Abstract: The invention provides a method for bracing functional elements, particularly PTC heating elements, in a hollow reception means, such as a profile tube. The reception means have two at least partly concave top wall areas facing one another and flat aides of the functional elements and in this way permits a bracing of the functional elements, in that side walls of the reception means, extending substantially perpendicular to the concave top wall areas, are subject to the action of a pressing pressure. In the free space areas defined by the concave top walls can be fitted ends of attachment parts, such as metal lamellas, which are clamped in the same operation, according to the invention, during the bracing of the functional elements. Thus, the invention makes it possible in a simple manner to manufacture assembled devices, particularly electric heating devices.

Abstract: Floating slag moored wave energy aggregates at sea has to be placed in a certain distance from each other not to bump into each other. At deeper depths the security distance has to be larger. This means that the cable and other costs increases without more output of energy. At sea the energy in calculated by the meter of wave front. So the advantage is to take up a little space as possible to achieve economics. If a wave energy aggregate is built with a double width to achieve the double amount of energy, this will accomplice, that the material use will be six times more than the weight for two single aggregates. To resist the strength of forces there are on this double width the use of materials is in the third power 2×2×2=8. This means an extra expense. On the power changing machines, there has to transform the energy there is nothing to save. They still have to extract the amount of energy form a double width. Therefore, it is the challenge to achieve the same energy consumption in a cheaper way.
