Abstract: An air baffle assembly for air cooling in computer systems is described. The air baffle assembly can include a baffle body removably installed on a printed circuit assembly deployed on a chassis. The baffle body can cover memory components. The air baffle assembly can also include an air dam removably installed on the baffle body. The baffle body has a slot positioned on a side of the baffle body, which can be substantially parallel to a wall of the chassis. The baffle body can further include alignment rails positioned in the slot to guide installation of the air dam into the slot. The installed air dam can reduce a bypass region, thereby reducing airflow through the bypass region and increasing airflow through the memory components.

Abstract: The present invention provides an improvement for a wind turbine (20) having at least one blade (21) mounted on a hub (22) for controlled rotation about a blade axis (yb-yb) to vary the pitch of the blade relative to an airstream. The hub is mounted on a nacelle (23) for rotation about a hub axis (xh-xh). The wind turbine includes a main pitch control system for selectively controlling the pitch of the blade, and/or a safety pitch control system for overriding the main blade pitch control system and for causing the blade to move toward a feathered position in the event of an overspeed or fault condition.
