Title: Production of stable bands of staple fibres
IPC: F21V1/00
Filed: 1970-03-21
Abstract: 1311798 Spinning processes PAVENA AG 21 March 1970 [21 March 1969] 10831/70 Heading D1F A spinnable, longitudinally stable band of adhesively interconnected staple fibres is produced continuously or discontinuously by applying an excess of liquid in which an adhesive is distributed to a fibre band (produced by a preparatory machine, e.g. such as a carding engine) in endless or successive fixed lengths thereof, squeezing off the liquid surplus and compressing the fibres into the form of a compact sliver and elongating the sliver within the limits of elastic deformation while setting of the adhesive occurs as a result of liquid, e.g. a solvent, removal as by heating, radiation; ionisation or use of gases. The elongation results from tension which is maintained constant or variably increased or decreased. The sliver may be elongated before setting with its length maintained constant, e.g. by clamping, in which case the final elongation is subject to change according to tension generated by the developed shrinkage. In the continuous process shown in Fig. 9, a compressed sliver 2 emerging from an applicator I transfers, perhaps with an increase in speed, at A to a rotating drum 4 along the surface of which it travels under tension in a helical path and leaves at B as a stable band. The adhesive is set in a processing zone within a housing 5 and under tension conditions which may be determined according to whether the drum 4 is of uniform diameter or tapered in one sense or the other. In another method, Fig. 10 (not shown) compressed sliver treated with adhesive is guided directly through a processing zone and then wound into a package at a speed which subjects it to the required tension. The adhesive may be starch and its derivatives, carob seed derivative powder, cellulose derivatives, polyacrylate, polyvinyl alcohol.

Title: Process for the preparation of gall acids
IPC: C07J9/00
Filed: 1927-04-22
Abstract: 269,925. Chemische Fabric vorm. Sandoz. April 24, 1926, [Convention date]. Cholic acid and other bile acids.-The crude bile acids obtained by adding mineral acids to saponified ox-gall are stirrea with a fat solvent and an aqueous solution of a salt of a weak acid, such as sodium acetate, sulphite, bisulphite or cholate or calcium carbonate. The solvent removes the fatty acids and coloured substances and the bile acids are obtained as a yellowish crystalline powder, which is washed with the fat solvent and water and then dried. By treatment of this product with alcohol, about 75 per cent of nearly pure cholic acid is obtained; it is purified by recrystallization from alcohol and decolorization with charcoal. Instead of using the salt of -a weak acid as above described such a salt may be added to the saponifying alkali; or an acid such as acetic acid may be added to the saponification product to neutralize a part of the soda; or the neutralization of the saponified product with mineral acid is carried out carefully so as to avoid any local excess of mineral acid, so that the bile acid salts act as the salts of weak acids. In an example, dried ox-gall is saponified by boiling with caustic soda, the mass, diluted, and the excess soda carefully neutralized. The solution is filtered and acidulated, with vigorous stirring until it colours Congo paper blue. The bile acids, fatty acids, and coloured substances are thus precipitated as a pasty mass, which is stirred with a mixture of toluene and an aqueous solution of sodium acetate at 40-50‹ C. The bile acids are left as a crystalline powder which is separated, washed with toluene and warm water and dried in a vacuum at low temperature. The product is boiled with 1¢ times its weight of alcohol, when nearly pure cholic acid is obtained as a residue. It may be recrystallized from 4-5 times its weight of alcohol and decolorized with charcoal.

A printing plate 3 is clamped to a printing cylinder 1 through the engagement of each end between a substantially crescent-shaped rail 4 or 5, disposed in a bore 6 adjacent the peripheral surface of the cylinder, and a pair of axially aligned rollers 8 located between the rails. The rails are turnable in the bore, such that the edges 9, 10 are moved relative to each other, by the rollers 8 each of which is eccentrically mounted on a shaft 13 movable radially of the cylinder by hydraulically or pneumatically operated piston and cylinder means 15, 16. Plate-gripping movement of the rollers inwardlY of the cylinder is opposed by spring-loaded levers 11. To prevent unintentional plate release should the pressure medium fail each piston and cylinder may be arranged adjacent the surface of the cylinder diametrically opposite the associated rails, so that the centrifugal force acting on the piston always exerts a clamping effect on the rails whilst the cylinder is rotating. The cylinder shown is arranged to mount two printing plates and accordingly incorporates two bores, each of which houses associated clamping rails &c. and is angularly offset relative to the other around the periphery of the cylinder. The rollers 8 may be moved by a mechanical linkage instead of the piston and cylinder means shown.

A photo-cell is mounted on one face of a transparent insulating support and is encapsulated in a synthetic resinous material which may also enclose the insulating support or of which the support may form nearly all one side. Fig. 1 shows a section through an encapsulated cell comprising a photo-conductive layer 11 mounted on a glass plate 10 and bearing electrode layers 12 in the form of an interdigitated grid to which wires 13 are connected. The device is encapsulated in an epoxy-ethane resin for example "Araldite" type d (Registered Trade Mark). Fig. 2 shows the cell in a mould 14 supported on a glass backing plate before coating the resin. By supporting the cell on leads 13 the plate 15 may be wholly encapsulated. The conductive layer may be protected from resin or incident light by picein wax or beeswax. In large cells the coefficient of expansion of the resin may be lowered to that of the glass by the incorporation of powdered talc. The glass support may be coloured to act as a filter and, in the case of complete encapsulation, so may the resin. The sensitivity of the cell may be modified by pigmenting the resin because light is reflected from the inner walls of the encapsulation of the cell. The use of a white pigment, for example titanium dioxide, is suggested. The electrodes are formed by spraying a suspension of colloidal silver on to the photo-conductive layer through a mask and wires 13 are connected to the electrodes using conductive silver paste as an adhesive. Specification 820,547 is referred to.
