TWO:In considering pneumatic machinery there are the following points to which attention is directed:

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:166 "The inquiry also brought to light that the German soldiers on the right bank, who were exposed to the fire of the French, hid themselves here and there behind civilians, women and children.From Vis I went again across the Meuse to the road along the canal. Nearing Haccourt, I noticed that Fort Pontisse was actually silent, but Lierce still in full action. The Germans had mounted long-range guns on the hills between Lancey and Haccourt, whence they could place Fort Lierce under fire. A German officer, after some coaxing, allowed me to witness the operations for a short time. I found a place near some heavy guns, and sat down amid some underwood. The shooting from Lierce was very fierce, but only by the plumes of smoke could I tell whereabouts the fort might be. The shells came down near us, but during the half hour of my stop not one made a hit. They all fell short of us.
  • 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:"And the mending will be a matter of time?"

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

THREE:He was profoundly impressed by the graciousness of his visitor. He even dusted an office chair for her with a clean handkerchief. He seemed a simple sort of man. Leona Lalage had not a high opinion of the police.
  • 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:The entire neighbourhood was still being bombarded from the forts to the north of Lige; several German divisions succeeded, however, in crossing the Meuse near Lixhe. In spite of the shell-fire they passed the pontoon-bridge there, turned into a by-way leading to the canal, near Haccourt, crossed one of the canal-bridges, of which not one had been destroyed, and along another by-way, came to the main road from Maastricht to Tongres, at a spot about three miles from the last-named town.
