EGGS MAY BE UNSCRAMBLED

Scrambled eggs can be unscrambled, turned back into whites and yolks again, by a new unmixing machine designed for he oil industry and shown at the International Petroleum Exposition at Tulsa, kkhema, says the Winnipeg ‘Free Press.’ Its first use is a short cut to extract fine motor oils from murky petroleum. The unmixer does one of those things which seemingly can’t happen, forcing two 1 quids to flow in the same stream but one in tic opposite direction to the other. A whirling turLine, going 1,800 revolutions a minute, does it. Instead of being an ordinary turbine, this one b shaped inside like a snail shell. Its interior passage winds from the centre outward in spirals. A cross section, would look like a clock spring. it tal es two liqirds at one time. The only necessity is that they be something that won’t mix, like oil and water. The water goes in at the inner end of the whirling spiral. The centrifugal force pins this water against the outer wall of the spiral passage and pushes it along towards the cuter end, where itemerges. Meanwhile • the kerosene is forced into the spiral from the opposite end by a pres .lire pump, which keeps it moving in the opposite direction from the water. Being lighter Ilian the water, it flows over the surface. It travels like any wind-blown substance floating on water. T;e centrifugal force keeps separating the liqu'ds so t\nt they emerge conipletcv separated and from opposite ends of i the spiral. i
