Patent GB-227370-A (GB)
Title: Improvements in or relating to the finishing and ornamentation of textile fabrics
IPC: D06P1/00
Filed: 1923-07-12
Abstract: Textile fabrics, such as cotton, linen, wool and silk, are finished or ornamented by applying such as by printing or padding a solution of cellulose in ammoniacal cupric oxide in conjunction with a reagent to precipitate the copper in the form of an insoluble copper compound.  The reagent may be applied before or after the cellulose solution, and mordants, pigments, dyestuffs &c. may be added to the cellulose solution to produce special effects.  A preferred cellulose solution is a 1-3 per cent solution of bleached cotton.  In examples the fabric treated with the cuprammonium cellulose is treated with ammonium molybdate to produce a light green, with ammonium vanadate for a yellowish green, with Rongalite to obtain a yellowish brown, and with caustic soda or soap solution to produce a dark brown or the effect of a brown on a mercerized ground or "crimp" or transparent effects on the unmercerized or previously mercerized fabric printed with the cellulose solution.  Treatment of fabrics which have been mercerized under tension with the above ammonium salts produces a velvety raised appearance.  Treatment or printing of the fabric with sulphides or polysulphides gives blackish greens or blacks, and may be carried out before or after dyeing with substantive, sulphur or other dyestuffs, or the dyestuffs may be added to the sulphide or polysulphide solution to produce, for example, a black pattern on a coloured ground.  The fabrics may be mordanted with tannins or with metallic mordants before or after the cellulose treatment and then dyed.

Abstract: 731,835. Differential switches. GENERAL ELECTRIC CO., Ltd., and MITCHELL, K. J. July 15, 1953 [July 21, 1952], No. 18398/52. Class 38 (5). [Also in Group XXX] In control apparatus for stopping the driving motor of a belt conveyer in the event of abnormal discrepancy between the speeds of the belt and driving drum (see Group XXX) a differential switch closes contacts in a control circuit when the speeds of two shafts 16, 13 driven respectively by the belt 12 and driving drum 11 differ by more than a predetermined amount. As shown, shafts 13 and 16 drive magnetic speedometer devices 18, 19 respectively which generate torques in the same direction on respective control members against the pressures of springs 20, the control member of device 18 consisting of a pair of arms 25, 26 carrying contacts 23, 24 while that of device 19 consists of a single arm 22 carrying a contact 21, which remains between contacts 23, 24 so long as the speeds of shafts 13, 16 remain equal. When a difference in speed occurs owing to slip of the belt on the driving drum, one of the control members is overtaken by the other so that contact 21 engages one of the contacts 23, 24 completing a circuit to stop the conveyer driving motor. The distance between the contacts 23, 24 determine the difference in speed of shafts 13, 16 necessary to operate the switch. In a modification (Fig. 2, not shown) the devices 18, 19 act in opposite directions on a common control member so that the control member moves only when a difference of speed of shafts 13, 16 occurs and will then engage one of a pair of fixed contacts spaced to suit the desired difference in speed to be permitted without operation of the switch.

Patent GB-997359-A (GB)
Title: Chemical process for pulping wood
IPC: D21C3/22
Filed: 1962-05-14
Abstract: Wood is pulped for the manufacture of paper by digestively treating it in sulphate cooking liquor to which has been added silicic acid or an alkali silicate, or more than one of these materials in an amount of 0.01% to 1% calculated as SiO2 as a percentage of the oven-dry weight of the wood treated.  Black liquor from the process may be evaporated and burned; salt cake may be added and the product dissolved and causticized with lime to yield a white liquor which can then be reused with further silicic acid or silicate.  A composite sheet may be made by supplying a major portion of pulp to the wire of a Fourdrinier machine, and then after partial dewatering superimposing a minor portion of pulp, the minor portion having been treated by the process of the invention, the major portion by a conventional sulphate process, or by a process using a lower proportion of silicic acid or silicate than the major portion.

Abstract: 1,131,919. Non-woven fabrics; forming web. HONSHU SEISHI K.K. 28 April, 1966 [12 May, 1965 (2); 11 June, 1965; 5 July, 1965; 6 July, 1965; 28 Jan., 1966; 25 March, 1966], No. 18783/66. Headings DIN and D1R. A dry process for making a non-woven fabric comprises defibring a natural fibre, synthetic fibre or mixture thereof, blowing the defibred fibres against a screen in a jet of air, so that single fibres pass through the screen while flocks are retained on the screen, drawing the screened fibres on to a first travelling wire-net conveyer by suction to form a non- woven web, transferring the web to a second endless wire-net conveyer, spraying adhesive on to the exposed surface of the web, drying, transferring the web to a third wire-net conveyer, a portion of which faces and runs parallel to the second, spraying adhesive on to the unsprayed surface of the web and drying. As shown, a web of bleached sulphite pulp from a roll 1 is fed between corrugated rolls 2 to two hammer mills 4 and 5 and blown by a fan 6 along a duct 9. Across the end of the duct are a travelling, endless screen belt 13 of about 10 mesh and a travelling, small-mesh wire-net conveyer 18. Flocks of fibres caught on the screen belt 13 are carried downwards to a suction box 14 connected to a duct 15 to return the flocks to the hammer mill 4. A suction box 19 draws the fibres passing through the belt 13 on to the conveyer 18. The web so formed is transferred successively to further wire-net conveyers 21, 29 and 33 by means of suction boxes 22, 30 and 34 and a blower 24. The two sides of the web are sprayed with adhesive from sprayers 23 and 32 assisted by suction boxes 26 and 31 and dried in chambers 28 and 36. The product is wound at 37. The adhesive may be a solution or emulsion of a copolymer of vinyl acetate and an ester of acrylic or methacrylic acid, mixed with a cross-linking agent which is a vinyl monomer containing an amino, amido, methylol or carboxyl group.
