摘要： A sheave basket weighing system is disclosed for use in a material handling apparatus. The weighing system comprises a sheave basket with three bending beam load cells fixed on the sheave basket to provide a three-point support system. One of the load cells is preferably positioned intermediate to the other two load cells. A ladle hanger assembly is supported on top of the load cells. The weighing system provides a stable three-point support which can withstand side loading without the necessity of movable load cells and without the use of check rods, which could result in weighing inaccuracies.

摘要： A light is dimmed by pulsing it at a selected duty cycle. By pulsing, the light can be dimmed without being turned off completely which reduces wear on the filament. The circuit is designed for flashing a pair of ditch lights on a railroad locomotive. The lights are alternately illuminated at full voltage and dimmed by pulsing. The flashing sequence can be activated when the locomotive is travelling below a selected speed or when the horn is sounded. The duration of the flashing sequence is controlled by a timer. The pulsing circuit can be used to effectively reduce a voltage without voltage dropping resistors.

摘要： A visual warning system for a locomotive is disclosed which includes a signal unit mounted on the locomotive and connected by sensing means to an audible warning device on the locomotive, such as a horn. The visual warning signal unit is thus actuated whenever the horn is sounded. The signal unit comprises a stroboscopic-type lamp assembly and flashing circuitry with a coating of phosphorescent material surrounding the lamp to extend the perceived duration of each flash of the lamp. The system may also include a delay for maintaining the flashing of the visual warning signal unit after the horn has been deactuated.

摘要： Heaters are used to simulate wheel bearings at specified temperatures. Two heaters are mounted on each side of a railroad test car. The heaters are mounted on the sprung carriage of the car to reduce vibration of the hardware and avoid interfering with wheel trucks on the car. Ambient temperature sensors are similarly mounted. Wire brushes are mounted below the heaters and sensors to activate magnetic wheel flange sensors. The heaters are controlled by a system which is integrated with a hot wheel simulator system.

摘要： A simulator is provided for verifying the proper operation of railroad rolling stock hot wheel detectors. The simulator includes heaters mounted on trucks of a railroad car, between the wheels and within the profile of the thickness of the wheels. Shock mounts, spring mounts and safety cables are used. An electromagnet is mounted on the heater to trip a sensor to activate the detector and a sensor on the car is used to determine the ambient temperature. Each heater includes a heater temperature sensor and is maintained at a constant temperature above ambient to approximate the thermal radiation of a hot wheel. Each heater is adjusted to direct heat horizontally outwardly from the truck to permit a hot wheel detector adjacent to and outside of the rail to detect a hot wheel. The car has two trucks with one heater on each side of each truck. One heater on each side simulates a temperature approximately equal to a hot wheel. The other heater on each side simulates a lower temperature and should not be detected as a hot wheel. The simulator can be integrated with a hot bearing simulator system.
摘要翻译：提供了一种模拟器，用于验证铁路车辆热轮检测器的正确操作。模拟器包括安装在铁路车辆的卡车上的加热器，在车轮之间和车轮厚度的轮廓内。使用冲击安装，弹簧座和安全电缆。电磁铁安装在加热器上以使传感器跳闸以启动检测器，并且使用汽车上的传感器来确定环境温度。每个加热器包括加热器温度传感器，并且保持在高于环境温度的恒定温度以接近热轮的热辐射。每个加热器被调节以将热量从卡车水平向外引导，以便允许在轨道附近和外部的热轮检测器检测热轮。这辆车有两辆卡车，每辆卡车的两边都有一个加热器。每侧一个加热器模拟大致等于热轮的温度。每侧的另一个加热器模拟较低的温度，不应被检测为热轮。模拟器可以与热轴承模拟器系统集成。
