Abstract: A metal truss comprises elongated top chord members connected to each other at their ends. A first elongated bottom chord member is connected at its ends to the top chord members adjacent the free ends of the top chord members. A second elongated bottom chord member is connected at its ends to the top chord members, or directly to the first bottom chord member via spacers, such that the second bottom chord member is spaced below the first bottom chord member. At least one web member is positioned between and interconnecting at least one top chord member and the first bottom chord member. One end of the web member is connected to the at least one top chord member and the other end of the web member is connected to the first bottom chord member.

Abstract: A method for when preheating a ladle for use in steelmaking where less fuel is consumed in heating the ladle efficiently accurately to a controlled temperature. A temperature of a preheating process is varied by controlling a burner of the heating unit based on measurements of refractories of the ladle taken by a pyrometer. The heating unit includes an emissive coating for reducing heat loss and efficient heating during the preheating process. The heating unit also includes valve mechanisms for accurately varying a flame size of the burner of the heating unit during an idle stage of the preheating process.

Abstract: A rigging table and methods and systems for assembling trusses using a rigging table. An embodiment of a rigging table includes a base having a generally longitudinal axis and a generally lateral extent, and at least two bunk assemblies movable along the base in at least the generally longitudinal axis such that each bunk assembly is capable of being positioned on the base relative to another bunk assembly. Each bunk assembly may include a frame extending along the lateral extent of the base, a pair of guides slideably positioned on the frame to move generally transverse to the longitudinal axis of the base toward and away from each other and able to be fastened in position on the frame, and a pair of automated clamp members each positioned relative to and movable with one of the guides on the frame, to accommodate assembly of different sized trusses.

Abstract: A coating apparatus and method of using for use in dip coating an article may have a container with opposing sides and a volume capable of holding a liquid coating material and at least one article to be coated by the material, and a stepped apron adjacent at least one of the opposing sides of the container, the stepped apron capable of holding the liquid coating material to a depth sufficient to maintain the material in the liquid state and receiving the liquid coating material dripping from at least one coated article positioned above the stepped apron; and at least one support member above the container capable of holding at least one article to be coated by dipping in the container. The apparatus may include localized heating of the article, such as by spot welding, and air cooling of the article using a cooling system having at least one fan and a conveyor before the article is dipped in the container containing the liquid coating material and subsequently dried.

Abstract: Embodiments of the present invention are directed to methods, systems and computer program products for identifying fraudulent transactions. In general, transaction information is inputted into the system and an address is received from such information. A database is then queried to determine if the address already exists in the database. A determination is made whether or not the transaction is suspicious in response to the address existing in the database entry. Alternatively, in response to the address not existing in the database entry, a determination is made as to whether or not the transaction is suspicious based on a geocode. A geocode is a geographic location or coordinates of an address.

Abstract: Systems are provided for use in balcony structures. The system includes a joist comprising an upper chord and a lower chord separated by a web. One end of the joist is supported by a supporting member and a cantilevered balcony extends generally perpendicularly from the supporting member. The cantilevered balcony comprises a cementitious balcony slab extending from a cementitious floor slab. The cementitious floor slab includes a backspan region extending from the top of the supporting member opposite the cementitious balcony slab. A portion of the joist in the backspan region comprises a decking supporting member coupled to the web between the upper chord and the lower chord. The joist in the backspan region supports decking using the decking supporting member; however, the joist beyond the backspan region supports decking above the upper chord. In this way, the cementitious floor slab in the backspan region is thicker than the cementitious floor slab beyond the backspan region.
