TWO: 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. The more speedily and the more nearly in connection with the crime committed punishment shall follow, the more just and useful it will be. I say more just, because a criminal is thereby spared those useless and fierce torments of suspense which are all the greater in a person of vigorous imagination and fully conscious of his own weakness; more just also, because the privation of liberty, in itself a punishment, can only precede the sentence by the shortest possible interval compatible with the requirements of necessity. Imprisonment, therefore, is simply the safe custody of a citizen pending the verdict of his guilt; and this custody, being essentially disagreeable, ought to be as brief and easy as possible. The shortness of the time should be measured both by the necessary length of the preparations for the trial and by the seniority of claim to a judgment. The strictness of confinement should be no more than is necessary either for the prevention of escape or for guarding against the concealment of the proof of crimes. The trial itself should be finished in the shortest time possible. What contrast[186] more cruel than that between a judges ease and a defendants anguish? between the comforts and pleasures of an unfeeling magistrate on the one hand, and the tears and wretchedness of a prisoner on the other? In general, the weight of a punishment and the consequence of a crime should be as efficacious as possible for the restraint of other men and as little hard as possible for the individual who is punished; for one cannot call that a proper form of society, where it is not an infallible principle, that its members intended, in constituting it, to subject themselves to as few evils as possible.

After taking into consideration of the physical and chemical property of solutions, the desired design conditions, and available utilities, we select the most suitable type of system by utilizing our years of experience and excellent results.
In addition, we can offer designs and manufacturing services that take into careful consideration compactness, energy-efficiency, and automatization.

THREE:It was at one time said that the work really was Pietro Verris and not Beccarias, for it was published anonymously, and away from Milan. The domestic circumstances of Pietro lent some countenance to this story, as did also the fact that he charged himself with the trouble of making a correct copy of the manuscript, so that a copy of the treatise does actually exist in Pietros handwriting. The story, however, has long since been disproved; yet to show the great interest which Pietro took in the work, and the[11] ready assistance he gave to his friend, a letter to him from Beccaria, with respect to the second edition, deserves mention, in which Beccaria begs him not only to revise the spelling correctly, but generally to erase, add, and correct, as he pleases. It would appear that he was already tired of literary success, for he tells his friend, that but for the motive of preserving his esteem and of affording fresh aliment to their friendship, he should from indolence prefer obscurity to glory itself.Moreover, if, as was said, our feelings are limited in quantity, the greater respect men may have for things outside the laws, the less will remain to them for the laws themselves. From this principle the wise administrator of the public happiness may draw some useful consequences, the exposition of which would lead me too far from my subject, which is to demonstrate the uselessness of making a prison of the State. A law with such an object is useless, because, unless inaccessible rocks or an unnavigable sea separate a country from all others, how will it be possible to close all the points of its circumference and keep guard over the guardians themselves? A man who transports everything he has with him, when he has done so cannot be punished. Such a crime once committed can no longer be punished, and to punish it beforehand would be to punish mens wills, not their actions, to exercise command over their intention, the freest part of human nature, and altogether independent of the control of human laws. The punishment of an absent man in the property he leaves behind him would ruin all international commerce,[225] to say nothing of the facility of collusion, which would be unavoidable, except by a tyrannical control of contracts. And his punishment on his return, as a criminal, would prevent the reparation of the evil done to society, by making all removals perpetual. The very prohibition to leave a country augments peoples desire to do so, and is a warning to foreigners not to enter it.

While standard calandria type evaporation systems are widely used as the typical concentration evaporator by the various food and chemical industries, we have delivered many of those systems as finishing concentration evaporators especially for sugar solutions and starch syrups.

THREE:It is of interest to trace some of the practical results which followed Beccarias treatise during the thirty years that he lived after its publication; that is, from the year 1764 to 1794.It is the specific crime, not the fact that it is a second or third felony, which is injurious. Neither a community nor an individual suffer more from the commission of a crime by a man who commits it for the second time than from its commission by a man who has never committed it before. If two brothers are each robbed of a pound apiece on two several occasions, the one who is robbed each time by the same criminal suffers no more than the one who is robbed each time by different criminals. Still less is the public more injured in one case than in the other. Therefore the former brother is entitled for his second loss to no more restitution than the other, nor has any more claim on society for the infliction of a severer punishment on his behalf than that inflicted for the second loss of his brother.
  • Enables flexible operation with little influence from variations in load and raw solution concentrations because of an adequate amount of solution being held within the system. These systems are also suitable for batch type burning evaporators.
  • Concentrations can be controlled within product specifications by the cascade control using the concentrations of concentrated solution and the raw solution supply and also by the arithmetic control of raw solution concentrations, etc. (Result for sugar solutions: 75±0.2wt%)
  • High-viscosity solutions and solutions that may crystallize can also be utilized by installing a propeller in the evaporator as a forced circulation system.
THREE:

This is a process example of a device that continuously and simultaneously concentrates two types of waste liquid with a single high-efficiency steam compressor.

THREE:
  • By evaporating the steam using a mechanical compressor and reusing it, almost no heating steam is alomost required except the time of start-up, so large energy savings can be expected.
  • By combining with a thin film falling heat exchanger that does not raise the boiling point due to the liquid depth, it is possible to utilize the temperature difference of the compressor at the maximum.
  • Since the residence time and heating time are short and the holding amount is small, starting and stopping can be performed in a short time.
  • It will prevent scale adhesion in the can that the evaporator is divided into two parts, and that the supply of the undiluted solution is alternately switched over a fixed period of time to perform heat concentration.
