Title: Improvements in process for stabilizing prints obtained by the photographic bleaching-out process
IPC: G03C7/02
Filed: 1939-12-12
Abstract: 597,147. Photographic bleach-out processes ; colour photography. POLGAR, A., and HALMOS, C. Dec. 12, 1939, No. 32073. Convention date, Dec. 15, 1938. [Class 98 (ii)] Prints made by the bleach-out process on material sensitized with thiocarbamide derivatives are fixed by insolubilizing the dyes, substantially eliminating the sensitizer by washing, and precipitating the traces of sensitizer remaining. Alternatively, the exposed material may be treated in an aqueous bath containing a cation-active long-chain quaternary ammonium salt and/or a water-soluble inorganic substance, such as a derivative of mercury, tin, silicon, tungsten or molybdenum, having the property of rendering the bleach-out dye more resistant to water or more water-insoluble and also of precipitating the sensitizer. In a modification, the quaternary ammonium salt or inorganic substance may be incorporated in the bleach-out layer and the latter treated with water after exposure. The sensitizing activity of the thiocarbamide derivatives may be destroyed by treatment with derivatives of tungsten or mercury. With basic dyes, a mixture of silicotungstic acid and a chlorostannate insolubilizes the dyes and destroys the sensitizing activity of the sensitizers at the same time. A thiocarbamide derivative may be precipitated by treatment with mercuric chloride solution or dissolved out by treatment with a solution containing mercuric chloride and thiocarbamide. These substances may also be incorporated in the bleach-out layer. The dyes may also be insolubilized by treatment with an acid solution of ammonium molybdate, which may also be incorporated in the layer. In example (1), exposed paper sensitized with basic dyes and a thiocarbamide is treated with a solution of ammonium chlorostannate and silicotungstic acid and is then washed. In example (2), the paper is merely wetted with the solution and is then dried. In example (3), exposed paper containing Naphthionic Red, oxalic acid and diethanolallylthiocarbamide is coated with " Solidogen B " (Registered Trade Mark) and is then washed. In example (4), three-colour bleach-out paper containing basic dyes and thiocarbamide derivatives is treated successively in acidified mercuric chloride solution and then in thiocarbamide solution. In example (5), exposed paper coated with a layer containing gelatin, hydrochloric acid, Nile Blue sulphate, Flavindulin O, Sulphopyronine G, acetamide, oxalic acid, diethylallylthiocarbamide and mercuric chloride is merely washed with water. In example (6), exposed material comprising a transparent support coated with a layer comprising polyvinyl alcohol, Capri Blue, Dimethoxyresorcinebenzeine chloride, Sulphopyronine, Diethanolallylthiocarbamide, oxalic acid, sulphuric acid, acetamide and ammonium molybdate is successively washed in aqueous solutions of ammonium molybdate and silicotungstic acid, is rinsed with water and is dried.

Abstract: 965,746. A.C. motors. SANGAMO WESTON Ltd. Aug. 30, 1960 [Sept. 22, 1959], No. 32267/59. Heading H2A. A device for preventing a small synchronous motor from running in the wrong direction comprises a locking sprag member 30 used in conjunction with pinion 36 and stop-plate 37. Pinion 36 is a light frictional drive on the motor shaft and meshes with gearing 33 on sprag 30 so that either abutment 34 or 32 is driven against the teeth of pinion 36. When abutment 34 is adjacent the teeth stop 38 can revolve freely clear of abutment 32 and the motor will run in this direction. If, however, abutment 32 is against the teeth, stop 38 will hit it and stop the motor which will then reverse on the next half-cycle of the supply and revolve in the correct direction. The direction of rotation can be changed by meshing the other teeth 33 on the part with pinion 36. The sprag member is preferably a one-piece nylon moulding. The motor has a permanent magnet rotor with an even number of equi-spaced major poles 27, each comprising two minor poles 28 having the same polarity and co-operating with an even number of equi-spaced stator teeth having opposite polarity on adjacent teeth when the motor is energized from a single phase supply. The arcuate width of the minor poles equals the angle subtended between mutually facing edges of similarly poled stator teeth and the spacing between these mirror poles is equal to the angle subtended by an odd number of stator teeth. The stator assembly comprises two open cylindrical cups one being axially longer than the other and surrounds the energizing coil which is itself moulded within aprotective interlocking insulating casing all assembled on a central stationary core member, Fig. 2 (not shown).

Convention dates, Dec. 24, 1938, Jan. 3, 1939, and Feb. 14, 1939. [Class 2 (iii)] α-#-Diaryl-α-#-dialkyl ethane compounds in which the aryl group is substituted by hydroxy, alkoxy, aryloxy or acyloxy groups are prepared by subjecting to a thermal decomposition compounds of the general formula where of the four free valencies, two adjacent ones form with each other a double bond, while the remaining two are bound to hydrogen. The thermal de-composition preferably takes place in the presence of a de-hydrogenating catalyst such as palladium sponge, but it may be carried out by a direct heating under reduced pressure. The starting materials for the invention may be prepared from corresponding ketazines which have the formula >C=-N-N=C<, by hydrogenation with spontaneous oxidation or by hydrogenation followed by a mild oxidation, or from aldazines by the action of alkyl magnesium compounds. The mild oxidation is necessary because the hydrogenation of the ketazines produces hydrazino compounds of the formula >CNÀNHÀNHÀCH< and it may be carried out by the use of a mild oxidizing agent such as shaking in an atmosphere of oxygen in the presence of copper sulphate. Frequently, however, the oxidation will take place spontaneously if air is not excluded from the re-action ingredients, and in such a case a separate oxidation step is not necessary. The compounds of the invention have a small but extremely protracted oestrogenic action which can be considerably increased by disalkylation with, for instance, concentrated hydrobromic acid or alcoholic potassium hydroxide. The free phenols may be acylated by for example acetic anhydride or acetyl, propionyl, stearyl or benzoyl chloride. In examples, (1) p- Hydroxy-propiophenone-ketazine is hydrogenated and then heated under reflux with palladium sponge. By fractionation of the product there is obtained γ-#-di-(p-hydroxyphenyl)- hexane. (2) p-Methoxy-propiophenone ketazine is hydrogenated in the presence of palladium in alcoholic suspension and the product distilled in vacuo to give γ-#-di-(p-methoxyphenyl)- hexane. On disalkylation with alcoholic potash a product is obtained identical with that obtained by. the process of example (1). (3) p- Methoxy-propiophenone-ketazine is treated as in example (2) to give di-(p-methoxyphenyl)- diethyl ethane which may be isolated by crystallization in two isomeric forms. (4) p- Hydroxy-propiophenone ketazine is hydrogenated in the presence of palladium on charcoal, the product oxidized with iodine and subjected to thermal decomposition to give di-(p-hydroxyphenyl)-diethyl ethane. (5) Anisaldazine is treated with magnesium ethyl bromide and the product thermally decomposed to give di-(p-methoxyphenyl)-diethyl ethane.
