  • Patent number: 7503264
    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.

  • Patent number: 6194358
    Abstract: A method of treating hopper cars to prevent bridging or sticking of bulk commodities during unloading by applying a coating of a mixture comprising pigments including graphite, solvents, resins, a drier/cross-linking/hardening system, and a rheological system. The resin is selected from the group consisting of alkyds, acrylics, polyesters, hydrocarbon resins, rosin-based resins, polyamides, urethanes, and epoxies. The solvent comprises aliphatic and aromatic hydrocarbons. Ranges in weight-percent for each of the components is set forth, as well as a specific formulation.
