Abstract: A refrigeration appliance includes a door having a door rack or racks on the inside of a door leaf and a surface luminaire or lighting fixture disposed substantially perpendicular to the door leaf. The surface luminaire extends in the vertical direction beyond the door rack or racks and serves to illuminate an interior storage space. The surface luminaire is preferably an OLED.

Abstract: A beverage dispenser has a housing enclosing a dispenser recess, at least one light inlet window for lighting the dispenser recess, a printed circuit board, on which a number of LEDs are arranged to feed light into the dispenser recess by way of the at least one light inlet window. The printed circuit board is mounted on the housing of the dispenser recess above an LED housing, which seals the light inlet window.

Abstract: A method for operating an internal combustion engine with multiple cylinders. Each cylinder of the internal combustion engine includes at least one fuel injector, and each fuel injector is activated for opening and closing via a solenoid valve of the respective fuel injector. Structure-borne sound waves emitted by the fuel injectors and/or accelerations caused by the fuel injectors are detected by measurement. The structure-borne sound waves detected by measurement and/or the accelerations detected by measurement are evaluated, and based on the evaluation, characteristics of the fuel injectors are automatically determined.

Abstract: A household refrigeration device includes a heat-insulated body with an inner container which delimits a coolable interior space for storing foodstuffs and has a pocket-shaped recess with a bottom. A refrigeration device cools the coolable interior space. A door panel closes the coolable interior space in a closed state and makes the coolable interior space accessible in an open state. An interior lighting system, which is fastened in the pocket-shaped recess, illuminates the coolable interior space when the door panel is open. The bottom of the pocket-shaped recess includes at least one fastening device, and the interior lighting system has at least one mating fastening device which is fastened on the at least one fastening device. A method for producing a household refrigeration device is also provided.

Abstract: A domestic refrigeration appliance includes a thermally insulated body having an internal container which delimits a coolable interior provided for the storage of food, a refrigeration apparatus for cooling the coolable interior space and a door leaf which is provided to close the coolable interior in a closed state and to make the coolable interior accessible in an open state. An interior lighting system includes at least one lighting device for at least partially lighting the coolable interior when the door leaf is open. A light color of light generated by the interior lighting system can be set or adjusted.

Abstract: A domestic refrigeration device includes a thermally insulated body with an internal compartment delimiting an interior coolable food storage space, a refrigeration apparatus cooling the interior space, a door leaf closing the interior space in a closed state and making the interior space accessible in an open state, and an interior lighting configuration illuminating the interior space with the door leaf open. The interior space has side walls with a depth, edges facing the door leaf, a ceiling and a rear wall rearwardly closing the interior space. The lighting configuration includes a first partial interior lighting configuration illuminating the interior space only at least approximately starting from a distance or space measured from the edges of the side walls facing the door leaf to the rear wall, and a second independent partial interior lighting configuration illuminating only a front region of the interior space facing the door leaf.

Abstract: An illumination apparatus includes at least one illumination device and an elongated optical waveguide. The optical waveguide has a length, two ends, a back side and a front side opposite the back side. One of the two ends is optically coupled to the at least one illumination device, or each of the two ends is optically coupled to at least one illumination device. The back side of the optical waveguide has a coupling-out structure, which is an integral component of the back side of the optical waveguide and is configured to couple the light coupled into the optical waveguide out of the optical waveguide at least over a majority of the entire length of the optical waveguide through the front side of the optical waveguide. A domestic refrigeration appliance having such an illumination apparatus as an interior illumination apparatus is also provided.

The surface luminaire extends in the vertical direction beyond the door rack or racks and serves to illuminate an interior storage space. The surface luminaire is preferably an OLED.

Abstract: Racemic metallocene complexes are prepared by reacting bridged or unbridged transition metal complexes with cyclopentadienyl derivatives of alkali metals or alkaline earth metals and, if desired, subsequently replacing the aromatic ligands.
