TWO: As soon as the proofs of a crime and its reality are fully certified, the criminal must be allowed time and opportunity for his defence; but the time allowed must be so short as not to interfere with the speediness of his punishment, which, as we have seen, is one of the principal restraints from crime. A false philanthropy seems opposed to this shortness of time; but all doubt will vanish, on reflection that the more defective any system of law is, the greater are the dangers to which innocence is exposed.

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:
  • 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 XXX. THEFTS.

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: Wise governments suffer not political idleness in the midst of work and industry. I mean by political idleness that existence which contributes nothing to society either by its work or by its wealth; which gains without ever losing; which, stupidly admired and reverenced by the vulgar, is regarded by the wise man with disdain, and with pity for the beings who are its victims; which, being destitute of that stimulus of an active life, the necessity of preserving or increasing[222] the store of worldly goods, leaves to the passions of opinion, not the least strong ones, all their energy. This kind of idleness has been confused by austere declaimers with that of riches, gathered by industry; but it is not for the severe and narrow virtue of some censors, but for the laws, to define what is punishable idleness. He is not guilty of political idleness, who enjoys the fruits of the virtues or vices of his ancestors and sells in exchange for his pleasures bread and existence to the industrious poor, who carry on peacefully the silent war of industry against wealth, instead of by force a war uncertain and sanguinary. The latter kind of idleness is necessary and useful, in proportion as society becomes wider and its government more strict.
