Abstract: A passive illumination device for use with at least one light source unit of an image receiver, in particular of a code reading device and/or code verification device, has at least one diffuser unit which is configured for converting light provided by the light source unit into at least substantially diffuse illumination light for an illumination of at least one illumination region and which comprises at least one diffuser element with at least one diffusion shell for a scattering of the light.

Abstract: An apparatus for decoding a sequence of pictures from a data stream is configured for decoding a picture of the sequence by: deriving a residual transform signal of the picture from the data stream; combining the residual transform signal with a buffered transform signal of a previous picture of the sequence so as to obtain a transform signal of the picture, the transform signal representing the picture in spectral components; and subjecting the transform signal to a spectral-to-spatial transformation, wherein the buffered transform signal comprises a selection out of spectral components representing the previous picture.

Abstract: A connecting apparatus includes a first connecting part, which has a first basic body and at least one engagement protrusion arranged rigidly on the first basic body, and a second connecting part, which is attachable to the first connecting part in a closing direction and which has a second basic body with an engagement portion arranged rigidly on the second basic body. The first connecting part has a first magnetic device and the second connecting part has a second magnetic device. The first magnetic device and the second magnetic device interact in a magnetically attracting manner along the closing direction to assist the attachment of the first connecting part and the second connecting part to each other. The first connecting part has a blocking portion which is designed, in the connected position, to interact with the second connecting part in order to block the engagement of the engagement portion with the at least one engagement protrusion counter to an engagement direction.

Abstract: An optimized utilization of the resources of a mobile radio network including a number of channels suitable both for the transmission of data and of voice is achieved by a mobile radio telecommunication network and a method for allocating a channel requested for a telecommunication link via a telecommunication network between a caller and a called party. Preferentially, a physical channel having a different wanted-to-unwanted signal ratio is selected when a data channel is requested than when a voice channel is requested.

Abstract: The invention relates to a process for producing tenside-stabilized colloids of mono- and bimetals of the group VIII and Ib of the periodic system which are isolable in the form of powder and which are soluble at a concentration of at least 10 mg atom of metal/l of water, from metal salts in the presence of strongly hydrophilic tensides with hydrotriorganoborates in THF, or with simple chemical reduction agents like hydrogen or alkali formate in water and alcohols, respectively. Furthermore, the subject matter of the invention is the use of tenside-stabilized colloids which are produced according to this process as precursor for supported catalysts for the selective cis-hydrogenation of C--C triple bonds, for the selective hydrogenation of functional groups at the aromatic nucleus, for the selective hydrogenation of benzene to cyclohexene, for the partial oxidation of the primary alcohol functionality in carbohydrates, as well as for use as a precursor for electrocatalysts in fuel cells.

Abstract: Across the gas flow path in a duct such as for air conditioning there is placed a composite filter set comprising a plurality of filter elements and means joining said elements, each of said filter elements comprising a plurality of filter pockets and a frame holding said pockets at their open ends, and said joining means connecting the frames of adjacent filter elements in a manner to form a gas-tight seal therebetween so that flowing gas can advance only by passage through one of said filter pockets.

Abstract: In an open end spinning unit having a stationary frame member and a spinning rotor rotatably supported by the frame member, and in which, during operation of the unit, a flow of gas occurs from the yarn removal opening and fiber inlet opening of the unit to a gas extraction opening thereof, the gas traversing a path surrounding the rotor, a gas flow controlling structure is disposed around the rotor to define a narrow gap with the exterior surface of a portion of the rotor, so that the space adjacent the remainder of the rotor is in communication with the gas flow path only via the narrow gap.
