Filed: 1929-06-07
Abstract: 313,876. Badger & Sons Co., E. B., (Assignees of Hall, W. T.). June 18, 1928, [Convention date]. Hydrocarbons, d'istilling and cracking; distilling plant and processes.-The amount of vapour formed in the first distillation unit of a distilling or cracking system is controlled by withdrawing and heating a separated fraction of the material in a heater forming a subsequent part : of the distillation system and constituting the sole source of heat, and returning a part of the heated fraction to the unit. Liquid enters through a preheater 11, Fig. 1, and passes by a pipe 12 to a fractionating column 13 from which the lighter fraction is withdrawn by a pipe 15. The middle fraction mav be passed by a pipe 33 to a second column 21. The heavy fraction is drawn off by a pump 18 and heated in a pipe still 19. Part of this heated fraction passes by a pipe 20 to the column 21, and part by a pipe 40 to the column 13, the quantity being regulated by a valve 41 preferably controlled by a thermostatic device 43. A second thermostatic device 44 controls by a valve 46 the fuel supply to the pipe still 19. In the invention as applied to a cracking plant of the Dubbs' type, Fig. 2, the oil feed entering by a. pipe 50 is partially vaporized as it passes down a column 51 and the unvaporized residue is forced by a pump 53 through a pipe still 54 heated to cracking temperature. The hot oil is discharged into a combined vaporizer and reaction chamber 57 from which the light oils pass through a pressure reducing valve 59 to the column 51 and a condenser 63. A part of the heated oil from the pipe still 54 is returned to the column by an intermediate connection 70 through a valve 71 operated by a thermostatic device 72.

Title: Improvements in textiles containing cellulose derivatives
IPC: D06M11/38
Filed: 1931-06-18
Abstract: Filaments, threads, yarns, fabrics, and like materials made of or containing organic derivatives of cellulose are treated with a latent solvent and allowed to shrink.  The latent solvents contemplated are liquids which are swelling agents but not solvents, although convertible into solvents by the addition of a small proportion of another substance such as an alcohol. Methylene chloride, ethylene chloride, chloroform, tetrachlorethane, dichlorethylene, and ethyl acetate are suitable for treating materials of cellulose esters or ethers.  The yarns or fabrics may be sprayed, padded, or immersed in the shrinking agent or treated with its vapour.  Local application to obtain brocade effects may be achieved by printing or spraying if desired with the use of stencils.  The shrinking agent may be diluted with benzene, toluene, xylene, benzine, petrol, kerosine, carbon tetrachloride, trichlorethylene, or perchlorethylene.  If alcohols are used as diluents they must not be added in such proportions as to constitute a solvent mixture.  Cellulose acetate or other cellulose organic ester or ether filaments may be associated by twisting, knitting, or weaving, with filaments of cotton, regenerated cellulose, natural silk, wool, or other filaments not affected by the shrinking agent used so that upon treatment of the associated yarn or fabric, crepe, pebble, cockle, and other effects are obtained. Differential shrinkage may be obtained by applying the shrinking agent to yarns or fabrics containing cellulose esters or ethers of different types or obtained by different methods, such as dry and wet spun yarns.  The shrinking effect may be utilized to reduce the tendency of knitted fabrics to ladder, of warp knitted fabrics to split, and of woven fabrics to slip.  It may also be utilized to cause tensioning of umbrella fabrics on their frames.  Specifications 351,999 and 356,233 are referred to.
