Methods for producing colloidal oligodynamic metal compositions

Claim 1

A METHOD FOR PRODUCING STABLE AQUEOUS OLIGODYNAMIC METAL DISPERSIONS WHEREIN THE OLIGODYNAMIC METAL IS IN THE FORM OF MICROPARTICLES PREDOMINANTLY OF A SIZE RANGE OF FROM 200 A.U. TO 700 A.U., COMPRISING FORMING AN AQUEOUS SOLUTION OF SILVER NITRATE AND A WATER SOLUBLE CUPRIC SALT SELECTED FROM THE GROUP CONSISTING OF CUPRIC NITRATE AND COPPER SULFATE, UNIFORMLY COMBINING A PROTECTIVE GELATIN IN SAID SOLUTION, AND SIMULTANEOUSLY REDUCING SAID SILVER NITRATE AND CUPRIC SALT TO FORM BOTH ELEMENTAL SILVER AND ELEMENTAL COPPER, THE PROPORTION OF SILVER NITRATE BEING SIGNIFICANT AND NOT EXCEEDING ABOUT 10% OF THE TOTAL WEIGHT OF WATER, PROTECTIVE GELATIN AND SALTS EMPLOYED, THE WEIGHT RATIO OF SILVER NITRATE TO SAID CURPIC SALT BEING FROM ABOUT 1:1 TO ABOUT 3:1, THE PROTECTIVE COLLOID AMOUNTING TO 0.5-2.0% OF SAID TOTAL WEIGHT, AND SAID STEP OF REDUCING THE SALTS BEING EFFECTED BY ACTINIC LIGHT HAVING AN INTENSITY OF A LEAST 45 MILLIWATTS PER SQUARE FOOT, AT LEAST 40% OF THE TOTAL RADIATION BEING IN THE INFRARED PORTION OF THE SPECTRUM, AT LEAST 25% OF THE TOTAL RADIATION BEING IN THE ULTRAVIOLET PORTION OF THE SPECTRUM, AND A MATERIAL PROPORTION OF THE ULTRAVIOLET PORTION OF THE RADIATION BEING EMITTED AT 3130 AND AT 3660 A.U., THE RESULTING OLIGODYNAMIC METAL MICROPARTICLES BEING PREDOMINANTLY OF A SIZE RANGE OF FROM 200 A.U. TO 400 A.U.

Claim 2

A METHOD FOR PRODUCING STABLE AQUEOUS OLIGODYNAMIC METAL DISPERSIONS WHEREIN THE OLIGODYNAMIC METAL IS IN THE FORM OF MICROPARTICLES PREDOMINANTLY OF A SIZE RANGE OF FROM 200 A.U. TO 700 A.U., COMPRISING FORMING AN AQUEOUS SOLUTION OF SILVER NITRATE AND A WATER SOLUBLE CUPRIC SALT SELECTED FROM THE GROUP CONSISTING OF CUPRIC NITRATE AND COPPER SULFATE, UNIFORMLY COMBINING A PROTECTIVE GELATIN IN SAID SOLUTION, AND SIMULTANEOUSLY REDUCING SAID SILVER NITRATE AND CUPRIC SALT TO FORM BOTH ELEMENTAL SILVER AND ELEMENTAL COPPER, THE PROPORTION OF SILVER NITRATE BEING SIGNIFICANT AND NOT EXCEEDING ABOUT 10% OF THE TOTAL WEIGHT OF WATER, PROTECTIVE GELATIN AND SALTS EMPLOYED, THE WEIGHT RATIO OF SILVER NITRATE TO SAID CURPIC SALT BEING FROM ABOUT 1:1 TO ABOUT 3:1, THE PROTECTIVE COLLOID AMOUNTING TO 0.5-2.0% OF SAID TOTAL WEIGHT, AND SAID STEP OF REDUCING THE SALTS BEING EFFECTED BY ACTINIC LIGHT HAVING AN INTENSITY OF A LEAST 45 MILLIWATTS PER SQUARE FOOT, AT LEAST 40% OF THE TOTAL RADIATION BEING IN THE INFRARED PORTION OF THE SPECTRUM, AT LEAST 25% OF THE TOTAL RADIATION BEING IN THE ULTRAVIOLET PORTION OF THE SPECTRUM, AND A MATERIAL PROPORTION OF THE ULTRAVIOLET PORTION OF THE RADIATION BEING EMITTED AT 3130 AND AT 3660 A.U., THE RESULTING OLIGODYNAMIC METAL MICROPARTICLES BEING PREDOMINANTLY OF A SIZE RANGE OF FROM 200 A.U. TO 400 A.U.
