Photographic development. (Konishiroku Photo Industry Co., Ltd., Japan). Jpn. 7647-15-6 and 10039-54-0 are also occured in this study. Kokai Tokkyo Koho JP 57190949 A2 24 Nov 1982 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: G03C005-26; G03C007-30. APPLICATION: JP 81-77016 20 May 1981. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Ag halide photog. materials are developed by using developer solns. contg. 2-thiazolylbenzimidazole or 2-(thiazolylmethyl)benzimidazole derivs. The benzimidazole derivs. exhibit excellent development-fog inhibiting properties and also exhibit excellent contrast increase-inhibiting characteristics. Thus, 2-(4-thiazolyl)benzimidazole was added to a color-developer soln. contg. PhCH2OH, ethylene glycol, HONH2.H2SO4, 4-amino-N-ethyl-N-(b-methanesulfonamidoethyl)-m-toluidine sesquisulfate, K2SO3, Na2CO3, K2CO3, NaBr, 1-hydroxyethylidene-1,1-diphosphonic acid, MgCl, hydroxyethyliminodiacetic acid, and a fluorescent brightener. A color photog. paper developed by using the developer soln. showed relatively low g-values and good color balance. .

Mixer for mixing reagents in hydroxylamine sulfate synthesis

Mixer for mixing reagents in hydroxylamine sulfate synthesis. Grzelczyk, Stanislaw; Popowicz, Marian; Berak, Jozef M.; Balcerzak, Kazimierz; Grzegorzewicz, Jozef; Matyja, Kazimierz; Schimmelpfennig, Zbigniew; Gora, Marian (Instytut Chemii Przemyslowej; Zaklady Azotowe "Pulawy", Pol.). Pol. PL 120914 B1 30 Nov 1983, 4 pp. (Polish). (Poland).Several reagents such as 10039-54-0 is used here. CODEN: POXXA7. CLASS: IC: B01F013-02. APPLICATION: PL 79-217311 23 Jul 1979. DOCUMENT TYPE: Patent CA Section: 49 (Industrial Inorganic Chemicals) Section cross-reference(s): 47 The mixer consists of a perforated bell rotating in an aq. H2SO4 soln. contg. a suspension of a Pt catalyst. A (N oxide + H2) mixt. enters the open bottom of the mixer and exits through the perforations. Mixing is improved by installing a rod network between each row of perforations. .
