TWO:Even when Paris was reached, and Beccaria and Alessandro were warmly welcomed by DAlembert, Morellet, Diderot, and Baron Holbach, the homesickness remained. You would not believe, says Beccaria to his wife, the welcomes, the politeness, the demonstrations of friendship and esteem, which they have shown to me and my companion. Diderot, Baron Holbach, and DAlembert especially enchant us. The latter is a superior man, and most simple at the same time. Diderot displays enthusiasm and good humour in all he does. In short, nothing is wanting to me but yourself. All do their best to please me, and those who do so are the greatest men in Europe. All of them deign to listen to me, and no one shows the slightest air of superiority. Yet[24] Morellet tells us that even on arrival Beccaria was so absorbed in melancholy, that it was difficult to get four consecutive words from his mouth.

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 recognition of this regulation of resentment as the main object of punishment affords the best test for measuring its just amount. For that amount will be found to be just which is necessary; that is to say, which just suffices for the object it aims atthe satisfaction of general or private resentment. It must be so much, and no more, as will prevent individuals from preferring to take the law into their own hands[84] and seeking to redress their own injuries. This degree can only be gathered from experience, nor is it any real objection to it, that it must obviously be somewhat arbitrary and variable. Both Wladimir I., the first Christian Czar of Russia, and Wladimir II. tried the experiment of abolishing capital punishment for murder; but the increase of murders by the vendetta compelled them to fall back upon the old modes of punishment.[46] Some centuries later the Empress Elizabeth successfully tried the same experiment, without the revival of the vendetta, the state of society having so far altered that the relations of a murdered man no longer insisted on the death of his murderer. But had Elizabeth abolished all legal punishment for murderhad she, that is, allowed no public vendetta of any kindundoubtedly the vendetta would have become private again.No law ought to be promulgated that has not force to back it, or that the nature of things deprives of validity; and as minds are ruled by opinion, which[224] itself follows the slow and indirect impressions of legislation, whilst it resists those that are direct and violent, the most salutary laws become infected with the contempt felt for useless laws, and are regarded rather as obstacles to be surmounted than as the deposit of the public welfare.
  • 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:CHAPTER XVI. CAPITAL PUNISHMENT.It is impossible to prevent all the disorders that may arise in the universal conflict of human passions. Their increase depends on that of population and on the crossings of private interests, which cannot be directed with geometrical exactness to the public welfare. In political arithmetic the calculation of probabilities must be substituted for mathematical exactness. Glance at the history of the world, and you will see disorders increase with the increase of the bounds of empire; thus national feeling being to the same extent diminished, the general inducement to crime increases with the greater interest of each individual in such disorders, and on this account the necessity for aggravating penalties ever continues to increase.

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

THREE:But commerce and the interchange of the pleasures of luxury have this drawback, that however many persons are engaged in their production, they yet begin and end with a few, the great majority of men only enjoying the smallest share of them, so that the feeling of misery, which depends more on comparison than on reality, is not prevented. But the principal basis of this happiness I speak of is personal security and liberty under the limitations of the law; with these the pleasures of luxury favour population, and without them they become the instrument of tyranny. As the noblest wild beasts and the freest birds remove to solitudes and inaccessible forests, leaving the fertile and smiling plains to the wiles of man, so men fly from pleasures themselves when tyranny acts as their distributor.But of far greater historical interest than such criticism is that of Ramsay, the Scotch poet and painter, to whom a copy of Beccarias treatise had been shown by Diderot, and who wrote a letter about it to the latter, which, though it contains some very just criticisms on Beccaria, yet reads for the most part very curiously by the light of subsequent history, and illustrates graphically the despair of all reform then felt by most men of reflection.[8]
  • 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.
