TWO:The kings brother Henry was in command in Saxony, at the head of thirty thousand troops. Frederick wrote to him the characteristic and very judicious advice, Do as energetically as possible whatever seems wisest to you. But hold no councils of war.Daun has thrown up his cards, so the game is not yet lost. Let us repose ourselves for some days, and then go to the assistance of Neisse.123

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:It is perhaps not strange that Frederick should have imbibed a strong feeling of antipathy to Christianity. In his fathers life he had witnessed only its most repulsive caricature. While making the loudest protestations of piety, Frederick William, in his daily conduct, had manifested mainly only every thing that is hateful and of bad report. Still, it is quite evident that Frederick was not blind to the distinction between the principles of Christianity as taught by Jesus and developed in his life, and the conduct of those who, professing his name, trampled those principles beneath their feet. In one of his letters to Voltaire, dated Cirey, August 26, 1736, Frederick wrote:But it was much easier for Frederick to issue these orders than for Leopold to execute them. As Leopold could not, in a day, gather sufficient force to warrant an attack upon the Austrians, the king was greatly irritated, and allowed himself to write to Leopold in a strain of which he must afterward have been much ashamed. On the 19th he addressed a note to the veteran officer couched in the following terms:
  • 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.

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

THREE:BATTLE OF
  • 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:To whose continual sluggishness and strange want of concertto whose incoherency of movements, languor of execution, and other enormous faults, we have owed, with some excuse for our own faults, our escape from destruction hitherto.
