Abstract: Variable-format web-fed offset printing machine having printing-unit cylinders comprising core cylinders to which compressed air can be applied and onto which intermediate sleeves can be pushed axially and shrunk on radially. Each intermediate sleeve includes a carrier layer whose inner face rests on the core cylinder, a compressible intermediate layer, a transition layer, and a variable-thickness bridging layer, which ends with a covering layer to which a further surface like a printing plate or a rubber blanket can be fitted.

Abstract: The invention relates to a radio communications device in which at least one additional SAR value-reducing correction element (KE1) is provided in and/or on the housing (GH) in such a manner that the distribution of any electric current (EC1) which might be flowing on the printed circuit board (LP) is effected from one or more local maxima (MA) thereof up to the correction element (KE1). When using the mobile radio device (MP1), a homogenization and/or a shift thus adjusts with regard to the local distribution of the overall resulting electric current (EC1*).

Abstract: The invention relates to an antenna arrangement on a mobile communication terminal, in particular on a mobile telephone, comprising an appliance housing and, within said appliance housing, electronic components and metallic parts arranged on a communication terminal board (1) as well as a mass surface. The antenna arrangement has an irradiating element (5), arranged within the appliance housing, comprising a structure and, between the irradiating element (5) and the communication terminal board (1) are means to protect the irradiating element (5) against disturbances caused by the electronic components or metallic parts, which are connected to the mass surface of the communication terminal board (1).

Abstract: The present invention is directed to an antenna for radio-operated communication terminal devices. For effecting a multi-band antenna, a planar inverted-F antenna is provided that is designed in size for a predetermined, lower emission frequency and that includes one or more notchings or graduations in longitudinal direction with which one or more geometrical paths derive over whose course emittable waves form with a higher frequency than the predetermined, lower frequency.

Abstract: A tunable antenna includes separate radiator parts coupled to one another. The coupling between the parts is changed by rotating and/or displacing the parts with respect to one another such that the antenna exhibits a radiation pattern associated with a respective degree of a rotation and/or displacement. A process for manufacturing such antennas includes constructing parts for a respective antenna, coupling the parts to one another to permit them to rotate and/or displace, measuring the radiation pattern of the parts, and adjusting the radiation pattern by rotating and/or displacing the parts with respect to one another to set a nominal radiation pattern of the respective antenna formed by the parts. The couple is changed by rotation and/or displacement of the parts. A respective degree of rotation and/or displacement creates a corresponding change of a radiation pattern of the parts.
