Abstract: A medical suspension system (10) includes a ceiling plate (30) configured for mounting to a support structure (16). The ceiling plate supports a device (12), such as a lighthead or video monitor, which is mounted to the ceiling plate via an articulated arm (50) and a spindle (40), which is centrally mounted to the ceiling plate. A second device (14) is mounted to the ceiling plate, not through the spindle (40), in the conventional manner, but via an adapter plate (62), which is mounted directly to the ceiling plate. This increases the number of devices which are readily carried by the support structure without extending the spindle length which conventionally occurs when additional hubs are added to the main spindle.

Abstract: A medical suspension system (10) includes a ceiling plate (30) configured for mounting to a support structure (16). The ceiling plate supports a device (12), such as a lighthead or video monitor, which is mounted to the ceiling plate via an articulated arm (50) and a spindle (40), which is centrally mounted to the ceiling plate. A second device (14) is mounted to the ceiling plate, not through the spindle (40), in the conventional manner, but via an adapter plate (62), which is mounted directly to the ceiling plate. This increases the number of devices which are readily carried by the support structure without extending the spindle length which conventionally occurs when additional hubs are added to the main spindle.

Abstract: An electrically assisted, power steering system for motor vehicles having an input shaft (6) connected to a pinion shaft (2) by a torsionally elastic member (5) is supported in a steering housing (1) by a rolling bearing. The rolling bearing is formed as an elastic, flexible roller bearing (13), whose cylinder rollers (13.5, 13.6) have at least at one peripheral position an elastically deformable cylinder roller (13.6), having a diameter that is slightly greater than a diameter of the other cylinder rollers (13.5). In this way, an exact guidance of the input shaft (6) is achieved, so that the applied steering torque can be used accurately by an evaluation unit (15) for controlling the servo motor (7).

Abstract: The warning tone transmitter (10) according to the invention has a piezoelectric horn element (12) with two input connectors (29, 30) for the application of the supply voltage at a determined frequency and has a circuit arrangement (14) fed from the current supply, which generates the supply voltage. In order to be able to receive confirmation that the horn signal is actually generated by the warning tone transmitter (10) and in order to be able more easily to calibrate the warning tone transmitter (10) such that it is driven at its resonant frequency the piezoelectric horn element (12) has an additional output connector (34), which, when the horn element (12) is fed with the supply voltage, generates an answering signal taken to the circuit arrangement (14) if the piezoelement is actually oscillating. The magnitude of the answering signal is a value for the sound volume of the warning tone transmitter (10).
