Abstract: A plate glass repair tool has two casing members rotatably connected to one another, one of the two casing members having a screw thread defining a helical groove. The screw thread has a pitch varying in a direction from a distal end to an opposite end of the tool, an angle of inclination of the screw thread with respect to a transverse plane increasing continuously in the direction from the one end to the opposite end, a camming element extending from the other of the two casing members into the helical groove. The two casing members each comprise a cylindrical body, the cylindrical body of the other of the two casing members being disposed about the cylindrical body of the one of the two casing members.

Abstract: The invention concerns a polishing apparatus (1), which has a very short handy and comfortable to handle construction with a very short length L. In order to reduce energy loss a direct vertical shaft (3) is used, which shaft (3) eccentrically drives the rotational head part (9). The special three legged support of the polishing apparatus (1) consists of the sanding or polishing disc (10) and two separately placed from each other adjustable support legs (11, 12). In this way flat and bent surfaces, such as vehicle panes, can be polished accurately and efficiently.

Abstract: The invention relates to a high gloss car wash-resistant coating composition comprising an epoxy-functional binder and a cross-linker reactive with the epoxy groups of the binder and a method to prepare such a car wash-resistant coating. The invention further relates to the use of said coating composition, as a pigment-free top coat or a clear coat, in the finishing and refinishing of articles, for example motorcycles, cars, trains, buses, trucks, and aeroplanes. The coating composition after curing forms a coating having an initial gloss of at least 81 GU and a loss of gloss (LoG) of less than 0.25, the loss of gloss being determined by the formula (I) LoG =(1?e(A/X)/(1+eK)+(1?eD*?Tg)??(I) wherein K=B*(Tgonset?C) In formula I A=?8.03, B=?0.21, C=328 and D=?0.00304.
