Abstract:
This manual gun (2) for applying a coating product comprises a high voltage unit (42), designed for electrostatically charge the coating product at a voltage/flow rate characteristic when it is supplied with electric power, and adjustment means (16), for selecting, from among several pre-adjusted voltage/current characteristics, the voltage/current characteristic according to which the product is electrostatically charged. This gun also comprises a control member (10), which is maneuverable between an inactive configuration, where it opposes the application of the coating product and wherein the high voltage unit (42) is not supplied with electric power, and an active configuration, wherein it does not oppose the application of the coating product and wherein the high voltage unit is supplied with electric power. The adjustment means (16) comprise control buttons, giving the possibility of manually adjusting the flow rate of coating product applied by the gun when the control member (10) is in an active configuration and of selecting the voltage/current characteristic when the control member is in an inactive configuration.
Abstract:
A system to apply mainly phytosanitary products that use the principle of electrostatic attraction. A high static charge is imprinted on the microdrops in the nozzle with high flows of water using a simple industrial design and very low probabilities of failure. The system is very stable and reliable. An active water provider capillary tube is optionally used in the nozzles (as opposed to a fixed one), which results in a more efficient use of the air to micronize drops. The nozzles can be fixed or dirigible nozzles. A chemical product doser system is optionally used with injection in the nozzle itself.
Abstract:
Devices, systems, and methods for charging fluids are disclosed. The charging of fluids improves the mixing of fluids in microfluidic systems. The charging is performed by producing an ion field (50) between an ionizing electrode (20) and an opposed ground electrode (30). A fluid-containing vessel (40) is positioned between the opposed electrodes and the ion field charges the fluid (41) in the vessel.

The device includes an atomization electrode (6), which generates electrostatically charged atomized water droplets to increase the hydrophilicity, a water supply member (8), which supplies water to the atomization electrode (6), and a voltage application member (9), which applies voltage to the water supplied to the atomization electrode (6).
Abstract:
The liquid is supplied to an emitter electrode which is provided at a tip of a liquid carrier, receives a high voltage, is electrical-charged, and discharged as a mist of charged minute water particles of nanometer order from the emitter electrode. The emitter electrode discharges the mist of the charged minute water particles of micron order at the same time by a pressure which is applied to the liquid which is supplied to the tip of the emitter electrode. An electrostatically atomizing device supplies liquid to an emitter electrode of a tip of a liquid carrier, applies the high voltage to the liquid, electrically-charges the liquid, and causes the emitter electrode to discharge a mist of charged minute water particles of nanometer order. In addition, the electrostatically atomizing device applies a pressure to the emitter electrode and causes the emitter electrode to discharge a mist of the charged minute water particles of micron order. The electrostatically atomizing device is able to humidify a space by the mist of the charged minute water particles of micron order as well as is able to decompose harmful substances in the space, is able to sterilize and deodorize the substances in the space by radicals which is included by the mist of the charged minute water particles of nanometer order.

An apparatus for dispersing fluent material comprises a body defining a plurality of orifices arranged around a central axis and a charge injection device arranged on the central axis.
Abstract:
An apparatus for dispersing a fluent material has an initial disperser for breaking a stream of fluent material into discontinuous parts. The apparatus has an electrode supply device that provides free electrons that impart a net charge on the discontinuous parts to disperse the discontinuous parts. A method is also disclosed in which electrons are directed at a flow of droplets of fluent material to disperse the fluent material.
Abstract:
An electrostatic atomizer is disclosed, which includes an electrode or other charge injection device and a source of liquid for passing a stream of liquid past the charge injection device to a variable orifice. The variable orifice is defined between at least two elements, which are movable with respect to each other. A compact stove incorporating the atomizer includes a support for supporting articles to be heated by the burning of atomized fuel. The variable orifice may be used in the stove to control the flow, and therefore thermal output, of the stove.
