摘要:
Method of regulating a water level of a dam installation having a plurality of turbine generator units arranged to generate electrical power, wherein at least some of the plurality of turbine generator units are arranged at least one of one above another and one beside another so as to form at least one turbine generator module. The method includes regulating, at least to some extent, the water level to a predefinable set point by starting or stopping at least one of the plurality of turbine generator units and adjusting, in discrete steps, a quantity of water which can flow through the dam installation, wherein a discrete step is defined by a quantity of water which can flow through a defined number of turbine generator units.

The invention concerns a method and a device for applying powder on sections of printing sheets (2). The invention includes a powder airflow (8) enclosed in a protective airflow (13) such that the powder airflow is steady and protected against the action of possible disturbances until it reaches the sections of printing sheets (2).
摘要:
The present invention relates to a device and method for dusting smooth or sheet-like products, comprising at least one duster for spraying an air/powder mixture on said products. In order to ensure efficient dusting with no dirt accumulation in the printer or the surrounding area, it is suggested that part of the powder particles be magnetized and means be provided for creating a magnetic field in the powder deposit area so that said powder particles are subjected to a force drawing them towards the product.
摘要:
Arrangement for generating electrical power from a flowing medium, wherein the arrangement includes a plurality of turbine generator units. At least some of the plurality of generator units are arranged at least one of one above another and one beside another. At least some of the plurality of generator units are connected to one another to form at least one module. At least one of the plurality of generator units includes a synchronous generator having permanent magnetic poles for excitation. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
