Abstract: A remote low voltage power source for electrostatic paint applicators used in hazardous locations. A low voltage generator and voltage conditioning and regulating circuitry are mounted in a small explosion proof housing. A generator shaft and a shaft on a voltage level adjusting potentiometer extend through and projects from the housing. The flamepath and the flame gap for the shafts meet explosion proof standards while permitting shaft rotation. An air driven turbine is mounted on the exterior of the housing and is connected to the projecting generator shaft to drive the generator. The low voltage is applied to a spray gun which includes circuitry for increasing the voltage to a high level for electrostatic charging sprayed paint.

Abstract: An electrically non-insulative, typically metal, atomizer bell is housed in a shroud-like housing. A prime mover, such as an air turbine motor, typically also housed in the housing, rotates the bell to atomize coating material delivered to the bell. A second shroud movable relative to the bell has a first, retracted orientation in which the second shroud does not shield the charging portion from the approach of articles to the bell and a second, projected orientation in which the second shroud does shield the bell from the approach of articles to reduce the likelihood of disruptive electrical discharges from the bell.

Abstract: A resistor housing includes passageways to accommodate high potential electrical connectors. Connection is made from one of the connectors through a high voltage cable assembly to one output of a power supply. The cable assembly includes a length of high voltage, high-flex, shielded coaxial high voltage cable. The center conductor of the cable is finished at both ends with a banana plug. The shield of the cable is terminated. A sleeve of, for example, heat-shrinkable semi-rigid, multiple wall polyolefin, is slipped onto the stripped end of the cable over the exposed shield and the end of the cable jacket. A length of heat-shrinkable tetrafluroethylene (TFE) is slipped over the sleeve and the adjacent region of cable jacket, shrunk, and trimmed flush with the end of the polyolefin sleeve. Paint or solvent from a trigger/dump/solvent manifold is supplied through a feed tube. The feed tube is constructed from an electrically non-conductive material. Toward the feed tube's distal end, an electrically conductive pin is press fitted into a passageway which extends transversely across the longitudinal extent of the feed tube. Coating material passing through the feed tube is charged as it passes the pin owing to the close spacing of the ends of the pin to a rotary atomizer drive shaft through which the feed tube extends.

Abstract: A rotary atomizer includes an inside surface onto which a coating material is deposited, an opposite outside surface and a discharge zone adjacent the rotary atomizer's inside and outside surfaces, coating material being discharged from the discharge zone. A housing substantially surrounds and houses the rotary atomizer except for a region of the rotary atomizer adjacent and including the discharge zone. The housing includes an inside surface, an outside surface and an opening adjacent the inside and outside surfaces of the housing. The inside surface of the housing and the outside surface of the rotary atomizer are treated so as to render them electrically non-insulative. An electrostatic potential difference maintained across the electrically non-insulative inside surface of the housing and an article to be coated by material atomized by the rotary atomizer causes charge to be transferred from the electrically non-insulative inside surface of the housing to the outside surface of the atomizer.

Abstract: A method and system for supplying electrically conductive coating materials to an electrostatic dispenser with a parallel arrangement of subsystems selectably coupled to the dispenser by a four-port system voltage blocking valve, which electrically isolates the subsystems. The subsystems each include first and second piston cylinders that alternatingly receive a selected coating material from a corresponding manifold and supply the coating material to the dispenser by a subsystem voltage blocking valve, which isolates the dispenser from the manifold, when coupled to the dispenser. The first and second piston cylinders of each subsystem also alternatingly receive a solvent from the corresponding manifold and direct the solvent to a waste receptacle by a corresponding subsystem voltage blocking valve when the subsystem is not coupled to the dispenser. The solvent removes previously supplied coating material from the non-selected subsystem and readies the non-selected subsystem for supplying a next selected coating material to the dispenser.
