  • Patent number: 10525995
    Abstract: A safeguarding system for an emergency fish-plate connector is fastened to a rail base of the rail and has a distance measuring device for supplying a measuring value registering a distance a between the emergency fish-plate connector and the safeguarding system. For transmission of the detected measuring values and of an identifying signal—enabling a locally unambiguous correlation of the emergency fish-plate connector with regard to the track—to a control station, the safeguarding system is equipped with a radio device.

  • Patent number: 9490397
    Abstract: A method for producing an optoelectronic thin-film chip semiconductor device is specified. A conductor structure is applied on a carrier and a multiplicity of optoelectronic semiconductor chips are arranged between the conductor structures. Each of the optoelectronic semiconductor chips includes a layer at a top side. Furthermore, electrical connections between semiconductor chip and the conductor structure are established, for instance using a bonding wire. The semiconductor chips and the conductor structure are surrounded with a molded body. The molded body does not project beyond the optoelectronic semiconductor chips at the top side thereof facing away from the carrier. Moreover, the carrier is removed and the semiconductor chips surrounded by molding are singulated.

  • Patent number: 8398000
    Abstract: The invention relates to a connection element for running rails of a suspended track for receiving the running rails (2, 2?) and a securing device for securing the running rails (2, 2?) against being pulled out of the cavity (H, H?) and a running rail system having multiple running rails (2, 2?), which can be connected by connection elements (1; 11). The invention solves the problem of allowing simple and rapid tool-free mounting with a simultaneous secure connection of running rails of the running rail system in that the securing device of the connection element has at least one spring-elastic first connection claw (8; 12; 15), which projects diagonally in an insertion direction (E) of a first running rail (2) into the cavity (H) in the relaxed state, and/or by a running rail system having connection elements (1; 11) implemented in this way.

  • Patent number: 4485967
    Abstract: A connection for connecting a pair of rail members end to end, each rail member having a base, web, and a railhead. The connection comprises a tongue projecting endwise from the railhead of one rail member into a slot in the railhead of the other rail member, with the top of the tongue generally flush with the top of the railheads and the bottom of the tongue slidable on the other rail member for transmitting loads applied to the top of the railheads. The connection further comprises a longitudinally extending end projection on the other rail member slidable in a recess in the one rail member. The end projection is engageable with the one rail member for limiting the extent of the relative longitudinal movement and for transmitting tension force along the rail members. The connection transmits longitudinal, lateral and downward vertical loads on the rail members while allowing thermal expansion of the rail members, and presents a continuous load bearing surface along the top of the railheads.

  • Patent number: 4466570
    Abstract: An insulated joint is provided for use between sections of rail that are disposed in adjacent signal circuits. The insulated joint includes a separator disposed between a pair of dielectric end posts. The end posts have a plan configuration substantially identical to the cross section of the rail sections with which they are used. The separator is constructed from a material having sufficient strength to enable it to withstand the forces exerted by the wheels of the train. The insulating fabric disposed between the joint bar and the rail is removed at least in the portion thereof adjacent the separator head portion thereby avoiding the problem of having the insulating fabric wear adjacent the separator. In locations where the separator would be subject to greater than normal forces, a head portion with a height greater than that of the rail sections is provided to increase the strength of the separator.

  • Patent number: 4464831
    Abstract: A method of fabricating an insulating joint between a pair of end abutting rail sections of a railroad track includes the suspension of a pair of opposed fishplates at the rail joint at spaced distances outwardly of the rail sides, and simultaneously heating the rail sections and the fishplates to a predetermined temperature for activating a heat-activatable adhesive provided in fabric cuffs which are disposed between the fish surfaces and the fishplates. The fishplates are shifted along guide rods of their support assemblies inwardly toward one another into place against opposed fish surfaces of the rail sections, and are thereafter bolted in place. A device for fabricating the joint includes a box-like hood on which heaters are mounted, or a shear assembly supporting the heaters and being clamped onto the rail head. The heaters may be adjusted to accommodate various rail profiles.

  • Patent number: 4273284
    Abstract: A rail joint includes an insulative base piece formed of a synthetic plastic composition and insertable between a rail base flange and a joint bar. The opposite surfaces of the base piece are provided with elevated ribs or serrations extending longitudinally of the length of the base piece which base piece is at least as long as the joint bar. Longitudinal migration of the base piece during travel over the rail joint is resisted and thus retention of the base piece is enhanced, due to the deformation of the ribs as the base piece is sandwiched between the rail and joint bar and irregularities in the opposed joint bar and rail base surfaces are filled by the compressed and deformed ribs.

    Abstract: A rail track that reduces noise and vibration for particular use in rapid transit and subway lines. The track is formed of a conventional rail embedded in a pre-stressed concrete bed. Sections of such jacketed rails are joined together by means of flanges, one of which is welded to one side of each rail end, with the bolt holes in the flanges and the joined rails oriented at an angle to axes of the rails so as to transfer a tension load between each rail of a joint. The pre-stress tension wires of the concrete bed extend beyond the ends of each section and are individually joined by turnbuckles or other tension creating couplers. The bottom of each concrete bed section is mounted on a solid sheet of rubber or other elastomer.
