Title: Improvements in or relating to lehrs for annealing glassware
IPC: C03B25/06
Filed: 1928-02-20
Abstract: 314,101. British Hartford-Fairmont Syndicate, Ltd., (Hartford-Empire Co.). Feb. 20, 1928. Glass-annealing leers.-In a continuous glass-annealing leer heating- gases are admitted to a longitudinal flue at some distance from the entrance end of the leer and are caused to flow in opposite directions, those flowing towards the entrance end producing a zone of gradually increasing temperature extending to the point of introduction of the gases, and those flowing in the opposite direction serving to control the cooling. The leer shown has upper and lower flues 5, 29 to which gases are supplied by combustion chambers 7, 30 respectively, the chamber 7 being situated nearer the entrance end of the leer than the upper one. Air for controlling the rate of cooling may be admitted to the flues through damper-controlled openings 21, 37, and the heating and cooling gases are exhausted by a fan 20 through damper-controlled conduits 15, 35, at the entrance end, and 22, 40 in the cooling-section. The openings 21 are so spaced or proportioned that a uniform damper setting will produce a constant temperature drop per unit length. Both upper and lower flues are in communication with the atmosphere at the exit end of the tunnel, so that the final cooling is effected by cold air only, the upper flue being stopped by a partition 38, which separates the air and heating-gas sections of the flue. The combustion chamber 30 is fired by burners 31, which are spaced to provide an even flame distribution. The leer shown, which is more particularly adapted for fusing enamel on glassware, and subsequently annealing it, provides a zone of gradually increasing temperature extending to the inlet 6, a zone in which the maximum temperature is maintained, for allowing the colour to fuse and mature, extending therefrom to the end of the combustion chamber 30, and a subsequent cooling zone of gradually decreasing temperature. Specification 250,201 is referred to.

Title: Improvements in or relating to the preparation of cellulose ethers
IPC: C08B11/12
Filed: 1939-02-27
Abstract: 525,739. Cellulose ethers ; treating textiles with liquids. WALLACH, R. Feb. 27, 1939, No. 6463. [Classes 2 (ii) and 15 (ii)] Cellulose ether compositions are obtained by subjecting loose jute fibres to the action of etherifying agents in the presence of alkali, the temperature of reaction and the concentration of the reagents being controlled so that products capable of being dissolved in water or aqueous alkali solutions are obtained. The reaction mixtures are diluted with water or aqueous alkali without separating unreacted portions of the fibres, to produce solutions of cellulose ethers containing undissolved fibres and which are suitable for use as sizes, coating or impregnating compositions for textiles or paper. The products are particularly suitable for impregnating or coating jute fabrics for use as Wrappers, bags, or packing material. The treatment binds the loose fibres and lays the nap. The cellulose ether solution may be mixed with cellulose ethers obtained from cotton, cellulose hydrate, oxy-cellulose, or 'other cellulosic material. It may be mixed with resins, gums, rubber latex, casein, gelatine, or other sizing, finishing, and adhesive materials. The cellulose ethers produced may be soluble in water or alkali solutions at room temperature or may become soluble after cooling the mixture until ice crystals appear and then allowing the temperature to rise. The jute used for etherification may be waste fibres obtained in the manufacture of jute-fabrics. After the treated jute fabrics or articles made therefrom are no longer fit for use they may be cut up and employed in the manufacture of rugs, upholstery, and other textiles, The alkali used in the etherification may be caustic soda or potash, or an aliphatic amine or quaternary ammonium base. Sodium carbonate may be present in addition to the caustic alkali. The etherifying agent may be dimethyl or diethyl sulphate, or ethyl hydrogen sulphate, or ethylene chlorhydrogen sulphate, or ethylene chlorhydrin, epichlorhydrin, glyceryl chlorhydrin, chloracetic or chlor-propionic acid. For water-solubility the quantity of etherifying agent is sufficient to introduce more than one ether group per cellulose unit but for alkali-soluble products the quantity is somewhat less. Catalysts such as copper, iron, or nickel salts may be present during the reaction. Neutral salts such as sodium chloride or potassium sulphate may also be present. The reaction mass may be aged in presence of alkali so as to reduce the viscosity properties of the product. For treating textiles, the materials may first be wetted out with water or an aqueous solution of an acid, then sprayed, dipped, padded, or back-filled with an alkali solution of the cellulose ether, the excess solution being removed by a doctor blade. The treated fabric is passed into an acid bath wherein the cellulose ether is fully coagulated. Specification 515,855 is referred to.
