Optical monitoring of warp yarn continuity in weaving process

摘要

The coal stove has a frame from which a set of components are suspended or supported. These include an ash pan (4), a grate (5) , a basket (6) and a hopper above the basket. Outlet pipes from the hopper for the combustion gases lead to a flue (9), while the air inlet (12) is below th ash pan. A shutter (14) in the inlet is controlled by a thermostat (20) in the flue. A rise in the temp. of the combustion gases progressively closes the shutter.
