TWO:And if that had been all! But dozens of boys and young men had been taken to Bilsen as prisoners. There had been a real hunt for all able-bodied lads who might be of any use in the Belgian army. Women and old men were compelled by threats to betray the hiding-places of their sons or husbands, and if one of them was found hidden away under straw or in barns, he was ill-treated or beaten with rifle-butts. Some fled to Maastricht, others to the Campine, the northern part of Belgium. I presume that both groups have at length arrived in Antwerp.

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:Trip-hammers employed in forging bear a close analogy to, and were no doubt first suggested by, hand-hammers. Being the oldest of power-forging machines, and extensively employed, it will be proper to notice trip-hammers before steam-hammers.
  • 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:It is not the intention to discuss patent law, nor even to estimate what benefits have in the past, or may in the future, be gained to technical industry by the patent system, but to impress engineering apprentices with a better and more dignified appreciation of their calling than to confound it with chance invention, and thereby destroy that confidence in positive results which has in the past characterised mechanical engineering; also to caution learners against the loss of time and effort too often expended [161] in searching after inventions."Yes, sir."

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

THREE:I had a short chat with the wounded men near the various houses, on demand showed my passport to those in authority, and was advised as a friendly Netherlander to return, as it was extremely dangerous on the road. But I did not dream of doing34 this, as long as I was not compelled, and went on towards Lige amidst this maddening thunder."The Spaniard with the mantilla," Lawrence whispered, "the evil genius of the house. We shall see something more presently. Not that we are going to interfere. On the whole, I rather want these people to get the jewels."
  • 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:Charlton looked up in quick surprise.
