TWO:Mr Keeling was accustomed to consider the hour or two after lunch on Sunday as the most enjoyable time in the week, for then he gave himself up to the full and uninterrupted pursuit of his hobby. None of his family ever came into his study without invitation, and since he never gave such invitation, he had no fear about being disturbed. Before now he had tried to establish with one or other of them the communication of his joy in his books: he had asked Alice into his sanctuary one Sunday, but when he had shown her an exquisitely tooled binding by Cameron, she had said, Oh, what a pretty cover! A pretty cover!... somehow Alices appreciation was more hopeless than if she had not admired it at all. Then, opening it, she had come across a slightly compromising picture of Bacchus and Ariadne, and had turned over in such a hurry she had crumpled the corner of the page. Her father hardly knew whether her maidenly confusion was not worse than the outrage on his adored volume. Stern moralist and Puritan though he was, this sort of prudery seemed to him an affectation that bordered on imbecility. On another he had asked Hugh to look at his books,{32} and Hugh had been much struck by the type of the capital letters in an edition of Omar Khayyam, wondering if it could be enlarged and used in some advertisement of the approaching summer sale at the stores. Thats the sort of type we want, he said. It hits you in the eye; that does. You cant help reading what is written in it. Very likely that was quite true, for Hugh had an excellent perception in the matter of attractive type and arrangement in the advertising department, but his father had shut up the book with a snap, feeling that it was in the nature of a profanity to let the aroma of business drift into an atmosphere incense-laden with his books. His wife presented an even more hopeless case, for she was apt to tell her friends how fond her husband was of reading, and how many new editions he had ordered for his library. Clearly, if this temple was to retain its sense of consecration he must permit no more of these infidel intruders.

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:Frank wished to know if the women were desirous of having the custom abolished, but on this point it was not easy for him to obtain precise information. The Doctor thought it was a matter of individual rather than of general preference, and that the views of the women were largely influenced by those of their husbands. "The Japanese wives," said he, "are like the wives of most other countries, and generally wish to do according to the tastes and desires of their husbands. As you grow older you will find that the women of all lands endeavor to suit their modes of dressing and adornment to the wishes of the men with whom they come mostly in contact; of course, there are individual exceptions, but they do not weaken the force of the general rule. In America as in England, in China as in Japan, in India as in Peru, it is the fancy of the men that governs the dress and personal decoration of the other half of the race. As long as it was the fashion to blacken the teeth in this country, the women did it without a murmur; but as soon as the men showed a willingness for them to discontinue the practice, and especially when that willingness became a desire, they began to discontinue it. Twenty years from this time, I imagine, the women with blackened teeth will be less numerous than those at present with white ones.
- 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:"Ah, now he is discovered, surely not. I think he will turn back at Wiggins."
The aromatic polyimide membrane is highly permeable to water vapor but less permeable to vapors of organic compounds such as alcohol etc.
THREE:
- 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:
Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
