Corona generator apparatus
First Claim
1. A corona generating device for producing ozone comprising a pair of parallel, spaced-apart electrodes connected to a voltage source Vo, a layer of thin hard dielectric material positioned between said electrodes, an air gap Ta of uniform width between said layer and the other of said electrodes, said layer having a thickness Td and a dielectric constant ε
- , said electrodes being spaced apart such that the following equation is satisfied;
##EQU11## where Ta -- air gap in milsVo -- applied peak voltage in voltsTd -- dielectric thickness in milsε
-- dielectric constant.

Abstract
In a corona generator preferably for generating ozone and employing a plurality of corona generating cells each comprising a pair of parallel spaced-apart electrodes and preferably having a fired-on coating of porcelain enamel and connected to a voltage source Vo and having an air gap Ta between said electrodes (between the porcelain enamel coating of the electrodes), said electrodes being spaced apart such that the following equation is substantially satisfied; ##EQU1## WHERE Ta -- air gap in mils
Vo -- applied peak voltage in volts
Td -- dielectric thickness in mils
ε -- dielectric constant
