TWO:Two days before Frederick reached Brieg, a column of his army, under General Schwerin, which had advanced by a line parallel to the Oder, but several miles to the west, encountering no opposition, reached Ottmachau, a considerable town with a strong castle on the River Neisse. This was near the extreme southern border of Silesia. The Austrian commander, General Browne, had placed here also a garrison of sixteen hundred men,232 with orders not to yield upon any terms, for that re-enforcements should be speedily sent to them. A slight conflict ensued. Twelve of the Prussians were killed. This was the first blood which was shed. A delay of three days took place, when four cannon were brought up, and the gates, both of the town and of the castle, were blown open. The garrison offered to withdraw upon the terms proposed in the summons to surrender. The king was sent for to obtain his decision. He rebuked the garrison sternly, and held all as prisoners of war. The officers were sent to Cüstrin, the common soldiers to Berlin.

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 Saturday, the 25th of October of this year, George II., King of England, died. The poor old gentleman, who had been endowed with but a very ordinary share of intelligence, was seventy-seven years of age. On Monday he had presided at a review of troops in Hyde Park. On Thursday he stood upon the portico of his rural palace in Kensington to see his Guards march by for foreign service. Saturday morning he rose at an early hour, took his cup of chocolate as usual, and, opening his windows, said the morning was so fine he would take a walk in his garden. It was then eight oclock. His valet withdrew with the cup and saucer. He had hardly shut the door when he heard a groan and a fall. Hurrying back, he found the king upon the floor. Faintly the death-stricken monarch exclaimed, Call Amelia, and instantly died. Monsieur,I believe that it is of the last importance that I should write to you, and I am very sad to have things to say which I ought to conceal from all the earth. But one must take that bad leap, and, reckoning you among my friends, I the more easily resolve to open myself to you.
