The invention relates to a low voltage switchgear with a bimetallic actuator, especially to a motor safety switch. The aim of the invention is to improve such a low voltage switchgear so that the fabrication and assembly tolerances are widely compensated for. To this end, the two-part (21, 22) housing (2) of the switchgear (1) is provided with an opening (23), that is closed with a protective cover (24). By way of said opening (23), the bimetallic component (51) and the jack system are accessible for the purpose of measurement and a bridge system (52) of the bimetallic actuator (5) that is calibrated on the basis of the measured values can be mounted therethrough.

Arrangement for establishing and/or breaking a connection between a plug and a complementary mating plug, wherein a lever which can be pivoted about an axis is arranged on the plug. The connection between the plug and the mating plug can be broken when the lever is pivoted into a disconnection position and/or can be established when the lever is pivoted into a connection position. The plug is, in particular, a switch module, for example a tripping module for a mating plug which is in the form of a circuit breaker.

Clothing ring (27) for an opening roller (21) of an open-end spinning device (1), comprising teeth (38) which are formed by at least one groove (39) incorporated in the peripheral face of a basic body (45) and running in the peripheral direction, and a plurality of indents (40) arranged substantially in the axial direction. An axial separation spacing (t) of the teeth (38) is predetermined by the groove (39) and is significantly smaller than the height (H) of the teeth (38). The teeth (38) have tooth flanks (42) which are continuously concavely curved into the groove (39).

An axial bearing for a high speed open-end spinning rotor mounted without axial thrust in a support disc bearing arrangement has a static magnetic bearing component secured in a bearing housing with at least two axially polarized permanent magnet rings limited by pole discs, and a dynamic magnetic bearing component having ferromagnetic webs on the rotor shaft at the spacing of the pole discs. The static magnetic bearing component (27) is arranged inside a plastic bearing bush (30) and secured by a plastic closing lid (31). The front side of the closing lid (31) has a stop journal (50) forming an axial emergency operation bearing and the rear side has a conically widened fastening lug (51) which is elastically deformed as installed.

A switching device for direct-current applications includes a housing having a first wall and a second wall, a plurality of receiving areas for respective mutually substantially parallel current paths disposed in the housing. Each of the current paths has a respective stationary switching contact element and a respective movable switching contact element, the movable switching element being actuatable into a closed position and into an open position so as to form a respective air break, the respective movable switching contact elements being actuatable simultaneously. The switching device includes a plurality of arc-quenching devices associated with the current paths and disposed next to each other, and at least one magnet. The at least one magnet is configured to generate a magnetic field so as to generate a deflection force on the arcs so as to deflect the respective arcs toward at least one of the respective arc-quenching devices.

An open-end spinning device comprises a spinning rotor (21) rotating in a rotor housing with a spinning insert (24) supported rotatably with respect to the spinning rotor (21) coaxially to the rotor axis (33). The spinning insert (24) can be caused to rotate as a function of the rotary motion of the spinning rotor (21) via a contactless entrainment of the spinning insert (24) by means of permanent magnets (32) attached to the spinning insert (24). In this manner a simple and reliable entrainment and an automatic adjusting of the rotational speed of the spinning insert (24) in the spinning rotor (21) are achieved.

An open-end spinning device has a spinning rotor (3) supported by its rotor shaft (4) in the bearing nip of a support-disk bearing (5) and positioned by a magnetic thrust bearing (18). The magnetic thrust bearing (18) comprises a stationary bearing component (41) with permanent-magnet rings (42, 43) which are enclosed by pole disks (44, 45, 46) and a replaceably arranged bearing component formed of ferromagnetic annular attachments (32, 33, 34) arranged on the rotor shaft (4) which rotate with the spinning rotor. The rotor shaft (4) comprises on one end a bearing area (35) with offset diameter and with at least three ferromagnetic annular elements (32, 33, 34) arranged at the spacing of the pole disks (44, 45, 46), with the ferromagnetic annular elements being optimized as regards their design and arrangement.
