  • Patent number: 4561037
    Abstract: Portable electrostatic spraying apparatus having a low stored energy wherein the capacitor of the high voltage circuit is formed by the capacitance between a lead connecting the high voltage generator output to the spray nozzle and a lead connected to the other side of the generator output.
    Type: Grant

  • Patent number: 4549243
    Abstract: Electrostatic spraying apparatus e.g. for graphic work, having a hand or finger held body carrying a nozzle to which the atomizing potential is applied from a high voltage generator. The nozzle is of the non-drip type, e.g. a capillary bore or a felt- or fibre-tip so that no liquid is dispensed therefrom in the absence of the atomizing potential. The nozzle and liquid reservoir may be a cartridge, e.g. a felt-tip graphic marker. The generator may be within the body so as to provide a self-contained unit which can be "earthed" via the user's hand.
