TWO:His companions had no heart to witness the bloody execution of their friend and brother-officer. The chaplain, Müller, who had accompanied the condemned to Cüstrin, and also Besserer, the chaplain of the garrison there, were either obliged by their official position, or were constrained by Christian sympathy, to ride by his side in the death-cart to the scaffold. Of the rest of his friends he took an affectionate leave, saying, Adieu, my brothers; may God be with you evermore! He was conveyed to the rampart of the castle dressed in coarse brown garments precisely like those worn by the prince.Indeed, it would seem that, at the time, Voltaire must have been very favorably impressed by the appearance of his royal host. The account he then gave of the interview was very different from that which, in his exasperation, he wrote twenty years afterward. In a letter to a friend, M. De Cideville, dated October 18th, 1740, Voltaire wrote:

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:
  • 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:Frederick, ever regardless of fatigue and exposure for himself, never spared his followers. It was after midnight of the 28th when the weary column, frostbitten, hungry, and exhausted, reached Olmütz. The king was hospitably entertained in the fine palace of the Catholic bishop, a little, gouty man, writes Stille, about fifty-two years of age, with a countenance open and full of candor.At eleven this day I went to the council-chamber for the third time, and desired Secretary Hartoff to prevail with the ministry to allow me to speak with them, and communicate what the King of Prussia had ordered me to propose. Herr von Hartoff gave them an account of my request, and brought me, for answer, that I must wait a little, because the ministers were not yet all assembled; which I did. But after having made me stay almost an hour, and after the president of the council was come, Herr von Hartoff came out to me and repeated what he had said yesterday, in very positive and absolute terms, that the ministers were resolved not to see me, and had expressly forbid him taking any paper at my hands.
