Title: Manufacture of new disazo dyestuffs
IPC: C09B35/28
Filed: 1948-02-02
Abstract: 4-Amino-3-carboxy-1-(41-methoxy-31-aminobenzoyl) anilide is obtained by reacting 6-nitro-3-amino-benzoic acid with 3-nitro-4-methoxy-benzoyl chloride and reducing the 4-nitro-3-carboxy-1-(41-methoxy-31-nitro-benzoyl) anilide with iron and aqueous ferrous sulphate.  Specification 451,100 is referred to.ALSO:Disazo-dyestuffs are obtained by coupling 1 mol. of tetrazotized 4-amino-3-carboxy-1-(41 - methoxy - 31 - amino - benzoyl) anilide with 2 mols. of the same or different 1-aryl-5-pyrazolones containing at least one solubilizing group but free from diazotizable amino groups and not containing hydroxy and carboxyl groups adjacent to one another, so that the final dyestuffs contain 2 or 3 solubilizing groups apart from the carboxyl group in the tetrazo component; "solubilizing group" means carboxyl or sulphonic acid group.  The same dyestuffs may be made by coupling a 1-aryl-5-pyrazolone with a diazotized 3-carboxy - 1 - (41 - methoxy - 31 - amino - benzoyl) anilide - 4 - azo - (11 - aryl - pyrazolone), the two pyrazolone residues containing substituents as listed above. The products may be after-treated to introduce substantially two atoms of copper per molecule.  They dye cotton and regenerated cellulose in orange shades of good light-and wash-fastness, the light-fastness being only slightly affected by crease-resisting treatments, e.g. with a urea-formaldehyde resin.  Examples are given of the two methods of preparing the dyestuffs and suitable pyrazolones as coupling components are listed.  The monoazo dyestuffs used as starting materials in the alternative process are obtained by coupling diazotized 5-nitro- or 5-acylamino-2-amino-benzoic acid with a 1-aryl-5-pyrazolone, reducing the nitro group or saponifying the acylamino group, reacting the product with 3-nitro-4-methoxy-benzoyl chloride and finally reducing the nitro group.  Specification 451,100 is referred to.

Title: Improvements in wirebound box machines
IPC: F02M59/36
Filed: 1921-01-07
Abstract: 156,741. Wirebounds Patents Co., (Assignees of Koch, H. J.). Nov. 11, 1918, [Convention date]. Angular bending; formers; twisting wires together; dividing by a single blade; power hammers.-In a machine for making wirebound box body blanks having cleats or strengthening-battens at the edges, the cleats and the parts intended to form the sides of the box are placed on intermittently-moving conveyer chains 3, Fig. 3, spacing-blocks being inserted between' the box side-members to snace them apart. Binding-wires fed from spools are secured to the blank by staples driven in by a stapling-device arranged over a bed 18, and the ends of the wires are subsequently severed and twisted into the form shown in Fig. 22. The conveyer is moved intermittently by means of a pawl 31, Fig. 3, on a rocking arm 32, a brake 40 being automatically applied to prevent overrunning of the conveyer. The backward movement of the arm 32, and hence the feed of the pawl 31, is determined by pawls 65, Fig. 5, on a slide 60, the pawls 65 being arranged to engage fixed rack teeth 66 when a spring-pressed pin 7'7 is pushed aside by an adjustable cam lever 80. After all the parts of a composite blank have been stapled to the binding-wires, the latter are cut and their ends twisted by mechanism mounted on a carriage arranged to move forward with the blank so as to avoid stopping the conveyer. The movements of the carriage are controlled by cams on the conveyer chain. The cutting and twisting mechanism are started by means of a lever 158, Fig. 10, which, when engaged by a pin 159 on the conveyer, releases a roller 155, thus allowing the cutting and twisting device to fall bodily so that the cutter 125 falls upon an anvil 129 on a spacing-block 128 and thus severs the wire. At the same time, pairs of twisting-jaws 122 fall so that pins 124, Fig. 18, engage beneath the wire, and notched plates 126 straddle the wire. Each pair of twisting-jaws is normally held open by a spring and is closed. when required, by a cam-actuated sleeve adapted to embrace the jaws. After severance of the wire, the carriage supporting the cutting and twisting mechanism moves to the left, and the parts 122, 125 are moved into the positions shown in Fig. 22 by cam grooves 141, 142, 143, Fig. 10, in a fixed plate 140, the pair of twisters being swung apart from one another. At the same time, the parts 126 are moved by a fixed cam into the positions shown in Fig. 22. The twisting-shafts 121, Fig. 10, are then turned on their axes by gearing 160, 161 driven from a pinion 151 engaging a fixed toothed rack 152, thus completing the formation of fastening-loops in the ends of the binding-wires. The fixed cams return the parts 122, 125, 126 to their normal inoperative position during the return movement of the carriage supporting the cutting and severing mechanism. The two fastening- Icops are made of different sizes, so that one may be passed through the other.
