Abstract: The invention relates to a novel design of hydraulic processing pincers for processing workpieces, with a tool which, in a first tool part, has an axially displaceable tool plunger which, with a first end or with a tool provided there and an opposite work rest, forms a working region or a working gap and can be moved with the first end towards and away from the work rest, and made up of a hydraulic actuating device for applying a force to the tool plunger via a movable pressure-transmitting element, said force moving said tool plunger in the direction of the work rest. The piston and/or the piston rod are/is designed with a cavity in which the tool plunger is accommodated in its initial position at least over part of its length.

Abstract: A rolling bearing for a turbocharger, which has an outer ring with a first rolling element raceway, an inner ring with a second rolling element raceway, and several rolling elements accommodated in rolling element pockets of a rolling element cage. The rolling element cage has a guide surface, which is guided on an inner surface of the outer ring and arranged on a smaller radius than the radius of the first rolling element raceway. The rolling element cage has an extension, which is arranged over the circumference of the rolling element cage and extended annularly in the radial direction, on the side opposite the guide surface.

Abstract: A supply unit including a funnel-shaped container for receiving a quantity of unsorted, or randomly oriented, nuts and bolts, a conveyor that is driven, in a reciprocating manner, along an inwardly tapering interior wall of the container. The upper carrying surface of the conveyor dips into the unsorted nuts and bolts on its downward stroke and picks up some of the nuts and bolts. On its upward stroke, or travel, the conveyor cooperates with the adjacent wall to properly orient the majority of the nuts and bolts. Some of the improperly oriented nuts and bolts may fall off the conveyor during its upward travel. Blasts of air, or mechanical deflectors, cause other improperly oriented nuts and bolts to fall back into the container. A step is formed near the top of the container, and the upward travel of the conveyor term mates above the step. The properly oriented nuts and bolts are transferred away from the container by a transport assembly located in proximity to the step.
