摘要： A system for detecting a moving hot bearing or wheel of a rail car is provided. The system includes a first comparator to receive input signals representative of radiation emitted by the moving hot rail car bearing or wheel, and to compare the input signals to a threshold value. The system further includes a counter for counting incidents of the input signals exceeding the threshold value and a second comparator to compare a number of incidents of the input signals exceeding the threshold value to a count threshold as an indication of detection of a hot rail car bearing or wheel.

摘要： Device for transmitting a temperature signal by mechanical means, which consists in the use of a thermostatic element (1) made from expandable material which, when the inner bearing heats up, pushes against a rod (2) secured to a disc-carrying piece (3) and, simultaneously, to a disc (4), which, if the temperature is sufficiently high, is displaced until it comes into contact with the outer cover (5) of the bearing mounted on the other side of the wheel, that is to say on the outside, and the higher the temperature reached by the inner bearing, the greater will be the pressure exerted by the disc (4) on the cover (5) and the more rapidly the threshold detection temperature will rise, which temperature will be picked up by the pick-up device located on the track. (FIG. 1)

摘要： A temperature warning device for monitoring the temperature of an article and for providing a dependable signal that a preselected temperature has been reached. The device includes an axially extending bore into which a heat responsive element, a driver, and a sensing indicator are arranged. The bore is normally sealed by a closure plug to prevent failure due to contaminants. Upon reaching a preselected temperature the element exerts force against the driver which in turn forcibly removes the closure plug, exposing the indicator.

摘要： 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.

摘要： 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.

摘要： An improved circuit is provided for differentiating between roller bearings and friction bearings in a railroad hot box detector system. The improved circuit integrates the waveform generated by a bearing scanner and compares that to the integral of a pre-selected portion of the waveform. By this method of comparison, irregularities in the system due to noise are obviated.
