TWO:He moved straight landward through the cottonwoods, followed by the men in single file, but halted them while the rear was still discernible in the green tangle. Presently they unslung carbines, and I distinctly heard galloping. It was not far beyond the cottonwoods. The Yankees were after us. Suddenly it ceased. Over yonder, shoreward in the thicket, came a sharp command and then a second, and then, right on the front of the jungle, at the water's edge, the shots began to puff and crack, and the yellow river out here around the boat to spit!--spit!--in wicked white splashes. Every second their number grew. Behind me Quinn and his men stole away. But orders are orders and I had no choice but to watch the boat. The man in the stern had his back to me, and no face among the other five did I know. They were fast getting away, but the splashes came thick and close and presently one ball found its mark. The man at the stern hurriedly changed places with an oarsman; and as the relieved rower took his new seat he turned slowly upon his face as if in mortal pain, and I saw that the fresh hand at the oar was the brother of Major Harper. Just as I made the discovery "Boom!" said my small dust-cloud across the river, and "hurry-hurry-hurry-hurry-hurry-hurry-hurry--" like a train on a trestle-work--"boom!"--a shell left its gray track in the still air over the skiff and burst in the tops of the cottonwoods. The green thicket grew pale with the bomb's white smoke, yet "crack! crack!" and "spit! spit!" persisted the blue-coats' rifles. "Boom!" said again the field-piece on yonder side the water. Its shell came rattling through the air to burst on this side, out of the flashing and cracking of rifles and the sulphurous bomb smoke arose cries of men getting mangled, and I whimpered and gnawed my lips for joy, and I watched the boat, but no second shot came aboard, and--"Boom!--hurry-hurry-hurry- hurry"--ah! the frightful skill of it! A third shell tore the cottonwoods, its smoke slowly broadened out, a Federal bugle beyond the thicket sounded the Rally, and the cracking of carbines ceased.The evidences of a large population along the Yang-tse were easy to see; but, nevertheless, Frank and Fred were somewhat disappointed. They had read of the overcrowded condition of China, and they saw the great numbers of boats that navigated the river, and consequently they looked for a proportionately dense mass of people on shore. Sometimes, for two or three hours at a time, not a house could be seen; and at others the villages were strung along in a straggling sort of way, as though they were thinly inhabited, and wished to make as good a show as possible. There were many places where the land did not seem to be under cultivation at all, as it was covered with a dense growth of reeds and rushes. In some localities the country appeared so much like a wilderness that the boys half expected to see wild beasts running about undisturbed; they began to speculate as to the kind of beasts that were to be found there, and finally questioned Dr. Bronson on the subject.

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:She gave him a cheerful kiss, she tapped the{311} barometer, and, taking Alice in tow, she left him. Their cheerful voices, talking about the slippers, died away as they went upstairs.
  • 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:She had her hands full of the sheets, and he walked with her as far as the door of the very small room where the typewriting was to be done, and opened it for her. It was built out under the tiles, and was excessively hot and stuffy on this warm September morning.

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

THREE:"The way of it was this. The lookout in the cross-treeswe always keep a man up aloft to look out for whales when we're on cruising groundthe man had called out, 'There she blows!' and everybody was on his feet in an instant.Lord Inverbroom suddenly stiffened.
  • 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.

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