Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
215 words
An air terminal comprising: a primary chamber adapted for connection to a source of conditioned air; an air distribution chamber associated with said primary chamber; a distribution plate disposed between said primary chAmber and said distribution chamber, said distribution plate having a plurality of openings formed therein for passage of conditioned air from said primary chamber into said air distribution chamber. a downwardly projecting wall member associated with said distribution chamber; a downwardly projecting convex plate member disposed opposite said wall member; sound-absorbing material disposed on said downwardly projecting wall member opposite said downwardly projecting plate member so as to form a passage between said plate member and said soundabsorbing material, the upper portion of said passage having a decreasing cross-sectional area in the direction of air flow and the lower portion of said passage having an increasing cross-sectional area in the direction of air flow to dissipate sound energy within said passage, said plate member having a generally concave recess formed therein; an inflatable bladder disposed within said recess, the outer surface of said bladder residing substantially flush with the surface of said downwardly projecting plate member when said bladder is deflated; and a cutoff plate disposed opposite said bladder for cooperation therewith to restrict flow of air therebetween when said bladder is inflated.
Claim 2
Dependent Claim
215 words
An air terminal comprising: a primary chamber adapted for connection to a source of conditioned air; an air distribution chamber associated with said primary chamber; a distribution plate disposed between said primary chAmber and said distribution chamber, said distribution plate having a plurality of openings formed therein for passage of conditioned air from said primary chamber into said air distribution chamber. a downwardly projecting wall member associated with said distribution chamber; a downwardly projecting convex plate member disposed opposite said wall member; sound-absorbing material disposed on said downwardly projecting wall member opposite said downwardly projecting plate member so as to form a passage between said plate member and said soundabsorbing material, the upper portion of said passage having a decreasing cross-sectional area in the direction of air flow and the lower portion of said passage having an increasing cross-sectional area in the direction of air flow to dissipate sound energy within said passage, said plate member having a generally concave recess formed therein; an inflatable bladder disposed within said recess, the outer surface of said bladder residing substantially flush with the surface of said downwardly projecting plate member when said bladder is deflated; and a cutoff plate disposed opposite said bladder for cooperation therewith to restrict flow of air therebetween when said bladder is inflated.
Claim 3
Dependent Claim
152 words
An air terminal comprising: a primary chamber adapted for connection to a source of conditioned air; an air distribution chamber associated with said primary chamber; a distribution plate disposed between said primary chamber and said distribution chamber, said distribution plate having a plurality of openings formed therein for passage of conditioned air from said primary chamber into said air distribution chamber; a downwardly projecting wall member associated with said distribution chamber; a downwardly projecting plate member disposed opposite said wall member to form a space therebetween for passage of air therethrough from said distribution chamber, said plate member having a generally concave recess formed therein; an inflatable bladder having a generally V-shaped configuration disposed within said recess, the outer surface of said bladder assuming a generally concave configuration when deflated; and a cutoff plate disposed opposite said bladder for cooperation therewith to restrict flow of air therebetween when said bladder is inflated.
Claim 4
Dependent Claim
152 words
An air terminal comprising: a primary chamber adapted for connection to a source of conditioned air; an air distribution chamber associated with said primary chamber; a distribution plate disposed between said primary chamber and said distribution chamber, said distribution plate having a plurality of openings formed therein for passage of conditioned air from said primary chamber into said air distribution chamber; a downwardly projecting wall member associated with said distribution chamber; a downwardly projecting plate member disposed opposite said wall member to form a space therebetween for passage of air therethrough from said distribution chamber, said plate member having a generally concave recess formed therein; an inflatable bladder having a generally V-shaped configuration disposed within said recess, the outer surface of said bladder assuming a generally concave configuration when deflated; and a cutoff plate disposed opposite said bladder for cooperation therewith to restrict flow of air therebetween when said bladder is inflated.
Claim 5
Dependent Claim
190 words
An air terminal according to claim 1 further including: a second downwardly projecting wall member associated with said distribution chamber, said second downwardly projecting wall member having sound-absorbing material disposed thereon; a second downwardly projecting convex plate member associated with said first downwardly projecting convex plate member to form a partition therewith between said sound-absorbing material on said wall members to form two spaces therebetween for passage of air therethrough from said distribution chamber, the upper portion of said passages having a decreasing cross-sectional area in the direction of air flow and the lower portion of said passages having an increasing cross-sectional area in the direction of air flow to dissipate sound energy within said passage, said second plate member having a generally concave recess formed therein: a second inflatable bladder disposed within the recess in said second downwardly projecting plate member, the outer surface of said second bladder residing substantially flush with the surface of second downwardly projecting plate member when said bladder is deflated; and a second cutoff plate disposed opposite said second bladder for cooperation therewith to restrict flow of air therebetween when said bladder is inflated.
Claim 6
Dependent Claim
128 words
An air terminal according to claim 2 further including: a second downwardly projecting wall member associated with said distribution chamber; a second downwardly projecting plate member associated with said first downwardly projecting plate member to form a partition therewith between said wall members to form two spaces theRebetween for passage of air therethrough from said distribution chamber, said second downwardly projecting plate member having a generally concave recess formed therein; a second inflatable bladder having a generally V-shaped configuration disposed within the recess of said second downwardly projecting plate member, the outer surface of said second bladder assuming a generally concave configuration when deflated; and a second cutoff plate disposed opposite said second bladder for cooperation therewith to restrict flow of air therebetween when said bladder is inflated.
