Abstract: A device and a method are described for regulating a generator, by means of which device or method an increased generator output power can be achieved either in that the excitation current may have a value which is above the rated excitation current, or in that the generator is dimensioned such that overheating could occur under unfavourable circumstances. In order that this does not occur, even under unfavourable circumstances, the temperature is measured, preferably in the regulator, and the temperature at critical points is calculated from this temperature, taking into account typical parameters. If an unacceptably high temperature is recognised, the excitation current is reduced by suitable measures to such an extent that the maximum permissible temperature is not exceeded. …<IMAGE>…

Abstract: In connection with implant work on the dentine, use is made of a machining instrument which is provided with an attachment part (31) for attachment to a rotary unit. The machining instrument can alternatively be applied in an extension unit which in turn can be applied to the rotary unit in a corresponding manner to the machining instrument. The extension unit has a thickened central section (17c) which is provided with a recess or opening (24), in which an inclined surface (29) is arranged. In the applied position of a machining instrument, one surface (30) of its attachment part is set against the inclined surface (29). A rotationally-fixed cooperation is present between the extension unit and the machining instrument. Moreover, a locking effect is achieved between the extension unit and the machining instrument as a result of a secure wedging effect obtained by means of the inclined surface. The rotary movement transmitted from the rotary unit to the extension unit is in turn transmitted to the machining instrument, which moreover is secured in the longitudinal displacement direction.
