A handheld power tool with a rotatable tool, in which the handheld power tool is a saw blade or milling cutter. The handheld power tool includes a sensor device for detecting a mechanical vector quantity. The mechanical vector quantity includes a force, an acceleration, a velocity, a deflection, a deformation and/or a mechanical stress and the mechanical vector quantity depends on a force emanating from the handheld tool. The handheld power tool also includes a control device which is communicatively coupled to the sensor device and is adapted to recognize an event and/or a state of the power tool according to a direction and/or change of direction of the mechanical vector quantity detected by the sensor device.

Power tool and method

A drive for a leaf of a door, window, or the like, including a mechanical energy store () configured to store energy during an opening movement of the leaf and expend energy during a closing movement of the leaf, an electric motor () operatively connected to the leaf via a motor shaft (), the electric motor () operated as a generator to dampen the opening movement and the closing movement. The electric motor including a control unit configured to control the electric motor, wherein a drive behavior of the control unit is repeatedly and variably adaptable to a current need of a user.

Drive for a door leaf or window leaf

A drive unit for closing a leaf of a door or a window comprises an energy accumulator for providing a closing force for closing the leaf, a damping device which counteracts the closing force and has an electric motor which can be operated as a generator and can be coupled to an actuating element of the drive unit, and a control device for controlling the electric motor. The control device is designed to determine a nominal path curve which indicates a position of the leaf or a closing speed of the leaf in dependence upon time, and to perform the control of the electric motor in order to damp the closing movement of the leaf on the basis of the established target path curve.

Drive unit

The invention relates to a system and method for fastening a heating/cooling element () to a wall or to a floor, the method comprising the following steps:

System and method for fastening a heating or cooling body

A machining device for material-removing machining of a workpiece includes a stationary frame, a workpiece magazine, a workpiece slide movable relative to the frame and accommodates a workpiece and a housing which encompasses a machining chamber and is located outside the workpiece magazine, wherein the workpiece magazine accommodates a plurality of workpieces, the workpiece magazine moves workpieces to an interchange point, the workpiece slide imparts translational movement to a workpiece along an X axis during workpiece machining and the workpiece slide is movable along the X axis to such an extent that the workpiece located on the workpiece slide is movable to the interchange point disposed outside the machining chamber encompassed by the housing.

Machine tool having workpiece hopper

At least a motor, a gear unit and an adjustment connection form an actuator. The gear unit is fitted with at least two mutually movable gear parts, as well as a spring acting on two of these that counteracts their movement out of an idle state. The gear unit is designed such that when an adjustment connection is blocked the motor moves the gear parts out of the idle state during operation to an operating point. In addition, the gear unit is designed such that during the movement out of the idle state it reduces the extent to which the movement is counteracted from a particular point upstream of the operating point.

Actuator

The mechanical coupling of an actuating element of a valve to a connection element of an actuator is accomplished with the actuating element able to be displaced along a z-axis for the purpose of adjusting the valve and the connection element, at a corresponding orientation of the actuator, can likewise be displaced along the z-axis relative to the valve by the actuator. The device has (a) a first coupling element which can be coupled to the actuating element so that a certain freedom of movement is provided between the first coupling element and the actuating element along the z-axis, (b) a second coupling element which can be coupled to the connecting element, (c) a connecting element which links the two coupling elements to each other in a movable manner, and (d) a clamping device which is arranged on the first coupling element and/or on the second coupling element and which is embodied such that, upon an actuation of the clamping element the two coupling elements are braced against each other, and an actuating element coupled to the first coupling element is clamped without play to the two coupling elements along the z axis.

Coupling actuating element of valve to connection element of actuator

A device is described for mechanically coupling an actuator to a valve which is adjustable by a plunger that is displaceable along a z-axis. The device has (a) a retaining element which can be mounted on a connecting chassis of the actuator and which is embodied for engaging on two opposite sides of a connection piece of a valve body in a recess incorporated in the connection piece, and (b) a clamping device which is disposed on a section of the retaining element and which is embodied in such a way that when the clamping device is actuated the section of the retaining element is displaced parallel to the z-axis relative to the connecting chassis such that the connecting chassis bears against the connection piece. An actuator having a coupling device of said kind and a method for mechanically coupling an actuator to a valve are also described.

Coupling an actuator to a valve using a retaining element engaging in a recess

A valve of a heating, ventilation and/or air conditioning system includes an actuator with a housing and a shaft which is arranged at least partially in the housing and which can be coupled directly or indirectly to the valve such that the valve can be adjusted during a rotation of the shaft. A hand-operated element can be coupled to the shaft via an overload clutch arranged between the hand-operated element and the shaft which limits a torque which is transmitted onto the shaft by the hand-operated element to a predetermined maximum value. The overload clutch has a coupling element and a replaceable spring element which presses the coupling element against the shaft such that the maximum value for the transmittable torque is dependent on the replaceable spring element.
