Abstract: The invention relates to a method for installing a profiled sealing section, a profiled edge protection section or similar profiled extruded section formed of an extruded material on a component of a motor vehicle, in which the extruded material (10) is wound off a reel, at least one length section having a predefined length of the extruded material is cut off the extruded material as the profiled sealing section, profiled edge protection section or similar profiled extruded section to be installed, and is installed on the component. Prior to being wound onto the reel, the extruded material (10) is prepared such that the extruded material (10) comprises defect-free usage sections (14) having a predefined usage length (16), between which intermediate sections (18) having a predefined intermediate length (20) are arranged. As part of the installation, the intermediate sections (18) are removed from the extruded material (10) and separated as scrap.

Abstract: A process for preparing grit blasting particles coated with titanium dioxide by sinter-fusing titanium dioxide on the surface of grit blasting particles made of a base material. A mixture of finely divided titanium dioxide and grit blasting particles is passed continuously through the flame in a flame reactor, with the aid of conveying air, wherein the titanium dioxide is sinter-fused on the surface of the grit blasting particles over an average residence time of 0.1 to 5 seconds in a temperature range from 600 to 1200° C. An increase in the adhesive bond between metal framework and a facing material made of plastics in dentures can be achieved when metal framework is grit blasted with a grit blasting agent containing titanium dioxide coated grit blasting particles and then the grit blasted and titanium dioxide coated surface is treated with a silane bonding agent.

Abstract: Disclosed is an optical device with at least one lens and at least one swiveling observation tube, exhibiting the following characteristics: The observation tube comprises a base section fixedly connected to the optical device, and an eyepiece carrier which rolls along an arc of a circle so that swiveling can occur on the base section; a first rotatable deflecting mirror whose rotational axis orthogonally intersects the optical axis of an objective lens of the optical device and which is forcibly rotated by the movement of the eyepiece carrier on the base section; a second rotatable deflecting mirror is arranged in the eyepiece carrier and whose rotational axis orthogonally intersects the optical axis as deflected by the first deflecting mirror and which is forcibly rotated by the movement of the eyepiece carrier on the base section.
