Abstract: A side bearing assembly for a railway vehicle includes a cage, a cap coupled to and moveable relative to the cage, and an insulator disposed between the cage and the cap. The railway vehicle includes a bolster extending laterally and a car body disposed on the bolster. The cage is attached to the bolster and the cap supports a portion of the car body such that the side bearing assembly is disposed between the bolster and the car body to dampen lateral pivoting of the car body relative to the bolster. The insulator is formed of microcellular polyurethane for resiliently deforming and storing energy during compressive movement between the car body and the bolster through a range of temperatures between ?40° C. and 80 ° C. Microcellular polyurethane maintains flexibility at this temperature range such that the side bearing assembly maintains its ability to dampen lateral pivoting through this temperature range.

Abstract: A uretonimine-modified isocyanate composition has reduced color. The uretonimine-modified isocyanate composition comprises a polyisocyanate composition having two or more isocyanate groups and comprising 4,4?-diphenylmethane diisocyanate (MDI) and a catalyst for catalyzing a reaction of the isocyanate groups to form carbodiimides available for forming uretonimines and uretonimine oligomers.

Abstract: A mount assembly having a support structure mounted to a frame of a vehicle and a carrier mounted to a vehicle body. The support structure is displaceable relative to the carrier along a central axis (L). The support structure defines an inverted cup having a bottom with an aperture and a cylindrical skirt on a central axis (L) extending below the frame.
