Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
83 words
A packing for mass transfer, direct heat exchange or mixing comprising a plurality of vertically disposed parallel layers, each said layer having a plurality of inclined parallel deflecting surfaces and at least one bridge at one end of a layer connecting said deflecting surfaces of said respective layer together, said deflecting surfaces of one layer being disposed in criss-crossing relation to said deflecting surfaces of an adjacent layer to form criss-cross flow channels disposed in laterally open relationship from one layer to another.
Claim 2
Dependent Claim
83 words
A packing for mass transfer, direct heat exchange or mixing comprising a plurality of vertically disposed parallel layers, each said layer having a plurality of inclined parallel deflecting surfaces and at least one bridge at one end of a layer connecting said deflecting surfaces of said respective layer together, said deflecting surfaces of one layer being disposed in criss-crossing relation to said deflecting surfaces of an adjacent layer to form criss-cross flow channels disposed in laterally open relationship from one layer to another.
Claim 3
Dependent Claim
41 words
A packing as set forth in claim 1 wherein each layer has a bridge at each of two opposite ends connecting said deflecting surfaces thereof together, each said deflecting element being connected to said respective bridges at diagonally disposed corners thereof.
Claim 4
Dependent Claim
44 words
A packing as set forth in claim 1 wherein each layer has a bridge at each of two opposite ends connecting said deflecting surfaces thereof together, each said deflecting element being connected to said respective bridges at opposite ends of a longitudinal side thereof.
Claim 5
Dependent Claim
41 words
A packing as set forth in claim 1 wherein each deflecting surface includes at least two spaced apart sections, and which comprises at least three bridges with each deflecting surface section being connected at opposite ends to two of said bridges.
Claim 6
Dependent Claim
23 words
A packing as set forth in claim 4 wherein said sections of each deflecting element are disposed in angular relation of each other.
Claim 7
Dependent Claim
27 words
A packing as set forth in claim 1 wherein at least one side of each deflecting surface and/or said bridge is jagged on an outer edge thereof.
Claim 8
Dependent Claim
19 words
A packing as set forth in claim 1 wherein said bridges of adjacent layers are interconnected to each other.
Claim 9
Dependent Claim
22 words
A packing as set forth in claim 1 wherein said deflecting surfaces of each layer extend from opposite sides of said bridge.
Claim 10
Dependent Claim
26 words
A packing as set forth in claim 1 wherein two neighboring deflecting surfaces of said layers extend from opposite sides of said bridges and are coplanar.
Claim 11
Dependent Claim
34 words
A packing as set forth in claim 1 wherein each layer has a plurality of parallel strips extending from said bridge in co-planar relation with each deflecting surface extending outwardly of a respective strip.
