Title: A method of producing cycloalkanone oximes which are difficultly soluble or insoluble in water
Filed: 1963-09-06
Abstract: In the manufacture of cycloalkanone oximes which are difficultly soluble or insoluble in water from a cycloalkanone and an aqueous acidic solution of a hydroxylamine salt at a temperature above the melting point of the oxime, a cycloalkanone fed to the bottom of a reaction column is caused to flow in countercurrent to an aqueous acidic solution of a hydroxylamine salt fed to the top of the column, and a mixture of ammonia and an inert gas is fed to the column at two or more intermediate points. As shown, a cycloalkanone is fed at 2 to a packed column 1 and an aqueous acidic solution of a hydroxylamine salt is supplied at 3. A mixture of ammonia and an inert gas is supplied at three points 4, preferably in such a way that the pH value of the reaction mixture rises steadily from 2 at the head of the column to 7 at the foot. The oxime is withdrawn at 5 and an ammonium salt solution at 6.  Examples are given of the manufacture of cyclohexanone oxime and cyclopentanone oxime. <PICT:1013968/C2/1>

Title: Photographic process and materials therefor
IPC: G03F7/008
Filed: 1972-08-02
Abstract: 1404370 Photographic and thermographic materials EASTMAN KODAK CO 2 Aug 1972 [2 Aug 1971(2)] 36023/72 Heading G2C A negative dye image is made by imagewise exposing a supported layer of a radiation sensitive complex of a triorganophosphine (as defined below) and an organoazide and reacting the imagewise distributed product with a dye-forming coupler, the triorganophosphine being defined as a compound comprising three organic groups bonded to a phosphorus atom. The dye image is stabilized by heating and the coupler may be present in the layer or applied after imagewise exposure. The layer may contain a binder such as vinyl and acrylic polymers, cellulose ethers and esters, polyesters and epoxy resins. Specified couplers are those set out in Table 3. Positive images are produced by imagewise thermal exposure which is then followed by an overall exposure to U.V. radiation for the complex and, if no coupler is present in the layer, treatment of the layer with a coupler solution. In another modification the support may be coated with a layer containing the azide and an alkali and the layer then treated with the phosphine precursor, e.g. phosphonium salts, to release the phosphine and form the complex prior to exposure to activating radiation. An image comprising two dye images may be obtained by (a) imagewise exposing photographic sheet material coated with a layer containing the phosphine precursor, a p-disubstituted amino phenyl azide and a coupler to actinic radiation to form a first dye image, (b) treating the material with an alkali to release the phosphine and form a complex, (c) imagewise exposing the material to actinic radiation to form a second dye image and (d) heating the material uniformly to effect stabilization. By coating a radiation-sensitive layer capable of giving a two colour image on each side of a transparent support and providing a substantially colourless U.V. absorber in the support or in a separate layer between the support and one of the radiation sensitive layers a four colour material can be formed.

Abstract: 1,249,104. Photographic type-composing. J. M. CLARKE. 8 Oct., 1968 [7 Aug., 1967], No. 36130/67. Heading B6W. There are mounted on a glass screen 11 a master sheet 48 bearing a hand-made layout of matter to be printed, and a photo-sensitive sheet 49. Above the sheets is a beam 13 slidable along guide-rods 12, and slidable along the beam are a slide 31 carrying a cursor 33 and a slide 19 on which is slidable a cross-slide 25 supporting a character matrix plate 27 having rows of transparent characters of various styles and sizes, upper and lower case, each character having a width indicating mask 29a beneath. The cursor includes an opaque (except to red) film having a plurality of clear areas in the form of parallelograms of different inclinations and heights, and a rotatable disc having a straight edge defining an aperture in the disc. To reproduce a character, hair-lines at the left end of the cursor are aligned with the character on the original, the plate 27 is moved to bring the required character into the aperture, the size and alignment of which is adjusted by rotating the disc and moving the film running on reels 39 to select a particular clear area. A light-source means 36 is mounted on the cursor, and the light is flashed for reproduction. This process is repeated for each character. Having selected a style and size for a line, stops 30 are set limiting the movement of the slide 25 so that its extreme positions bring the upper and lower case lines selected into reproduction position. By carrying out the aligning process for a whole line without using the light source, the amount of justification necessary can be calculated. The cursor is moved in linelength direction by a calibrated disc through a one-way drive means, so that the disc can be reset to zero after each operation. Stops 50, 51 are set to indicate the beginning and end of the line. (For Figure see next page.)
