20090251871 | RETAINING FACILITY FOR PRINTED CIRCUIT BOARDS ON CURVED SURFACES - A retaining facility for clearance-free fixing of a printed circuit board onto a one-dimensional curved surface is provided. In the direction of curvature of the one-dimensional curved surface, a tensile or compressive force acts on the printed circuit board or on at least one first connection device connected to the latter, with the printed circuit board being bent and pressed onto the curved surface. In this way the printed circuit board is held solidly and with little vibration on the surface even when acted on by centrifugal forces. | 10-08-2009 |
20090257206 | HOLDING APPARATUS - The invention specifies a holding apparatus comprising a support element and a circuit board. A trench for receiving the circuit board is embodied in the support element. At least one first clamping element is arranged on one or both longitudinal sides of the circuit board and/or at least one second clamping element is arranged in the trench. As a result, the circuit board received by the trench is fixed in the trench in a clearance-free fashion. | 10-15-2009 |
20110140568 | BRUSH DESIGN FOR SLIP RING CONTACTS - The present embodiments relate to a device for establishing an electrical contact between two device elements moving relative to each other. The device includes a plurality of brushes that may be arranged on one of the device elements and establishes contact on the relative movement of the device elements along a slideway provided on the other device element. The brushes are arranged staggered one behind the other relative to a direction of movement determined by the relative movement. The brush arrangement according to the present embodiments is more robust than conventional arrangements with respect to wear and ageing. | 06-16-2011 |
