Photographic reducer

The micro Ringleman This is a photographically reduced Ringleman (i.e. with cross-hatching). It has a slot in the middle through which the smoke can be viewed at arm s length. 

Uses Antioxidant photographic reducer and developer for black and white film determination of phosphate dye intermediate medicine in monomeric liquids to prevent polymerization stabilizer in paints and varnishes motor fuels and oils. 

Uses. Photographic reducer and developer antioxidant stabilizing agent for some polymers intermediate in the manufacturing of some dyes and pigments in cosmetic formulations...

An unexpected assist Ray Firmani, the photographer for Jackson Laboratory, on learning of my problems, responded to a question about whether there were some photographic reducing agents that did not discolor. He asked me if I had ever considered phenidone. I had not even heard of phenidone (3-IV-phenylpyrazolidinone) (Scheme 4.11), but Ray obtained an ounce from a camera shop, and we fixed and had no background problems thereafter. No one had ever...

Photographic reducer and developer reagent for the determination of small quantities of phosphate, dye intermediate stabilizer in paints and varnishes motor fuels and oils antioxidant for fats and oils, and a polymerization inhibitor. Therapeutically used topically for depigmentation to treat skin blemishes, for example, hypermelanosis. Hydroquinone occurs naturally, as a conjugate with jS-o-glucopyranoside, in the leaves, bark, and fruit of a number of plants, and its presence may be an important factor in fire-blight resistance in the pear. It may also play an important part in the defense mechanisms of some insects. 

Microfiche. Cards are photographically reduced and printed on 4 x 6 in. (10 X 15 cm) sheets of photographic film (microfiche). With 116 cards on each microfiche, storage space is much reduced but a microfiche reader is required. 

The first photographic reducer used to destain silver-stained polyacrylamide gels employed ammonium hydroxide, copper sulfate and sodium thiosulfate (1 ). It is also a subproportional reducer. The diamine stains are most resistant, while the photodevelopment stains are most sensitive to destaining.

Au, Fe, and Cr sols were prepared by the reduction of their hydroxides by hydrazine hydrate in a matrix of water-soluble polymers, and dispersions of particles of Pd (1-2 nm) and Au (1-13 nm) were obtained in synthetic rubber films. Polymeric films prepared from aqueous solutions of PVAl and AgNOs were treated with photographic reducing agents (hydroquinone, p-phenylenediamine, pyrogallol, etc.) to produce die corresponding metallocomposite materials. Monodispersed hyperfine powders of gold and platinum were prepared by the reduction of...
