Title: Manufacture of new monoazo-dyestuffs
Filed: 1951-07-17
Abstract: 1 - Alkyl - 3 - methyl - 5 - pyrazolones where the 1-alkyl group contains 4 or more carbon atoms are made by reacting the appropriate alkyl-hydrazine with acetoacetic amide or ester. Examples show the preparation of the 1-n-octyl and 1-n-dodecyl compounds.  Other specified radicals are n-butyl, isobutyl, n-amyl, n-hexyl, 2-ethylhexyl, n-decyl, cetyl and octadecyl.  The 1-alkyl-hydrazines are made as in Specification 695,513.ALSO:The invention comprises 1-alkyl-3-methyl-4-arylazo-5-pyrazolones in which the alkyl residue has at least 4 carbon atoms and the aryl group is a benzene or naphthalene residue, and their preparation from the appropriate diazo compounds and 1 - alkyl - 3 - methyl - 5 - pyrazolones.  When the diazo components are free from solubilizing groups the resulting dyestuffs are suitable for colouring hydrophobic materials such as fats, waxes, oils and resins and for dyeing or printing cellulose acetate and superpolyamides and superpolyurethanes; preferably the 1-alkyl group in the pyrazolone residue has 4-8 carbon atoms. Dyestuffs made from diazo components containing sulphonic or carboxylic acid groups may be used for dyeing or printing wool, leather, silk and nylon.  Metachrome or after-chrome dyes for wool are obtained from diazo compounds having an o-metallizable group (hydroxyl, alkoxyl or carboxyl) and a sulphonamide or methylsulphone group as the sole solubilizing group.  Similar chromable dyes for wool are produced from sulphonated diazo components having an o-metallizable group, the 1-alkyl group in the pyrazolone residue preferably having 4-12 (e.g. 8) carbon atoms.  In examples the following dyestuffs are prepared: (1) sulphanilic acid --> 1 - n - dodecyl - 3 - methyl - 5 - pyrazolone; (2) 4 - nitro - 2 - aminophenol - 6 - sulphonic acid --> 1 - n - butyl - 3 - methyl - 5 - pyrazolone; (3) 2 - aminophenol - 5 - sulphonamide --> 1 - n - butyl - 3 - methyl - 5 - pyrazolone; and (4) 3 - nitro - p - toluidine --> 1 - n - butyl - 3 - methyl - 5 - pyrazolone.  In further examples (5) wool is dyed yellow with the product of (1) from an acid bath; (6) wool is dyed yellowish red with the dyestuff 4-chloro-2-aminophenol-5-sulphonic acid --> 1 - n - octyl - 3 - methyl - 5 - pyrazolone by the metachrome process; (7) similar to (6) using the dyestuff from 1-n-butyl-3 - methyl - 5 - pyrazolone; (8) cellulose acetate yarn is dyed in a bath made up from the product of (4) pasted with sulphite cellulose waste liquor.  A table is given of other dyestuffs that may be prepared and further suitable diazo components are mentioned.

Title: Improvements in Machines for Reinforcing Paper and the like.
Inventor: HOWARD CHARLES HENRY
IPC: D21F11/00
Filed: 1916-12-05
Abstract: 108,622. Howard, C. H. Dec. 5, 1916. Strengthening paper w i t h threads and fabrics.-In reinforcing - machines f o r paper and the like, in which threads, tapes, or other strengthening-strips are applied transversely, t h e threads &c. from the source 74 are carried by grippers A to the central position shown in dotted lines, Fig. 1, and there seized by grippers B by which they are drawn through the grippers A and carried to the other side of the machine. When the threads are stretched across the machine, the studs 50 on the gripper-carriers 49 are at the right hand ends of the slots 51 and are then caused to travel along the slots, the threads thus travelling with the material a which is coated with adhesive. At the same time, the table or support 7 is raised, to press the material against the threads, which are severed as they pass a cutter 83, which may be a disk connected to arms 85. A second sheet of material c, gummed at 101 and passing round rollers 102, 103 connected by rods 106 to, and reciprocating with, the cutter 83, may be superposed upon the transverse threads, the compound material so formed passing out of the machine between rollers 32. The grippers comprise base portions 65, Fig. 8, having recesses 66 into which project blocks 69 mounted on spring arms 68 depressed by cam bars 71. The threads are cut so as to leave a projecting part b, Fig. 3, such as is required for the manufacture of tags. When the grippers meet in the central position, trip fingers 75, 76 engage the projections 73 on the bars 71, and, by turning these bars, open the grippers A and close the grippers B. On the return of the grippers A to the side of the machine, the projection 96 thereon engages a projection 97 on the side of the machine and closes the grippers A, which thus hold the threads while being cut and until presented to the grippers B. To open the grippers B when they reach the position shown in full lines in Fig. 1, the projection 76 turns a trip lever 78 carrying a projection 81 to engage the projection 73 on the cam bar 71 of the gripper B. The grippers, the table, and the cutter are operated by cams on the shaft 5, through links and levers, the arm 52 being swung to and fro by a cam acting through the agency of a toothed segment 57. The carriers 49 slide transversely of the machine in blocks 33, which slide longitudinally of the machine in dovetail connexions 34. Specification 108,618 is referred to.

Title: Improvements in cut-off devices for cigarette-making machines
IPC: A24C5/28
Filed: 1929-06-07
Abstract: 330,142. Triggs, W. W., (American Machine & Foundry Co.). June 7, 1929. Cigarette-making machines. - In a cut-off mechanism for continuous-rod machines in which a narrow cutting blade travels at high speed across the path of the cigarette rod, without any movement of the blade and its support parallel to the axis of the rod, the blade 34 is carried by the shaft of a high-speed electric motor 27 revolving about a second axis different from that of its shaft. As shown in Figs. 2 and 3, the blade 34 is mounted on arms 33 on the shaft 32 of the motor 27, which is secured upon a shaft 26 parallel to the cigarette rod C and driven from the main drive shaft 10 through spur gearing 12, 13, bevel gearing 17, 18, and helical gears 21, 25. The motor 27 is balanced by a counterweight 31, and the blade 34 is set at a slight angle in order to compensate for the slight axial movement of the cigarette rod during cutting. In order to time the cutting exactly with the rotation of the motor 27 about the shaft 26, the motor is of the synchronous type and is supplied with current by an alternating generator 24 driven from the helical gear 21. In a modification, Fig. 7, the motor 27 is rotated about an axis perpendicular to the cigarette rod C by mounting it on a vertical shaft 56 driven through bevel gears 54, 55 and helical gearing 46, 47, 50, 51; and the generator 24 is driven from the shaft 19 of the gears 47, 50 through bevel gears 48, 49.
