TWO:"But the streets and houses?" hazarded Allingham, "aren't they like ours?"Ah, that would be a great treat. Let us do that, in any case, Sir Thomas. Surely we can go in some back way so as to escape my wifes notice if she is really waiting outside. It will do her good to wait: she is very impatient.

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:There is very little of what we call privacy in a Japanese house, as the paper screens are no obstructors of sound, and a conversation in an ordinary tone can be heard throughout the entire establishment. It is said that this form of building was adopted at a time when the government was very fearful of conspiracies, and wished to keep everybody under its supervision. Down to quite recent times there was a very complete system of espionage all over the country; and it used to be said that when three persons were together, one of them was certain to be a spy, and the other two were pretty sure to be spies as well. At the time Commodore Perry went to Japan, it was the custom to set a spy over every official to observe what he did and report accordingly. The system has been gradually dropped, but it is said to exist yet in some quarters.
  • 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:Hitherto Mr Keeling had devoted his mind to his own immediate concerns which were those of eating. He had no wish to get worried with Mrs Goodford, but it seemed that mere politeness required an answer to this.

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

THREE:It was the envelope which had contained Coralie Rothvelt's pass. Its four flaps were spread open, and on the inside was scrawled in a large black writing the following:
  • 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:"Oh," said Gregg, and his face became blank. "Anyhow, just tell him that he must run when he's called."
