between the computer and the device for discharging the substance from the container for controlling the rate of discharge responsive to the corrective signal.
