摘要:
An absorption mat 1 receives organic hydrocarbons in liquid, paste-like or solid form, for example, oil, fats, fuels and solvents. The absorption mat includes a plate-like molded body 2 made of rubber granulate 3 or rubber shavings 3 bonded to each other to define a plate-like body. A base layer 6 resistant to the hydrocarbons is joined by vulcanization to the plate-like molded body 2. The base layer 6 is a composite base barrier layer including first and second layers (10, 12) made of hydrocarbon resistant material and a mesh-like support layer 14 is sandwiched and trapped between the first and second layers (10, 12) for preventing unwanted stretching of the mat during manufacture and when handling before placement on the ground or floor area and when in use.

A double layer armor for an armored vehicle. At least two elastic retaining mounts are provided between an inner armor plate member and one of a plurality of sections not attached to each other forming an outer armor plate member. At least one of the elastic retaining mounts is formed as an engagable or disengagable pivot mount, while at least one other elastic retaining mount comprises a housing attached rigidly with the inner armor plate member and a core attached detachably with the respective section of the outer armor plate member as well as an elastic member mounted between the housing and the core.

A rail support comprises a ribbed plate having smaller and greater sides and predetermined width and length, the width of the ribbed plate being measured in a direction transverse to the direction of elongation of rails to be supported while the length of the ribbed plate being measured in the direction of elongation of the rails, the width of the ribbed plate being greater than the length of the same, the ribbed plate being provided with openings for passage of connecting elements for connecting the ribbed plate to a foundation, a substantially flat rubber body arranged under the ribbed plate so as to support the latter and having smaller and greater sides and width and length, the length of the rubber body corresponding to the length of the ribbed plate while the width of the rubber body being greater than the width of the ribbed plate so that the rubber body at its small sides extend outwardly beyond the ribbed plate at the small sides of the latter, a shell-shaped frame enclosing the rubber body at its all sides and enclosing the ribbed plate at its greater sides and having a bottom, the rubber body and the bottom of the frame being provided with openings corresponding to the openings of the ribbed plate.
摘要:
A mat comprising an elastic material which serves as an underlay for a ballast bed of crushed stone, metallic particles, or the like is provided with a plurality of projections on its underside and with an upper layer of a material different from the elastic material. This upper layer on the upper side of the mat advantageously comprises a strong fabric. Particularly the upper layer may comprise a multilayered fabric with inlay layers of elastic material positioned between the individual layers of the multilayer fabric as well as a coverying layer of a softer material on the upper surface of the upper layer of the mat. The fabric of the upper layer of the mat advantageously comprises a water and rot resistant plastic material, such as a polyamide.
摘要:
A railroad bed has an elastomeric mat which supports the ballast and on which the sleepers and rails are mounted. The mat has an upper surface formed by a metal or plastic sheet which prevents penetration of the ballast into the elastomeric body.

A shock absorber component 7 is in the form of a flatly placeable strip, plate or mat and is especially for supporting the track of railroads. The shock absorber component 7 is placed between the superstructure 2 and the roadbed 1 of the track assembly. The shock absorber component 7 includes a core layer 8 having bonded rubber particles 12 and a cover layer 10 made of flexible material. The cover layer 10 surrounds this core layer 8. The rubber particles 12 of the core layer 8 are exclusively porous and the cover layer 10 is made of a compact rubber material. The cover layer 10 is vulcanized to the core layer 8.
摘要:
An endless track vehicle wheel which simultaneously serves for guiding the track guiding teeth of a cooperating track. The guiding flanks of the wheel which face the track guiding teeth of the track are protected by wear-protecting rings shrunk onto the wheel.
摘要:
A rail-mounting assembly in which a rigid member supporting the rail is received with clearance in an opening of an overlying rigid body. The clearance has downwardly and inwardly inclined flanks which bear upon a rubber-metal support damping sound, shock and vibration.

摘要:
A ground-borne noise and vibration damping system in which is a track bed formed with rails for a railway vehicle and generating noise and vibration, a structure is to be protected against the noise and vibration; and a damper for ground-borne noise and vibration is embedded vertically in the ground and interposed between the track bed and the structure. The damper has two upright rigid concrete plates defining a vertical gap between them, and an elastic mat sandwiched between the concrete plates and in contact therewith.
