TWO:On the 20th of April, Frederick, having secretly placed his army in the best possible condition, commenced a rapid march upon Prague, thus plunging into the very heart of Bohemia. He advanced in three great columns up the valley of the Elbe and the Moldau. His movements were so rapid and unexpected that he seized several Austrian magazines which they had not even time to burn. Three months provisions were thus obtained for412 his whole army. The first column, under the king, was sixty thousand strong. The second column, led by General Bevern, numbered twenty-three thousand, horse and foot. The third, under Marshal Schwerin, counted thirty-two thousand foot and twelve thousand horse. On the 2d of May the banners of Frederick were seen from the steeples of Prague. They appeared floating from the heights of the Weissenberg, a few miles west of the city. At the same time, the other two columns, which had united under Marshal Schwerin, appeared on the east side of the Moldau, upon both banks of which the city is built.There are several letters still remaining which Lieutenant Katte wrote to his friends during those hours of anguish in which he was awaiting his death. No one can read them without compassionate emotion, and without execrating the memory of that implacable tyrant who so unjustly demanded his execution. The young man wrote to the king a petition containing the following pathetic plea:
THREE:Fritz had now attained eighteen years of age, and Wilhelmina twenty-one. Fritz was very fond of music, particularly of his flute, upon which he played exquisitely, being, however, careful never to sound its notes within hearing of his father. A celebrated music-master from Dresden, by the name of Quantz, was his teacher. He came occasionally from Dresden and spent a week or two at Potsdam, secretly teaching the young prince.67 The mother of Fritz was in warm sympathy with her son, and aided him in all ways in her power in this gratification. Still it was a very hazardous measure. The fierce old king was quite uncertain in his movements. He might at any hour appear at Potsdam, and no one could tell to what lengths, in case of a discovery, he might go in the intensity of his rage. Fritz had an intimate friend in the army, a young man of about his own age, one Lieutenant Katte, who, when Fritz was with his music-teacher, was stationed on the look-out, that he might give instant warning in case there were any indications of the kings approach. His mother also was prepared, when Quantz was at Potsdam, promptly to dispatch a messenger to her son in case she suspected his father of being about to turn his steps in that direction.
THREE:The doge and senate were brought to terms. They seized the beautiful Barberina, placed her carefully in a post-chaise, and, under an escort of armed men, sent her, from stage to stage, over mountain and valley, till she arrived at Berlin. The Venetian embassador was then discharged. The young English gentleman, James Mackenzie, a grandson of the celebrated advocate, Sir George Mackenzie, eagerly followed his captured inamorata, and reached Berlin two hours after Barberina. The rumor was circulated that he was about to marry her.The army, writes Prince Charles, mournfully, was greatly dilapidated. The soldiers were without clothes, and in a condition truly pitiable. So closely were we pursued by the enemy that at night we were compelled to encamp without tents.
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.
