A system and method for transmitting user credentials to another device. A visualization platform may register feature extensions and receive requests to create objects. The degree of perforation of the through flow elements and the distance between these elements are preferably adapted to one another in such a way that a reflection free condition for combustion pulsation frequencies which may be expected is present at the exit from the burner into the combustion chamber. Note that a first region around the positive feature defines a first plane, and the positive feature protrudes above the first plane. The present invention provides a graphical user interface for monitoring and managing the components of the resource consumption and resource infrastructure of at least one building. To enable the carding nip to be adapted or kept constant, adjusting elements of the machine element and adjusting elements of the bearings each have inclined bearing surfaces, and the machine element, in the event of undergoing thermally induced expansion in its longitudinal direction, is so displaceable along the inclined surfaces that the radial spacing remains the same.
