  • Morphology control of substituted diacetylenic monomers for shelf life monitoring systems
    Patent number: 7161023
    Abstract: A system for recovering a diacetylenic monomer shelf life monitoring compound of reduced particle size and narrow size distribution range which comprises quenching a solution of the monomer by mixing the solution in a lower temperature quenching fluid having a base temperature which is at least about 30° C. below the nominal temperature at which the monomer compound recrystallizes from solution, the mixing being effected in such a manner as to limit the resulting quenching mixture temperature to one which is not higher than a maximum of about 15° C. above the quenching fluid base temperature.

  • Silver halide photographic emulsions sensitized in the presence of organic dichalcogenides
    Patent number: 5219721
    Abstract: This invention provides a method of preparing a silver halide photographic emulsion which comprises adding to the silver halide emulsion before or during sensitization a non-labile chalcogen compound represented by Formula I:R.sup.1 --X.sup.1 --X.sup.2 --R.sup.2 (Formula I)It further provides a silver halide photographic emulsion prepared by the above method.
