TWO:Next morningso far, so high on the horizon! I saw a pink spot; then, as day broke, the rose colour spreadbroader, lower, turned paler, then to white, and the Himalayas lay before me in blinding glory of size and light. Kinchinjunga, at a measureless distance, looked in the clear air as if it were quite close; and round the sovereign giant other giants rent their wrappings of cloud, an amphitheatre of peaks of dazzling whiteness lost against the sky, and almost insensibly fading away behind the vapour that rolled up from the abysses, grew[Pg 148] thicker, and settled into a compact mass over the lost summits, hiding the nearer heights and shrouding Darjeeling in opaque white fog.The carriage of the Rajah of Palitana awaited us this morning at Songad. As an escort two sowars in long blue cloaks and red turbans, their guns slung behind them, galloped by our vehicle. On each side of the road lay fields of scorched grass, quite burnt and very fine, glistening like silk, reflecting the sun as far as we could see.

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:One after another I made my salaam to Siva, seated on a peacock; to Ganesa, looking calm and knowing; to Parvati, riding a bull; to Siva again, this time pinning a dragon to the ground with a fork, a writhing reptile with gaping jaws and outspread wings; the same god again, with a child in[Pg 121] his arms; and again, holding his leg like a musket up against his shoulder with one of his four hands, the other three lifting a bull, a sceptre, and a trophy of weapons above his head.
