TWO:One of them was standing against a curtain of black satin embroidered with gold; muslin that might have been a spider's web hardly cast a mist over her sheenless skin, pale, almost white against the glistening satin and gold, all brightly lighted up. With a large hibiscus flower in her hand she stood in a simple attitude, like an Egyptian painting, then moved a little, raising or lowering an arm, apparently not seeing the passers-by who gazed at herlost in a dream that brought a strange green gleam to her dark eyes.

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:A carriage with four horses, and servants in dark green livery thickly braided with silver, and gold turbans with three raised corners very like the cocked hats of the French Guards, were standing in the Court of Honour. The little princess took a seat between her father and me. To drive out she had put on an incredible necklace with bosses of diamonds and heavy emerald pendants. With her talismans round her neck in little gold boxes, with this necklace of light, and rings of precious stones in her ears, she looked like a too exquisite idol, motionless and silent. It was not till we were returning and the falling night hid her glittering jewels that she chirped a few words, and consented to give me her hand, and even sang a few crystal notes of a favourite song. A little princess of seven years who can already read and write, sew[Pg 69] and embroider, sing in time, and dance as lightly, I should fancy, as a butterfly with her tiny feet, that fidget in her gold slippers when she hears the musicthough, frightened lest the Rajah should make her dance before me, she denied it altogethera little princess, an only child, whom her father takes with him everywhere that she may see something of the world before she is eleven years old, for after that she will never leave her mother's zenana but to marry and be shut up in another harem.
  • Equipment costs can be reduced.
