    摘要: A spinning apparatus having a spinning section for forming yarn by applying a rotating air current of predetermined air pressure to a supplied fiber bundle and twisting the yarn while opening an end of the fiber bundle, and having a piecing section for reverse threading a spun yarn end into that spinning section. The spinning apparatus has a high pressure application member for applying high pressure air at a pressure higher than the aforementioned predetermined air pressure to such fiber bundle during the predetermined time after the spun yarn end is reverse threaded into the spinning section. The high pressure application member includes a first air circuit for supplying the aforementioned predetermined air pressure, a second air circuit that supplies air at a pressure higher than the aforementioned predetermined air pressure and a change-over member between the first and second air circuits.

    摘要: It is necessary for maintaining a good assimilating characteristic of microorganisms upon organic matter in an aeration tank to control a gas flow rate and a return sludge flow rate to optimum values. To this effect, it is necessary to know a concentration of organic matter or a organic load. In the present invention, it is confirmed that carbon dioxide (CO.sub.2) or nitrous oxide (N.sub.2 O) in an exhaust gas from the aeration tank has a correlation with it, and the aeration tank is controlled as N.sub.2 O or CO.sub.2 as an index. Furthermore, it is confirmed that CO.sub.2 formation rate has a good correlation with COD or BOD in the upstream half section of the aeration tank, whereas N.sub.2 O formation rate has a good correlation with COD or BOD in the latter half section thereof along sewage flow direction, and more improved control can be attained by a combination of both CO.sub.2 and N.sub.2 O indices.
