Title: Manufacture of vat-dyestuffs of the anthraquinone series
IPC: C09B5/24
Filed: 1925-09-23
Abstract: 261,510. Bloxam, A. G., (Chemische Fabrik Griesheim-Elektron). Sept. 23, 1925. Anthracene, dyes derived from.-Vat dyes are obtained by condensing arylketodihydrop-thiazines, dihalogenated in the methylene group, with o-diamines or their N-alkyl or N-aryl derivatives. or their nuclear substitution products, at least one of the components being an anthraqninone derivative. The condensation may be effected in an organic solvent with or without a condensing agent such as sodium acetate which absorbs water or acids. The dyes derived from nan-alkylated or non-arylated o-diamines are not fast to alkali but can be made fast by alkylation. the products being probably the same as when alkylated o-diamines are used in the first place. According to exampl.es, condensation products are produced from the following pairs of components :-(1) anthraquinone-dichlorketodihydro-2:1-thiazine and ophenylenediamine or 4 : 5-diamino-1 : 3-xylene or 1 : 2-diaminoanthraquinone. the product from the latter being then ethylated with toluenesulphonic ethyl ester; (2) anthraquinonedichlorketodihydro- 2 : 1-thiazine and 1-amino-2-toluidoanthraqninone; (3) p-tolyrketo-dichlordihydro-p-thiazine and 1 : 2- diaminoanthraquinone. The products are purified by means of hypochlorite solution and dye cotton from the vat in yellow to brown shades. p-Tolylketodihydro-p-thiazine is obtained by condensing p-amino-thio-m-cresol with chloracetic acid. Dihalogen derivatives of arylketodihydro-p thiazines are obtained by halogenating the parent bodies, for example by means of chlorine or sulphuryl chloride in presence of a diluent. 1-Amino-2-toluidoanthraquinone may be made from 1-amino-2-bromanthraquinone and p-tolui. dine.
Patent GB-989373-A (GB)
Title: Improvements in or relating to the treatment of industrial waste gases
IPC: B01D53/68
Filed: 1961-07-03
Abstract: Fluorine, in the form of cryolite, is recovered from a gas mixture comprising volatile fluorine compounds and carbon dioxide gas by washing the degritted gas mixture with an aqueous alkaline solution to remove fluorine compounds soluble in the alkaline solution but leaving substantially all the carbon dioxide in the gas, the solution resulting from the washing having a pH between 4 and 9, substantially eliminating dissolved and combined carbon dioxide from the resulting washing solution to form a decarbonated washing solution, adding sodium aluminate to the decarbonated washing solution to form a sodium aluminate solution, treating the sodium aluminate solution with the washed carbon dioxide containing gas, and recovering the cryolite. Any sulphur contained in the decarbonated solution may, if desired, be removed in conventional manner, e.g. by passing the solution over an anion exchange resin.  The removal of dissolved and combined carbon dioxide from the alkaline washing solution may be achieved by the addition thereto of a solution obtained by washing a portion of the initial gas with water.  After precipitation the cryolite may be filtered from the mother liquor and the mother liquor then used as the alkaline washing solution, further alkali being added if necessary.

Title: Improvements in or relating to endless tread belt links
IPC: E02F9/02
Filed: 1929-08-06
Abstract: 317,082. Bucyrus-Erie Co., (Assignees of Snyder, T. A.). Aug. 11, 1928, [Convention. date]. Endless-track vehicles.-A cast-metal link or shoe for an endless-track is constructed with upstanding ribs or flanges as shown, all upstanding parts being sloped downwardly and outwardly from their summits and the link being coreless, except for hinge-pin and retaining-pin cores, to facilitate casting. In the construction shown the link is of the kind described in Specification 225,606 having a broad tread and a single rollerpath 10 for the load-carrying wheels which run between flanges 11. According to one feature of the present invention the flanges 11 are cut away at 13 to permit the extrusion of dirt from the runway as the wheels pass over it. 'The links are formed with bosses 14 at one end and corresponding recesses 15 at the other end, and are pivoted together by pins 16 which abut against stops 20 cast on the link and are held in place by T-headed pins 22 secured by cotter pins 25. Diverging ribs 26 extend from the bosses 14 to the recesses 15, and these, together with the flanges 11, stops 20 and other projections are made larger at the base than at the top. The faces 12 of the flanges 11 are adapted to be engaged by projections on a driving wheel (not shown). The tread portion of the link is arched under the roller-path 10 so as to avoid too great thickness of the metal in this part. Recesses are formed on the underside of the link to indicate suitable places at which to bore holes for the attachment of cleats for use on slippery ground.

Abstract: 1427221 Two part coupling ERCO-LEUCHTEN GmbH 23 May 1973 24624/73 Heading H2E An overhead connecting and mounting track and adapter for electrical fixtures comprises an elongated metal channel member 9 to be recessed in a ceiling with its open underside exposed, having in its base two conducting contact strips 64 arranged to grip resiliently blade contacts inserted from below. A junction box 11 at one end of the channel, mounted above the ceiling, couples the mains supply, fed through a knock-out 23 to the contact strips 64 running along insulating troughs 57. The lower part of the junction box matches the channel in cross-section, and is coupled to it by side strips in grooves, clamped by pressure from screws tapped into the strips (Fig. 5, not shown). The fused adapter unit 12 (see Fig. 11) mounted on appliance conduit 79 can be inserted at any lengthwise position, with blades 133, 139 engaging the conductor strips. Before the blades engage, grounding contacts 160 touch the channel walls, and on complete insertion latch into place via detents 163 (Fig. 9) behind shoulders 45a. Removal is by displacing finger pieces 165 to free detents. Under hinged cover-plate 122 in insulating body 91 a cartridge fuse completes the circuit between the blades and wires passing up conduit 79, through base-plate 76 and a thin insulating plate, finally being trapped in a shallow cavity in the base of body 91 where they are connected to one blade and to one fuse clip. The body and base-plate and spring metal strips which terminate in finger pieces 165 and ground contacts 160 are all held together by two screws 156.
