Abstract: A machine tool clamping device for clamping a laminar machining tool to a tool holder that is eccentrically movably mounted includes at least one clamping unit with at least one movably mounted clamping element. The machine tool clamping device also includes at least one slotted link movement unit configured to move the clamping element in at least one operating state so as to generate tensile stress in the laminar machining tool.

Abstract: The invention relates to a device for locking electrical devices (2) with battery packs (4) for power supply, in which the electrical devices (2) have one movable locking bar (14; 36; 38; 40; 42) and the battery packs (4) have at least two recesses (24, 26), and upon locking, the recesses (24, 26) are located one after the other in the direction of a relative motion between the electrical device (2) and the battery pack (4), and after locking, the locking bar (14; 36; 38; 40; 42) engages one of the recesses (24, 26).

Abstract: A device for locking a power tool and a rechargeable battery pack that is insertable in a guide of the power tool has a locking bar installable on a housing of the power tool and held in locking engagement with the rechargeable battery pack via spring force, a release mechanism that acts on the locking bar for manually releasing the locking bar from the locking engagement, the locking bar and the release mechanism forming a lever that is pivotally supportable in a rocker pivot on the housing, the locking bar being fixedly held via spring force and a recess formed at a top side of the rechargeable battery pack and is releasable by pivoting the lever from the locking engagement via a compression force applied to the release mechanism, which extends upwardly across a front base end of the housing.

Abstract: The invention relates to a device for locking electric appliances (2) with battery packs (4) for power supply, whereby the electric appliances (2) comprise a displaceable bolt (14; 36; 38; 40; 42) and the battery packs (4) comprise at least two recesses (24, 26) and the recesses (24, 26) are arranged serially behind each other in the direction of a relative movement of the electric appliance (2) and battery pack (4) and, after locking, the bolt (14; 36; 38; 40; 42) engages in one of the recesses (24, 26).

Abstract: A method and apparatus for converting AC power into DC power are disclosed, where the method includes receiving the AC power, and converting the AC power into the DC power by way of a rectification device, where the rectification device is capable of being controlled to switch on at a plurality of time instants. The method further includes experiencing at least one of a first reduction in a first characteristic of the received AC power and a second reduction in a second characteristic of the DC power; and changing at least one of the time instants at which the rectification device is to be switched on.

Abstract: An electric hand-held power tool, in particular a power drill or screwdriver, is disclosed, which has a chuck (14) for a tool, a drive spindle (13) which drives the chuck (14) and protrudes with a spindle head (131) into a recess (15) embodied in the chuck (14), and connecting means, operative between the spindle head (131) and the recess (15), for connecting the drive spindle (13) and the chuck (14) in a manner fixed against relative rotation. For achieving a connection between the chuck (14) and the drive spindle (13) that is very simple from a production standpoint and hence economical and that even in drive spindles with a reversible direction of rotation assures reliable, non-rescindable torque transmission, the connecting means have axially extending cutting edges (26), embodied on the spindle head (131), that cut into the wall of the recess (15) when the chuck (14) is being slipped onto the spindle head (131) (FIG. 2).
