Abstract: In a motor-vehicle drive train containing a differential, which has an differential input part and two differential output parts, a friction clutch with a limited transmittable torque is arranged between two of the differential parts, so that, with a small predetermined difference in torque between the two coupled differential parts, said friction clutch can slip to accommodate torque shocks. A temperature-dependent adjusting means is provided, which reduces the clutch engagement pressure with increasing clutch temperature.

Abstract: In an arrangement of a running roller on a coupling journal of a coupling half of a moveable shaft coupling, a radial rolling bearing, the inner ring of which is connected to the coupling journal by a ball joint, is inserted into the running roller. In order to maintain an additional degree of freedom for the relative movements of the coupling journal in relation to the complementary coupling half in the directions perpendicular to the central axis of the latter, either the running face of the running roller is configured cylindrically or the rolling bearing is configured as a loose bearing.

Abstract: The following components can be fitted alternatively to the front of a photographic functional unit, which is designed for recording photographic images on a photographic film (201) which is disposed therein in a light-tight manner:

Abstract: The invention relates to a method and device for the electrochemical treatment of electrically mutually insulated, electrically conductive areas on an item to be treated by means of a treatment liquid. Insulated, for example etched structures on circuit boards cannot be treated electrochemically with known methods since there exists no electrical connection to the bath current source from individual areas. According to the invention, this connection is produced by brushes which touch the structured surfaces to be treated with their electrically conductive and thin fibres. A large number of brushes which are arranged transversely to the direction of transportation take care of the fact that all the electrically conductive areas on the item to be treated which are arranged in an insulated manner from one another are contacted electrically at least one after another and that the achieved contact time is sufficiently long.

Abstract: A process and apparatus are disclosed for controlling the flow of operations in electroplating plants with horizontal throughflow in which the parts to be electroplated, in particular plate-shaped parts, pass through the plant in succession and are electroplated by means of currents applied by anodes. In order to prevent undesirable, increased precipitation on the front faces or edges of parts to be electroplated which follow each other at undesirable distances apart, or at least to reduce this precipitation to an acceptable level, the position of the parts which pass through the plant in succession and/or the distances between these parts are detected and the application of the electroplating currents is controlled as a function of these positions and/or distances by switching the anodes on and off, in such a manner that the flux density is approximately the same in all regions of the parts.
