TWO:181 Sire, I can not bear these reproaches, which I do not deserve. I have tried, for the relief of your majesty, all the remedies which art can supply, or which nature can admit. If my ability or my integrity is doubted, I am willing to leave not only the university, but the kingdom. But I can not be driven into any place where the name of Hoffman will not be respected.

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:On the 15th of March Frederick left Berlin for Silesia. Stopping to examine some of his works at Glogau and Breslau, he reached Neisse on the 23d. On the 29th he dismissed the Old Dessauer, with many expressions of kindness and sympathy, to go home to recover his health.Her majesty, all in tears, complained of her situation. The king is nigh losing his senses on account of the differences with Hanover; goes from bed to bed in the night-time, and from chamber to chamber, like one whose brains are turned. Took a fit at two in the morning lately to be off to Wusterhausen. Since his return he gives himself up entirely to drink. The king will not suffer the prince royal to sit next his majesty at table, but obliges him to go to the lower end, where things are so ordered that the poor prince often rises without getting one bit, insomuch that the queen was obliged two days ago to send, by one of the servants who could be trusted, a box of cold fowls and other eatables for his royal highnesss subsistence.
  • 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:Wusterhausen, where the young Crown Prince spent many of these early years of his life, was a rural retreat of the king about twenty miles southeast from Berlin. The palace consisted of a plain, unornamented, rectangular pile, surrounded by numerous outbuildings, and rising from the midst of low and swampy grounds tangled with thickets and interspersed with fish-pools. Game of all kinds abounded in those lakelets, sluggish streams, and jungles.
