TWO:It was so good of you to let me come and see your books, Mr Keeling, she said. My brother has often told me what delightful Sunday afternoons he has passed with you here."Never had the chance to write it," Lawrence cried. "But I worked it all out. Wicked woman, revenge, plot to bring hero within the grip of the law. It's pigeonholed in my writing desk, and labelled 'The Corner House.' But I don't suppose it will ever be written."

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:"Perhaps I ought to explain," he continued. "You see, I'm a clockwork man."The Doctor thought he had given the boys quite as much information as they would be likely to remember in his dissertation, and suggested that they should endeavor to recapitulate what he had said. Frank thought the discussion had taken a wide range, as it had included the status of the four classes of Japanese society, had embraced the Samurai and their peculiarities, some of the changes that were wrought by the revolution,[Pg 226] and had told them how executions were conducted in former times. Then they had learned something about hari-kari and what it was for; and they had learned, at the same time, the difference between the old courts of justice and the new ones. What with these things and the naval progress of the empire of the Mikado, he thought they had quite enough to go around, and would be lucky if they remembered the whole of it.
  • 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:"We hang them to the first tree."

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

THREE:
  • 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 boys were not inclined to stay long in the cave, as the sound of the waters beating in at the entrance was almost deafening. They very soon sought the open air, where a new entertainment awaited them. There was a group of men and boys on the rocks at the entrance of the[Pg 180] cavern, and they called to the strangers to throw coins into the water and see how soon they could be recovered by diving. Frank threw a small piece of silver into the clear water of the Pacific, and in an instant half a dozen boys sprang for it. One of them caught it before it reached the bottom, and came up with the piece in his mouth. Several coins were thrown, with a similar result; and finally it was proposed to let the money reach the bottom before the divers started. This was done, and, as the depth was about twelve feet, the work of finding the bit of silver was not very easy. But it was found and brought to the surface; and after the divers had been complimented on their skill, our friends moved on. It is hardly necessary to add that the money thrown into the water became the property of the youth who secured it; though it was rumored that the divers were associated, and everything obtained went into a common purse. The Oriental people are famous for their guilds, or labor and trade associations, and nearly every occupation in life is under the control of a guild, which has very arbitrary rules. It is not at all impossible that the boys who dive for small coins at Enoshima are under the control of an association, and that its rules and regulations may have been in force for hundreds of years.The General looked at me between puffs of his cigar. "I hear you've ridden over fifty miles to-day."
