Plural spreaders interconnect the first and second border members thereby defining an airflow aperture therebetween. A pattern controller is slidably disposed between the plural spreaders for controlling the volume of airflow through the airflow aperture. The pattern controller is pivotable within the airflow aperture for controlling the direction of airflow through the airflow aperture.

Abstract: A slot-shaped outlet having first flow guide means extending in the interior space of a flow chamber. The flow guide means are extensions of the parallel arranged longitudinal side flanks that extend from the outside to the inside of the slot outlet. The flow guide means are first parallel with each other, and subsequently extend in a curved manner, diverging from each other, with their free longitudinal edges resting closely against the inner surface of the flow chamber. There are second flow guide means arranged parallel with each other between the longitudinal side flanks. The second flow guide means extend transversely in relation to the longitudinal direction.

Abstract: Passenger cabin ventilation air outlets located in the cabin ceiling blow air downward toward the passengers. An outlet for this location utilizes a series of high velocity jets exiting from a narrow ceiling nozzle to entrain cabin air to form a broad slow moving single jet. Three rows of slots are utilized, the outer rows to initially produce a wide air jet, and the center row to draw the outer jets back together outside of the nozzle. The center jets coalesce the outer jets into a slower moving total air stream.

Abstract: A slot diffuser includes a pair of elongate and parallel side walls spaced by pairs of bridges. The bridges include feet that slide along receivers in the side walls such that the bridges can be positioned at any location therealong and provide support to the bridges and stability to the diffuser. The bridges include slots that extend between the side rails and that receive ends of air flow control blades. The air flow control blades have an elongate planar portion supported by rods extending outwardly on either side of the planar portions to support the blades in the slots. The blades are removable without disassembling the entire diffuser. Each bridge has an arcuate cover that reduces air drag and each bridge also has a low profile to further reduce air drag and thus reduce noise produced by the diffuser.
