TWO:When you find it very necessary, yet very difficult, to gain any intelligence of the enemy, there is another expedient, though a cruel one. You take a rich burgher, possessed of rich lands, a wife, and children. You oblige him to go to the enemys camp, as if to complain of hard treatment, and to take along with him, as his servant, a spy who speaks the language of the country; assuring him at the same time that, in case he does not bring the spy back with him, after having remained a sufficient time in the enemys camp, you will set fire to his house, and massacre his wife and children. I was forced to have recourse to this cruel expedient. It answered my purpose.173

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:At parting, the king bore magnanimous testimony to the fidelity of his spiritual advisers. He said to M. Roloff, who had been the principal speaker, You do not spare me. It is right. You do your duty like an honest Christian man.

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

THREE:When you sent me, inclosed in your letter, those verses for our Marcus Aurelius of the North, I fully intended to pay my court to him with them. He was at that time to have come to Brussels incognito. But the quartan fever, which unhappily he still has, deranged all his projects. He has sent me a courier to Brussels, and so I set out to find him in the neighborhood of Cleves.The king, as we have mentioned, allotted to his son a very moderate income, barely enough for the necessary expenses of his establishment. But the prince borrowed money in large sums from the Empress of Germany, from Russia, from England. It was well known that, should his life be preserved, he would soon have ample means to repay the loan. Frederick William probably found it expedient to close his eyes against these transactions. But he did not attempt to conceal the chagrin with which he regarded the literary and voluptuous tastes of his son.
  • 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:

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
