Title: Improvements in or relating to the production of aqueous dispersions of nitrocellulose
IPC: C09D101/18
Filed: 1935-06-12
Abstract: Aqueous dispersions of nitrocellulose having a latex-like appearance and suitable for the manufacture of films, for impregnating textiles and paper, and as lacquers and coating compositions, are made by preparing a viscous solution of nitrocellulose in acetic acid or other aliphatic carboxylic acid miscible with water, the solution containing a proportion of glue, gelatine or other amino-acid colloid soluble in acetic acid, and then adding water or a dilute acetic acid &c. solution gradually with agitation to the viscous solution until there is formed a milky liquid.  The nitrocellulose solution may be heated before the precipitation, and a plasticizing or softening agent for nitrocellulose may be included in the viscous solution, the plasticizing &c. agent being precipitated with the nitrocellulose. In the further working-up of the milky liquid, the bulk of the acetic acid is removed by flocculating the precipitate, followed by separation of the supernatant liquor and centrifuging; alternatively, dialysis or electrophoresis may be used; the concentrate may be taken up in water &c. and again concentrated, and a proportion of glue &c. may be added to the washing waters. The resulting paste may be redispersed in water conveniently assisted by the colloid mill, the dispersing liquid being for example dilute ammonia or containing a small proportion of the glue &c. and of a water-soluble organic solvent for the nitrocellulose.

[Also in Group XI] Welding.-A method of manufacturing seamwelded metal pipe from metal strip comprises pre-heating the strip to a temperature sufficient for hot-forming it into a tube but insufficient for welding, electrically heating the longitudinal edges of the pre-heated strip to the welding temperature and then pressure welding the edges to form a longitudinal seam. A metal strip 10 of rectangular cross-section is fed into a preheating furnace 13 by pairs of driving rollers 11 and 12 where it is heated to the forming temperature, e.g. 1500‹ F. for low carbon steel. A photo-electric cell 14 regulates the furnace temperature and the speed of the strip. The pre-heated strip then passes into a high frequency induction type heater 15 (see Group XI) which heats the two longitudinal edges of the strip to welding temperature, e.g. 2400‹ F. for low carbon steel. The heater may be water cooled to reduce its working temperature and the power output of the heater is controlled by a photo-electric cell 20. The strip then passes through a tube forming machine 21 which rolls or shapes the pre-heated strip to the desired tubular shape and presses together the highly heated opposed longitudinal edges to form a welded seam. The pre-heated strips may be formed into a tubular shape with its edges in closely spaced opposed relationship before the edges are heated to the welding temperature and finally welded together.
