TWO:But Frederick did not seem to think himself at all bound by his treaty obligations with France to refrain from entering into secret arrangements with the foe which would promote his interests, however antagonistic those arrangements might be to his assumed obligations. He was the ally of France in the attempt to wrest territory from the young Queen of Austria, and to weaken her power. His armies and those of France were acting in co-operation. Frederick now proposed to the common enemy that, if Silesia were surrendered to him, he would no longer act in co-operation with his ally; but, that France might not discover his perfidy, he would still pretend to make war. The Austrians were to amuse themselves in defending Neisse from a sham siege until the pleasant weeks of autumn were gone, and then they were to march, with all their guns and ammunition, south to Vienna, there to fight the French. Frederick, still assuming that he was the ally of France, was to avail himself of the excuse that the season of ice and snow was at hand, and withdraw into winter quarters. Such, in general, were the terms which Frederick authorized his minister, Goltz, to propose to Lord Hyndford, as the agent of England and Austria.About two hundred miles south of Berlin there was quite an important marquisate called Baireuth. The marquis had a good-looking young son, the heir-apparent, who had just returned from the grand tour of Europe. Upon the death of his father he would enter upon quite a rich inheritance. This young marquis, Frederick by name, Baron Borck proposed as a substitute for77 the Duke of Weissenfels. It was understood that Wilhelmina was such a prize that kings, even, would be eager to obtain her hand. There could therefore be no doubt but that the Marquis of Baireuth would feel signally honored by such nuptials. The worn and weary mother eagerly accepted this proposal. She suggested it to the king. Sullenly he gave it his assent, saying, I will passively submit to it, but will take no active part whatever in the affair. Neither will I give Wilhelmina one single copper for dowry.

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:Yesterday I wrote to you to come; to-day I forbid it. Daun is marching upon Berlin. Fly these unhappy countries. This news obliges me again to attack the Russians between here and Frankfort. You may imagine if this is a desperate resolution. It is the sole hope that remains to me of not being cut off from Berlin on the one side or the other. I will give these discouraged troops brandy, but I promise myself nothing of success. My one consolation is that I shall die sword in hand.
  • 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 have settled our winter quarters. I have yet a little round to take, and afterward I shall seek for tranquillity at Leipsic, if it be to be found there. But, indeed, for me tranquillity is only a metaphysical word which has no reality.

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:

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