Abstract: Apparatuses are provided for reducing noise generation from a dead ended conduit in a gas turbine engine. In particular A scooped bellmouth is provided that comprises a bellmouth within a surface having an outer perimeter an inner perimeter and a ramp diverging from the surface at a first end, the ramp extending radially through the outer perimeter of the bellmouth at a second end. The ramp diverts an airflow away from the bellmouth thereby preventing the development of a low pressure area at the bellmouth without affecting the efficiency of the gas turbine engine.

Abstract: An adjustment plate (10) is used for holding a fixture plate (12) adjustably on a grinder table (14). The adjustment plate (10) includes a shoulder bolt (30) that passes through the fixture plate (12) and threadably engages the adjustment plate (10). The adjustment plate (10) further includes a toggle bolt assembly (50) attached to the base of the adjustment plate to engage the fixture plate (12). The shoulder bolt (30) and the toggle bolt (50) allow the fixture plate (12) to be adjusted about the vertical axis of the adjustment plate (10). The adjustment plate (10) further includes a clamp (32) that is used to clamp the fixture plate (12) to the adjustment plate (10) when the fixture plate (12) is properly positioned. The adjustment plate (10) is attached to the grinder table (14) by a plurality of T-bolts (64) slidably received in T-bolt holes (70) in adjustment plate (10). A plurality of set screws (80) are threadably received in adjustment plate (10) and each engage the grinder table (14).
