Title: Manufacture of azo-dyestuffs
Filed: 1923-12-13
Abstract: Azo dyes are produced by coupling diazo compounds with bis-(2 : 3-oxynaphthoyl)-4 : 41 diamino-3 : 31-dialkyloxydiaryls; the dyestuffs may be produced upon a substratum or upon the fibre, various shades of brown being thereby obtained.  As diazo compounds may be used those of aniline and its substitution products, such as toluidines, anisidines, chlor- and nitro-anilines, chlor- and nitro-toluidine, chlor- and nitro-anisidines, naphthylamines, aminoanthraquinones, aminoazo-compounds, and diamines; nitrosamines may also be used. Prints may be produced by printing with diazo solutions upon goods padded with the 2 : 3-oxynaphthoic acid derivative.  In an example an orange-brown shade is produced on cotton yarn impregnated with bis-(2 : 3-oxynaphthoyl)-dianisidine by developing, without drying, in a solution of diazotized 2 : 5-dichloraniline.  A table is given showing the shades obtainable from bis-(2 : 3-oxynaphthoyl)-dianisidine or bis-(2 : 3-oxynaphthoyl)-diphenetidine on the one hand and the diazo or tetrazo compounds of the following bases:-o-toluidine, m-chloraniline, 2 : 5- or 3 : 5-dichloranaline, 4- or 5-chlor-2-toluidine, 4-chlor-3-toluidine, 4-chlor-2-anisidine, 4- or 5-nitro-2-toluidine, 3-nitro-4-toluidine, 4- or 5-nitro-2-anisidine, 5-nitro-3-anisidine, 4- or 5-chlor-2-nitraniline, 2- or 3-chlor-4-nitraniline, 3 : 5-dinitraniline, 4-nitro-anthranilic acid methyl ester, 5-nitro-3-aminobenzoic acid ethyl ester, a -aminoanthraquinone, m-aminoazotoluene, benzidine, dianisidine. Bis-(2 : 3-oxynaphthoyl)-4 : 41-diamino-3 : 31-dialkyloxy-diaryls are obtained by the action of 2 : 3-oxynaphthoic acid on 4 : 41 diamino-3 : 31-dialkyloxydiaryls; the properties of the compounds from dianisidine and diphenetidine are given.ALSO:Fast brown shades are produced upon the fibre by impregnating with a bis-(2 : 3-oxynaphthoyl)-4 : 41-diamino-diaryl and developing with a diazo compound; the latter may be applied by printing.  As diazo compounds may be used those of aniline and its substitution products, such as toludines, anisidines, chlor- and nitro-anilines, chlor- and nitro-toluidines, chlor- and nitroanisidines, naphthylamines, aminoanthraquinones, aminoazo compounds, and diamines; nitrosamines may also be used.

Filed: 1963-08-08
Abstract: A process for the production of fire resistant rigid polyurethane foams comprises reacting the unpurified product, containing from 40 to 90% by weight of volatile aromatic diisocyanate, from the phosgenation of an aromatic diamine, with a polyol and a fire retardant agent, in the presence of a blowing agent, using at least one equivalent of isocyanate group per equivalent of active hydrogen. Preferred volatile aromatic diisocyanate components are the products of phosgenation of a tolylene diamine and p,p1 diaminodiphenylmethane, but suitable alternatives are meta- and paraphenylene diisocyanate chlorophenylene diisocyanate 1.5. napththalene diisocyanate and 3,31 - dimethyl - 4,41 - diphenylmethane diisocyanate, from the phosgenation of the corresponding amines.  The product of the phosgenation may be used by itself or blended with one or more volatile aromatic diisocyanates from a separate source.  The polyols specified are poly-functional polyesters, hydroxyl-ended polyesteramides and polyethers containing a plurality of hydroxyl groups.  The fire retardant agents specified are those containing halogen and/or phosphorus such as diallyl styrene phosphonate, diallyl phenyl phosphonate, tetrachlorophthallic acid, dibromophthallic acid, dibromosuccinic acid, tri-(2,3-dibromopropyl) phosphate; tris-(2,3-dichloropropyl) - phosphate, tris - (chloroethyl) phosphate; bis - b  - chloroethylvinyl phosphonate, a phosphorus-containing diol, and chlorinated naphthene.  Preferred fire-retardant agents are polyfunctional polyethers which contain halogen and/or phosphorus as an integral part of the polyether molecule, e.g. the products of epichlorohydrin and glycerin and sorbitol.  Examples of suitable blowing agents are carbon dioxide (produced in situ) and fluorinated aliphatic hydrocarbons and mixtures of these. Other substances such as catalysts, acid dispersing agents, cross-linking agents, auxiliary blowing agents and pigments may also be added. Suitable catalysts are tertiary amines, tertiary amines containing hydroxyl groups, organic tin salts and organo-tin compounds.  Examples of suitable dispersing agents are polyethylene phenol ethers, blends of polyalcohol carboxylic acid esters, oil-soluble sulphonates and siloxaneoxyalkylene block copolymers.  The examples describe the preparation of fire-resistant rigid foams from phosgenated tolylene diamine and phosgenated p,p1-diaminodiphenylmethane with various polyols and additives and compare their fire-resistance with polyurethane prepared similarly from the corresponding pure diisocyanates.

Title: Device for continuous measurement and or monitoring of a width of an elongate object
IPC: G01B15/00
Filed: 1972-07-05
Abstract: 1378034 Measuring dimensions electrically INSTITUTET FOR MIKROVAGSTEKNIK 5 July 1972 [6 July 1971] 31425/72 Heading G1N A width of an elongated object e.g. steel strip, sheet or plate is determined by means of the effect of the object on a micro-wave energized transmission line. A sweep frequency from a micro-wave generator is coupled by means of an input loop to a transmission line comprising two parallel metal strips terminated at each end by a disc attenuator and arranged at right angles to the direction of movement of the steel strip whose width is to be determined and which passes underneath the transmission line. In the absence of the steel strip all the micro-wave energy fed into the transmission line is coupled out of the transmission line by an output line and fed to a detector and meter. The presence of the steel strip causes the characteristic impedance of the transmission line underneath which the strip passes to change so that some of the energy is reflected. The reflected energy is frequency dependent and the frequency at which maximum reflected energy occurs corresponds to the width as a number of half wavelengths of the frequency. The meter is calibrated to read directly in width. Alternatively the frequency of the minimum energy transmission corresponding to the width as an odd number of quarter wavelengths may be detected on the difference of the frequencies of the maximum and minimum energy transmissions detected.
