Abstract: The invention relates to a radiator (10), especially for vehicles, radiator comprising upwardly extending headers (11). Said headers (11) are fluidically interconnected in the longitudinal direction by means of parallel cooling pipes (12). Corrugated ribs (13) are arranged between the cooling pipes (12), the ridge lines (14) thereof extending in the direction of the width (B) of the radiator (10) and lying respectively alternately on both sides of a cooling pipe (12). The inventive radiator is also provided with a lateral metal plate (40) which extends parallel to the cooling pipes (12), on the outside between the headers (11), the width (b) of said plate corresponding essentially to the width (B) of the corrugated ribs (13). According to the invention, the material of the at least one lateral metal plate (40) is weaker in the regions adjacent to the headers (11).

Abstract: Molds (1) with annular mold parts (2, 3) divided by at least one plane of division (E—E) and forming a plurality of cavities (8) disposed at least substantially radially to a centrifugation axis (A—A), serve for the production of precision castings by centrifugal casting, especially of parts made of materials containing titanium for internal combustion engines, the molds (1) and a casting system being contained in a closed chamber. To automate production, at least one mold part (2, 3) is made to rotate in its own rotational guide, and two mold parts (2, 3) together with the corresponding rotational guides are brought to a closed position for the casting and solidification and to an open position for the removal of the precision castings. When cast, the precision castings are preferably joined together at their radially inward pointing ends by a circumferential ring of the solidified metal and thus a circle of castings can be removed from the opened mold by a manipulating system.

Abstract: A sealed evacuatable crucible (1) for inductive melting of metals or other electrically conductive materials, including a plurality of palisades (2,2', . . . ) which are arranged parallel to one another, and for enclosing the melt and forming the crucible wall, and having a crucible base part (3) which carries the palisades (2,2', . . . ), and having an induction coil (18) which is wound around the palisades (2,2', . . .
