Abstract: Systems and methods for coupling a tag to an item. The methods comprise: dispensing the tag from a tag feeder of a tag applicator; performing first operations by the tag applicator to mechanically move the tag into a nest of the tag applicator; determining if a given criteria is met based on feedback information received from at least one of a user of the tag applicator and a sensor provided with the tag applicator; and performing second operations by the tag applicator to couple the tag to the item, when a determination is made that the given criteria is met.

Abstract: The disclosure proposes an electrical switching device having at least one contact point having at least one drive, which opens the contact point directly and/or via a switching mechanism with a latching point and which drive has an element having a predetermined shape, which element consists of a shape memory alloy, which changes its shape under the influence of an electromagnetic field and, in the process, opens or closes a contact point or double contact point or unlatches a switching mechanism.

Abstract: The invention relates to switching equipment comprising a housing, at least one contact point that has at least one fixed and one mobile contact part and an electromagnetic trip device, comprising a trip coil and a hammer armature. Said equipment is wherein the electromagnetic trip device comprises a snap body consisting of a material with magnetic shape memory properties, which interacts with the hammer armature. According to the invention, when a short-circuit occurs, the snap body is switched between two bi-stable positions by the influence of the magnetic field of the trip coil.

Abstract: The disclosure relates to an electrical installation device, e.g., a circuit-breaker, motor protecting switch, and similar, comprising a housing that is formed from shell-type housing parts, an electromagnetic trigger, a thermal trigger, a breaker mechanism with a latching point, a slide which transmits the movements of the thermal trigger and the magnetic trigger to the breaker mechanism in order to unlatch the same, and a striker that is connected to the armature of the electromagnetic trigger and acts upon a movable contact piece of a contact point in case of a short-circuit so as to open the contact point. The shell-type housing parts, the slide, and the striker are made of plastic. At least the slide is formed from radiation-crosslinked thermoplastic to which an additive has been added as a crosslinking promoter before the radiation process.

Abstract: The invention relates to electrical switches, in particular line-protection circuit breakers or motor protection circuit breakers, with at least one contact point at which an arc occurs during a switching operation. Having a stack of arc-extinguishing plates made up of several extinguishing plates, the extinguishing plates of said stack being held together with a spacing by means of holding elements, the holding elements are made from a thermoplastic, the subsequent assembly of which is radiation cross-linked.

Abstract: A switching device has a housing and at least one contact point, which comprises a fixed contact piece and a moveable contact piece, and having a thermal and magnetic release, which comprises a tripping coil and a tripping armature. The tripping armature comprises at least two operatively connected tripping armature parts. The first tripping armature part is formed from a first material having a magnetic shape memory effect. The second tripping armature part is formed from a bimetallic strip or from a material having a thermal shape memory effect or from a material having a combined thermal and magnetic shape memory effect. The tripping armature, both under the influence of the magnetic field of the tripping coil in the event of a short-circuit current and under the influence of an increase in temperature brought about by overcurrent, can be deformed and, as a result, the contact point can be caused to open.

Abstract: The invention relates to switching equipment comprising a housing, at least one contact point that has a fixed and mobile contact part and an electromagnetic trip device comprising a trip coil and a trip armature. Said equipment is wherein the trip armature is configured from a material with magnetic shape memory properties. According to the invention, when a short-circuit occurs, the trip armature is deformed by the influence of the magnetic field of the trip coil, thus causing the contact point to open.

Abstract: An arc quenching configuration for an electrical switching device has an arcing chamber in which an arc is produced between a stationary contact piece and a moving contact piece during a switching operation. An arc splitter stack is provided and has a number of arc splitter plates and into which the arc is passed via guide rails. At least one plate composed of an insulating material is disposed in or adjacent to the arc splitter stack, an external circumference of the plate does not project beyond the external circumference of the arc splitter plates, and the plate has an internal recess.

Abstract: A method for controlling distortion of a turbine case (“case”) includes measuring a temperature distribution for the case that includes thermal gradients. The method further includes modeling thermal stresses on the case induced by the thermal gradients, calculating an out of roundness index (“index”) resulting from the thermal stresses, and comparing the index with at least one distortion limit to determine whether the case has a satisfactory or an unsatisfactory index. The temperature distribution is controlled for an unsatisfactory index to produce the satisfactory index. A system for controlling distortion of the turbine case includes a thermal measurement system, for measuring the temperature distribution, and a computer configured for modeling the thermal stresses, calculating and comparing the index with the distortion limit, and controlling the temperature distribution for an unsatisfactory index to produce the satisfactory index.

Abstract: An electromagnetic release drive, particularly suitable for a residual current circuit breaker, includes a plunger loaded by a spring in a release direction, a permanent magnet configuration, a coil and a yoke. The coil generates in the yoke a magnetic flux opposed to the permanent magnet configuration when the coil is driven or released such that the spring force overcomes the attraction force of the permanent magnet configuration. The permanent magnet configuration and the pole shoe conducting the magnetic flux to the plunger are associated with the yoke and the plunger such that, in a first position, the plunger is located in the active range of the permanent magnet configuration and of the pole shoe and, in a second position, is located at least partly in the active range of the pole shoe.
