Abstract: The invention relates to a profiled rail (1), especially for a railway track, with a reduced total radiated noise level when in use. In order to reduce the noise radiation level, at least one web side surface (31) is substantially concavely rounded without any salient points in the lower region (31′) between the transition edge (32) on the side of the rail patten (3) and the center of gravity axis (X) in the rail cross-section and/or the height (H) of the pattern is increased by comparison with a normally profiled rail having a corresponding total rail height A.

Abstract: A profiled rolling stock, in particular a running rail or railroad track made of an iron-based alloy, is provided. The alloy contains silicon plus aluminum below 0.99 wt. % of the rolling stock. A structure in the cross section is formed, at least partially, by isothermic structural transformation due to accelerated cooling from the austenite region of the alloy to a lower intermediary phase temperature and holding. Transformation preferably occurs between the martensite transformation point of the alloy a temperature 250.degree. C. over the martensite transformation point Ms.

Abstract: The process and the appropriate apparatus for producing rigid foam elements, in particular of polyurethane, operate with a double-belt unit, in which the rigid foam elements produced are provided with upper and lower cover sheets. A parting agent is applied on the lower cover sheet in a particular region in order to permit subsequent removal of the upper cover sheet and the ridge foam in this region, so that the lower cover sheet projects, and foams an overlapping section during subsequent use as a roofing element or the like. The invention permits a very precise cut to be made by means of the sawing apparatus at the end of the double-belt unit, taking into account the application of parting agent at the beginning and, if necessary, the movement of the sawing apparatus itself.

Abstract: One or more projections are formed, and insulation is stripped, at interconnection areas along one or more conductors, e.g., plural conductive paths in a flat flexible cable, employing apparatus which comprises three rotary members. One or more protuberances on a first rotary member cooperate with a compliant backing surface on a second rotary member so as to form a projection in a conductor about each protuberance. Continued rotation of the first rotary member brings the insulation on each projection into contact with an abrasive surface on the third rotary member, while the protuberance on the first rotary member, about which the projection has been formed, serves as a backing surface to maintain the shape of the projection as the insulation is removed by the abrasive surface.
