Abstract: The invention relates to a process for producing a shaped body by selective laser melting, in which a shaped body is built up from pulverulent metallic material using CAD data of a model, in which a powder layer is applied using an applicator unit, and in which the applied powder layer is fixed to a layer below it using a focused laser beam, in which process the powder layer is levelled to a desired layer thickness as a result of a levelling device passing over the shaped body at least once, and during the levelling elevations that project above the desired layer height of the applied powder, of the layer which was last melted by the laser beam are uncovered by the levelling device.

Abstract: In a method for the personal management of parameter lists for an audio and/or video device (2a, 2b) by at least one user, an access facility (5a, 5b) is used to access, via a data network (7), a storage facility (4) connected to the audio and/or video device (2a, 2b), which storage facility (4) stores the parameter lists to be managed, which contain parameters for the audio and/or video device (2a, 2b), the access facility (5a, 5b) enabling amendment of the parameter lists to be managed in respect of the list entries contained therein.

Abstract: At a playback device (10) comprising at least one signal processing means for processing a signal and switching means for switching the playback device (10) into a demonstration mode a demonstration of an inherent function of the playback device (10) can be performed. Therein supply means (40) for supplying demonstration data for the demonstration and data reading means (40) for reading demonstration control data of a data carrier (41) which comprises demonstration control data for performing the demonstration are embodied as well as processing means (53) for processing the demonstration control data such that the demonstration data are transmittable to the at least one signal processing means during processing of the demonstration control data.

Abstract: A machine for the multi-stroke, continuous slotting of plate-shaped workpieces and especially sheet metal plates is described. A slotting tool (16) and the workpiece are movable in a forward direction relative to each other in a gate-cutting function and in at least one subsequent slot cutting stroke. This is followed by a return movement in the opposite direction (32) over a return length (A) that corresponds at a maximum to the length of the previously laterally cut slot. This is followed by a cross-cutting stroke in which the strip of material (31) that was laterally cut in the gate-cutting function and the minimum of one subsequent slotting stroke is severed at a distance from the point of its connection to the remaining workpiece. The slotting tool (16) is driven by a cam drive with a drive control, a return-drive system with a return-drive control and a forward-feed drive system with a feed-drive control.

Abstract: The invention relates to a method and a device (12, 13) for producing a multi-layered three-dimensional component (14). In a first step, a layered geometrical structure is formed, said structure consisting of at least two webs (16) of an at least high temperature-resistant material. In a second step, an at least partly material connection is produced between the individual webs of the entire layered structure by means of at least one thermal treatment.

Abstract: A method and machine for the multi-stroke, continuous slotting of plate-shaped workpieces and especially sheet metal plates are described. As part of a method for the continuous multi-stroke slotting of plate-shaped workpieces, a slotting tool (16) and the workpiece are moved in an advance direction relative to each other in a gate-cutting function and is at least one subsequent slot cutting stroke. This is followed by a return movement in the opposite direction (32) over a return length (A) that corresponds at a maximum to the length of the previously laterally cut slot. This is followed by a cross-cutting stroke in which the strip of material (31) that was laterally cut in the gate-cutting function and the minimum of one subsequent slotting stroke is severed at a distance from the point of its connection to the remaining workpiece.

Abstract: An optical reflector, in particular for construction or geodetic surveying, has a reflective body (1) and a receptacle housing (3) for holding the reflective body (1). The reflective body (1) including transparent material has a transmission surface (5) and at least one unmetallized reflection surface (2). The receptacle housing (3) and the reflective body (1) held therein form a cavity. This is sealed water-tight from the environment of the reflector, for protecting the reflection surface (2). A structure for exchanging gas (4) is provided in the receptacle housing (3). A further development of the invention envisages detachable mounting of a component (17) on the reflector.

Abstract: A method and system facilitates the creation and maintenance of favorites lists (165) on the Internet (140). Devices (110) that have access to the Internet (140) have direct access to each of a user's favorites lists (165), and can be configured to facilitate modifying the favorites lists (165). Devices (110) that lack direct access to the Internet (140) are configured to receive ‘downloaded’ copies of lists (165) that are maintained on the Internet (140), and optionally to provide ‘uploadable’ copies of modified lists for updating the favorites lists (165).

Abstract: In a method for manufacturing a metallic or ceramic body constructed in layers from a real body elements, the a real body elements are cut out of a body material connected to a support material. Subsequently, the a real body elements are sequentially connected to a respective last applied layer of a real body elements of the body to be manufactured by a physical or chemical connecting process. After connection with the last applied layer, the support material is removed from the a real body elements.
