TWO:The next morning Frederick crossed the river to Reitwein, on the western bank. Here, during the day, broken bands of his army came in to the number of twenty-three thousand. It would seem that a night of refreshing sleep had so far recruited the exhausted energies of the king that he was enabled to look a little more calmly upon the ruin which enveloped him. He that day wrote as follows from Reitwein to General Schmettau, who was in command of the Prussian garrison at Dresden:While these scenes of war and intrigue were transpiring, no one knowing what alarming developments any day might present, Vienna was thrown into a state of terror in apprehension of the immediate approach of a French army to open upon it all the horrors of a bombardment. The citizens were called out en masse to work upon the fortifications. The court fled to Presburg, in Hungary. The national archives were hurried off to Gr?tz. The royal family was dispersed. There were but six thousand troops in the city. General Neipperg, with nearly the whole Austrian army, was a hundred and fifty miles distant to the north, on the banks of the Neisse. The queen, on the 10th of September, assembled at Presburg the Hungarian Parliament, consisting almost exclusively of chivalric nobles renowned in war. The queen appeared before them with her husband, the Grand-duke Francis, by her side, and with a nurse attending, holding her infant son and heir. Addressing them in Latin, in a brief, pathetic speech, she said:

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:The difficulties I had last campaign were almost infinite, there were such a multitude of enemies acting against me. Pomerania, Brandenburg, Saxony, frontiers of Silesia, were alike in danger, and often all at one time. If I escaped absolute destruction, I must impute it chiefly to the misconduct of my enemies, who gained such advantages, but had not the sense to follow them up. Experience often corrects people of their blunders. I can not expect to profit by any thing of that kind on their part in the course of this campaign.148
