摘要： A bumper beam is roll formed so that it gets a closed cross section with, along the length, constant cross section having at least two closed chambers (15, 16) separated by an essentially horizontal partition wall (14). Each chamber has a side (19), which is turned away from the vehicle, with at least one longitudinal concave portion (20, 21; 22, 23) extending along the entire length and one side (24), which is facing the vehicle, with at least one longitudinal convex portion (25, 26; 27, 28) extending along the entire length. After the roll forming, some portions (32) of the cross section are pressed together vertically or horizontally in order to adapt the deformation properties.

摘要： In an apparatus for disposing of wastewater in subsurface soil, corrosion-resistant wire-mesh is formed by profile-rolling into a conduit-arch skeletal framework with open floor and is covered with non-woven geofabric. This conduit, set in excavated trenches to form a leach field and is buried with permeable soil cover, allows dispersal of wastewater throughout the trenches without distribution pipe or crushed stone, and allows substantial evaporation from the trenches and substantial air infiltration into the trenches to encourage aerobic degradation of organics and ammonium. The wire-mesh is derived from easily available coils sold for wire-mesh fencing.

摘要： A tip shaping apparatus presses electrode tips against a shaping roller thereof held by a rotationally driven holder in such a manner as to bring tip sections of the tips close to each other, thereby shaping the tip sections into reusable condition. The tip shaping apparatus includes deburring sections located in such positions as to confront burrs that are formed during shaping in such a manner as to project from outer circumferences of root sections proximate the tip sections of the electrode tips in a direction perpendicular to the axes of the electrode tips, at ejection of the electrode tips from the apparatus. Each of the deburring sections is located proximate an outer circumferential plane of the root section of each of the electrode tips undergoing shaping so as to abut against and cut off or bend the burrs in such a manner as to suppress the projecting height of the burrs when the electrode tips are ejected from the tip shaping apparatus.
