Patent GB-350417-A (GB)
Title: Improvements in processes for changing the solubility of cellulose acetate
IPC: C08B3/22
Filed: 1929-12-09
Abstract: Cellulose acetate is hydrolysed in the presence of a large excess of solvent at a comparatively low temperature and in the presence of sulphuric acid not exceeding 0,6 per cent of the weight of the bath. Another acid catalyst can be substituted for the sulphuric acid in a corresponding percentage according to its catalytic activity as compared with that of sulphuric acid, the corresponding figures being given for sulphuric acid, phosphoric acid, thionyl chloride, and p-toluene-sulphochloride.  In examples, to a solution of 80 parts by weight of cellulose triacetate in 500 parts of acetic acid is added 1 part of sulphuric acid, 3 parts of phosphoric acid, 37 parts of water, and 60 parts of glacial acetic acid, and the mixture is allowed to stand at 70 DEG  F., 80 DEG  F., 90 DEG  F., or 100 DEG F.  The acetyl content of the triacetate falls steadily from 44,8 per cent to about 34 per cent.  In a further example cellulose acetate soluble in chloroform is hydrolysed, using sulphuric acid only as catalyst. Specification 292,398, [Class 2 (ii), Cellulose &c.], is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) specifies a mineral acid catalyst from 0,1 per cent to not more than 1,0 per cent and other catalysts such as phenolsulphonic acid, acid sulphites, and sulphur chlorides in the ratio of their catalytic reactivities; it refers also to the use of a mixture of sulphuric and phosphoric acid in the pretreatment, acetylation, and hydrolysis stages.  This subject-matter does not appear in the Specification as accepted.

Patent GB-342075-A (GB)
Title: Improvements in and relating to the production of fabrics having ornamental effects thereon
IPC: D06M11/64
Filed: 1929-12-12
Abstract: Ornamental effects are produced on fabrics in which the warp or weft, or both, contains both yarns of an organic derivative of cellulose and yarns of another fibre, by treating the fabric with a reagent adapted to cause shrinkage of the component of the organic derivative of cellulose.  The cellulose derivative threads may alternate regularly with the other threads such as cotton, silk, reconstituted cellulose, or wool, or irregularly to form simple or complicated patterns.  Where the alternation is regular, pebble or cockled effects are produced when the fabric is treated with nitric acid, thereby causing shrinkage of the cellulose derivative threads.  The reagent may be applied locally by brushing or spraying through stencils &c.  Further effects may be produced by dyes having affinity for one kind of thread only. The cellulose derivative threads may be of cellulose acetate, formate, propionate, or butyrate, and may have a low twist or a high twist as employed in craping, and be sized or unsized when submitted to the shrinking-agent.

As described the circuit comprises a plurality of gates as shown in Fig. 2 each having a separate input I and common output O. Transistor T2 is normally blocked and T3 normally conductive so that + 5 v. is applied to the anode of D21 and D11 is reversed biased to block the signal path from I to O. To unblock the path, the base of transistor T1 is earthed, turning on transistors T1 and T2 and cutting off transistor T3. This reversed the bias conditions on diodes D11 and D21. The diodes D11 of the plurality of gates may be arranged in a star pattern around a common point on a printed circuit board having a ground plane on the other side, Fig. 3 (not shown). The remainder of the circuits are mounted on individual thickfilm circuit boards parallel to the main board and surrounding the diodes D11.

[Also in Divisions E1 and F4] The apparatus 17, Fig. 1 (not shown), for introducing feedwater into a feedwater tank or boiler 10 comprises a water inlet pipe 24a, Fig. 3 (not shown), which is surrounded by a cylinder 21a closed at its bottom end by a cap 23a and having at its top end radial brackets 25a attached to .a horizontal anti-surge deflector plate 26a. The cylinder 21a is mounted in the tank so that the maximum water level is about half an inch below the upper end of the cylinder. A double-ended fitting 27a is attached to .the top end of the pipe 24a which allows make-up water to be fed in from one side through a ballcock 14, Fig. 1, and steam condensate from pipe 18, Fig. 1, to be fed in from the other side. A small diameter steam inlet pipe 31a for heating the feedwater as it enters the tank 10 is passed through the fitting 27a and extends downwards to a point just below four radial holes 28a in the pipe 24a. Further heat may be given to the feedwater by feeding steam into a jacket 32 via pipe 33. The steam passes through tangentially drilled holes 34 in the cylinder 21a and mixes with the feedwater. In a modification the heating jacket 32 is dispensed with. The introduetion of the steam into the pipes 31a and 33 is controlled by cocks 35 and 36, Fig. 1, which may be replaced by thermostatically controlled valves. The apparatus may also be used in its basic form without steam heating for introducing water silently into the tank of a water closet cistern. In another embodiment (Fig. 5, not shown) the pipe 24a may be fed from an auxiliary tank mounted above the feed tank and feed water is initially fed into the auxiliary tank through a pipe 42 which is routed through the cylinder 21a and through a nozzle 43. A plurality of pipes 42 may be used each connected to separate ball-cocks arranged to operate at different water levels.
