TWO:It became now all the more necessary to smash Realf. He could no longer be content with keeping just ahead of him; he must establish a sort of two-power standard, and crush his rival to the earth. That was not a good summer for expansion��a drought baked up the greater part of Sussex, and there was an insect plague in the hops��nevertheless, Reuben bought thirty-five acres of Boarzell, on the east slope, by the road. He was tormented by a fear that Realf would buy the land if he[Pg 235] did not, and, moreover, during May two boards had appeared advertising it as "an eligible building site"; which was possibly bluff, possibly unusual cunning on the part of Flightshot, made resourceful by its straits.When he saw them running along the lane from school, or tramping the fields together��they were always together��or helping with the hops or the hay, his heart would stir with a warm, unwonted sense of fatherhood, not just the proud paternal impulse which had visited him when he held his new-born babies in his arms, but something belonging more to the future than the present, to the days when they should carry on Odiam after his death. For the first time he had sons whom he looked upon not merely as labourers to help him in his work, but as men created in his own image to inherit that work and reap its fruits when he was gone.

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:The sunset guttered like spent candles in the wind��the rest of the sky was grey, like the fields under it. The distant bleating of sheep came through the dropping swale, as Reuben climbed the Moor. His men were still at work on the new ground, and he made a solemn tour of inspection. They were cutting down the firs and had entirely cleared away the gorse, piling it into a huge bonfire. All that remained of Boarzell's golden crown was a pillar of smoke, punctured by spurts and sparks of flame, rising up against the clouds. The wind carried the smell away to Socknersh and Burntbarns, and the farm-men there looked up from their work to watch the glare of Boarzell's funeral pyre.

• 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:"And that the lords shall give up their castles, and keep no retainers, and that all the lawyers shall be hanged!" said Turner.

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).
