TWO:The Japanese dogs were also objects of interest to our young friends, though less so than the cats and the goldfish. They have several varieties of dogs in Japan, some of them being quite without hair, while others have very thick coats. The latter are the most highly prized, and the shorter their noses, the more valuable they are considered. Fred found a dog, about the size of a King Charles spaniel, that had a nose only half an inch long. He was boasting of his discovery, when Frank pointed out one that had less than a third of an inch. Then the two kept on the hunt for the latest improvement in dogs, as Frank expressed it, and they finally found one that had no nose at all. The nostrils were set directly in the end of the little fellow's head, and his under-jaw was so short that the operations of barking and eating were not very easy to perform. In spite of the difficulty of barking, he made a great deal of noise when the boys attempted to examine him, and he gave Frank to understand in the most[Pg 155] practical way that a noseless dog can bite. As they walked away from the shop where they found him, he kept up a continual snarling, which led to the remark by Fred that a noseless dog was very far from noiseless.There is one other thing, he said. You get four days holiday at Christmas, you and your brother. Are you going to spend them here?

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:Tom paused for a moment and began to tremble. His teeth chattered violently, and he looked appealingly at his listeners as though afraid to continue.
  • 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:"I meant it to," said Lilian, firmly. "I want you to be cut to the quick. It's our only chance.""You know how a tea-chest looks, so I need not describe it any more than to say that the chest is lined with tin, and that the tin is carefully soldered, so that not a single particle of dampness can get in while the tea is on the ocean. If it should, the tea would be spoiled, as the least dampness will injure it, and a great deal will make it quite useless. They always try to hurry the new crop of tea as rapidly as they can, since it is the best, and has more and better flavor than the crop of the previous year. When a ship sails with new tea, she races for home as hard as she can go, and the quickest voyages ever made from this part of the world to Europe and America have been made by ships with cargoes of new tea."

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

  • 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:Trust you for hitting the nail on the head, Emmeline, he said. That was why.
