TWO:The seaplane wavered, caught itself in a steadier line. In the pursuing airplane three youthful faces grew intent.

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:This mode of reasoning will lead to proper estimates of the difference in value between good tools and inferior tools; the results of performance instead of the investment being first considered, because the expenses of operating are, as before assumed, usually ten times as great as the interest on the value of a machine.
  • 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.

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

THREE:Mr. Everdail proceeded at once to tie himself in his first knot.Leona smiled with contempt as she surveyed the slim figure before her. She was always proud of her strength. She bared her beautiful white arm and showed the strong sinews and muscles under the skin.
  • 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:The religious tendency of Senecas philosophy appears rather in his psychology than in his metaphysics, in the stress which he lays on human immortality rather than in his discussions on creation and divine providence. His statements on this subject are not, indeed, very consistent, death being sometimes spoken of as the end of consciousness, and at other times, as the beginning of a new life, the birthday of eternity, to quote a phrase afterwards adopted by Christian preachers. Nor can we be absolutely certain that the promised eternity is not merely another way of expressing the souls absorption into and identification with the fiery element whence it was originally derived. This, however, is an ambiguity to be met with in other doctrines of a spiritual existence after death, nor is it entirely absent from the language even of Christian theologians. What deserves attention is that, whether the future life spoken of by Seneca be taken in a literal or in a figurative sense, it is equally intended to lead our thoughts away from the world of sensible experience to a more ideal order of things; and, to that extent, it falls in with the more general religious movement of the age. Whether Zeller is, for that reason, justified in speaking of him as a Platonising Stoic seems more questionable; for the Stoics always agreed with Plato in holding that the soul is distinct from and superior to the body, and that it is consubstantial with the animating principle of Nature. The same circumstances which were elsewhere leading to a revival of Platonism, equally tended to develope this side of Stoicism, but it seems needless to seek for a closer connexion between the two phenomena.376There was something about the corner house mystery that gripped the public imagination. There was about it both the realism and the romance that always go to make up a popular sensation.
