Publication number: 20100154948Abstract: A tire has an axis of rotation. The tire includes two sidewalls extending radially outward and a tread disposed radially outward of the two sidewalls and interconnecting the two sidewalls. The tread includes a main portion comprising a first compound and a reinforcing structure comprising a second compound having reinforcing short fibers oriented between ?20 degrees to +20 degrees to a circumferential direction of the tread. The main portion of the tread includes at least one circumferential groove separating circumferential ribs. Each circumferential groove has two sides and a base therebetween. The reinforcing structure includes a layer of the second compound secured to the sides of each circumferential groove.Type: ApplicationFiled: December 22, 2008Publication date: June 24, 2010Applicant: Goodyear Tire & Rubber CompanyInventors: Johan Peter Dahlberg, Stephane Jose Geelen, Annette Lechtenboehmer, Filomeno Gennaro Corvasce, Matthieu Pingenat, Pierre Bernard Raoul Brochet, Anne Therese Peronnet-Paquin, Jacek Wojcik, Jean Luc Dheur, Isabelle Lea Louise Marie Lambert

Patent number: 7278455Abstract: A pneumatic tire is capable of operation during underinflated condition and the construction of sidewalls are configured to compensate for negative cambers acting upon the tire. The inboard side of the tire is softened in comparison to the outboard side of the tire. This is achieved by either forming an asymmetrical tire in either the tire profile or the internal construction.Type: GrantFiled: December 20, 2004Date of Patent: October 9, 2007Assignee: The Goodyear Tire & Rubber CompanyInventors: Marc Hedo, Johan Peter Dahlberg, Walter Dale Allen, Laurent Luigi Domenico Colantonio, Filomeno Gennaro Corvasce

Publication number: 20070095036Abstract: This disclosure describes an apparatus which will enable high temperature filtration of particulate laden gases through a composite filter that consists of a layer of in-expensive granular filter media that is supported on a high temperature porous media. It also describes a method for regenerating the composite filter media when the pressure drop across said media becomes too high. The purpose of such a high temperature composite filter is to inexpensively facilitate the filtration of high temperature gases bearing sticky particulate in a low pressure drop continuous and reliable manner. Particulate from hot gases are captured by the granular filter media. When the pressure drop across a filter element becomes too high, a reverse flow of gas through the high temperature porous media causes the granular media to slide down the inclined porous media.Type: ApplicationFiled: November 1, 2005Publication date: May 3, 2007Inventor: Peter Dahlberg

Patent number: 7093633Abstract: A self-supporting pneumatic tire is molded in such a manner that ride comfort is improved, durability is increased, and a greater run-flat capability can be achieved. The self-supporting run-flat tire is molded such that the molded bead base width is equal or less than the rim width of the intended rim upon which the tire is to be mounted. By molding the tire with a bead width less than or equal to the rim width, the sidewall inserts are not subjected to additional stress during and after inflation of the tire and the strain energy is more evenly distributed through the sidewall pillar construction.Type: GrantFiled: October 29, 2003Date of Patent: August 22, 2006Assignee: The Goodyear Tire & Rubber CompanyInventors: Johan Peter Dahlberg, Laurent Luigi Domenico Colantonio, Walter Dale Allen

Patent number: 6564839Abstract: The present invention relates to a radial ply tire (230) with a tread (232) subdivided transversely into a central portion (250) having central ribs (260a,260b), shoulder portions (254a, 254b) having shoulder ribs (270a,270b) and intermediate portions (252a, 252b) having intermediate ribs between the central portion and the shoulder portions. The tread has intermediate grooves (262a,262b) between the central ribs and the intermediate ribs (266a,266b) and shoulder decoupling grooves (264a,264b) between the intermediate ribs and the shoulder ribs (270a,270b). The shoulder decoupling grooves having a depth (D1) being less than the intermediate decoupling grooves whereby the footprint width of the tread surface can expand from first width (NLFPW) under normal load to a second width (HLFPW) under heavy load.Type: GrantFiled: November 1, 2000Date of Patent: May 20, 2003Assignee: The Goodyear Tire & Rubber CompanyInventors: Philippe Marie Manne, Laurent Colantonio, Johan Peter Dahlberg, Frank Philpott

Patent number: 5539732Abstract: The invention relates to an arrangement adapted for use in switching equipment which is included in a telecommunications system, wherein the switching equipment includes, among other things, a number of incoming connections (4) that can be coupled via first coupling units (3); a number of outgoing connections (4a) that can be connected via second coupling units (3a);wherein the switching equipment (2) cooperates with or includes requisite control means (11) and coupling means (10) for connecting an incoming connection (4) and/or a part-data flow occurring on such a connection with an indicated outgoing connection (4a), and/or data part-flow that can be transmitted on such a connection;wherein a number of category allocating devices (31) belonging to respective connections and pre-configured normally by a processor associated with the control means (11) are adapted to allocate to each time slot belonging to the time-divided data flow a predetermined category membership such as a "control"-time slot, a CTS-signType: GrantFiled: March 16, 1994Date of Patent: July 23, 1996Assignee: Telefonaktiebolaget L M EricssonInventors: Lars Schyman, Anders Bjenne, Peter Dahlberg

Patent number: 5495477Abstract: A signal transmission system includes one or more signal transmitting units, one or more signal receiving units and a medium adapted for the transmission of selected signals. A transmitted signal carries a number of signal elements which have been allocated to the same or different categories. A number of signal elements that have been allocated to the same category can be coordinated in a receiving unit to form predetermined information. The system includes a unit to increase the number of signal elements that have been allocated to one category (CTS) at the cost of the number of signal elements that have been allocated to another category (DTS) and/or a third category, and so on, or alternatively to carry out one or more selected functions within equipment connected to the receiving unit.Type: GrantFiled: March 16, 1994Date of Patent: February 27, 1996Assignee: Telefonaktiebolaget L M EricssonInventors: Lars Schyman, Anders Bjenne, Peter Dahlberg

Patent number: 4332492Abstract: In a printer comprising a printing head, which is supported by a carriage, the carriage position along a record carrier is sensed at two occasions. A cooperating micro processor calculates an actual carriage speed on the basis of the position values which are obtained. The actual carriage speed and an optimal carriage speed, which is stored, are compared and on the basis of this comparison a compensation factor is calculated for a reference signal (Ref) which determines the carriage speed. This compensation factor is checked at each carriage movement by measuring the carriage speed. Accordingly a permanently optimal carriage speed is secured and the need of an accurate trimming of the carriage speed is eliminated during manufacture as well as at later service periods.Type: GrantFiled: September 19, 1979Date of Patent: June 1, 1982Assignee: U.S. Philips CorporationInventors: Rolf A.
