TWO:Then, under a portico in front of us, a man began to undress. He threw off his dhoti and his sarong, keeping on his loin-cloth only. With outstretched arms he placed a heavy copper pot full of water on the ground, took it up between[Pg 171] his teeth, and without using his hands tilted his head back till the water poured all over him in a shower, which splashed up from the pavement, sprinkling the spectators in the front row. Next he tied his dhoti round the jar, which he refilled, and fastened the end to his long hair. Then, simply by turning his head, he spun the heavy pot round him. It looked as if it must pull his head off, but he flung it faster and faster till he presently stopped.At a turn in the road the view opened out to a[Pg 249] distant horizon; the plain of Peshawur, intensely green in contrast with the rosy tone of the foreground; and far away the Himalayas, faintly blue with glaciers of fiery gold in the sun, against a gloomy sky where the clouds were gathering.

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:And then night, the real night, transparently blue and luminous with stars, appeared above the last cloud that vanished with the last clap of thunder. Unspeakable freshness and peace reigned over nature, and in the limpid air the mountain-chains, the giant Himalayas, extended to infinity in tones of amethyst and sapphire. Nearer to us, lights sparkled out in the innumerable huts built even to the verge of the eternal snows, on every spot of arable ground or half-starved grass land.And once more in a barge on the Ganges. The atmosphere seemed faintly iridescent, like mother-of-pearl, the silence serenely lulled by the distant sound of a flute. The palaces and temples, reflected in the still water, looked in the distance like forts crowned with turrets of gold, and their little windows like loopholes. The broad stairs of the quays, where the priests' umbrellas glitter, assumed a spacious, unfamiliar dignity, the red colour shading paler towards the bottom, where it was washed off by the lapping Ganges, looking as though a fairy hanging of gauze were spread under the wavelets in honour of the Apsaras and the divinities of the river.
