Abstract

911,454. Automatic control of mills. INSTITUT FURWARMETECHNIK UND AUTOMATISIERUNG DER SILIKALHUTTENINDUSTRIE W.T.I. March 22, 1960, No. 10190/60. Class 38 (4). The grinding noise of mill 7 is picked up by microphone 1 and passed to amplifier 2, the noise of the mill being measured both in terms of frequency and amplitude. The output voltage of the amplifier is transmitted through rectifier 3 to regulator 4 for controlling the supply of grist to the mill. The characteristic of the amplifier is such that the variation of its output voltage corresponds, after rectification, to the sum of the frequency and amplitude variations of the noise. The desired characteristic is obtained through resistance-capacitance, resistance-inductance elements, or through oscillator circuits, and these elements may be used to suppress irrelevant ranges of the noise-frequency spectrum. Non-linear resistors or non-linear valves in the amplifier may be used to suppress irrelevant ranges of amplitude of the noise signal.
