Abstract: A cell or apparatus for treating a fluid by electron emission as the fluid is passed through a space between a dielectric layer located on a surface of a first electrode and a second electrode and as the electrodes are operated by an attached, appropriate circuit to cause electron emission within the space can be constructed so as to improve the efficiency of the cell or apparatus and so as to promote the amount of time which the dielectric layer may be used without breakdown. In constructing a cell or apparatus for this purpose cooling jackets are provided for circulating cooling fluids in contact with the surfaces of these electrodes remote from one another. In accordance with the disclosure the pressures of the fluids used in the cooling jackets and the fluid passing through the space of the apparatus or cell are regulated so as to maintain the electrical characteristics of the cell or apparatus substantially constant. This improves the efficiency of the circuit used to power the cell.

Abstract: Improved efficiencies in the treatment of a fluid such as oxygen or an oxygen containing gas by electron emission so as to produce a product such as ozone may be achieved by regulating the manner in which energy is used within a fluid treatment cell and the circuit used to power such a cell. Such a cell normally consists of two electrodes separated from one another by a dielectric layer and an air gap. The apparatus used to power such a cell preferably includes a power supply, a timing generator, transistors for releasing power from the power supply to a transformer at periodic intervals, diodes for permitting power to be reconveyed from the transformer to the power supply, an inductance either built into or associated with the secondary of the transformer, this secondary being connected across the terminals of the cell. With this circuit energy is stored in the cell and in both of the inductances as power is supplied.
