Title: Improvements in the manufacture and production of azo dyestuffs
IPC: C09B35/46
Filed: 1935-07-08
Abstract: Polyazo dyestuffs are manufactured by coupling the tetrazo compound of a 4 : 4<1>-diaminodiphenyl (or mixture of 4 : 4<1>-diaminodiphenyls) in an acid medium with one molecular proportion of a 1-amino-8-naphtholsulphonic acid capable of coupling twice, and coupling the product in either sequence with a diazo compound of an aromatic amine or aminoazo compound and with a 2 : 4-dihydroxyquinoline or a 4-hydroxyquinolone.  The products dye wool, silk, cotton and mixed fabrics of these fibres, paper and leather, especially velour leather, generally in greenish black shades.  In examples: (1) tetrazotized 4 : 4<1>-diaminodiphenyl is coupled acid with 1 : 8 : 3 : 6-acid and the product is coupled in slightly alkaline solution with diazotized 1 - amino - 2 - nitrobenzene-4-sulphonic acid and in more strongly alkaline solution with 2 : 4-dihydroxyquinoline monosodium salt; the 1-amino-2-nitrobenzene-4-sulphonic acid may be replaced by 4-aminoazobenzene-4<1>-sulphonic acid, 1-aminobenzene-4-sulphonic acid or other amine, preferably one containing a sulphonic or carboxylic group, e.g. an aminonaphthalene sulphonic acid, an aminodiphenylaminesulphonic acid, an aminohydroxybenzenesulphonic acid, an aminohydroxybenzenesulphonic acid or an aminobenzenecarboxylic acid; (2) the 2 : 4-dihydroxyquinoline in (1) is replaced by its sulphonic acid (obtained by sulphonating 2 : 4-dihydroxyquinoline with oleum and probably containing the sulphonic group in the 6- or 7-position); in this case the 1-amino-2-nitrobenzene-4-sulphonic acid may be replaced by an amine free from sulphonic groups, e.g. aniline; the 2 : 4 - dihydroxyquinoline or its sulphonic acid may also be replaced by other derivatives thereof, e.g. N-methyl - 4 - hydroxyquinolone, the 1 : 8 : 3 : 6-acid by 1 : 8 : 4 : 6-acid and the 4 : 4<1>-diaminodiphenyl by its derivatives such as its 3 : 3<1>-dimethyl or 3 : 3<1>-dichloro derivative of its 3 : 3<1>-disulphonic acid; (3) a mixture of tetrazotized 4 : 4<1>-diaminodiphenyl and its 3 : 3<1>-dimethyl derivative (or tetrazotized 4 : 4<1>-diamino - 3 : 3<1> - dimethyldiphenyl alone) is coupled acid with 1 : 8 : 3 : 6-acid and the product is coupled alkaline with diazotized 1-aminobenzene-4-sulphonic acid and with 2 : 4-dihydroxyquinoline; (4) the compound obtained by coupling tetrazotized 4 : 4<1>-diaminodiphenyl with 1 : 8 : 3 : 6-acid is coupled in slightly alkaline solution with diazotized 1-aminobenzene-2 : 4-disulphonic acid and then in strongly alkaline solution with 7 : 8-benzo-2 : 4-dihydroxyquinoline (prepared from 1-aminonaphthalene and maleic acid diethyl ester).

Patent GB-786554-A (GB)
Title: Improvements in or relating to the projection of televised images in colour
IPC: H04N9/16
Filed: 1954-07-02
Abstract: 786,554. Colour television; light modulating. SOC. GENERALE D'ELECTRONIQUE. July 2, 1954 [July 4, 1953], No. 19516/54. Class 40 (3). Relates to an arrangement for the projection of television images wherein light from an external light source 9, Fig. 5, is modulated in accordance with the image detail by means of an optical system comprising grids G1, G2 and a cathode-ray tube incorporating a reflecting surface in the form of a metallic sheet 3 deformable by a scanning electron beam modulated by signals representative of the image. With a flat sheet the spaces between bars in grid G1 are imaged on to the bars of grid G2, so that no light passes, and the act of deforming the sheet is to allow light to pass to form an image in the direction E. In accordance with the invention, the arrangement is adapted for projecting coloured images by inserting a colour splitter, such as a prism 10 or a combination of coloured filters, in the path of the light source and by forming the support for the deformable sheet, which is insulating and light transmissive, with a series corrugations 5 which function as lenses. By this means, the sheet 3, as shown more fully in Fig. 2, may be illuminated for each corrugation with blue, green and red light over separate bands b, r and r. A network of parallel filaments 7 having a pitch three times the pitch of the bands is now disposed between the sheet and the source of electron scanning so that a different direction of approach is required to scan each colour. In one arrangement, three cathode-ray guns may be provided to control the scanning of the three sets of colour bands simultaneously. In another arrangement a single electron gun is employed together with a deflecting coil to change the direction of beam approach to cause the three colours to be scanned in a " spot sequence." The deformable sheet is constructed and supported by means of spacing prism 6 as described in Specification 786,553. Figs. 6 and 7 (not shown) illustrate alternative arrangements for mounting the deformable sheet in which it is carried by a separate thin glass plate lying against a glass plate corrugated either on its inner face or on both faces. In a modified system, the two grids G1 and G2 are replaced by a single striated mirror system inclined at 45 degrees to the axis of the cathode-ray tube. The light source and colour splitter are disposed at right angles to the cathode-ray tube axis and illuminate the deformable sheet by reflection from the striatious. Returned light then passes between the striatious to form the image. Reference is also made (1) to an arrangement employing a light splitter in the form of a double prism so that the bands of coloured light formed on the deformable sheet are in the sequence red, green, blue, blue, green, red, and (2) to an arrangement utilizing a pair of interleaved filament assemblies to which switching signals are applied to direct the scanning beam to the desired coloured band.

Soldering.-In a solder-bath machine for soldering the ends &c. on tins &c., of the kind in which the article is supported on a member, whose upper edge normally projects above the surface of the solder &c. which is free to move up and down so as to immerse the joint in the solder, an adjustable stop is provided so as to limit the downward movement of the member. The work is placed on the top of a hollow member 14 the edge 14<a> of which normally projects above the surface of the solder in a bath 1 mounted in a heat-insulated casing 2 and heated by gas burners 5 &c. The member, which may float in the solder, is free to move in a guide 13 which is carried by an extension 12 from a ring 11 provided with brackets 10 engaging pins 9 secured to lugs in the bath. The ring 11 keeps the scum formed on the top of the solder clear of the member 14. The article when placed on the member is pressed down, so as to immerse the joint in the solder, against a stop member 16 adjustable on lugs 15 on the ring 11. For soldering small articles the guide 13 may be first fitted with a flanged liner to receive a smaller member. In place of a floating member, a member may be used which may be pressed upwardly by springs, weights, or pneumatic pressure. Springs may be arranged either above or below the member, which in the latter case has means project ing through a packing gland on the bath. The weight may be fixed on a lever, and in the pneumatic arrangement the member may be connected with a plunger working in a cylinder so as to compress the air when it is forced down. According to the Provisional Specifications, the stop may consist of an adjustable screw passing through the bottom of the bath. A run-off cock may also be provided for the bath.
