| 20120055218 | REGENERATIVE LAYING PIPE - A laying pipe configured for rotation about its axis in a rolling mill laying head, comprises a ferrous outer tube having an entry section aligned with its axis, an intermediate section curving away from its axis, and a delivery section having a constant radius measured from its axis. A ferrous inner tube has entry, intermediate and delivery sections respectively lining the entry, intermediate and delivery sections of the outer tube. The inner tube is constrained against movement relative to the outer tube solely by frictional contact with the outer tube. The inner tube is movable incrementally within the outer tube in one direction in response to heating and cooling cycles during rotation of the laying pipe about its axis. | 03-08-2012 |

| 20110148109 | LAYING HEAD PIPE CLAMP - A clamp assembly is disclosed for detachably retaining a curved laying pipe along the correspondingly curved edge of an auger support plate in a rolling mill laying head. The clamp assembly comprises a boss fixed to and projecting from the curved edge of the support plate. The boss has a first opening extending therethrough and an exterior support surface. A generally U-shaped clamp has a bridging web joining mutually spaced cheeks with second openings extending therethrough. The cheeks are configured and arranged to straddle the boss with their second openings in alignment with the first opening in the boss, and with the bridging web coacting with the exterior support surface of the boss to confine a segment of the laying pipe therebetween. A pin extends in an inserted position through the aligned first and second openings in the boss and the cheeks. | 06-23-2011 |
| 20110108652 | ROLLING MILL LAYING HEAD - A rolling mill laying head comprises a quill rotatable about a central axis. A guide pipe carried by the quill and is configured and arranged to form a longitudinally moving product into a continuous series of rings. Axially spaced bearings support the quill on a stationary support structure for rotation about its axis. At least one of the bearings comprises a hydrostatic oil film bearing. | 05-12-2011 |
| 20110108408 | VACUUM DEHYDRATOR - A vacuum dehydrator for processing an oil containing entrained contaminants such as water, air, and particulates comprises a tower enclosing upper and lower chambers. A random packing is contained in the upper chamber. The oil is preheated to a temperature above the boiling point of water and is introduced into the upper chamber for downward flow through the random packing into the lower chamber. Entrained air and water is retained as water vapor in the upper chamber, and particulates are retained in the random packing. Heated ambient air is introduced into the lower chamber for upward flow through the random packing into the upper chamber, and the upper chamber is cooled to condense the water vapor. Oil and condensed water are pumped respectively from the lower and upper chambers. | 05-12-2011 |
| 20110100082 | Side Looper - A side looper comprises an entry guide for directing a longitudinally moving long product into an arcuate path, an exit guide for receiving the product exiting from the arcuate path, and inner and outer guide walls arranged between the entry and exit guides. The guide walls are adjustable between mutually spaced closed positions fixing the curvature of the arcuate path, and open positions allowing the curvature of the arcuate path to either increase or decrease. | 05-05-2011 |
| 20110075956 | Sleeve for Oil Film Bearing - A sleeve is disclosed for use in an oil film bearing of the type employed to rotatably support the tapered neck of a roll in a rolling mill. The sleeve is machined from a hollow forging of a base metal with a cylindrical outer surface and a tapered inner surface adapted to be seated on the tapered roll neck. The tapered inner surface of the sleeve is coated with a layer of material that is chemically dissimilar with respect to the base metal. | 03-31-2011 |
| 20110048093 | Method of rolling feed products into different sized finished products - A feed product is rolled into different sized finished products in a rolling mill finishing section which comprises a plurality of modular rolling units arranged along the mill pass line. Each rolling unit includes two roll stands with work rolls configured to define successive oval and round roll passes. The roll stands are designed to effect specific area reductions on products rolled through their respective oval and round roll passes. Feed products having the same entry size are rolled into finished products having different reduced sizes by providing altered rolling sequences in which a selected rolling unit is replaced along the pass line with rolling units having roll stands designed to effect area reductions that differ from those of the roll stands of the replaced rolling unit. Rolling units downstream from the replaced rolling unit are removed from the pass line. The roll stands of rolling units upstream from the replaced rolling unit remain unchanged. | 03-03-2011 |
| 20110017577 | APPARATUS FOR LATERALLY TRANSFERRING BARS FROM A RECEIVING PATH TO A BRAKING PATH - An apparatus is disclosed for receiving successive bars moving longitudinally along an entry path and for laterally transferring the bars from the entry path to a braking path. The apparatus comprises a run in table having a plurality of rollers arranged to convey the bars along the entry path. A braking surface is arranged between the run in table and the braking path. The braking surface and the rollers of the run in table lie in a reference plane sloping downwardly from the entry path to the braking path. A dividing wall is arranged between the run in table and the braking surface. The dividing wall is adjustable between a raised position projecting above the reference plane to block lateral downward movement of bars from the entry path across the braking surface to the braking path, and a lowered position accommodating such downward movement. A switch is positioned in advance of the dividing wall. The switch has a plurality of guide channels arranged around a common axis. The switch is positioned to successively align individual guide channels with the entry path to thereby direct bars passing therethrough along the entry path while the dividing wall is in its raised position, and is rotatable about its axis to successively realign the individual guide channels with the braking path to thereby direct bars passing therethrough to and along the braking path when the dividing wall is in its lowered position. | 01-27-2011 |
| 20110017038 | Rotary Shear - A rotary shear for subdividing a product moving longitudinally along a path comprises a parallel pair of shafts having cutting blades connected thereto. The shafts are on opposite sides of and arranged symmetrically with respect to a center line of the shear. Driven gears on each of the shafts are spaced one from the other. A first pinion gear is in meshed relationship with one of the driven gears, and a second pinion gear in meshed relationship with the other of the driven gears. The first pinion gear has a diameter smaller than the diameter of the second pinion gear. The first and second pinion gears are in an intermeshed relationship at a location spaced laterally from the center line of the shear. | 01-27-2011 |
| 20090263231 | BUNDLING SYSTEM FOR LONG PRODUCTS - A system for bundling long ferrous products comprises a roller table for delivering the products longitudinally to a receiving station. A cradle is spaced laterally from the receiving station and is constructed and arranged to receive and accumulate the products in bundle form. A stacker is positioned between the receiving station and the cradle, and a pre-stacker is positioned between the stacker and the receiving station. A transport system laterally advances products from the receiving station to the pre-stacker, and the pre-stacker operates in concert with the transport system to pre-stack multiple layers of the products into sub-bundles and to transfer the sub-bundles to the stacker, which then operates to deposit the sub-bundles in the cradle. | 10-22-2009 |
