TWO:Gholson dropped in with something to be signed, and the General waved him to wait and hear. For Gholson, despite the sappy fetor of his mental temperament, had abilities that made him almost a private secretary to the General. Who, nevertheless, knew him thoroughly. When I had described Oliver's escape and would have hurried on to later details, General Austin raised a hand.

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:A sudden idiotic courage possessed her; she proposed to put things to the touch. The flickering firelight and her sense of convalescence inspired her. He had called her Helper, he had said a thousand things behind which meaning might lurk. It was her business, like that of every sensible girl who wants to be married, to show him that his shy priest-like advances met a slightly less shy welcome. A wave of calculating fatuousness combed over her."You say he remained three weeks on the back of that whale," said one of the listeners.
  • 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:What is it? he said."At the place where we reach the Great Wall there is a Chinese city called Chan-kia-kow; but it is known to the Russians as Kalgan. It is the frontier town of Mongolia, and the Russians have a great deal of commerce with it. It stands in a valley, and so high are the mountains around it that the sun does not rise until quite late in the forenoon. Doctor Bronson said there is a town somewhere in the Rocky[Pg 386] Mountains of America which is so shut in that the sun does not rise there until about eleven o'clock next day; and we thought it might possibly be a relative of Chan-kia-kow. There is an odd sort of population here, as the merchants who trade with the Russians are from all parts of China; and then there are Mongols from the Desert of Gobi, and a very fair number of real Russians.

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

THREE:Westward and westward went our travellers. From the Missouri River, the train crept gently up the slope of the Rocky Mountains, till it halted to take breath at the summit of the Pass, more than eight thousand feet above the level of the sea. Then, speeding on over the Laramie Plains, down into the great basin of Utah, winding through the green carpet of Echo Ca?on, skirting the shores of Great Salt Lake, shooting like a sunbeam over the wastes of the alkali desert, climbing the Sierra Nevada, darting through the snow-sheds and tunnels, descending the western slope to the level of the Pacific, it came to a halt at Oakland, on the shore of San Francisco Bay. The last morning of their journey our travellers were among the snows on the summit of the Sierras; at noon they were breathing the warm air of the lowlands of California, and before sundown they were looking out through the Golden Gate upon[Pg 46] the blue waters of the great Western ocean. Nowhere else in the world does the railway bring all the varieties of climate more closely together.While the Doctor and his companions were at table in the restaurant at Uyeno, they were surprised by the presence of an old acquaintance. Mr. A., or "The Mystery," who had been their fellow-passenger from San Francisco, suddenly entered the room, accompanied by two Japanese officials, with whom he was evidently on very friendly terms. They were talking in English, and the two natives seemed to be quite fluent in it, but they evidently preferred to say little in the presence of the strangers. Mr. A. was equally disinclined to talk, or even to make himself known, as he simply nodded to Doctor Bronson and the boys, and then sat down in a distant corner. When the waiter came, he said something to him in a low tone, and in a few minutes the proprietor appeared, and led the way to a private room, where the American and his Japanese friends would be entirely by themselves.
  • 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.
