Abstract: A system (10) for sensing a condition of a rail vehicle undercarriage component (e.g., 18) includes a sensor (e.g., 12) comprising an array of infrared sensing elements (29). Each of the elements may be aimed at a different region of a target area (e.g., 32) of a rail vehicle undercarriage component to generate respective scanning waveform signature data corresponding to each different region. The sensor may be oriented so that at least one of the elements receives unobstructed infrared emissions (e.g., 33) from the undercarriage component of a rail vehicle passing the sensor. The system also includes a memory (42) for storing characteristic waveform signature data corresponding to known undercarriage components.

Abstract: A method of producing hydroxylammonium salts by catalytic reaction of nitrogen monoxide with hydrogen in a diluted aqueous solution of mineral acid in the presence of platinum catalysts suspended on a support in multiple subsequent reaction stages. This reaction takes place in a stirred reactor wherein a gas inlet and distribution system is provided in the lower part of the stirred reactor, a disk agitator is placed immediately above, the hub with bearing surface or support mounting angled, concave and tilted agitator blades that rotate their angled or concave sides in the direction of motion, and a two-blade agitator is provided on the agitator shaft in the upper part of the stirred reactor, its individual leaves being offset like lamellas so that they constantly wet the reactor cap when rotating.

Abstract: This invention relates to a method for producing an aqueous solution of free hydroxylamine (HA) by simultaneous countercurrent treatment of a HA salt with ammonia or ammonia water, then separating the HA by distillation and reconcentrating the aqueous HA solution in a countercurrent with a stripping medium. The stripping medium used according to the invention is a mixture of steam and a non-condensable inert gas and the process temperature at a defined pressure is controlled by the quantity of non-condensable inert gas at the column inlet. The preferred non-condensable inert gas is nitrogen. This results in increased safety and a reduction in losses of the method for producing aqueous solutions of free HA.
