Abstract: A method is disclosed of making an internally sensitive photographic silver halide emulsion. In this method further silver halide is laid down on the grains of a surface sensitive or surface fogged emulsion so that excesses of silver and halide ions are alternately produced. In one preferred form a desensitizer is added to the completed internally sensitive emulsion, which desensitizer has a cathodic polarographic halfwave potential less negative that -1.0 volt. In another preferred form a sensitizing dye can be added to the internally sensitive emulsion. The invention is also directed to the silver halide emulsions formed by these methods.

Abstract: AN APPARATUS AND PROCESS ARE DISCLOSED IN WHICH AN EMULSION AND AN ADDENDA SENSITIZER SOLUTION ARE DIRECTED AS SEPARATE FLOWS TO A COMMON JUNCTION WHERE THE FLOWS ARE INTERMIXED INTO A COMMON FLOW UPON COMING INTO CONTACT. THE COMMON FLOW OF EMULSION AND ADDENDA SENSITIZER SOLUTION IS THEN MOVED THROUGH AN EXTENDED PATH WHICH INCLUDES MEANS FOR HEATING THE EMULSION TO A PREDETERMINED TEMPERATURE AND MAINTAINING IT AT SAID TEMPERATUR FOR A PREDTERMINED PERIOD OF TIME AND MEANS FOR COOLING THE COMMON FLOW VERY RAPIDLY, THEREBY FINISHING THE EMULSION AND PROVIDING AN EMULSION OF UNIFORM SENSITIZATION. WHILE THE EMULSION IS BEING MOVED THROUGH THE CONDUIT WHICH FORMS AND DEFINES THE EXTENDED PATH, IT IS BEING MIXED CONTINUOUSLY BY A CONTINUOUS SERIES OF ELEMENTS ARRANGED WITHIN AND THROUGHOUT THE FULL LENGTH OF THE CONDUIT FROM THE COMMON JUNCTION TO AN OUTLET LOCATED BEYOND THE COOLING MEANS.
