Abstract: A method, system and computer program product provides the capability to capture and store data object definitions in a database in a less costly and less time-consuming manner than previous techniques. A method of capturing and storing multiple versions of data item definitions in a database comprises generating a first version of information relating to a plurality of data item definitions in the database, and generating a second version of information relating to a plurality of data item definitions in the database by recapturing only information relating to those data item definitions that have changed since the first version was generated.

Abstract: A method, system, and computer program product provides the capability to compare data object definitions in a database in a less costly and less time-consuming manner than previous techniques. A method of comparing multiple versions of data item definitions in a database comprises generating a first version of comparison information relating to a plurality of data item definitions in the database by comparing information relating to data item definitions obtained from a first source and information relating to data item definitions obtained from a second source and generating a second version of comparison information relating to a plurality of data item definitions in the database by comparing information relating to data item definitions obtained from a first source and information relating to data item definitions obtained from a second source to the first version of comparison information.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A rolling mill assembly includes a support shaft having a tapered section leading from an abutment to an end section. A ring-shaped roll having inboard and outboard flanks and a cylindrical bore is axially mounted on the shaft with its inboard flank seated against the abutment and with its cylindrical bore surrounding the tapered shaft section. A tapered sleeve is interposed between the tapered shaft section of and the cylindrical roll bore. A circular retainer is axially received on and rotatably fixed with respect to the end section of the shaft. A nut is threaded onto the end section of the shaft to operate via the retainer to center the roll on the shaft by tightly inserting the sleeve between the tapered shaft section and the cylindrical roll bore. Screw members are threaded though the retainer into axial engagement with the outboard flank of the roll to urge the inboard flank of the roll against the abutment.
