Abstract

Abstract A motorless carbonator with a mixing chamber having associated therewith a water supply system, a gas supply system, a vent system, a liquid level sensing device, and a dispensing device. The sensing device is adapted to sense a minimum and a maximum desired fluid level in the chamber and to actuate valves controlling the water supply, gas supply and vent in accordance therewith. The water supply valve has a time delay device to allow venting of the chamber prior to water inflow and the dispensing device is adapted to override actuation of the valves by the sensing device while the dispensing device is in operation.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 151 words
A device for carbonating liquids comprising: a pressurizable mixing chamber; a gas supply system; a fluid supply system; a vent system; a dispensing system; said systems communicating to the interior of said mixing chamber; first valve means associated with the said gas supply system effective to control flow of gas to the said chamber; second valve means associated with the fluid supply system adapted to control flow of fluid to the chamber; third valve means associated with the vent system adapted to control venting of the said chamber; a control system; said control system adapted to sense maximum and minimum desired fluid levels in the said mixing chamber; said control system adapted to operate the said first, second and third valve means in dependent response to fluid level in the said chamber; and means for delaying actuation of the said second valve means until after actuation of the third valve means.
Claim 2
Independent Claim 151 words
A device for carbonating liquids comprising: a pressurizable mixing chamber; a gas supply system; a fluid supply system; a vent system; a dispensing system; said systems communicating to the interior of said mixing chamber; first valve means associated with the said gas supply system effective to control flow of gas to the said chamber; second valve means associated with the fluid supply system adapted to control flow of fluid to the chamber; third valve means associated with the vent system adapted to control venting of the said chamber; a control system; said control system adapted to sense maximum and minimum desired fluid levels in the said mixing chamber; said control system adapted to operate the said first, second and third valve means in dependent response to fluid level in the said chamber; and means for delaying actuation of the said second valve means until after actuation of the third valve means.
Claim 3
Dependent Claim 40 words
The device of claim 1 wherein the said dispensing system includes a second control system effective to override the first control system to prevent actuation of the said first, second, and third valve means during actuation of the dispensing system.
Claim 4
Independent Claim 198 words
The method of carbonating a fluid in a pressurizable container comprising the steps of: supplying a fluid to the chamber with the chamber at a first pressure; sensing the fluid level in the chamber; simultaneously terminating supply of fluid to the chamber; sealing the chamber, and initiating supply of pressurized gas to the chamber in dependent response to the fluid level in the chamber; continuing to supply pressurized gas to the chamber until a second pressure level is obtained in the chamber; thereafter ceasing supply of gas to the chamber; dissolving some of said supplied gas in the fluid in the chamber to create a soda; withdrawing some of said soda from the chamber; selectively supplying further pressurized gas to the said chamber to retain the said chamber at the said second pressure level; sensing fluid level in the said chamber during and after withdrawal of said soda; simultaneously terminating supply of gas to the said chamber and unsealing the said chamber to return the said chamber to the said first pressure level in dependent response to the fluid level in the said chamber; and thereafter supplying fluid to the said chamber at the said first pressure level.
Claim 5
Independent Claim 198 words
The method of carbonating a fluid in a pressurizable container comprising the steps of: supplying a fluid to the chamber with the chamber at a first pressure; sensing the fluid level in the chamber; simultaneously terminating supply of fluid to the chamber; sealing the chamber, and initiating supply of pressurized gas to the chamber in dependent response to the fluid level in the chamber; continuing to supply pressurized gas to the chamber until a second pressure level is obtained in the chamber; thereafter ceasing supply of gas to the chamber; dissolving some of said supplied gas in the fluid in the chamber to create a soda; withdrawing some of said soda from the chamber; selectively supplying further pressurized gas to the said chamber to retain the said chamber at the said second pressure level; sensing fluid level in the said chamber during and after withdrawal of said soda; simultaneously terminating supply of gas to the said chamber and unsealing the said chamber to return the said chamber to the said first pressure level in dependent response to the fluid level in the said chamber; and thereafter supplying fluid to the said chamber at the said first pressure level.
Claim 6
Dependent Claim 87 words
In a device for carbonating fluids in a pressurizable chamber having gas and fluid supply systems associated therewith and positive action means for controlling flow from the supply systems to the chamber, the flow being from only one of the supply systems at a time, the improvement of actuatable means for venting the chamber while the flow from the gas supply system is stopped and means for delaying flow of fluid to the chamber until after the means for venting has been actuated to vent the chamber.
Claim 7
Dependent Claim 87 words
In a device for carbonating fluids in a pressurizable chamber having gas and fluid supply systems associated therewith and positive action means for controlling flow from the supply systems to the chamber, the flow being from only one of the supply systems at a time, the improvement of actuatable means for venting the chamber while the flow from the gas supply system is stopped and means for delaying flow of fluid to the chamber until after the means for venting has been actuated to vent the chamber.
