Abstract:

The present invention relates to a method of manufacturing an all metal, single or dual, flanged composite railroad wheel for rollingly engaging a metal rail. A unitary metal railroad wheel having at least one radially extending wheel flange, for intermittently engaging the side surface of the rail, is provided with a metallic inlaid material having a coefficient of friction lower than the coefficient of friction of the wheels main body. The inlaid low friction material forms an annular band circumscribing the inside surface of the wheels radially extending flange.

Abstract:

Seal assemblies are provided. In one embodiment, an example shaft seal assembly comprises an immiscible fluid and a reservoir structure. The immiscible fluid is immiscible with respect to a contained internal fluid in an enclosure with a penetrating shaft. The reservoir structure is disposed in close proximity to the shaft, and the reservoir structure contains the immiscible fluid. The immiscible fluid of the seal assembly provides a fluid barrier to the internal fluid to limit loss of the internal fluid over time.
