TWO:There are temples all along the shore, poor little structures for the most part. On the walls gaudy borders of crude colour serve to frame chromo-lithographs representing the principal events of the Vedas. There are but one or two sanctuaries built of marble, and very rarely have the idols any precious jewels.

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:Beyond Siliguri, where we left the main line, a little toy railway, going very slowly, jostles the travellers across rice plantations and woods of giant trees, under whose shade tree-ferns expand on the banks of the streams. By the side of the water springs are hung prayers written on strips of rice-paper that flutter in the wind from the shrubs and bamboos, mingling with the blossoms of rhododendron and funkia, spots of bright colour showing against the forest of mighty cedars and sycamores and gloomy palms. Clinging to the highest branches, orchids like birds are to be seen, and from bush to bush hang bright green threads covered with white stars, tangled into hanks and hooked on to every thorn. The vegetation of banyans, ph?nix, and other tropical plants gradually becomes mixed with oak, box, and plane trees, and then disappears altogether as we get higher; and presently, as we pass through a belt of great dark firs, the shrubs, the mosses, and even the flowers are those of Europe. Higher up, the mountain side is mapped out into lines and squares, green and russet, looking from a distance[Pg 146] like ribbed velvet; these are the tea plantations. The horizon grows broader, spreading away and out of sight towards the vision-like mountains forming the outposts of the Himalayas; up to the very verge of the eternal snows they are cultivated in the same rib-like strips, all tea plantations; and amid the shrubs are the little factories where the precious leaves are dried, and villages of little homesteads lost among the greenery, or peeping through the opalescent haze, intensely blue under the pure, cold sky and crude sunshine. The natives here wear skins with the fur inside; the leather outside is patterned with red or blue cloth. Men and women alike go about in felt boots, which give them an unsteady and straddling gait.
  • 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:The road from Cawnpore to Gwalior makes a bend towards central India across a stony, barren tract, where a sort of leprosy of pale lichen has overgrown the white dust on the fields that are no longer tilled. There is no verdure; mere skeletons of trees, and a few scattered palms still spread their leaves, protecting under their shade clumps of golden gynerium.
