A system and method for loading railcars of a train wherein the railcars are provided with upper lids having latches for securing the lids in a closed position. The system comprises at least one sensing system for determining the position of the latches and the lids in order for one or more robot arms to perform operations such as unlatching, latching, lid opening and lid closing. At least one velocity sensor measures individual railcar velocity rather than overall train speed to enable engagement of the one or more robotic arms, as adjacent railcars may move at differing velocities due to slack in the connections between them.

An apparatus for actively transferring a coil of hot metal within a coilbox in hot strip mill. The apparatus is located downstream of the initial coilbox uncoiling station and includes at least one singly pivoting coil cradle. Such a coil cradle has a first support roller with a fixed rotational axis, a swing-frame mounted to pivot about that axis, and a second support roller mounted to the swing-frame, able to pivot about the fixed rotational axis of the first support roller to permit the coil of hot metal to be passed from the coil cradle. In certain embodiments, the apparatus includes a plurality of such singly pivoting coil cradles. The apparatus may also include at least one dually pivoting coil cradle.

An anchoring system for semisubmersible drill rigs is described which includes a wire rope-chain cable anchor line and in which system components co-operate to convey the junction of the wire rope and chain cable smoothly over a fairlead sheave. The connector joining the anchor line has a narrow end in which the rope is rigidly retained, a large end at which a chain end link is pivotally retained, and a radially symmetric, generally concave surface extending between the two connector ends. The outer surface of the connector is shaped to seat against the central hub of the fairlead sheave in a predetermined orientation in which a limited fixed bend angle is formed between the connector and the wire rope. The geometry of the connector naturally biases the connector to seat against the central hub of the fairlead sheave in the predeterminted orientation during hauling in of the anchor line. A collar fitted about the penultimate chain link displaces the large connector end from the sheave during paying out of the anchor line until the outer connector surface can be drawn by the wire rope into engagement with the sheave. Wire rope bending is accordingly minimized without significantly enlarging or altering the size of the fairlead sheave.
