  • Patent number: 4350243
    Abstract: A material dispensing apparatus including drive structure for driving a feeder bowl is disclosed. A control circuit for controlling the drive includes a Hall effect amplitude sensing transducer for monitoring the magnitude of bowl vibrations and a braking circuit for controlling the damping of vibratory motion after the requisite amount of material has been fed from the feeder bowl. The braking circuit selectively reverses the current flow through a drive coil which comprises a portion of the drive circuitry of the apparatus. This current reversal disrupts the rhythm of forced oscillations which feed material from the bowl and causes bowl motion to be damped.
