[Class 2 (iii)] Stilbene dyes are made by condensing, in the presence of caustic alkalies, dinitrostilbene disulphonic acid, dinitrodi-benzyl di-sulphonic acid or conversion products of p-nitrotoluene sulphonic acids with aminoazo dyes of the formula wherein X is hydroxyl, Y is alkoxyl, and the two benzene nuclei may be further substituted, and treating the products with agents yielding metal, and if desired with mild oxidizing agents. The aminoazo dye of the above formula may be replaced up to equimolecular proportions by another aromatic amine, e.g. another aminoazo dye. As diazo components of the azo dyestuffs are specified 2-aminophenol-4-sulphonic acid, 4 - chlor - 2 - aminophenol - 5- or 6 - sulphonic acid, 6-chlor-2-aminophenol-4-sulphonic acid, 3-amino-2-hydroxy-5-sulphobenzoic acid, 3- amino-4-hydroxy-benzoic acid, and 2-aminophenol-4:6-di-sulphonic acid, and as coupling components m-anisidine, m-methoxyphenylaminomethyl sulphonic acid, 2:5-dimethoxyaniline, and 1-amino-2-methyl-5-methoxybenzene. In examples, sodium dinitrostilbene disulphonate is condensed with (1) the dyestuff 2-aminophenol-4-sulphonic acid # m-anisidine or 2:5-dimethoxyaniline the products, after treating with copper, dye in brown or grey shades ; by treating the coppered products with sodium hypochlorite greenish dyeing products are obtained and (2) a mixture of the dyestuff 2-aminophenol-4-sulphonic and # 2:5-dimethoxyaniline with p-aminoazobenzene-p'-sulphonic acid, sulphanilic acid # m-toluidine, sulphanilic acid - m-anisidine, sulphanilic acid # 1-amino-3-methyl-6-methoxybenzene or similar dyestuffs, the products, when coppered, dye in grey, olive or brown shades. Specifications 311,384, [Class 2 (iii)], and 348,283 are referred to. The Specification as open to inspection under Sect. 91 includes also the use of aminoazo dyestuffs of the above general formula in which X is alkoxyl or carboxyl, and Y is hydroxyl. A number of such dyes is specified, and in additional examples sodium dinitrostilbene disulphonate is condensed with (1) the dyestuff 4-chlor-2-aminophenol-6-sulphonic acid - 2- amino-4-hydroxytoluene, either one or two molecular proportions of the stilbene compound may be used, and the products may be treated with ammoniacal copper sulphate to yield dyestuffs dyeing in brown shades, (2) the dyestuff 3-amino-4-methoxybenzoic acid # 2-amino- 4-hydroxytoluene ; the product is converted into the copper compound, and (3) the dyestuff 2-amino-4-sulphobenzoic acid # 1-amino-2- methyl-5-methoxybenzene; the product dyes cotton in brown-orange shades which may be after treated with copper sulphate. This subject-matter does not appear in the Specification as accepted.

A machine for packaging coins comprises a coin counter 18, Fig. 3, which supplies coins to a tube 24 formed from a web 10 of heat-shrinkable thermoplastic material, means 87 for heat sealing the longitudinal edge of said tube, jaws 26 which heat-seal the bottom of the tube, descend with the tube after a predetermined number of coins have accumulated therein, open, and ascend to seal the top of the tube, means operably associated with the jaws 26 to sever the tube of coins from the web, and means for heat-shrinking the sealed tube. The coin counter 18 supplies coins singly by means of an endless belt 40 to a shoot 20.

If the photo-cell registers an incorrect number of coins in the group, a solenoid (70), Fig. 7 (not shown), is activated to move the tube 22 over a container (not shown) to deposit the coins therein, to be returned to the counter 18. If the group is of the correct number a solenoid 72 is activated to withdraw the pallet 54 and deposit the coins in the web tube 24. The web tube is formed on rings 82, 84, and around a metal tube 25. The piston-operated heat-sealing jaws 26 are mounted on a carriage 86 fixed to collars 88 vertically slidable upon fixed guides 90. The carriage 86 is reciprocated by rods 94 connected to synchronously driven cams 92. Websevering means are located inside one of the jaws 26.

Abstract: 1,155,966. Crimping. KLINGER MFG. CO. Ltd. 23 June, 1966 [23 June, 1965], No. 26643/65. Heading D1F. Yarns travelling side by side obliquely across a heater 7 in a false twist crimping apparatus run through open-sided sheaths 6, 8 as they pass to and/or from the surface of the heater; thus when a yarn breaks it tends to be held away from adjacent yarns and is prevented from causing further yarn breakages. The sheaths which are preferably U-shaped channels, see Figs. 5, 6, 7 not shown, have a width such that the yarn normally runs freely therethrough but upon breaking jams therein due to the bulking of the contracting yarn. Sheaths 8 protrude at an angle from the casing of heater 7 and this angle will tend to prevent broken yarns running back along the length of the heater and into contact with other running yarns. Behind the heater there is a suction duct (19) Fig. 4, not shown, for fumes from the heater. This duct has hinged flaps (20) extending above the heater and these form an angle with the heater casing to minimize broken threads in this region moving along the length of the heater. As shown a tension sensing device 11 detects a thread break and actuates the associated cutter 5 to prevent yarn being fed by feed means 3 to the heater. If the yarns are being doubled the sensing means will also cause the associated constituent yarns to be severed. The heater is heated by hot oil flowing therethrough and is provided with insulating material on the sides not in contact with the yarns; it has a convex surface. The sheaths may be provided with a tongue to facilitate threading up.
