Abstract:
A seawater desalination apparatus includes a spray (1), a gas supplier (9), an atomizing electrode (2), a high voltage power supply (3), a mist classifier (4), and a mist collector (5). The spray includes apertures for producing a seawater mist. The supplier supplies gas for carrying the mist from the spray. The electrode electrostatically produces fine droplets from the mist from the spray. The power supply is connected to the electrode and the spray, and applies high voltage between the electrode and the spray for the production of fine droplets from the mist from the atomizer. The classifier separates the fine droplets in the mist from the electrode. The collector collects the mist discharged from the classifier thereby producing fresh water.
Abstract:
Systems and methods for rapidly atomizing and dispensing electrostatically atomized insecticides and similar low electrical conductivity active materials without the use of VOCs. The active materials are dispensed via insertion of a disposable cartridge in a dispensing apparatus. The dispensing apparatus is hand actuated and the exhausted cartridge is minimized to the size of a wad of chewing gum and it is doubly sealed to prevent any residual active material from leaking into the environment. Spray flow and configuration may be user selectable.

The variable orifice may be used in the stove to control the flow, and therefore thermal output, of the stove.
Abstract:
A spray gun for airless atomization and electrostatic deposition of a coating material upon a substrate, including a gun nozzle tip element serving to prevent arcing from the gun nozzle tip to an adjacent electrical ground. As disclosed, the airless spray gun includes a metallic nozzle tip from which atomized liquid coating material is emitted, and the thus-emitted coating material is charged by an electrode mounted on the nozzle which is electrically isolated from the metallic tip. During use of the spray gun, the metallic tip becomes charged via electrical charge conduction through the emitted atomized coating material. To prevent arcing from the charged tip to an electrical ground, a pair of resistive threads are secured in bores in the spray gun nozzle, each having a first end electrically connected to the conductive tip and a second end extending slightly beyond the nozzle. If an electrical ground approaches the charged conductive tip, the resistive threads are positioned such that electrical energy on the tip is coupled to the electrical ground through one or both of the resistive threads in the form of a low energy corona discharge.

An airless electrostatic spray gun for atomizing and electrostatically depositing liquid coating materials onto substrates. The gun is characterized by a low capacitance which enables the electrode of the gun to be shorted to a grounded object without the resulting spark having sufficient energy content to ignite the surrounding atmosphere.
