TWO:Frederick on the 17th, the day after the departure of the Austrian army, invested Neisse. He had an embarrassing part to play. He was to conduct a sham siege in the presence of M. Valori, who was not only a man of ability, but who possessed much military intelligence. Feigning the utmost zeal, Frederick opened his trenches, and ostentatiously man?uvred his troops. He sent the young Prince Leopold, with fifteen thousand horse and foot, into the Glatz country, many leagues to the east, to guard against surprise from an enemy, where no enemy was to be found. He marked out his parallels, sent imperious summonses for surrender, and dispatched reconnoitring parties abroad. M. Valori began to be surprisedamazed. What does all this mean? he said to himself. They have great need of some good engineers here.The king was so impressed by this firm attitude of his physician that he even made an apology for his rudeness. As Frederick William was now convinced that ere long he must appear before the tribunal of God, he gradually became a little more calm and resigned.29 It is, however, evident that the Crown Prince still had his share of earthly annoyances, and certainly his full share of earthly frailties. In a letter to his friend Suhm, written this summer, he says:

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:Ruppin, where the Crown Prince continued to reside for several years, was a small, dull town of about two thousand inhabitants. The only life it exhibited was found in the music and drillings of the garrison. The only important event in its history was the removal of the Crown Prince there. Of what is called society there was none. The hamlet was situated in the midst of a flat, marshy country, most of it quite uncultivated. The region abounded in peat bogs, and dark, still lakes, well stocked with fish.
  • 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:Voltaire hated M. Maupertuis. He was the president of the Berlin Academy, and was regarded by Voltaire as a formidable rival. This hatred gave rise to a quarrel between Frederick and Voltaire, which was so virulent that Europe was filled with the noise of their bickerings. M. Maupertuis had published a pamphlet, in which he assumed to have made some important discovery upon the law of action. M. K?nig, a member of the Academy, reviewed the pamphlet, asserting not only that the proclaimed law was false, but that it had been promulgated half a century before. In support of his position he quoted from a letter of Leibnitz. The original of the letter could not be produced. M. K?nig was accused of having forged the extract. M. Maupertuis, a very jealous, irritable man, by his powerful influence as president, caused M. K?nig to be expelled from the Academy.Poniatowski was elected King of Poland on the 7th of September, 1764, and crowned on the 25th of November. He was then thirty-two years of age, and the scarcely disguised agent of Catharine. Two or three years passed of wars and rebellions, and all the usual tumult of this tumultuous world. In August, 1765, the Emperor Francis died. He was at Innsprück, attending the marriage festivities of his second son Leopold. About nine oclock in the evening of the 18th, while sauntering through the rooms in the midst of the brilliant gala, he was struck with apoplexy. He staggered for a moment, fell into the hands of his son Joseph, and instantly died.

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

THREE:Maximilian Joseph, son of the emperor, was at the time of his fathers death but seventeen years of age. He was titular Elector of Bavaria; but Austrian armies had overrun the electorate, and he was a fugitive from his dominions. At the entreaty of his mother, he entered into a treaty of alliance with the Queen of Hungary. She agreed to restore to him his realms, and to recognize his mother as empress dowager. He, on the other hand, agreed to support the Pragmatic Sanction, and to give his vote for the Grand-duke Francis as Emperor of Germany.
  • 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:All Europe, England alone excepted, was aroused against him. Armies were every where being marshaled. The press of all continental Europe was filled with denunciations of his crimes and encroachments. Not all his efforts to assume a careless air411 could efface from his countenance the impression left there by the struggles of his soul. His features, as seen in a portrait painted about this time, are expressive of the character of an anxious and unhappy man.
