Title: Improvements in colour photography
IPC: G03C7/30
Filed: 1936-09-04
Abstract: 486,848. Colour photography. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Sept. 4, 1936, No. 24225. [Class 98 (ii)] Multi-colour pictures are produced by using for both exposure and copying, materials provided with silver halide emulsions which are sensitive to different spectral regions and contain colour formers which are derived from bodies known to be capable of combining with the oxidation product of the developer to produce a coloured compound, by the introduction into such a body of a group which renders the colour former fast to diffusion, the materials being subjected to colour development. One of the layers may however contain no colour former and be carried on the other side of the support, the desired colour being produced by toning. In one example, a topmost layer is non sensitized and contains the dianiside of acetoacetic acid ; the next layer sensitized to green contains the symmetrical urea of 1 (para aminobenzoyl-metaaminophenyl)-3-methyl-5-pyrazolone, and the third layer sensitized to red contains the benzidide of alpha-naphthoic acid. The film is developed by using paraaminodimethylaniline and copied by contact onto similar material. Alternatively the film is first developed to black and white by 2: 4-diaminophenol developer, and the residual silver halide is colour developed with paraaminodimethylaniline. The silver is removed by treatment with Farmer's Reducer. In another example. the blue sensitive, green sensitized and red sensitized layers respectively contain as colour formers the yellow-forming sodium parastearylaminobenzoyl acetanilide - paracarboxylate ; the blue-green forming 1-N -stearyl-4-N -(1<1>- oxy-2<1>-naphthoyl) phenylene diamine sulphonate and the purple forming 1-(31-sulphophenyl ) - 3 - (4<11> - stearylaminophenyl) - 5- pyrazolone in the form of the sodium salt. The film is developed by paramino-dimethylaniline and copied on to similar material. Material having the red sensitized layer between the green sensitized and blue sensitive may be used for either exposure or copying. It is not necessary that the exposure material should be produced in correct colour, there being examples in which the correct colours are obtained only in the final copy. Another colour former specified is sodium meta stearylaminobenzoylacetanilide - para - carboxylate, which is a yellow component. Specifications 376,795, 458,400, 465,823, and 479,838 are referred to. The Provisional Specification also refers to Specifications 488,853 and 436,587.

Title: Water soluble cellulose ethers and their production
IPC: C08B11/08
Filed: 1964-06-11
Abstract: In a process for producing a water-soluble cellulose ether, cellulose is pre-treated with an alkyl halide, acrylonitrile or a halogenated acetic acid or a salt thereof in the presence of alkali and water until a D.S. of 0.05-0.5 is attained, the amount of alkali contained in the pre-treated cellulose is reduced to less than 10% based on the weight of the pre-treated cellulose, and the pre-treated cellulose is contacted with a gaseous alkylene oxide in the presence of said reduced amount of alkali until an M.S. value of more than 1.0 is attained.  The pretreatment may be conducted in liquid or gaseous phase. Cellulose pulp may be treated with a 15-25% aqueous solution of caustic alkali, the product squeezed to a press ratio of 1.5-4.0, and the resulting alkali cellulose, containing 20-200% of alkali, reacted in a closed vessel with gaseous alkyl halide acrylonitrile or halogenated acetic acid or salt thereof, to yield a substantially water-insoluble product of D.S. 0.05-0.5. Excess alkali may then be removed by diluting the reaction product with water, and pressing the mixture to a ratio of e.g. 2-3, so that the alkali content of the pretreated cellulose is reduced to the required amount.  Reaction with the alkylene oxide may be effected by admitting the gas from a pressurized vessel into an evacuated vessel containing the pre-treated cellulose, the reaction temperature being maintained at e.g. 15-35 DEG  C.  The reaction may be initiated at a lower temperature and completed at a higher temperature.  Termination of the etherification may be effected by removing the residual alkylene oxide and neutralizing the alkali, preferably by gaseous carbon dioxide, sulphur dioxide or methyl acetate.  The reaction product may be dried and pulverized without washing or purification.  Examples describe the preparation of methyl cellulose, ethyl cellulose, cyanoethyl cellulose and carboxymethyl cellulose, and their further etherification with ethylene and propylene oxides.

Abstract: 431,818. Force - feed lubricating. DIENY, A. E., 6, Rue A. Dailly, Viroflay, Seine-et-Oise, France. Aug. 24, 1934, No. 24412. Convention date, Sept. 8, 1933. [Class 12 (iii)] [See also Group XVIII] A device for delivering measured quantities of lubricant or other liquids of the kind operated by the pressure of the liquid comprises an admission piston c moving in an admission chamber a and one or more exhaust pistons c<1> moving in exhaust or outlet chambers a<1>, the chambers communicating with each other by passages through which liquid passes from the admission chamber to the outlet chamber or chambers when a decrease of pressure occurs in the inlet, the measured quantity or quantities being ejected from the outlet chamber or chambers when the pressure again increases. As shown in Fig. 1, an abutment b divides a cylinder h into admission and outlet chambers a, a<1>. Increase of pressure in the inlet g forces up the piston c and allows liquid to pass through a pipe e and force up the piston c<1>. When the inlet pressure decreases the piston c moves down under the action of its spring so as to close the orifice of the pipe e and uncover the inlet of a pipe f. As the piston c<1> is moved down, the liquid between the pistons is forced through the pipe f to above the piston c<1> which expels it through the outlet d on the next increase of pressure at the inlet. The position of the lower end of the outlet d may be varied to alter the stroke of the piston c<1> and therefore the amount of liquid delivered. In a modified form, Fig. 9, several outlet chambers with pistons c<1>1, c<1>2, are provided. During the downward movements of these pistons, the liquid is first forced into a reserve chamber j, compressing the air above it and passes from this chamber to the separate outlet chambers when the pistons have reached their lowermost positions.
