Show Vacutcm Storage Preserves Furs A novel use for a vacuum has been discovered by a St. Louis storage man. An experimental room has been built In which rugs and other household furnishings fur-nishings are stored. The air Is then partly exhausted, with the result that all insect life, such as moths, Is unable to exist. Mice also die quickly, as there Is little oxygen in the air. The room Is 8 by 8 by 8 feet with walls eight inches thick and built of non-porous non-porous concrete. Glass peepholes are arranged on two sides for studying the effect of the vacuum on Insect and animal ani-mal life. A steel door is provided with special hinges and four screws with handles are used to hold the door securely se-curely until the air exhaustion begins. After a partial vacuum has been created cre-ated the door Is drawn so tight from outside air pressure that no locks or fastenings are needed. Scientific American. |
