摘要:
A valve arrangement for injecting a gas into a polyvinyl chloride fluid suspension, through an inlet port in the bottom of the suspension tank. The valve includes an overhanging upper disk with a hollow foraminated cylinder, so that the gas exits the cylinder under pressure through the foraminations, thus keeping the operating portion of the valve free of the suspension, with the valve disk overhang providing additional protection against intrusion of suspension material into the clearance space between the valve cylinder and surrounding injection tube. The valve disk overhang terminates in a pointed ridge which engages the top of the injection tube to form a seal.

A method for decoding a data stream containing audio/video substreams and control substreams comprises buffering nodes having the possibility to buffer multiple data packets in the same buffer. This may be achieved by having separate parameters for the allocated buffer size and any stored packet. Thus, not only multiple packets may be stored in the buffering node, but also such node may exist while its buffer is empty, so that the node may be reused later. This is particularly useful for buffering and selectively accessing multiple audio packets in MPEG-4 audio nodes or sound nodes.

A cutlery holder for positionably retaining a plurality of cutlery items in either a horizontal orientation or in an inclined orientation. The cutlery holder includes a body portion having a plurality of slots formed therein for receiving blade portions of cutlery items and a support stand connected to the body portion. The support stand has a first position for supporting the body portion such that the slots extend in a horizontal orientation and a second position for supporting the body portion such that the slots extend in an inclined orientation.

A method and an apparatus for creating a data block (Error Correction Code Block) comprising a plurality of data sectors, which data block is provided with parity information, and a method and an apparatus for recovering data sectors from a data block provided with parity information. A method for encoding or decoding data streams, respectively, which has a reduced memory requirement and manages with two encoders or decoders, respectively, and an encoding or decoding unit, respectively, for implementing the method, are proposed. In the case of a method for creating an ECC block comprising a plurality of data sectors, the data sectors being buffer-stored in the form of a block with a plurality of rows in a memory organized in the form of rows and columns and being provided with parity information, successively received blocks of data sectors are written row by row alternately to the rows or columns, respectively, of the memory.

The invention relates to a joining connection of at least one exhaust-gas-carrying pipe of an internal-combustion engine having a fastening flange which is inserted in its duct and, on its opening edge situated inside the duct, is welded to the duct wall of the flange, and to a process for its manufacture. In order to provide in a simple manner an automating capacity of the manufacture of the joining connection which is reliable with respect to the process, at least one support projection is constructed in an axially position-defined manner on the duct wall. The support projection projects into the duct and the pipe rests directly on the support projection in the plug-in position in the axial direction. The interior wall of the pipe ends flush with the end edge or projects radially beyond it toward the inside.
