摘要： A stirring element (10), especially a gasing stirring element for stirring liquids and introducing a gas, preferably air, to the liquids. The stirring element has a hub (12) for attachment to a stirring shaft and a support disk (14) joined to the hub (12), a plurality of stirring blades (16) being attached to a peripheral edge of the support disk (14). To achieve a low output power coefficient, each stirring blade (16) is made of a wedge-shape that is directed in the direction of rotary motion of the stirring element (10). Preferably, radially inner end sections (22, 24) of two sides (18, 20) of the stirring blade (16) are angled relative to sides (18, 20) outwardly with reference to the direction of rotary motion of the stirring element (10). The stirring element (10) simplifies gas feed and prevents clogs. By providing the support disk (14) with a conical shape having a ring of teeth (26) on its outer edge, a uniform distribution and good dispersion of the gas bubbles is obtainable.

摘要： An auto-aspirating, rotational dispersion device for gases and liquids with a rotating hollow shaft employed for gas suction and gas channels communicating with said hollow shaft to openings in the gas channels that are positioned at intervals over the circumference of the device, at which openings the gas and liquid are mixed. The device is distinguished by the fact that the gas being dispersed flows in a manner separate from the liquid, from the hollow shaft through the gas channels and is mixed with the liquid outside of the device.

摘要： The present invention generally pertains to an agitating element for agitating low-to-medium-viscosity liquids. The agitating element comprises an inner main blade and an outer side blade, and the two blades are integrally constructed. The main blade is angled with respect to the rotation axis of the agitating element, while the side blade is angled with respect to the rotation plane of the agitating element. The agitating element according to the current invention enables high hydraulic efficiency especially in a vertical direction so as to accomplish thorough mixing of the material with a minimal energy input.

摘要： In order to achieve improved release characteristics in the case of a protective device for power supply lines, a protection release method is proposed in which at least one signal (i, u) is supplied to a filter device (3, 16), and a release decision is made as a function of its output signal (SA, Z). If the conditions are insufficient for release, a change is made to the filter characteristics. The filter device (3, 16) in this case preferably comprises adaptive filters or combinations of filters. In a further refinement, a fuzzy region, which is used as the release criterion, is formed as a function of a change in the output signal.

摘要： A method and a device for detecting and correcting a saturated current profile of a current transformer in a particularly simple and reliable way, initially uses a number of logic inquiries derived from sampled values of the present current signal profile to detect a start of saturation on the basis of a pattern recognition. An end of saturation is subsequently determined, likewise with the aid of a number of logic inquiries. A saturation signal is then formed from a combination of the logic inquiries. In the case of the detection of saturation, the current sampled values are discarded, and an image of the unsaturated current signal profile is reconstructed from a number of sampled values determined ahead of the time of detection of saturation.
