Patent GB-421920-A (GB)
Title: Manufacture of mixed fabrics
IPC: D06P1/651
Filed: 1933-11-23
Abstract: Mixed fabrics consisting of cellulose esters highly acylated to different degrees are manufactured by treating materials, having components capable of different degrees of acylation under the same conditions, with an acylating agent until one of the components is substantially reserved to direct dyestuffs. Acylating agents may be acid anhydrides, e.g. acetic, propionic, butyric, valerianic, isovalerianic, monochloracetic, phthalic; acid chlorides, e.g. acetyl, propionyl, butyryl, palmityl, stearyl, benzoyl in presence of an alkaline catalyst (sodium or potassium acetate) or an acid catalyst (sulphuric acid, zinc chloride, copper sulphate) and with or without a solvent (benzene, xylene, chlorobenzene, perchlorethylene, pyridine) and with or without preliminary swelling of the material. Suitable cellulosic or regenerated cellulosic materials mentioned are cotton, ramie, linen, jute and viscose, Chardonnet, Lilienfeld, or copper artificial silk.  Effects may also be produced according to the pretreatment of the material, e.g. by mercerization.  Coloured effects can be obtained by the use of either acetate silk dyes or direct dyestuffs, and also with acid dyestuff if the fabric is dyed in a swollen condition (compare Specification 381,943). Multicolour effects can be obtained in one operation by using a direct dyestuff and an acetate silk dyestuff.  A fabric containing threads already dyed may be treated if the dye resists the acylating operation. According to examples: (1) A mixed fabric of cotton and viscose is impregnated with potassium acetate and acetylated with a solution of acetic anhydride in chlorobenzene at 95 DEG  C. or above.  (2) A similar fabric is treated in a bath comprising toluene, pyridine and benzoyl chloride, the temperature being raised to 90--95 DEG  C.  (3) The fabric obtained according to example 1 is dyed with Direct sky blue-green, the artificial silk portion being reserved and the cotton portion dyed blue.  If the fabric obtained according to example 2 is dyed with Direct sky blue-green shade or Direct fast orange SE the cotton portion is reserved and the artificial silk portion dyed.  (4) The fabric obtained according to example 1 is dyed in the manner usual for acetate silk with 4-nitro-4<1>-diethylaminoazobenzene or with 1 : 4-diaminoanthraquinone or with 1 : 4 : 5 : 8-tetra-aminoanthraquinone producing effects of the same shade but different depth, the artificial silk portion being more deeply dyed; by cross dyeing with Direct sky blue-green shade a two colour effect is obtained.  (5) The mixed fabric obtained according to example 1 is swollen with acetic acid, washed and dyed in the cold with addition of Glauber's salt with Orange II, the artificial silk portion being the more deeply dyed.

[Also in Division H3] In a twistor storage matrix in which permanent information is stored by the position of a bias field e.g. from permanent magnet 11 adjacent the storage areas, a sheet 19 of low magnetic reluctance material is provided to constrain the magnetic fields and prevent spurious outputs. In the embodiment shown in Fig. 1 words are stored by the position of permanent magnets 11 carried on a conducting metal sheet of, e.g., aluminium. The elements of the twistor matrix are then all switched to one state by premagnetizing source 25. To read a particular word conductor 15, 16 or 17 is pulsed, by bipolar source 27, which may be a biased switching matrix, switching those elements which do not have a magnet adjacent them and producing outputs in the twister wires 12, 13 and 14. During switching of the elements eddy currents in the plate 10 produce fields which support the switching field at the elements. As the mounting board 18 is screened by the low reluctance sheet 19 which may be permalloy the mounting board 18 may also be metal without producing adverse eddy currents. In a threedimensional matrix (Figs. 2a and 2b, not shown) adjacent magnet boards which may be spring-loaded are spaced apart by low reluctance sheets.

Abstract: 1,047,696. Bending fibrous cement sheets. F. L. SMIDTH & CO. A/S. Aug. 21, 1963, No. 33167/63. Heading B5A. In a method of giving fibrous cement sheets a permanent curvature, a straight, but possibly corrugated fibrous cement sheet 13 in its soft condition is deposited on a moulding sheet 14 having a curvature with downwardly facing concavity such that the fibrous sheet first contacts the moulding sheet at its centre, contact proceeding successively towards the sheet ends, the fibrous cement sheet being subjected for a brief period to a pressure which at any point of the sheet is directed towards the centre of curvature of the moulding sheet. A number of downwardly facing suction boxes 3 are mounted side-by-side on a vertically reciprocable framework. A soft corrugated straight fibrous cement sheet is held by suction to the lower faces of the boxes 3, and upon moving the framework downwardly towards a means 14 supporting a moulding sheet 13 the fibrous sheet is brought into pressurized contact with the moulding sheet successively from the centre outwards. The suction boxes 3 are connected to each other by a leaf spring means 6 which allows a limited freedom of movement of the boxes within the framework, the central boxes being free to rise higher than the outer boxes relative to the framework. Associated with the said framework are two lifting devices, (Fig. 3, not shown), comprising two suction boxes, all mounted together for joint movement along a horizontal conveying path, the lifting devices being arranged symmetrically on either side of the framework. One of the lifting devices is arranged for the lifting of curved moulding sheets and the other for straight moulding sheets.
