Abstract: A laminated glass and an interlayer film for laminated glasses are provided, which have the high performance for mitigating the impact given externally and, particularly in the case of using it as glass for vehicles, and which have the high performance for mitigating the impact when a person's head comes into collision with the glass due to the occurrence of a personal accident. Also provided is a laminated glass, wherein at least an interlayer film for laminated glasses and a glass sheet are laminated and unified, Head Injury Criteria (HIC) values, measured according to regulations of European Enhanced Vehicle-safety Committee; EEVC/WG 17, being 1,000 or lower.

Abstract: A portable exercise device is provided. The device includes an elastic cord with two ends. Each of the ends of the cord is received into opposite sides of a coupling. A clamp element is provided around a portion of the coupling. The clamp element compresses the coupling around the elastic cord to hold the cord in place inside the coupling. A handle may be provided around the coupling. The handle may be made from a resilient material so that the hand of the user may squeeze it. Additionally, end plugs may be provided for the handle to prevent the handle from slipping off the coupling.

Abstract: Compositions containing water, an organic dicarboxylic acid, a buffering agent and fluorine source and optionally a water miscible organic solvent are capable of removing etching residue.

Abstract: In resistance forge welding, the heat for the welding point is produced by simultaneous action of an electrical current and the force of the electrode as well as the electrical resistance of the materials to be welded in the region of the point of contact of the electrodes. The workpieces generally lie flat on each other and are welded under considerable pressure at individual points by the force of the electrode. The current and the electrode force are supplied via the electrodes.In order to increase the controllability and dynamics of the electrode movement, according to the invention a controllable electromotive drive (13), which has a drive spindle (16) or a toothed rack, is used.
