163	Steel converter anchoring in carrier ring	FR7027742	1970-07-28	FR2067279A7	1971-08-20
Steelworks converter is supported by a carrier ring with peg, to each of which is attached a yoke linked by a flexible joint with two tension rods fitted tangentially to the carrier ring. A plate with a ball shaped portion fitting into a notch of the peg plate is fitted to the bracket of the converter and one of the tangential tension rods. Three vertical tension rods with ball and socket joints are fitted on the two sides of the longitudinal axis of the peg. This arrangement ensures that the converter is at all times held rigidly in the carrier ring and is yet able to compensate for thermal dimensional changes and distortion.

2 - Amino - 4 - methylsulphonyl - 31 - hydroxydiphenyl ether is prepared by reacting 1-chloro-2 - nitrobenzene - 4 - methyl sulphone with resorcin in the presence of sodium carbonate, copper powder and n-amyl alcohol to obtain 2-nitro - 4 - methylsulphonyl - 31 - hydroxydiphenyl ether and reducing the latter in aqueous solution with iron. 2 - Amino - 4 - methylsulphonyl - 31 - dimethylamino-diphenyl ether is obtained similarly using 3 - hydroxy - N,N - diethylaminobenzene instead of resorcin. 2 - Amino - 31 - hydroxy - diphenylthioether is obtained by reacting m-aminothiophenol with o-nitrochlorobenzene, treating the product to obtain the hydrochloride of 2-nitro-31-aminodiphenylthioether, diazotizing the latter, treating with hot aqueous sulphuric acid and reducing the product by catalytic hydrogenation or the B<\>echamp method. 2 - Amino - 4 - methylsulphonyl - 31 - acetylamino-diphenylthioether is obtained by reacting 1 - methylsulphonyl - 3 - nitro - 4 - chlorobenzene with m-aminothiophenol, acetylating the product and reducing with hydrogen and Raney nickel.

898,168. Typewriters &c. COMPAGNIE DES MACHINES BULL. April 28, 1959 [May 14, 1958], No. 14544/59. Class 100(4) A printing machine comprises continuously rotating type wheels for printing on record cards or separate sheets. In the example described data on a record card is analysed column by column and similarly printed on the card itself. Cards are placed in a magazine 21 and are removed by a reciprocating knife through slots 68, 69 to be fed by rollers 51-54 over a contact plate 116 past the analysing and printing position to a receiving compartment 23. The cards are held in the magazine 21 out of the feeding position until an electromagnetic device allows them to be lowered into the path of the extractor knife. A shaft 29 mounts a printing wheel 37 and a magnetic distributer DM drives in synchronism therewith. The printing wheel is in line with the card analysing brushes 85 which scan the record cards continuously column by column as they pass. A hammer 111 which is actuated by an electromagnet 93 effects impression on the card C by means, of an ink ribbon 96 when the character on the print wheel 37 appropriate for the datum of a column being analysed is in the printing position. The wheel 37 rotates once for every column analysed and is divided into five equal parts four of which contain up to nine characters arranged in a helix. The magnetic distributer has nine coils which can each produce a pulse during each part of a column sensing cycle as the corresponding character of a corresponding part of the type wheel 37 is in the printing position. Pulses derived from the eleven position code sensed column by column are first fed through a decoding diode matrix which reduces them to a seven position code for feeding to a double relay contact pyramid which sets up a circuit to the appropriate distributer coil. The appropriate part of a column cycle for the connection to the coil is selected by cam actuated contacts each of which is closed once every column cycle and only one of which is in the circuit set up by the relays when the column is sensed. Thus a circuit is set up to a distributer coil to receive a pulse when the appropriate character is in the printing position and the pulse is fed to a control grid of a triggering tube which allows a condenser to discharge through the hammer electromagnet 93 to effect impression. The condenser is charged during the blank part of each column cycle. In modified arrangements a seven position record card is used in which case a diode matrix is unnecessary the pulses being fed directly to the double contact relay pyramid. In other cases a double deck record card is used in conjunction with two analysing and printing devices while all the columns may be sensed simultaneously and a printing wheel for each column used to effect line printing on a separate record sheet. Card feeding can be stopped by manually opening contact or by contacts in series therewith opened when the card supply magazine 21 is emptied or the receiving compartment 23 becomes filled.

175	Process for producing azo-dyestuffs insoluble in water on textile materials of aromatic polyesters	GB2039458	1958-06-25	GB863329A	1961-03-22
Azoic dyeings or prints are produced on aromatic polyester textile materials by applying an arylamide of an aromatic or heterocyclic o-hydroxycarboxylic acid or of an acylacetic acid which contains a diazotizable amino group (or a nitro group to be reduced in situ to a diazotizable amino group) and then effecting diazotization and self-coupling on the fibre. The arylamide may be applied in the presence of solvents, dyeing promoters, protective colloids and dispersing agents such as diacetone alcohol, diglycol, butyl alcohol, methoxybutanol, dimethylformamide, tetrahydronaphthalene, methylbutanol acetate, tartaric acid diethylester, glue, sulphonated castor oil, a protein condensation product, oleylmethyltaurine, a hydroxyethylated fatty alcohol or a hydroxyethylated alkyl phenol. When the arylamide contains a nitro group it may be reduced to the amino group by sodium dithionate, thioureadioxide or ammonium sulphide. Examples are given.

179	Metal containing polyazo dyestuffs	GB2541156	1956-08-20	GB818008A	1959-08-12
The invention comprises dyestuffs of formula where X is H or -N=N-R1 and R and R1 are residues of diazo components of the benzene, naphthalene or stilbene series. This may be made by coupling the copper coupler of an appropriate naphthalene-azo-naphthalene dyestuff with the desired diazo component. The copper complex of the naphthalenic starting material may be made by reacting 2-diazo-1-hydroxy - 5 - o - benzene - sulphonyloxnaphthol - 7 - sulphonic acid with an appropriate ammoniacal copper salt solution and saponifying the product. When the products are derived from diazo components containing complex-forming groups such as the salicylic acid grouping and those in o-position to a diazo group, they may be metallized in substance or on the fibre. Indicated diazo components and anilines, o-aminobenzenecarboxylic acids, 1-amino - 2 - methoxybenzenes, naphthylamines, 4-aminoazobenzene sulphonic acids and 4-amino - 41 - nitrostilbene - 2,21 - disulphonic acids. The dyestuffs dye vegetable fibres, such as cotton and regenerated cellulose, in green shades. In examples, illustrative of the preparation of dis-, tris- and pentakis azo dyestuffs and their use in dyeing processes, the diazo compounds used are aniline, 2-amino-4-nitrophenol, o-anisidine, aniline-2-carboxylic and sulphonic acids, 2-naphthylamine-8-sulphonic acid, N - acetylbenzidine - 31 - sulphonic acid, 4,41 - nitramino - stilbene - 2,21 - disulphonic acid, 1 - (41 - aminobenzoylamino) - 4 - phenol-3-carboxylic acid and 4-amino-azo-benzene-41-sulphonic acid, some of the dyeings being after-coppered, chromed or treated with diazotized p-nitraniline and one after-treatment by an in substance coppering process is also described. Specification 802,098 is referred to.
