    • Method and apparatus for evaluating temperature indicating signals from a railway hot box detector and producing an alarm signal therefrom. The signals are differentially evaluated and are compared to appropriate reference signals to detect overheated solid or roller bearings. False alarm signals produced from the differential evaluation because of the difficulty in distinguishing the temperatures of normally operating roller bearings from those of overheated solid bearings are detected and cancelled. False alarm signals caused by noise and by time displacement between temperature indicating signals are cancelled by checking the duration of all alarm signals and passing only those that have long enough durations not to have been produced by noise or by differential evaluation of time displaced temperature indicating signals. The alarm system is advantageously connected in circuit with a chart recorder to produce a permanent record of hot boxes.
    • 用于评估来自铁路热箱检测器的温度指示信号并从其产生报警信号的方法和装置。 信号进行差分评估,并与适当的参考信号进行比较,以检测过热的固体或滚子轴承。 由于难以区分正常操作的滚柱轴承的温度与过热的实心轴承的温度差异性评估产生的误报警信号被检测和取消。 通过检查所有报警信号的持续时间并仅通过具有足够长的持续时间不被噪声产生的时间或者通过时间偏移温度指示信号的差分评估来消除由温度指示信号引起的噪声和时间位移引起的误报警信号 。 报警系统有利地与图表记录器连接在一起,以产生热箱的永久记录。

    • Apparatus and method for automatically servicing the journal boxes of railroad cars moving along a track at unknown speeds. A journal box servicing device, for example, a journal box lid lifter or a journal box oiler is positioned alongside the track. Sensors detect the presence of each journal box at a first point and at a second point on the track as the car travels toward the device. The sensors are used to provide information functional of the speed of the car. This information is utilized with a reference signal which represents the response time of the journal box servicing device to transmit an actuating signal to the servicing device at the proper time in advance of the arrival of the journal box at the servicing device so that the operation of the device is substantially synchronized with the arrival of the journal box at the device. Another reference signal is also supplied to the system that prevents giving of the actuating signal to the servicing device in the event that the travel time of the car and the journal box between the first point and the second point exceeds a predetermined maximum.
    • 用于以未知速度沿轨道移动的铁路车辆的日志箱的自动维修的装置和方法。 一个日志箱维修装置,例如一个日志箱盖提升器或一个杂志箱加油器位于轨道旁边。 当汽车向设备行驶时,传感器在轨道的第一点和第二点处检测每个日志箱的存在。 传感器用于提供汽车速度的功能。 该信息与参考信号一起使用,该参考信号表示在记录箱到达维修装置之前的适当时间的日志箱服务设备响应时间以将执行信号发送到维修设备的操作, 该装置基本上与装置上的日志箱的到达同步。 在第一点和第二点之间的轿厢和日志箱的行进时间超过预定的最大值的情况下,另一个参考信号也被提供给系统,该系统防止向维修装置发出致动信号。
