Title: Improvements relating to metallisable polyazo dyestuffs derived from 1-amino-8-naphthol-6-sulphonic acid, complex copper compounds thereof, and their use
IPC: C09B45/28
Filed: 1957-07-31
Abstract: The invention comprises dyes of formula: <FORM:0840898/IV (c)/1> where R is an alkyl, benzene or acyl residue bound directly to the amino group via the (C=0)-group, X is a metallisable substituent and A is the residue of a naphthol sulphonic acid coupled #s to the OH group and copper complexes thereof.  They may be made by coupling approppriate tetrazotised 4, 41-diaminodiphenyls with the necessary naphthol sulphonic acids with coppering if desired.  Coppering may be effected in substance or on the fibre. Specified as metallisable groups are carboxy, hydroxy, p  carboxymethoxy and methoxy, the latter being preferred.  R is preferably an acyl group specified being acetyl, chloro-, methoxy- and phenoxy-acetyl, benzoyl, chlor-and alkyl-benzoyl and carbomethony and -ethoxy groups. Specified for A, which may be the same as the other naphthol component, are 1-naphthol-3- and -4- mono-, -3, 6-, -3, 8- and -4, 8- di- and -3, 6, 8-tri-sulphonic acids, 2-naphthol-6- mono- and -3, 6- and -6, 8-disulphonic acids, 1, 8-dihydroxynaphthalene -3, 6- and 1- naphthol -8- chloro- and -ethoxy -3, 6- disulphonic acids, N-acetyl-, -benzoyl- and -phenylderivatives of 1- amino -8- naphthol-3, 6- and -4, 6- di-, 1- or 2- amino -5- naphthol -7-, 2- amino -6- naphthol -8- and 2- amino -8- naphthol -6- mono-sulphonic acids. Amino-naphthol-sulphonic acids containing arylazo substituents may also be used.  Dyes containing 3 sulphonic acid groups are preferred because of their water-solubility.  Cellulosic fibres are dyed by the metal-free dyes in blue shades which may be fixed by an after coppering process.  The copper complexes dye cellulose material in reddish to greenish-blue shades.  In examples which illustrate the preparation of the dyes and their use in dyeing processes the reactants used are chosen from those indicated above additional values for R being b , b -dimethyl-acrylyl-, propionyl- and b -ethoxycarboethoxy-amino and methyl-, ethyl-, b -hydroxyethyl, phenyl- and 4-methoxyphenyl and for A are 2-(31-sulphophenylamino)-5-naphthol-7 and -8-naphthol -6- sulphonic acids and salicylic acid, 2-amino -5-nitrobenzene- and 5-amino -2- hydroxybenzene -1- carboxylic acids and aniline -->2-amino -5- naphthol -7- sulphonic acid.

Title: Improvements relating to data storage apparatus
IPC: G11B5/004
Filed: 1955-08-24
Abstract: 778,112. Fluid bearings. TAYLOR, M. K. Aug. 24, 1955 [Sept. 1, 1954], No. 24296/55. Class 12 (1). [Also in Group XIX] Data-storage apparatus (see Group XIX) comprises a magnetic drum supported on a gas bearing. The drum 10 is formed with a cylindrical or frusto-conical bore 15 which fits over a correspondingly shaped mount 16. Air is pumped through a connection 17 into the mount and through passages 19, 20 and 21 to support the drum. The air escapes round the bottom of the drum and through passages 22 in it. A flanged sleeve formed with slots to permit the flow of air from the passages 19, 20 and 21 may be rotatably arranged on the'mount 16, between it and the drum, so as to form a frictional bearing for the latter should the air supply fail.

Title: Improvements in or relating to the drawing and crimping of synthetic filaments and yarns
Inventor: BLERK VICTOR BRUCE VAN
IPC: D02J1/22
Filed: 1962-06-26
Abstract: 961,094. Stretching and bulking yarns. BRITISH NYLON SPINNERS Ltd. May 28, 1963 [June 26, 1962], No. 24423/62. Heading B5B. [Also in Division D1] In a process for drawing and bulking monofilament or multifilament synthetic e.g. nylon, yarn, undrawn yarn is forwarded (directly from the filament spinning machine or a spinning package) at a predetermined rate to nip rolls of a stuffer-box crimper which are rotated at a peripheral speed at least twice the linear speed at which the yarn is forwarded thereto so as to draw it. The heat engendered in the yarn by the drawing action is sufficient to set the crimp imparted by the immediately subsequent operation. This heat may be limitatively controlled, according to the position of the point of draw in relation to the nip rolls, by a friction device e.g. a snubbing pin. As shown, yarn 1 (the filaments of which may be of trilobal crosssection) is fed by rollers 3 through guide 5 into the nip of rolls 7, 9, and is crimped within the stuffer zone between rolls 7, 9, and a discharge wheel 11 the rotary speed of which determines the crimp frequency which may thus be preselected and maintained constant in the yarn withdrawn by rolls 17. Specifications 852,579 and 873,368 are referred to.

Title: Improvements in or relating to an ink and moisture applying mechanism for lithographi
IPC: B41F31/30
Filed: 1950-10-06
Abstract: 693,183. Rotary printing-inachines. ADDRESSOGRAPH-MULTIGRAPH CORPORATION. Oct. 6, 1950 [Oct. 11, 1949], No. 24444/50. Class 100(ii) An ink and moisture applying mechanism for lithographic printing machines wherein ink and a moistening solution are fed from an ink fountain and a moisture fountain respectively to a master sheet mounted in the machine so as to enable an image on the master sheet to be reproduced includes a sheet engaging roller engageable with the master sheet, a first train of rollers for picking up ink from the ink fountain and transferring it to the sheet engaging roller, a second train of rollers for picking up moisture from the moisture fountain and transferring it to the sheet-engaging roller, the engagement pressure between some of the rollers of the second train being adjustable so as to regulate the amount of moistening solution withdrawn from the fountain. Damping apparatus.-(Figs. 1, 2, 5). As shown a lithographic offset printing machine comprises a roller 100 to which a master sheet 115 is attached. The roller 100 drives through gears 150, 152 a blanket cylinder 102 and is driven through gearing from a motor by a gear 146 which also drives an oscillating roller 148. The roller 148 takes up ink and moisture from roller trains 451, 452, and 490, 491 and 492 respectively and supplies them to a roller 455 co-operating with the roller 100. The moisture supply unit SU comprises a container 523 supplying a pan 480. The pan 480 has side walls including roller bearing arms 485 having bearings 495 which support the rollers 490, 491, 492. The pan is supported by shiftable plates 501 formed with a portion 507 and slots 502, 503 for cooperation with a tie rod 512, studs 514 and screws 504 on the machine so that the pan 480 may be removed if desired. The amount of moisture which is fed to the roller 148 may be adjusted by means of a screw 535, fitted with a locknut 533, which co-operates with a pressure pin 525 bearing against the shaft of the roller 490, a screw and pressure pin being provided at each end of the roller shaft. As the pressure between the rollers is varied so the amount of moisture fed to the roller 148 is also varied. To ensure an even distribution of moisture and to ensure that an excessive amount of moisture is not fed to roller 148 the roller 492 is formed with a helical groove 492G therein. Inking apparatus.-(Fig. 1). Ink is supplied to the roller 148 by means of a fountain roller 451 in an ink fountain 450 and a ductor roller 452 mounted for rocking movement on a shaft 454. By means of an arm co-operating with a manual lever (Fig. 6, not shown) the ductor roller may be held against the roller 148 for cleaning purposes. A ratchet wheel fixed on the shaft of the roller 451 allows a small indexing movement to be imparted to the roller 451 at each cycle. A cam rod 458 having a lever fixed on one end co-operates with a frame 456, so .that the roller 455 may be separated from the cylinder 100.
