TWO:Suddenly several shots sounded in the neighbourhood. The three took their rifles and looked round, somewhat scared. They assured me that they would protect me. If there had been occasion for it, it would have been against their own comrades,117 for a troop of soldiers came sailing along, swinging about their rifles and shooting at the burning houses as they walked on, without rhyme or reason, anyhow and anywhere. These were drunk also. At last I was able to shake off my "friends," and got through another street into the market-place, at the town-hall and St. Peter's Church. The beautiful town-hall happily was not destroyed, as the first reports intimated, but St. Peter's had been damaged most cruelly. The spire had disappeared, the roof collapsed, windows broken, the altar burned, the pulpit badly damaged, and so forth. The two last-named parts were fine works of art.

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:Many days before the Germans marched upon Antwerp I announced the siege in my paper. In Louvain I had seen all the preparations and also the arrival of the Austrian 30?5 c.m. which were intended to batter to ruins the bulwark of the national defence.
  • 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:After the revolution which destroyed the political power of the old aristocracy, there came a further revolution the effect of which was to diminish largely its social predominance. We learn from the bitter sarcasms of Horace and Juvenal that under the empire wealth took the place of birth, if not, as those satirists pretend, of merit, as a passport to distinction and respect. Merely to possess a certain amount of money procured admission to the equestrian and senatorial orders; while a smaller pecuniary qualification entitled any Roman citizen to rank among the Honestiores as opposed to the Humiliores, the latter only being liable, if found guilty of certain offences, to the more atrocious forms of capital punishment, such as death by the wild beasts or by fire.314 Even a reputation for learning was supposed to be a marketable commodity; and when supreme power was held by a philoso207pher, the vulgar rich could still hope to attract his favourable notice by filling their houses with books.315 We also know from Juvenal, what indeed the analogy of modern times would readily suggest, that large fortunes were often rapidly made, and made by the cultivation of very sordid arts. Thus members of the most ignorant and superstitious classes were constantly rising to positions where they could set the tone of public opinion, or at least help to determine its direction.

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

THREE:Nor was this all. Laws and justice once established would65 require to have their origin accounted for, and, according to the usual genealogical method of the early Greeks, would be described as children of the gods, who would thus be interested in their welfare, and would avenge their violationa stage of reflection already reached in the Works and Days of Hesiod.The reader may notice how everything pertaining to patterns and moulding resolves itself into a matter of judgment on the part of workmen, and how difficult it would be to apply general rules.
  • 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:After I had collected some information in the town and my colleague of Het Leven had taken several snapshots, we thought that it was time to look for lodgings and to get our motor-car repaired.After this game had been going on for some time, the order was given: "Everybody must come outside." Doors and windows were forced open and broken, and men, women, and children driven out of the houses. They were at once ruthlessly separated. Men who assisted their aged mothers, or carried their little babies, were taken away from their families, and driven away, leaving their wailing and weeping wives and children behind, while the flames from burning houses threw a lurid light on the sad scenes of that terrible evening.
