  • Patent number: 8272332
    Abstract: An overhead mass transportation system for cities and urban areas may be particularly suitable for environmentally acceptable, or “green”, systems because it can be used to produce power by an optional super solar system deployed, for example, over the tracks. The mass transportation system may meet many current economic and environmental needs. In many urban areas around the world, the mass transportation system can replace buses and taxis on the street, with their noise and pollution, and reduce the use of oil and fuel. The system can also be used for inter-cities transportation, where in can dispense with the need to carry large amounts of fuel for long distance transportation. The system may also be suitable for areas with challenged trains, such as those areas with a high level of floods, snow, or the like. Furthermore, the system may be suitable for desert transportation or transportation over waterways or between islands.

  • Patent number: 7996824
    Abstract: A synthetic benchmark for a computer program and a method and computer program product for creating a synthetic benchmark for a computer program. The synthetic benchmark is created using statistical information that is collected about an executing program, and some hints about the machine on which the benchmark will be run. When executed, the synthetic benchmark exhibits behavior similar to the computer program to permit computer performance to be accurately measured.

  • Patent number: 6905509
    Abstract: A catheter and method are provided for modifying a temperature of a patient. The catheter includes a heat transfer element (“HTE”) having surface irregularities shaped to create turbulence in a surrounding fluid. The catheter also includes a supply catheter to deliver a working fluid to an interior of the heat transfer element and a return catheter to return a working fluid from the HTE. A guidewire lumen is provided to receive a guidewire. The guidewire may have a temperature-monitoring device disposed at its distal tip from which feedback may be provided to control the temperature of a source of the working fluid.

  • Patent number: 4919056
    Abstract: Shelf conveying system which is guided within one upper track system (8) and one ground track system (7), has driving bogies (3), which are supported by wheels (10) on two bearing surfaces of the track system (7) and are equipped with guide rollers (12), which abut laterally on the track system and can be removed at the branches for a straight-ahead path or to introduce branch paths. In addition, each driving bogie has at least one pilot roller (13) which extends into the gap between the bearing surfaces. The pilot roller (13) can be simultaneously designed as a track fastening element (14) which effectively connects with the track by contact with the back taper surfaces of the ground track system (7) (FIG. 3).

  • Patent number: 4555828
    Abstract: A guiding system for movable suspended partition walls comprising a main guide rail and two or more branch guide rails each extending from one side of the main guide rail to define two or more directional change points, a plurality of retainers movably disposed within the guide rails and suspending therefrom a plurality of partition walls, and guide members to select directions of movement of the retainers so that selected one or ones only among the retainers can move from the main guide rail into a selected one of the branch guide rails or vice versa without bringing the retainers to a stop at the directional change points.

  • Patent number: 4516504
    Abstract: A conveying and storage system for wheeled pallets has tracks each formed by a pair of generally parallel rails. The pallet has grooved wheels at one side for riding on the upper edge of one rail and a roller on the other side for riding on the upper edge of the other rail. At the intersection of the tracks, the two wheel engaging rails are interconnected by a frog on which the peripheries of the grooved wheels roll. Where a wheel engaging rail crosses a roller engaging rail, the roller engaging rail is interrupted and elevated pads are provided that are coplanar with the upper edges of the rails. The pads are arranged to support the rollers as they negotiate the gap in the roller engaging rail.

  • Patent number: 4290367
    Abstract: The overhead conveyor comprises a main track and a branch track connected to the main track in a switch point, the tracks having a shape of a box-like beam with a longitudinal slit in its bottom flange for suspending a trolley carriage, the carriage supporting a rocking lever having at its ends guiding rollers, the operation of the switch point being safeguarded via tiltable tongues arranged on the lower flange of the track and cooperating with slide shoes provided on the ends of the rocking lever, and by means of locking rails attached to the side walls of the track to lock the rocking lever in the desired angular position; the ends of the rocking lever further support safety noses each having an inclined surface of a length sufficient for bridging the gap between the ends of the inclined tongues and the beginning of the locking rail when the slide shoe still engages the end portion of the safety tong.

  • Patent number: 4068598
    Abstract: The invention relates to an element of a vehicle which is part of a continuously moving train of similar vehicles, the element consisting, on the one hand, of two axles carrying wheels with solid tires and inner tubes and, on the other, of an on-board shunting device essentially consisting of a bistable rocking assembly operated by fixed ramps in relation to the track. The element of the vehicle also comprises pivoting bearings (6,6') which are part of the bistable rocking assembly (7) and are located in the vicinity of the axles (3,3'). The bistable rocking assembly (7) is operated and locked through an eccentric (13). Shunting wheels (8,8') are carried by the bistable rocking assembly (7) and cooperate with the external surfaces of the rails along which the element of the vehicle travels or with counter-rails arranged against the external surfaces.
