Abstract: A pump arrangement having a unit which comprises a material with a magnetocaloric action, an arrangement of conduits which are in the region of the unit and through which a liquid or gaseous heat-conduction medium flows and a pump system operating according to travelling-wave principles.

Abstract: A drive arrangement for a rotational body device comprising a shaft which is held rotatably with respect to a rotational axis, a first bearing module and a second bearing module, each with at least one elastic support element for supporting the shaft, an electric motor, an electrically actuable stabilisation device, and a housing. At least the first bearing module provides a mass body which is held in a non-rotatable fashion with respect to rotational axis by means of the at least one elastic support element. The shaft is supported in a rotatable fashion on the mass body by a bearing of the first bearing module.

Abstract: A process for electric bonding of an aluminum wire to a contact area which wire, provided with an oxide layer on its outer surface, is wrapped with an insulating lacquer and ultrasonic bonded to said contact area, wherein insulation is removed from the aluminum wire section to be connected to the contact area prior to the ultrasonic bonding process by removing the insulating layer which surrounds the outer surface of the wire with oxide layer by means of an electric plasma.

Abstract: A lighting device for attachment to a motor vehicle inside a housing 4. One or more light emitting diodes 9 which emit substantially white light are employed as lighting emitters. On account of the small amount of waste heat of the light-emitting diodes 9 the lighting device can be particularly easily integrated into existing subassemblies of the motor vehicle, in particular into the outside mirrors, inside mirror, trim strips and door handles, and can serve to illuminate the region around the vehicle or the interior of the vehicle.

Abstract: A lighting device (26) for arrangement on the external or internal rear view mirror of a motor vehicle is provided with a light source (27), the light rays of which emerge at a mirror housing opening and are deflected at a transparent light refraction element (33) arranged in the beam path. The plate-like light refraction element (33) has, at least on one side, a surface structure (36) by means of which the light refraction element is divided into several light refraction zones. To achieve a deflection of the light into a preferred direction the light refraction element (33) is designed in the manner of a Fresnel prism (33), the light refraction zones corresponding to prism zones of a prism body which are pushed together in stepwise manner. To intensify the deflection of the light beam into the preferred direction a decentralized condenser lens (31) may be arranged in front of the Fresnel prism (33).

Abstract: An outside rear view mirror for a motor vehicle includes a mirror element, a housing and a mirror foot fastenable to the motor vehicle. At least one electrical function element, in particular a contacting element, is provided in the outside rear view mirror. In order in a simple manner to protect the function element (9, 19, 20, 29, 30, 31) from moisture and dirt, there is provided in the outside rear view mirror (1) a sealable chamber (5), in which the electrical function element (9, 19, 20, 29, 30, 31) may be disposed.

Abstract: A line (3) provided between the head space (11) of the fuel tank (10) and the induction tube (1) of the engine contains an absorption element (9) and can be shut off by a signal-actuated servo valve (8) connected to the outlet from the absorption element. The line (3) is provided with a first sensor (4) preceding the absorption element (9) and detecting gas flows. A vacuum actuator (12) following the servo valve (8) is provided with a second sensor (13) which gives a signal when actuated. The first sensor (4) and the second sensor (13) are connected for carrying signals to a diagnosis block (14) which compares them with the signal (17) actuating the servo valve (8) and uses them for fault diagnosis.
