Abstract: An electrostatic sprayer for spraying a liquid includes a nozzle formed from a a nozzle body that has an inlet for receiving a liquid and a liquid tip having an outlet for ejection of the liquid to form a liquid spray. The nozzle also includes an electrode disposed around the outlet of the liquid tip for charging the liquid and a dielectric shroud disposed around at least a portion of the liquid tip to prevent leakage currents from reducing a potential of the electric field between the liquid and the electrode, which would otherwise reduce the effectiveness of the sprayer. A conductor that couples the electrode to a power supply may pass through a hole extending through the shroud. The shroud may include one or more vents to permit air and liquid to pass through the dielectric shroud to reduce accumulation of liquid.

Abstract: A coating apparatus produces a spray of charged droplets and controls the spray angle of travel of the spray toward the object to be coated. Electrically charging droplets minimizes the amount of coating material required to uniformly coat a surface as compared to conventional web coating techniques such as blade coating. An inductive ring guides the spray charged droplets as they exit the nozzle of a spray device. The electrostatic repulsion between the charged droplets insures that a uniform coating of liquid formulation can be applied to a web surface.

Abstract: An apparatus for spraying and inducing an electrostatic charge upon a liquid in excess of 0.8 millicoloumb/kilogram is connectable to a boom fitted to a vehicle, such as an aircraft, having a dc power supply. The apparatus comprises a nozzle constructed from a substantially non-conductive material and includes a spray tip designed to provide a hollow conical spray pattern. A support member extends from the nozzle and supports a charging electrode for inducing an electrostatic charge upon the liquid sprayed through the nozzle. The charging electrode attaches to the support member and is electrically connectable to the dc power supply. The charging electrode includes a cylindrical portion and a plurality of corona discharge members extending inwardly from a distal end of the cylindrical portion adjacent to the spray tip. The charging electrode is positioned to permit the hollow conical spray pattern to pass unhindered therethrough.

Abstract: A paint cartridge (21) is formed by a baggy tank (23) and a tank accommodating cylindrical body (22) formed of a transparent hollow tubular body. The baggy tank (23) is provided in the tank accommodating cylindrical body (22) as a dual structure formed by an inner bag (28) and an outer bag (29). A paint chamber (30) inside the inner bag (28) is connected to a feed tube (14), and an extruding liquid flows into and out of an extruding liquid chamber (32) between the outer bag (29) and the tank accommodating cylindrical body (22). A detector (33) which is visually observable from outside the tank accommodating cylindrical body (22) is provided on the inner bag (28) and the outer bag (29) of the baggy tank (23). As this detector (33), a material is used whose shape, pattern, or hue changes due to contact with the paint which leaks when the inner bag (28) has broken or the extruding liquid which leaks when the outer bag (29) has broken. In consequence, it is possible to detect the breakage of the inner bag (28) and the outer bag (29) by visually observing a change in the detector (33) from the outside.

Abstract: A diffuser comprises a conduit having a cross-sectional area that increases in a direction fluid flow. In one embodiment, the diffuser is used to reduce the incidence and severity of flow fluctuations that occur in an electrostatic deposition apparatus. In some embodiments, the diffuser includes one or more flow control features. A first flow-control feature comprises one or more appropriately-shaped annular slits through which fluid having a greater momentum than a primary fluid moving through the diffuser is injected into the “boundary layer” near the wall of the diffuser. A second flow control feature comprises one or more annular slits or, alternatively, slots or holes that are disposed at appropriate locations around the circumference of the diffuser through which a portion of fluid flowing in the boundary layer is removed. Boundary-layer flow removal is effected, in one embodiment, by creating a pressure differential across such annular slit or slots. Among other benefits, such flow control features reduce any tendencies for flow separation of the primary fluid in the diffuser.

Abstract: An atomizer has a chamber holding a liquid containing particles of a desired material. Aerosol particles are formed by using an aspirating nozzle or ultrasonic vibrator and the aerosol particles are carried in a gas flow. The aerosol particles are treated by increasing the charge on the aerosol particles by contact with a high voltage electrode and the aerosol particles are passed through inertial separator stages to remove large aerosol particles from the flow so they are not discharged from the atomizer.

Abstract: Air atomizing induction charging spray nozzles suited for use with conductive liquids, solutions, suspensions or emulsions. These systems feature a high level of the spray charging at low induction--electrode voltage and current. Primary benefits include consistent, reliable operation in harsh agricultural and industrial environments with a wide range of spray formulations, especially those having relatively high concentrations of abrasive and conductive materials. Internal and external surfaces are configured to minimize potential differences between electrode and ground. Such nozzles may employ external cavities, field concentrators, hoods and other structures and arrangements to affect aerodynamic flow of gases within the vicinity of the nozzles and electrostatic and electrodynamics effects such as those caused by electrical fields within the vicinity of the nozzles.
