摘要： An apparatus for regulating the fiber concentration of a fiber suspension during transport of the fiber suspension through a conduit which comprises a variable speed-controlled electric motor driving a pump for impelling the fiber suspension through the conduit to an outlet of the latter. A system is provided for obtaining a measure of the power supplied by the motor to the pump and for dividing this measure by a signal proportional to the flow rate of the fiber suspension in the conduit. The resulting signal, which is proportional to the fiber concentration in the fiber suspension, is employed to regulate the speed of the pump motor.

摘要： A soft-serve freezer operates in a first mode, with both the auger and compressor operating, and a second energy saving mode in which only the refrigeration compressor operates. The control circuit monitors the power level to the auger to control the consistency of the mix. When the mix achieves a selected consistency, the auger discontinues its mixing function. Signal lights are provided to indicate when it is necessary to actuate the auger to obtain the desired consistency prior to dispensing the product and indicate that the mix has achieved the desired consistency.

摘要： A viscosity measuring system especially useful to pollution and chemical process control applications. A variable gain amplifier drives a magnetic coil which causes a torsion member to oscillate. The amplitude of the oscillations is sensed by a transducer, and converted to a DC voltage by an amplitude monitoring circuit. The DC voltage, which represents the instantaneous amplitude of mechanical oscillation, is compared to a reference DC voltage which represents the desired amplitude of oscillation. The resulting error signal is utilized to control the gain of the amplifier in such a manner that the amplitude of mechanical oscillation is maintained constant and equal to the desired amplitude. The viscosity of the fluid in which the torsion member is immersed is obtained by providing an output signal which is a measure of the power provided by the amplifier to the magnetic coil in order to maintain the desired constant amplitude of oscillation. Preferably, the output signal is obtained from the voltage developed across a resistor in series with the magnetic coil.
摘要翻译：一种特别适用于污染和化学过程控制应用的粘度测量系统。可变增益放大器驱动导致扭转构件振荡的电磁线圈。振荡器的振幅由换能器感测，并通过幅度监视电路转换成直流电压。将表示机械振荡的瞬时幅度的直流电压与表示期望的振荡幅度的参考DC电压进行比较。所得到的误差信号用于以这样的方式控制放大器的增益，使得机械振荡的幅度保持恒定并等于期望的幅度。通过提供输出信号来获得扭转构件浸入其中的流体的粘度，该输出信号是放大器向磁性线圈提供的功率的量度，以便保持期望的恒定振幅。优选地，从与电磁线圈串联的电阻器上产生的电压获得输出信号。
