Abstract: A joist assembly system that is structured for dynamic retrieval of components, dynamic and precise positioning and location of retrieved components, assembly of the components to form a joist, and delivery of the assembled joist. The joist assembly system has a plurality of material handling systems, a plurality of welding systems, and a rigging table system. The material handling systems are structured to load and position the components such as chords and webs onto the rigging table. The rigging table in turn supports the chords or webs. Subsequently, the plurality of welding systems weld the webs to the chords to form the joist.

Abstract: A combination of a bearing and a housing for the bearing is described, the combination comprising two substantially semi-cylindrical half bearings each retained in a corresponding housing part about a joint face split-line wherein the housing has at least one locking plate inserted in said joint face split-line, the at least one locking plate extending over the whole of the joint face area and extending radially inwardly to lie between opposed joint faces of the two bearing halves, at least one of the two bearing halves having a recess at the joint face to receive a projection on the locking plate.

Abstract: A combination of a bearing and a housing for the bearing is described, the bearing comprising two substantially semi-cylindrical half bearings each retained in a corresponding housing part about a joint face split-line wherein the housing has at least one circumferential locking plate inserted in said joint face split-line, said at least one circumferential locking plate extending radially inwardly to lie between opposed joint faces of the two bearing halves.

Abstract: A combination of a bearing and a housing for the bearing in an internal combustion engine as described, the bearing including two substantially semi-circular half-bearing shells comprising a first half-shell bearing having a first wall thickness and a second half-shell bearing having a second wall thickness wherein the first wall thickness is different from the second wall thickness and the first and second half-shells have a substantially common bore diameter when assembled in the housing.

Abstract: An explosive composition consisting of an explosive which contains an eleically conductive ingredient, and having a thermally conductive, electrically insulating substance incorporated therein in order to reduce the sensitivity of the composition to radio frequency.
