    Abstract: An electric machine includes a conductor structure having at least one metallic conductor element made from at least one of aluminum, copper, and silver having a monocrystalline or columnar crystal structure. The conductor structure may be formed from a plurality of individual flat conductor elements integrally bonded together by welding or soldering to form a winding. The metallic conductor element may be cut from an aluminum, copper, or silver bar having a monocrystalline or columnar crystal structure. A wafer having a plurality of conductor elements may be cut from a bar with the conductor elements separated from the wafer.

    Abstract: A system for connecting a wheel rim to a hub flange of a motor vehicle, having a fastener such a threaded nut or bolt, and a tool which engages the fastener in a positive-locking manner in order to tighten or release the fastener. To provide improved protection against theft of wheel rims and tires, the fastener has an annular groove extending axially from an end surface of the fastener, the groove having an annular base and inner and outer sidewalls shaped to form an undercut wider than an opening of the groove, a recess extending axially below the base for receiving a projection of a complementally-shaped key on the tool to allow rotation of the fastener. The undercut prevents an unauthorized person using a mold-making material, from being able to make an imprint of the groove and producing a tool therefrom to release the fastener.

    Abstract: The present disclosure relates to an apparatus for removing industrial powder from a shaped body manufactured generatively using the industrial powder. The apparatus includes at least one container for holding the shaped body having a vertically adjustable construction platform, a vibrating screen, a tilting device for tilting the container, and at least one catching unit adjoining a transfer end of the vibrating screen for catching the shaped body. In one form, the vibrating screen, tilting device, and catching unit are arranged within a housing. In another form, the vibrating screen and catching unit are arranged within the housing and the tilting device is at least partially arranged in the housing. At least one opening in the housing is closed in an airtight manner by a glove such that a user can use the glove to grasp the shaped body caught by the catching unit.
