Title: Method for detecting filling state of filler in filling frame
Inventor: KOSHIHARA TOSHIO
IPC: G01N25/72
Filed: 1988-02-23
Abstract: PURPOSE:To make it possible to detect the filing state without destruction readily, by heating or cooling a filling frame from the center side, photographing the outer surface of the filling frame with an infrared-ray camera, and detecting the filing state of a filler as an infrared-ray image. CONSTITUTION:A hot-medium supplying pipe 4 is provided in a pipe column 1 filled with concrete beforehand. When the filling state of the concrete 3 is detected, the pipe column 1 is heated from the center side by feeding the heating medium of liquid or gas, e.g., hot water, through the pipe 4. When a cavity 10 due to incomplete filling of the concrete 3 is present in contact with the inner surface of a steel pipe 2 as an outer frame at this time, heat stream is transferred to the steel pipe 2 through the cavity at the incompletely filled part where the cavity 10 is present. Therefore, the transfer of the heat stream is slow. After the pipe column 1 is heated from the center side, the outer surface of the pipe column 1 is photographed with an infrared-ray camera 11 that senses the temperature difference on the surface. Then, the infrared-ray image of the cavity 10 is obtained on the image of the outer surface of the pipe column 1. Thus, the filling state of the concrete 3 can be detected by utilizing the infrared-ray image.

Abstract: PURPOSE: To prevent afterburn by flowing exhaust gas in a duct fitted with a flame extinguisher for intercepting downstream propagation of the flame only when the operation is liable to afterburn, e.g. when the engine decelerates or when the vehicle descends a slope.  
     CONSTITUTION: As a vehicle carrying an engine 1 decelerates or descends a slope, a throttle valve 13 closes full and a negative pressure prevails in a suction pipe 2. Driven by the negative pressure, a diaphragm 10e and a stopper shaft 10g rise to communicate ports 10j and 10m. As a negative pressure prevails in a negative pressure chamber 9d of a negative pressure device 9, a diaphragm 9b moves rightward to change over a selector valve 7 through a working shaft 9c, closing a duct 6. The exhaust gas flows through a duct 5, a flame in the exhaust gas is extinguished by a flame extinguisher 5a, and the flame is prevented from downstream propagation. As the engine 1 operates normally, the valve 7 is changed over to close the duct 5.
