Abstract: A vehicle wheel has a rim and spokes supporting the rim on a hub section. A clearance is formed between two mutually adjacent spokes and is covered by a flat covering element. In this case, the covering element, which is assigned to only one such clearance, is made of a fiber-reinforced synthetic material and, on an exterior side of the wheel, is glued onto the spokes which, on their mutually facing edges, have a slight step toward the interior side of the wheel, as well as onto the hub section which, in the area of this clearance on its side facing the rim, also has such a slight step. Not all clearances between two mutually adjacent spokes of the vehicle wheel are covered in such a manner.

Abstract: The invention describes a heating apparatus comprising at least one heater (9) in which one or more electric heating elements (11) are arranged, and at least one heat transmitter (1), which is connected with the at least one heater (9), comprises heat transmitter surfaces and is formed from an extruded profile (1a, 28, 28a) in which the at least one heater (9) is fitted, in which at least part of the walls (6, 22, 22a) of the extruded profile (1a), which are not in contact with a heating element (11), is provided with openings through which a gaseous or liquid medium can flow through the extruded profile (1a, 28, 28a) in transverse direction to the direction of extrusion (17).

Abstract: The invention relates to a heating device comprising heating elements that are disposed in tubes and bear against contact plates that extend out of the tubes. According to the invention, the tubes are composed of a plurality of extruded parts that are disposed transversely to the inflow direction of a fluid to be heated, and are held next to each other by a holder.
