Abstract: In order to further improve a method for joining a multilayer component (10) to another component (11) in a way that allows the multilayer component (10) to be mechanically and electrically joined to other elements, it is provided that an intermediate layer (14) of the multilayer component (10) be displaced in the region of the joining site (32), and that the two outer structural elements (12, 13) of the multilayer component be joined to one another by applying an electric voltage; and that the other component (11) be joined as a fastening element to the multilayer component (10) in the region of the joining site (32).

Abstract: A welding device for joining components by resistance welding includes a pair of electrodes which can introduce an electrode force and an electrical welding current IS1 into the components, at least one further pair of electrodes which can introduce an electrode force and a further electrical welding current IS2 into the components, a power source which can generate the electrode forces, a coupling link which is mechanically connected between the power source and the pairs of electrodes and which can divide a total electrode force that can be generated by the power source into the electrode force and the further electrode force.

Abstract: A welding device (1) for joining components by means of resistance welding is proposed, comprising:—a pair of electrodes (15), by means of which an electrode force (21) and an electrical welding current IS1 can be introduced into the components,—at least one further pair of electrodes (17), by means of which an electrode force (23) and a further electrical welding current IS2 can be introduced into the components,—a power source (19), by means of which the electrode forces (21, 23) can be generated,—a coupling link (35), which is mechanically connected between the power source (19) and the pairs of electrodes (15, 17) and by means of which a total electrode force (27) that can be generated by the power source (19) can be divided into the electrode force (21) and the further electrode force (23).

Abstract: A planetary gear mechanism that follows or precedes a transmission, and consists of a housing, a sun wheel, at least two planet wheels, a planet arm, and a gear ring. There is a locking device for the housing, the gear ring, and a power take-off, and a locking device for the housing, the planet arm, and the power take-off.

Abstract: A one-arm sensing lever having a sensing cam and carrying a permanent magnet faces a spring-biased, two-arm rocking lever across the paper-feed path of a printer; in the absence of paper, the cam drops into the feed path and the magnet is now capable of attracting one arm of the rocking lever so that its other arm operates a switch.
