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: 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.
