Abstract: The invention relates to an air jet sieve device having a housing, at least one sieve for insertion in the housing, a sieve deck and chamber located below the sieve, a slotted nozzle beneath the sieve deck, a drive for the slotted nozzle, an air inlet to the slotted nozzle, an air outlet through the housing and out of the chamber located beneath the sieve deck, and a control unit to control operation of the device. The invention also relates to a method that permits not only detection of the sieving progress during a sieving process but also provides a criterion to permit establishing the sieving time. This is achieved by equipping the sieving machine with a measuring sensor through which the particles in the air outlet flow are detected triboelectrically and which are correlated with the sieving progress to permit establishing the sieving time.

Abstract: The invention relates to a clamping device (8) for connecting a saw blade (12) to a reciprocating rod (6) of a jig saw, in particular a hand-operated compass saw (2), comprising a mounting (20), which is connected to the reciprocating rod (6) and has a recess (22) for receiving a head end (10) of the saw blade (12), a locking sleeve (30), which can be turned about the axis (40) with respect to the mounting (20) against the force of a torsion spring (60) to lock the head end (10) of the saw blade (12) in a locking position in the recess (22) and to allow removal of the saw blade (12) in a removal position. It is intended that a stop (78) interacts with a part (80) of the torsion spring (60), in order to prevent movement of the locking sleeve (30) beyond the removal position.

Abstract: A handheld power tool includes a housing (12) and a foot plate (14) for guidance on a surface of a workpiece. A pump unit (16), preferably located in the foot plate (14), drives a coolant and/or lubricant flow (18) for cooling and/or lubricating at least one heavy-duty component (20).

Abstract: The invention relates to a hand-held jigsaw, especially a compass saw, having a housing and a lifting rod with a pendulum mechanism, especially a pendulum lever, with which a pendulum stroke can be given during sawing to a saw blade carried by the lifting rod, especially a jigsaw blade. According to the invention, the hand-held jigsaw can be used more safely and in more special applications as the lifting rod is arranged such that it can rotate about the axis thereof and pivot transversely to the axis, and the pendulum mechanism can rotate about the axis.

Abstract: The invention relates to a power tool (1), which is designed as a jigsaw (2) and which comprises a rear support (2) for the saw blade (8) at a right angle to the rotational axis (22) of the saw blade (8). Said support (20) is designed as an element that is carried along by the saw blade in the rotational direction.

Abstract: The invention relates to a power tool (1), which is designed as a jigsaw (2) and which comprises a rear support (2) for the saw blade (8) at a right angle to the rotational axis (22) of the saw blade (8). Said driven support (20) allows adjustment of the saw blade (8) in different angular positions in the rotational direction around its rotational axis (22).
