Abstract: A horizontal-axis oil-lubricated cylindrical roller bearing arrangement for bearing traction motors of rail vehicles, including a stationary bearing bracket, a cylindrical roller bearing having an outer ring fastened to the stationary bearing bracket, a shaft on which an inner ring of the cylindrical roller bearing is fastened, and an annular oil chamber arranged coaxially relative to the bearing and having an upper section connected with the bearing by at least an oil outlet in the chamber wall facing the bearing and connected by at least one duct with an oil-catcher device. The oil-catcher device is supplied from a gear case serving as a lubricant oil reservoir and is placed on the inside of the gear case. The oil-catcher device meters the amount of oil to be caught by the catcher device. Feeding of the lubricating oil to the annular oil chamber takes place at a level which is below the oil outlet from the annular oil chamber into the bearing.

Abstract: The color of a standard color is displayed adjacent a sample for direct comparison of the color of the sample with the color of the standard color by a method and apparatus comprising a color standard, a light source for supplying a uniform beam of light of a desired composition and intensity, means for receiving light from the light source and projecting the light onto the color standard, means for receiving light reflected from the color standard and transmitting the reflected light to a display means, and a display means for displaying the reflected light adjacent the sample to permit direct comparison of the color of the light reflected from the color standard with the color of the sample.
