  • Making fixed railway track
    Patent number: 7641127
    Abstract: A track system is made by setting a longitudinally extending row of concrete high-pressure injection piles in grown soil and then positioning atop the piles a succession of sleeper frames each including a pair of longitudinally extending rigid concrete beams held together transversely by a rigid steel structure. A longitudinally extending body of concrete is then cast between the beams around the steel frame. Finally longitudinally extending rails are fastened atop the beams.

  • PRESSURE RELIEF DEVICE
    Publication number: 20090173393
    Abstract: The invention relates to a device for internal pressure relief of a pig movable through a pipeline and/or some other pressure-tight sealed working implement introduced into an external pressure medium and having a pressure relief valve. To increase the classification for operational reliability, it is proposed that at least one rupture disk be placed downstream of the pressure relief valve in the pressure relief direction.

  • Fixed track for rail vehicles and method for production thereof
    Publication number: 20060124760
    Abstract: The invention relates to a fixed track for rail travel, comprising a frame-type construction (3, 4, 10). Unlike previous fixed rail tracks made by various producers and suppliers, the invention provides a simple and low cost construction offering variable modification of track and operational profile provided by a gravel construction without the previously indicated disadvantages.

  • Method and apparatus for extracting water
    Patent number: 5729981
    Abstract: The invention relates to a method of extracting water from the ambient air by condensation of air moisture, characterized in that a heat-insulating partition is cooled on one side and heated on the other side by external supply of energy, creating a natural convective air draft on the heated side of the partition, the convective air draft being channelled substantially like a chimney draft and used to recover part of the energy while water is extracted on the cooled side by condensation of air moisture. The invention further relates to an apparatus for carrying out said method. The object underlying the invention is to ensure an appropriate afflux of air and a high degree of efficiency by optimum exploitation of energy.
