Abstract: The invention relates to a system for inductive power transfer to vehicles driving or standing on a surface of a route, in particular to road automobiles, wherein the system includes a primary winding structure for generating an alternating electromagnetic field, wherein a field volume (FV) is assigned to the primary winding structure, wherein the system includes at least a part of a first heating system, wherein elements of the first heating system which are arranged within the field volume (FV) are non-metallic elements. Further, the invention relates to a pavement slab assembly and a method of operating a system for inductive power transfer.

Abstract: A pavement slab assembly for a route for vehicles driving or standing on a surface of the route. The pavement slab assembly consists at least partially of pavement material and has a cable bearing element. Electric line or lines extend(s) along or under the surface of the pavement slab assembly. The cable bearing element is embedded in the pavement material of the pavement slab assembly and is arranged within the pavement slab assembly such that the cable bearing element is enclosed by the pavement material. The invention also relates to a method of building a pavement slab assembly, a route for vehicles, and a method for building a route for vehicles.

Abstract: A device for regulating flow comprises a main valve operating under differential pressure wherein the main valve has a main flow inlet and a main flow outlet. The main flow inlet is equipped with a valve seat over which a main shutter is adjusted in a perpendicular direction to its shuttering plane. The main shutter has a hole on its locking face communicating with a pressure chamber disposed above the main shutter. A secondary control valve regulates small flows through the hole so as to create greater or less pressure within the pressure chamber to close or open the main shutter.
