Title: The manufacture of more dyeable regenerated cellulose filaments
Inventor: TOMS BRYAN ATKINSON
IPC: D01F11/02
Filed: 1967-12-13
Abstract: 1,243,194. Regenerated cellulose filaments. COURTAULDS Ltd. 12 Dec., 1968 [13 Dec., 1967], No. 56592/67. Heading B5B. [Also in Division C3] Regenerated cellulose filaments of enhanced dyeability having an amino-nitrogen content of at least 0À06% by weight incorporate aminoethyl cellulose containing at least 2% by weight of amino nitrogen, and are made by mixing a solution in water or aqueous caustic soda of the above amino-ethyl cellulose with a viscose to form a modified viscose which is then extruded through a multi-hole jet into a spin bath when the nitrogen content of the aminoethyl cellulose is below 4% by weight preferably between 2À7 and 3À3 it is dissolved in aqueous NaOH; at 4% and above it may be dissolved in water. In the latter case the freshly coagulated filaments may be stretched by at least 60% of their original length or cross-linked in order to prevent the water soluble aminoethers from being leached from the filaments when they are immersed in hot dilute acids.

Abstract: 1,237,196. Linings for garments.  BONDINA Ltd. 27 Nov., 1968 [15 Dec., 1967], No. 57143/67. Heading A3V. A lining or interlining for garments that are folded when in use, e.g. collars and cuffs, particularly of shirts, is formed by laminating together two fabrics with an intermediate layer of thermoplastic polymeric material, the fold line being defined by one or more gaps in the adhesive layer. The fabrics may be woven or non-woven and the adhesive is preferably a sheet of polythene, the fold line, which may be curved, being defined by slits in the adhesive layer, preferably about 3/32 inch wide. The thermoplastic layer may be formed on one of the fabrics by applying a powdered or printed adhesive. The process may be carried out by prelaminating the thermoplastic sheet with one  fabric, then combining the second fabric with the prelaminate.

Abstract: 1,200,929. Preparation of lactams from cycloalkanes. STAMICARBON N.V. 15 Dec., 1967 [16 Dec., 1966], No. 57155/67. Heading C2C. #-Lactams are prepared by a photochemical process which comprises reacting under the influence of radiation at a temperature of -10-90‹ C., in a liquid phase, nitrosyl chloride (or a mixture of NO and Cl 2 ) hydrogen chloride and a cycloalkane in which a nitrile has been dissolved, the said nitrile being one which does not react with nitrosyl chloride, the proportion of nitrile being maintained at at least 1 mole per mole of nitrosyl chloride, heating the resulting product to a temperature of 40-150‹ C. to form the #-lactam corresponding to the cycloalkane. The nitrile may be benzonitrile, didichloro - acetonitrile, trichloro - acetonitrile, a chlorobenzo - nitrile or α- or #- naphthonitrile and Cl 2 * may be introduced to promote a smooth reaction. This photonitrosation of the cycloalkane results in the formation of a cycloalkyl-imino-α-imino alkyl ether or a cycloalkylimino-α-imino aryl ether from the aliphatic or aromatic nitrile respectively. The product may be converted to the corresponding lactam by heating at 40-150‹ C.

Title: Electrolyte Circulation in Galvanic Cells
IPC: H01M8/04
Filed: 1966-12-30
Abstract: 1,165,350. Electrolyte circulation in a galvanic cell. ALLMANNA SVENSKA ELEKTRISKA A.B. 30 Dec., 1966 [31 Dec., 1965], No. 58273/66. Heading H1B. Electrolyte is circulated in a galvanic cell by means of a first storage vessel connected to the lower part of the electrolyte chamber by a conduit for one-way flow of electrolyte to the chamber and a second storage vessel connected to the upper part of the electrolyte chamber by a conduit for one-way flow of electrolyte to the vessel from the chamber and to the first storage vessel by a conduit outside the cell for one-way flow of electrolyte from the second to the first storage vessel, the flow of the electrolyte being effected by varying the gas pressure above the electrolyte in at least one of the storage vessels. As shown in Fig. 1, the pressure in the first vessel 10 is varied by a throttle valve 20 in the gas conduit 18; a rise in pressure forces electrolyte through the conduit 9, the electrolyte chamber 4 and conduit 11 to the second vessel 12; lowered pressure results in flow of electrolyte under hydrostatic pressure from vessel 12 through conduit 21 to vessel 10. In Fig. 2 (not shown), the gas pressure in vessel 12 is variable as in vessel 10 and one-way flow is obtained by inserting non-return valves in conduits 21 and 9 or 11. In Fig. 3 (not shown), gas from the fuel exhaust 6a, via a reducing valve, is used as the pressure-varying gas in vessel 10. In Fig. 4 (not shown), the pressurevarying gas is led into the electrolyte chamber to flush out possible dangerous accumulations of cell gases. Fig. 5 (not shown) illustrates a vessel 10 in which high electrolyte level operates a float valve causing gas to enter the vessel and produce electrolyte flow through conduit 9.

Abstract: 1298082 Photographic diffusion transfer process using light absorbing material POLAROID CORP 22 Dec 1969 [23 Dec 1968] 62244/69 Heading G2C A photographic film unit comprises, in order, a photo-sensitive silver halide emulsion, an image-receiving layer in which an image can be formed by diffusion transfer by development by an alkaline processing composition of the silver halide emulsion after exposure thereof, and a transparent support through which an image formed in the image-receiving layer can be viewed, and in which the film unit includes a layer, or means for forming a layer, between the emulsion layer and the image-receiving layer of a light reflecting agent effective to mask the silver halide emulsion when viewing through the transparent support, and in which the film unit includes a layer, or means for forming a layer, between the emulsion and the transparent element that contains a light-absorbing material that during at least the early stages of development will provide a light-absorbing barrier that prevents further exposure of the emulsion through the transparent support when exposed to actinic radiation and that after development will be rendered ineffective as a light-absorbing barrier and will either be colourless or will be immobilized on the silver halide side of the lightreflecting layer. An opaque support layer may be present on the side of the silver halide emulsion distant from the image-receiving layer or else an opaque sheet may be superposed after exposure. The film unit may contain an alkaline processing composition in a rupturable container. The rupturable container may be positioned to discharge its contents between the image-receiving layer and the silver halide emulsion and may contain the light-reflecting material. The light absorbing material may be present in the processing composition or in a transparent layer through which exposure is effected, the layer having an initial pH at which no visible light is absorbed. The light-absorbing material may be rendered colourless after development by change of pH in the unit due to the presence of a layer of acid reacting reagent in the film unit. Alternatively, the light-absorbing material may remain coloured after development and be mordanted to a layer in the film unit on the silver halide side of the light reflecting layer. The light-absorbing material may be an organic dye, e.g. a phthalein dye. The photo-sensitive silver halide emulsion may comprise at least two selectively sensitized silver halide emulsions each having associated therewith a dye image-forming material, e.g. a dye developer. This invention may also be used in the formation of silver transfer images.
