Abstract: A disconnect has a housing defining a cavity, a busbar fixed in the housing and extending through the cavity, a piston movable in the cavity past the piston for breaking a piece out of the busbar, and a plurality of metallic filter elements exposed in the cavity below the busbar and electrically connecting with the piece on activation of the disconnect. An igniter displaces the piston in the cavity into engagement with and past the busbar so as to break the piece out of busbar and displace it past the filter elements such that an arc created by breaking out the piece is drawn by the piece away from the busbar and energy of the arc heats and is dissipated in the filter elements.

Abstract: The invention relates to a current breaker in which a busbar (18) passes through a cavity (25) in which a piston (14) can be moved. By moving the piston (14), a circuit board (19) is broken out of the busbar (18), thus interrupting the current flow. The current breaker has at least one metal filter element (16) which, according to the invention, extends up to the cavity (25). This ensures that the disconnected circuit board (19) touches the at least one filter element (16) during tripping. After the circuit board (19) is separated from the busbar (18), an electric arc is formed which, due to the filter element (16) being touched by the circuit board (19), switches over to the metal filter element (16) when the circuit board (19) continues to move, as a result of which the energy from the system inductance is converted into heat loss in the filter element (16). When suitably designed, there is only a moderate increase in pressure in the current breaker and thus practically no external effect.

Abstract: A composite profile for windows, fixed glazing, façades, doors or glass roofs. A metal profile is produced by shaping, in particular by roll-forming, from a sheet metal material and that has a profile cross section that forms a groove and a web, the web being formed by profile portions that are on top of one another at least in portions and transition into profile portions that define the groove. The composite profile further comprises an integral or multi-part insulating profile received in the groove of the metal profile in portions and is non-positively and/or positively connected to the metal profile. The insulating profile and/or a further profile received in the groove of the metal profile engages/engage in pockets of the metal profile that are open towards the groove and are arranged on either side of the web.

Abstract: A method for the production of a cold-rolled profile having at least one thickened profile edge made of a metal strip is provided. For this purpose the metal strip is guided through at least one clamping nip formed by at least one guide roll and at least one lateral edging roll, wherein the roll axis of the guide roll is disposed parallel to the web level of the metal strip, while the roll axis of the edging roll is disposed transverse to the roll axis of the guide roll, and is lined up at an angle to the strip level such that in addition to the upsetting force exerted by the edging roll onto the strip edge a clamping force is also applied that acts on the side of the metal strip facing away from the guide roll. The edging roll may be configured in steps, and surrounds the web edge at least on the side of the metal strip facing away from the guide roll.

Abstract: A method for the manufacture of a profile having a cross-section of different thicknesses from a flat metal strip is provided. In this process, a roller pair produces at least one first recess on at least one side of the metal strip, the recess being widened by following roller pairs with incrementally enlarged recess width to form a region with a reduced material thickness. The aim of the invention is to improve the production process, in particular to avoid the formation of undulations during the production of the profile. For this purpose, the invention provides that regions of the flat metal strip which are arranged adjacent to the at least one recess are bent up before and/or during an engagement of a roller pair.

Abstract: The invention relates to a method for the manufacture a profile with a cross-section of different thicknesses from a flat metal strip (7) by means of roll-profiling. In this process, a roller pair (2.1, 2.2) produces at least one first recess on at least one side of the metal strip (7), said recess being widened by following roller pairs with incrementally enlarged recess width to form a region with a reduced material thickness (12.1, 12.2). The aim of the invention is to improve the production process, in particular to avoid the formation of undulations during the production of the profile. For this purpose, the invention provides that regions of the flat metal strip (7) which are arranged adjacent to the at least one recess (9.1, 9.2) are bent up before and/or during an engagement of a roller pair (2.1, 2.2).

Abstract: A pyrotechnic initiator, for example, for inflatable safety air bags of automotive vehicles can include an electrically energizable initiator bridge and a reactive layer on the initiator bridge for liberation of energy upon electrical energization of the bridge. The reactive layer can consist of a combustible metal or a metal capable of liberating energy by alloying with a metal of the bridge.
