Abstract
An improved apparatus for generating a negative charge effect in the environment, in which opposite charged spaced electrically conductive plates are dielectric material. A relatively high alternating voltage is applied between alternate spaced plates with sufficient dielectric strength and dielectric constant to withstand the generation of a cold glow discharge or plasma, and withstand the deposit of dirt on them, and withstand exposure to corrosion, humidity, high temperatures, corrosive gases and fumes. A process is disclosed for the separation of undesirable gases and particulates in polluted areas or airstreams. The present invention relates to the excitation, dissociation, and breakdown of gases and other pollutants.
