Title: Sensitive photographic emulsions
IPC: G03C1/28
Filed: 1947-04-18
Abstract: 635,366. Supersensitized silver bromide emulsions. KODAK, Ltd. April 18, 1947, No. 10453. Convention date, April 20, 1946. [Class 98 (ii)] A silver salt emulsion containing silver bromide is supersensitized with a mixture of a cyanine dye which produces a second sensitization maximum at a wavelength longer than that of the first maximum at a higher concentration or upon digestion of the emulsion at the same concentration, and benzimidazole or a substituted benzimidazole base. The benzimidazole base may be substituted by a halogen atom or by an alkyl, alkoxy, hydroxyalkyl, aryl, aryloxy, alkylmercapto, arylmercapto, acyl, or acyl oxy group. Compounds specified are benzimidazole, and 1-, 2-, 4- and 5-methylbenzimidazole, 1- and 2-phenylbenzimidazole, 1-acetylbenzimidazole, and 5-methoxybenzimidazole. More than one cyanine dye and more than one benzimidazole base may be used. Cyanine dyes specified include 1 : 1<SP>1</SP>- diethyl-2 : 2<SP>1</SP>-cyanine bromide, 1 : 1<SP>1</SP>-diethyl- 2 :2<SP>1</SP>-carbocyanine bromide, 3 : 11-diethyl-61- methoxythia-2<SP>1</SP>-cyanine bromide, 1<SP>1</SP>-ethyl-3:6<SP>1</SP>- dimethyl - 4 - phenylthiazolo - 2<SP>1</SP> - cyanine bromide, 5<SP>1</SP> - chloro - 3 : 3<SP>1</SP> - 9 - triethylthiacarbocyanine iodide, 3 : 3<SP>1</SP>-diethyl-9-methyl- 4 : 5 : 41 : 5<SP>1</SP> - dibenzthiacarbocyanine bromide, 3 : 3<SP>1</SP> - diethyl - 9 - methylselenacarbocyanine bromide, 3 : 3<SP>1</SP> - diethyl - 9 - methyl- 5 - phenyloxathiacarbocyanine iodide, and 3 : 3<SP>1</SP>-diethyloxatricarbocyanine iodide. The base may be added to the emulsion before, simultaneously with, or after the addition of the dye. The emulsion may contain a. binder other than gelatin, and the silver halide may be silver bromide, chlorobromide, or bromiodide. Some bases cause a decrease of sensitivity at other spectral regions. In examples, gelatino silver chlorobromide and bromiodide emulsions are sensitized with a mixture of 3 : 3<SP>1</SP>-diethyl- 9-methylselenacarbocyanine bromide and, respectively, benzimidazole and 2-methylbenzimidazole. Specification 515,372 is referred to.

Title: Improvements in printing and other textile treatments
Filed: 1935-04-04
Abstract: Printing; cellulose esters or ethers or regenerated celluloses, dyeing.--A dyestuff is fixed in selected areas of a textile material by applying, to the said areas only, two or more substances adapted to react together to form a substantially water-insoluble nitrogenous resin and causing such substances to react over the said areas.  The process described in Specification 450,516 is excluded.  A cir<\>ae finish may be imparted, e.g. by hot calendering, after the application of the reagents and, in that case, the dyestuff may be omitted or may be applied in admixture with the reagents.  Dyestuff may be removed from parts of the material other than the said areas by simple washing or by treatment with hydrosulphite after the formation of the resin. The process is applicable for producing coloured cir<\>ae effects on cr<\>zepe fabrics.  Specified resins are (a) those from aldehydes or ketones, e.g. formaldehyde, acetaldehyde, benzaldehyde or acetone, and aliphatic or aromatic amines or amides, e.g. urea, thiourea, guanidine, dicyandiamide, aniline, methylaniline, diphenylamine, benzylaniline, b -naphthylamine, p-toluenesulphonamide and N-alkyl or other derivatives thereof; (b) condensation products of formaldehyde with gelatine, casein or other albuminoids; (c) the condensation product of phenol with methylenediphenyldiamine.  The following examples are specified: (1) a fabric of natural silk or of viscose or acetate artificial silk is printed or sprayed over the whole surface with a composition containing Acid brilliant blue EG or Acridine red 3B, water and gum and, after drying, is over-printed with an aqueous paste containing urea or thiourea, formaldehyde, formic acid and gum, dried, stoved at 110 DEG  C., washed with hot water and cleared with sodium hydrosulphite at 70--80 DEG  C.; the dyestuff is fixed only in the over-printed areas; (2) a similar fabric is printed with a composition containing urea or thiourea, formaldehyde, formic acid, Erie green WT or Cyanol FF, water and gum and the printed fabric is dried, given a cir<\>ae finish, stoved at 110 DEG  C. for 1--2 hours and washed in cold water; the printed areas only retain the cir<\>ae finish.  The Provisional Specification refers additionally to (a) fixation of colour and cir<\>ae effects over the whole material, (b) application of dyestuff or of a cir<\>ae finish after the formation of the resin, (c) application of an initial condensation product in place of the mixture of components for forming the resin.

Abstract: <PICT:1025819/C6-C7/1> Germanium is successively epitaxially deposited on and etched from a substrate 11 of Ge, GaAs, GaP or InSb by reacting HI in a H2 and He gas stream with a heated Ge bed 9 and passing this stream over the substrate at a lower temperature than the bed 9. Pulsed UV light from a Xenon source 12 irradiates the substrate Ge being deposited when the light is off and removed when the light is on, the pulse frequency may vary during the process.  HI is formed by passing a mixed controlled flow of H2 and He through a heated iodine crystal bed 4 and then through a platinum wool catalyst chamber 8.  In one example a single crystal substrate is continuously irradiated and the surface etched by the gas stream.ALSO:<PICT:1025819/C1/1> In a method of depositing Ge (see Division C7) HI is formed by passing a mixed controlled flow of H2 and He through an iodine crystal bed 4 in a thermostatically controlled oil bath at 50 DEG  C. and then through a platinum wool catalyst chamber 8 at 300-400 DEG  C.

Abstract: A method according to the parent Specification wherein S ore, containing 50-75% S, of a size below 80 mesh is purified by feeding 2 discrete streams into a vessel containing stirred water, the first stream being the ore at above 265 DEG F. and containing molten S and the second stream being a mixture of H2O at above 200 DEG F. and solid S particles, the the mixture of H2O and S particles whose solidification has begun are discharged at 212 DEG F. from the vessel and cooled in at least one further vessel before being fed to a classifier to separate S of greater than 80 mesh size.  The S before being melted may be comminuted to less than 320 mesh and contains gangue, e.g. water-insoluble inorganic compounds such as siliceous material.  The water to solids weight ratio may be from 4-7:1 or for a batch process down to 1 1/2 :1.  A mixer, of or lined with Al, Pb or glass, with a stirrer, e.g. inverted hollow cone, is charged with H2O at 200 DEG -212 DEG F.  The molten S is fed into the mixer, e.g. into the eye of the stirrer, together with a stream of H2O at 200 DEG -212 DEG F. containing S crystals which may be derived from the process. Gangue is separated from the S which forms globules of 30-60 mesh. An overflow of S, gangue and H2O is gravity fed to a vessel where it is cooled to 150 DEG F. and may then be fed to further coolers.  Stirring is desirable in all coolers.  The classifier may be a counter-current type.  Specification 912,164 also is referred to.
