Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
55 words
A PROCESS FOR CARBONATING A POTABLE AQUEOUS SOLUTION COMPRISING CONTACTING SAID SOLUTION WITH AN EFFECTIVE AMOUNT OF A POROUS CRYSTALLINE ZEOLITE MATERIAL, SAID ZEOLITE HAVING ADSORBED THEREIN AT LEAST ABOUT 5% BY WEIGHT OF CARBON DIOXIDE, SAID CONTACT TAKING PLACE AT A TEMPERATURE BELOW ABOUT 110*F AND A PRESSURE OF AT LEAST ABOUT 1 ATNOSPHERE.
Claim 2
Dependent Claim
55 words
A PROCESS FOR CARBONATING A POTABLE AQUEOUS SOLUTION COMPRISING CONTACTING SAID SOLUTION WITH AN EFFECTIVE AMOUNT OF A POROUS CRYSTALLINE ZEOLITE MATERIAL, SAID ZEOLITE HAVING ADSORBED THEREIN AT LEAST ABOUT 5% BY WEIGHT OF CARBON DIOXIDE, SAID CONTACT TAKING PLACE AT A TEMPERATURE BELOW ABOUT 110*F AND A PRESSURE OF AT LEAST ABOUT 1 ATNOSPHERE.
Claim 3
Dependent Claim
43 words
A process in accordance with claim 1 wherein the crystalline zeolite material is selected from the group consisting of Zeolite X, Zeolite Y and Zeolite A and pore sizes of the crystalline zeolite material range from about 3 Angstroms to about 10 Angstroms.
Claim 4
Dependent Claim
25 words
A process in accordance with Claim 2 wherein the pore sizes of the crystalline zeolite material range from about 8 Angstroms to about 10 Angstroms.
Claim 5
Dependent Claim
37 words
A process in accordance with claim 2 wherein the crystalline zeolite material has an SiO2/Al2O3 mole ratio of at least 3 and has at least 35% of the exchangeable metal ions thereof removed or replaced with protons.
Claim 6
Dependent Claim
33 words
A process in accordance with claim 2 wherein the aqueous potable liquid is contacted with from about 0.5 to about 4 grams of crystalline zeolite material per fluid ounce of aqueous potable liquid.
Claim 7
Dependent Claim
27 words
A process in accordance with claim 5 wherein the crystalline zeolite material is in the form of spherical beads having a mesh size of 8 X 12.
Claim 8
Dependent Claim
27 words
A process in accordance with claim 5 wherein the crystalline zeolite material is in the form of spherical beads having a mesh size of 4 X 8.
Claim 9
Dependent Claim
51 words
A process in accordance with claim 2 wherein from about 30% to 70% by weight of the crystalline zeolite material has pore sizes of from about 3 Angstroms to about 5 Angstroms, the balance of said crystalline zeolite material having pore sizes of from about 6 Angstroms to about 10 Angstroms.
Claim 10
Dependent Claim
22 words
A process in accordance with claim 2 wherein the crystalline zeolite material is coated with a film of a non-toxic, water-soluble compound.
Claim 11
Dependent Claim
40 words
A process in accordance with claim 1 wherein said porous crystalline zeolite is supplemented with a chemical carbon dioxide producing couple, said couple being present at levels sufficiently low to avoid noticeable quantities of the salts thereof in said beverage.
Claim 12
Dependent Claim
22 words
A process in accordance with claim 10 wherein said couple is sufficient to produce only about 0.5 volume of dissolved carbon dioxide.
Claim 13
Dependent Claim
48 words
A COMPOSITION FOR MAKING A FLAVORFUL CARBONATED BEVERAGE FROM TAP WATER OR THE LIKE COMPRISING A DRY BEVERAGE MIX AND AN AMOUNT EFFECTIVE TO CARBONATE THE BEVERAGE OF A POROUS CRYSTALLINE ZEOLITE SAID POROUS CRYSTALLINE ZEOLITE MATERIAL HAVING ADSORBED THEREIN AT LEAST ABOUT 5% BY WEIGHT CARBON DIOXIDE.
Claim 14
Dependent Claim
48 words
A COMPOSITION FOR MAKING A FLAVORFUL CARBONATED BEVERAGE FROM TAP WATER OR THE LIKE COMPRISING A DRY BEVERAGE MIX AND AN AMOUNT EFFECTIVE TO CARBONATE THE BEVERAGE OF A POROUS CRYSTALLINE ZEOLITE SAID POROUS CRYSTALLINE ZEOLITE MATERIAL HAVING ADSORBED THEREIN AT LEAST ABOUT 5% BY WEIGHT CARBON DIOXIDE.
Claim 15
Dependent Claim
41 words
The composition of claim 12 wherein the crystalline zeolite material is selected from the group consisting of Zeolite X, Zeolite Y and Zeolite A and pore sizes of the crystalline zeolite material range from about 3 Angstroms to about 10 Angstroms.
