    Abstract: A feed roll and stripper assembly for a rolling mill includes at least one feed roll at each of an entry side and an exit side of a pair of work rolls and a stripper at each of the entry and exit side of the pair of work rolls. Each stripper has a stripper tip. At least one of the strippers or feed rolls are adapted to have an adjustable vertical separation from one of the work rolls, according to the direction of movement of material through the work rolls. The vertical separation of the at least one stripper or feed roll from the one work roll on the entry or exit side is different from the vertical separation of the other at least one stripper or the feed roll on the other of the entry or exit side. Each stripper tip is separated from one of the work rolls.

    Abstract: An improved system and method for writing data dependent upon multiple reads in a distributed database is provided. A client may read several data records and may then send a request to a database server to perform a transaction to write a data record dependent upon multiple data records read. A database server may receive the request specifying a transaction to write a data record dependent upon multiple data records read and may perform the transaction by latching a master data record to be written and validating the data records the write depends upon. The multiple data records upon which the write depends may be validated by verifying the multiple data records are current versions of the data records stored in the distributed database. Data intensive applications may use this transaction type in large scale distributed database systems to provide stronger consistency without significantly degrading performance and scalability.

    Abstract: The invention relates to the design of multiple piece rolls, in particular backup rolls, for the use in metal rolling. The roll comprises a main part with a center bore for the removal of center defects or flaws arising from the manufacturing process, e.g., from casing or forging and at least an end part, whereas the end part has no center bore or a center bore with a diameter smaller than the bore diameter of the main part.

    Abstract: An improved system and method for applying once a transaction delivered in a message published asynchronously in a distributed database is provided. In various embodiments, apply once messaging may be achieved for asynchronous publication by having a persistent log stored on a messaging server. A messaging server may receive an update message for a transaction to be published asynchronously in a distributed database, may generate a sequence number for the transaction in a message, and may log the update message with the sequence number in a log file persistently stored on the messaging server. The messaging server may then send an acknowledgement that the update message is published and may asynchronously publish the update message with the sequence number to subscribers. The publication may only succeed if there may not be any message tagged with a sequence number that has been previously published by the messaging server.

    Abstract: An improved system and method for loading records into a partitioned database table is provided. A translation of records may be generated from a set of source partitions to a set of target partitions by generating a bipartite graph, determining a maximal matching using dynamic programming for a chain of nodes remaining in the bipartite graph after removing singleton edges, and generating a maximal matching after adding back the singleton edges for translation of records from the set of source partitions to the set of target partitions. The partition translation may be executed by traversing from top to bottom the set of source partitions and the set of target partitions in record key order to generate an optimal sequence of operations to transfer the records from the set of source partitions to the set of target partitions.
