Title: Coloured photographic layers
IPC: G03C1/825
Filed: 1941-07-18
Abstract: 550,028. Coloured photographic layers. TULL, A. G. July 18, 1941, Nos. 9097/41 and 2585/42. [Class 98 (ii)] A coloured photographic layer contains a dye lake formed by the mutual precipitation of a basic dye and an acid dye and which is soluble in excess of an acid dye, which need not be one of the components of the lake. The coloured layers may be used as antihalation layers or as filter layers. The lake may be formed in a mass of gelatin solution, by mixing gelatin t solutions containing, the dyes, by dissolving the lake in an organic solvent, or by making successive coatings containing the reacting dyes, the first coating being preferably a gelatin layer. The lake may. be formed by the reaction of a basic dye with Tartrazine, and a coloured layer containing such lake is decolourised by bathing in an aqueous sotution of Tartrazine. An organic solvent such as methyl alcohol may be added to assist decolourization. Dispersing agents may be used to effect dispersion in gelatin. Suitable basic dyes are Auramine O, Acronol Yellow TC, Chrysaniline, and Rhodamine B, and suitab!e acid dyesare Tartrazine, Xylene Light Yellow 3GS, and Victoria Scarlet. A 2 to 4 per cent bath of Tartrazine, which may contain 30 per cent methyl alcohol, may be used as a discharge bath. In Example 1; an aqueous solution of gelatin is mixed with a solution of Acronol Yellow TC in a chlorinated alcohol (e.g: chlorbutol) and methyl alcohol, and an aqueous solution of Tartrazine is added. The mixture is used for coating a filter layer. In example 2, an aqueous solution of gelatin is mixed with an aqueous-methyl alcoholic solution of Acronol Yellow TC, and the mixture coated ; a second layer of, gelatin containing. Tartrazine is applied. In multilayer material, the two dyes may be added to contiguous emulsion layers, to produce a' filter layer at the boundary surface. The first dye may be in a gelatin or silver halide emulsion layer, and the second dye applied in aqueous or alcohol solution. One coating may contain one dye and the other the second dye to which enough of the first dye has been added to bring. the mixture, near the precipitation point. In example 3, a layer of gelatin containing Acronol Yellow TC isfollowed by a layer of gelatin containing Victoria Scarlet and a little Acronol Yellow TC. The acid dye'may be coated first. The basic dye may be employed as the free base, and the sulphate is sometimes preferable to the chloride or hydrochloride: The. coated' layers may be rendered slightly alkaline with ammonia or borax. The first dye may be applied in alcoholic solution, and the second in alcoholic or aqueous solution or in gelatin or an emulsion coating mixture. A coloured layer may be produced on the surface of an already coated gelatin or silver halide emulsion layer by applying the first dye in aqueous or alcoholic solution and the second similarly or in a further gelatin or silver halide emulsion coating. Decolourization may be effected after coloured images have been produced in multilayer material.

Abstract: 804,418. Frequency converters. SIEMENSSCHUCKERTWERKE A.G. March 25, 1957 [March 23, 1956], No. 9742/57. Class 35. [Also in Group XXXVII] A frequency converter for supplying traction motors 1, 2, through rectifier 4, has a single-phase primary winding 6 and a sixphase secondary winding 5, these windings being placed on the stator of the machine and having different pole-numbers so that there is no interaction between the windings. The frequency of the output of the winding 5 is a multiple of the supply frequency. The converter also has two separately-regulated rotor windings 8, 9, of different pole-numbers, which are excited with direct-current. The secondary voltage of the converter is regulated by means of resistor 10 in series with winding 9 which is wound on poles 2<SP>1</SP>, 5<SP>1</SP>, whilst the primary current is controlled by resistor 11 in series with winding 8 which excites the poles 1<SP>1</SP>, 3<SP>1</SP>, 4<SP>1</SP> and 6<SP>1</SP>. For regenerative braking, the rectifier (which may be grid controlled) is changed over to inverter operation, the control of the braking current being effected by variation of the excitation of the converter. A damper winding in slots 12 serves, at the same time, as a starting cage. In another arrangement, the stator of the converter is provided with a single winding which combines the functions of the primary and secondary windings, a step-down transformer being connected between the line and the stator winding. The converter, which may have a vertical shaft, may also be used as a synchronous motor for driving a generator supplying auxiliary loads on the vehicle.
