Title: Process for the manufacture of tris- and tetrakis-azodyestuffs
IPC: C09B35/46
Filed: 1935-02-25
Abstract: Tris- and tetrakisazo dyes are made by combining, in an alkaline medium, the diazoazo compound formed in an acid medium from 1 mol. of a 4 : 4<1>-tetrazodiphenyl and 1 mol. of a periaminonaphthol sulphonic acid with a monodiazo or diazoazo compound and finally coupling with a m-phenylene diamine having one of the amino groups acylated other than by a sulphonyl group and the hydrogen atoms of the other amino group entirely or partly replaced by unsubstituted or substituted alkyl, aralkyl or aryl groups.  The process may be modified by combining in an alkaline medium the azo compounds obtainable by coupling, in an acid medium, one mol. of a monodiazo compound of the benzene series containing a substituent convertible into the amino group, with one mol. of a periaminonaphthol sulphonic acid, with a monodiazo or diazoazo compound, converting the specified group into the amino group, diazotizing, and finally coupling with the m-phenylene diamine derivative.  They yield black shades on cellulose fibres and leather fast to acids.  In examples, dyes are described from the following components: benzidine and its 2 : 2<1>disulphonic, 3 : 3<1>-dichloro- and 3 : 3<1>-dicarboxy derivatives, p-nitroaniline; H and K acids; p-sulphanilic acid, aniline, o-, m-, or p-aminobenzoic acid, 4-aminoazobenzene-4<1>-sulphonic acid, p-nitroaniline, naphthionic acid, a -naphthylamine, aminoazobenzene sulphonic acids; diethyl-m-aminoacetanilide, 1-methyl-2-dimethylamino - 4 - acetylaminobenzene, m-benzoylaminodimethylaniline, monohydroxyethylamino-, dihydroxyalkylamino- or hydroxyalkylalkylamino-m-acetanilides; oxalyl and phthaloyl compounds are also mentioned.

Patent GB-416007-A (GB)
Title: Improvements in or relating to the manufacture of cyanhydrins
Filed: 1933-03-01
Abstract: Ketone cyanhydrins of the aliphatic series are manufactured by adding to an aliphatic ketone, maintained at boiling point and containing a base dissolved therein, an equimolecular proportion of hydrocyanic acid in the gaseous or, preferably, in the liquid state.  Suitable bases are: alcoholic or aqueous caustic soda, gaseous or aqueous ammonia, pyridine, piperidine, quinoline, primary, secondary or tertiary amines, potassium or sodium cyanide.  The cyanhydrin is recovered by acidification, preferably with a non-volatile mineral acid, e.g. sulphuric acid, which may be in 50 per cent excess over the base present, followed by distillation under reduced pressure. The cyanhydrins may be converted into unsaturated nitriles of homologues of acrylic acid by dehydration with a powerful dehydrating agent, e.g. phosphorus pentoxide, in the presence of a soluble base, preferably in the presence of a diluent, e.g. tetrahydronaphthalene, which may be added before or after the dehydrating agent.  The dehydrating agent may be added to the mixture of cyanhydrin and base with efficient cooling, or the dehydrating agent may be added first followed by the base.  In examples: (1) liquid hydrocyanic acid is added to a boiling solution of piperidine in acetone and the acetone cyanhydrin is isolated and converted to methacrylonitrile by adding quinoline followed by phosphorus pentoxide, if desired with the addition of a diluent, e.g. tetrahydronaphthalene; (2) hydrocyanic acid is added to a boiling solution of pyridine in acetone and the reaction mixture is cooled and worked up for the production of methacrylonitrile by the addition of pyridine followed by gradual addition of phosphorus pentoxide and then of more pyridine, or by the addition first of the phosphorus pentoxide and then of the pyridine.

Abstract: The invention comprises pyrazolo-benzimidazoles of the formula <FORM:1047612/C2/1> which are substituted in the 2-position by a C1- 20 alkyl, aryl, carboxyl, carboalkoxy, carbonamido, or substituted carbonamido group, in the 3-position by a halogen atom or a sulphonic acid group, and in the 7-position by a halogen atom or an alkoxy, carbonamido, substituted carbonamido, carboxyl or carboalkoxy group with 1-18 carbon atoms in the alkyl moiety. The compounds may be further substituted in the 5,6 and/or 8-positions by, e.g. sulphonic acid, sulphonamido, carboxyl, carboalkoxy or carbonamide groups, or halogen atoms.  The compounds are made by intramolecular dehydration of 1 - (o  - amino - phenyl) - pyrazol-5-one or by deamination of 1-(o -amino-phenyl)-5-amino pyrazoles.  The substituent in the 7-position is introduced before cyclization and the substituent in the 3-position introduced by chlorination or sulphonation after cyclization. The compounds are used as photographic colour-couplers. Examples are provided.  The 1 - (o  - amino - phenyl) - pyrazol - 5 - one reactants are made by reducing o -dinitrobenzene to the o -nitro-phenylhydrazine, condensing the latter with a b -keto-ester to form a 1-(o -nitro-phenyl)-pyrazol-5-one which is subsequently reduced to the corresponding amino compound.

Title: Improvements in or relating to surveying instruments
IPC: G01C17/12
Filed: 1920-03-06
Abstract: 165,915. Shaw, J. P. March 6, 1920. Theodolites; angle-measuring instruments.-Relates to instruments for the measurements of angles and distances, of the kind comprising a telescope with an extension at right-angles to its axis, this extension having at its outer end a reflector attached to a pivoted lath &c., which reflector co-operates with a fixed reflector within the telescope to produce an image which can be brought into coincidence with a .direct image by turning the lath. The invention consists in the manner of graduating the circles &c. and in the general construction of the instrument. As shown in Figs. 1 and 2, each of the circles of the instrument carries two concentric scales, of equal width, the outer scale E being a scale of tangents whilst the inner scale F is divided equiangularly. Only one quadrant is shown in the Figure. To facilitate the reading by means of a micrometer of fractions of the smaller divisions on the scales, the actual scale markings consist of the diagonal lines connecting opposite ends of successive divisions as shown in Fig. 2. The distance to be subdivided by the micrometer is then the constant width of the scales. The micrometer comprises a microscope - 5 with pointers 6, Fig. 3, mounted so as to be traversed radially across the scales by a differential screw 8, 9 having an evenly divided head 10. The microscope is moved until the pointer intersects the diagonal graduation line on the scale, the traverse for a complete turn of the head 10 being equal to the radial width of the scales. The instrument comprises a telescope 21, Figs. 5 and 7, rotatable in altitude and azimuth and having at right angles to its axis a rigid tube 24 carrying at its outer end H a reflector 23 attached to a pivoted lath 28. The field of the telescope is partly occupied by a. reflector 25 receiving light directed along the tube 24 by the reflector 23 so that two images of an observed object are seen in the eyepiece 20. These images can be brought into coincidence by turning the lath 28, the angle of rotation being read on scales 29 graduated as above described. For levelling the instrument the horizontal circle 36 carries two diametrically opposite pins 52. One of the pins engages in a bracket 44 pivoted at 43 in a channel iron 42 secured to an arm 48. The bracket carries a toothed sector 45, Fig. 9, which can be rotated by a worm 46. The other pin 52 passes into a block 50, Fig. 8, which is pivoted at 51 in a fork 49 which can be adjusted vertically by a screw 53 bearing in an arm 54. The arms 48, 54 may be integral with a ring 56 which can be clamped to the tripod head by screens 57.
