Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
132 words
An apparatus supplying conditioned air into an enclosure comprising: a. a terminal air discharge unit adapted for installation in an opening in a wall of the enclosure; b. a plenum for supplying primary air to said terminal unit; c. means in said wall for supplying secondary air from a space above the enclosure to said terminal unit for intermixture with and to temper the primary air discharged from said terminal unit; d. said terminal unit comprising an outwardly flaring member and a baffle member defining a discharge nozzle; e. said flaring member being apertured to admit secondary air into said discharge nozzle, and f. a divider member displaceable in said discharge nozzle relative to the said apertured member to regulate the proportion of primary air and secondary air discharged into the enclosure.
Claim 2
Independent Claim
132 words
An apparatus supplying conditioned air into an enclosure comprising: a. a terminal air discharge unit adapted for installation in an opening in a wall of the enclosure; b. a plenum for supplying primary air to said terminal unit; c. means in said wall for supplying secondary air from a space above the enclosure to said terminal unit for intermixture with and to temper the primary air discharged from said terminal unit; d. said terminal unit comprising an outwardly flaring member and a baffle member defining a discharge nozzle; e. said flaring member being apertured to admit secondary air into said discharge nozzle, and f. a divider member displaceable in said discharge nozzle relative to the said apertured member to regulate the proportion of primary air and secondary air discharged into the enclosure.
Claim 3
Dependent Claim
32 words
The apparatus of claim 1 in which the divider is mounted for movement between end positions in one of which the whole area of the aperture is in communication with the plenum.
Claim 4
Dependent Claim
14 words
The apparatus of claim 1 in which the divider is mounted for pivotal movement.
Claim 5
Dependent Claim
16 words
The apparatus of claim 1 in which the divider is mounted for movement parallel to itself.
Claim 6
Dependent Claim
143 words
In apparatus for conditioning the air in an enclosed space, a terminal unit comprising: a frame adapted to be mounted over an opening in a boundary of the space, an aperture in the frame to register with the opening, a flared skirt forming part of the frame, the free edge of which defines the outer edge of the aperture, an orifice in the skirt, and a plenum, for primary air, mounted on the frame and in communication with the aperture in the frame, characterized by: a divider movable within the aperture to proportion flow of air through the aperture of primary air from inside the plenum and secondary air from outside it, and means to adjust the divider; the divider being flared complementally to the skirt and being parallel with the skirt, and being so movable as to remain parallel with the skirt.
Claim 7
Dependent Claim
143 words
In apparatus for conditioning the air in an enclosed space, a terminal unit comprising: a frame adapted to be mounted over an opening in a boundary of the space, an aperture in the frame to register with the opening, a flared skirt forming part of the frame, the free edge of which defines the outer edge of the aperture, an orifice in the skirt, and a plenum, for primary air, mounted on the frame and in communication with the aperture in the frame, characterized by: a divider movable within the aperture to proportion flow of air through the aperture of primary air from inside the plenum and secondary air from outside it, and means to adjust the divider; the divider being flared complementally to the skirt and being parallel with the skirt, and being so movable as to remain parallel with the skirt.
Claim 8
Dependent Claim
50 words
The unit of claim 5 in which the flared skirt and the flared divider are respectively constituted by a first truncated cone and a second truncated cone arranged concentrically with the first truncated cone, the second cone being movable vertically along its axis towards and away from the first cone.
Claim 9
Dependent Claim
13 words
The unit of claim 5 in which the barrier is horizontal and circular.
Claim 10
Dependent Claim
28 words
The unit of claim 5 including a planar barrier that is part of the frame and the peripheral edge of which defines the inner edge of the aperture.
