TWO:The correspondence carried on between Frederick and Voltaire, and their mutual comments, very clearly reveal the relations existing between these remarkable men. Frederick was well aware that the eloquent pen of the great dramatist and historian could give him celebrity throughout Europe. Voltaire was keenly alive to the consideration that the friendship of a monarch could secure to him position and opulence. And yet each privately spoke of the other very contemptuously, while in the correspondence which passed between them they professed for each other the highest esteem and affection. Frederick wrote from Berlin as follows to Voltaire:Early in October the allies planned an expedition for the capture of Berlin. The city had no defenses but weak palisades, which were garrisoned by but twelve hundred men. General Czernichef led a column of twenty thousand Russians, General509 Lacy another of fifteen thousand Austrians, and General Soltikof a third column of twenty thousand more.

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:To whose continual sluggishness and strange want of concertto whose incoherency of movements, languor of execution, and other enormous faults, we have owed, with some excuse for our own faults, our escape from destruction hitherto.The prince was withdrawn, and placed in a room where two sentries watched over him with fixed bayonets. The king malignantly assumed that the prince, being a colonel in the army and attempting to escape, was a deserter, whose merited doom was death. General Mosel urged the king not to see his son again, as his presence was sure to inflame his anger to so alarming a pitch. The father did not again see him for a year and three days.
