TWO:Again, on the 19th of February, 1732, the Crown Prince wrote from Cüstrin to Baron Grumkow. From his letter we make the following extracts:In the midst of ftes, operas, and suppers, my secret negotiation advanced. The king allowed me to speak to him on all subjects. I often intermingled questions respecting France and Austria in conversations relating to the ?neid and Livy. The discussion was sometimes very animated. At length the king said to me, Let France declare war against England, and I will march. This was all I desired. I returned as quickly as possible to the court of France. I gave them the same hopes which I had myself been led to entertain at Berlin, and which did not prove delusive.
THREE:It appears, moreover, that Fritz devoted himself very assiduously to his military duties, earnestly studying the art of war, and making himself familiar with the achievements of the most renowned commanders. His frugal father allowed him but a very meagre income for a princenot above four thousand five hundred dollars a year. With this sum it was scarcely possible to keep up even the appearance of such an establishment as belonged to his rank. Such glimpses as we get of his moral and social developments during this period are not favorable. He paid no respect to the claims of religion, and was prone to revile Christianity and its advocates. He was particularly annoyed if the chaplain uttered, in his sermons, any sentiments which the prince thought had a bearing against the sensual indulgences and the wild amusements of himself and his companions. On one occasion the chaplain said in his sermon, There was Herod, who had Herodias to dance before him, and he gave her John the Baptists head for her pains.
THREE:Frederick William was in high spirits. Many distinguished strangers were invited to his court, and they were received with great magnificence. There were costly and showy entertainments, served by six-and-twenty blackamoors, bands of music, with much pomp of etiquette, and reviews of the giant guard and of the marvelously drilled army. Preparations were made for a review of great splendor on Monday, the 28th of May. The Prince of Baireuth was invited, though neither the queen nor Wilhelmina were aware of it. At the early hour of seven oclock of the preceding evening the king went to bed, that he120 might be fresh for the review on the morrow. His high-born guests were left to be entertained by the queen and the princess. Just as they were passing in to supper, the sound of carriage wheels, approaching the foot of the grand staircase, was heard in the court-yard. As that was an honor conferred only upon princes, the queen was a little surprised, and sent to inquire who had arrived. To her consternation, she found that it was the Prince of Baireuth.Grumkow led me to the young man in gray. Coming near, I recognized him, though with difficulty. He had grown much stouter, and his neck was much shorter. His face also was much changed, and was no longer as handsome as it had been. I fell upon his neck. I was so overcome that I could only speak in an unconnected manner. I wept, I laughed like a person out of her senses. In my life I have never felt so lively a joy. After these first emotions were subsided I went and threw myself at the feet of the king, who said to me aloud, in the presence of my brother,
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.
