TWO:Youre naughty too, he said. This is play-time. And now theres something else I want to talk about. You ladies are the queens of your homes: dont you think you could persuade Mr Keeling not to think me the thin edge of the Pope, so to speak?"Just what I'm always telling my missus," reflected the constable.

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:The boys were all anxiety to take a walk through the streets of Yokohama, and could hardly wait for the Doctor to arrange matters with the hotel-keeper. In a little while everything was determined, and the party went out for a stroll. The Doctor led the way, and took them to the Japanese portion of the city, where they were soon in the midst of sights that were very curious to them. They stopped at several shops, and looked at a great variety of Japanese goods, but followed the advice of the Doctor in deferring their purchases to another time. Frank thought of the things he was to buy for his sister Mary, and also for Miss Effie; but as they were not to do any shopping on their first day in Japan, he did not see any occasion for opening the precious paper that Mary had confided to him previous to his departure.It was not only in matters of office work, of swift shorthand, of impeccable typewriting that she was of use to him. She guessed that he found in her a companionship that Mrs Keeling with her pearl-pendant and her propriety could not supply. Norah knew all about the pearl-pendant: Mrs Keeling had told her, as it wagged at her throat, that her husband had given it her on her birthday, and was it not handsome? It was tremendously handsome: there was no doubt whatever about that. But the pearl-pendant mattered to Norah exactly as much as did the cheque which she had just{197} been given. It mattered less, indeed: it did not express anything.
  • 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:ESTABLISHED OVER 2,000 YEARS.

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

THREE:The company was not a large one, and there was abundant room and abundant food for everybody. The captain was at the head of the table, and the purser at the foot, and between them were the various passengers in the seats which had been reserved for them by the steward. The passengers included an American consul on his way to his post in China, and an American missionary, bound for the same country. There were several merchants, interested in commercial matters between the United States and the Far East; two clerks, going out to appointments in China; two sea-captains, going to take command of ships; a doctor and a mining engineer in the service of the Japanese government; half a dozen "globe-trotters," or tourists; and a very mysterious and nondescript individual, whom we shall know more about as we proceed. The consul and the missionary were accompanied by their families. Their wives and daughters were the only ladies among the passengers, and, according to the usual custom on board steamers, they were seated next to the captain in the places of highest honor. Doctor Bronson and his young companions were seated near the purser, whom they found very amiable, and they had on the opposite side of the table the two sea-captains already mentioned.
  • 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:"But you don't get all the whales you see, by a long shot. Many a whale gets away before you can fasten to him, and many another whale, after you have laid on and fastened, will escape you. He sinks, and tears the iron loose; he runs away to windward ten or twenty miles an hour, and you must cut the line to save your lives; he smashes the boat, and perhaps kills some of his assailants; he dies below the surface, and when he dies there he stays below, and you lose him; and sometimes he shows[Pg 66] such an amount of toughness that he seems to bear a charmed life. We fight him with harpoon and lance, and in these later days they have an invention called the bomb-lance or whaling-gun. A bomb-shell is thrown into him with a gun like a large musket, and it explodes down among his vitals. There's another gun that is fastened to the shaft of a harpoon, and goes off when the whale tightens the line; and there's another that throws a lance half-way through him. Well, there are whales that can stand all these things and live.The boys had too much to do in the way of sight-seeing to spend more time over conundrums. They proceeded to explore the interior of the junk, and to look about the decks in the hope of finding something new in the way of navigation. They discovered that there was considerable space for the stowage of cargo, in consequence of the great width of the craft in proportion to her length. The accommodations of the crew were not extensive; but as they did not expect much, they were not likely to complain. As the boys were near the bow of the junk, they came upon two of the sailors at dinner; the meal consisting of rice and fish, which they ate[Pg 274] with the aid of chopsticks. The men were squatted on the deck in front of their food, or rather they had the food in front of themselves, and they evidently were the possessors of good appetites, to judge by the eagerness with which they attended to business and paid no heed to the strangers.
