Title: Punch-out film mount
IPC: G03B21/64
Filed: 1974-05-14
Abstract: 1425673 Transparency mounts BYERS PHOTO EQUIPMENT CO 14 May 1974 [13 July 1973] 21395/74 Heading G2X A transparency mount comprises two laminae 10, 12 hinged together to enclose the transparency between them, and having a central area defined by perforations or slits such that the said central area can be readily punched out to form a smaller mount. As shown, the mount is formed from an integral injection-moulded sheet of a plastics material, the laminae being hinged together at 14. Openings 16, 18 in the laminae form the picture aperture, the transparency being located in depressions 32, 34 which between them form a pocket. The laminae are secured together in the folded position by a number of posts 40 on one which fit into corresponding openings 42 in the other. A further set of posts 44 closer to the transparency aperture similarly fit into corresponding openings 46. A rounded projection 54 enters into an opening 56 and slightly distorts the transparency so locking it in position, and may also enable a frame number to be viewed. The central area is surrounded by a rectangular arrangement of slits 20, 22 whose ends are closely adjacent. Thus the central area can readily be punched out, forming a mount which is smaller than the original mount, although the transparency is still the same size. The construction thus enables the one mount to be adapted to two alternative sizes according to the type of projector being used.

Title: Improvements in the manufacture of artificial filaments, threads, yarns and the like
IPC: D01F2/28
Filed: 1932-08-06
Abstract: Artificial filaments, threads, yarns, ribbons and the like are obtained by extruding a solution of a cellulose ester or ether in a neutral solvent, mixture of solvents, or solvent mixture, into a coagulating medium containing a high concentration of the same solvent, mixture of solvents, or solvent mixture, together with a non-solvent, the solvent or at least one constituent of the mixture of solvents or solvent mixture having a boiling point not less than that of the non-solvent of the coagulating medium or being not more volatile than the non-solvent under the conditions obtaining.  The cellulose derivative may be cellulose acetate, formate, propionate, butyrate, or nitro-acetate, methyl, ethyl, or benzyl cellulose, or a cellulose ether ester.  The solvent may be glycol mono-acetate, methyl glycol mono-acetate, diacetone alcohol, ethyl lactate, diethyl tartrate, dioxane, methylene ethylene dioxide, or dioxane dicarbinol. The non-solvent of the coagulating bath may be water, alcohol, or a hydrocarbon.  Salts or sugars, or lubricants such as oils, may be added to the coagulating bath.  The lustre of the products is increased by raising the concentration of the solvent in the coagulating bath. A non-solvent in proportions up to that which just fails to cause precipitation may be added to the spinning solution. The products may be stretched continuously with production.  The products are freed from the coagulating liquid by washing with water, salt solutions, or solutions of solvents of lower concentration than those adhering to the products, or by evaporation.  In an example, cellulose acetate dissolved in dioxane is spun into a 50 per cent aqueous solution of dioxane and the bundle of filaments is passed under a guide and round a draw-roller.  The filaments pass to washing and drying devices and are then wound or twisted. Specifications 177,868, 179,234, [both in Class 2 (ii), Cellulose &c.], 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, 370,430, 375,423, 375,424, 378,858, 380,819, 391,480, and 401,679 are referred to.
