Title: Improvements in machines for printing fabrics, paper and other materials
IPC: B41F13/20
Filed: 1947-06-30
Abstract: 661,854. Printing-machines. DUNGLER, J. June 30, 1947 [July 11, 1946], No. 17193/47. Class 100 (ii). The intaglio printing-cylinders 1, Fig. 1, of a fabric or like printing machine are mounted so as to be adjustable in positive axially and so as to be readily dismantled. The cylinders 1 are formed at the ends with internal conical surfaces adapted to be engaged by securing cones 13, 14 mounted respectively on a stub shaft 15, mounted in a support 18, and driven by a gear 21, and on a stub shaft 16, which is mounted in a support 19 adjustable by a screw 22, operable by a handle 23. The printing-roller 1 can be adjustable axially relatively to the impression roller 2 to vary the width of the printed impression by moving the supports 18, 19 relatively to a cross member 20. The invention can be applied to a multi-colour, machine in which a number of printing rollers coact with a large impression roller. Instead of using hollow cylinders with conical bores, solid copper printing-cylinders may be fitted at their ends with copper covered steel sleeves having conical bores, and the cylinders mounted as in Fig. 1. The printing-cylinders are supplied with ink by rollers forming a reservoir as described in Specification 633,006. The Specification as open to inspection under Sect. 91 also describes a modification, Fig. 2 (Cancelled), in which hollow cylinders 1 with a coating 1a of copper are formed with conical bores 5 for receiving conical mounted sleeves 6 which are adjustable on a driven shaft 7, geared to the impression cylinder. The sleeves 6 are keyed to and are adjustable along the shaft 7 and are held in adjusted position by lock nuts 12. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to photographic materials
IPC: G03C1/34
Filed: 1942-12-03
Abstract: The quality of images developed in silver halide emulsions is improved by treating the emulsion at a stage not later than its development with a small quantity of a 5-mercaptotetrazole.  The 5-mercapto-tetrazole may be incorporated in the emulsion, the developer, or in subcoat, supercoat, or backing layers, or may be applied in solution to the emulsion before development.  The use of the compound reduces chemical and age fog, increases the maximum obtainable image density, and improves the image colour. The preferred compounds are the 1-aryl-, 1-substituted-aryl-, 1 - aralkyl -, and 1 - cycloalkyl - 5 - mercapto - tetrazoles, although the unsubstituted and 1-alkyl-5-mercapto-tetrazoles may be used.  In some cases the compounds increase the effective speed of the emulsion. The 1-hydrocarbon substituent may be methyl, ethyl, higher alkyl groups, allyl, phenyl, naphthyl, benzyl, or cyclohexyl, and such groups may be substituted, e.g. by halogen atoms or amino groups. One part of the compound may be added to from 50,000 to 1,000,000 parts of emulsion or to from 3,000 to 100,000 parts of developer solution.  Examples are given of the addition of 1 - phenyl - 5 - mercapto - tetrazole to (a) a gelatino-silver-iodobromide emulsion, (b) a developer, and (c) a gelatine supercoat over a silver chloride emulsion coated on a paper support; of the addition of 1-a -naphthyl-, 1 - p - diethylaminophenyl -, 1 - o - methoxyphenyl-, 1 - p - chlorphenyl -, 1 - benzyl -, 1 - cyclohexyl -, 1 - methyl -, and 1 - ethyl - 5 - mercapto-tetrazoles to a silver iodobromide emulsion, and of the addition of 1-methyl-, 1 - a  - naphthyl -, and 1 - cyclohexyl - 5 - mercapto-tetrazoles to developers used for prints later hot-glazed.  The 5-mercapto-tetrazoles are prepared by condensing an azide (e.g. sodium azide with an organic isothiocyanate or, in the case of the 1-aryl compounds, by treating an aryl thiosemicarbazide with nitrous acid.  1-Phenyl-5-mercapto-tetrazole is prepared by adding sodium nitrite to a mixture of 4-phenyl-thio-semicarbazide, concentrated hydrochloric acid, and water cooled in ice.  1-Ethyl-, 1-benzyl-, 1-cyclohexyl, 1-a -naphthyl-1, p-chlorphenyl-, 1-p-methoxy-phenyl, and 1-p-diethylaminophenyl-5-mercaptotetrazoles are prepared from the corresponding isothiocyanates.

Patent GB-214507-A (GB)
Title: Process for producing batik discharge patterns
IPC: D06P5/15
Filed: 1923-07-03
Abstract: A process of Batik printing, especially suitable for heavy fabrics such as wool-plush, velvet and decorative materials, comprises printing the preliminarily dyed material with a discharge thickened with a wax-repelling substance, passing the material through a wax bath to effect the discharge, and finally setting the wax, breaking it, dyeing and de-waxing as in the ordinary Batik process.  For superposition of vein effects on the pattern, the material may be again waxed and treated as before. An example of a discharge is a mixture of rongalite and gum with tragacanth as wax-repelling substance.  In a modification, one part of the pattern is printed with discharge and another with tragacanth thickening, the waxing and dyeing being as described above, a two-colour pattern being thereby produced.
Patent GB-257059-A (GB)
Title: Improvements relating to levelling staves and like surveying instruments
IPC: G01C15/06
Filed: 1925-07-06
Abstract: 257,059. Sterr, W. C. van der, and Watts & Son, Ltd., E. R. July 6, 1925. Levelling-staves.-The face of a levelling or like staff is divided into a number of equal areas by means of sloping graduationlines, and each area is subdivided into a number of equal areas by lines parallel to the longitudinal axis of the staff, the areas being distinctively marked so that a reading can be taken without the use of any figures or numerals. Fig. 1 is a broken elevation of a ten foot staff graduated for reading in decimals of a foot, and Fig. 3 shows part of the staff as seen through an inverting telescope. Each foot is divided into ten equal parts such as a<0> - - a<9> by sloping lines, each part being also bisected by a sloping line. The face of the staff is divided by longitudinal lines into five strips each <1>/20 ft. wide so that each main division (<1>/10 ft.) is divided into ten lozenge- or diamond-shaped areas. The gradient of the sloping dividing lines is 1 in 5, so that the lowest point of any given line is in horizontal alignment with the highest point of the next line above. The main divisions are distinguished by bracket marks such as the arrow indications l. Alternate areas both laterally and longitudinally are made black and white for convenience of viewing. The markings which obviate the use of figures are as follows :-Supposing the ten areas in each main division to be numbered 0 to 9, as seen in Fig. 3, then in a given foot all the divisions have a distinctive marking such as red colouring, indicated by vertical hatching, in the same numbered area. For example in the divisions b<0> - - b<9> the red colour is in area number 1, in the divisions c<1> - - c<9> in area number 2 and so on. The first decimal place is indicated by circles m, n. marked in appropriate areas. Thus in the divisions a<0> - - k<0> the circle is in area number 0, in the divisions a<1> - - k<1> it is in area number 1 and so on. The second and third decimal places can be obtained by observing the position of the horizontal crosswire p in relation to the divisions on the staff. With the cross-wire in the position shown in Fig. 3 it is seen that the red area is in position 6 and the circle m in position 8. The second decimal place is obtained by observing which area has its upper edge intersected by the crossi wire. In Fig. 3 this area is in position 6, i.e. the red square. The reading thus far is therefore 6.86 feet. The third decimal place is obtained by estimating the distance from the top left-hand corner of the area concerned (number 6) to the point of intersection, in relation to the width of the area. If this distance is nine-tenths of the width the reading to three places of decimals is 6.869 feet.
Patent GB-356218-A (GB)
Title: Process for the manufacture of new sulphonic acids
IPC: C09K23/00
Filed: 1930-06-04
Abstract: Sulphonic acids are made by causing an alkyl- or aralkyl sulphonic acid or a salt thereof containing a labile halogen atom in the side chain to react with a higher aliphatic amine containing more than 8 carbon atoms, or by causing an aralkyl halide to react with a higher aliphatic amine and sulphonating. The products may be treated with alkylating or aralkylating agents until the aqueous solutions of the products are stable at least to weak organic acids.  They are useful in refining processes, e.g. as softening, purifying, frothing, wetting, washing and dispersing agents and for facilitating even dyeing.  In examples (1) b -chlorethanesulphonic acid (sodium salt) is condensed with hepta- or penta-decylamine in excess or in presence of pyridine or a dialkylaniline and extracted with ether; the products may be alkylated with dimethylsulphate; (2) benzylchloride - p - sulphonic acid is treated with heptadecylamine in acetone and caustic soda added and the crude product heated in vacuo; it may be alkylated in benzene with dimethylsulphate; (3) heptadecylamine is condensed with benzylchloride (1 or 2 mols.) and the products treated with chlorsulphonic acid in carbon tetrachloride; they may be alkylated as in (2).  Hepta- and penta-decylamine are obtained from stearic or palmitic acid by the Curtius reaction through the corresponding azides.

Patent GB-1111814-A (GB)
Title: Cross-linked polyphenylene oxides
IPC: C08G18/50
Filed: 1966-04-21
Abstract: Cross-linked polyphenylene oxides are obtained by reacting amino-substituted polyphenylene oxides with polyfunctional organic compounds capable of reacting with the amino groups to form cross-linking bridges.  The polyfunctional compounds may be di- or polyisocyanates, di- or poly-acid anhydrides, di- or poly-acid halides, di- or poly-esters of polyfunctional acids, di- or poly-glycidyl ethers or epoxy resins.  There may be from 1 amino group per repeating unit of the polyphenylene oxide to 1 amino group per 100 repeating units. When an epoxy resin is used it may constitute from 1 to 99% by weight of the total material. In examples polyphenylene oxides containing amino groups are obtained by reacting nitric acid with poly-(2,6-dimethyl-1,4-phenylene)-oxide and then reducing the resulting nitro groups with stannous chloride to amino groups, and by reacting poly-(2,6-dimethyl-1,4-phenylene)-oxide containing bromine substituents on the methyl groups and on the aromatic rings, with potassium cyanide and then hydrogenating the nitrile groups to amino groups; the amino-substituted poly-(2,6-dimethyl-1,4-phenylene)-oxides are then cross-linked by heating with a diglycidyl ether of 2,21-bis-(4-hydroxyphenyl)-propane, with pyromellitic di-anhydride, with toluene di-isocyanate, with 4,41-di-isocyanate-3, 31-dimethyl-diphenyl, with dimethyl terephthalate, with phthalic anhydride and with trimellitic anhydride.
