Title: An improved process for winding film on to reels
Inventor: MANN GEORGE HENRY
IPC: G03B21/32
Filed: 1949-05-09
Abstract: A process for winding a film, extruded with thickened margins, on to a cylindrical reel rotated by frictional contact of the film on the reel with a driving roll, is characterized in that the margins of the film are trimmed before winding to such an extent that the resultant edges of the film are not more than 75 per cent thicker than the centre of the film.  The driving roll then contacts the roll being wound only at its edges, whereby the number of creases and other deformities included in the roll of film is reduced.  The process is especially applicable to thin wide films, especially films produced from rubber and synthetic linear polymers.  According to the Provisional Specification, the desired contact between the film and driving roll may be achieved by extruding the film through an orifice having dimensions such that the edges of the film are of the necessary increased thickness, or the winding reel may have built-up ends.  Alternatively, the film may be passed through calender rolls which suitably reduce the thickness of the margins, or film of uniform thickness may be wound up with separate marginal strips of the required thickness.

Title: Improvements in or relating to cellulose derivative emulsions
IPC: C09D101/18
Filed: 1939-04-26
Abstract: 528,069. Emulsions. DU PONT DE NEMOURS & CO., E.I., DREYLING, A., and LEWERS, W. W. April 26, 1939, No. 12550. [Class 1 (i)] [Also in Group IV] A stiff cellulose derivative colloid mass is emulsified in an aqueous medium containing gum ghatti in dispersed form whereby a stable paste-like " oil-in-water" emulsion having a high content of film-forming ingredient is obtained. Preferably the aqueous medium also contains an emulsifying agent of the polar type. Mixing may be effected at relatively low speed. In an example, cellulose nitrate, water, blown castor-oil, butyl acetate, amyl alcohol, and shellac, are kneaded until the mass becomes smooth and free from undissolved material. To this mass there is added, while still kneading, a homogeneous dispersion of water-soluble gum ghatti, sodium benzoate, isopropyl naphthalene, sodium sulphonate and water. Alternatively the first mass may be added to the second composition. Kneading is continued till emulsification is completed. A solution of ethylene glycol monobutyl ether in water is then mixed with the emulsion. The glycol compound acts as a plasticizer for the gum when the emulsion is subjected to freezing conditions. It also assists the polar type emulsifying agent in lowering the interfacial tension. The cellulose nitrate may be utilized in water-wet state. In another example, cellulose nitrate is mixed with water, castor oil, isobutyl acetate, isobutyl alcohol, and tricresyl phosphate. The solution is then emulsified with a solution of gum ghatti, sodium benzoate, isopropyl naphthalene sodium sulphonate, toluol, and water. The emulsion is mixed with ethylene glycol monobutyl ether. Other compositions specified contain ester gum, sodium lauryl sulphate, propyl alcohol, ethyl alcohol, polyvinyl alcohol, xylol, highflash naphtha, or cyclic aliphatic compounds from asphaltic crude oils. Other emulsifying agents which may be present include Turkey red oil, alkali phthalates or sulphates of " Lorol " (Registered Trade Mark), sodium oleate, and ammonium ricinoleate. The emulsions so formed may be used for coating the backs of rugs or carpets, e.g. by spraying, brushing, or spreading methods. They may be used for coating or impregnating paper, textiles, fabrics, cloth, wood, or metal surfaces. They may be used as adhesives which function by evaporation of volatile constituents or by the action of heat. Specification 477,997 is referred to.
