Patent GB-1045242-A (GB)
Title: Diazonium compounds and diazotype material
IPC: C07D307/68
Filed: 1964-01-21
Abstract: The invention comprises a diazonium compound of the general formula <FORM:1045242/C2/1> in which X is an anion, R1 is an alkyl, branched alkyl, cycloalkyl or aralkyl radical, R2 represents hydrogen or an alkyl, branched alkyl, cycloalkyl, aralkyl, aryl or heterocyclic radical, or an alkoxy, branched alkoxy, cycloalkyloxy, aralkyloxy, aryloxy or a hetercyclic radical, which is attached to the CO-group via an oxygen atom, or represents a substituted amino group or a substituted amidocarbonyl or a substituted amidocarbonylalkyl group, R3 is an alkylsulphonamido, aralkylsulphonamido, arylsulphonamido, 2 - amino - 4 - imino - 1,3,5-triazinyl (1)-group or a -NH-CO-R5-group in which R5 represents hydrogen or an alkyl, branched alkyl, cycloalkyl, aralkyl, aryl or heterocyclic radical, or an alkoxy, branched alkoxy, cycloalkoxy, aralkoxy, aryloxy radical or a heterocyclic radical which is attached to the CO-group via an oxygen atom, or represents a substituted amino radical or a substituted amidocarbonyl group, or a substituted amidocarbonylalkyl group, and R4 is an alkyl, branched alkyl, cycloalkyl, aralkyl or aryl radical. The novel diazonium compounds may be made from a 4-chloro-2-aminophenolalkyl, branched alkyl, cycloalkyl, aralkyl or aryl ether whereby the amino group is (a) acylated with, e.g., a carbohalide or an ester of chloroformic acid, or (b) converted into a sulphonamido group using an organic sulphochloride, or (c) reacted with dicyandiamide to form a bi-guanidino group, whereupon ring closure to form a triazinyl ring with an organic carboxylic acid or its anhydride takes place.  The ether or 4-chloro-2-(acylamino, sulphonamido or triazinyl) phenol so formed is nitrated and its chlorine atom is then replaced by a monoalkyl, branched alkyl, cycloalkyl, or aralkylamino group, which is subsequently acylated. The nitro group in the product is reduced to the corresponding amine and the diazonium compound is made in the usual way.  The 4-chloro-2-amino-phenol ethers can be made by introducing a nitro group in the ortho position of 4-chlorophenol, etherifying the hydroxyl group and reducing the nitro group to an amino group. The aryl ethers are obtained by fusing 2,5-dichloronitrobenzene with a hydroxyaryl compound and potassium hydroxide and reducing the nitro group.

Title: Improvements in the art of protecting and fireproofing wood and other materials
IPC: B27K3/22
Filed: 1919-02-05
Abstract: 144,342. Thompson, W. P., (Arentox Co.). Feb. 5, 1919. Proofing.-Wood, cloth, &c. are fire-proofed and protected against weather conditions. &c. by treatment with a solution resulting from the interaction of a strong solution of a zinc salt, such as the chloride, sulphate, &c., with slight excess of ammonia, with or without addition of ammonium chloride, bromide, iodide, sulphate, &c., the resulting solution being non-mucilaginous and alkaline to phenolphthalein, and containing between 2 and 10 per cent of combined zinc. For example, 20 kg. of ammonium chloride are dissolved in 300 litres of zinc chloride solution of 50 per cent strength, and to the mixture are added gradually and with constant stirring 350 litres of ammonia solution of 28 per cent strength. Enough water is added to make about 1000 litres of the solution, and the stirring is continued until the temperature developed by the reaction falls to 30‹ C. The solution may be applied to wood, fabrics, &c. by dipping, spraying, &c., but most effectively for fire-proofing wood by the vacuum and pressure treatment. When the treated material is dried, which may be hastened by application of heat, the zinc is deposited as oxide or oxysalts. Reference has been directed by the Comptroller to Specification 42/77.

Abstract: 753,562. Electron lenses. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 7, 1952 [Feb. 10, 1951], No. 3254/52. Class 39 (1). A transverse-field magnetic lens exhibiting focusing in both the axial and radial directions comprises two polepieces forming sectors not greater than 270 degrees of surfaces of revolution, one polepiece having a profile which is parabolic and the other being the equatorial plane or the mirror image of the first polepiece in that plane, and the mean angle between a tangent and the plane being less than 15 degrees; the parabola may be replaced by a tangent or any closer approximation. As shown, the polepieces 5, 7, Fig. 3, have parabolic profiles 8, 9, the parabola being centred at the axis 6 and the tangents 16, 17 at points opposite the principal ray 12 intercepting on the axis a distance b which is half the pole separation a. The angle #, Fig. 2, is preferably between 120 and 135 degrees, the maximum power being attained at an angle of 127 degrees; Fig. 2 shows the shift of focus as the electron velocity varies. An electron microscope in which this chromatic aberration is compensated employs two successive sectoral lenses 26, 30, Fig. 4, of magnification 7 and an electron mirror formed by gun anode 24 of magnification 100, thus giving a final image at 33 of magnification 5000. It is shown that chromate aberration is eliminated if the relation R2(1+V2)=R1V2(1+V1) is observed between the radii of the rays R1, R2 and the magnifications V1, V2 in the first and second lenses respectively. The polepieces may be permanent magnets.
