TWO:Leaving out problems of mechanism in forging machines, the adaptation of pressing or percussive processes is governed mainly by the size and consequent inertia of the pieces acted upon. In order to produce a proper effect, that is, to start the particles of a piece throughout its whole depth at each blow, a certain proportion between a hammer and the piece acted upon must be maintained. For heavy forging, this principle has led to the construction of enormous hammers for the performance of such work as no pressing machinery can be made strong enough to execute, although the action of such machinery in other respects would best suit the conditions of the work. The greater share of forging processes may be performed by either blows or compression, and no doubt the latter process is the best in most cases. Yet, as before explained, machinery to act by pressure is much more complicated and expensive than hammers and drops. The tendency in practice is, however, to a more extensive employment of press-forging processes.

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:The dark eyes were gleaming in the white face. Despite her racking head and her tired limbs, Leona was gradually summoning back her latent forces. Her hand no longer trembled, the wild beating of her heart was stilled.

• Equipment costs can be reduced.

• Alarm and interlock mechanism.

THREE:Very large divisions marched from Vis�� to the pontoon bridge in the direction of Tongres. After the Li��ge forts had been taken the bridge might be passed in perfect safety. All day long troops came along that road without interruption. I could quite see that the soldiers who were at Vis�� the previous day, and brought about the conflagration, were gone, for they had left their traces behind. All along the road lay parts of bicycles, shoes, instruments, toys, and so on, everything new77 and evidently looted from the shops. Very valuable things were among them, everything crushed and smashed by the cavalry horses, the clumsy munition and forage waggons, or the heavy wheels of the guns.
