Patent GB-574851-A (GB)
Title: Improvements in or relating to the manufacture of paper
IPC: D21H23/76
Filed: 1944-01-31
Abstract: Paper which is stabilized in respect of dimensional changes on wetting and on drying, and is of high wet-strength is prepared by adding to neutral or alkaline paper pulp, an aqueous, anionic emulsion of an etherified-diamide-aldehyde resin, in an organic solvent, which can be made insoluble by heat, acidifying the pulp to precipitate the resin on to the fibres, forming a web, and heating. The resin may be a mono- or di-etherified reaction product of an aldehyde, e.g. formaldehyde, with a diamido compound or its dimer or trimer, e.g. e.g. urea, thiourea, cyanamide, dicyanamide, guanidine, biuret or an aminotriazine, e.g. melamine, melam, melem, triethyl- or triphenyl triazine, ammeline or ammelide.  The reaction may be between the aldehyde and diamide in butanol or benzyl alcohol, or between the aldehyde and, e.g. an alkyl- or aryl-substituted urea. Preferably an etherified diamide-aldehyde resin, if solid, is dissolved in, e.g. toluol or xylol, to produce a viscous solution, and emulsified in a large quantity of water in a colloid mill, using a higher fatty acid or sulphonic acid salt of ammonia or of an alkali metal, or casein as emulsifying agent, with protective colloids and antiseptics such as chloro-phenols or salicylanilide if the emulsion is to be stored.  To give flexibility to the paper product, the resins may be mixed with an alkyd resin which may be modified by a fatty oil acid, in amounts up to 3 parts of alkyd resin to one of diamide resin.  Alkyl phthalates or aryl phosphates may be used as plasticizers.  The quantity of resin in the paper may be 1 to 5 per cent for towels &c. or 10 to 25 per cent for maps &c.  The acidic precipitant may be aluminium- or zinc sulphate, or ferric- or stannic chloride, or hydrochloric, phosphoric, sulphuric, citric, oxalic, acetic, or chloracetic acid.  One acidic substance may be used as a precipitant, and another as a hardener for the resin.  In an example, a diamide-formaldehyde-alcohol resin is prepared by reacting together 1 mol. of urea, 22 mols. of aqueous formaldehyde and 2 mols. of butanol, distilling off unreacted formaldehyde, water and butanol, and returning the alcohol to the reaction mass until the resin becomes soluble in aromatic hydrocarbons.  An emulsion is then made by mixing 67 parts of a solution of 60 per cent of urea-formaldehyde resin in butanol, with 0.8 per cent of oleic acid, and 4 parts of casein and 3.5 of ammonia in water to make 1000 parts, and in another example 26.5 parts of the same resin, as a 73 per cent solids solution, with 15.6 parts of a castor oil-modified glyceryl-phthalate resin in xylene is emulsified, also with casein, ammonia and water.

In the three-speed and reversing gear shown in Figs. 1, 2, and 4, the shaft 6 of the gear 11 is driven through a link belt 43 from a driving-shaft 1 about which the frame 5 pivots. The gear 11 is enmeshed with an idler 90, Fig. 1, for reversed driving. In order that it may be meshed with a step of the internal cone of gears on the driven shaft 2, the gear 11 is axially movable relatively to the frame 5. and to this end. the shaft 6 is splined within a sleeve 50 carrying the driven sprocket 7. A head 55 fast on the shaft 6 slides in a recess in the frame 5 and is connected bv a yoke pin 62 to a head 60 slidable on the control bar 70. The bar 70 is turned to cant the frame 5 by the sectors 74, 78 and is slid relatively to the sector 74 to change the plane of the gear 11. The frame 5 is held in gear positions by a tongue 81, Fig. 2, depending from the head 60 engaging in grooves 80<a>, 80<b>, 80<c> &c., Figs. 1 and 4, between upstanding lugs 80 on the frame. The tongue 81 has a depending heel 83 adapted to enter shallow guide, grooves 85, Fig. 1, on the frame. A spring 73 allows the head 60 and gear 11 to follow theinto-mesh sliding of the bar 70 when the parts are in register. A simplified form shown in Figs. 5 and 6 yielding two speeds only is suitable for use as an auxiliary gear on a vehicle and may be placed between the torque tube 113 and differential housing 120 as shown. The support 5 for the shaft 6 of the movable gear 11 is an eccentric cylindrical member which slides bodily along with the gear sectors 74, 78 and control bar 70. The shaft 6 has a sliding splined connection 144 with the propeller or driving shaft 1, which connection allows sufficient universal motion. Gear positions are fixed by a stop 156 engaging notches. 155 of different depths in the frame 5. The gear 11 has a carefully made clutch end. The driven shaft 2 is supported in a flange.d " pilot " member 121.

Title: Improvements in and relating to films of resins or other plastic materials
IPC: B29C48/08
Filed: 1945-02-06
Abstract: A solution of a synthetic resin or other plastic material is cast upon a film-forming surface provided by a coating, on a flat base, of a resin in which is embodied 25-50 per cent of a solid material insoluble in the resin and of such size as to produce surface irregularities not extending more than 0.0006 inches beyond the maximum depression; the solvent is evaporated from the cast solution and the solid film obtained is removed from the casting surface.  The film obtained has one smooth, light-reflecting surface and one suede-like surface.  The insoluble solid material may be fibrous talc of fibre diameter 0.003 to 0.00005 inches and fibre length 0.0016 to 0.003 inches or finely divided glass fibre, or needle-shaped crystals of sodium carbonate having similar particle size.  The resin solution may be sprayed, painted, cast, or applied by dipping, to the surface of a cylinder or continuous belt and dried thereon to form the mat casting-surface.  Solutions of polyvinyl chloride; vinyl chloride copolymers with vinyl acetate, ethyl maleate, or vinylidene chloride; cellulose acetate, cellulose aceto-butyrate, or cellulose xanthate, may be used as film-forming solutions, and they may be cast upon a mat surface formed from polyvinyl alcohol, or other synthetic resin which is insoluble in benzene, butyl-acetate, or chlorinated hydrocarbons.  A polyvinyl alcohol plasticized with glycerine may be used for the casting-surface. In casting films of alcohol soluble resins such as polyvinyl alcohol or nylon, the casting-surface may be formed from polyvinyl chloride or a copolymer of vinyl chloride.  The films with the mat surfaces are useful in the production of envelopes or bags, cohesion between adjacent surfaces of the films being avoided. When such films are stacked in sheet form, the mat surfaces avoid sticking of adjacent sheets.
