Abstract: A stator vane arrangement for a turbomachine comprises a radially inner annular structure, a radially outer annular structure and a plurality of circumferentially spaced vanes extending radially between the inner annular structure and the outer annular structure. At least one of the vanes has a passage extending from the inner annular structure to the outer annular structure. The inner annular structure has at least one radially inwardly extending boss and each boss has a passage extending there-through. The passage in each boss is aligned with a corresponding passage in a vane. Each boss comprises a first portion having a first cross-sectional area and a second portion having a second cross-sectional area which is greater than the first cross-sectional area. The first portion of each boss is positioned between and interconnecting the second portion of the boss and the inner annular structure.

Abstract: The disclosed picture stabilizing system detects and measures picture unsteadiness in recorded or live video caused by an unsteady television camera and automatically eliminates the unsteadiness without destroying intentional panning and tilting of the camera. This is accomplished by selecting camera motion references within the camera field of view consisting of one horizontal edge and one vertical edge of an object which will normally be stationary, such as a door, a window, or a piece of furniture. The stabilizer "locks" onto these edges, continually measuring their motion from field to field and utilizing a frame store, makes the necessary vertical and horizontal corrections to the overall picture to eliminate such motion. The system is able to correct for movement due to random unsteadiness without interfering with planned camera movement.
