Abstract: An ozone generator plate has a first electrode with a pattern on a dielectric plate and a second electrode on the opposite side of the plate that is larger than the first electrode so that corona is developed for a finite distance beyond the edges of the first electrode on the surface of the dielectric plate. The dielectric plate is preferably a ceramic and the electrodes are coated on the ceramic with nickel chromium alloy overcoated with at least palladium and a lead tin alloy.

Abstract: An ozone generator is provided, with a resonant power circuit to energize the corona plates. The circuit includes a pair of transistors where the primary winding of the transformer acts as the collector load on each of the transistors. Additionally, two other transistors are provided for safety purposes to short the base signal of the power transistors if the power supply to the ozone generating plates gets too high. The circuit is resonant thereby requiring low power consumption. The resonant circuit takes full advantage of the characteristics of the transformer to quickly and efficiently energize the plates for the generation of corona for the purpose of creating ozone.

Abstract: An air purifying apparatus that has an ozone generator which generates plasma field in the ultraviolet region. It utilizes a pair of electrodes in the form of plates that are separated by an insulator. The plates are connected to a high-voltage transformer through diodes in such a way that only a negative and less positive charges appear on the plates. The generator is provided with a self-cleaning apparatus in which the circulating air fan that is provided for normally forcing air through the electrostatic plates may be turned off for a period of time and the ozone generated by the plates at that point in time will tend to combine with the contaminates and oxidize the same.
