Abstract:
A dragline bucket includes a bottom wall, a pair of sidewalls and a rear wall that collectively define a cavity. The sidewalls each have a large downward taper of at least about 7 degrees in at least its forward area. In an alternative embodiment, the sidewalls each have an upward taper in its rearward area which alleviates the need for a spreader bar. The dragline bucket collects earthen material with minimal disruption of the material.

Abstract:
A method and apparatus are described for the casting of a composite metal ingot having two or more separately formed layers of one or more alloys. An open ended annular mould is provided having a divider wall dividing a feed end of the mould into at least two separate feed chambers. For each pair of adjacent feed chambers, a first alloy stream is fed through one of the pair of feed chambers into the mould and a second alloy stream is fed through another of the feed chambers. A self-supporting surface is generated on the surface of the first alloy stream and the second alloy stream is contacted with the first stream. By carefully selecting conditions and positions where the alloy streams meet, a composite metal ingot is formed in which the alloy layers are mutually attached with a substantially continuous metallurgical bond.

Abstract:
A socket and wedge assembly that securely holds wire rope and is easy to release includes a collapsible wedge. The wedge collapses at the front, narrowed end to utilize the high pressures at the front end of the wedge in effecting the collapse and releasing the rope. The wedge includes a movable element that pivots and/or translates to facilitate a quick and reliable collapse of the wedge and release of the wire rope. The wedge includes a cavity to at least partially exhaust the fumes created from cutting the support with a torch for release of the wire rope.

Abstract:
A composite metal ingot having two or more lengthwise alloy layers including adjacent first and second layers respectively formed of an aluminum-manganese alloy and an aluminum alloy of a different composition wherein the interface between the first and second layers is in the form of a substantially continuous metallurgical bond characterized by the presence of particles of one or more intermetallic compositions containing manganese from the first layer dispersed within a region of the second layer adjacent the interface, the first and second layers having been formed by applying the alloy for the second layer to a self-supporting surface of the first layer while the self-supporting surface is at a temperature between the solidus and liquidus temperatures of the first layer alloy.

Abstract:
A method and apparatus are described for the casting of a composite metal ingot comprising at least two separately formed layers of one or more alloys. An open ended annular mould has a feed end and an exit end and divider wall for dividing the feed end into at least two separate feed chambers, where each feed chamber is adjacent at least one other feed chamber. For each pair of adjacent feed chambers a first alloy stream is fed through one of the pair of feed chambers into the mould and a second alloy stream is fed through another of the feed chambers. A self-supporting surface is generated on the surface of the first alloy stream and the second alloy stream is contacted with the first stream such that the upper surface of the second alloy stream is maintained at a position such that it first contacts the self-supporting surface where the self-supporting surface temperature is between the liquidus and solidus temperatures of the first alloy or it first contacts the self-supporting surface where the self-supporting surface temperature is below the solidus temperatures of the first alloy but the interface between the two alloys is then reheated to between the liquidus and solidus temperatures, whereby the two alloy streams are joined as two layers. The joined alloy layers are then cooled to form a composite ingot. This composite ingot has a substantially continuous metallurgical bond between alloy layers with dispersed particles of one or more intermetallic compositions of the first alloy in a region of the second alloy adjacent the interface.

The joined alloy layers are then cooled to form a composite ingot. This composite ingot has a substantially continuous metallurgical bond between alloy layers with dispersed particles of one or more intermetallic compositions of the first alloy in a region of the second alloy adjacent the interface. The combination of an alloy of high strength bonded to a surface layer of higher ductility gives a sheet of improved bendability compared to the high strength alloy used alone.
