Title: Improvements in and relating to gas producers
IPC: C10J3/66
Filed: 1941-01-19
Abstract: 579,967. Gas-producers. BAILEY, R. W., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Jan. 19, 1941, No. 17883/40. [Class 55 (i)] The tar-laden gases from the upper or distillation zone of a gas-producer are led off and introduced into the hot zone so that the tarry products are cracked and pass to the main gas outlet, the point or points of introduction of the tar-laden gases being continuously or intermittently changed, so as to prevent undue cooling of the hot zone. The fuel bed is enclosed by a water jacket having outer and inner walls 2, 3, tubes 4, and 5 carrying the hot gases from a collecting space 3b to an annular chamber 6 and outlet 7. The tar-laden distillates pass into an annular space 8 and are drawn through a port 30 and forced by an injector 32 through a port 28 in a central shaft into the hot zone 33 to which air and steam are also admitted from below through an inlet 19. Air and steam also pass from an inlet 31 through the central shaft and into the hot zone through a port 29, together with steam through pipe 39. The central shaft is enclosed in a water jacket 21, 22, supplied from a pipe 24, and the nozzle 32 is fed with steam and air from pipes 36, 37. The conduit enclosed by walls 21, 22 is fixed to the grate 17 and continuously rotates so that the points of entry of the air, steam, and gases to the hot zone are continuously varied. The steam from the outer jacket may be used for the injector or for any desired purpose, and superheater tubes 13 are arranged in the outlet tube 5. In a modification, a plurality of conduits may be arranged to take the gas from above the fuel bed, each having its own delivery port to the hot zone, and being operated at intervals so as to change the path of the tar-laden gas through the hot zone, and the valve gear for doing this may be operated from the rotating grate.

Title: Improvements in and relating to magnesia and products obtained therefrom
Filed: 1944-09-19
Abstract: Artificial magnesium hydrate is treated to produce a refractory material of increased bulk specific gravity by mixing the finely-divided magnesium hydrate with 2-7 per cent. preferably 3-6 per cent. of lime and 1-10 per cent., preferably 2-6 per cent. of ferric oxide, agglomerating with 15-45 per cent. of water under pressure dependent on the amount of water, and calcining above 1300 DEG C.  The artificial magnesium hydrate prepared, for example, from seawater is mixed with sufficient burnt or slaked lime or dolomitic lime, limestone, dolomite, tricalcium phosphate, or apatite, to bring the calcium oxide content to approximately 4 per cent,, and with iron ore, chrome iron ore or millscale to bring the ferric oxide content to approximately 3 per cent.  A small amount of kaolin or pyrophyllite or a mixture thereof and mineralizers or fluxes may also be added.  The additions are preferably made to a slurry of the magnesium hydrate, and after thorough mixing, the mixture is filtered and the cake is agglomerated at a pressure of at least 500 lbs., and preferably 1500-3000 lbs. per square inch.  The moisture content is such that at the agglomerating pressure moisture just begins to exude from the mass.  Preferably the filter cake is dried at 200 DEG C. and subsequently moistened to the required degree with water, a solution of a magnesium salt, or magnesium hydrate containing a known amount of water.  After drying, the mass is calcined at approximately 1400 DEG C. for 1 hour.  In a modification, the cake may be agglomerated by extrusion, and before final shaping it is subjected to a vacuum to improve its physical properties.  The resultant material is ground and used in the normal manner as a basis for the manufacture of magnesia or chrome-magnesia bricks.

Title: Manufacture of anthraquinone vat dyestuffs
IPC: C09B1/42
Filed: 1951-07-30
Abstract: The invention comprises 1-acylamino-6-fluoro-anthraquinones, wherein the acyl radical is that of a diphenyl or substituted diphenyl carboxylic acid.  They are made by (1) condensing 1-amino-6-fluoro-anthraquinone with the halide of a diphenyl monocarboxylic acid; or (2) condensing 1 - chloro - 6 - fluoro - anthraqunione with the amide of a diphenyl monocarboxylic acid.  The fluoro-anthraquinones referred to may be made by the process of Specifications 712,837 and 712,889, [Group IV (b)], and may be mixed with the corresponding 1,7-isomers.  The products may be used as pigment dyestuffs or for dyeing or printing linen, cotton, artificial silk, or viscose greenish-yellow shades.  They may be used in the form of their leuco-sulphuric ester salts.  In examples: (1) 1-amino-6-fluoranthraquinone is condensed with diphenyl-4-carboxylic acid chloride or its 41-chloro- or 41-methylsulphone derivatives; and (2) 1-chloro-6-fluoranthraquinone is condensed with diphenyl-4-carboxylic acid amide.  A dyeing example is given.  The diphenyl residue may also contain alkyl, e.g. methyl, groups.ALSO:The 41-sulphinic acid of diphenyl-4-carboxylic acid is prepared by reaction of diphenyl-4-carboxylic acid with chlorosulphonic acid and reduction of the reaction product with sodium sulphite to give the 41-sulphinic acid, which is salted out as its sodium salt. p 41-Methylsulphone-diphenyl-4-carboxylic acid is obtained from the above sulphinic acid by reaction with methyl iodide in aqueous alcohol.

Abstract: 1,008,985. Photo-electric control of cameras. OPRISCHE INDUSTRIE "DE OUDE DELFT". N.V. May 9, 1963 [May 10, 1962], No. 18463/63. Heading G2A. In a camera having a focal plane shutter, the shutter has a diffusely reflective surface, e.g. white paint, so that light is reflected from it to a photoelectric cell placed out of the direct light path through the objective, the cell then controlling the diaphragm. In the form shown, the shutter comprises two coaxial discs 8, 9, each having one or more exposure slots (although a roller blind shutter may be used). Disc 8 is driven, and drives disc 9 through gear wheels to give a differential speed ratio. When the slots coincide in front of windows 6, 7 in the housing walls an exposure is made on the film in cassette 10. Disposed out of the direct light path through objective 3 to the film is a photoelectric cell 29, which can receive light reflected from the white-painted surface of shutter disc 9. The signal from cell 29 can be compared with a reference signal, and the difference, if any, used to control a motor 28 which drives, through gears 27, 26, 25, a dial ring 21 adjusting the aperture of objective 3. Thus there is provided an automatic exposure control ensuring a fixed average illumination of the focal plane, which can also be adapted to take film sensitivity into account. The signal from the cell may be given an A.C. component by providing the shutter disc with alternating white and black sectors.

[Also in Groups XXV and XXXVI] In the device described in the parent Specification for supporting pipes connected to machine parts movable on guides or tracks and comprising a chain which receives and externally protects the pipes and the links of which can only swing through a limited angle relative to one another, the chain is movable over two, parallel, guide tracks the centre line distance apart of which corresponds to the smallest diameter of curvature of the chain. As shown, the chain is formed of chain plates 1, 2 connected together by pins 3 and provided with sloping and straight edges 4, 5, the web members 6 between the plates having bores or slots 7 for reception of the pipes ; axles 8 for rollers 9, 9a pass through the webs of some of the chain links, and the rollers are supported on raised guide tracks 13, 14 on a base-plate 15 forming part of a U-shaped casing 16 in which the chain. is movable. The free end 10 of the chain is connected to a fixed connection box or a takeoff arm 11 and the free end of the chain 12 is secured to the machine part. Bowing of the length of chain 10, when pushed in the opposite direction to the arrow shown in Fig. 2, or abrasion of the wall of the casing by the rollers 9a, is avoided by providing the track 13 with a guide edge or strip 18. Movement of the chain is produced or assisted by one or more motors. In modifications, a guide strip or track curved in a vertical plane continues from the track 14 so that the machine part can move in a vertical plane as well as a horizontal plane, the edges of the chain are sloped to allow the chain to be curved in both directions, and single rollers on the outside of the chain are used ; alternatively, the chain is supported by balls running in corresponding formations in the tracks 13, 14.
