摘要： A roll stand for a rolling mill, comprising: a support structure adapted to be fixed at a selected location along a mill center line. First and second work rolls are configured and arranged to roll products directed therebetween. The first work roll has roll necks journalled for rotation in bearings contained in first chocks, and the second work roll likewise has roll necks journalled for rotation in bearings contained in second chocks, with the first and second chocks of the work rolls being arranged in pairs located on opposite sides of the mill center line. The first and second chocks of each pair are connected to the support structure for pivotal movement respectively about parallel first and second connecting axes which extend in parallel relationship with respect to the axes of the rolls and orthogonally with respect to the mill center line. An adjustment mechanism is provided for simultaneously pivoting the first and second chocks of each pair in opposite directions about their respective connecting axes in order to symmetrically adjust the parting between the work rolls.

摘要： A flying shear has leader and follower blades rotating in opposite directions about parallel axes located above and below a horizontal plane. The radius of rotation of the leader blade is longer than the radius of rotation of the follower blade. The blades are configured and arranged to coact in a radially overlapping relationship at a cutting zone spaced vertically from the horizontal plane. A switch directs longitudinally moving products such as bars, rods and the like from the horizontal plane across the cutting zone for separation by the rotating blades into leading and trailing segments.

摘要： A shear is disclosed for subdividing an elongated product moving longitudinally in a horizontal plane. The shear includes upper and lower continuously rotating blades respectively coacting in a radially overlapping relationship at first and second laterally disposed cutting zones. An upstream switch operates to divert the product laterally across the cutting zones to separate a leading end from an intermediate section in the first cutting zone, and to separate a trailing end from the intermediate section in the second cutting zone.

摘要： Systems, methods, and other embodiments associated with maintaining referential integrity while masking database columns are described. One example method includes determining a transitive closure for dependency relationships involving a column to be masked and other columns related to the column to be masked through a dependency relationship. The example method may also include identifying a root column for a column in the transitive closure and creating a mapping table that stores original values and masking values for the root column. The method includes masking the root column and related child columns based on the mapping table in a manner that maintains referential integrity between the root column and the child column. Integrity may be maintained by masking corresponding values in the root column and a child column(s) with identical mask values from the mapping table.

摘要： Systems, methodologies, media, and other embodiments associated with producing non-repeating random values for use in data masking are described. One example method includes accessing data describing a mask for a value in a database table column to be masked. The example method may also include identifying a number of distinct values in the database table column to be masked and determining a field width for a mask to provide unique random numbers to mask the distinct values. The method may include identifying locations in a mask value to store the unique random value and locations in a mask value to store filler values. The mask value may include different character sets and may comply with user specified formats. The method may include generating a set of statements that when executed produce a mapping table that includes masks for distinct values in the database table column to be masked.
