Abstract: The invention relates to a permanent mold plate having a plurality of fastening points (3) on the rear side (2) thereof for fastening purposes, and cooling ducts (5) which are adjacent to the fastening points (3) and are in the form of depressions that are located within the rear side (2) and are open towards the rear side (2). From the perspective of a fastening point (3) towards the casting side (4) of the mold plate (1) opposite the rear side (2), at least one cooling duct (5) extends all the way to a point located below the fastening point (3).

Abstract: The invention relates to a contact tip (1) for arc welding with at least one channel (2) passing through the contact tip (1) for receiving a welding wire (3), the channel (2) having a non-round stellate, multi-lobular cross-section with convexly rounded sides.

From the perspective of a fastening point (3) towards the casting side (4) of the mold plate (1) opposite the rear side (2), at least one cooling duct (5) extends all the way to a point located below the fastening point (3).

Abstract: A device for transporting a medium includes at least one channel which extends in an axial direction and through which the medium is guided. The channel is enclosed by an electrically conductive inner envelope that is connected to a first potential equalization conductor. An electrically conductive outer envelope is provided between the channel and an electrically conductive outer casing and is connected to an electrically conductive second potential equalization conductor. Arranged between the channel and the outer envelope is an electrically insulating intermediate layer which is produced from heat-insulating material.

Abstract: A cooling element for a melting furnace includes at least one cooling pipe for passing through a coolant, and a support element to which the at least one cooling pipe is fastened. At least one cove plate is welded to the at least one cooling pipe. The at least one cooling pipe has at least one bead which extends in the longitudinal direction of the at least one cooling pipe and to which the at least one cover plate is welded.

Abstract: A connecting piece includes a stamped metal sheet for conductively connecting poles of two batteries or battery cells, which connecting piece has a main body with a recess, wherein at least one insert element is arranged in the inner region of at least one recess. Either the insert elements have a groove on the circumferential face thereof, said groove running at least in regions of the circumference, or the main body has a groove on the inner face of the at least one recess therein, said groove running at least in regions of the circumference. The respectively corresponding component has a projection which is generated by material displacement when the two or one of the two components are/is pressed and which engages in the groove in an interlocking manner, so that the main body and each insert element are connected to one another, in an interlocking manner at least in regions, along the circumference of the insert element.

Abstract: A boat launch for the pillars of offshore installations includes fender pipes extending substantially perpendicularly to sea level and a ladder being positioned closer to the pillars than the fender pipes. The fender pipes have an inner pipe consisting of steel that is not resistant to seawater and an outer pipe consisting of a seawater resistant metal alloy.

Abstract: A continuous casting mold for casting a strand of metal includes a sidewall having an inner circumference to define a mold cavity which has a pouring opening for liquid metal and an outlet opening for a cast strand. The mold cavity has a cross section sized to correspond to a basic shape of the cast strand. The sidewall is provided with a profiling in the form of a corrugation that extends in a casting direction and forms grooves extending in substantial parallel relationship from the pouring opening to the outlet opening of the mold cavity. A ratio of the inner circumference of the mold cavity to a width of each of the grooves is greater than 30, and the width of the groove is in the range of 1.5 mm to 30 mm.
