Abstract: A method for manufacturing, transporting, and installing an extruded aluminum roof truss by manufacturing an extrusion that comprises a top chord extrusion, a bottom chord extrusion, a web brace extrusion, manufacturing standardized components such as a connector, a hinge, a bracket, and a fastener used to configure the extrusion into a truss configuration, pre-assembling the extrusion with an optionally pre-determined set of the standardized components required to either fully or partially assemble the truss prior to transport and installation at the building site, transporting the truss in either a fully or partially assembled compact configuration to the installation site, rotating the truss open by pivoting the web bracing into alignment with a matching connector hole on an extrusion at the installation site, and installing any required connectors or remaining standardized components to complete the truss.

Abstract: A system and method for manufacturing, assembling, and installing an extruded aluminum wall panel frame by manufacturing an extrusion profile that comprises a stud, a sole plate, and a sill plate and other components used to configure the extrusion profile into a frame either fully or partially assembled prior to transport and installation at the building site where the frame may be installed as a single-level structure or multi-level structure of varying lengths, widths, and floorplans.

Abstract: A pedestal extends upwardly from the body of a gate valve housing in a straddling relationship to the gate. An operator, detachably attachable to the pedestal, includes a hand wheel operating through a pinion gear to impart translatory movement to a vertically oriented rack. A clevis is disposed at the lower extremity of the rack for attachment through a pin to the upper end of the gate. A removable pin is employed to secure the gate, in either a raised or a lowered position, to the pedestal and to maintain the gate in position after removal of the operator.

Abstract: A replaceable one piece bore and chest liner is enclosed within a pair of mirror image castings to define a gate valve. A cast gate, enveloped within molded material, cooperates with the liner to open and close the gate valve.

Abstract: A selectively biased seal for a gate, which gate is translatable within a one piece liner of a gate valve, is disclosed. Lever means for operating the gate and oriented with or normal to the direction of flow through the gate valve are also described.
