Fabric-reinforced adhesive bonding sheet, the adhesive of which is a blend of epoxy resin and a dianiline which soften and melt at 50.degree.-110.degree. C. The bonding sheet is especially useful for making insulated rail joints.
摘要:
A rail joint bar moulded as a solid component from a reinforced dielectric material, to finished cross-sectional shape and overall dimensions. The bar is shaped and dimensioned to include surfaces which tighten in a wedging action against the head and flange of a rail when bolted to the rail. A pair of the bars are secured on opposite sides of the rail web to form a rail joint, with the bars clear of the rail web by virtue of their engagement with the head and flanges of the rail, thus ensuring that the pair of bars move with the rail during service and retain their clamped position at all times.
