Abstract: A powder spray gun includes a rotary distributor which is capable of operating at slower speeds than liquid spray gun to reduce the problem of powder fusing, increases bearing life, reduce wear on moving parts. The powder spray gun has a powder flow path which extends through a gun body to a powder outlet. The rotatable powder distributor is located at the powder outlet. A drive mechanism in the form of a pneumatic motor is located within the housing and connected to the distributor the rotate the distributor. A spindle, which is mounted for rotation within the body, has a passageway therethrough which forms a part of the powder flow path. The distributor communicates with the passageway and is attached for rotation with the spindle. The powder thus enters the passageway in the rotating spindle before it passes into the rotating distributor. A chamber is formed within the body around the spindle, and the chamber is connected to an air supply to pressurize the chamber. A nonrotating flow tube through which powder flows into the passageway in the spindle, with a gap being formed between the nonrotating flow tube and the rotatable spindle. The gap communicates with the chamber whereby pressurized air from the chamber escapes through the gap to provide a rotary seal between the tube and the spindle. A sealing member may be used to prevent back flow of air through the gap.

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 rotary atomizer for spray coating objects includes an onboard color changer valve manifold as well as an optional onboard fluid pressure regulator. The manifold facilitates rapid and efficient color changing while reducing coating material wastage and solvent usage. The invention also contemplates mounting the color changer repositionally along an axis which preferably coincides with the rotary axis of the atomizer. This facilitates installation and removal of the regulator and permits the coating material flow path between the discharge port of the color changer and the atomizing head to be kept short and straight which improves flow control and facilitates thorough flushing of the flow path with solvent. Other improvements including a particular color changer manifold and atomizer head structure are also disclosed.

Abstract: An improved rotary paint atomizing device in the form of a bell and a cover plate which is releasably attached to the front center of the bell. Paint fed along the axis of the device onto a conical projection on the back surface of the cover plate accelerates and flows outward in a radial direction. The cover plate surface is curved so that as the paint flows outwardly, it also flows first forward and then back until it reaches radial slots formed in a peripheral rim on the cover plate where the cover plate contacts an interior bell surface. Paint discharges from the slots onto a conical interior bell surface and flows in wide, closely spaced ribbons which merge into a uniform, continuous thin sheet before it is discharged from the bell edge. As the paint discharges from the bell edge, the sheet produces extremely fine uniform ligaments which break up to produce fine, uniform small paint particles.

Abstract: Spraying unit for spray coating articles with powdered or liquid material contains a spray head fastened to a front end of a tubular inner and axially extending support and an outer protective tube disposed concentrically about the inner support. The inner support and the outer protective tube are electrically insulative. One or more high-voltage generators are spacedly disposed about the inner support, axially rearward of the spray head, and within an elevated pressure chamber defined between the protective tube and the inner support. The arrangement is such that it produces a constant outwardly bound flow of gas from the elevated pressure chamber which flow prevents soilage of the internal parts by coating material. Structurally, the spraying unit is compact and slim and its parts are so interconnected that electrically conductive coating material cannot form conductive bridges that may bridge the high voltage at the electrostatically charging spray head or the high-voltage generators to ground or other lower potential regions.

Abstract: Electrostatic spraying of liquid compositions is carried out by supplying the liquid to a spray orifice, preferably of capillary dimensions, having a charged surface which is electrically conducting or semi-conducting and which is adjacent a field intensifying electrode, the arrangement being such that the liquid is drawn out primarily by electrostatic forces, atomized into electrically charged particles without substantial corona discharge and projected past the field intensifying electrode. The spraying process and apparatus has particular utility in the spraying of liquid pesticide compositions at ultra-low volume, in that the droplets are of uniform size and are electrostatically attracted to the plants so as to wrap around the leaves of the planets and coat both the upper and lower surfaces of the leaves.
