Title: Improvements in the manufacture and production of n-substitution products of 1.4-diamino-anthraquinones
IPC: C09B1/515
Filed: 1934-09-15
Abstract: 1 : 4 diaminoanthraquinones in which the 1- and 4- groups may be substituted by alkyl, arylkyl, cycloalkyl or aryl or heterocyclic groups are obtained by condensing leuco-1 : 4 diamino-, 1 : 4 : 5-triamino- or 1 : 4 : 5 : 8 tetramino-anthraquinones in the absence of reducing agents, with at least 2 molecular proportions of a primary amine free from salt-forming groups, or with at least one molecular proportion of each of more than one different such amine. The condensation takes place at atmospheric pressure, if desired, in presence of a diluent, and if in presence of air to give the substituted amino derivatives, and, if not, give the leuco compound, which may be oxidized with air, oxygen iron chloride or hydrogen peroxide and in presence of copper, to give the amino derivative. When two different amines are employed, uniform products differently substituted in the 1- and 4- positions are obtained.  The products are suitable for dyeing cellulose esters, artificial compositions, lacquers, oils, waxes and petroleum fractions.  According to examples, leuco 1 : 4-diaminoanthraquinone is condensed with butylamine, cyclohexylamine, aniline, ethanolamine and benzylamine; other amines specified are methylamine, propylamine, dodecylamine, ethylene diamine, chloranilines, aminonaphthalenes, phenylene diamines, aminopyridines aminonaphthoquinolines and their derivatives.  Some of the products may be sulphonated for wool dyes. Specifications 26182/03, [Class 2], and 423,256. are referred to. Samples have been furnished under Sect. 2 (5) of products obtainable by treating: (1) leuco-1 : 4-diaminoanthraquinone in accordance with the invention with the following pairs of different amines:--methylamine, and with ethylamine, n-propylamine, n - butylamine, ethanolamine, benzylamine, cyclohexylamine, p - toludine - 1 - aminocarbazol, o-anisidine, p-amino-phenol, aniline, or 4 - amino - diphenylamine, ethylamine with n - butylamine, ethanolamine, or 1 : 2 - propanolamine, ethanolamine with propylamine, n-butylamine, 1 : 2-propanolamine 1 : 3-propanolamine, b -phenylethylamine, or cyclohexylamine, 1 : 2-propanolamine with 1 : 3-propanolamine, benzylamine or b -phenylethylamine or n-propylamine; (2) leuco-1 : 4 : 5 : 8-tetraminoanthraquinone with methylamine and ethanolamine; (3) leuco-1 : 4 : 5-triaminoanthraquinone with the same 2 amines.  The Specification as open to inspection under Sect. 91 includes also as suitable amines, the aniline carboxylic acids, esters and sulphonic acids, toluidine sulphonic acids and aminopiperidines, and the reaction between a leuco-1-amino-4-hydroxy-anthraquinone, and primary amines, in general.

Title: Improvements relating to the welding of metallic parts
IPC: B23K35/02
Filed: 1952-11-05
Abstract: A composition for use as a backing or shielding material in welding metals comprises a solution of silicone putty in a solvent preferably having dispersed therein powdered tantalum hydride. The putty protects the metal from oxidation, the residue being readily removed after welding, and the tantalum hydride, if used, decomposes on welding and provides a reducing atmosphere.  Since water has a marked effect on the viscosity of the putty solution the quantity of water present must be below 0.2 per cent of the composition.  Specified compositions are silicone putty 28-32 grams, tantalum hydride 11-13 grams, xylene 70-80 millilitres. The ingredients are dried before mixing.  A specified silicone putty composition is silicone gum 100 parts; lithopone 15 parts, glycerol 2 parts, pentaerythritol 1 part, ferric stearate 2 parts, red iron oxide (colour).  The silicone gum is prepared by heating at 150 DEG  C. for a total of 25 hours a dimethyl silicone oil with 7 per cent of partially dehydrated boric acid (obtained by heating boric acid at 150 DEG  C. for one hour) and 0.1 per cent of ferric chloride hexhydrate.

Abstract: 248,324. Geisler, O. March 2, 1925, [Convention date]. Balancing.-An airship is maintained on an even keel fore and aft by means of water ballast which is transferred between forward and rear tanks by compressed air under the control of valves actuated by electromagnets in circuit with a mercury level, manual means also being provided for actuating the electromagnets. The Figure shows one of a series of forward tanks 4a and one of a corresponding series of rear tanks 4<b> arranged along the keel of the airship and connected by a common conduit. A port 13 communicating with the interior of a valve casing 8 is provided in each tank above the water level, the valve casing also having an exhaust port 14 and a port 15 communicating with a compressed air tank 6 supplied from a compressor 7. Two plungers 10, 11 connected by a rod 12 are provided in each valve casing and are normally pressed to the left by a spring 40 to uncover the port 14 and close the port 15. A tube 23 containing mercury 24 is, permanently mounted parallel to the keel of the airship, but is shown tilted to illustrate the effect of an upward tilt of the front end of the airship. Under these circumstances a circuit is completed between a plate 25 and a contact 27 and a series of solenoids 20 associated with the tanks 4a and a series of solenoids 19 associated with the tanks 4b are energized and corresponding valves 17, 16 are opened to admit compressed air from conduits 18 to the ends of the valve casings so as to maintain the plungers associated with the tanks 4a in the position shown to the left of the Figure and to move those associated with the tanks 4b to the position shown in dotted lines. Compressed air can then enter the tanks 4b to displace water into the tanks 4a, the air spaces of which are open to exhaust. For an opposite tilt of the airship a circuit is completed between the plate 25 and a contact 26, and the valves 16 of the tanks 4a and the valves 17 of the tanks 4b are opened. A switch 37 in the control cabin of the airship at the forward part of the vessel enables the pilot to bridge the contact 25 and the respective contacts 26, 27 to control the trim of the airship manually. Manually actuated valves are provided at the base of each tank to enable them to be emptied in an emergency.
