    Abstract: A electrostatic powder feeder includes a body having a cavity. The cavity is shaped and sized to hold a supply of powder particles and is defined by a cavity wall. A diverter is disposed in the cavity and positioned away from the cavity wall so as to create a powder flow space between the diverter and cavity wall. The feeder includes an electrode and a powder landing surface connected to a power supply. The electrode is positioned remotely from the powder landing surface at a distance at which it can act upon powder resting upon the powder landing surface. An aperture through which powder particles may fall is disposed in or proximate to the powder landing surface. An insulator is positioned between the electrode and the powder landing surface. The power supply produces an alternating electric potential that creates an alternating electric field between the electrode and powder landing surface that causes powder particles to oscillate and eventually fall through the aperture. In an alternative embodiment, the powder landing surface is on a diaphragm connected to the body and disposed below the powder flow space. The diaphragm is sized and shaped to hold a quantity of powder falling from the powder flow space. The diaphragm includes an aperture. A vibration actuator is affixed to the diaphragm, which provides a vibratory force to the powder particles.

    Abstract: A spray device includes a nozzle that forms a channel for supplying liquid to at least one opening for spraying the liquid outside the device, and, close to the opening, a first and a second electrode arranged in such a way as to inject electric charges into the liquid. The edge of the opening includes, on one side of the channel, at least one projecting end of the first electrode that projects into the channel and is to be brought into contact with the liquid, and on the other side of the channel, an electrically insulating nozzle body in which the second electrode is embedded adjacently to the first electrode, in such a way that the intensity of the electrostatic field in the or each projecting end is maximised.

    Abstract: A method of ionizing a liquid propellant is disclosed herein. The method includes the steps of applying an electrical charge to a showerhead, delivering a liquid propellant under pressure into a chamber defined within the showerhead, and emitting the liquid propellant under pressure through a plurality of micro-nozzles interspaced within the face of the showerhead to create a plurality of jets that collectively produce an electrospray having charged particles. An electric thruster that implements such a method is also disclosed herein. The thruster includes a showerhead having an inlet and a plurality of micro-nozzles, a reservoir for supplying propellant to the showerhead via the inlet, means for accelerating charged particles, and a power source connected to the showerhead and the accelerating means. The propellant is emitted under pressure from the micro-nozzles to produce an electrospray having charged particles. The charged particles are accelerated by the accelerating means to produce thrust.
