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 rip fence module for positioning workpieces with their edge facing away from a tool on a machine table at a certain distance to the tool, comprising: a superstructure overlapping the machine table presenting a workpiece stop for the workpiece to be treated extending in a longitudinal direction, at least one guided portion which is insertable and guidable in an allocated guide groove provided on the machine table side extending in an extension direction transversely to the longitudinal direction, and by which the superstructure is supported movably in the guide groove in the extension direction relatively the tool, and a locking device shiftable between a locking position and a release position in order to lock the rip fence module in the locking position at a guided portion defined relatively the guide groove, and to permit in the release position a shifting of the guided portion in the guide groove.

Abstract: A tool-support apparatus for attachment to a grinding machine, in particular to a wet grinding machine, which has at least one grinding disc arranged on a rotatably drivable grinding-disc shaft and a machine frame or housing in which the grinding-disc shaft is supported. The tool-support apparatus has a tool-support, which can be secured on a machine frame or housing of the grinding machine, for the support during the grinding process of a tool that is to be ground, and an arresting apparatus for securing the tool support on the machine frame or housing. The tool-support can be secured on the machine frame or housing in such a way that it can be swivelled about the grinding-disc shaft or about a swivel axis parallel to the grinding-disc shaft and can be arrested by way of the arresting apparatus in a plurality of angular positions.

Abstract: The invention relates to a tool-support apparatus for attachment to a grinding machine (1), in particular to a wet grinding machine, which has at least one grinding disc (3) arranged on a rotatably drivable grinding-disc shaft (2) and a machine frame or housing (4) in which the grinding-disc shaft (2) is supported. The tool-support apparatus has a tool-support (5, 6, 7), which can be secured on a machine frame or housing (4) of the grinding machine (1), for the support during the grinding process of a tool that is to be ground, and an arresting apparatus (8) for securing the tool support (5, 6, 7) on the machine frame or housing (4). The invention is distinguished in that the tool-support (5, 6, 7) can be secured on the machine frame or housing (4) in such a way that it can be swivelled about the grinding-disc shaft (2) or about a swivel axis (10) parallel to the grinding-disc shaft (2) and can be arrested by way of the arresting apparatus (8) in a plurality of angular positions.

Abstract: The invention relates to a rip fence module for a machine tool (1), in particular a panel sizing circular saw (1) in order to position workpieces with their edge facing away from a tool (2) on a machine table (3) at a certain distance to the tool (2), comprising: a superstructure (9) overlapping the machine table (3) at least in sections presenting a workpiece stop (9d) for the workpiece to be treated extending in a longitudinal direction (L), at least one guided portion (24, 16g) which is insertable and guidable in an allocated guide groove (14a) provided on the machine table side extending in an extension direction (A) transversely to the longitudinal direction (L), and by which the superstructure (9) is supported movably in the guide groove (14a) in the extension direction (A) relatively the tool (2), and a locking device (16) shiftable between a locking position and a release position in order to lock the rip fence module in the locking position at a guided portion (24, 16g) defined relatively the guide g

Abstract: The invention relates to a table widening module for a machine tool (1), especially a panel sizing circular saw (1), with an extension element (5) comprising for widening of a machine table (3) an extension plate (8), which can be positioned adjacent to the machine table (3) in an extension direction (A) and is especially flush on top with the machine table (3), as well as a number of extension arms (7a, 7b) fastenable to the extension plate (8) and received in a guided manner in the extension direction (A) in an allocated number of guide rails (6a, 6b; 206a, 6b; 306a, 6b) fastened on the table so that the distance of the extension plate (8) to the machine table (3) is variable.
