TWO:After she had done that she stood hesitating for just a moment before she threw off all restraint with a toss of her head, and strapped about her waist a leather belt from which there hung a bowie knife and her pistol in its holster. Then slipping on her moccasins, she glided into the darkness. She took the way in the rear of the quarters, skirting the post and making with swift, soundless tread for the river. Her eyes gleamed from under her straight, black brows as she peered about her in quick, darting glances.

Membrane separation type solvent dehydration system

Great attention is recently being paid to global environmental issues, and it is now conceivable that companies will need to treat used solvents themselves. In consideration of this kind of social issue, we have developed a “membrane separation type solvent dehydration system,” which uses a polyimide membrane with superior dehydration properties developed by Ube Industries, Ltd. in combination with our own distillation and concentration technology that has resulted in solvents being more easily recovered.

THREE:Some thirty miles to the southeast was the Mescalero Indian Agency. Landor had consented with the worst possible grace to take her there sometime when the[Pg 184] road should be passable and safe. She had openly resented his disinclination, though she usually appeared not to notice it. "It is very natural I should want to see the place where I was born," she had said, "and I think we should both be more comfortable if you would not persist in being so ashamed of it."Presently she began again, "Well, he wasn't in it at all. Stone wasn't."
  • 1Under the distillation system, even in case of azeotropic solvent compositions, this system which remove water vapor by the polyimide membrane will easily dehydrate.
  • 2In comparison with the distillation system, it significantly saves on use of steam.
  • 3Dehydration can be performed through merely supplying evaporated vapor to the membrane module and maintaining the differential pressure between the permeable side and the impermeable side.
  • 4Solvent purity of 99.9% or more can be achieved by carrying out dehydration with a polyimide membrane only.
  • 5The polyimide membrane has superior heat and solvent resistance. Therefore, the vapor permeation system reduces contamination of the membrane and thus extends its life.
THREE:Landor's fear of leaving the settlements unguarded grew. "We will get up among these mountains and be delayed, and we are in no condition whatever to travel, anyway," he told Brewster, as the advance[Pg 119] guard halted again, and Landor, with curses in his heart but a civil tongue withal, trotted up to them."Let go your stirrup!" cried Cairness, in her ear; and as she kicked her foot loose, he leaned far from the saddle and threw his arm around her, swinging her up in front of him across the McLellan pommel, and driving the spurs into his horse's belly. It had the advantage of her horse in that it was an Indian animal, sure of foot as a burro, and much quicker. With one dash it was up the hillside, while the other rolled over and over, down into the torrent of the cloud burst.

The aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.

THREE:There is a majesty about the mountains of the desolate regions which is not in those of more green and fertile lands. Loneliness and endurance are written deep in their clefts and ca?ons and precipices. In the long season of the sun, they look unshrinking back to the glaring sky, with a stern defiance. It is as the very wrath of God, but they will not melt before it. In the season of the rains, black clouds hang low upon them, guarding their sullen gloom. But just as in the sternest heart is here and there a spot of gentleness, so in these forbidding fastnesses there are bits of verdure and soft beauty too.
  • 1 Recovery of the detergent solvent Recovery of the cleaning solvent such as electronic parts industry, precision instrument industry.
  • 2Solvent recovery and the refinement Solvent recovery and the refinement such as chemical industry, an industry of medical supplies, food industry, the fermentation industry.
THREE:As for the Kirby affair, there had been no hint of treachery in the published or verbal accounts of it. The ranch hands who had escaped had told a plain enough tale of having fled at the approach of the Indians, vainly imploring the Kirbys to do the same. It[Pg 166] seemed that the most they could be accused of was cowardice. It had all been set forth in the papers with much circumstance and detail. But Cairness doubted. He remembered their dogged ugliness, and that of the raw-boned Texan woman.
