    • An audio signal distortion detection device for simplifying the detection of harmonic distortion to aid in setting an amplifier's gain control to match an audio source unit's output voltage. The audio signal distortion detection device generally includes a housing having a plurality of status indicators thereon for indicating the status of an audio signal being fed into the housing's audio input. By utilizing a scaling circuit and processing unit, the present invention may be configured to detect four audio frequencies and compare DC levels of the frequencies to each other to determine if harmonic distortion is present. A distortion illuminator will illuminate when such distortion is detected and thus significantly reduce the effort required to setting an amplifier's gain control.
    • 一种音频信号失真检测装置,用于简化谐波失真的检测,以帮助设置放大器的增益控制以匹配音频源单元的输出电压。 音频信号失真检测装置通常包括其上具有多个状态指示器的壳体,用于指示馈送到壳体的音频输入中的音频信号的状态。 通过利用缩放电路和处理单元,本发明可以被配置为检测四个音频并将频率的DC电平彼此比较,以确定是否存在谐波失真。 当检测到这种失真时,失真照明器将亮起,从而显着降低设置放大器增益控制所需的工作量。

    • The present invention discloses a reactor (100) for manufacturing carbon black, said reactor (100) comprising flow guide means (110) provided between a fuel burner (106) and an air inlet (108) for altering the flow path of combustion air entering at the air inlet (108) to result in a better mixing between the fuel and the combustion air, thereby, producing higher temperature hot combustion gases which are subsequently received in a reaction chamber (104) where they react with a carbonaceous feedstock to produce carbon black. The reactor (100) of the present invention increases the carbon black production by 5-20%. Further, the positioning of the flow guide means (110) stabilizes the flame from the fuel burner (106) to maintain it along the reactor axis, thus, increasing the life of the refractory lining (114).
    • 本发明公开了一种用于制造炭黑的反应器(100),所述反应器(100)包括设置在燃料燃烧器(106)和空气入口(108)之间的流动引导装置(110),用于改变进入的燃烧空气的流动路径 在空气入口(108)处导致燃料和燃烧空气之间更好的混合,由此产生更高温度的热燃烧气体,其随后被接收在反应室(104)中,在反应室中它们与碳质原料反应以产生碳 黑色。 本发明的反应器(100)将炭黑的产量提高5-20%。 此外,流动引导装置(110)的定位使来自燃料燃烧器(106)的火焰稳定,以使其沿着反应器轴线保持,从而增加耐火衬层(114)的寿命。
