TWO:The young men gladly went in, and after giving them an excellent djeuner, their host lighted a candle, took a spade, and told them to follow him. He led them into the garden, cleared away some earth with his spade, and uncovered a stone. This he lifted up, disclosing an underground passage through which he led the way. It ended in a cavern in which lay the whole of their family plate and valuables which this excellent man had saved and concealed during all these years.Arnault, in his memoirs, relates that he was brought up at Versailles, where he was at school from 1772 to 1776, and often saw Louis XV. pass in his carriage. The King had a calm, noble face and very thick eyebrows. He took not the slightest notice of the shouts of Vive le roi from the boys drawn up in a line, or from the people; neither did Louis XVI. when he succeeded him.

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:They were kept a fortnight at the Hague by the storms and shipwrecks going on, but early in January they decided to embark for England. The cold was fearful, and, wrapped in fur cloaks, fur boots and caps, they set off to drive seven or eight leagues perched on the top of open baggage waggons, seated upon the boxes, so unsafe that the Baron de Breteuil, who was with them, fell off and put his wrist out.And yet amidst all the horrors and miseries even of the six last and most awful weeks of the Terror, in daily peril of death and amongst the most frightful hardships, laughter and jokes were heard in the prisons, friendships and love affairs were formed; every one was the friend of every one.
  • 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:

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

THREE:Mlle. Georgette Ducrest, a cousin of Mme. de Genlis, had emigrated with her family, who were [454] protected by Mme. de Montesson and Josphine, and now applied for radiation.No, Madame, replied Casanova, he was a painter who amused himself by being ambassador.
  • 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.
