Abstract: This invention relates to apparatus for the detection of accustic impact frequencies, characteristic of bearing assembly failure during operation, which modulate an acoustic carrier frequency band. This apparatus allows for on-site or field application with high-level of ambient noise such as are present in railroad yards. This apparatus allows for early detection of such failures, so that a repair may be made before damaging heat build-up or catastrophic bearing failure occurs. Additionally, with sufficient early warning in railroad applications, a train may continue running to a railyard for convenient shop repair rather than expensive field repair.

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.

Abstract: An improved heat sensing tip for a temperature sensing device is provided. The tip comprises an elongated shell of heat conductive material. A temperature probe is positioned for movement within the shell toward and away from an opening in the shell. A cap of heat conductive material is positioned at the front of the probe. A spring urges the cap in contact with the shell for heat conductivity between the two when the device is not in operation. When the device is in operation, the spring bias is overcome thereby providing an insulating air gap between the shell and the tip.

Abstract: A system to permit the visual observation of objects moving along a fixed path. The object is viewed through a television camera which images the object through an optic axis bending element. The bending element is angularly rotated in a sawtooth manner with the slope of the sawtooth determined by the speed at which the object moves along the path so as to track the object to immobilize the scene viewed by the mirror.

Abstract: An improved method and circuit is provided for processing waveforms from a railway car heat signal to eliminate spurious signals and to differentiate between roller bearings and friction bearings in a railroad hot box detector system. The waveforms generated by passing bearings are discretely sampled and spurious signals are eliminated by considering only those signals that fall within the crossing points of a threshold value. Discrimination between roller bearings and friction bearings is obtained by determining the ratio of the sum of the discrete values of the amplitude of the waveform within a first set of samples between the crossing points to the sum of the discrete values of the amplitude of the waveform within a second set of samples between the crossing points.
