摘要： A spray unit positioned between roll stands in the path of a steel workpiece advancing in a predetermined substantially horizontal pass line in a continuous hot-rolling mill, includes a pair or spaced spray chambers longitudinally aligned in tandem. The steel workpiece passes through a spray section in each of the spray chambers. As the steel workpiece passes through the spray sections, water is sprayed by high pressure nozzles onto the entire surface of the steel workpiece to reduce the temperature thereof. Guard means are provided to prevent damage to the high pressure nozzles. The steel workpiece is aligned axially in the spray chambers by positioning means. The sprayed water is rapidly removed from the spray sections to prevent the formation of a water bath in the spray chambers.

摘要： Wastewaters, from a coke oven by-product plant, containing cyanides and objectionable complex organic compounds are treated by a high density sludge process. The wastewaters are mixed with an aqueous high calcium lime slurry and a portion of the sludge formed in the process, which portion is recycled in the process. The aqueous high calcium lime slurry and the portion of recycled sludge are mixed for a time to obtain a uniform mix. A solution containing iron values is added to the uniform mix. Iron cyanide compounds and a portion of the complex organic compounds are precipitated. The precipitate is flocculated and is passed to a settling tank wherein the precipitate settles out to form a high density sludge.

摘要： Signal conditioner apparatus multiplies electronic material gaging signal by one or more predetermined variable scaling factors to compensate for variations in other material properties which affect the gaged property. For example, material thickness gaging signal variations caused by material temperature variations are compensated for by simultaneously feeding the thickness signals through two adjustable-gain amplifiers preset at separate values which establish an adjustable range of temperature compensation. Amplifier outputs are proportioned in response to a material temperature measurement made during material gaging, thereby providing a single temperature compensated material thickness signal at an output. Material composition compensation is provided in combination with temperature compensation by first feeding the thickness signal through a single presettable-gain amplifier. All amplifier gains are preset or controlled from a data source which correlates compensation requirements with temperature and composition effects on material thickness gaging.
摘要翻译：信号调理装置将电子材料测量信号乘以一个或多个预定的可变比例因子以补偿影响测量特性的其它材料特性的变化。例如，由材料温度变化引起的材料厚度测量信号变化通过同时馈送厚度信号通过两个可调节增益放大器进行补偿，这两个可调增益放大器以分立的值预设，建立温度补偿的可调节范围。响应于在材料测量期间进行的材料温度测量，放大器输出成比例，从而在输出端提供单个温度补偿材料厚度信号。通过首先通过单个可预置增益放大器馈送厚度信号，结合温度补偿提供材料组成补偿。所有的放大器增益都是从数据源预设或控制的，数据源将补偿要求与材料厚度测量的温度和成分效应相关联。
