Abstract
Abstract The ozonization installation comprises a group of n ozonizers supplied with energy by a common source in a successive alternating voltage wave train mode, the application of the wave trains being controlled by a control device. The latter produces initiating signals which selectively enable the passage of the electric energy in the form of wave trains coming from the common source to the ozonizer. The installation comprises a servo system chain comprising devices for controlling the duration of the initiating signals by means of a set signal, having regard to the total ozonization produced by the n ozonizers. This duration corresponds to that of each successive wave train. Synchronization devices are provided for connecting the common energy source to solely one ozonizer at a time.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
147 words
In a method for supplying electric power to an ozone producing element comprising at least two conductive electrodes disposed in facing relation to each other and between which electrodes a gas to be ozonized flows, comprising the step of applying to said electrodes sequential bursts of electrical energy with a voltage whose amplitude value is capable of producing electronic discharges between electrodes with each burst comprising a wave train of alternating voltage, the bursts being separated from each other in time by time periods during which the volume of gas treated by a first burst will be at least partly evacuated from the space between the electrodes prior to the application of the second burst, and the step of providing to said electrodes an electrical condition during said time periods between bursts to cause gas ions resulting from the said first burst to remain between said electrodes.
Claim 2
Dependent Claim
147 words
