Abstract: 2.1 The invention is based on the object of creating a lightning and overvoltage protection device for screened cables by means of which overvoltage levels on the cable screening inside unscreened rooms, resulting from lightning strikes or EMP events, are reduced to tolerable limits. 2.2 This object is achieved in that an earthing system is connected to the cable screen (2) in each case on the outer and inner side of the room boundary (10) in the region of the insertion point of the cable (1), in that the earthing systems consist of a circumferentially contacting cable duct (5, 13), a large-area dissipation plate (4, 12) and an earthing conductor (7, 14), in that the cable (1) has a mutual inductance between the outer (4) and inner (12) dissipation plate which consists of the line inductance (11) of the cable screen (2) and of at least one ferromagnetic surround (21), and in that the surround (21) is electrically insulated from the outer dissipation plate (4) and is electrically short-circuited to the inner dissipation plate (12). 2.3 The invention is used in lightning and overvoltage devices for screened cables which are introduced into unscreened rooms and whose cable screening is earthed to a connected earthing conductor at the introduction point. <IMAGE>

Abstract: A method of connecting a wire segment, such as a stator coil lead, to a terminal having a tang and severing the wire segment at the terminal including the steps of gripping the wire segment by gripper jaws of an industrial robot, manipulating the gripper jaws to lay the wire segment between one aide of the tang and the adjacent face of the terminal, loop the wire segment around an edge of the tang, extend it past the tang, bend it over an edge of the terminal, and pull it with sufficient force that it stretches and breaks at a corner of the terminal edge. The wire segment is initially gripped with a sufficiently low pressure that it can slide along the gripper jaws as it is being manipulated to connect the wire to the terminal. The gripping pressure is increased prior to the pulling step so that sufficient pressure is applied that the free end of the wire segment is held clamped and will not be drawn through the gripper jaws when the wire segment is being stretched and severed.

Abstract: A high-pressure control valve (2) used in chromatography serves as a counter pressure control valve which, in a separating column, is intended to maintain a specific predeterminable pressure. The valve has a valve seat (12) with an outlet channel opening (18) located in its center and a valve body (13) that cooperates with the valve seat. The valve body (13) can be moved with the aid of a piezo transducer, actively in the opening direction and, while being monitored, actively in the closing direction. The opposed faces of the valve seat (12) and the valve body (13) are so shaped that an annular gap (16) that widens radially towards the outside starting from the opening (18) of the outlet channel is produced. When the valve is in the closed position, this results in the formation of a narrow sealing zone directly at the edge of the opening of the outlet channel.

Abstract: Un procédé et un appareil servent à traiter des matériaux de verrerie dans des conditions d'oxydation et à traiter ou fondre des matériaux, tels que des déchets dangereux ou toxiques, dans des conditions de réduction. En tant qu'appareil de fabrication de verre, l'invention comprend un réacteur de fusion à cyclone qui forme du verre fondu liquide et un préchauffeur de combustion qui reçoit les matériaux de fabrication du verre et qui brûle le combustible et l'oxydant qu'ils contiennent afin de chauffer les fournées de verre jusqu'à une température au moins égale à la température de fusion des fournées de verre. Le préchauffeur de combustion comprend un orifice de sortie relié au réacteur de fusion du verre et au moins un orifice d'admission des matériaux oxydants qui permettent de créer une zone de mélange intime dans le préchauffeur de combustion. On peut apporter de la chaleur supplémentaire en introduisant un gaz de transfert chauffé dans le préchauffeur de combustion et un gazéificateur du combustible peut produire un combustible gazeux avant que celui-ci ne soit injecté dans le préchauffeur de combustion. Afin de traiter des matériaux dans des conditions de réduction, le réacteur de fusion à cyclone est relié à une chambre de préchauffage/réduction et du gaz réducteur préchauffé est introduit dans la chambre de réduction de façon à créer une zone de mélange intime dans la chambre de réduction.

<??>To improve the key in terms of stability in its incision region (5) and also with a view to an even larger number of possibilities for accommodating its incisions (6), whilst at the same time preserving its profile region (2) allowing variable profiled grooves to be formed, the incision region (5) has an essentially circular-cylindrical shape and is made wider than the profile region (2) of the key. Advantageously, at the same time, the height (H) of the profile region (2) exceeds that (h) of the incision region (5), as seen in the radial direction.
