TWO:In the immediate neighbourhood of the railway station a house was being built, of which only the foundations were laid. The place showed nothing beyond a huge cavity. I had noticed already several times that there was an atrocious stench near the station, which at last became unendurable. Pastor Claes, who courageously entered all destroyed houses to look for the dead, had discovered the victims also in this place. In the cave just mentioned he found sixteen corpses of burghers, two priests among them. In order to remove them from the street the Germans had simply thrown them into that cave, without covering the corpses in any way. They had been lying there for days, and were decaying rapidly."Oh, mother," she cried. "What is the matter? What have they been doing to you?"

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:Well be a regular Sky Patrol! exulted Sandy. And watch what goes on while you do the control joband, that waynothing can go wrong! Not with the Sky Patrol over-seeing! Dick, too, spoke overconfidently.
  • 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:Dimension lines should be in blue, but may be in red. Where to put them is a great point in draughting. To know where dimensions are required involves a knowledge of fitting and pattern-making, and cannot well be explained; it must be learned in practice. The lines should be fine and clear, leaving a space in their centre for figures when there is room. The distribution of centre lines and dimensions over a drawing must be carefully studied, for the double purpose of giving it a good appearance and to avoid confusion. Figures should be made like printed numerals; they are much better understood by the workman, look more artistic, and when once learned require but little if any more time than written figures. If the scale employed is feet and inches, dimensions to three feet should be in inches, and above this in feet and inches; this corresponds to shop custom, and is more comprehensive to the workman, however wrong it may be according to other standards.
  • 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 door closed quietly behind Bruce. Just for a moment the lace-clad figure lay motionless on the couch. Then she rose and swept up and down the room like a tornado. She had shown her hand, she had betrayed her secret, and the man who had her heart scorned her. She was filled with shame and rage and hate.It is a strange thought that with all the order, system, and regularity, existing in nature, there is nothing but the movements of the heavenly bodies constant enough to form a base for gauging tests. The French standard based upon the calculated length of the meridian may be traced to this source.
