TWO:We now enter upon the third Silesian war, usually termed in history The Seven Years War. For four years Frederick had been aware that a coalition was secretly forming against him. Maria Theresa wished, with ardor which had never for one moment abated, to regain Silesia. All the other European powers, without exception, desired to curb Frederick, whose ambition they feared. They were well aware that he was taking advantage of a few years of peace to replenish his treasury, and to enlarge his army for new conquests. As we have before stated, Frederick, by bribery, had fully informed himself of the secret arrangements into which Austria, Russia, Poland, and other powers were entering for the dismemberment of his realms. It is in vain to attempt to unravel the intricacies of the diplomacy which ensued.

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:The pampered duchess sent by the French minister to Berlin a complimentary message to Frederick. He disdainfully replied: The Duchess of Pompadour! who is she? I do not know her. This was an offense never to be forgiven.
