TWO:Of lacquer-ware, of all kinds and prices, there was literally no end. There were trays and little boxes which could be had for a shilling or two, and there were cabinets and work-stands with numerous drawers and sliding panels curiously contrived, that a hundred dollars, or even five hundred, would not buy. Between these two figures there was a wide range, so that the most modest purse could be gratified as well as the most plethoric one. Frank found that the dealers did not put their best goods where they could be most readily seen. The front of a shop contained only the most ordinary things; and if you wanted to look at the better articles, it was necessary to say so. When the merchant knew what his customer wanted, he led the way to the rear store, or perhaps to an upper floor, where the best goods were kept. It was necessary to walk very carefully in these shops, as they were very densely crowded with goods, and the least incaution might result in overthrowing some of the brittle articles. A clumsy visitor in one of these establishments a few days before Frank called there had broken a vase valued at fifty dollars, and while stooping to pick up the fragments he knocked down another worth nearly half that amount. He paid for the damage, and in future declined to go around loosely in a Japanese store.

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:Yes, and me the Lady Mayoress, she said. Why, Im ever so nervous even now in the thinking of all the grand parties I shall have to give. And the hospital will be finished next year too, and what a to-do we shall have over that. And what do you say now, Mamma, to having your cup of coffee in my boudoir quietly with Alice and me, leaving the gentlemen to have a cigarette.
  • 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:"They held out for two days, and during all that time hardly a man of us slept more than a few minutes at a stretch. Many of the coolies were suffering terribly with thirst and hunger, and they asked to have their wants supplied while they were making negotiations for peace. The captain refused anything but the most unconditional surrender, and the only concession he would grant was to have the dead bodies passed up to be thrown overboard. Of course the coolies were very glad of this, as they were suffering from the fearful condition of the narrow space where they were confined. When this work was completed, they asked for half[Pg 398] an hour's time to make a proposal for surrender, which was allowed them.Late that evening the Doctor returned from a confinement case, which had taken him to one of the outlying villages near Great Wymering. The engine was grinding and straining as the car slowly ascended a steep incline that led into the town; and the Doctor leaned forward in the seat, both hands gripping the wheel, and his eyes peering through the wind-screen at the stretch of well-lit road ahead of him.

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

THREE:"I've thought of all that," he droned.
  • 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:The Doctor explained that the hole was a cask set in the ground, and that it probably contained liquid manure. The Japanese use it for enriching their fields. They keep it in these holes, covered with a slight roof to prevent its evaporation as much as possible, and they spread it around where wanted by means of buckets. The great drawback to a walk in a Japanese field is the frequency of the manure deposits, as the odor arising from them is anything but agreeable. Particularly is this so in the early part of the season, when the young plants require a great deal of attention and nourishment. A nose at such times is an organ of great inconvenience.The mystery was soon solved. The river was neither wide nor deep, and the men they saw waiting by the bank were porters who carried people across, and also carried merchandise. The stream was said to rise very rapidly, and owing to the nature of the bottom it was difficult to maintain a bridge there for any length of time. The porters took the party across very speedily; they carried the servants by what the boys called "pick-a-back," while Doctor Bronson and the boys were borne on chairs resting on poles, with six men to each chair. Some horses belonging to another party were led through the river at the same time, and evidently were not pleased with the bath they were receiving.
