Abstract: The heat-resistance of saponified stretched cellulose ester filamentary material is improved by incorporating therein a carboxylic acid salt of an alkaline-earth metal, i.e. of calcium, barium, strontium or magnesium.  The filamentary material preferably contains 0,5-20 milligram atoms of alkaline-earth metal per 100 grams of filamentary material.  Salts, e.g. calcium lactate, strontium lactate and strontium salicylate, which are water-soluble and ionizable may be applied as aqueous solutions to the filamentary material by dipping or spraying followed by drying, the tensile strength of the filamentary material also being increased by the treatment.  Water-insoluble salts, e.g. calcium laurate, calcium undecylenate, calcium stearate and strontium caproate, may be applied as hot solutions in organic solvents or as aqueous emulsions, or may be formed in situ on the filamentary material by passing it through an aqueous solution of a water-soluble salt, e.g. sodium stearate, and then through an aqueous bath of a water soluble material reactive with said salt, e.g. calcium chloride.

Abstract: 117,271. Pointe, J. C. A. July 5, 1917, [Convention date]. Addition to 8381/13. Processes for reduction of grain; damping grain; processes of treating grain.-Relates to improvements in the process and apparatus described in the parent Specification for converting grain into paste or dough. The grain is first washed and then removed to a metal vessel containing water between 40 and 55‹ C., and maintained at that temperature by any suitable means, as by a water bath, kiln, or insulating jacket, for from 8 to 16 hours. When sufficiently softened, and the grain has absorbed from 65 to 70 per cent of its weight of water, it is transferred to the hopper 14, Fig. 3, of a pulping device, for conversion into paste or dough. From the hopper. the softened grain passes between adjustable rotating grooved metal rollers 15, 16, provided with a scraper 17, and thence to an endless screen or sieve of metal netting or perforated metal sheet 23 carried by two perforated drums 18, 19, and through which the pulp is caused to pass by means of a series of rubber or like rolls 24. The drums are carried on rollers 20 on the frame 21. The adhering husks are removed from the screen by rotary cylindrical brushes 25 or by scrapers, while the pulp is. removed from the interiors of the drums by scrapers 27, 28 and directed to two finishing cleaning screens 29, 30 situated within the drums. A rotary toothed cylinder 26 intermediate of the two drums removes from them any pasty matter left. The screens 29, 30 are of metal netting or of perforated sheet, and pass over a small grated drum 31 and a roll 32, on the former of which acts a stripper cylinder 33. Rolls 24' force the paste through the screens into the interiors of the small drums, from which the paste is removed by helical strippers 34, 35 and carried outwards into a suitable receiver. The pressure of the rolls 24, 24' may be varied as required by connecting each end of the axle of each roller to external levers 40, Fig. 5, operated by springs 41 controlled through screw-threaded rods 42 and worm gearing 43, 44.
