Abstract: A waterstop joint includes a sealing strip made of an elastomer or a rubber like material, two bulged portions, each bulged portion extending along a different one of said two peripheries of the sealing strip, two fixation strips, each fixation strip extending from a different one of said two bulged portions, and extending in the same plane as the sealing strip, and a multitude of injection tubes for injecting a curing liquid, such as epoxy resin. One outer end of each of said injection tubes is mounted to, or in the vicinity of, one of the steel strips. The outer end of each of the injection tubes is mounted to, or immediately adjacent to, one of said two bulged portions.

Abstract: A low-pressure tubular system, for instance a vacuum tube train transportation system, comprising: a multitude of interconnected tube sections having a longitudinal axis; wherein each of the tube sections comprise a central part and two outer end parts; wherein the tubular system is configured to maintain a low-pressure environment within the connected tube sections; wherein the system further comprises a multitude of expansion joints connecting the tube sections; wherein each of the expansion joints comprises a sleeve made of a flexible sheet material and comprising a ring shaped endless central part and two ring shaped endless outer end parts; and wherein each of the outer end parts of the expansion joints are arranged to extend coaxial with an adjacent tube section and surround and sealingly engage the outer end part of said adjacent tube section.

Abstract: A method for producing an automobile column is disclosed. The automobile column has a region of a first type and a region of a second type which have mutually different strengths. A transition region having a width of less than 50 mm is formed between the two regions. The automobile column has in the region of the first type a bainitic structure and in the region of the second type a martensitic structure.
