TWO:"Soon-keong has four gates, and they were opened at a certain hour in the morning. Ward went there secretly one night, and sent fourteen of his men to each of three of the gates, while he himself went with the remaining eight men to the fourth gate. The rebels suspected nothing, and at the usual time the gates were opened. Ward's men rushed in simultaneously at the four gates, made a great noise, set fire to several buildings, killed everybody they met, and pushed on for the centre of the town. In less than ten minutes the enemy had fled, and the battle was over. Ward was in full possession of the place, and a force of the imperial army, which was waiting near by, was marched in, to make sure that the rebels would not return.

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:"The baking serves to fix the colors firmly in their cells, as the fire is hot enough to melt the glass slightly and fuse it to a perfect union with the body of the bowl. For common work, a single coating of enamel and a single baking are sufficient, but for the finer grades this will not answer. Another coating of colors is laid on, and perhaps a third or a fourth, and after each application the bowl is baked again. When this process is finished, the surface is rough, and the bowl is not anything like what we see it now. It must be polished smooth, and, with this object, it is ground and rubbed, first with coarse stones, then with finer ones, then with emery, and finally with powdered charcoal. In this way the bowl was brought to the condition in which you will find it, if it comes all right and uninjured from the box. A good many pieces of this ware are broken in the handling, and consequently they add to the price of those that come out unharmed.
  • 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:II

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

THREE:Oh, I have too many engagements to think of that, she said, and you would not be able to come with me!
  • 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:I have brought the block of your book-plate, sir, she said, with a couple of impressions of it.

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
