Title: Forced intake & exhaust type combustor
Inventor: TADOKORO MINORU
IPC: F23L17/16
Filed: 1978-02-22
Abstract: PURPOSE: To make possible intake and exhaust intake and exhaust tubes by such a construction that the exhaust gas is jetted into the room by the use of a combustion fan and the exhaust gas in the room is released to outdoors by the use of a separately provided exhaust fan having a larger capacity than the combustion fan.  
     CONSTITUTION: When the combustor's body 1 is turned into operation an intake & exhaust fan 11 begins to rotate for normal operation. At this time, air for combustion is taken from the air in the room to be sucked through an incoming air receiver mouth 2 while the exhaust gas produced by the combustion is jetted into the room out of the exhaust nozzle 3, directed to the exhaust gas reveiver mouth 16 leading  to the intake & exhaust part 4. At the same time, the air in the room is sucked  through the exhaust gas receiver mouth 16 by the action of the intake & exhaust  fan 11 and released to outdoors from the exhaust cylinder 10. Compared with a  combustor of conventional forced intake & exhaust type, this can spare an intake  tube and an exhaust tube to assure a greater installation margine and the extent  where movement is allowed after installation, is also wider.

Abstract: PROBLEM TO BE SOLVED: To obtain coating liquid having always stabilized concn. by calculating the concn. of the coating liquid, automatically pouring water in the case of being high concn. and supplementing the coating agent in the case of being low concn. SOLUTION: The coating liquid B adjusting the concn. in a stirring machine 1 is stored in a dipping tank 6 through a coating liquid supplying tube 5 and a mold is dipped into the stored coating liquid B' to apply the coating liquid on the surface of the mold. Then, the coating liquid 13 in the stirring machine 1 is sampled with a densimeter 7 to measure the density. Based on this measurement, the concn. of the coating liquid B is calculated. It is judged whether the concn. is suitable value or not, i.e., whether the concn. is dencer or thinner than the regulating value. In the case of being dense concn., water is poured by automatically opening a valve 2a of a water pouring pipe 2 with a control unit 9, and in the case of being thin concn., the coating agent is supplemented by automatically opening a coating agent supplemental value 3a.  By this method, the man-hour of the coating work and the control man-hour can be reduced by automating the applying of the coating agent.
