Abstract: A modular rolling mill comprises a plurality of rolling units having work rolls configured and arranged to progressively reduce the cross sectional area of a product received along a mill pass line. Gear units are mechanically coupled to each rolling unit, with each gear unit in turn being mechanically coupled to a driven line shaft by first bevel gear sets. The ratios of the first bevel gear sets progressively increase from the first to the last of the gear units to thereby accommodate a progressively increasing speed of the product being rolled. A second bevel gear set is associated with the last gear unit. The ratio of the second bevel gear set is the same as the ratio of the first level gear set of the penultimate gear unit. The line shaft is selectively coupled to the last gear unit via one or the other of its first and second bevel gear sets.

Abstract: A method is disclosed for controlling the speed of a curved rotatably driven laying pipe through which a longitudinally moving product is directed to exit from the delivery end of the pipe as a helical formation of rings. The method comprises determining the maximum and minimum internal radii Rmax, Rmin of the pipe at the location of the maximum radius R of the pipe as measured from its rotational axis; continuously measuring the velocity Vp of the product entering the laying pipe; and, controlling the rotational speed of the laying pipe such that the rotational velocities Vmax, Vmin of the pipe at said maximum and minimum internal radii bracket a range containing the velocity Vp of the product.

Abstract: A system and method to detect row-to-row shorts and other row decode defects in memory devices and other electronic devices having a similar data storage functionality is disclosed. A selective switching between a normal large pull-up device and a smaller one in a wordline driver path allows limiting the current in the pull-up circuit to a low value so as to detect shorts because the shorts will cause the active wordline voltage level to drop, while a wordline without shorts will operate well. A GIDL (Gate Induced Drain Leakage) reduction circuit may be used as a pull-up circuit connected to supply a bias voltage to the wordline driver associated with a wordline being tested for shorts or other defects. A test signal may be selectively generated during testing so as to supply a lower strength voltage output of the GIDL circuit (the VccpRDec output) as the bias voltage to the wordline driver.

Abstract: A transport path is defined by a plurality of consecutively arranged separately driven conveyor sections. A plurality of heat treating stations are spaced one from the other along the transport path. Coils are conveyed along the transport path through one or more of the heat treating stations. The speed at which the coils are conveyed on the separately driven conveyor sections is controlled to provide different transport and/or dwell times for the coils at different locations along the transport path.

Abstract: A memory array is provided, having at least two memory cells accessed for each row address to retain a sufficient electric charge to properly store “1” and “0” bits. For such a memory array, both even and odd row decoders in the array are permanently enabled so that each row address the array receives causes the even row decoder to energize at least one even word line and the odd row decoder to energize at least one odd word line. As a result, at least two memory cells are accessed for each row address so that each “1” or “0” bit is stored as an electric charge in at least two memory cells.

Abstract: Accumulators are interposed between an initial mill section having an elevated first production rate and each of a plurality of different outlet mill sections having lower second production rates. Each accumulator is constructed and arranged to receive intermediate products from the initial mill section at its elevated first production rate, and to deliver the intermediate products to the associated outlet mill section at its respective lower second production rate. The excess intermediate product resulting from the differential between the first and second production rates is stored temporarily in the accumulator. Switches direct successive intermediate product lengths from the initial mill section to selected outlet mill sections via their respective accumulators for simultaneous processing into packaged finished products.

Abstract: A modular rolling mill comprises a plurality of separate rolling units arranged along a mill pass line. Each rolling unit includes at least two pairs of work rolls defining oval and round roll passes and carried on roll shafts that are staggered 90° with respect to each other. The rolling units contain intermediate drive trains configured to connect the roll shafts to parallel input shafts projecting to a first side of the pass line from the respective rolling units. A single driven line shaft is parallel to and on the first side of the pass line. Output shafts are mechanically coupled to the line shaft by bevel gear sets. The output shafts project laterally from the line shaft towards the pass line and are connected by separable couplings to the input shafts of the rolling units.

Abstract: In a system for subdividing hot rolled product lengths being delivered from a rolling mill along a first path, a first switch acts in concert with a first shear to subdivide each product length traveling along the first path into successive segments including a front end segment, a plurality of intermediate segments, and a tail end segment, and to alternately deliver the successive segments to one or the other of two adjacent downstream second paths leading to a cooling bed. Second switches on the second paths are selectively adjustable between first positions allowing the intermediate segments to continue along the second paths, and second positions diverting the front and tail end segments from the second paths to third paths. A second shear chops the front and tail end segments moving along the third paths into scrap pieces.
