TWO:The majority of mankind lack that vigour which is equally necessary for the greatest crimes as for the greatest virtues; whence it would appear, that both extremes are contemporaneous phenomena in nations[162] which depend rather on the energy of their government and of the passions that tend to the public good, than on their size and the constant goodness of their laws. In the latter the weakened passions seem more adapted to maintain than to improve the form of government. From which flows an important consequence, namely, that great crimes in a nation do not always prove its decline.A few years earlier Beccaria could have imagined no greater honour. To associate with the philosophers he so highly reverenced, as a philosopher himself, what greater happiness or reward could he have asked? Yet when it came there was no charm in it; and it was with difficulty he could be persuaded to go. For with his love for distinction there came into competition the love of his wife, and if he preferred her company to that of the wisest and wittiest celebrities of Paris, who shall say that he was the worse philosopher for that?

Hydrocyclone (liquid cyclone)02

A hydrocyclone (liquid cyclone) injects treatment solution into stationary equipment to perform separation, classification, and concentration, and is an innovative separator with a very simple structure and no drive unit.

Structure of a hydrocyclone (liquid cyclone)

A suspension containing fine particles of several micrometers or more is supplied to a cylindrical container circumferentially at high speed. And as a result it starts to rotate and a centrifugal force is generated. At this time a gravitational acceleration of several tens of thousands of G is generated in the circumferential direction, and thus leading to fast sedimentation and concentration of the fine particles. The separated concentration can be freely selected by changing the supply rate (supply pressure and flow rate) and the flow ratio of the outlet. Our hydrocyclone (liquid cyclone) was designed and manufactured to classify and concentrate fine particles, and so has a small element.

THREE:
  • Equipment costs can be reduced.
  • Operating costs can be reduced.
  • Maintenance costs can be reduced.
  • Any change in raw material and product can be easily addressed.
  • Large amounts can be treated in a small area.
  • Separation and cleaning are easy because of the simple structure.
  • Simplified control
  • This equipment can be operated in synchronization with external devices.
  • Alarm and interlock mechanism.
THREE:That force, similar to the force of gravitation, which constrains us to seek our own well-being, only admits of counteraction in proportion to the obstacles[198] opposed to it. The effects of this force make up the confused series of human actions; if these clash together and impede one another, punishments, which I would call political obstacles, prevent bad effects from resulting, without destroying the impelling cause, which lies in the sensibility inseparable from humanity; and the legislator, in enacting them, acts the part of a clever architect, whose function it is to counteract the tendency of gravitation to cause a building to fall, and to bring to bear all the lines which contribute to its strength.[19]
