TWO:"The streets are not at all dirty, and in this respect are vastly different from those of any other city we have seen in China. The authorities evidently pay some attention to keeping them clean and preventing the accumulation of dirt. The fronts of many shops are fully open to the street, and the merchants know how to arrange their wares in the most tempting manner. You see lots of pretty things, and are constantly tempted to buy, and it was very well for us that we agreed not to buy anything till the last day, which we were to devote to shopping."I see them lying in the pit," explained Tom, "they must 'ave dropped off 'is 'ead as he lay there. Of course, 'e 'adn't fallen very far, otherwise 'is legs wouldn't ave been sticking up. It 'aint very steep just there, and 'is 'ead must 'ave caught in a bit of furze. But the 'at and wig 'ad rolled down to the bottom. After 'e'd gone I climbed down and picked them up."

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:But the command to fire did not come; suddenly there was a drumming of hoofs, then their abrupt stoppage, and the voice of a vigilant commander called, "Attention!"
  • 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:"Anyway, it's the fashion," the other growled hoarsely. "I ought to know because I used to be one of them before the accursed drink--but that is another story. Ever heard of the Countess Lalage?"

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

THREE:That was Gregg's dimly conceived theory about the mystery, although, of course, he read into the interpretation a good deal of his own speculations. His imagination seized upon the clock as the possible symbol of a new counterpoint in human affairs. In his mind he saw man growing through the ages, until at last, by the aid of this mechanism, he was able to roll back the skies and reveal the vast other worlds that lay beyond, the unthinkable mysteries that lurked between the stars, all that had been sealed up in the limited brain of man since creation. From that extreme postulate it would be necessary to work backward, until some reasonable hypothesis could be found to explain the working[Pg 111] of the clock mechanism. That difficulty, even, might be overcome if only an opportunity occurred to examine this strange being from the future, or if he could be prevailed upon to explain matters himself.Then shall I go down to your house now, and get on with my business? she 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:And the new wing, on your guarantee, is urgently needed? asked Keeling.You are very mysterious, dear, she said. You seem to forget that I am your mother. And if you tell me that I must speak to nobody about it yet, you may be sure I shall not do so without{225} your leave. I was always famous for my ability to keep a secret. Why, not so long ago your father told me something which I am sure will make Mrs Fyson turn quite green with odious jealousy when she hears it, and I have not breathed a word to anybody. Not a word. So dont be so mysterious, dear; I remember going to tell Mamma the moment your father spoke to me, and it was in the garden behind Mammas house; I could show you the very place, if you dont believe me.
