Abstract: The storable glass tube sealed on both sides contains the two components of a two-component adhesive and fibers or chips incorporated therein in separate sections which are in immediate contact, being located in said glass tube such that there are portions of both components present at as many as possible intersecting planes perpendicular to the longitudinal axis of said glass tube.
Abstract: The process for the temporary consolidation of railroad track ballast, in particular during the time of redevelopment or reconstruction of a parallel set of tracks, is performed in that the ballast is cemented partially in particular in the side area by a multi component adhesive, wherein this cementation may be broken up mechanically later without affecting reuse of the ballast.
Abstract: In the process of the invention, multi-component resins are applied to porous, granular materials intended for subsequent consolidation. Application is carried out by feeding the components, physically separated from each other, under relatively high pressure, to a mixing chamber, mixing them by turbulent means in the mixing chamber, and applying the resulting mixture, at relatively low pressure, as a thin curtain in laminar flow to the material. The simplest form of the device of the invention comprises: a) separate feed lines for the components at relatively high pressure; b) a mixing chamber preferably designed as a static mixer; c) a fan spray nozzle working at relatively low pressure. The process and device are used to increase the sound-absorption and/or ease-of-cleaning characteristics of a railway tracks, to increase the cross-sliding resistance of railway sleepers on ballast, and to smooth the transition between a soft and hard railway track.
