Patent GB-920801-A (GB)
Title: A dyeing or printing process
Filed: 1959-03-23
Abstract: Natural or regenerated cellulose fibres are dyed or printed with reactive dyestuffs other than those containing a sulphofluoride or a halogeno-triazine group, by applying the dyestuff together with an acid-binding agent, without the application of heat, and then storing the so impregnated materials in the moist condition for 2-48 hours at 10 DEG -40 DEG C.  The acid-binding agent, e.g. an alkaline earth metal hydroxide, an alkali metal metasilicate or an alkali metal hydroxide, may be applied together with the dyestuff or may be subsequently applied. The dyestuff solution may contain a nonelectrolyte such as urea or a lower carboxylic acid amide, and an inorganic salt such as an alkali metal chloride or sulphate.  The acidbinding agent solution, when subsequently applied, preferably contains a high concentration of salt.  The dyeings are finally rinsed and soaped and, when appropriate, after-metallized.  Suitable dyestuffs are of the stilbene, thioxanthone, azine, dioxazine, porphyrazine, anthraquinone and azo series, and numerous examples are given.

[Class 100 (i)] [Also in Group XVII] A power machine for delivering measured lengths of strip, e.g. gummed paper, fabric or fibre tape, is so arranged that the removal of a strip 6, Figs. 1, 2 and 3, which has been fed by rollers 51, 55 from a roll 6a and severed by cutters 94, 95, reinitiates the delivery and severance of a strip. The strip passes from roll 6a under a pawl 14 knurled to resist backward movement, between edge guides 17 adjustable on a right-and-left screw 18 to the feed rollers 51, 55, whence it passes to shear blades 94, 95 and thence between pressure plates 151 and moistening brushes 149 and so beneath feeler 120, which, when allowed to fall by removal of the strip, closes a circuit. which applies a clutch wedge 100 by putting down a lever 107 on a shaft 104 and reinitiates the feed. As described below feed rollers 51, 55 are driven continuously from a motor 30 through gears 38, 44, 45, 46, 47, 48, 49 and shaft 50, this shaft carrying roller 51 and also a gear 52 which drives gear 53 and lower roller 55. Rollers 51, 55 are separated during the non-driving portion of the cycle by arranging gear 46 lower on a shaft 62 to which is keyed a yoke carrier 63 bearing a pivot pin 66 on which is pivotally mounted a clutch yoke 67 normally spring-pressed towards clutch plate gear 46 to engage its pin 68 in one of a set of holes 61 in plate 46. During the non-delivery part of the cycle, yoke 67 is held out of engagement with the clutch plate 46 by clutch wedge 100 and counterweight 64 which keep pins 68 from entering holes 61 and retains yoke 67 from slipping in counter-clockwise direction along wedge 100. The wedge 100 may also be withdrawn to engage the clutch by depression of a hand lever 105 at the front by the train of levers shown. Shaft 62 carries also a control disc 70, Fig. 3, carrying pins 71, 76 engaging respectively the lower and upper sides of lever 87 on a shaft 86 carrying a roller 85 which bears on a tail 84 of a yoke 80 having a second tail 82 which normally holds roller 55 against the strip and this against roller 51. The position of roller 85 determines whether or not the feed rollers are pressed together, the roller being actuated through clutch plate 46. The position of pin 71 on the periphery of control disc 70 is variable to vary the length of tape fed ; for this purpose it is mounted on an arm 69, Fig. 2, which can be clamped on to plate 70 by a nut 73 and which carries a micrometer adjustment. The upper cutting blade 94 is actuated by a link 92, Fig. 3, and shoulder 91a actuated from pin 71. Continuous delivery may be obtained by actuating a lever 108, Fig. 1, which keeps lever 105 depressed until return of lever 108. A pump for the moistening fluid is also embodied.

Abstract: 573,022. Furnace atmospheres. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Aug. 7, 1942, No. 11092. Convention date, Oct. 1, 1941. [Class 51 (ii)] [Also in Group II] Molybdenum trioxide is reduced by heating it in a mixture of a reducing gas, which may be hydrogen and an inert gas, which may be steam or nitrogen, shutting off the supply of inert gas when the reduction of the trioxide to dioxide is nearly complete, and continuing the heating in the reducing gas to complete the reduction to molybdenum. The temperature and the rate of flow of the reducing gas may be increased before shutting off the inert gas and may be maintained at the higher values until the reduction is complete. The trioxide may be moistened with water and passed through an extrusion machine of usual form for the formation of pellets which after drying are placed in boats 19 and passed through an inclined tube 23 in a furnace 21. Water for the formation of steam is admitted through a tube 24 and hydrogen through a tube 32, a small exhaust pipe 34 being provided. In a modification, the reduction to dioxide may be effected in ammonia and the reduction to molybdenum completed in hydrogen.
