Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
160 words
An apparatus for purifying water by supplying low frequency square waves and higher frequency square waves of mutually opposed polarity and ozone to the water comprising: electrodes; means for supplying water between said electrodes; an AC or a DC power source with its respective converter; means for supplying power to control means; said control means comprising a frequency divider, two coupled operational amplifiers, two pairs of transistors working in a push-pull mode, two pairs of coupled power switching transistors and of about 2 kHz oscillators of square waves connected in such a manner as to produce and simultaneously apply square wave impulses of a low frequency and a higher frequency to the electrodes; means to produce spark; means to connect said means to produce spark to said impulses in such a manner as to supply a spark to a stream of air to produce ozone; and means to deliver the stream of air and the produced ozone to the water.
Claim 2
Independent Claim
160 words
An apparatus for purifying water by supplying low frequency square waves and higher frequency square waves of mutually opposed polarity and ozone to the water comprising: electrodes; means for supplying water between said electrodes; an AC or a DC power source with its respective converter; means for supplying power to control means; said control means comprising a frequency divider, two coupled operational amplifiers, two pairs of transistors working in a push-pull mode, two pairs of coupled power switching transistors and of about 2 kHz oscillators of square waves connected in such a manner as to produce and simultaneously apply square wave impulses of a low frequency and a higher frequency to the electrodes; means to produce spark; means to connect said means to produce spark to said impulses in such a manner as to supply a spark to a stream of air to produce ozone; and means to deliver the stream of air and the produced ozone to the water.
Claim 3
Independent Claim
156 words
A method of purifying water comprising: treating the water with low frequency square waves and simultaneously higher frequency square waves of mutually opposed polarity and ozone produced from an apparatus comprising electrodes; means for supplying water between said electrodes; an AC or a DC power source with its respective converter; means for supplying power to control means; said control means comprising a frequency divider, two coupled operational amplifiers, two pairs of coupled power switching transistors and of about 2 kHz oscillators of square waves connected in such a manner as to produce and simultaneously apply square wave impulses of a low frequency and a higher frequency to the electrodes; means to produce spark; means to connect said means to produce spark to said impulses in such a manner as to supply a spark to a stream of air to produce ozone; and means to deliver the stream of air and the produced ozone to the water.
