摘要： A device for determining the filling level in a container including an oscillator with two rotational oscillation elements (10, 12) of the same resonance frequency which oscillate oppositely. The oscillation elements (10, 12) are arranged coaxially, have a common rotational axis, masses of the same size, and a common mass center. Both oscillation elements (10, 12) are fixed to a common membrane which serves as a retraction spring, through which a common drive of both oscillation elements (10, 12) is possible.

摘要： A device for the determination of the charging level in a container has a vibrator on which two torsional vibrators (10, 12) of the same resonance frequency vibrate in an opposite way. The vibration elements (10, 12) are arranged coaxially and have a common center of rotation (20) which is located in the center of a diaphragm (14) serving as a return spring for the outer element (10). The inner element (12) is designed in the shape of a rod and has a tapering (17) in the area of the center of rotation (20) acting as a return spring. Owing to the design according to the invention, a charging level determination is possible with goods charged of a high and of a low density whereby the detection sensitivity is almost independent of the clamping conditions of the vibrator.

摘要： For the uniform treatment of bulk material by means of a gas the bulk material is fluidized in a rotating container (101) in order to be mixed by the rotation thereof. In the case of heating the bulk material the rotation of the container is expediently interrupted at periodic intervals. A transport device is preferably provided in the interior of this container, in particular in the form of a worm or screw flight (20) of irregular pitch--related to one rotation in order to be able to precisely determine the dwell time through the mechanical transport. This screw (20) is preferably constructed as a two-start screw (FIG. 6).
摘要翻译：为了通过气体均匀处理散装材料，散装材料在旋转容器（101）中流化，以便通过其旋转而混合。在加热散装材料的情况下，容器的旋转以周期性间隔方便地中断。运输装置优选地设置在该容器的内部，特别是以与旋转相关的不规则节距的蜗杆或螺旋桨（20）的形式，以便能够通过机械运输精确地确定停留时间。该螺钉（20）优选构造为双重启动螺钉（图6）。

摘要： A filling level measuring probe detects the filling level in a container by suppression of an oscillator by contact with a filling material. The oscillator consists of a hollow body 16, which can be connected through a shaft 14 and a screw-in part 12 with a container wall 10 and is set in oscillation with oscillations in the radial direction over a crosspiece 20 mounted in hollow body 16 by means of an electromechanical transducer 26 which is mounted on crosspiece 20. The oscillations are converted by a second electromechanical transducer 28 into an electric signal, of which the amplitude is changed with suppression of the oscillations as a result of contact of the hollow body 16 with the filling material.
