    • Example dock levelers installed at a vehicle loading dock include pivotal or otherwise vertically adjustable deck plates with special coatings on the deck's upper surface. In some examples, the coating improves traction and addresses various thermal issues, such as condensation and thermal strain between a polymeric coating and a steel deck plate. In some examples, when indoor and outdoor air create a temperature differential across opposite faces of the deck, the coating is designed such that a median temperature of the temperature differential occurs near an interface where the coating bonds to the steel plate's upper surface. In some examples, the coating includes particles of different sizes and colors embedded within and covered by a polymeric base material. As traffic abrades the coating, the different colored particles become exposed at different levels of wear, thereby providing a visual signal indicating when the coating needs to be touched up or replaced.
    • 安装在车辆装载码头上的示例码头调平器包括在甲板上表面上具有特殊涂层的枢轴或其他可垂直调节的甲板板。 在一些实例中,涂层改善牵引力并解决各种热问题,例如聚合物涂层和钢甲板之间的冷凝和热应变。 在一些示例中,当室内和室外空气在甲板的相对面上产生温差时,涂层被设计成使得温度差的中间温度发生在涂层粘结到钢板的上表面的界面附近。 在一些实例中,涂层包括嵌入聚合物基材并由聚合物基材覆盖的不同尺寸和颜色的颗粒。 随着交通磨损涂层,不同的着色颗粒以不同的磨损水平暴露,从而提供指示何时需要接触或更换涂层的视觉信号。

    • 23,430. Maxey, R. E. L. Dec. 14, 1904, [date applied for under Patents Act, 1901]. Sleepers ; sound and vibration, preventing. - A railway cross-tie consists of a pair of rail-supporting members attached to a transverse member to which they are connected by stay pieces. The railsupporting members consist of a pair of channel. bars having heavy upper flanges 13, 14, Fig. 1, and connected by rivets 12, Fig. 2, through their webs 10, 11. The rivets also secure to them the bent ends 24, 25, and 29, 30 of the webs of the transverse members, the flanges of which are cut away as shown. The webs of the transverse members are similarly riveted together and the diagonal brace pieces 31, 32 are secured as shown by the same rivets. Spaced guard plates 17, 18 are riveted to the upper flanges for taking the lower flanges of the rail, which is secured by elongated washers 34 and bolts 19, Fig. 5, the nuts 20 on which are secured by keys 35. Pads of flexible material, such as leather, are placed between the rail and the supporting member. In a modification, the transverse member is in one piece and the longtiudinal rail supports divided and secured by the bent ends of the webs.
