Patent GB-304743-A (GB)
IPC: C10B3/02
Filed: 1928-03-26
Abstract: 304,743. Koppers Co., (Assignees of Ackeren, J. van). Jan. 26, 1928, [Convention date]. Coke ovens.-In a coke oven battery each heating-wall contains two superposed groups of flues, which are connected in series with corresponding groups in an adjacent heating-wall. The two groups of flues 29, 30, open at their ends into header flues 36, 31, 39, 44, of which the two intermediate ones 31, 39 are connected to pairs of regenerator chambers 32, 33, and 40, 41 at opposite sides of the bench, while the upper and lower header flues 44, 36 are connected by end ducts 45, 37 to corresponding flues of the next heating-wall. The method of operation is such that air or gas is supplied through the regenerator chambers at one side of the bench, while the waste gases are exhausted through those at the other side. Assuming that air and gas are being supplied through the chambers 41, 40, respectively, combustion will be effected in the flues 30 of one heating-wall, and the products will pass through ducts 45 and the corresponding group of flues in the next heating-wall to the regenerators 32, 33. At the same time gas and air are being supplied to the lower group of flues in the second wall and the products from these flues pass through the side ducts 37 and the flues 29 to the regenerators 32, 33. By this arrangement, the heating-gases flow in the same direction through both sets of flues in each heating-wall, and the air and gas to be heated flow vertically upwards through the regenerators, and the waste gases vertically downwards. The ovens may be fired by rich gas supplied through nozzles 49, and in this case all the regenerator chambers are used for heating air. The nozzles 49 pass through partitions 47 in the header flues 36, 44. Each regenerator unit comprises two pairs of chambers, as shown in Fig. 3, and the supply ducts 42, 43 are branched so that each communicates with the two adjacent chambers supplying the same medium. Expansion joints 51 are provided between adjacent regenerator units, and these extend through to the end walls of the ovens.

Title: Process for the production of anhydrous calcium sulphate and plasters made therefrom
IPC: C04B11/05
Filed: 1935-03-25
Abstract: Anhydrous calcium sulphate is obtained by heating a calcium sulphate-calcium sulphite sludge in an oxidizing atmosphere to a temperature of between 900 and 1000 DEG  C.  The sludge is obtained in the removal of sulphur dioxide from flue gases by treatment thereof with an aqueous suspension containing lime or calcium carbonate.  The calcium sulphate produced is suitable for the manufacture of plasters of the accelerated anhydrite type such as are described in Specifications 236,695 and 317,672, [both in Class 22], wherein the setting properties are due to the hydration of anhydrous calcium sulphate under the influence of accelerators such as alkali metal salts and certain sulphates.  In an example, the slurry is passed through a rotary kiln in countercurrent to combustion gases from a furnace burning powdered fuel with excess of air.  The product is mixed with 2 per cent of potassium p  sulphate and 1 per cent of zinc sulphate.  Characteristics of the resultant plaster are given.

Title: Non-woven fabrics
IPC: D04H1/435
Filed: 1974-03-01
Abstract: 1498037 Zone-bonded non-woven interlining BONDINA Ltd 28 Feb 1975 [1 March 1974] 9438/74 Heading D1R [Also in Divisions A3 and B2] An interlining material comprises a non- woven web bonded by a binder in which the area of the web comprises first zones, each of which is at least 5cm in width and has substantially uniform non-zero binder content, and in which adjacent first zones have different binders and/or different binder content and merge into each other over an area which is at least 5mm in width. Preferably different binder formulations 1, Fig. I are applied by doctoring or spraying a continuous web 2 so that each zone runs the length of the web. Support roll 3 may be replaced by a belt. In the embodiment of Fig. 3 baffles 7a, 7b delineate the 3 binder pools 5a, 5b, 5c at the doctor station. The binders for pools 5a, 5c are supplied by traversing pipes 12, 13. Central pool 5b is fed by both pipes and rendered homogeneous by mixer 11. The continuous length of fabric of Fig. 6 is produced using 4 baffles (7, Fig. 5, not shown) to delineate the binder pools corresponding to zones 16-20. The central zone 18 is impregnated with a more concentrated dispersion of a less flexible binder than zones 16 and 20, both binders being polyacrylates. Foamed or viscous aqueous binder compositions are used. to limit the movement of. binder between zones. The different binder compositions may be differently coloured. A uniform application of adhesive may be made before or after the web is zone bonded. The web may be supplied with a discontinuous coating of thermoplastic adhesive by spraying scattering or printing. Some zones may have more adhesive than others.  Preferably the web comprises second zones, each of which has substantially uniform fibre content, -adjacent zones having different fibre contents and merging into one another, as described and claimed in Specification 9439/74. The second and first zones may coincide. In the example a 160 cm wide web is carded and cross-lapped from a mixture of 60% 3.3 dtex, 51 mm long nylon fibres, 20% 8.9 dtex, 60 mm long acrylic fibres and 20% 5.5 dtex 50 mm long polyester fibres, an 85 cm wide web of 22 dtex. 83 mm long nylon fibres is deposited on the centre of  the 160 cm wide web, the composite web passed through a garnett which renders each zone homogeneous throughout its thickness and brings about some merging of the fibres of the three zones. The web is then treated with binder compositions as described above to give the web of Fig. 6. Alternatively the web may be laid and/or rendered homogeneous in its thickness direction by air-laying. The fibres may include sheath-core fibres in at least one zone and the web heated to produce autogeneous bonding. The web may be needled. Alternative binders are those disclosed in U.K. Specifications 898432 and 728865, viz natural rubber, synthetic rubber (butadiene/acrylonitrile copolymer, butadiene/ styrene copolymer and chloroprene) polyvinyl chloride, polystyrene, polymethylmethacrylate, polyacrylate ester and ethylene/vinylidene chloride copolymer.

Abstract: 904,458. Magnetic structures. FUJI SHASHIN FILM KABUSHIKI KAISHA. March 19, 1959, No. 9614/59. Class 38 (2). A magnetic recording tape comprises a layer of flat non-acicular iron oxide particles 4 in a lacquer disposed on a support 6, the planes of the particles being parallel to the support, and the particles being randomly disposed so that equal properties obtain both along and across the tape. In one method, an aqueous solution of ferrous sulphate is added to a caustic alkali in N 2  and ferrous hydroxide is precipitated which is heated for 5 hours at 80‹ C. in N 2  to give flat particles. 1 Á x 1 Á x 0.1 Á in size. These are heated to form γFe 2 O 3  particles which are incorporated in a lacquer and applied to the support. Alternatively, the ferrous hydroxide is converted to α-iron oxide which is reduced to γFe 2 O 3  in H 2  at 350‹ C. In another method, a solution of ferrous sulphate is electrolysed and flat iron particles are scraped from the electrodes. These are heated at 300‹ C. in H 2  and steam to form magnetite which is incorporated into a lacquer, applied to a support and dried in a magnetic field.
