Abstract
Abstract A clean water system that has a noval air system and a novel water system in which the dry air to the case of the ozone generator as well as to the ozone generator and has a primary drier, a sensor and reserve drier such that the reserve drier provides dry air after the primary drier has become too wet and the water system includes a pair of concentrically mounted tanks with an overflow such that water can be circulated in a closed loop through the ozone injector and inner tank to purify the water.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
111 words
An air drying system for an ozone generator which is mounted in an air sealed case comprising, a predrier which receives ambient air, said air sealed case of said ozone generator connected to receive output air from said predrier, a primary drier connected to receive output air from said case, a sensor connected to the output air of said primary drier, a reserve drier connected to receive the output air of said primary drier and to supply input air to said ozone generator which converts a portion thereof to ozone and an ozone injector connected to said ozone generator to receive said ozone and to inject it into a water supply.
Claim 2
Dependent Claim
111 words
An air drying system for an ozone generator which is mounted in an air sealed case comprising, a predrier which receives ambient air, said air sealed case of said ozone generator connected to receive output air from said predrier, a primary drier connected to receive output air from said case, a sensor connected to the output air of said primary drier, a reserve drier connected to receive the output air of said primary drier and to supply input air to said ozone generator which converts a portion thereof to ozone and an ozone injector connected to said ozone generator to receive said ozone and to inject it into a water supply.
Claim 3
Dependent Claim
33 words
An air drying system according to claim 1 including an indicator connected to said sensor to indicate the moisture content in said air which is supplied to said sensor by said primary drier.
Claim 4
Dependent Claim
121 words
A water purifying system comprising, an ozone generator to which dry air is supplied, an ozone injector connected to said ozone generator, water cooling passages formed in said ozone generator to which an input first conduit and an output second conduit are connected, said output second conduit connected to said ozone injector and ozone injected into water passing therethrough, a third conduit connected to said ozone injector, a tank connected to said third conduit and receiving water therefrom which enters said tank near the bottom thereof, a fourth conduit extending from adjacent the top of said tank to said input first conduit of said ozone generator, and a sixth conduit connected to said tank from which purified water can be removed.
Claim 5
Dependent Claim
121 words
A water purifying system comprising, an ozone generator to which dry air is supplied, an ozone injector connected to said ozone generator, water cooling passages formed in said ozone generator to which an input first conduit and an output second conduit are connected, said output second conduit connected to said ozone injector and ozone injected into water passing therethrough, a third conduit connected to said ozone injector, a tank connected to said third conduit and receiving water therefrom which enters said tank near the bottom thereof, a fourth conduit extending from adjacent the top of said tank to said input first conduit of said ozone generator, and a sixth conduit connected to said tank from which purified water can be removed.
Claim 6
Dependent Claim
31 words
A water purifying system according to claim 3 including a seventh conduit with its output connected to said third conduit, and unpurified water connected to the input of said seventh conduit.
Claim 7
Dependent Claim
67 words
A water purifying system according to claim 4 wherein said tank has two separate compartments with a first compartment in which the outlet of said third conduit and the inlet of said fourth conduit are mounted, and a second compartment which is fluidly connected to said first compartment by an output near the top of said first compartment and said sixth conduit connected to said second compartment.
Claim 8
Dependent Claim
55 words
A water purifying system according to claim 5 including a first valve connected in said seventh conduit, an upper water level sensing means mounted in an upper portion of said second compartment and connected to control said first valve to open it when the water level in said second compartment falls below a preset level.
Claim 9
Dependent Claim
60 words
A water purifying system according to claim 6 including a lower water level sensing means mounted in a lower portion of said second compartment and second valve mounted in said sixth conduit and controlled by said lower water level sensing means so that it is turned off when the water level in said second compartment falls below a predetermined level.
Claim 10
Dependent Claim
17 words
A water purifying system according to claim 6 wherein said first and second compartments are concentrically mounted.
Claim 11
Dependent Claim
18 words
A water purifying system according to claim 8 wherein said first compartment is mounted inside said second compartment.
