摘要： An elastic connecting support for arrangement between a combustion engine and an air filter of a handheld work apparatus is disclosed. The connecting support has a first channel for largely fuel-free air and a second channel for a fuel/air mixture. The connecting support is realized as a single piece, and has, on a first side, an engine connecting flange, at which the first and second channel end, for connection to the combustion engine. The first channel has a first peripheral wall and the second channel has a second peripheral wall. The first peripheral wall and the second peripheral wall are arranged at a distance in relation to each other in a longitudinal section of the connecting support. The channels extend from the first side to a second side of the connecting support. On the second side, the first channel and the second channel end at a common connecting flange.

摘要： A ground working system includes at least one self-driving ground working device having a drive, a control unit and a battery. An operating region is determined by a boundary wire, wherein the ground working device travels over a traveling path determined by the control unit in the operating region. Connected to the boundary wire is a first base station, which transmits a signal on the boundary wire. The electromagnetic field of the signal induces a reception signal in the reception coil of the ground working device. The reception signal is processed in the control unit. In order to make a stable signal available over the entire length of the boundary wire, it is provided that the boundary wire is electrically connected to a further base station configured as a repeater, which receives the signal transmitted by the first base station, processes it and passes it on.

摘要： In a method for determining at least one fitting parameter for a spectacle lens received in a spectacle frame, an image, lying in an image plane, of at least one portion of a spectacle frame worn by a subject is acquired. When acquiring the image, the inclination of the image plane about a horizontal axis which is parallel to the image plane is established and, in the process, the at least one fitting parameter is established from the acquired image of the portion of the subject with the spectacle frame worn by the subject and the established inclination of the image.

摘要： A method is for the safe starting of a combustion engine in a handheld, portable work apparatus. When starting, start rpm limiting is activated when the rotational speed of the combustion engine exceeds an activation rotational speed that lies above the coupling rotational speed of a centrifugal coupling. After activating the start rpm limiting for at least one working cycle, an intervention in the ignition is carried out such that the rotational speed of the combustion engine decreases. After the rotational speed has decreased below a lower engagement rotational speed, an intervention in the ignition is carried out such that the rotational speed increases. If the rotational speed exceeds an upper engagement rotational speed, an intervention in the ignition is again carried out such that the rotational speed decreases. The upper engagement rotational speed and/or the lower engagement rotational speed is/are changed with an increasing number of consecutive working cycles.

摘要： A start device is for a chainsaw having a combustion engine. The start device includes an electric motor with a control device, which initiates operation of the electric motor and starts up the combustion engine. The chainsaw has a brake device for bringing the tool to a standstill, wherein the brake device can be operated via an actuation lever. For this purpose, the actuation lever can be moved from a first position (A) into at least one further position (B). The control device is connected to a signal transmitter, which is actuated, and emits a signal to the control device, when the actuation lever is moved from the first position (A) into the further position (B), wherein the signal forms a start signal for initiating operation of the electric motor and for starting up the combustion engine.

摘要： A carburetor for the combustion engine in a handheld work apparatus has a carburetor housing in which a carburetor drum is mounted rotatably about a pivot axis. The carburetor drum has a drum body which has at least one channel which runs transversely with respect to the pivot axis and forms an intake channel portion. A sensing unit for sensing at least one rotational position of the carburetor drum is provided. The sensing unit includes a control contour and a sensing device interacting with the control contour. The control contour is formed on the carburetor drum. A method for operating a combustion engine makes provision for the control device to control the supplied quantity of fuel depending on the rotational position, sensed by the sensing unit, of the carburetor drum.

摘要： A metering roller is for filling a vessel with a portion of a powder product to be metered. The metering roller includes a roller jacket, a filter element, a filter strip, a seal and a clamping core. The roller jacket defines at least one metering opening completely penetrating the roller jacket from its outer side to its inner side, the metering opening being delimited on the inside via a filter element. The filter element is pressed by the clamping core via the filter strip against the inner side of the roller jacket. The seal is arranged between the filter element and the filter strip, the metering opening being exposed to a negative pressure through the filter element via at least one pressure channel in the filter strip. The seal seals a connection of the pressure channel to the metering opening. The seal is an elastomer cured onto the filter strip.

摘要： A method for producing an optical element having a main body with a first side surface, which has a first optical coating, and at least one second side surface, which is not plane-parallel to the first side surface and has a second optical coating, is proposed. The method includes the steps of: determining the stress induced in the optical element by the first optical coating of the first side surface; determining a counter-stress, so that the resultant overall stress induced in the optical element is as small as possible; determining the second optical coating while taking into account the determined counter-stress and the optical parameters of the second optical coating; applying the first optical coating on the first side surface; and, applying the second optical coating on the at least one second side surface.
