TWO:"About half-past-four. It must have been about that time, because just after I got back to my room the clock struck five. A motor car came up, one of the quietest I have ever heard. As the woman got in she stumbled, and the man swore at her. Then there was the strangest thing, the dull side of the motor car gleamed in places like silver, as if something had been rubbed off it by the woman as she fell. What do I think it was? Well, so far as I could make out, the car was all hung with black crape."Primarily, power is a product of heat; and wherever force and motion exist, they can be traced to heat as the generating element: whether the medium through which the power is [30] obtained be by the expansion of water or gases, the gravity of water, or the force of wind, heat will always be found as the prime source. So also will the phenomenon of expansion be found a constant principle of developing power, as will again be pointed out. As steam-engines constitute a large share of the machinery commonly met with, and as a class of machinery naturally engrosses attention in proportion, the study of mechanics generally begins with steam-engines, or steam machinery, as it may be called.

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:The Roman reformers were satisfied to call themselves Stoics; and, in reviewing the Stoic system, we saw to what an extent they welcomed and developed some of its fundamental180 thoughts. But we have now to add that the current which bore them on had its source deeper down than the elaborate combinations of Zeno and Chrysippus, and entered into the composition of every other system that acted on the Roman intellect simultaneously with theirs. Thus whatever forces co-operated with Stoicism had the effect not of complicating but of simplifying its tendencies, by bringing into exclusive prominence the original impulse whence they sprang, which was the idea of Natural Law. Hence the form ultimately assumed by Roman thought was a philosophy of Nature, sometimes appearing more under a Stoic, and sometimes more under a Cynic guise. Everything in Roman poetry that is not copied from Greek models or inspired by Italian passionin other words, its didactic, descriptive, and satiric elementsmay be traced to this philosophy. Doubtless the inculcation of useful arts, the delight in beautiful scenery, the praises of rustic simplicity, the fierce protests against vice under all its forms, and the celebration of an imperial destiny, which form the staple of Romes national literature, spring from her own deepest life; but the quickening power of Greek thought was needed to develope them into articulate expression.
  • 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:Quickly he lowered the rope till the bulge of it showed that the bottom was reached. He wound up the rope again, and as he did so a grunt of satisfaction escaped him. It was far better than he had expected.Aye, if Joves virgin daughter Justice shared

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

THREE:"That way, sir!"
  • 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:Lawrence laid a hand on his friend's shoulder.He was an efficient officer in his way, only, like most members of the force, he lacked imagination. Give him something to work on, and there was not a more efficient detective in New Scotland Yard. But there was no clue here, so he had to fall back on the old familiar methods.

Acetone, ethanol, methyl ethyl ketone, butanol, isopropyl alcohol, ethyl acetate, methyl isobutyl ketone, others (including hexane and toluene).
