摘要： PURPOSE:To maintain the specified outflow rate of a molten metal by evacuating the inside of a ladle when the height of the molten metal in the ladle is higher than a reference height and pressurizing the same when the height is lower than the reference height. CONSTITUTION:The optional height of the molten metal in the ladle is determined as the reference height and the height of the molten metal in the ladle during outflow is detected. The detected height and the reference height are compared and the molten metal is evacuated until both heights are made equal when the detected height is larger than the reference height. The molten metal is pressurized in the opposite case so that always specified outflow is executed. The degassing in the molten metal is executed by the evacuation.
摘要翻译：目的：当钢包中的熔融金属的高度高于参考高度时，通过抽出钢包内部来保持熔融金属的指定流出速率，并且当高度低于参考高度时对其进行加压。构成：钢包中熔融金属的可选高度被确定为参考高度，并且在检测到流出期间钢包中的熔融金属的高度。比较检测到的高度和参考高度，并且当检测到的高度大于参考高度时，将熔融金属抽真空直到两个高度相等。在相反的情况下，熔融金属被加压，从而总是执行规定的流出。通过抽真空来进行熔融金属的脱气。

摘要： PURPOSE: To dephosphorize coke forreductive refining of metal oxide, etc. by a simple process inexpensively, by carrying out dephosphorization wherein coke is treated with a specific acid.
CONSTITUTION: Porous coke containing phosphorus caused by external matters, existing in a spot way microscoplically, is immersed in an acid (e.g., HCl, H
2 SO
4 , HNO
3 , etc.) at ≤5pH at room temperature for 2hr, so that phosphorus is extracted and removed. Rise in temperature of the solution can extremely increase dephosphorization speed.

摘要： PURPOSE:To heat water and increase the temperature thereof to supply hot-water by a method wherein cold water is circulated between a heat accumulating tank and a heat collector by an automatic water feeding device. CONSTITUTION:The cold water, flowed out of the opening of a water feeding pipe 20 by the operation of a foot valve 21 by a predetermined amount, overflows from the lower notched opening 19 of a hollow column body 18 and enters into the heat collecting pipes 6, 6... through a circulating pipe 10 and a connecting pipe 7, thereafter, heat exchange between a heat accumulating body or asphalt 4 is effected and the water flows into the heat accumulating tank 13 through the connecting pipe 8 and the circulating pipe 11 under being heated. The heat accumulating body or the asphalt 4 receives not only the solar heat direction on the surface thereof but also the reflected solar heat by a reflecting plate 14, capable of changing the angle of inclination thereof and installed in the device to increase the amount of collected heat and whereby the heat collecting efficiency of the device may be improved remarkably in winter especially. The water, thus heated, enters into the heat accumulating tank 15 through the connecting pipe 8 and the circulating pipe 11 and returns into the heat collector 9 again, thus the temperature thereof is increased under repeating circulation while hot-water may be supplied to necessary places through a hot-water supplying pipe 2 when it is used.
摘要翻译：目的：通过自动给水装置通过蓄热池和集热器之间的冷水循环的方法来加热水并提高其供应热水的温度。构成：通过脚踏阀21的操作使给水管20的开口流出预定量的冷水从中空柱体18的下切口19溢出并进入集热管 6，6 ...通过循环管10和连接管7，之后，进行蓄热体或沥青4之间的热交换，并且水通过连接管8和循环管流入蓄热罐13 11被加热。蓄热体或沥青4不仅接受其表面上的太阳热方向，而且受到反射板14的反射太阳热，能够改变其倾斜角并安装在装置中以增加收集的量特别是在冬季，装置的集热效率明显提高。被加热的水通过连接管8和循环管道11进入蓄热槽15，并再次返回到集热器9中，因此在重复循环的同时，其温度可以被提供到需要的热水使用时通过热水供给管2进行放置。
