Description

Patent No. 420 describes the adaptability of heating air with the heat of exhaust air, in which channels are formed with the help of wooden bars / employees for spreading metal sheets separating exhaust air from fresh air. In the proposed adaptation, instead of wooden ones The bar uses stamped metal gaskets or pipes that are riveted, welded, or freely lying on both sides of each of the sheets.

In FIG. 1 shows a section through a tool in the case of stamped gaskets; FIG. 2 view of it; FIG. 3 shows a section through a device in the case of a pipe; FIG. 4th view of the latter.
