Abstract: The present invention relates to a device for the contact-free inductive transfer of electrical energy from a first, preferably stationary system of a shifting device into a second system of the shifting device, which can be moved relative to the first system, comprising a magnetic circuit of a primary core, which is assigned to the first system and onto which a primary coil is wound, and a secondary core, which is assigned to the second system and onto which a secondary coil is wound. The secondary core is arranged so as to be capable of being shifted relative to the primary core along a shifting path, which preferably runs parallel to a shifting path of the shifting device. The primary core extends at least along the entire length of the shifting path. According to the invention, provision is made for the primary core to comprise at least one primary core gap, which is embodied along the entire longitudinal extension of the primary core.

Abstract: A workpiece positioning arrangement comprises a positioning device for positioning a workpiece as well as a decoupling device for the decoupled storage of the positioning device, wherein the decoupling device comprises a carrier element, on which the positioning device is arranged, and a base element, on which the carrier element is supported. For decoupling the dynamic reaction forces of the positioning device on the base element, the carrier element is supported on the base element so as to move freely at least in a certain range, preferably essentially free of counterforces, in a sliding manner.

Abstract: The invention relates to a heat-conducting element (10) for arrangement between movable components (B1, B2) in a vacuum, comprising rolling elements (11), which are guided between two running surfaces (12, 13) that can be moved linearly relative to each other, and further comprising at least one supporting element (14), which is mounted so as to spring back elastically against one of the running surfaces (12) and which contacts said running surface (12) in such a manner that a thermal bridge exists between said supporting element (14) and the running surface (12). The invention further relates to an assembly (30) made of two components (B1, B2) which can be moved relative to each other, comprising at least one linear bearing (20) accommodated between said components (B1, B2), and at least one heat-conducting element (10) according to the invention, which is arranged between the components (B1, B2) in an elastically preloaded manner.

Abstract: The protective equipment switch comprises a mechanical switching contact (2) for a conductor (S1-S3), a latchable switch latch (6) for the switching contact (2), an overcurrent sensor (3) associated with the conductor, and an electromechanical undervoltage relay (7) whose exciting voltage is derived from the conductor voltage and which in its excited state latches the switch latch (6). In the case of overcurrent, the overcurrent sensor (3) causes the separation of the undervoltage relay (7) from its exciting voltage which also drops in the case of undervoltage. Thus both in the case of overcurrent and in the case of undervoltage, unlatching of the switch latch (6) is caused by the same component, namely by the undervoltage relay (7). Preferably the overcurrent sensor (3) is formed by the combination of a current transformer signal with an electronic circuit which itself is preferably an integrated circuit.

Abstract: The breaker mechanism (6) has a position to either side of a zero position and is distinguished in that it has a minimum number of few parts, and that it can be assembled from only one direction. This ensures a trip-free mechanism. Conversely, switching on is impossible when the breaker mechanism (6) is unlatched. The breaker mechanism (6) has an intermediate piece (15) that is assigned an alternating function in reference to the two positions. Together with a rotary handle (12), it forms a toggle lever joint with two effective ends.
