摘要： Method and apparatus for determining dynamic lateral and vertical wheel-rail forces. Axle bending sensors and axle load cells provide signals to a computer programmed to calculate lateral and vertical wheel-rail forces. These forces are used as the basis for comparing the effects of a variety of car truck design criteria and track conditions. Comparison of forces developed by the same equipment on different runs over the same trackage discloses track condition changes between runs.

摘要： A rotating warning light intended to be mounted on the roof of a vehicle which includes four rotating lightbulbs facing outwardly in four different directions. Three of the lightbulbs have colored lenses, e. g., red or blue, and the remaining lightbulb has a clear lens defining a spotlight under certain conditions. The device includes structure for (1) remotely moving the spotlight about a horizontal axis so the beam therefrom may be lowered or raised; (2) continuous operation of the four lightbulbs simultaneously while they rotate, thus providing a highly conspicuous wig-wag effect; (3) selectively reversing the direction of rotation of the platform supporting the four lightbulbs, thus facilitating optimum maneuverability of the spotlight; (4) continuous operation of the spotlight while simultaneously flashing the colored lights, thus providing a warning signal while utilizing the spotlight feature; (5) continuous operation of the spotlight while the colored lights are off, thus providing for an improved power-assist highly maneuverable spotlight having unobstructed 360* utilization.
摘要翻译：一种旨在安装在车辆屋顶上的旋转警告灯，其包括在四个不同方向上面向外的四个旋转灯泡。三个灯泡有彩色镜片，例如红色或蓝色，剩余的灯泡具有在特定条件下限定聚光灯的透明透镜。该装置包括用于（1）围绕水平轴线远程移动聚光灯的结构，使得其中的光束可以被降低或升高; （2）四个灯泡在旋转时同时连续运转，提供高度显眼的假发效果; （3）选择性地反转支撑四个灯泡的平台的旋转方向，从而促进聚光灯的最佳机动性; （4）聚光灯连续工作同时闪烁彩色灯光，从而在利用聚光灯特征的同时提供警告信号; （5）彩色灯关闭时聚光灯的连续运行，从而提供无阻碍360度利用的改进的助力高度机动的聚光灯。
