ABSTRACT:
The invention provides, among other things, bead dispenser for holding a charged bead and selectively dispensing the bead, the dispenser comprising: (a) a feeder channel having a lower outlet; (b) a bead selection escapement with a depression having an outer lip and located below the first lower outlet such that a bead exiting the lower outlet comes to rest in the depression; (c) a dispenser channel descending from the level of the lip, wherein the lip impedes a bead situated on the bead selection escapement from entering the dispenser channel; and a first dispensing electrode for creating an electromagnetic potential to pull or push the bead over the rim and into the dispenser channel.
