Abstract: The invention relates to a motor vehicle body, the support structure (10) of which is composed of large-size partial modules (12, 34, 50, 66), a basic module (12) comprising lateral longitudinal members (15) and a body floor (14) and reaching laterally as far as front wall columns (20), and, when the support structure (10) is assembled, the basic module (12) being connected to a front end module (34) which belongs to the front crumple zone of the motor vehicle and is supported in a crash stable manner on the basic module (12). In order to provide a motor vehicle body, in which the front end module (34) even without a roof construction is fixed in a sufficiently stable manner on the basic module (12), a front end region (36) of the body floor (14) belongs to the front end module (34) and extends rearward over a considerable length region of the basic module (12) between lateral longitudinal member sections (16).

Abstract: A covering part for mounting on a front wall of an occupant compartment of a vehicle, having an instrument panel and a center console which starts in the center on a lower instrument panel area and continues in the longitudinal direction of the vehicle occupant compartment. For providing a sufficiently large free surface for a combined accommodation of a plurality of operating elements with or without control and display elements in a cohesive operating unit and of large-surface air outlet openings, the instrument panel is constructed with a hood-shaped center part which extends in a diagonally sloped manner with respect to the center console and changes into the center console at the end side. The center part is provided with a bridge console spanning the center part at a distance from its front surface, which bridge console extends from the upper instrument panel area to the center console.

Abstract: A passenger cell for a passenger car with a load bearing shell structure. The A-pillar and the adjoining lateral roof frame each have a two-part longitudinal profile. The two longitudinal profile parts are arranged at a distance from each other and an inner longitudinal profile part protruding into the interior as a roof gripping rail.

Abstract: Device for shutting down a high-temperature nuclear reactor having a reactor core, including a reflector disposed outside the reactor core, channels being disposed in the reflector and having lower ends, storage bins being disposed above the reactor core and being in communication with the channels above the lower ends thereof, a neutron-absorbing material formed of fluidic bodies being storable in the storage bins and feedable into the channels, a plurality of lines connected between the lower ends of the channels and the storage bins, means for selectively establishing an upwardly directed fluid flow of the material in one of the plurality of lines for conveying the neutron-absorbing material at a given adequate speed from one of the channels into one of the storage bins.

Abstract: Pebble-bed nuclear reactor capable of being shut down by a fluidized mass of bodies containing neutron-absorbing material, the fluidized mass of bodies being received in a storage container disposed above the pebble bed during normal operation of the reactor, the storage container being formed with a closable discharge opening, including a piston rigidly connected to the storage container and disposed below the discharge opening thereof, the piston being guided in a cylinder stationary relative to the reactor and being open at the top thereof, the storage container being displaceable in vertical direction between upper and lower end positions thereof, the piston, in the upper end position of the storage container, closing off the cylinder at the upper edge located at the open top of the cylinder and, in the lower end position of the storage container, the fluidized mass of bodies discharged from the discharge opening of the storage container being formed on top of the piston into a discharge cone having a hei
