Abstract: An apparatus for the carbonation of liquids, such as water, comprises a liquid storage tank coupled to a carbonizer having a carbonated liquid holding tank which presents a carbon dioxide atmosphere to liquid introduced therein. The liquid introduced into the holding tank blends with the carbon dioxide atmosphere, and is held in the tank for withdrawal upon demand. The liquid storage tank maintains a liquid therein at ambient pressure, and has a draw tube for liquid removal positioned proximate the bottom wall of the tank. The tank has a channel system in the tank bottom to allow liquid to collect therein to maximize the amount of liquid which may be withdrawn. Liquid level switches sense the level of liquid within the channel system and are coupled to the carbonizer to prevent its operation when insufficient liquid is present in the storage tank.

Abstract: Apparatus is provided for automatically carbonating a liquid. A pressure vessel receives carbonating gas at a pressure P.sub.1 via a first input, and a supply of liquid at a pressure P.sub.2 via a second input. P.sub.2 is greater than P.sub.1. The flow of liquid into the pressure vessel is restricted, to enable carbonating gas to enter the vessel and substantially reach the pressure P.sub.1 therewithin before liquid entering the vessel raises the interior pressure above P.sub.1. An output is provided for drawing carbonated liquid out of the pressure vessel. The apparatus is particularly suitable for residential use in providing Seltzer water, where it operates at conventional municipal or private well water pressures.

A selected beverage is delivered to a dispensing station and can either be a carbonated beverage or a non-carbonated beverage depending on the desire of the consumer.

Abstract: A carbonator having a cooling system which is controlled by a controller responsive to input signals generated by an ambient temperature sensor, an ice thickness sensor and a water level sensor. After an initial ice build up following first turn-on of the system and depending on the ambient temperature sensed by the temperature sensor, the cooling system will turn on for a predetermined ON period followed by a predetermined OFF period. These ON and OFF periods are variable as a function of ambient temperature as sensed by the temperature sensor and will recycle in absence of any carbonated water removed. If, however, water removal takes place, the OFF period is interrupted and system turn-on will occur the next time a signal from the ice sensor is received and the ON and OFF cycle as determined by the system controller will resume unless it is again interrupted by another water removal signal from the water level sensor.

Abstract: Apparatus for the low pressure carbonation of beverages by the consumer using a chemical source of carbon dioxide. Low carbonation pressures are achieved by significantly reducing the rate of carbon dioxide gas generation when compared to prior art carbonators. Carbon dioxide is generated by a chemical or chemical combination which will react with water, but does not significantly react when said water is frozen. Embodiment described uses chemical combination of edible acid, carbonate and ice. Reaction occurs gradually when ice slowly reverts to a liquid state. Carbon dioxide is generated in carbonation chamber (10). Gas passes through carbonator cap (12) and into the beverage contained within beverage vessel (16) thus causing carbonation. Chamber (10), cap (12) and beverage vessel (16) are all connected by gas tight means.

Positioning the charging gun so that the receptor fits within the receptor cavity and depressing the manual control button commences the flow of CO.sub.2 gas into the bottle. At a predetermined pressure limit, a pressure regulator renders the continued depression of the control button ineffective and stops the gas flow. The pressure regulating head includes a blow-back plug for preventing matter from the bottle from entering the piston cylinder. A check valve in the cap includes a piston which is sealingly held against a gasket at the upper end of the receptor.

Abstract: A CO.sub.2 gas generator for an aerosol device is located in a housing and chemically generates CO.sub.2 from a chemical reaction between two reagents contained within a common container. The reagents are located in different chambers of the container with a CO.sub.2 accumulation region being included in one of the chambers.

As the CO.sub.2 is withdrawn, the gas pressure drops permitting more mixing of the reagents. When the CO.sub.2 pressure becomes equal to or higher than the predetermined pressure applied by the reference pressure source, the reagents become separated again and gas generation ceases.

Abstract: A gas generator chemically generates a gas from a chemical reaction between two reagents contained within a common container. The reagents are normally separated by a gas generation chamber into different regions of the container in the absence of gas generation therein. A reference pressure source of a predetermined pressure forces the two reagents into contact with each other when the pressure of gas in the gas generation chamber is less than the predetermined pressure.

As the gas flows through the valve from the chamber the gas pressure in the chamber drops permitting more mixing of the reagents. When the chamber pressure becomes equal to or higher than the predetermined pressure applied by the reference pressure source, the reagents become separated again and gas generation ceases.
