Abstract: A method and apparatus for defending against airborne assault ammunition. The assault ammunition is located with at least one position-locating device. The flight path of the assault ammunition is iteratively calculated using the determined ballistic coefficient of the assault ammunition. A firing control solution is determined for firing a fragmentation-type defense ammunition, which is fired with a large-caliber weapon, especially one having a caliber of at least 76 mm. A fuse of the defense ammunition is set after the firing and/or the defense ammunition is remotely detonated, and after the firing the defense ammunition is ignited or remotely ignited at an ignition time point TZ. Alternatively, the ignition of the defense ammunition is initiated by a proximity igniter disposed in the defense ammunition.

Abstract: A mold portion of a molding tool for making plastic articles includes a base body defining a cavity surface and having formed therein at least one heating channel, and at least one cooling channel separated from the heating channel and having a cross section which is smaller than a cross section of the heating channel. The cooling channel is positioned hereby closer to the cavity surface than the heat channel and thus is in an area between the heat channel and the cavity surface, thereby defining a cavity-proximal cooling channel and a cavity-distal heat channel. Before the injection process, the cavity surface is heated by the heat channel to a higher temperature than the demolding temperature of the plastic article to be formed. At the end of the injection process, the cavity surface is cooled by the cooling system.
