Abstract: A welding assembly is disclosed. The welding assembly includes a plurality of separately controllable actuators (e.g., pneumatic, having an axially movable ram) to press a corresponding portion of a first workpiece (e.g., a discrete flange of a first stiffener) against a second workpiece (e.g., an outer skin) for welding operations (e.g., via induction welding).

Abstract: Furnace furniture (10) comprising a modular assembly of cast link parts (20) arrayed in rows and cast connector parts (30) mechanically connecting the cast link parts (20) together. The metal for the cast parts can be formulated to accommodate particular thermal-treatment circumstances. And the modular assembly method allows the fabrication of many furnace-furniture designs from a standard inventory of cast metal parts.

Abstract: A cooktop has a recessed portion surrounding a burner opening. The recessed portion includes bosses with grate supporting surfaces below the upper surface of the cooktop, and dams with vertical inner surfaces. A grate has a rectangular base with a vertical side wall and a bottom edge. The grate is mounted in the recessed portion, aligned with the burner opening, with the base bottom edge resting on the grate supporting surfaces of the bosses and with the grate side wall adjacent the vertical inner surfaces of the dams. The base includes tabs aligned with the dams and extending downwardly to provide greater height at the portions of the side wall aligned with the dams.
