Title: Treatment of textile fabrics with synthetic resins
IPC: D06M15/423
Filed: 1938-09-26
Abstract: 520,579. Coated fabrics. BARTLETT, R. G., LAWRIE, L. G., HILL, A., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 26, 1938, Nos. 28011/38 and 11419/39. [Class 140] [Also in Group IV] Textile fabrics of silk or natural or artificial cellulose fibres are rendered more resistant to penetration of fluids by coating them with a synthetic resinous composition comprising one or more modified polyhydric alcohol polybasic acid resins in which part of the polybasic acid is replaced by monobasic acids derived from non-drying oils, e.g., castor oil acids, in union with one or more urea-formaldehyde condensation products, or comprising one or more semidrying oil modified polyhydric alcohol polybasic acid resins together with a proportion of not more than 20 per cent. of one or more ureaformaldehyde condensation products. The resinous composition dissolved in a volatile solvent may be applied by spraying, spreading or immersion to one or both sides of the fabric. The solvent is volatilised at raised temperature and the fabric may be subjected to further heat treatment. The fabric may be treated repeatedly with the resinous composition. When a semidrying oil modified resin is used it may be selected from soya bean, sunflower, safflower, walnut, or poppy seed oil modified glyceryl phthalate resins and the proportion of oil is preferably 35-55 per cent. of the weight of the resin. The urea-formaldehyde compound may be a simple condensation product or one modified by an aliphatic alcohol containing four carbon atoms, or one obtained by alkaline condensation of formaldehyde with urea and a formaldehyde condensation product of a carbamic ester or monocarboxylic acid amide. The coated fabrics may be subjected to mechanical finishing treatments, or printed with a nitrocellulose lacquer, or a pigmenting composition. or they may be coated with shellac, or treated to produced " oiled silk " products. They may be subjected to softening treatments. The composition may be applied locally. Dyestuffs may be incorporated in the solvent, e.g., benzene, methyl alcohol, or a butyl alcohol, used for dissolving the resinous composition. The treatment may result in an increase in weight of the materials, up to 600 per cent. Silk fabric is treated with a solution of a product obtained by heating a mixture of dimethylol urea and a castor oil modified polyhydric alcohol-polybasic acid resin dissolved in glycol monomethyl ether, or with a solution containing a mixture of this product and a further quantity of the oilmodified resin. Rayon or muslin fabrics may be similarly treated. Silk fabric, regenerated cellulose fabric or cotton muslin fabric, is immersed in or printed with a solution containing ureaformaldehyde resin and a resin obtained by heating soya bean oil with glycerol, caustic soda, water, and phthalic anhydride.

Filed: 1977-07-06
Abstract: 1529546 Telecine apparatus ROBERT BOSCH GmbH 6 July 1977 [6 July 1976] 28284/77 Heading H4F In a telecine apparatus each frame of a continuously moving film is scanned during a single television field period by a scanning tube raster having the full number of lines of a complete television frame of two fields without interlace. The height:width ratio of the raster is half the normal ratio, and the line rate is double the normal rate. Alternate lines of the video signal resulting from the scanning of a film frame are passed to respective first and second stores. Each line in the first store is read at normal line rate to form a first television field, and then each line of the second store is read to form a second field interlaced with the first. Scanning of the film during alternate field periods is prevented. If the television field frequency is 60 Hz and the film frame frequency 24 frames per second the scanning raster must be displaced by one line between successive scans. No such displacement is necessary if the field frequency is 50 Hz and the film frame frequency 25 frames per second.
