Title: Improvements in and relating to diazoamino derivatives
Inventor: PETITCOLAS PIERRE
Filed: 1954-10-20
Abstract: The invention comprises compounds of formula <FORM:0771070/IV(b)/1> where Y and Y1 are unsubstituted o-phenylene groups or halogen substituted o-phenylene groups and R and R1 are residues of diazotizable monoamines, and their water-soluble salts.  They are made by reacting appropriate diazo compounds in a non-acid medium with a compound of formula <FORM:0771070/IV(b)/2> in which the benzene nuclei may be substituted by halogen atoms or with their water-soluble salts.  Diazo components mentioned are derived from aniline, toluidines, xylidines, cresidines, anisidines, nitranilines, nitrotoluidines, nitrocresidines, nitroanisidines and aromatic bases containing sulphonamide, sulphone or trifluoromethyl groups, aminobenzthiazoles, aminoindazoles, amino azo dyestuffs and "solid bases" in general.  Preferably the diazo compounds do not contain water-solubilizing groups.  N,N1-di- and hexa-methylene-dianthranilic acids and halogen derivatives thereof are specified for reaction with the diazo compounds. The diazoamino derivatives may be used to prepare insoluble azo-dyestuffs on the fibre many of them splitting on neutral steaming.  In examples diazoamino compounds are made from 4- and 5-chloro-2-methyl-2-chloro-, 5 - methyl - 2 - methoxy - 4 - benzoylamino - and 5 - diethylsulphonamino - 2 - methoxy - anilines and N,N1 - di - and hexa - methylene - dianthranilic acids and N,N1-di- and hexa-methylene di-(5-chloro-2-aminobenzoic) acids.  The dicarboxylic acids used as starting material are made by heating 2-chloro- or 2,5-dichloro-benzoic acids with ethylene diamine or hexamethylene diamine in an autoclave in the presence of aqueous caustic soda, copper powder and copper sulphate.

Abstract: 176,837. Marks, E. C. R., (Republic Tool & Manufacturing Co.). Nov. 2, 1920. Moulding wheel tyres.-Pneumatic inner tubes are formed with identification marks such as the manufacturer's name &c. by moulding and curing them under pressure on a mandrel having such marks stamped ir intaglio on its surface. The mandrel, preferably of sheet metal, when made curvilinear, is formed by bending two flat pieces of metal away from the stamped surfaces into the shape shown in Fig. 6, the ends of the mandrel being bent out of alignment. Alternatively, the mandrel may be constructed of cast-metal having a plate of sheet-metal containing the identification marks incorporated therewith. Another form is obtained by rolling a flat blank with bent marginal portions to form a tube and bending the latter into circular form, as shown in Fig. 12, collapse of the tube being prevented by a button 11 supported on a stem 12. In moulding the tube raw rubber is first supplied to the outer surface in a uniform layer, and is then covered with long strips of wet fabric which, when dried, shrink and force the rubber into the indentations.

Abstract: 603,065. Water repellent materials. HOPLEY, M., LANE, E. S., and IMPERIAL CHEMICAL INDSTRIES, Ltd. Dec. 31, 1945, No. 30987. [Class 140] Textile materials are rendered water repellent by impregnating them with an aqueous solution or suspension of a high molecular weight quaternary ammonium salt containing a thermally decomposable quaternary group and (if desired after previous drying) the subsequent heating of the so-impregnated material to a temperature such that the said salt undergoes decomposition, the aqueous solution or suspension containing 5 per cent or less by weight of an alcohol or a phenol containing more than 6 carbon atoms. The quaternary ammonium salts include those described in Specification 477,991 e.g., stearamidomethyl-pyridinium chloride. Specified alcohols and phenols are 17-octanol, 2- ethylhexanol, pine oil, p.-(tertiary-butyl) phenol, and oleyl alcohol. The impregnation is preferably carried out at between 25‹C. and 40‹C. Polyvalent metal salts e.g., aluminium acetate, and other water repellent agents e.g., the diacyldiaminomethanes such as methylene distearamide, may also be present in the impregnating bath. The treatment may be applied in conjunction with a treatment with compounds used to confer creaseresistant properties e.g., condensation products of formaldehyde with phenols or with urea or urea derivatives, the two treatments being applied either separately or simultaneously i.e., from the same bath. In examples (1) a paste of stearamidomethylpyridinium chloride, methylated spirits and water is diluted by an aqueous sodium acetate solution and then by 2- ethylhexanol. Cotton gaberdine is impregnated with this mixture at 25-40‹C., dried, baked, washed with hot alkaline soap solution, rinsed and dried. The 2- ethylhexanol may be replaced by pine oil. (2) The quaternary ammonium salt obtained by reacting pyridine with the reaction product of stearonitrile. succinvl chloride and paraformaldehyde in the presence of anhydrous zinc chloride is diluted with aqueous sodium acetate and mixed with ethyl alcohol and n-octanol.

[Class 70.] A device for vulcanizing rubber soles to the uppers comprises a supporting plate and clamping members which are pressed upwards from the plate by a spring or equivalent means so that when they are clamped together thev come into contact with the rubber sole from above and ensure correct clamping of the upper. As shown in the drawings, a sole plate 3 is fixed to a supporting plate 1. Two sideheads or jaws 5, 6 provided on the supporting plate 1 are hinged at 8 and clamped at the opposite end. Plates 15 having decorative notches 19 are fastened to the members 5, 6. A bushing 17 of low heat conductivity is secured to each plate 15, and at foot and heel ends plates 16 are secured to the bushings 17. The side heads are pressed upwardly by springs 20 moving in cases 22a and held in place by stoppers 21 and studs 22. A rubber sole 23 is placed on the plate 3 and then an upper 34 mounted on a last is placed over it. The side-heads 5, 6 are brought together by the handles 9, 10 and secured by a lever 13 which turns about the handle 9 and has a slot which engages with the handle 10. The position of the clamped side-heads is ensured by a stud 11 engaging with an opening 12. The upper is pressed down upon the sole by pressure applied to the last. The side-heads are pressed down against the action of the springs 20 by the upper 34 which engages the inner margins of the plates 15, 16. The whole device is placed on a hot plate until the rubber has been vulcanized and the sole firmly secured to the upper. At the end of the treatment lever 13 is lifted away from handle 10 and the sideheads are forced apart by operation of a lever 36 which is fitted on the stud 37. The other end of lever 36 is tapered so that it may subsequently be used for removing the sole from the plate 3.
