摘要:
The invention relates to a tool for machining sliding surfaces of a bearing shell (30), comprising a rotary drive for driving a drilling spindle (20) that can be rotated about a rotational axis and at least one first cutting cartridge that is mounted on the drilling spindle (20) in order to cut the bearing shell (30) to a certain wall thickness by rotating the drilling spindle (20). The tool is characterised in that the first cutting cartridge can be adjusted by an adjustment means in a direction of adjustment that has a component in the radial direction of the drilling spindle, while the drilling spindle (20) is rotated by the rotary drive. The invention further relates to a bearing shell (30) comprising a deliberately structured sliding surface (31) and to a method for producing a bearing shell (30) comprising a deliberately structured sliding surface (31).

A method and apparatus are provided for implementing very high density signal probing of a printed circuit board having a pad pattern connected to signals of interest. A metal plate includes a plurality of through holes arranged in a predefined pattern that corresponds to the pad pattern on the printed circuit board. At least one signal module is inserted within a selected one of the through holes of the metal plate. Each signal module defines a coaxial connector for electrical mating engagement with a coaxial cable connector and has an embedded resistor. At least one power/ground module is inserted within a selected one of the through holes. Each power/ground module contains a high dielectric constant material between an outer conductor and a center conductor defining a capacitor. The capacitor provides a low impedance path between the metal plate and a power or ground pad of the printed circuit board.

A slide bearing has a layered structure which is substantially uniform over the circumference thereof and comprises a base (10), a lead-free slide layer (12) having a thickness which is reduced in edge zones (16) as compared to a central zone between the edge zones (16), and a polymer coating (14) which is thicker in the edge zones (16) as compared to the central zone, so that the surface level of the coating (14) is substantially flat as seen in axial cross-section.

A clothesline system is provided for automatically applying clothespins to articles to be dried once they are placed on a clothesline. The clothesline system comprises first and second pulleys, which are positioned at a spaced apart distance from each other, as well as a main cable, a secondary cable and a plurality of clothespins. The clothespins are capable of being removably attached to the secondary cable, and are movable between an open and closed position for receiving and gripping articles to be dried to the main cable. The clothesline system further comprises a mechanism for automatically opening and closing the clothespins so that they are able to either selectively grip or release the articles to be dried. Finally, the clothesline system comprises a support system for guiding and supporting the main cable such that the main cable is prevented from sagging beyond an acceptable distance within which the clothespins are capable of being attached to the main cable.
