Abstract: 400,472. Electric furnaces. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST. GOBAIN, CHAUNY, ET CIREY, 1<bis>, Place des Saussaies, Paris. Feb. 6, 1933, Nos. 3581 and 3582. Convention dates, Feb. 5, 1932 and Jan. 19, 1933. [Class 39 (iii).] Apparatus for making drawn or rolled vitreous products, such as rods, tubes, or sheets, comprises an electrically heated melting-chamber for fusing the material, means for supplying the chamber continuously with solid vitrefiable material, and drawing or rolling apparatus which extracts the fused material from the lower part of the chamber at the rate at which it is formed, the heating device utilizing electric current that does not traverse the fused mass of material. In the construction shown in Fig. 1, the fusion chamber 1 consists of a crucible open at the top and having a removable bottom 2 pierced with an opening 3 through which the fused material is drawn by means of drawing-apparatus 5. The crucible is supplied with vitrefiable material, such as quartz grains, by means of a feeder 61, a distributor 65 being provided to spread the material evenly. The crucible cover 8 has lateral apertures through which electrodes 11 project to form an arc 10 for heating the material. The crucible is also heated by a surrounding resistor 12 consisting of a graphite helix screwed into carbon terminal blocks 20, 21. In a modified construction suitable for making plates or sheets of the material, the crucible consists of a trough formed of two inclined plane walls, and means are provided for moving the feeding-device along the trough to distribute the material. In another construction, shown in Fig. 4, the fusing-chamber consists of a cylindrical wall 1 pierced in its upper part with inclined ducts 15 and surrounded by an electric resistor 12, a vertical tube 26 of graphite being disposed between the wall 1 and the resistor. Ducts 29 formed in the case of the wall 1 permit the escape of siliceous vapours which issue from the curcible through the ducts 15 and expand into the space between the wall 1 and the tube 26. A graphite plate 30 covers the space between the tube 26 and a surrounding box 22 which is filled with heat-insulating material 23. The melting-apparatus is surrounded by a receptacle 32 which serves as a hopper for the unfused material 7. In use, the fused material is drawn through an aperture 3 as a tube or rod 35, and the flow of fresh material from the hopper 32 into the crucible maintains the supply of fused material. A mandrel 34 which projects into the crucible co-operates with the aperture 3 to determine the size of the drawn tube 35. Air may be blown through the mandrel to maintain the bore of the tube as it is drawn.

Title: Improvements in or relating to the manufacture of filaments, threads, ribbons, and the like materials comprising cellulose acetate or other organic esters of cellulose and of fabrics containing such materials
IPC: D06M11/38
Filed: 1933-02-14
Abstract: Filaments, threads, ribbons, fabrics, and like materials of or containing organic esters of cellulose are treated first with a hygroscopic substance or a substance capable of forming a viscous solution with water, and then while they still contain this substance, an aqueous saponifying agent is applied and the materials are immediately dried by heat so as to effect rapid saponification. Sodium acetate, silicate, oleate, palmitate, and stearate, di- and polyhydric alcohols, and water-soluble methyl cellulose and oxyalkyl celluloses are examples of substances applied to the materials prior to the saponifying agent.  The saponifying agent may be caustic soda or potash or a weaker agent such as baryta or lime, or a mixture of strong and weak reagents. Oils, soaps, and dyestuffs may be present in the saponifying medium.  The materials may be impregnated with the saponifying medium or the preliminary substance by bath or padding treatment and they may be in warp formation.  They may be treated subsequently to a stretching operation and they are preferably wound with little or no tension so that contraction may occur. The saponification may be partial or complete.  In an example, a fabric or warp of cellulose acetate is passed through a strong solution of sodium acetate and dried over hot rollers.  It is then passed through dilute caustic soda and again dried over hot rollers.  The caustic soda solution may be applied by a padding mangle.  Specifications 277,089, 316,521, 318,468, 323,790, [all in Class 2 (ii)], 370,430, 371,461, 400,996, 402,106, and 403,071 are referred to.
