TWO:Arthur could hardly control an eager curiosity to know what the thing was, round and shiny, that looked like a sort of halo at the back of the Clockwork man's head. He kept on dodging from one side to the other in an effort to see it clearly.Despite his fifty years, and the hard dry business atmosphere of his life, there was something amazingly boyish in the inward agitation{156} in which Keeling, arriving ten minutes before his time at his office next morning, awaited Norahs coming. His midnight excursion, dictated by some imperative necessity from within had, even if it was not a new stage in his emotional history, revealed a chapter already written but not yet read by him. He expected too, quite irrationally, that some corresponding illumination must have come to the girl, that she, like himself, must have progressed along a similar stage. He pictured himself telling her how he had left his house in order to have the satisfaction of seeing her lit window; he had a humorous word to say about the state of his dress shoes (in place of which he must not forget to order a pair from the boot and shoe department this morning). He could see her smile with eyes and mouth in answer to his youthful confession, as she always smiled when, as often happened now, some small mutual understanding flitted to and fro between them, and could easily imagine the tone of her reply, Oh, but how dreadfully foolish of you, Mr Keeling. You want to be laid up too, like Charles. She would not say more than that, but there would be that glimmer of comprehension, of acceptance, that showed she had some share in the adventure, that she allowed it, looked on it with the kind eye of a friend.

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:We are whitened by frost, we are chilled by the breeze
  • 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:"No, I would not!" But I had to yield. My dream was that our General had told me a fable. It was of a young rat, which seeing a cockerel, whose tail was scarcely longer than his own, leap down into a barrel, gather some stray grains of corn and fly out again, was tempted to follow his example, but having got in, could only stay there. The boys furnished the moral; it was not complimentary.

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

THREE:Upon whatever fundamental scheme we perseveringly concentrate our powers, upon whatever main road of occupation we take life's journey,--art, politics, commerce, science,--if only we will take its upper fork as often as the road divides, then will that road itself, and not necessarily any cross-road, lead us to the noblest, truest plane of convictions, affections, aspirations. Such a frame of mind may be quite without religiosity, as unconscious as health; but the proof of its religious reality will be that, as if it were a lighthouse light and we its keeper, everybody else, or at any rate everybody out on the deep, will see it plainer than we. Such is the gist of what this young man was saying to me, when our speculations were brought to an end by our overtaking a man well mounted, and a woman whose rough-gaited was followed by a colt.
  • 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.
