    • A method for non-destructive testing of a weld joint of a bolt welded onto a contact area on a planar sheet metal using the lift ignition method uses directed ultrasonic signals. During the welding operation a weld pool having a modified material structure is formed beneath the contact area in the sheet metal. Ultrasonic signals are transmitted into the sheet metal using a directed and obliquely transmitting ultrasonic transmitter positioned at a coupling-in point A. An ultrasonic receiver is positioned at a coupling-out point B and receives the ultrasonic signals transmitted through the sheet metal at the coupling-out point B, an acoustic path being formed between the coupling-in point A and the coupling-out point B. The acoustic path is positioned so that it passes a center of the contact area in a distance d from this center, d being smaller than the radius of an intact weld pool and bigger than the radius of a non-intact weld pool, and the intensity of the ultrasonic signals transmitted along the acoustic path from the coupling-in point A to the coupling-out point B is detected.
    • 使用提升点火方法焊接在平面金属板上的接触区域上的螺栓的焊接接头的非破坏性测试方法使用定向超声信号。 在焊接操作期间,在金属板的接触区域的下方形成具有改性材料结构的熔池。 使用位于耦合点A的定向和倾斜发射的超声波发射器将超声波信号传输到金属板中。超声波接收器位于耦合输出点B处,并接收在耦合处通过金属板传输的超声波信号 - 出点B,形成在耦合入点A和耦合输出点B之间的声学​​路径。声学路径被定位成使得其穿过距离该中心距离d的接触区域的中心,d 小于完整焊池的半径,并且大于不完整焊池的半径,并且检测沿着从耦合入点A到耦合输出点B的声路径传输的超声波信号的强度 。

    • The present invention relates to a process for the production of a polyurethane foam, comprising the reaction of a polyisocyanate and a polyol in the presence of a blowing agent and of particles. These particles are obtained by reacting carrier particles with a functionalising reagent G, wherein G contains reactive groups G1 by means of which G can be chemically bonded to the surface of the carrier particles, and wherein G additionally contains reactive groups G2 which, under the conditions of the polyurethane foam production, are reactive towards the NCO groups of the polyisocyanate, or towards the OH groups of the polyol, or both, and wherein G1 and G2 may be the same or different. The present invention relates also to a polyurethane foam obtained by this process and to products containing such a polyurethane foam. The present invention relates also to a composition containing a polyol and these particles. The present invention relates also to a composition containing a polyisocyanate and these particles. Both the mentioned compositions can be used to produce a polyurethane foam according to the invention.
