TWO:On Tuesday night, the 12th of December, 1740, there was a very splendid masked ball in Berlin. The king and queen were both present. The mind of the king was evidently preoccupied, though he endeavored to assume an air of gayety. Privately quitting the ball at a late hour, he set out, early in the morning, to place himself at the head of forty thousand troops whom he had assembled near the Silesian frontier. A small escort only accompanied him. It was a cold winters day. Driving rapidly, they reached Frankfort that night, sixty miles distant. In the dawn of the next day the king was again upon the road, and, after a drive of forty miles, reached Crossen, a border town, where he established his head-quarters.The shrewd foresight of Frederick, and his rapidly developing military ability, had kept his army in the highest state of discipline, while his magazines were abundantly stored with all needful supplies. It was written at the time:

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:While in health and prosperity, quaffing the wines of Frederick, he was an avowed infidel, and eagerly joined the ribald companions of the king in denouncing all religion as the fanaticism of weak minds. But in these hours of pain, of loneliness, and of approaching death he could find no consolation in the teachings of philosophy. He sent for two Christian ministers to visit497 him daily, and daily had the Bible read to him. It was a death-bed repentance. Bitterly he deplored a wasted life. Sincerely he seemed to embrace the doctrines of Christianity.143 He died, after a lingering sickness, far from home and friends, on the 27th of July, 1759.
  • 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:135 As the king was about to take leave of his child, whom he had treated so cruelly, he was very much overcome by emotion. It is a solemn hour, in any family, when a daughter leaves the parental roof, never to return again but as a visitor. Whether the extraordinary development of feeling which the stern old monarch manifested on the occasion was the result of nervous sensibility, excited by strong drink or by parental affection, it is not easy to decide. Wilhelmina, in a few words of intense emotion, bade her father farewell.Still, on the whole, the siege progressed favorably. Large supplies of food and ammunition were indispensable to Frederick. Thirty thousand hungry men were to be fed. A constant bombardment rapidly exhausts even abundant stores of powder, shot, and shell.
