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 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.

摘要： 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.

摘要： A railroad car hot box detector system is provided which includes a variable circuit means for processing the heat signal generated by an infra-red detector viewing a sensing zone along a section of track. The system includes a conditioning circuit which determines one or more conditions of the train (such as the wheel speed or temperature of the car bottom) and uses that information to vary the processing circuit to enable the heat signal to be processed optimally for the detected condition.

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.

摘要： A circuit for producing an output pulse of predetermined amplitude and a width equal to the mid amplitude width of an input pulse from an electro-optical label reading system is provided. The present circuit comprises delay line means having a first output terminal and a second output terminal with the signal at the second output terminal being delayed twice the time of the delay at the first terminal. The first output terminal of the delay line is connected to an amplifier operative to double the amplitude of the signal applied thereto. The output of the amplifier is connected to one input of each of first and second comparators with the other input to the comparators respectively connected to the input signal source and the second terminal of the delay line. The output of the comparators is connected to the input to an AND gate with the output from the AND gate providing the desired pulse width information.

摘要： The apparatus is an earth horizon crossing indicator used in a spacecraft attitude control system, which uses power from a self-contained battery rather than power from the spacecraft electrical system. The battery is typically of the lithium thionyl chloride type. This reduces the weight and complexity of the spacecraft attitude control system and allows the resources of the spacecraft electrical system to be used for other devices.

摘要： The attitude of a satellite is determined by using an array of IR detectors receiving an image of space and the Earth. The detectors are spaced so that at least in a central zone, the sun will not enter the optical field of more than one detector. The signals from each detector are monitored and if a signal is very high, indicating that the sun's image is falling on the detector, that signal is ignored.
