Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
112 words
An apparatus for diffusing flowing quench air at the exhaust of said air from a quench stack for cooling moving synthetic melt-spun fibers, said stack having an exhaust outlet in an exhaust portion of said stack, comprising a series of slats arranged peripherally between said fibers and said quench stack in said exhaust portion, said slats being spaced apart to each other and form a plurality of gaps between said slats varying in width, said variation in width of said gaps being wider around the circumference nearer said air exhaust outlet of said quench stack and correspondingly being narrower around the circumference away from said air exhaust outlet of said quench stack.
Claim 2
Independent Claim
112 words
An apparatus for diffusing flowing quench air at the exhaust of said air from a quench stack for cooling moving synthetic melt-spun fibers, said stack having an exhaust outlet in an exhaust portion of said stack, comprising a series of slats arranged peripherally between said fibers and said quench stack in said exhaust portion, said slats being spaced apart to each other and form a plurality of gaps between said slats varying in width, said variation in width of said gaps being wider around the circumference nearer said air exhaust outlet of said quench stack and correspondingly being narrower around the circumference away from said air exhaust outlet of said quench stack.
Claim 3
Dependent Claim
10 words
The apparatus of claim 1 wherein said slats are tapered.
Claim 4
Dependent Claim
26 words
The apparatus of claim 1 wherein said slats are arranged peripherally parallel to the flow of said quench air and said fibers in said quench stack.
Claim 5
Dependent Claim
26 words
The apparatus of claim 2 wherein said slats are arranged peripherally parallel to the flow of said quench air and said fibers in said quench stack.
Claim 6
Dependent Claim
18 words
The apparatus of claim 4 wherein said slats are tapered to have gaps narrower toward said air flow.
