    • 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.
    • 提供具有赤道面和最大截面宽度的充气轮胎。 轮胎包括胎面部分,胎面部分具有限定其间的胎面弧的外胎面边缘,一对侧壁部分,一对胎圈部分,每个胎圈部分具有胎圈芯,至少一个胎体帘布层,其围绕轮胎从一个胎圈部分 并且围绕胎圈芯向外缠绕,以形成一对折叠部分,每个折叠部分以折叠方式终止,以及设置在胎面部分和至少一个胎体帘布层之间的至少一个带。 当轮胎充气到其指定的膨胀压力时,胎面部分具有包括中心弧的轮廓,一对中间弧,每个中间弧在第一交点处与中心弧的相对边缘相交,并且一对外弧 每个在第二交点处与相应的中间弧相交。 从轮胎的赤道平面到至少一个第一交点测量的弧长在轮胎的胎面弧的一半的约20%至约60%之间,而从赤道平面测量的弧长 轮胎至少至少一个第二交点位于轮胎胎面弧的一半的大约40%至大约80%之间。

    • A camera assembly including first and second rotating members and a motor assembly defining a first axis and operably coupled to first rotating member to drivingly rotate first rotating member. A flexible member operably couples first and second rotating members such that rotation of first rotating member causes rotation of second rotating member. A camera is operably coupled to second rotating member such that rotation of second rotating member repositions camera. The motor assembly includes a flange having an outer circumference defining a plurality of teeth and bearing against a support surface. The outer circumference defines a radially variable distance from first axis such that rotation of outer circumference against support surface displaces first axis relative to second rotational member and thereby adjusts a tensional force in flexible member. At least one pawl mechanism is fixed relative to support surface and is engageable with outer circumference.
    • 一种包括第一和第二旋转构件的照相机组件和限定第一轴线并且可操作地联接到第一旋转构件以驱动地旋转第一旋转构件的电动机组件。 柔性构件可操作地联接第一和第二旋转构件,使得第一旋转构件的旋转引起第二旋转构件的旋转。 相机可操作地联接到第二旋转构件,使得第二旋转构件的旋转重新定位相机。 马达组件包括具有限定多个齿并抵靠支撑表面的外周的凸缘。 外圆周限定与第一轴线的径向可变距离,使得外圆周相对于支撑表面的旋转相对于第二旋转构件移位第一轴线,从而调节柔性构件中的张力。 至少一个棘爪机构相对于支撑表面固定并且可与外周接合。

    • A method and apparatus for determining the contact angle of a droplet of test liquid on a substrate surface. The apparatus includes a test article support plate, a pipette for depositing a droplet of test liquid onto a substrate surface of the test article, and a lamp for projecting an image of the deposited droplet onto a projection screen with a base line of the image positioned on a horizontal axis line of the screen. The screen further has a protractor scale calibrated to read twice the normal angular value, and a rotatable reference line which upon positioning through a contact point of the droplet with the substrate surface and an apex point of the droplet farthest removed from the substrate surface directly indicates the value of the contact angle of the on the protractor scale.
    • 一种用于确定测试液体在衬底表面上的液滴的接触角的方法和装置。 该装置包括测试物品支撑板,用于将测试液体液滴沉积到测试物品的基底表面上的移液管,以及用于将沉积的液滴的图像投射到投影屏幕上并将图像的基线定位 在屏幕的水平轴线上。 屏幕进一步具有校准为读取正常角度值两倍的量角器刻度,以及可旋转的参考线,其在通过液滴的接触点与基底表面定位并且从基底表面最远移除的液滴的顶点直接指示 量角器刻度上接触角的值。
