Abstract

479,738. Supplying purified air to enclosures. EUGSTER, J. July 12, 1937, No. 19256. Convention date, Aug. 7, 1936. [Class 137] An anti-poison gas enclosure or shelter c is connected by pipes b, controlled by valves d, with a number of vessels a of air-pervious material, the air supplied to the enclosure being filtered by passage through the soil between the vessels and the ground surface. Each vessel has a drain through which water penetrating the sides can flow back into the sub-soil. The vessels may be embedded in gravel to ensure the passage of air, and the pipes b are connected to an air pump (not shown) to draw the air through the soil and supply it to the enclosure.
