Abstract
An atomizing apparatus comprises an electrode, an orifice through which coating material to be atomized is discharged, and a power supply for maintaining across the electrode and an article to be coated by coating material dispensed from the apparatus a potential for transferring electrical charge to the material to be atomized to cause the material to be attracted toward the article. The apparatus has a first surface providing a locus for electrical discharge when the potential is maintained on the electrode. At least one first resistance has first and second terminals adjacent the first surface and the electrode, tending to localize the discharge at the first surface to the first terminal.
