    Abstract: An alarm circuit monitor for use with railroad car hot box detection equipment is provided. The monitor, which is connected to hot box detectors adapted to generate signals responsive to the temperature of the bearings on both sides of each axle of a railroad car under consideration, includes a first circuit adapted to trigger an alarm in the event the signal responsive to the operating temperature of either bearing exceeds a threshold level for normally low running temperature bearings and a cancellation circuit to prevent the first circuit from triggering the alarm if the operating temperature of the other bearing also exceeds the low level threshold. A second circuit independent of the first circuit is also connected to the hot box detectors to trigger the alarm in the event the hot box detector signal exceeds a threshold level for normally high running temperature bearings.

    Abstract: A hot box detector system is provided in which an infra-red scanner (16) is arranged to scan the wheel bearings of railway rolling stock passing over a section of track (10) and to generate signals which are processed to determine the temperature of the bearing, the nature of the bearing, and, for signals derived from bearings within a closed housing (24, 26), to determine if the scanned surface of the housing is an inner sidewall (32, 34) or an outer sidewall (36, 38) of the housing (24, 26) relative to the bogie (22) to which the bearing belongs. Train speed is also determined from wheel detectors 12, 14. The signals are then normalised to account for differences in the heat dissipating characteristics of the inner outer sidewalls, and the air stream cooling resulting from the movement of the train before being analyzed to determined whether or not the bearing is overheated.

    Abstract: 820,919. Hot-axle detectors. SERVO CORPORATION OF AMERICA. Nov. 6, 1957 [Nov. 6, 1956; Aug. 6, 1957], No. 34657/57. Class 40 (3). A detector for the hot axle bearings of rail wagons comprises a heat-responsive control element, e.g. an infra-red detecting thermistor, mounted alongside the track, and an inclined optical system with its axis preferably at 20- 50 degrees to the horizontal and in a plane parallel to the rail track. There may be two such systems pointing in opposite directions with trip means operating shutters appropriate to the direction of movement of the wagons. There may be two heat detectors with separate optical systems, or a single detector with a mirror operated by the trip means, to incline in the receiving direction and reflecting the heat on to the detector. Alternatively, the shutters are controlled and held by the trip means. The journal box 18 is progressively scanned by the detector 10 as the rail car 19 moves along the track 13. The wheel trip 34 maybe a magnetic circuit closed by the wheel flange 25 and in a circuit containing a single-stability multivibrator or a time-delay grop-out relay giving a gate interval for the detector of about 50 milliseconds, sufficient even for slow trains of 5 m.p.h. A storage device in conjunction with the wheel trip operates the shutter of the detector for a sufficient period when the train is slow. Two wheel trips in series with a flip-flop circuit give a square gating pulse sufficient for full exposure of the hot box (Fig. 6, not shown). A single detector cell 14 (Fig. 8) serves duplicate optical systems 44, 44 , with shutters 51, 52 operated by solenoids 53, 54. The sequence in which the wheel trips 34, 56 are operated affects the directionally responsive switch 74 which determines the actuation of the solenoid and storage means 38, 38 , supplies a steady signal to relay means 76 to control the trip pulses, and turns on the recorder, alarm and telemetering devices 30, 31, 32.

    Abstract: IMPROVED RAILROAD HOT BOX DETECTOR A hot box detector system is provided wherein heat signals from bearings within a housing are analyzed to determine if the scanned surface of the housing is an inner sidewall surface or an outer sidewall surface. The signals are normalized to account for differences in the heat dissipating characteristics of the inner and outer sidewalls and air stream cooling resulting from the trains movement.
