  • Patent number: 11383292
    Abstract: A mould plate includes a casting side and a rear side facing away from the casting side and having a cooling channel configured to open towards the rear side and having a cooling face opposite the casting side. An insert is arranged in the cooling channel to form a cooling gap between an inner face of the insert and the cooling face. A fastening bolt connects the insert to a fastening point in the cooling face, wherein the cooling gap extends, viewed from the fastening point towards the casting side, to an area below the fastening point.

  • Patent number: 6063998
    Abstract: A cable head, in which ends of cable cores, made of a plurality of individual stranded conductors, are inserted into the bore holes of a cable lug. The cable cores are fixed in position in the bore holes by radial pressing and deformation of the bore holes. The bore holes are located on divided circles which are concentric relative to each other, the bore holes on the inner divided circle being staggered with respect to the bore holes on the outer divided circle. Cooling-water grooves between the bore holes located on the outer divided circle extend, with a depth, into the proximity of the bore holes arranged on the inner divided circle. They are connected to a central cooling-water channel in the cable head.
