Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 290 words
A control system of an ozonizer system comprising a plurality of ozone utilization devices; a plurality of ozonizer modules; an ozone distributor connected between the ozone utilization devices and the ozonizer modules for distributing ozone generated by said ozonizer modules among said ozone utilization devices; a raw material gas distributor for supplying raw material gas to said plurality of ozonizer modules; a source of variable voltage for supplying variable operating voltage to respective onozizer modules; a plurality of sensors which sense the operating conditions of respective ozone utilization devices; means responsive to the outputs of said sensors for producing a signal representing the quantity of ozone demanded by said ozone utilization devices; a central operation processing unit of an electronic computer, said central operation processing unit including a first memory device; a primary memory device controlled by said central operation processing unit and connected to receive the output signal of said means producing a signal representing ozone demand; an operation unit controlled by said central operation processing unit for operating on the data stored in said first memory device and said primary memory device; a power control panel connected to receive the output of said operation unit and controlled by said central operation processing unit for generating control signals for controlling the distribution of ozone among said ozone utilization devices, the voltage generated by said source of variable voltage, and the distribution of the raw material gas among said ozonizer modules; and a running condition setter including means for manually selecting the ozone modules and determining a total ozone quantity demanded by said ozone utilization devices which is applied to said primary memory device, and a clock pulse generator for supplying a clock pulse to said central operation processing unit.
Claim 2
Dependent Claim 290 words
A control system of an ozonizer system comprising a plurality of ozone utilization devices; a plurality of ozonizer modules; an ozone distributor connected between the ozone utilization devices and the ozonizer modules for distributing ozone generated by said ozonizer modules among said ozone utilization devices; a raw material gas distributor for supplying raw material gas to said plurality of ozonizer modules; a source of variable voltage for supplying variable operating voltage to respective onozizer modules; a plurality of sensors which sense the operating conditions of respective ozone utilization devices; means responsive to the outputs of said sensors for producing a signal representing the quantity of ozone demanded by said ozone utilization devices; a central operation processing unit of an electronic computer, said central operation processing unit including a first memory device; a primary memory device controlled by said central operation processing unit and connected to receive the output signal of said means producing a signal representing ozone demand; an operation unit controlled by said central operation processing unit for operating on the data stored in said first memory device and said primary memory device; a power control panel connected to receive the output of said operation unit and controlled by said central operation processing unit for generating control signals for controlling the distribution of ozone among said ozone utilization devices, the voltage generated by said source of variable voltage, and the distribution of the raw material gas among said ozonizer modules; and a running condition setter including means for manually selecting the ozone modules and determining a total ozone quantity demanded by said ozone utilization devices which is applied to said primary memory device, and a clock pulse generator for supplying a clock pulse to said central operation processing unit.
