TWO:A kshatriya, a very old man, had seen me yesterday returning from Ramnagar with my necklet of silver threads. Convinced by this that I must be "a Europe Rajah," he tormented me to grant him a title. He wanted to be Raj Bahadur; this was the height of his ambition. After following me about the bazaar all the morning, he sat for a long time in my room. So, to get rid of him, seeing[Pg 180] that he persisted in hoping that I should call him Raj Bahadur, I did so; this, however, did not satisfy him: I must write it down on paper. At last I consented. Quite delighted now, he went off to shout the words to his friends, who had been waiting for him in the garden, and then, very solemn, and conscious of his new dignity, he disappeared down the road.

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:In the heart of Agra towards evening people were busy in the square of the Jumna Musjid stretching pieces of stuff over rather low poles to form a tent. Then in long file came the labourers from a famine-camp, with their sleep-walking gait, their glassy eyes, their teeth showing like those of a grinning skull. Rags in a thousand holes scarcely covered the horrors of their fleshless bodies.
  • 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:Pilgrims crowd the courts and the temples. All, when they speak, hold a hand or a corner of their[Pg 76] robe before their lips to avoid swallowing the tiniest insect, which would avert the favour of the gods. They bring offerings of rice or gram in little bags of faded silk, pale pink, or green, and gold thread; the poorest have bags of red and white beads.

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

THREE:At the last moment some porters, preceded by two sowars in uniform and holding pikes, bore a large palankin, hermetically closed, to the door of a first-class carriage, and softly set it down. The carriage was opened for a moment: I could see within a party of women-servants, shrouded in white muslin, who were preparing a couch. An old negress handed out to the porters a large sheet, which they held over the palankin, supporting it in such a way as to make a covered passage screening the carriage door. There was a little bustle under the sheetthe end was drawn in, and the sheet fell over the closed door.These gentlemen of the Civil Service would put in an appearance "now and then"the eternal "now and then" that answers every question in India. They stepped out of a buggy, walked quickly round, had seen, and were gone again in a great hurry to finish some important work for the next European mail.
  • 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.
