Abstract: A color photographic recording material comprising a support and at least one photosensitive silver halide emulsion layer, with which a yellow coupler of the pivaloyl or benzoyl acetanilide type dissolved in a polymeric ester of aromatic or aliphatic dicarboxylic acids is associated, is distinguished by greater color purity and better dark-fading stability.

Abstract: The production of a photosensitive silver halide emulsion by precipitation of the silver halide in the presence of gelatine, flocculation and washing of the silver halide precipitated in the presence of the gelatine and redispersion with addition of more gelatine, precipitation being carried out in the presence of a gelatine having a gold number of at most 10 .mu.mol/g gelatine and a cysteine content of at most 6 ppm and redispersion being carried out with a gelatine having a gold number of at least 23 .mu.mol/g gelatine, leads to an emulsion of uniform grain distribution in which undesirably high fogging is avoided.

Abstract: The sensitivity/fog ratio can be improved by using photographic silver halide emulsions containing gelatine which has a cysteine content of less than 10 ppm and a gold number of .gtoreq.23 .mu.mol/g.

Abstract: In combination with oil formers of the alkylphenol type, 3-anilinopyrazolones show absorption maxima displaced by about 8 to 12 nm towards longer wavelengths and a blue secondary absorption further displaced towards the UV range and, hence, a reduced yellow secondary density.

Abstract: A device for enriching a fluid with ozone includes an inner tubular member arranged within an outer tubular member and defining a separate flow path for a fluid within the inner tubular member and another one for a fluid between the inner and outer tubular members. An electrode which has a high voltage regulation and a coil portion which extends through the inner tubular member forms a grounding electrode. A fluid such as air which is to be enriched with ozone is passed either through the inner tubular member or the space between the two tubular members and a cooling fluid is passed in the other tubular member. The inner tubular member is made of an ultraviolet penetrable and heat resistant material such as quartz glass.
