    摘要: A pneumatic tire having an equatorial plane and a maximum section width is provided. The tire includes a tread portion having outer tread edges that define a tread arc therebetween, a pair of sidewall portions, a pair of bead portions each of which has a bead core, at least one carcass ply extending circumferentially about the tire from one bead portion to the other and wound outwardly about the bead cores to form a pair of turn-up portions that each terminate at a turn-up, and at least one belt provided between the tread portion and the at least one carcass ply. When the tire is inflated to its specified inflated pressure, the tread portion has a profile that includes a central arc, a pair of intermediate arcs each of which intersects opposite edges of the central arc at a first intersection point, and a pair of outer arcs each of which intersects a respective intermediate arc at a second intersection point. The arc length measured from the equatorial plane of the tire to at least one of the first intersection points is between about 20% and about 60% of one half of the tread arc of the tire, while the arc length measured from the equatorial plane of the tire to at least one of the second intersection points is between about 40% and about 80% of one half of the tread arc of the tire.

    摘要: A lockable package includes an outer sleeve defined by connected first and second panels, the sleeve having at least one open end. An inner container is slidable within the sleeve, and having a first portion joined to a second portion, wherein at least one of a height and a width of the first portion is less than a corresponding height and width of the second portion. A difference between one of the height and the width of the first portion and the corresponding height and width of the second portion defines a ridge. A locking assembly is provided at the at least one open end of the sleeve and is configured to releasably engage the ridge, wherein the inner container is removable through the open end of the sleeve by disengaging the locking assembly from the ridge.

    摘要: A nitridation treated stainless steel article (such as a bipolar plate for a proton exchange membrane fuel cell) having lower interfacial contact electrical resistance and better corrosion resistance than an untreated stainless steel article is disclosed. The treated stainless steel article has a surface layer including nitrogen-modified chromium-base oxide and precipitates of chromium nitride formed during nitridation wherein oxygen is present in the surface layer at a greater concentration than nitrogen. The surface layer may further include precipitates of titanium nitride and/or aluminum oxide. The surface layer in the treated article is chemically heterogeneous surface rather than a uniform or semi-uniform surface layer exclusively rich in chromium, titanium or aluminum. The precipitates of titanium nitride and/or aluminum oxide are formed by the nitriding treatment wherein titanium and/or aluminum in the stainless steel are segregated to the surface layer in forms that exhibit a low contact resistance and good corrosion resistance.

    摘要: A method of developing a set of input forces used to analyze tire wear includes the steps of characterizing a wear course by driving a vehicle over the wear course and measuring data related to a plurality of forces experienced by the vehicle. A vehicle characterization model for a target vehicle having at least one tire is developed. The vehicle characterization model is used to calculate force data that represents the forces that would be experienced by at least one tire of the characterized vehicle if the characterized vehicle were driven over the characterized wear test course in the first vehicle configuration. The force data is then used to analyze tire wear using a computer prediction technique or by running an indoor wear test on the tire.
