Abstract: A pneumatic tire is provided that has a way to provide information. The pneumatic tire has at least at one predetermined location a rubber mixture that is permeated with magnetizable particles that are magnetized in a number of first zones and differently or not at all in a number of second zones. The tire can be used in a slip regulation system, and apparatus for producing such a tire are also provided.

Abstract: A vehicle wheel is provided with a pneumatic tire and has a way to provide information. The pneumatic tire has at least at one predetermined location a rubber mixture that is permeated with magnetizable particles. An annular band of this rubber mixture contains the magnetizable particles anisotropically aligned in a peripheral direction of the tire. The tire can be used in a slip regulation system.

Abstract: An organic, high-molecular weight polyester containing substantially chain members of the formula--O--X--O--Y--wherein X is at least one member of the group consisting of ##STR1## and Y has the formula ##STR2## having an inherent viscosity of at least 1.0 dl/g, preferably at least 1.2, dl/g measured at 30.degree. C. in a solution of 0.5 g of the polyester in 100 ml of a mixture of 60% by weight of phenol and 40% by weight of 1,1,2,2-tetrachloroethane and whose films cast from a chlorinated organic solution have an elongation at break of at least 10%, preferably at least 20%, measured according to ASTM D-882-75 b with the proviso that if the inherent viscosity is between 1.0 dl/g and 1.5 dl/g, Y is a mixture of 70 to 30% of terephthalic acid and 30 to 70% of isophthalic acid having excellent properties for electrical insulation as well as other fields.

Abstract: An organic, high-molecular weight polyester containing substantially chain members of the formula ##STR1## wherein X is at least one member selected from the group consisting of ##STR2## having an inherent viscosity of at least 1.0 dl/g, preferably at least 1.2 dl/g measured at 30.degree. C. in a solution of 0.5 g of the polyester in 100 ml of a mixture of 60% by weight of phenol and 40% by weight of 1,1,2,2-tetrachloroethane and whose films cast from a solution in a chlorinated organic solvent have an elongation at break of more than about 20%, preferably at least 40% measured according to ASTM D 882-75 b having excellent properties for electrical insulation as well as other fields.
