DISTRIBUTOR DEVICE, SYSTEM, AND METHOD FOR SEALING AND USING A METERING UNIT
The invention relates to a distributor device (1) for generating an aerosol (8) comprising both gas and sealant, wherein the distributor device has at least one gas connector (2) for connection to at least one compressed-air source (11), at least one sealant connector (3) for connection to at least one sealant container (12), and one or more than one connecting element (4) for connection to a pneumatic vehicle tire (16), characterized in that the distributor device has a metering unit (5) for metering the sealant quantity fed to the distributor device. The invention also relates to a system for sealing and inflating pneumatic vehicle tires, and to a method for sealing pneumatic vehicle tires or inflatable technical articles, and to the use of a dosing unit for generating an aerosol.
The invention relates to a polymer product, preferably a vehicle tire (1) with sidewalls (2), comprising a photorealistic representation (3) on the outer surface of the polymer product (2), wherein the photorealistic representation consists of the combination of a structure with a relief (5) of the representation, wherein the structure has elevations (7) and depressions (6) and wherein the relief (5) is a depth chart of the representation that is preferably produced on the basis of grayscale values of a photo and has up to 256 gradations of depth in such a way that the relief (5) fills the depressions (6) of the structure to different heights according to the grayscale value.

For generation of a photorealistic representation (3), the structure is an undirected texture (4) composed of elevations (7) and depressions (6).
The invention is directed to a vehicle pneumatic tire wherein strengthening plies are provided with steel cords running parallel to one another. The belt plies can be used, as isolated electrically conductive plates, for supplying electricity to electrical consumers such as sensors and actuators installed in the tire. Adjacent belt plies can be connected by puncture sensors to be able to identify damage to the belt caused by metallic parts penetrating from the outside, such as nails, on the basis of a change in the electrical resistance.
