Abstract: The recycled crumb rubber coating is a corrosion-proof coating for piping and the like. The coating is formed from recycled crumb rubber mixed with an epoxy resin and a hardener. Crumb rubber is first mixed with a liquid epoxy resin. An agent for reducing the viscosity of the liquid epoxy resin may also be added. A hardener is then added to this mixture. Finally, powdered crumb rubber is added and mixed to form the recycled crumb rubber coating. The total crumb rubber forms about 23-24 wt % of the coating, the balance being epoxy. The epoxy has liquid epoxy resin and a hardener in a ratio of about 2:1 by weight. The epoxy may also include a viscosity reducing agent of about 1% of the total weight of the liquid resin and the hardener. The crumb rubber may be a blend of powdered crumb rubber and mesh crumb rubber.

Abstract: A moveable track cover is provided for use with a mechanism configured to move along a track. One example of such a mechanism is a pipe racking system used on off-shore oil and gas platforms. One end of the moveable track cover is connected to the pipe racking system mechanism which moves along the track. The other end of the track cover is spooled onto a drum. Rotation of the drum is controlled by a motor which exerts enough force to maintain the track cover in constant tension. When the pipe racking system mechanism moves towards the drum, the motor rotates the drum to roll the track cover onto the drum. When the pipe racking system mechanism moves away from the drum, it pulls the track cover off of the drum. By attaching a track cover to each side of the pipe racking system mechanism, the track along which the pipe racking system mechanism travels is kept covered at all times. The track cover may be constructed of a sheet of stainless steel strengthened by rib assemblies.

Abstract: A method of making a polymer coated rail in which a rail to be coated (10) is positioned on a mould base (11) in an inverted manner, so that the head (12) of the rail is immediately adjacent the base plate (11). Then, mould side pieces (13, 14) are secured to the base plate (11) to run parallel to the side of the rail (10). Antislip material such as bauxite or granite chippings (21) are positioned in the mould so that they lie on the base plate (11), and then the liquid polymer is poured into the mould to fill the spaces (19, 20) and so encapsulate the rail (10). The polymer is poured into the mould, until its surface (22) covers the foot (23) of the rail. In this state, the polymer is allowed to cure, so that it solidifies, and once the side plates (13, 14) have been removed, the rail together with its polymer coating can be lifted from the base plate (11).

Abstract: Pre-cast concrete panels are commonly provided at road-rail crossings, to serve as the roadway, but such panels have been liable to premature failure. Rubber caps are placed over the cross-ties, between the panel and the ties, to isolate the panel from the stresses that arise when the panel contacts the ties directly. The caps are ribbed. Two kinds of ribs are provided, some solid and rectangular, others triangular and hollow. The ribbed panels provide resilience and hysteresis over a range of conditions, to prevent fretting and cracking of the panel.
