Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
A ceiling air terminal for use in an air-conditioning and distributing system for discharging air into a space to be conditioned comprising: a primary chamber adapted for connection to a source of conditioned air; opposed, parallel walls, associated with said primary chamber to form an air discharge slot, each of said walls having a curved end portion having a radius R; diffuser means disposed within said slot and held in fixed relation to said curved end portion of each of said walls to produce two discharge air streams which will attach to the ceiling adjacent said terminal, said diffuser means having first and second upper walls disposed at an angle in the range 0* to 45* from horizontal, said walls being spaced a distance b from the curved end portions of said opposed walls to provide a b/R ratio having a lower limit of .10, the upper limit of the b/R ratio varying inversely from .70 to .25 as the diffuser wall angle varies from 0* to 45*.
Claim 2
Dependent Claim
168 words
A ceiling air terminal for use in an air-conditioning and distributing system for discharging air into a space to be conditioned comprising: a primary chamber adapted for connection to a source of conditioned air; opposed, parallel walls, associated with said primary chamber to form an air discharge slot, each of said walls having a curved end portion having a radius R; diffuser means disposed within said slot and held in fixed relation to said curved end portion of each of said walls to produce two discharge air streams which will attach to the ceiling adjacent said terminal, said diffuser means having first and second upper walls disposed at an angle in the range 0* to 45* from horizontal, said walls being spaced a distance b from the curved end portions of said opposed walls to provide a b/R ratio having a lower limit of .10, the upper limit of the b/R ratio varying inversely from .70 to .25 as the diffuser wall angle varies from 0* to 45*.
Claim 3
Dependent Claim
53 words
An air terminal according to claim 1 including an air distribution chamber associated with said primary chamber; and 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 distribution chamber.
Claim 4
Dependent Claim
67 words
An air terminal according to claim 2 further including means associated with said distribution chamber for regulating the quantity of air discharged from said distribution chamber, said means including an inflatable bladder; and a cutoff plate disposed opposite said bladder for cooperation therewith, inflation of said bladder reducing the area between said bladder and said cutoff plate to reduce the quantity of air discharged from the terminal.
Claim 5
Dependent Claim
60 words
An air terminal according to claim 1 wherein said diffuser means is triangularly shaped, the upper walls of said diffuser means is triangle being disposed at an angle of 20* from the base of said triangle, said triangular walls being spaced a distance b from the curved end portions of said opposed walls to provide a b/R ratio of .375.
