Title: Pouring furnace
Inventor: OOMORI TSUGIHARU
IPC: B22D39/06
Filed: 1980-05-14
Abstract: PURPOSE: To reduce oxidation of molten metal and lower running costs by recompressing exhaust air from a tightly closed molten metal storage chamber and tapping molten metal in a tapping furnace in which the molten steel is tapped by injecting compressed air into said storage chamber and the tapping is stopped by exhausting the compressed air.  
     CONSTITUTION: The compressed air in a high-pressure tank 8 is fed into the upper part of a tightly closed molten metal storage chamber 2 by regulating the pressure with a control device 9. A molten metal surface 7 is forced downward by the compressed air to force out molten metal 6 through a tapping path 3 opened to the atmosphere in the position higher than the surface 7, thereby pouring the same into a mold. Next, the feeding-in of the compressed air is stopped by the device 9, and the air in the chamber 2 is exhausted to a low pressure tank 11 by an exhaust valve 10, whereby the tapping is stopped. The air in the tank 11 is passed through a cooler 12, a drain separator 13, and a filter 14 and is compressed by a compressor 15, thence it is passed through a cooler 16, and is fed into the tank 8, from which it is against injected into the upper part of the chamber 2 by the device 9 for the purpose of tapping. Hence, the oxygen in the air fed into the chamber 2 is oxidized by the initial tapping and is eliminated, thus there is no need for using any inert gas.

IPC: F02D23/00
Filed: 1981-04-28
Abstract: PURPOSE:To enable to control the ignition timing in the optimum condition at all times by a method wherein the ignition timing is controlled by a number of revolution and a suction pressure when the knocking is not being generated while it is controlled by the suction pressure upon the knocking is being generated but not by the same which is lowered when the knocking is being generated, in the internal-combustion engine in which a supercharging pressure is lowered upon knocking. CONSTITUTION:In case a decision circuit 21 decides that the knocking is not being generated by the signal of a knocking sensor 1, the signals of a revolving number sensor 2 and a suction pressure sensor 3 are inputted into an ignition timing operating circuit 25. On the other hand, when the decision circuit 21 outputs a knocking signal A into a supercharging pressure control unit 22 and a breaking circuit 23, the supercharging pressure is reduced under a constant opening degree signal of a throttle sensor 15 and the output of the sensor 3 is also cut off simultaneously. Accordingly, the revolving number signal and the suction pressure signal before the cut-off which is being held in a memory circuit 24 are inputted into an operating circuit 25. According to this input, the ignition timing is brought to the side of delayed angle than the limit of knocking. In case there is a change in the opening degree signal of the sensor 15, the breaking circuit 23 is stopped regardless of the existence or non-existence of the signal A and the operation is effected by a new suction pressure.

The light is then allowed to impinge on a sample metal 7 set in an atmosphere to be measured through a polarizer 5 and a quarter-wave plate 6. By rotating the polarizer 5 and an analyzer 8, a point at which light detected with a photomultiplier 9, i.e., reading of the meter of a detector 10 is minimized is searched. On the basis of 2 angles Δ and Ψ showing the minimum point, changes of Δ and |δΨ/δt| with the passage of time are obtd. When the extent of Δ changed is ≤ about 5° and that of |δΨ/δt| exceeds about 0.3°/h or becomes unmeasurable, it is judged that pitting corrosion occurs on the metallic surface.
