Classes 80 (2) and 80 (4) [Also in Group XXVI] In order to facilitate transport over rough country and erection in the field of a gasturbo-generator installation, three separate bedplates 8, 9, 10 are provided and are bolted together on site, each plate having supporting rollers, which may be retractable, and built-in jacks and spirit levels, the plates 8, 9, 10 having detachably secured thereto an alternator 7 with its exciter, a power-turbine 21 with its reduction gearing 35, and a compressor-turbine unit 11, 12. A duct 18 conveys air from the compressor 11 to an external combustion chamber from which hot gas is conveyed to the turbine 12. Exhaust of the turbine 12 feeds the power-turbine 21 whose rotor 73, Fig. 4b, is connected by a shaft 88 and detachable flexible coupling 89 to the input shaft of the reduction gearing 35. The output shaft 92 of the gearing has a flange to which is attached a spigot 93 carrying a convex spherical-faced ring 95 engaging a corresponding concave ring on the input shaft 96 of the alternator 7. Drive is transmitted by an internally toothed sleeve 97 located by circlips and engaging teeth on the members 93, 96, the spigot 93 thus supporting the alternator rotor, which has a single bearing at its far end. The three bed-plates are coupled together by ears 48 and tapered-shank bolts-there may be one bolt for each ear, giving a vertically-flexible coupling, or two bolts, giving rigid coupling. In a modification, a heat exchanger is connected to the compressor outlet and the combustion chamber and the two turbine units are supported on a single bed-plate-i.e. there are only two bedplates in the installation. Two forms of taper bolt with provision for extraction are described, the one having a tapped recess to receive an extractor bolt while the other has a threaded portion to receive an extractor nut. The axial flow compressor 11 comprises an outer casing carrying stator blading and a rotor which is coupled by a detachable flexible coupling 59, Fig. 4a, to an extension shaft of the rotor 62, 63 of the turbine 12. An annular diffuser 30 of the compressor is continued by a part 51 of the outlet duct 13, this part having integral webs acting as guide vanes. The diffuser 30 and duct 13 are secured to the housing of one of the compressor bearings. The bearing housing 65 of the turbine 12 is secured to an intermediate casing 58 which is supported by a bracket 67 on the plate 10. The casing 14 of the turbine inlet duct is secured to a skirt on the casing 58 and supports the stator casing 75. The bearings for the power turbine 21 are carried by a projection 38, Fig. 4b, of the reduction gearing housing 35, which is bolted on the base-plate 9. It is stated that the power turbine 21 may be omitted and the installation be of the type wherein a single turbine drives both the 'compressor and the generator.

Title: Improvements in the manufacture and production of vat dyestuffs of the benzanthrone series
IPC: C09B5/40
Filed: 1929-10-04
Abstract: Benzanthrone derivatives.-2- benzanthronyl - 1 - aminoanthraquinones containing at least one aliphatic acylamino group in the anthraquinone residue and having the 2-position free, are treated with acid condensing agents to give analogous carbazolized products to those of the parent Specification.  The acylamino group in these products or the aroylamino group in the products of the parent Specification may be saponified, and the resulting amino derivatives treated with acylating agents, or condensed with vat dyestuffs containing halogen, or diazotized and subjected to a Sandmeyer reaction.  As acid condensing agents in the first process may be used concentrated or fuming sulphuric acid, chlorsulphonic acid, and anhydrous aluminium chloride and in some cases the preparation of initial materials and the subsequent acid condensation may be carried out in one operation. In examples (1) 21-benzanthronyl-1-amino-4-acetylaminoanthraquinone (prepared by condensing 2-chlorbenzanthrone with 1-amino-4-acetylaminoanthraquinone) is treated with chlorsulphonic acid or monohydrate or fuming sulphuric acid; (2) mono - 21 - benzanthronyl - 1.4 - diamino-anthraquinone is heated with a mixture of aluminium chloride, trichlorbenzene and acetic anhydride; the product dyes yellowish-green shades: (3) 21-benzanthronyl - 1 - amino - 4 - benzoylaminoanthraquinone is treated with a mixture of chlorsulphonic acid and sulphuric acid, diluted, and warmed, to yield a product containing no benzoyl radicle and dyeing dark green shades: similar treatment of the product prepared from 2.6-dichlorbenzanthrone (1 mol.) and 1-amino-5-benzoylaminoanthraquinone (1 mol.) yields a saponified derivative giving blue-grey dyeings.  Other acyl radicles may be introduced into the amino groups of these derivatives, such as those of halogen- or nitro-benzoic acids, anthraquinone carboxylic acids, oxalic acid, succinic acid, iso- and terephthalic acids: (4) the saponified product from 21-benzanthronyl - 1 - amino - 4 - benzoylaminoanthraquinone obtained as in (3) is diazotized and boiled in alcohol to give a green dyeing product; the diazo group may also be replaced by other substitutents, such as halogen, cyanogen, hydroxyl or mercapto groups, which latter may also be etherified. Specification 273,656, [Class 2 (iii), Dyes &c.], also is referred to.
