TWO:Of course many of the locusts fell on the deck of the steamer, and found their way to the cabins. The flight of the cloud was from south to north, and Frank observed a remarkable peculiarity about the movements of individual members of the immense swarm. He captured several and placed them on the cabin table. No matter in what direction he turned their heads, they immediately faced about towards the north, and as long as they were in the cabin they continued to try to escape on the northern side. After the boat had passed through the swarm, the boys released several of the captives, and found that, no matter how they were directed at the moment of their release, they immediately turned and flew away to the north.

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:
  • 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:FIRST DAY IN JAPAN.

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

THREE:As they approached the station, Frank appeared a little nervous about something. The cause of his anxiety was apparent when the carriage stopped. He was the first to get out and the first to mount the platform. Somebody was evidently waiting for him.
  • 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:Now the Curate, apart from a tendency to lose his head on occasion, was a perfectly[Pg 101] normal individual. There was nothing myopic about him. The human mind is so constituted that it can only receive certain impressions of abnormal phenomena slowly and through the proper channels. All sorts of fantastic ideas, intuitions, apprehensions and vague suspicions had been dancing upon the floor of the Curate's brain as he noticed certain peculiarities about his companion. But he would probably not have given them another thought if it had not been for what now happened.Well, Im sure its little reward one gets for being a mother in these days, she said, or a wife either, for what with your fathers typewriter lording it in the library, and you telling me whats right and what isnt in my own room, theres little left for me to be mistress of. I wear myself to the bone in doing my duty to you and him, and all I get is to be sworn at and scolded, and when I lie awake at night making plans for your future,{227} you tell me that I might just as well have gone to sleep, for you wont permit them. Pray may I go and dress, or haw you any other orders for me?
