Abstract: A tire comprises an inner surface defining and facing an inner hollow space, an outer surface pointing away from the inner hollow space. A method of processing the tire comprises identifying the position of a first feature on the outer surface and cleaning a surface portion of the inner surface of the tire, wherein the surface portion has a first predetermined position relative to the position of the first feature on the outer surface. A separate element is attached with its attachment surface to the surface portion, wherein a ratio of a size of the surface portion over a corresponding size of the attachment surface is smaller than 10.

Abstract: A rubber article, such as a tire, bearing a digital code pattern is provided. The rubber article includes a quiet zone that surrounds the digital code pattern. The quiet zone is free of surface features in order to provide enhanced acquisition of the digital code pattern. A marking symbol is formed on the rubber article adjacent the quiet zone to provide identification of the quiet zone. A frame is optionally formed on the rubber article adjacent the quiet zone and the marking symbol to delineate the quiet zone.

Abstract: Described is in particular a method of generating a transfer pattern (110) defining a digital code pattern. According to the described method, a digital code pattern definition (104) defining a plurality of light and dark portions is received, wherein each of such portion has a size A. The transfer pattern (110) is generated by rasterizing the digital code pattern definition (104) with structure pixels, in particular by mapping the digital code pattern definition into an array of equally sized structure pixels, wherein the size A of the light and dark portions is an integer multiple of a size B of the structure pixels. The array of structure pixels comprises at least two different types of structure pixels. Each type of structure pixel defines a certain surface structure on the rubber article, the surface structure causing a certain optical reflectivity of the structure pixel. Further, at least two types of structure pixels have a different optical reflectivity.

Abstract: Described is a method of providing a rubber article (100) with a digital code pattern (102), wherein the rubber article (100) comprises a cured polymer material (104), the method comprising: Generating, e.g. by means of electromagnetic radiation (110), a digital code pattern (102) in the cured polymer material of the rubber article, the digital code pattern (102) comprising a first surface portion (106) and a second surface portion (108) having different optical reflectivity. Generating the digital code pattern (102) may include generating protrusions (114) or holes (126) in the second surface portions (108). The digital code pattern (102) may identify the rubber article (100) e.g. within a batch of rubber articles. Described is also a rubber article (100) comprising a digital code pattern (102), a rubber article marking device and a computer program product for controlling a rubber article marking device.

Abstract: The present application refers to a process for preparing 6,10- and 6,9-dimethyl-5,10-undecadienyl-2-ones by telomerizing isoprene with alkyl acetoacetates in the presence of a catalyst system containing a transition metal compound catalyst and a phosphorus- or arsenic-containing compound cocatalyst, wherein the process is performed in the presence of a protic additive of the general formula in which: R1, R2, R3 represent an alkyl group with 1 to 9 carbon atoms, branched or unbranched, a cycloalkyl group with 6 to 8 carbon atoms, an aryl group, in particular phenyl, or an arylalkyl group, X(−) represents an inorganic or organic anion, y is 1 or 2, and the &bgr;-ketoester so obtained is saponified and decarboxylated in a manner known per se.
