Abstract

462,452. Filtering air. STAUBER, J. Aug. 6, 1935, No. 3620/37. Divided out of and addition to 460,901, [Group X]. [Class 8 (ii)] [Also in Group X] Air for use in gas-protected rooms is drawn by suction through the soil which acts as a filter and is forced into the rooms. A pit 1 is excavated from the ground, and the sides are lined with wire netting 3, or with bricks or concrete provided with air holes. A layer of gravel 4 is arranged below and outside the side walls. A fan 7 driven by a motor 6 draws air from the pit and forces it through a delivery pipe 9 to the enclosure. The cover of the pit is provided with a window 10.
