Title: New triazenes
Inventor: HADFIELD HARRY ROSE
Filed: 1952-06-25
Abstract: Textile materials are coloured by applying thereto a triazene of the formula <FORM:0730653/IV (c)/1> and an o-coupling aromatic hydroxy compound (free from carboxylic acid and sulphonic acid groups) or a 1-aryl-3-methyl-5-pyrazolone, treating with acid to effect coupling on the fibre and then metallizing.  In the formul  R1 is H or a substituted or unsubstituted alkyl, aralkyl or cycloalkyl radical, R2 is a substituted or unsubstituted alkyl, aralkyl or cycloalkyl radical, or R1 and R2 together may form a heterocyclic ring, X is cyano, guanyl or substituted guanyl, and the benzene nucleus may carry substituents other than carboxylic acid or sulphonic acid groups.  When applied to nylon the metallization may be carried out as in Specification 631,073 (chroming) or 678,106 (coppering).  The coupling and metallizing may be carried out in the same bath.  In an example: (1) nylon textile material is added to a bath containing 2 : 7-dihydroxynaphthalene, sodium chloride and the triazene from diazotized 5-nitro-2-aminophenol and piperidine; coupling is effected in a subsequent bath containing hydrochloric acid, and the dyed nylon is then either chromed with potassium dichromate, formic acid and sodium thiosulphate or coppered with cuprous chloride, sodium chloride and formic acid. Similarly a dyeing can be obtained from b -naphthol and the triazene from diazotized 5-nitro-2-aminophenol and piperidine.  A further example shows the development and metallizing in the same bath.  Other suitable triazenes and components therefor are mentioned, together with additional coupling components.ALSO:The invention comprises triazenes of the formul  <FORM:0730653/IV (b)/1> where R1 is H or a substituted or unsubstituted alkyl, aralkyl or cycloalkyl radical, R2 is a substituted or unsubstituted alkyl, aralkyl or cycloalkyl radical, or R1 and R2 together may form a heterocyclic ring, X is cyano, guanyl or substituted guanyl, and the benzene nucleus may carry substituents other than carboxylic acid or sulphonic acid.

Filed: 1972-04-10
Abstract: 1365629 Polyurethane foams BAYER AG 10 April 1972 [10 April 1971] 16337/72 Heading C3R Polyurethane foams are prepared by reacting, in the presence of a blowing agent, a polyhydroxyl compound of M.W. 100 to 10,000 and a polyisocyanate which is a solution in 2,4- and/or 2,6-toluylene diisocyanate of 2 to 60% by weight of undistillable material, the undistillable material being the material remaining as residue after distillation of phosgenation products of 2,4- and/or 2,6-toluylene diamine, and in which in the polyisocyanate solution 1 to 45% by weight of the free NCO groups have been converted into biuret groups. The polyisocyanate solution may comprise the crude phosgenation product of 2,4- and/or 2,6-toluylene diamine, from which some of the toluylene diisocyanate may have been distilled off, which is subsequently treated to produce biuret groups. Alternatively undistillable material remaining after distillation of a toluylene diamine phosgenation product may be dissolved as such in distilled 2,4- and/or 2,6-toluylene diisocyanate before treatment of the solution to produce biuret groups. The polyhydroxyl compound is preferably a linear polyether, especially one in which at least 5% by weight of the OH groups are primary OH groups. Conventional catalysts, emulsifiers, pore size regulators, fillers, dyes, plasticizers and/or flame-retarding additives may be incorporated in the reaction mixture.

Filed: 1944-08-28
Abstract: 590,506. Wireless signalling. MAR CONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 28, 1944, No. 16348. Convention date, Feb. 12, 1942. [Class 40 (v)] A radio repeater station comprises a source of received high-frequency energy, two oscillators, one producing low-frequency oscillations having a high degree of frequency stability, a modulator for producing sum and difference frequencies from the outputs of the two oscillators, a first converter to which the received. signal and one of the output frequencies of the modulator are applied in order to produce a low intermediate frequency, an I.F. amplifier, and a second converter to which the amplified I.F. and the other output frequency from the modulator are applied in order'to produce a high-frequency output signal at a frequency adjacent to that of the received signal. In a preferred form Fig. 2, a crystalcontrolled oscillator 10 produces a signal of low-frequency,fk, which is mixed with a signal of frequency fc derived from oscillator 14 in a balanced modulator .12 to give sum and difference frequencies fc+fk. The incoming signal of frequency fs and the difference frequency are applied. to the first converter 16 to give a low I.F. fs - fc+fk, which is amplified by amplifier 18. The amplified. I.F. and the sum frequency fc+fk produced by modulator 12 are mixed in the second converter 20 to give an output signal of frequency fs +2fk. In order to avoid clipping of the side bands in amplifier 18 due to variations in ,fc, a back-to-back discriminator 22 in which the characteristics of the halves of the discriminator are as shown in Fig. 3, is used to provide an automatic frequency control voltage to oscillator 14. In a modification Fig. 4, the output fk of the crystalcontrolled oscillator 10 is used to modulate the output of oscillator 14 in modulator 24, which may be a frequency modulator. The modulation index is adjusted to obtain the most favourable relation between the required frequencies, fc+fk and fc - fk, and the other frequencies present in the output of modulator 24. The incoming frequency in this modification is taken to be fs+2fk, and this signal is mixed with the output fc+fk from filter 30 in first converter 16 to give an I.F. fs - fc+fk. The output from amplifier 18 is then mixed with the output fc - fk of filter 32 in second converter 20 to give an output signal of frequency fs for retransmission. In a radio relay system using this type of repeater station, the output frequencies of the individual radio repeater stations may be alternately fs+2fk and fs, while the received signals are of frequencies fs and fs+2fk alternately.

[Also in Divisions B1 and B2] In the production of easily-wettable powdered substances, e.g. dried skimmed milk or whey, the material to be dried is first concentrated to a solids content of 40 to 52% by weight and then introduced into a stream of hot air moving at a speed of 10 to 150 metres per second whereby the material is dried to a powder but the exhaust air temperature does not exceed 90‹C., and returning the fine grain portion of the powder to the drying zone. The powder obtained as product has a specific weight of at least 680 grams per litre, and the average air-inclusion in the particles is less than 10% by volume. The concentrated liquid is preferably introduced into the drying zone through a nozzle 18 (Fig. 2) which is surrounded by cold-air nozzle 16 which is itself surrounded by the nozzle 6 which supplies the hot drying air. Nozzle 18 may be replaced by a plurality of tubes for the liquid. In an example, skimmed milk concentrate having a solids content of 48.5% is forced, at a temperature of 60‹C., to nozzle 18; filtered air at about 300‹C., is supplied to the outer nozzle 6; and compressed air at 20‹ to 70‹C. is conducted to the intermediate nozzle. A turbulent jet of air containing fine drops of skimmed milk enters the top of a drying column, where the temperature is 84‹C. The dried powder collects in the conical base of the column and is deposited on a shaker-trough from where it is conveyed to a packing station. The exhaust air withdrawn from the top of the column carries the fine grain powder which is removed from the air in separators; the fine powder is pneumatically returned to the central section of the drying column. Fig. 5 shows a nozzle 42 attached by a screw thread to a liquid supply tube 38. The gap 37 between the mouthpiece 43 of the nozzle and a stationery end plate 32 can be adjusted while the nozzle is in operation, by rotating the nozzle by means of rod 47.
