Abstract: An agitator ball mill having a milling chamber and an agitator having a rotatably mounted and driven agitator shaft and accelerators arranged thereupon, wherein the accelerator that is arranged furthest downstream, that is, the accelerator closest to the milling material outlet, lengthens axially and extends along the axial length of the sieve.

Abstract: An agitator ball mill for finely grinding or dispersing material has a cylindrical or conical grinding chamber for accommodating grinding bodies and for accommodating the material which is to be ground or dispersed. It also has an inlet, which is arranged at one end of the grinding chamber, an agitator, which extends in the axial direction into the grinding chamber and has agitating means, and a product outlet for the ground or dispersed material, the product outlet being arranged at the other end of the grinding chamber. Arranged in a central region at the outlet end of the grinding chamber is a gas outlet through which gaseous components, but not grinding bodies, can be discharged out of the grinding chamber.

Abstract: In order to obtain a simple construction of an electricity meter (1), the invention provides that the meter comprises a highly integrated input module (3a, 3b, 3c) in which an analog-digital converter (5a, 5b) and an output module (7a) are integrated. A multiplying means (21) can optionally be integrated. Such an input module (3a, 3b, 3c), in combination with conventional components, especially microprocessors, makes it possible to produce an electricity meter which comprises a simple construction and which is of a single-phase and multi-phase type (also for a plurality of consumers).

Abstract: A temperature compensation circuit for a power measurement device includes an input sensor, with a temperature-dependent transmission factor (K.sub.H,T), connected to a signal processor with a temperature-dependent transmission factor (K.sub.S,T). Transmission factor (K.sub.S,T) of the signal processor is inversely proportional to a temperature-dependent reference voltage (U.sub.R,N,T), which is inputted to the signal processor in order to render the combined transmission factor (K.sub.H,T .multidot.K.sub.S,T) temperature independent. To accomplish this, a temperature coefficient value of reference voltage (U.sub.R,N,T) must be equal to the sum of a temperature coefficient value of transmission factor (K.sub.H,T) and a temperature coefficient value of transmission factor (K.sub.S,T). The desired temperature coefficient value of reference voltage (U.sub.
