TWO:Would you prevent crimes, then see that enlightenment accompanies liberty. The evils that flow from knowledge are in inverse ratio to its diffusion; the benefits directly proportioned to it. A bold impostor, who is never a commonplace man, is adored by an ignorant people, despised by an enlightened one. Knowledge, by facilitating comparisons between objects and multiplying mens points of view, brings many different notions into contrast, causing them to modify one another, all the more easily as the same views and the same difficulties are observed in others. In the face of a widely diffused national enlightenment the calumnies of ignorance are silent, and authority, disarmed of pretexts for its manifestation, trembles; whilst the rigorous force of the laws remains unshaken, no one of education having any dislike to the clear and useful public compacts which secure the common safety, when he compares the trifling and useless liberty sacrificed by himself with the sum-total of all the liberties sacrificed by others, who without the laws might have been hostile to himself. Whoever has a sensitive soul, when he contemplates a code of well-made laws, and finds that he has only lost the pernicious liberty of injuring others, will feel[246] himself constrained to bless the throne and the monarch that sits upon it.Thus before his death Beccaria saw torture almost entirely abolished in Europe, and a general tendency spreading to follow the spirit of the changes he advocated in other details of criminal law. Probably no other theorist ever lived to witness so complete an adoption of his principles in practice, or so thorough a transformation of the system he attacked. It is possible that he but gave body and voice to ideas of change already widely prevalent in his time; but the[38] merit of a man belongs none the less to himself, who changes the instability of public opinion into an active and solid force, and who gives distinct expression to the longings vaguely felt by a multitude.

Hydrocyclone (liquid cyclone)01

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:CHAPTER XXIV. THE MEASURE OF PUNISHMENTS.
