TWO:Felipa felt something of this, and it lessened the vague burden of self-reproach she had been carrying. She was almost cheerful when she got back to the post. Through the last breakfast, which the Elltons took for granted must be a sad one, and conscientiously did their best to make so, she had some difficulty in keeping down to their depression.[Pg 69]

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:Lawton produced a brace of revolvers.
  • 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:It was failure, flat failure. The officers knew it, and the general knew it. It was the indefinite prolongation of the troubles. It was the ignominious refutation of all his boasts—boasts based not so much upon trust in himself, as on belief in the nature of the Apache, whose stanch champion he had always been.

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

THREE:His own was instantly as cold. "I supposed you had quite forgotten all that," he said.
  • 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:"You speak with the utmost fluency, my daughter,"[Pg 47] he had commended, and she had explained that she found expression more easy in French.But he knew that she did not love him. She was grateful. It was sometimes an Apache trait. He realized that it was his curse and hers that he could not for an instant forget the strain. He read her character by it, half unconsciously. He saw it in her honesty, her sinewy grace, her features, her fearlessness, her kindness with children,—they were all Apache characteristics; and they were all repellent. From his youth on, he had associated the race with cruelty and every ghastly sight he had come upon, on the plains and in the mountains. It was a prejudice with more than the force of a heritage. He went on with his study of her, as she sat there. He was always studying her.[Pg 54] But he could not decide whether it was that she lacked sensitiveness and was really not greatly disturbed, or a savage sort of pride in concealing emotions.
