TWO:"Quick," cried Balmayne, as he pulled his companion to her feet. "You don't seem to be hurt, It's a mystery we were not killed. There's a rail out of the long line of rails in the square yonder, close here. Ah! Now you squeeze through and I'll follow. We shall save our skins yet."

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:Captain Parks came up later with the real stones and while he waited for my wife to finish her costume, he examined the fire escape window and was sure that someone had entered and left by that.We have now to show what new beliefs gained most ground, and what old beliefs were most successfully revived, through the combination of favourable conditions, an analysis of which has been attempted in the preceding pages. Among the host of creeds which at this period competed with one another for the favour of the rich or for the suffrages of the poor, there were some that possessed a marked advantage over their rivals in the struggle for existence. The worship of Nature considered as imaging the vicissitudes of human life, could not fail to be the most popular of any. All who desired a bond of sympathy uniting them with their fellow-subjects over the whole empire, and even with the tribes beyond its frontiers, might meet on this most universal ground. All who wished to combine excitement with devotion were attracted by the dramatic representation of birth and death, of bereavement and sorrow and searching, of purification through suffering, and triumphant reunion with the lost objects of affection in this or in another world. Inquisitive or innovating minds were gratified by admission to secrets a knowledge of which was believed to possess inestimable value. And the most conservative could see in such celebrations an acknowledgment, under other forms, of some divinity which had always been reverenced in their own home, perhaps even the more authentic reproduction of adventures already related to them as dim and uncertain traditions of the past. More than one such cultus, representing under the traits of personal love and loss and recovery, the death of vegetation in winter and its return to life in spring, was introduced from the East, and obtained a wide popularity through the empire. Long before the close of the republic, the worship of Cybele was established in Rome with the sanction of the Senate. Other Asiatic deities of a much less respectable character, Astarte and the so-called Syrian goddess, though not officially215 recognised, enjoyed a celebrity extending to the remotest corners of the western world.327 Still greater and more universal was the veneration bestowed on Isis and Serapis. From the prince to the peasant, from the philosopher to the ignorant girl, all classes united in doing homage to their power. Their mysteries were celebrated in the mountain valleys of the Tyrol, and probably created as much excitement among the people of that neighbourhood as the Ammergau passion-play does at present.328 An inscription has been discovered describing in minute detail an offering made to Isis by a Spanish matron in honour of her little daughter. It was a silver statue richly ornamented with precious stones, resembling, as our authority observes, what would now be presented to the Madonna,329 who indeed is probably no more than a Christian adaptation of the Egyptian goddess. And Plutarch, or another learned and ingenious writer whose work has come down to us under his name, devotes a long treatise to Isis and Osiris, in which the mythical history of the goddess is as thickly covered with allegorical interpretations as the statue dedicated to her by the Spanish lady was with emeralds and pearls.
  • 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:Prout snapped his note-book together and put it in his pocket."Which isn't worth the trouble when you've got it."

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

THREE:In order to render what is said of shop processes more easily understood, it will be necessary to change the order in which they have been named. Designing, and many matters connected with the operation of machines, will be more easily learned and understood after having gone through with what may be called the constructive operations, such as involve manual skill.
  • 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 applause was gradually dying down. Hetty, conscious of a figure behind her, moved back. The box door shut and the air grew oppressive. Leona Lalage, still talking earnestly to her companion, motioned Hetty to open it.We have now reached a point where Greek philosophy seems to have swung back into the position which it occupied three hundred years before, towards the close of the Peloponnesian War. The ground is again divided between naturalists and humanists, the one school offering an encyclopaedic training in physical science and exact philology, the other literary, sceptical, and limiting its attention to the more immediate interests of life; but both agreeing in the supreme importance of conduct, and differing chiefly as to whether its basis should or should not be sought in a knowledge of the external world. Materialism is again in the ascendant, to this extent at least, that no other theory is contemplated by the students of physical science; while the promise of a spiritualistic creed is to be found, if at all, in the school whose scepticism throws it back on the subjective sphere, the invisible and impalpable world of mind. The attitude of philosophy towards religion has, indeed, undergone a marked change; for the Stoic naturalists count themselves among the159 most strenuous supporters of beliefs and practices which their Sophistic predecessors had contemned, while the humanist criticism is cautiously guarded by at least an external conformity to established usage; but the Platonic doctrine of immortality has disappeared with the dogmatic spiritualism on which it rested; and faith in superior beings tends to dissociate itself from morality, or to become identified with a simple belief in the fixity of natural law.
