TWO:Still Wusterhausen was but a hunting-lodge, which was occupied by the king only during a few weeks in the autumn. Fritz had many playmateshis brothers and sisters, his cousins, and the children of General Finkenstein. To most boys, the streams, and groves, and ponds of Wusterhausen, abounding with fish and all kinds of game, with ponies to drive and boats to row, with picturesque walks and drives, would have been full of charms. But the tastes of Fritz did not lie in that direction. He does not seem to have become strongly attached to any of his young companions, except to his sister Wilhelmina. The affection and confidence which united their hearts were truly beautiful. They encountered together some of the severest of lifes trials, but heartfelt sympathy united them. The nickname which these children gave their unamiable father was Stumpy.In his epistle Frederick had expressed the opinion that428 there was no God who took any interest in human affairs. He had also repeatedly expressed the resolve to Wilhelmina, and to Voltaire, to whom he had become partially reconciled, that he was prepared to commit suicide should events prove as disastrous as he had every reason to expect they would prove. He had also urged his sister to follow his example, and not to survive the ruin of the family. Such was the support which the king, in hours of adversity, found in that philosophy for which he had discarded the religion of Jesus Christ.

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:ATTACK UPON NEISSE. My dearest Sister,I am in despair that I can not satisfy158 my impatience and my duty, to throw myself at your feet this day. But, alas! dear sister, it does not depend upon me. We poor princes are obliged to wait here till our generals come up. We dare not go along without them. They broke a wheel in Gera. Hearing nothing of them since, we are absolutely forced to wait here. Judge in what a mood I am, and what sorrow must be mine. Express order not to go by Baireuth or Anspach. Forbear, dear sister, to torment me on things not depending on myself at all.
