Abstract
Abstract Drinking water under pressure is fed automatically, when necessary, through a float valve into a sealed contact tank, which has an air space in its upper end. An electrically controlled ozone generator has its output connected to a diffuser that is mounted in the lower end of the tank; and a pressure regulator is mounted in the top of the tank to vent its air space when the pressure therein rises above, for example, five pounds per square inch. The tank itself may be surrounded by a cooling coil, so as to function both as a contact and cooling tank, or its output may be connected to a second tank surrounded by a cooling coil. The ozone generator may be periodically energized by a timer, or by a thermostat which is responsive to the temperature of the water in the cooling tank.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
179 words
A pressurized drinking water purifier and cooler, comprising a sealed tank, first valve means connecting said tank to a supply of water under pressure, and operative automatically to maintain the water in said tank at a predetermined level spaced beneath the upper end of said tank, pressure regulating means on said tank connected to the space in said tank above the level of the water therein, and operative to vent said space to atmosphere, when the pressure in said space exceeds a predetermined value, a diffuser mounted in said tank adjacent the lower end thereof, Means energizable to supply ozone gas to said diffuser at a pressure greater than said predetermined value, whereby said gas is bubbled upwardly through the water in said tank by said diffuser to purify said water, second valve means operable to effect withdrawal of water from said tank, means interposed between said tank and said second valve means for cooling the purified water, and control means operative automatically and periodically to energize said supply means to supply ozone gas under pressure to said diffuser.
Claim 2
Dependent Claim
179 words
A pressurized drinking water purifier and cooler, comprising a sealed tank, first valve means connecting said tank to a supply of water under pressure, and operative automatically to maintain the water in said tank at a predetermined level spaced beneath the upper end of said tank, pressure regulating means on said tank connected to the space in said tank above the level of the water therein, and operative to vent said space to atmosphere, when the pressure in said space exceeds a predetermined value, a diffuser mounted in said tank adjacent the lower end thereof, Means energizable to supply ozone gas to said diffuser at a pressure greater than said predetermined value, whereby said gas is bubbled upwardly through the water in said tank by said diffuser to purify said water, second valve means operable to effect withdrawal of water from said tank, means interposed between said tank and said second valve means for cooling the purified water, and control means operative automatically and periodically to energize said supply means to supply ozone gas under pressure to said diffuser.
Claim 3
Dependent Claim
64 words
A pressurized drinking water purifier and cooler as defined in claim 1, wherein said cooling means comprises a second tank connected to the first-named tank to receive water therefrom upon operation of said second valve means, and a refrigerating coil surrounding said second tank and operatively connected to a refrigeration unit to chill the water in said second tank upon energization of said unit.
Claim 4
Dependent Claim
53 words
A pressurized drinking water purifier and cooler as defined in claim 2, wherein said second valve means comprises a manually-operable valve connected to an outlet on said second tank and operable to allow the discharge of water from said second tank under the pressure maintained in said first tank by said regulating means.
Claim 5
Dependent Claim
69 words
A pressurized drinking water purifier and cooler as defined in claim 1, wherein said cooling means comprises a refrigerating coil surrounding said tank and operatively connected to a refrigeration unit to chill the water in said tank to a predetermined temperature upon energization of said unit, and said second valve means comprises a manually-operable valve connected to an outlet in said tank and operable selectively to withdraw water therefrom.
Claim 6
Dependent Claim
52 words
A pressurized drinking water purifier and cooler as defined in claim 4, wherein said control means includes means responsive to the temperature of the water in said tank simultaneously to energize said ozone supply means and said refrigeration unit, when the temperature of the water in said tank exceeds said predetermined temperature.
Claim 7
Dependent Claim
60 words
A pressurized drinking water purifier and cooler as defined in claim 5, wherein said temperature responsive means includes means for deenergizing said refrigeration unit when the temperature of the water in said tank falls below said predetermined temperature, and means for maintaining said ozone supply means energized for a predetermined period of time after the deenergization of said refrigeration unit.
Claim 8
Dependent Claim
197 words
A pressurized drinking water purifier and cooler, comprising a sealed tank, first valve means connecting said tank to a supply of water under pressure, and operative automatically to maintain the water in said tank at a predetermined level spaced beneath the upper end of said tank, a pressure regulator connected to the top of said tank to vent the space therein above the level of the water in said tank, when the pressure in said space exceeds a predetermined value, a manually operable valve connected to an outlet in said tank adjacent the lower end thereof, and operable to draw water from said tank at said predetermined pressure, an ozone generator disposed exteriorly of said tank, a diffuser mounted in said tank adjacent said lower end thereof and connected to the output of said generator to receive ozone gas therefrom, a refrigeration unit mounted exteriorly of said tank, a refrigerating coil surrounding said tank and connected to said unit to cool the water in said tank to a predetermined temperature upon operation of said unit, and electrical control means connected to said generator and said unit and operative periodically to energize both said generator and refrigeration unit.
Claim 9
Dependent Claim
197 words
A pressurized drinking water purifier and cooler, comprising a sealed tank, first valve means connecting said tank to a supply of water under pressure, and operative automatically to maintain the water in said tank at a predetermined level spaced beneath the upper end of said tank, a pressure regulator connected to the top of said tank to vent the space therein above the level of the water in said tank, when the pressure in said space exceeds a predetermined value, a manually operable valve connected to an outlet in said tank adjacent the lower end thereof, and operable to draw water from said tank at said predetermined pressure, an ozone generator disposed exteriorly of said tank, a diffuser mounted in said tank adjacent said lower end thereof and connected to the output of said generator to receive ozone gas therefrom, a refrigeration unit mounted exteriorly of said tank, a refrigerating coil surrounding said tank and connected to said unit to cool the water in said tank to a predetermined temperature upon operation of said unit, and electrical control means connected to said generator and said unit and operative periodically to energize both said generator and refrigeration unit.
Claim 10
Dependent Claim
43 words
A pressurized drinking water purifier and cooler as defined in claim 7, wherein said control means includes means responsive to predetermined changes in the temperature of the water in said tank momentarily to energize both said generator and unit at the same time.
Claim 11
Dependent Claim
36 words
A pressurized drinking water purifier and cooler as defined in claim 8, wherein the last-named means includes means for maintaining said generator energized for a predetermined period of time following the deenergization of said refrigeration unit.
