TWO:But all this time the popular belief in omens had continued unaffected, and had apparently even increased. The peculiar Greek feeling known as Deisidaimonia is first satirised by Theophrastus, who defines it as cowardice with regard to the gods, and gives several amusing instances of the anxiety occasioned by its presenceall connected with the interpretation of omenssuch as Aristophanes could hardly have failed to notice had they been usual in his time. Nor were such fancies confined to the ignorant classes. Although the Stoics cannot be accused of Deisidaimonia, they gave their powerful sanction to the belief in divination, as has been already mentioned in our account of their philosophy. It223 would seem that whatever authority the great oracular centres had lost was simply handed over to lower and more popular forms of the same superstition.

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:It struck him that he was coolly analytical while his wife was reading the love-letter (if that bald statement of fact could be called a love-letter) of another man, and telling him frankly that she returned the man's love. Why could not he have had love, he who had done so much for her? There was always the subconsciousness of that sacrifice. He had magnified it a little, too, and it is difficult to be altogether lovable when one's mental attitude is "see what a good boy am I." But he had never reflected upon that. He went on telling himself whatin all justice to himhe had never thrown up to her, that his life had been one long devotion to her; rather as a principle than as a personality, to be sure, but then And yet she loved the fellow whom she had not known twenty-four hours in alla private, a government scout, unnoticeably below her in station. In station, to be sure; but not in birth, after all. It was that again. He was always brought up face to face with her birth. He tried to reason it down, for the hundredth time. It was not her fault, and he had taken her knowingly, chancing that and the consequences of her not loving him. And these were the consequences: that she was sitting rigid before him, staring straight ahead with the pale eyes of suffering, and breathing through trembling lips.Somebodys knocking, Dick gasped.
  • 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:

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

THREE:I dont see what could happendid anything happen?
  • 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.
