Title: Improvements in dyeing cellulose acetate or materials containing it
Filed: 1924-12-16
Abstract: Compounds, which are dyes for cellulose acetate, are obtained from mono-, di-, or polyamino-anthraquinones or their derivatives by complete acylation with non-aromatic acyl groups followed by nitration.  The products may further be reduced or hydrolized.  In examples, 1.8- and 1.5-diacetyldiaminoanthraquinones are mononitrated and the products recrystallized from chloroform and the mononitro-1.8-diacetyldiamino compound is reduced with stannous chloride and hydrochloric acid to obtain the diacetyltriamino derivative or hydrolyzed with concentrated sulphuric acid to obtain the nitro-1.8-diaminoanthraquinone; 1.5- and 1.8-diacetyldiaminoanthraquinones are dinitrated and reduced or hydrolyzed.  The dinitration product of b -acetylaminoanthraquinone, the 2- and 4-nitroanthraquinonylurethanes and their products of reduction or hydrolysis are also referred to.  Specifications 211,720, 214,112, [both in Class 15 (ii), Dyeing, Processes &c. for], and 224,077, are referred to.ALSO:Cellulose acetate and materials containing it are dyed directly with or without the use of a dispensing agent, such as that of Specification 224,077, Turkey red oil or the like, with the products obtained from mono-, di-, or polyamino-anthraquinones or their substitution products (excepting sulphonic acids) by complete acylation with non-aromatic acyl groups followed by nitration or with the compounds obtained by hydrolyzing or reducing such products.  In examples diacetyl-1 : 8- or -1 : 5-diaminoanthraquinone is mono-nitrated and the products recrystallized from chloroform, brown shades being obtained on acetate silk with both compounds; the diacetyltriaminoanthraquinone, obtained by reducing with stannous chloride and hyldrochloric acid the mononitrodiacetyl-1 : 8-diaminoanthraquinone, gives crimson shades; and the nitro-1 : 8-diaminoanthraquinone obtained by hydroylsis of the same compound in strong sulphuric acid yields red shades.  The dinitro-derivatives of 1 : 5- and 1 : 8-diacetyldiamino-anthraquinones have little or no affinity for acetate silk but useful dyes are obtained by reducing or hydrolyzing them.  Dinitro-b -acetylamino-anthraquinone yields brown shades, while 2- and 4-nitroanthraquinonylurethanes, the nitroamines obtained by their hydrolysis, and the amino-urethanes obtained by reduction all give good results.  Specifications 211,720 and 214,112 also are referred to.

Title: Improvements in making coned tubes from sheet material
IPC: B21D37/18
Filed: 1939-11-29
Abstract: 541,546. Paper and like tubes. LOVE, W. Nov. 29, 1939, No. 31043. [Class 99 (ii)] Tubes with tapering bores are made by winding triangular blanks of paper or other sheet material point-first from a rotatable cylinder on to a rotatable mandrel composed of two separable cones disposed co-axially with their small ends together, so that the blank forms a tube with double-tapered bore which can be divided transversely to form two tubes each having a bore tapering from one end to the other. The outer surface of the tubes will be cylindrical when made from a triangular blank, but tubes with tapered exteriors also may be formed by using doubletriangular or diamond-shaped blanks. Further variations in the form of tube section may be obtained by concaving or convexing the sides of the triangular blanks. Fig. 4 shows a mandrel composed of cones 8, 8a having interengaging spigot and socket 12, 12a and driving- pins 10, 10a. Such a mandrel is carried by arms 14 on a shaft 15, which also carries an arm 16 connected at 24 to a spring link 26 and also to a lever 19, which is pivoted at 20a to links 20 so that by movement of the lever 19 the mandrel 8 is raised or lowered on to a rotatable cylinder A carrying the triangular blank, coated with adhesive, around its periphery. The point of the blank is led around the centre of the mandrel, which is then rotated by a hand wheel 9b, so that the blank becomes coiled thereon to form the tube with doubletapered bore. When the arms 14 are raised, the tube and mandrel roll down an incline 27, and the tube is detached. The tube may then be trued in a press consisting of a cylindrical matrix with a double-conical die similar to the mandrel, the matrix being heated. The tube is then placed upon another double-conical mandrel forming part of a trimming-machine with three rotary cutters, two of which trim the ends, while the third severs the tube at the centre, thus producing two similar tubes with tapered bores.
