Patent number: 10894452Abstract: A mounting member for an air maintenance tire is provided. The tire includes a sidewall that is formed with a groove for receiving an air tube and a recess for receiving at least one pneumatic connector that is in fluid communication with the air tube. The mounting member includes a plurality of layers, in which the layers are in stacked alignment with one another. The plurality of layers includes at least an axially outward layer and an axially inward layer. The mounting member is received in the recess and secured to the tire sidewall, thereby securing the position of the at least one pneumatic connector. A method of forming a mounting member for an air maintenance tire is also provided.Type: GrantFiled: November 14, 2017Date of Patent: January 19, 2021Assignee: The Goodyear Tire & Rubber CompanyInventors: Benjamin Isaiah Garn, Dinesh Chandra, Sagar Dilip Bafana, Cheng-Hsiung Lin, Daniel Vojtko

Publication number: 20200009927Abstract: A self-inflating tire assembly includes an air tube mounted within a tire sidewall groove. The air tube is in contacting engagement with opposite angled groove surfaces surrounding the air tube. A segment of the air tube is flattened from an expanded diameter to a flat diameter by bending and compression of the groove in a rolling tire footprint to force air evacuated from the flattened segment along a tube air passageway. The sidewall groove extends into an annular, axially extending, sidewall surface such as an axially oriented surface of a tire chafer protrusion located in non-contacting relationship with the rim. The air tube is extruded from a rubber composition, the rubber composition comprising: a diene based rubber; from 0.Type: ApplicationFiled: September 4, 2019Publication date: January 9, 2020Inventors: Andreas FRANTZEN, Carolin Anna WELTER, Anne Therese PERONNET-PAQUIN, Mingliang DU, Stephan RODEWALD, Betul BUEHLER, Benjamin Isaiah GARN, Daniel VOJTKO, Jungmee KANG, Dinesh CHANDRA

Patent number: 10449813Abstract: A self-inflating tire assembly includes an air tube mounted within a tire sidewall or chafer groove. The air tube is in contacting engagement with opposite angled groove surfaces surrounding the air tube. A segment of the air tube is flattened from an expanded diameter to a flat diameter by bending and compression of the groove in a rolling tire footprint to force air evacuated from the flattened segment along a tube air passageway. A coverstrip overlays and seals the groove and provides an abrasion resistant surface on the exterior of the tire. The coverstrip is made from a vulcanizable rubber composition comprising from 50 to 80 phr of a polybutadiene, from 50 to 20 phr of natural rubber, and from 0.1 to 5 phr of a vulcanization modifier.Type: GrantFiled: January 26, 2017Date of Patent: October 22, 2019Assignee: The Goodyear Tire & Rubber CompanyInventors: Jungmee Kang, Byoung Jo Lee, Daniel Vojtko, Dinesh Chandra, Betul Buehler, Benjamin Isaiah Garn

Patent number: 9718732Abstract: A cementitious composition including at least one cementitious material and at least one crack reducing admixture including: (i) from 0 to about 5 weight percent of at least one alcohol, based on the total weight of the admixture excluding water; and (ii) a compound having the chemical structure of formula (III): wherein: v is an integer from 0 to 50 and w is an integer from 0 to 50, with the proviso that the sum of v and w is at least 1 but not greater than 50. Also, methods of making the cementitious composition, reducing or eliminating the formation of cracks in a cementitious composition as the cementitious composition cures, and limiting the size of cracks which form in a cementitious composition as the cementitious composition cures using an admixture for cementitious compositions as described herein.Type: GrantFiled: November 21, 2014Date of Patent: August 1, 2017Assignee: Construction Research & Technology GmbHInventors: Steve Schaef, Emmanuel Attiogbe, Charles Kerobo, Stefan Muessig, Daniel Vojtko
