Title: Ductile metal coated iron metal product and method
Inventor: ALLEGRA LOUIS
IPC: F01N13/16
Filed: 1980-12-15
Abstract: This invention is directed to an improved zinc containing metallic coated ferrous product, particularly sheet and strip, which is resistant to intergranular penetration by zinc and embrittlement of the ferrous base. Use of such zinc containing metallic coated ferrous product in elevated-temperature service, such as found with certain appliances and automotive exhaust components, is enhanced by the coated products of this invention. The resistance to embrittlement of the zinc containing metallic coated ferrous base, when subjected to elevated service temperatures, is achieved by the use of a high-phosphorus containing steel base. For a plain content steel base, a phosphorus content of at least 0.020% by weight, preferably at least 0.030%, and more preferably at least 0.039% was found sufficient to render such zinc-alloy coated ferrous base resistant to embrittlement by zinc. By use of such high phosphorus ferrous base, for the reception of a zinc containing alloy coating, an improved metallic coated ferrous product has been found which resists intergranular penetration by zinc and embrittlement of the ferrous base. Such coated product has extended service life at temperatures above about 450 DEG  F. (232 DEG  C.) and when restored to room temperature possesses a high degree of ductility.

Abstract: PROBLEM TO BE SOLVED: To confirm the upper and lower and right and left parts in the pipe displayed on a monitor and to make it possible to judge whether the running pipe is the iron pipe or not from the monitor image at the same time by containing movable water and a display body in the cavity part of the hollow ring of a state display part provided in the image pickup region in front of an image pickup means. SOLUTION: A guide 6 makes the mud and the like to be accumulated at the connecting part of a pipe and in the pipe easy to ride over when the image pickup device in the pipe advances. A state display part 7 has water 8 and a display body 9 in a cavity part 7a of a hollow ring body made of resin such as transparent vinyl chloride and is used for up and down indication and the confirmation of an iron pipe. The display body 9 comprises a floating part for imparting buoyancy and a magnet part attached to the float part. Furthermore, since the state display part 7 is located in the image pickup range in front of a camera body 1, the display part 7 is imaged on a monitor together with the state in the pipe. The water 8 tends to be located in the lower side in the cavity part 7a all the time by the gravity.  The display part 9 floating on the water is always located at the lower side together with the water. The fact that the pipe is the iron pipe can be also recognized by the downward movement of the magnet part.

Title: Open type kerosene burner
Inventor: HANADA EIICHIRO
IPC: F23N1/02
Filed: 1987-07-16
Abstract: PURPOSE:To sharply reduce the generation of a smell on extinction, by a method wherein, after an extinguishing command is issued, an amount of air for combustion fed is shifted to a feed amount larger by a given amount then an amount prevailing during optimum combustion once, and extinguishing motion is effected. CONSTITUTION:After an extinguishing command is issued, a control device 10 leaves a fuel feed amount as it is, and shifts only an amount of air for combustion fed to a value larger by a given amount than a fuel feed amount prevailing during optimum combustion. At a point of time when shifting is completed, a pump 3 is brought into a stop to effect extinguishing motion. When an amount of air for combustion is low, fuel gas stays in the vicinity of the inner wall of a carburetor 6, gas concentration is high, and subsequent fuel particles are difficult to evaporate. When an amount of air for combustion is increased based on the same fuel feed amount, fuel gas is efficiently blown off by means of an air flow, and since a scanning effect is improved, rapid evaporation can be continued. As noted above, since after an extinguishing command and after an evaporation delay amount is brought into a lowermost state through shift of an amount of air for combustion fed, whereby extinguishing motion is effected; an intermediate decomposition product is prevented from generating, and so is much smell.
