 Washed Air for the Carbureter

An atmospheric stabilizer draws air from the exhaust manifold

���The hot air is carried through flexible tubing from the manifold surface to a dampener containing water and wicking, where it is thoroughly humidified

��Showing how the water is auto- matically fed from the overflow of the radiator tank to the stabilizer

��AUTO MO- BILE driv- ers are well aware that the en- gine works more efficiently and more satisfactorily in the early morn- ing and late eve- ning when the hu- midity is high. Hence, it occurred to one inventor, to humidify the air as it is admitted to the carbureter and to do it whenever it was desirable. The atmospheric sta- bilizer, as the device is called, maintains the air at a uniform temperature, as it is drawn from (but not out of) the exhaust manifold, the hottest exposed part of the engine.

The hot air is conveyed through flex- ible tubing from the manifold surface to a dampener containing water and a wicking, which is automatically fed from the overflow of the radiator tank, as the accompanying drawing illustrates. Be- cause of the arrangement of the wicking, the hot air must puss through water on the

��way to the damp- ener. This not on- ly humidifies it, but also washes it free of dirt and grit.

The principal re- sult of providing air properly hu- midified and at un- iform temperature, is a smooth run- ning, efficient en- gine. A secondary worthwhile result is a lessened con- sumption of gaso- line.

��Bullets Made of Paper Do More Damage Than Metal Ones

INCREDIBLE as it may seem, bullets made of paper will do much damage. A recent experiment has shown that a paper bullet, after having passed through six pieces of tin one foot apart, buckled them, A similar experiment made with metal bullets showed that they passed through the same thicknesses of tin but they made only a small clean-cut hole.
