TWO:Bright, black eyes peered down from crevasses and branches. An Apache lurked behind every boulder and trunk. But only the squaws and the children and twenty-six bucks in war toilet, naked from shoulder to waist, painted with blood and mescal, rings in their noses, and heads caked thick with mud, came down to the conference.Nevertheless she decided that it might be best to tell her husband, and she did so as they sat together by the fire after the moon had risen into the small stretch of sky above the mountain peaks. They had bought a live sheep that day from a Mexican herder who had passed along the road, and they were now cutting ribs from the carcass that hung from the branch of a near-by tree, and broiling them on the coals. Felipa finished an unimpassioned account of the afternoon's happenings and of Alchesay's advice, and Landor did not answer at once. He sat thinking. Of a sudden there was a rustle and a step among the pines, and from behind a big rock a figure came out into the half shadow. Felipa was on her feet with a spring, and Landor scrambled up almost as quickly.

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:They laid Landor upon the ground, in the same patch of shade he had glanced at in coming by not five [Pg 281]minutes before. His glazed eyes stared back at the sky. There was nothing to be done for him. But Cairness was alive. They washed the blood from his face with water out of the canteens, and bound his head with a wet handkerchief. And presently he came back to consciousness and saw Landor stretched there, with the bluing hole in his brow, and the quiet there is no mistaking on his sternly weary face. And he turned back his head and lay as ashy and almost as still as the dead man, with a look on his own face more terrible than that of any death.He went the next day but one, riding out of the post at daylight. And he saw Felipa once more. She was standing by the creek, drawing an arrow from her quiver and fitting it to her bow. Then she poised the[Pg 32] toe of her left foot lightly upon the ground, bent back, and drew the bow almost to a semicircle. The arrow flew straight up into the shimmering air, straight through the body of a little jay, which came whirling, spinning down among the trees. Felipa gave a quick leap of delight at having made such a shot, then she darted down in search of the bird. And Cairness rode on.
  • 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:Cairness knew that it was true, too true to refute.

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

THREE:Felipa had discarded, long since, the short skirt and moccasins of her girlhood, and had displayed no inconsiderable aptitude in the matter of fashions; but she was given to looseness of draperies and a carelessness of attire in her own home that the picturesqueness of her beauty alone only saved from slatternliness. There was one manifestation of ill taste which she did not give, however, one common enough with the wives of most of the officers. She was never to be found running about the post, or sitting upon the porches, with her husband's cape around her shoulders and his forage-cap over her eyes. Her instinct for the becoming was unfailing. This was a satisfaction to Landor. But it was a secret grievance that she was most contented when in her riding habit, tearing foolhardily over the country.
  • 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:Then he stopped, with every muscle drawn, for he had seen in her answering, unflinching gaze that he was losing her, surely, irrevocably losing her. He let her go, almost throwing her away, and she caught hold of a ledge of rock to steady herself. He picked up the heavy quirt and held it out to her, with a shaking hand, shame-faced, and defiant, too.
