TWO:The city took fire in many places; magazines were consumed; the ducal palace was wrapped in flames. Nearly fifteen thousand cannon-balls, and over two thousand bombs, were hurled crashing through the thronged dwellings. Many of the Austrian guns were silenced. General Piccolomini, who was intrusted with the defense of the place, could stand it no longer. On the 4th of May he raised above the walls the white flag of surrender. The gallant general was treated magnanimously. He was invited to dine with Frederick, and, with the garrison, was permitted to retire to Neisse, pledged not to serve against the Prussians for two years. The town had been nearly demolished by the war-tempest which had beat so fiercely upon it. Frederick immediately commenced repairing the ruins and strengthening the fortifications.The king kicked him, and struck him several heavy blows with his cane. He was hit repeatedly in the face, and blood gushed from the wounds. With his own hands the king tore from Kattes breast the cross of the Order of Saint John. After this disgraceful scene the interrogatory commenced. Katte confessed all the circumstances of the princes intended escape, but denied that there had been any design against the king or the state. His own and the princes letters were examined, but nothing was found in them to criminate either. Katte was then100 remanded to prison. Wilhelmina, after receiving the grossest possible insults from her father, who accused her, in coarsest terms, of being the paramour of Lieutenant Katte, was ordered to her room. Two sentries were placed at her door, and directions were given that she should be fed only on prison fare.

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:We now enter upon the third Silesian war, usually termed in history The Seven Years War. For four years Frederick had been aware that a coalition was secretly forming against him. Maria Theresa wished, with ardor which had never for one moment abated, to regain Silesia. All the other European powers, without exception, desired to curb Frederick, whose ambition they feared. They were well aware that he was taking advantage of a few years of peace to replenish his treasury, and to enlarge his army for new conquests. As we have before stated, Frederick, by bribery, had fully informed himself of the secret arrangements into which Austria, Russia, Poland, and other powers were entering for the dismemberment of his realms. It is in vain to attempt to unravel the intricacies of the diplomacy which ensued.The severity of discipline in the Prussian army was dreadful. The slightest misdemeanor was punished mercilessly. The drill, exposure, and hardships in the camp made life to the soldier a scene of constant martyrdom. Desertion was almost impossible. The only avenue of escape was suicide. In the little garrison at Potsdam, in ten years, over three hundred, by self-inflicted death, escaped their miseries. Dr. Zimmerman states that it not unfrequently happened that a soldier murdered a child, and then came and gave himself up to justice. They thought that if they committed379 suicide they would be subject to eternal punishment. But the murdered infant was sure to go to heaven, and the murderer would have time to repent and make his peace with God.

THREE:It would seem that if ever there were an excuse for suicide it was to be found here. But what folly it would have been! Dark as these days were, they led the prince to a crown, and to achievements of whose recital the world will never grow weary. Fritz, goaded to madness, again adopted the desperate resolve to attempt an escape. A young Englishman, Captain Guy Dickens, secretary of the British embassador, Dubourgay, had become quite the intimate friend of the Crown Prince. They conferred together upon plans of escape. But the precautions adopted by the father were such that no plan which they could devise seemed feasible at that time. Fritz confided his thoughts to his friend, Lieutenant Keith, at Berlin.
