TWO:"Can't we make them think our men are here?" I suggested. "Couldn't I go back to where this fence crosses the gully and let them see me opening a gap in it?"A DEADLY FALL. A DEADLY FALL.

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:The other flapped an ear. Arthur hastened away. Nothing was worth while risking an exhibition in public such as he had witnessed in comparative seclusion. He supposed there was something about the Clockwork man really phenomenal, something that was beyond his own rather limited powers of comprehension. Perhaps cleverer people than himself might understand what was the matter with this queer being. He couldn'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:"Well, Smith, on his suggestion approved by Major Harper, I have detailed another clerk to the Major."

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

THREE:Allingham passed a hand across his forehead. "It all seems so feasible," he remarked, "once you grasp the mechanism. But what I don't understand"
  • 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:He had visions of a room full of golden brown beard. It was the most appalling thing he had ever witnessed, and there was no trickery about it. The beard had actually grown before his eyes, and it had now reached to the second button of the Clockwork man's waistcoat. And, at any moment, Mrs. Masters might return!I bent low, ran a few steps, cocking my revolver as I went. Then I rose, peeped, bent again, ran, rose, peeped, waited a few seconds behind the catalpa, and without rising peeped once more. Here he came! He was an officer. His uniform was torn and one whole side of him showed he had at some earlier hour ridden through a hedge and fallen from his horse. On he came! nearer--nearer--oh, what a giant! Quickly, warily, he crouched under the fence where it hung low across the gully, and half through it in that huddled posture he found my revolver between his astonished eyes. I did not yell at him, for I did not want the men he had escaped from to come and take him from me; yet when I said, "Halt, or you die!" the four ladies heard me much too plainly. For, frankly, I said more and worse. I felt my slenderness, my beardless youth, my rags, and his daring, and to offset them all in a bunch, I--I cursed him. I let go only one big damn and I've never spoken one since, though I've done many a worse thing, of course. I protest it was my modesty prompted it then.
