Abstract: A trimmer head for a trimmer has a base member having a trimmer line opening. A clamping device arranged in the base member clamps a trimmer line that defines a cutting plane when rotated. The clamping member of the clamping device is rotatably disposed on a pivot bolt having a pivot axis positioned in a plane that is parallel to the cutting plane. The clamping member is spring-loaded by a clamping spring into a clamping position. The trimmer line is secured in the clamping position between a clamping surface and the clamping member. A centrifugal force acting on the trimmer line loads the clamping member in the clamping position. A U-shaped bracket has bracket legs connected by a stay. The clamping member is positioned between the bracket legs. The pivot bolt is supported on the bracket leg ends. The stay of the U-shaped bracket forms the clamping surface.

Abstract: The invention relates to a device for performing heat treatments comprising at least one treatment module (10), which has a first and a second heating section (11a, 11b). Hot air (L) is introduced into the heating sections (11a, 11b) via a line connection (13). After the treatment, the hot air (L) is discharged via suction means (14). The suction means are arranged at the end faces of the heating sections (11a, 11b).

Abstract: An ignition device for a motor unit with an internal combustion engine provided with a piston, a combustion chamber with a spark plug, a crankshaft driven by the piston, an intake port supplying combustion air to the combustion chamber, an exhaust for removing combustion gases from the combustion chamber, a signal generator driven by the crankshaft and emitting for one crankshaft revolution an alternating voltage signal, has an ignition unit that triggers a spark at the spark plug at a preselectable timing. The ignition unit is a module separate from the motor unit. An alternating voltage signal generated by the signal generator is supplied to the ignition unit as an information signal sufficient for operating the internal combustion engine. The alternating voltage signal is supplied to a first unit for energy processing and to a second unit for processing information for control of the internal combustion engine.

Abstract: A carrying system for an implement, comprising a carrying arm and a receiving device held on the carrying arm for receiving the guide rod of the implement. In a first state, the receiving device is adapted to fix the guide rod in a longitudinal direction thereof. In a second state, the receiving device is displaceable in the longitudinal direction of the guide rod.
