Abstract: A sliding wall arrangement includes at least one wing and a running rail that can be sunk in a building floor and has at least one guide channel in which the at least one wing is displaceably mounted at the lower edge. At least one covering element is provided, which serves for covering the at least one guide channel if the guide channel is freed from the at least one displaceable wing. The at least one covering element has a raised state in which it covers the guide channel freed from the wing, and a lowered state in which it is lowered into the at least one guide channel, with the result that the at least one wing can be displaced across the at least one covering element.

Abstract: A road system comprising a finished road surface and a geofoam positioned below the road surface, where the geofoam includes a foam core and a facer including a fibrous mat and an interfacial region disposed between said foam core and said fibrous mat.

Abstract: A track cover comprising slab-shaped cover elements (7) arranged between the rails (3) of the track (2) on rail level and, preferably, also slab-shaped cover elements (8) outwardly adjoining the rails (3). The cover elements (7, 8) comprise supporting bodies (9) at their rims (10) which face the rails (3), the cover elements resting on the rails (3) by means of these supporting bodies. The supporting bodies (9) which are arranged on the cover elements (7, 8) at their rims (10) that face the rails (3) are mounted on these cover elements so as to be shiftable in the rail-longitudinal direction (11). It is suitable if on each rim (10) of the cover elements (7, 8) that faces a rail (3) which is provided with the cover, at least two supporting bodies (9) are shiftably arranged. Preferably, the supporting bodies (9) are mounted to be shiftable in the rail-longitudinal direction (11) and to be pivotable about a geometric axis extending in parallel with the displacement direction.

Abstract: The invention relates to track system having two substantially parallel tracks (6) which are disposed on respective concrete slabs (1) of a fixed track. The slabs (1) comprises a plurality of track supports (2, 2?) for receiving and fastening thereon two parallel rails (5). The top surfaces (3) of the slabs (1) of the two tracks (6) are inclined independent of the a guiding system of the tracks (6) and of the corresponding position of the rail supports (2, 2?) relative to the two outer sides (8) of the track system and form a slope. The invention also relates to a concrete slab of a fixed track, which comprises supports (2, 2?) for the first rail (5) which are higher in relation to the top surface (3) of the slab (1) than the supports (2, 2?) for the second rail (5).

Abstract: A rail cover and support for mounting and insulating the rails of an electric transit system in which the rail cover is vulcanized both to the rail and outer skid support at the manufacturing site prior to delivery to the field and a rail cover completely surrounds both the base flange and web portion of each rail and terminates along the undersides of the top flange. In one form, the upper free ends of the rail cover are increased in thickness to form bumpers along opposite sides of the rail to cushion it against undue shifting or vibration. In fabricating the rail, a sheet dielectric material is vulcanized to the rail with or without a skid plate.

Abstract: A concrete gauge panel spans the gap between two parallel railroad tracks. Two concrete field panels lead from the roadway surface to the railroad tracks, one panel on each side of the railroad tracks. A spacer sits between the concrete of the concrete field and gauge panels and the railroad tracks. The spacer is affixed to the panels in a way that allows the spacer to be removed and replaced without replacing the entire panel.

Abstract: A system for embedding a pair of rails of a railway track comprises a pair of field panels adapted for positioning opposite each other at outer sides of the rails and a gauge panel adapted for positioning between the rails. Each field panel has a side surface adapted to face its corresponding rail outer side and the gauge panel has opposite side surfaces adapted to face the inner sides of the rails. A first filler strip is associated with each of the field panels and a pair of second filler strips are associated with the gauge panel. Each of the first and second filler strips include a sealing portion that is adapted to contact one of the inner and outer rail sides and a mounting portion for connecting the filler strip to its respective panel. A U-shaped reinforcing member extends along a length of each filler strip mounting portion such that each filler strip is sandwiched between its respective reinforcing member and panel side surface.

Abstract: A railway grade crossing apparatus comprises at least one rectangular gauge panel of precast concrete with resilient bumpers on opposing sides for closely fitting between the rails and rectangular field panels of precast concrete, each having a resilient bumpers on one side for placement between the outside of each rail and the adjacent road abutment, the gauge and field panels having means for attaching lifting a device to the top surface of the panel, and the method of installing said apparatus comprising lifting the panels into place with a bumper abutting the side of a rail, and exerting a lateral force on the panel toward the rail to compress the bumper whereby the opposite side may be urged downward into place and releasing the lateral force to allow the resilience of the compressed bumper to adjust the lateral position of the panel to a final position between the rails or rail and road abutment.

Abstract: A structural arrangement for an embedded and sealed railroad track and a method for its installation to provide a gutter defined along the rails of such a railroad track extending along or across a street or highway with rail tops at pavement level. Rubber filler bodies are held in place along the sides of each rail by retainer strips which lock into place on the filler bodies. A retainer form holds the filler bodies in place and provides space for the retainer strips when pavement materials are cast in place along the rails. Protective caps and sealing structures are installed before pavement materials are cast in place, to exclude the paving materials from space needed as a gutter along the rails to provide access to the rails and to spaced-apart supporting structures to which the rails are fastened, and to keep foreign materials from getting on the top of the rails and prevent them from becoming caught between the rails and the adjacent filler bodies.

Abstract: A plurality of timbers connected to ties at a railroad grade crossing. Hooks are connected to some of the ties. When the timbers are disposed on the ties, the hooks are inserted into the timbers. Pins are disposed through the ties and through portions of the hooks for connecting the timbers to some of the ties. The timbers are connected in groups of two or three timbers to form field deck panels and gauge deck panels.

Abstract: Railway track is laid by supporting the rails in spacers above a pair of parallel flexible tubes, which are then filled with aggregate under pressure to contact the feet of the rails and to curl around the feet so that when set the rail is continuously supported and no sleepers or ballast are required.

Abstract: A sensing system for use on a tracked vehicle transporation system forms a sensitive floor beneath the lip of a platform. The floor is made up of a plurality of metal plates mounted on spring supports so that they can be slightly depressed if an abnormal load is applied to them. Such depression changes the state of a switch or like means through the intermediary of a cable and a lever.

Abstract: A railroad grade crossing is provided with elastomeric decking pads presenting an upper, vehicular crossway substantially coplanar with the tops of the metallic rails, in turn, secured to the spaced cross ties therebeneath which rest on the roadbed of the roadway. Deck-supporting grillage structure, supported by the cross ties includes a series of spaced cross beams of metallic material arranged to preclude the transmission of electrical currents across the rails. The grill is also provided with spaced, non-metallic, longitudinal beams between the I-shaped cross beams and the deck. The longitudinal beams, to which the deck is attached, rest on the cross ties and are tied to the cross beams. Because of the unique suspension principle which the crossing employs, no drilling of holes in the cross ties is required, nor is any type of fastening to the cross ties required.

Abstract: The exposed ends of railroad grade crossing platforms are protectively capped with elongate devices which provide ramps sloping downwardly and away from the surface of the platforms along the ends of the grade crossing. The ramps deflect air hoses, chains, etc. which occasionally hang downwardly from railroad cars and locomotives passing over the grade crossing, and, thus, prevent the free ends of such items from being caught on or damaged by the otherwise exposed ends of the grade crossing platforms. Ramp-supporting members extend in mutually spaced relationship from the underside of the ramp of each device so that in end view, the device has the shape of essentially a right triangle, whose hypotenuse is on the ramp surface and whose legs are partially formed by the respective supporting members and partially by the ramp. The opposite legs of the triangular shape are preferably unequal in length so that the cap devices can accommodate two different platform heights.
