A dust removal system handheld power tool includes a fan () to generate an air flow (), a suction nozzle () to capture dust-laden air from a tool (), and a collecting container () to collect the dust. The collecting container () has a suction opening () connected to the suction nozzle () as well as an exhaust opening () connected to the fan (). A filter () serves to separate dust into the collecting container () and is arranged so as to cover the exhaust opening (). The filter () has several consecutive fins () arranged one beside the other in a direction (y) that is perpendicular to the direction (z) of the air flow (). The fins () are slanted with respect to each other. The slant () of the fins () reduces the adhesion of the dust to the fins ().

Dust removal system for a handheld power tool

The present invention is concerned with a system for the oxygen supply of persons in an aircraft. In order to provide the simplest possible system, which is suitable in particular for a reconfiguration of the seat devices (), the system has at least one oxygen line, one oxygen feed, and multiple attachment points for oxygen masks (), the oxygen line extending in the longitudinal direction and the attachment points being connected to the oxygen line. The attachment points are preferably situated linearly and are spaced apart from one another in the longitudinal direction.

An auxiliary handle for a hand-held power tool has a handle piece, a fixation means for fixing the auxiliary handle to the hand-held power tool, a rod with at least one set of teeth, and a guide in which the rod is seated longitudinally movably. A locking mechanism has a pawl, a pivot axis about which the pawl can be rotated between a locking position and a release position, and at least one locking tooth on the pawl that engages in a locked position with the guide, and is pivoted out of the guide in a release position. A spring element initially tensions the pawl into the locking position. A distance of the spring element from the pivot axis is less than a distance of the locking tooth from the pivot axis.
