Abstract: A rear-view mirror for a motor vehicle. The mirror housing, which is provided with the mirror body, is pivotable about an upper transverse axis into two positions (normal position and anti-glare position). In order to reduce the sensitivity of the mirror to vibrations, the housing has a supporting surface associated therewith, at least for the two above-mentioned positions. The supporting surface is curved in conformity with the pivot radius determined by the transverse axis. The housing and the holder, which is used for mounting the housing, preferably have curved surfaces which correspond to one another and via which these component parts may be mutually supported.

The two end positions of the slide valve alternately connect the metering chambers to the inlet or outlet. Transfer passages are disposed on the periphery of the slide valve for selective connection of connecting passages to the inlet, the outlet, and the metering chambers. A transverse connection of the slide valve connects a central control channel thereof to the inlet via a first one of the transfer passages in either of the end positions of the slide valve. Each end of the latter is associated with a hydraulic control chamber into which the control channel opens. Relief passages connect the control chambers to the outlet.

Abstract: A ring-shaped arrangement of individual work locations. Tables which are preferably trapezoidal are arranged in a ring, in the middle of which is disposed a region which is free of table tops, and in which can be disposed common supply lines or the like. The individual work locations, which are arranged around the central region, are respectively separated from an adjacent table by a vertical partition in which is disposed a material-transfer opening. The supply of material to the individual work locations can be effected from supply bins disposed on a shelf supported above the ring-shaped table top on the upper edges of the radially directed partitions. If it is a question of small parts, the latter can be transferred to the work location via conveying tubes, which lead from the supply bins on the shelf to the table top of the individual work locations.
