Abstract
Abstract A rotating drum or paddle like element carrying coalescer material exposed to the airstream in an aircraft water separator, exposes the face of the material to the upstream and downstream side of the airstream so that the air flow carries away the undesirable foreign matter collected by the coalescing material.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
173 words
A coalescer in combination with a water separator for aircraft air cycle airconditioning system which air contains foreign matter, a casing having an inlet and outlet, water separating means for centrifuging the heavy particles in the airstream out of the airstream in said casing, said coalescer in said casing between said inlet and outlet and upstream of said water separating means, said coalescer having coalescing material extending radially from an axis disposed transverse to said outlet in said casing and substantially continuously rotated about said axis so that the air flow from said inlet passes through said coalescing material depositing said foreign matter on the face of said coalescer material when facing said inlet before being admitted into said water separating means and said foreign matter being picked up from said coalescer material by the airstream when said face is rotated in a position to face said outlet whereby the foreign matter collected by the coalescer material is blown-off and discharged into the water separating means and separated out from said airstream thereby.
Claim 2
Dependent Claim
173 words
A coalescer in combination with a water separator for aircraft air cycle airconditioning system which air contains foreign matter, a casing having an inlet and outlet, water separating means for centrifuging the heavy particles in the airstream out of the airstream in said casing, said coalescer in said casing between said inlet and outlet and upstream of said water separating means, said coalescer having coalescing material extending radially from an axis disposed transverse to said outlet in said casing and substantially continuously rotated about said axis so that the air flow from said inlet passes through said coalescing material depositing said foreign matter on the face of said coalescer material when facing said inlet before being admitted into said water separating means and said foreign matter being picked up from said coalescer material by the airstream when said face is rotated in a position to face said outlet whereby the foreign matter collected by the coalescer material is blown-off and discharged into the water separating means and separated out from said airstream thereby.
Claim 3
Dependent Claim
30 words
A coalescer as claimed in claim 1 including a hub mounted in said casing on said axis, paddles supporting the coalescer material extending radially from and supported to said hub.
Claim 4
Dependent Claim
28 words
A coalescer as claimed in claim 2 including means for positioning said coalescer material so as to be bypassed whenever the pressure drop thereacross reaches a predetermined value.
Claim 5
Dependent Claim
40 words
A coalescer as claimed in claim 1 including a hub mounted in said casing on said axis, the coalescer material extending radially from said hub terminating in proximity to the inner wall of said casing and supported by said hub.
Claim 6
Dependent Claim
56 words
A coalescer as claimed in claim 1 including hub means mounted in said casing on said axis supporting said coalescing material, hinge means for supporting said coalescer material, and spring means preloading said coalescer material in an extended position so that said airstream collapses said coalescer material whenever the pressure drop thereacross reaches a predetermined value.
