The striker tool is for loosening seized bolts and nuts, and conversely for securing them. The tool has a shaft (2,7) comprised of tubular, telescopically fitting sections (2,7), the facing ends of which have coaxially connected plates (4,7) joined by two diametrically opposed pins (5). - Between the plates is a striker arm (9) which can rotate around the shaft (2,7), causing force to the applied ...

In the removal of polishing or machining lines and similar surface unevenless in materials, laser radiation is applied for a limited time to achieve material redistribution. A Q pulsed NdYAG laser is pref. used to irradiate to a depth of not more than 1 micron for a time of 1010-100 ns. The laser energy is close to the threshold for effect on the material and pref. less than 10 times this threshol...
