Abstract

Peristaltic Voltage Blocks Abstract of the Disclosure A coating material dispensing system comprises an electrostatic high potential supply having an output terminal on which the supply maintains a high electrostatic potential, a source of coating material, and a dispenser for dispensing the coating material. The output terminal is coupled to the dispenser to supply potential to the coating material dispensed by the dispenser. A peristaltic device couples the dispenser to the source of coating material. The peristaltic device has a length of resilient conduit and contactors for movably contacting the length of resilient conduit at multiple contact points for substantially dividing the coating material in the peristaltic device into discrete slugs of coating material substantially to interrupt the electrical path through the coating material from the terminal to the coating material source. The peristaltic device includes an inlet end for coupling to the source of coating material. The length of resilient conduit has a first inside transverse sectional area at a first location along its length when it is filled with coating material at the first location and a second inside transverse sectional area larger than the first at a second location along its length further from the inlet end than the first location when it is filled with coating material at the second location.
