Patent number: 5474645Abstract: A product and process for imparting decorative appliques to the sidewalls of tires during the curing operation are presented. A spool of applique composite material is maintained for feeding into a tire mold or onto a transfer device, thereby defining a ring for vulcanization to a tire. The applique consists of a laminate received upon a carrier, the laminate having a first barrier layer and a congruent second decorative layer. The laminate is received by a tire sidewall between two grooves which serve to isolate the decorative layer from the tire itself.Type: GrantFiled: January 24, 1990Date of Patent: December 12, 1995Assignee: Bridgeston/Firetone, Inc.Inventors: Georg G. A. Bohm, Arthur E. Oberster

The applique consists of a laminate received upon a carrier, the laminate having a first barrier layer and a congruent second decorative layer. The laminate is received by a tire sidewall between two grooves which serve to isolate the decorative layer from the tire itself. In another embodiment a laminate of white and barrier rubber stock is formed and then configured into a cylinder. A plurality of bands are cut from the cylinder then transferred to a fixture by reorienting the bands to conform to the angle of the sidewall of the tire at the point with which the band is to be adhered.Type: GrantFiled: March 21, 1994Date of Patent: May 9, 1995Assignee: Bridgestone CorporationInventors: Georg G. A. Bohm, Arthur E. Oberster, James H. C. Yang

Patent number: 5300164Abstract: According to the present invention, a pneumatic tire includes a cured tread area, an outer sidewall area connected to the tread area, and an outer bead connected to the sidewall area at an end thereof and defining an opening for receiving a wheel. The tire also includes a pre-cured, elastomeric, decorative applique and an applique-contacting adhesive layer positioned between the sidewall and the applique. A method according to the present invention, of providing a cured pneumatic tire with a decorative outer sidewall, includes the step of bonding to the outer sidewall of the cured pneumatic tire a cured, elastomeric, decorative applique with an adhesive layer.Type: GrantFiled: February 7, 1992Date of Patent: April 5, 1994Assignee: Bridgestone CorporationInventors: Mario N. DeTrano, James H. C. Yang, George G. A. Bohm, Arthur E. Oberster, Russell W. Koch

Patent number: 5202363Abstract: A reinforcing agent for vulcanizable rubber compounds comprises an anhydrous metal salt of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid having a crystalline structure consisting essentially of plates and fibers. Vulcanizable rubber compounds containing such reinforcing agents have improved physical properties over rubber compounds containing conventional metal carboxylic acid salts. Methods for the preparation of such anhydrous metal salts and methods for the reinforcement of vulcanizable rubber compounds therewith are also provided.Type: GrantFiled: April 16, 1990Date of Patent: April 13, 1993Assignees: Bridgestone/Firestone, Inc., Bridgestone CorporationInventors: Arthur E. Oberster, Takatsugu Hashimoto

Patent number: 5096943Abstract: A method for incorporating metal salts of .alpha.,.beta.-ethylenically unsaturated carboxylic acids into polymers and improving the cured physical properties of vulcanizable rubber compositions based on such polymers. The method includes the steps of preparing a polymer cement in a suitable organic solvent, forming a suspension of the metal salt of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid in a suitable aliphatic hydrocarbon solvent miscible with the organic solvent, mixing the polymer cement and the suspension together and thereafter removing the solvents to provide the metal salt uniformly dispersed within the polymer.Type: GrantFiled: April 16, 1990Date of Patent: March 17, 1992Assignees: Bridgestone/Firestone, Inc., Bridgestone CorporationInventors: Takatsugu Hashimoto, David M. Roggeman, Arthur E. Oberster, Jung W. Kang

Patent number: 4987192Abstract: Colored tire stocks having improved abrasion resistance, color and color stability as compared to conventional colored tire stocks such as white sidewall stocks are provided. The colored tire stocks of the invention comprise crosslinked colored rubber compositions containing from 10 to 90% of ionic crosslinks and from 90 to 10% of free radical induced covalent crosslinks. These colored tire stocks may be utilized as functional tire stocks such as colored sidewall stocks (e.g. white sidewalls) or as decorative tire stocks such as raised colored letters (e.g. raised white letters) which identify the tire manufacturer.Type: GrantFiled: May 19, 1989Date of Patent: January 22, 1991Inventors: Arthur E. Oberster, Charles M. Roland, Georg G. A. Bohm
