Abstract: A process for detecting oil or lubricant contamination in a manufactured product, the process comprising adding at least two fluorescent taggants to oils or lubricants contained in processing machinery for said product, irradiating said product, causing at least one of said taggants to fluoresce and detecting radiation emitted by said fluorescing taggant in an oil-contaminated product.

Abstract: An expansion joint for a solids return system includes a female joint portion, a male joint portion received by the female joint portion, the male joint portion and the female joint portion forming a lateral breach therebetween, a double rope seal positioned within the lateral breach, the double rope seal being configured to accommodate relative lateral movement between the female joint portion and the male joint portion, and an insulating pillow received about the male joint portion and abutting a distal end surface of the female joint portion, the insulating pillow being configured to accommodate relative axial movement between the female joint portion and the male joint portion.

Abstract: A process for detecting oil or lubricant contamination in a manufactured product, the process comprising adding a fluorescent taggant to oils or lubricants contained in processing machinery for the product, irradiating the product with radiation, such as infrared or ultraviolet radiation, and detecting radiation emitted from the irradiated product.

Abstract: The velocity of a railway car travelling along a particular track can be determined by measuring the distance travelled by the car during a predetermined time interval. This distance travelled is measured by determining the location of the car with respect to a fixed point on the track at two different points of time. The determination of the location, in turn, is found by measuring the time period that it takes an electric signal applied at a fixed signal generating point to travel along the railway track and, once reaching the car, to be reflected back along the track to the signal generating point. By measuring the time delay between the applied signal and the reflected signal, the distance between the application point and the closest railway car on the track can be measured.
