Abstract: A table can be folded in the interior of a motor vehicle and comprises a table top arranged on a vehicle-mounted support so that the table top can be moved from a resting position, in which the table plane is oriented substantially vertically, into a usage position oriented substantially horizontally. The support extends in the longitudinal direction of the vehicle and the table top is fastened to the support so the table top can be pivoted by a table top retainer from the vertical resting position into a horizontal position about a pivot axis in the longitudinal direction of the vehicle. The table top and/or the table top retainer can be locked in the usage position by a locking device when the table top is in the horizontal position and/or in the vertical position.

Abstract: A homogeneously illuminating ophthalmic instrument includes an illumination device having a source of illumination, a homogenizing unit and a projection device, at least one organic or inorganic source of radiation with spectrally selective emission being used as a source of illumination. The illumination generated in this way enables correspondingly adapted visual and/or digital observation, recording or display of the examined regions of the eye by a visualizing unit.

Abstract: In a computer modeling method for the core of a nuclear reactor the core is divided into a plurality of primary grids in the form of coarse mesh cells. A sub-section of the core relating to at least one grid is assigned to that grid. The sub-section includes that grid and a buffer zone that surrounds the grid horizontally and contains at least the grid that lies immediately adjacent to the first grid. The sub-section is sub-divided into a plurality of secondary grids—fine mesh cells—that are smaller than the primary grids. In a first computing step, a model of the core is calculated using a nodal calculation method, based on a respective dataset that is assigned to each primary grid. In a second computing step, a respective second dataset is assigned to each secondary grid of a sub-section and a model is then calculated for the sub-section, based on the dataset and the flows on the border of the sub-section that have been calculated in the first computing step.

Abstract: The fuel injection system has one high-pressure fuel pump and one fuel injection valve for each cylinder of the engine. The fuel injection valve has a first hollow injection valve member and a second valve member guided displaceably, inside the first valve member for controlling first and second opening(s), respectively into the associated engine cylinder. The second valve member is movable by the pressure prevailing in a pressure chamber in an opening direction counter to a closing force and is acted upon at least indirectly by the pressure prevailing in a fuel-filled control chamber, which pressure is controllable as a function of operating parameters of the engine such that the second injection valve member, by means of the pressure prevailing in the control chamber, can be blocked, independently of an opening motion of the first injection valve member in a position that closes the at least one second injection opening.

Abstract: The fuel injection system has one high-pressure fuel pump (10) with a pump work chamber (22) and one fuel injection valve (12), communicating with the pump work chamber, for each cylinder of the engine. The fuel injection valve (12) has a first injection valve member (28), by which at least a first injection opening (32) is controlled, and which is movable in an opening direction (29) counter to a closing force by the pressure generated in the pump work chamber (22).

Abstract: A fuel injection valve for internal combustion engines, having a valve body with longitudinal bore terminating in a valve seat. In the region of the valve seat, at least one injection opening connects the bore with the combustion chamber of the engine. A valve member disposed in the bore cooperates with the valve seat for controlling the at least one injection opening. Between the wall of the bore and the valve member, a pressure chamber is embodied that can be filled with fuel at high pressure. The valve body is surrounded, in the region of the pressure chamber, by a sleeve that has anisotropic strength properties, so that the valve body exhibits less deformation from the pressure in the pressure chamber.

Abstract: A fuel injection valve for internal combustion engines, having a valve body (1) in which a bore (3) is embodied that has a longitudinal axis (14), and on the end toward the combustion chamber of which bore a valve seat (17) is embodied. In the region of the valve seat (17), at least one injection opening (20) is disposed that connects the bore (3) with the combustion chamber of the engine.
