INTERMEDIATE PIECE FOR CONNECTING MANGANESE STEEL MOLDED BODIES WITH CARBON STEEL AND METHOD FOR CONNECTING MANGANESE HIGH-CARBON STEEL CAST PARTS TO CONTROL RAILS
The invention relates to an intermediate piece for connecting manganese steel molded bodies with carbon steel, in particular manganese high-carbon steel cast cores to control rails, the intermediate piece comprising steel of the group of austenitic-ferritic compound steels having a ferrite portion of < 60% by weight. The method for connecting manganese high-carbon steel cast parts to control rails is characterized in that an austenitic-ferritic intermediate piece comprising a compound steel having < 60% by weight of ferrite is welded to the manganese steel cast part and the control rail.
A rail fastening apparatus fastens an inner stock rail in a railway slide chair assembly. The apparatus includes a base plate. The base plate has on one face a rail seat region on which the inner stock rail sits when the slide chair assembly is in use. A resilient rail fastening clip restrains the inner stock rail. A locating means locates the rail fastening clip in a first position. A loading means vertically deflects the clip so as to produce a load in a toe portion of the clip. A second locating means holds the rail fastening clip in a second position different from the first position such that the toe portion of the clip sits on a ramp of the loading means in a preload condition in which the clip does not bear on the rail
Disclosed is a device for supporting the reversing movement of point blades (4) of a switch. Said device comprises rolls (5) which embrace the point blades (4) during at least part of the reversing movement thereof and are mounted on a lever (6) that is pivotable against the force of a spring (9). The pivotable lever (6) is mounted inside a frame or cage (8). Means are provided for fastening the frame or cage (8) to a tie and/or a rib plate (1). Said means allow the frame or cage (8) to be fastened to the surface of a tie, especially laterally outside a slide chair (2). The spring (9) is disposed between the upper surface of the tie and the lever (6), at a distance from the swivel pin (7) of the pivotable lever (6).
The invention relates to a device for the contactless determination of the energy requirements of a point actuating drive (7), comprising asynchronous motors which are connected to a three-phase current source (1) via conductors. According to the invention, at least one inductance coil is mounted in parallel to a phase conductor and the conductor that is connected to the inductance coil is guided in the opposite direction at or through a sensor (5), wherein the blind current component produced in the throttle (4) compensates at least partially the blind current component that is, in addition to the effective power component, contained in the line which is guided via the motor winding.
In a device for raising a switch rail (3) of a set of points when the switch rail (3) is switched over, having a roller mount (8) for rollers or drums (14) which is arranged laterally outside a sliding chair within the surface of a sleeper (18) facing the rails (3, 5), the roller block (8) is connected to a flange (9) which supports a stop bar (11), for securement to the rib plate (1), and the stop bar (11) bears laterally against an edge of the rib plate (1) in the position in which said stop bar (11) is connected to the rib plate (1).
