Abstract: An electrostatic particle spray gun having, in one preferred embodiment, a conical deflector of insulative material mounted in the nozzle in the particle path for forming a conical particle spray pattern. A resistive sheet connected to a high voltage electrostatic supply is sandwiched between the forward and rearward ends of the deflector, leaving only the perimeter of the sheet exposed at the peripheral region of the conical deflector. The perimeter of the resistive sheet functions as a multi-point circular electrode for charging the particles such that improved coating transfer efficiencies are achieved. Also, because of the resistive nature of the resistive sheet, the sheet constitutes a resistor in the electrical current path between the center of the sheet where it connects to a high voltage terminal and the circular periphery of the sheet which serves as the multiple point charging electrode, thereby minimizing unsafe electrical discharges should the electrode inadvertently approach a grounded object.

Abstract: An improved powder pump for pumping air entrained solid particulate powder material comprising a pneumatic conveyor line within which there is located a low pressure venturi pumping chamber. This venturi pumping chamber is intersected by a powder supply passage through which powder is drawn via a siphon tube into the conveyor line from a fluidized bed source of powder material. Over the inlet end of the siphon tube there is a cone shaped deflector plate which functions to reduce the inflow of air bubble created powder voids and consequent uneven flow of powder from the pump.
