  • Patent number: 5554344
    Abstract: This device is a gas ionization device which can also be referred to as a corona discharge type of ozone generator. The design is tubular comprised of an inner and outer concentric metal electrode and ground plane with a glass dielectric tube disposed between them. Gas is passed between the dielectric and the ground plane for the purpose of producing concentrations of ozone. The electrode as well as the ground plane are designed to permit cooling of the ozone producing chamber. An electro-static field enhancing technique effectively produces a significant greater amount of ozone as a result.
