Abstract: The aim of the invention is to provide a switching device (1) based on a uniform control tile, which is easy to produce and assemble, ensuring good electric insulation properties. To achieve this, the device comprises an adapter (12) with second contact means (13), arranged to form a connection between first contact means (7, 8) and a conductor (10) that is to be connected. Said adapter and second contact means have insulating isolating elements (18, 18a, 18b, 18c), at least bordering several sides, for defined creepage distances and clearances.

Abstract: A solar insolation concentrator fabricated from a rigid lightweight (slab-like substrate and a plurality of reflectors. Inclined surfaces are formed in the face surface of the substrate, such as by impressing a heated plate portion of a fabrication tool into the substrate material. The fabrication tool is then used to position the reflectors as they are adhered to the inclined surfaces to assure that the reflectors are aligned with respect to a common focal point. An embodiment of the solar insolation concentrator comprising a plurality of identical square flat back-silvered glass mirrors mounted within recesses within a block of high density cellular polystyrene and a tool and process used to fabricate this concentrator are disclosed. The solar insolation concentrator is also suited for use as a reflector of electromagnetic radiation having wavelengths outside the solar energy spectrum.

Abstract: The present invention relates to an arrangement for the vibration-isolating mounting of an electric motor (2) on a support part (6) via an essentially disk-shaped support element (12). The support element (12) has a motor-holding section (24) for connection to the electric motor (2) and a support-holding section (26) for connection to the support part (6), and the two holding sections (24, 26) are connected via elastic, web-like connecting pieces (28). The connecting pieces (28) are designed such that the two holding sections (24, 26) are elastically movable relative to each other three-dimensionally in all directions in space, specifically axially, radially and tangentially, over a certain movement play. The support element (12) has integrated stop means for the three-dimensional limiting of the elastic relative movements of the holding sections (24, 26) and/or an additional mass (110) to influence the vibration behavior.

Abstract: In accordance with the teachings of the present invention, a machine tool assembly is easily reconfigurable to perform single or multiple machining processes on a workpiece so that this machine has exactly the functionality required to perform a given set of machining tasks. The invention allows rapid changes in the machine structure and rapid conversion of the machine by relocating its basic building blocks. The assembly secures a raw workpiece to a table and includes support units that carry at least one single-axis spindle unit. The spindle units are easily attached to one of the support units and are easily movable thereon to perform machining processes from various positions and orientations relative the workpiece. A cutting tool, or other machining tool, is secured to each spindle, which is computer controlled to rotate the tool and stroke it linearly along its axis of rotation. The support units are reconfigurable and can be easily relocated to different positions and orientations about the workpiece.

Abstract: A method of machining a wheel hub and brake component in which the braking friction surface is machined together with the hub bearing journal and seat while the hub and braking component are mounted to a single work holding tool thus enabling both surfaces to be machined relative to one another with close tolerances. In the case of a two-piece wheel hub and rotor assembly, the rotor is mounted to the hub in a manner which establishes the relative position of the rotor relative to the hub prior to machining the hub and rotor.
