TWO:On their return from the garden they stopped at a place where eggs are hatched by artificial heat. They are placed over brick ovens or furnaces, where a gentle heat is kept up, and a man is constantly on watch to see that the fire neither burns too rapidly nor too slowly. A great heat would kill the vitality of the egg by baking it, while if the temperature falls below a certain point, the hatching process does not go on. When the little chicks appear, they are placed under the care of an artificial mother, which consists of a bed of soft down and feathers, with a cover three or four inches above it. This cover has strips of down hanging from it, and touching the bed below, and the chickens nestle there quite safe from outside cold. The Chinese have practised this artificial hatching and rearing for thousands of years, and relieved the hens of a great deal of the monotony of life."We stopped at the village of Sha-ho, about twenty miles from Pekin; and as we had started a little late, and it was near sunset, we concluded to spend the night there. There was not much to see at the village, except a[Pg 382] couple of fine old bridges built of stone, and so solid that they will evidently last a long time. A barber came around and wanted to shave us, but for several reasons we declined his proposal, and satisfied ourselves by seeing him operate on a native customer. The Chinese razor is a piece of steel of a three-cornered shape, and is fastened to a handle about four inches long. It is kept very sharp, as any well-regulated razor should be, and a barber will handle it with a great deal of dexterity. The Chinese haven't much beard to shave off, but they make up for it with a very thick growth of hair, which is all removed every ten or twelve days, with the exception of a spot on the crown about four inches in diameter. The hair on this spot is allowed to grow as long as it will, and is then braided into the cue or pigtail that everybody knows about.

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:"Not a great distance from the five-storied pagoda we saw the leper hospital, where the unfortunate people who suffer from leprosy are compelled to live, and soon to die. The sight was a horrible one, and we did not want to stay long among the sufferers. We had expected to find a large[Pg 414] building, like a hospital in America, but instead of this there were several small buildings, grouped together in a little village, some of the houses having garden patches near them. The people were lying or sitting around in the sun, and some few of them were at work in the gardens. The most were not able to do anything, as they were suffering from the disease, which was slowly killing or crippling them.
  • 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:"Perhaps I ought to explain," he continued. "You see, I'm a clockwork man."

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 shall be better, said he. Considering{131} that he saw me through an illness last year, the least I can do is to hold on as long as I can.
  • 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:Where the tireless sea-birds sweep;

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