Abstract: A device (1) for machining by turning rotationally symmetrical surfaces (18, 20 or 22) of a workpiece (10), which is clamped and has a rotating drive, including a tool (12) having two cutting edges (16) and (17), each having an approximately helical shape, which are disposed one behind the other in the feed direction of the tool (12) such that after the machining by turning with the first cutting edge (16), a roughing edge, the second cutting edge (17), a finishing edge, comes into engagement.

Abstract: A handle has a grip part rotatably journaled between two end positions and is provided with a sensor which detects one of the end positions.

Abstract: The invention relates to a bracing ply comprising reinforcing elements, which are made of steel cords, for a vehicle pneumatic tire, in particular, for a pneumatic tire used on transporters or light trucks and reinforced pneumatic tires. Said bracing ply is provided with two steel cord plies (bracing plies) which are stacked in a radial direction, whereby the radially inner steel cord ply is wider in the axial direction of the tire than the radially outer steel cord ply. In addition, the individual steel cords of a ply run diagonally with a slope ranging from 18° to 25° with regard to the zenithal plane of the tire. The radially inner and the radially outer steel cord plies have opposed slopes, are comprised of individual filaments with a filament diameter of 0.32 mm, and are provided with a U+T structure (untwisted+twisted), whereby the radial distance between steel cord plies is smaller in the zenithal plane of the tire than in the shoulder areas.

Abstract: In a rotogravure printing press, the two journal bearings of the impression cylinder are each connected to a double acting piston-cylinder unit for lifting and lowering the impression cylinder and are interconnected by a synchronizing shaft which is mounted thereon and is provided with pinions engaging racks fixed with respect to the frame of the press. The synchronizing shaft can be coupled to the journal bearings by at least one spring-biassed multiple disc brake which is released when the impression cylinder executes a wide stroke for the purpose of cylinder replacement and during pressure application of the impression cylinder. The brake is actuatable for engagement at the end of a short stroke when pressure is withdrawn.
