摘要： A retention assembly secures a hydrocarbon trap within an air intake path of an internal combustion engine. The hydrocarbon trap is positioned within a first air tube, such as an outlet duct of a clean air filter. A second air tube, such as an inlet portion of a clean air duct assembly, is fitted over a portion of the first air tube to enclose the hydrocarbon trap within the first air tube. A clamp is fitted over both the first and second air tubes. A plurality of radially-extending, circumferentially-spaced protrusions that are formed on an inner surface of the second air tube pass through a respective plurality of apertures formed in the first air tube and, under radial compression exerted by the clamp, engage an outer surface of the hydrocarbon trap, thereby securing the trap within the first air tube.

摘要： In a method for controlling the operation of an internal combustion engine, a target torque to be produced is determined in several steps: In a first step a torque requested by a user is determined and modified in subsequent steps by different functions, which reproduce the influences of at least one continuously determined working and/or operating parameter of the engine on the torque that is actually produced, in such a way that at the end of the steps the target torque required during the engine operation is defined and the engine operation and the determination of the working and/or operating parameter are monitored for errors. If errors occur, diagnostic values that describe or indicate the errors are generated and used to modify, in particular limit the target torque. The diagnostic values are individually assigned to the individual steps to modify the determination or modification of the torque performed in each step.

摘要： A controller structure for more than two drive units coupled mechanically to a movable element includes a position measuring device for determining an actual position of the movable element and a position controller for calculating a setpoint speed from a setpoint position and the actual position, the position measuring device and the position controller jointly serving all drive units. Each drive unit, however, has a speed controller of its own. The drive units are configured either as master or as slave, individual drive units also being able to assume both functions. A torque-master-slave controller ensures a compensation of the torques between the drive units.

摘要： To be able to insert bands of an arbitrary length into a machine unit, for example intermediate carrier bands given an electrophotographic printer device, the band is seated on tubes. The tubes are pushed into receptacles arranged in the machine unit. The band can then be slipped over the transport and guide drums arranged in the machine unit. Subsequently, the band is tensed and the tubes are pulled from the receptacles.

摘要： To achieve great security against failure in lamps for medical applications, especially lamps for surgery, two electric bulbs are placed each in a concave mirror of ellipsoidal shape as part of a reflector, the two concave mirrors having focal points which are aligned with one another along an optical axis. The concave mirror provided to serve as the main lamp is configured as a ring reflector, while the concave mirror designed to operate as a reserve lamp closes off the reflector on the side facing away from the direction of emergence of the light. Thus, in the event of a change from main lamp operation to reserve lamp operation, the illuminated field is maintained at least approximately in its size and the location does not change (X and Y directions).

摘要： An aspirator pump, especially for medical purposes, has a receptacle with two chambers arranged alongside each other, which are connected with a suction tube, and on each of which an element is arranged which is movable approximately parallel to the other, each partially enclosing a hollow space for generating a vacuum. The two movable elements are connected to each other by means of a lever, whose two end parts are attached at the upper area of the respective movable elements, and whose middle part is movably attached in a bearing positioned between the chambers. In the upper area of each movable element a one way valve is installed which opens when the pressure in the hollow space is higher than the surrounding air pressure. An easy operation and cleaning, as well as a reliable aspiration is obtained with the aspirator pump, owing to the fact that at all times a chamber and a movable element enclose a common, variable hollow space, wherein the movable element bounds the upper area of the hollow space. The two hollow spaces are connected through a common manifold with a connection for the suction tube of a catheter, and an additional one way valve is arranged at the entrance of each hollow space into the manifold, which closes when the pressure in the hollow space is greater than the surrounding pressure.
