TWO:Peter III. had been left an orphan, and titular Duke of Schleswig-Holstein, when eleven years of age. His mother was a daughter of Peter the Great. His aunt, the Czarina Elizabeth, who had determined not to marry, adopted the child, and pronounced him to be her heir to the throne. Being at that time on friendly terms with Frederick, the Empress Elizabeth had consulted him in reference to a wife for the future czar. It will be remembered that the king effected a marriage between Peter and Sophia, the beautiful daughter of a Prussian general, Prince of Anhalt-Zerbst, and at that time commandant of Stettin. His wife was sister to the heir-apparent of Sweden. Carlyle, speaking of this couple, says:

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:
  • Equipment costs can be reduced.
  • Operating costs can be reduced.
  • Maintenance costs can be reduced.
  • Any change in raw material and product can be easily addressed.
  • Large amounts can be treated in a small area.
  • Separation and cleaning are easy because of the simple structure.
  • Simplified control
  • This equipment can be operated in synchronization with external devices.
  • Alarm and interlock mechanism.
THREE:Sire,Yesterday I was in terrible alarms. The sound of the cannon heard, the smoke of powder visible from the steeple-tops here, all led us to suspect that there was a battle going on. Glorious confirmation of it this morning. Nothing but rejoicing among all the Protestant inhabitants, who had begun to be in apprehension from the rumors which the other party took pleasure in spreading. Persons who were in the battle can not enough celebrate the coolness and bravery of your majesty. For myself, I am at the overflowing point. I have run about all day announcing this glorious news to the Berliners who are here. In my life I have never felt a more perfect satisfaction. One finds at the corner of every street an orator of the people celebrating the warlike feats of your majestys troops. I have often, in my idleness, assisted at these discourses; not artistic eloquence, it must be owned, but gushing full from the heart.In September, 1749, Madame Du Chatelet, the divine Emilie of Voltaire, suddenly died. The infidel philosopher seemed much grieved for a time. Frederick, who never fancied Madame Du Chatelet, was the more eager, now that she was out of the way, that Voltaire should come to Sans Souci, and aid him in his literary labors. A trivial incident occurred at this time worthy of record, as illustrative of the character of the king. At the close of the year 1749 there had been a review of Austrian troops at M?hren. It was not a very important affair, neither the empress queen nor her husband being present. Three380 Prussian officers made their appearance. It was said that they had come to inveigle soldiers to desert, and enlist under the banners of Prussia. They were peremptorily ordered by the Austrian authorities to leave the ground. Frederick, when he heard of it, said nothing, but treasured it up.
