TWO:It was during the year 1838 that the Chartists became an organised body. The working classes had strenuously supported the middle classes in obtaining their political rights during the agitation for the Reform Bill, and they expected to receive help in their turn to obtain political franchises for themselves, but they found Parliament indifferent or hostile to any further changes in the representation, while the middle class, satisfied with their own acquisitions, were not inclined to exert themselves much for the extension of political rights among the masses. The discontent and disappointment of the latter were aggravated by a succession of bad harvests, setting in about 1835. The hardships of their condition, with scanty employment and dear provisions, the people ascribed to their want of direct influence upon the[456] Government. This gave rise to a vigorous agitation for the extension of the franchise, which was carried on for ten years. In 1838 a committee of six members of Parliament and six working men prepared a Bill embodying their demands. This was called the "People's Charter." Its points were six in number:First, the extension of the right of voting to every male native of the United Kingdom, and every naturalised foreigner resident in the kingdom for more than two years, who should be twenty-one years of age, of sound mind, and unconvicted of crime; second, equal electoral districts; third, vote by ballot; fourth, annual Parliaments; fifth, no property qualification for members; sixth, payment of members of Parliament for their services.

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:
  • Classification and concentration for the manufacture of inorganic powder materials
  • Classification of ceramic materials
  • Removal of fine particles, including iron powder
  • Removal of fine particles from pigments
  • Removal of fine organic particles from solvents
