Abstract
Abstract A fluid transmitting element, particularly for increasing vapor-liquid contact, comprises a continuously open element which is resiliently deformable to open still farther under the pressure of a fluid stream. The element is a plate or tray which comprises a fluid barrier, and has a plurality of resilient interfingering strips. Means are provided which permit opening of the element in only one direction.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
86 words
A fluid transmitting element for increasing vapor-liquid contact, said element having at least one flow opening therethrough, and a flow control member disposed in said opening, said flow control member comprising a resilient flat metal plate having a plurality of interfingering strips integral therewith, said strips being coplanar with each other and with said plate and spaced apart in their undeformed condition and defining between them a zigzag slot, said strips on each side of said slot having the configuration of a straight series of sawteeth.
Claim 2
Dependent Claim
86 words
A fluid transmitting element for increasing vapor-liquid contact, said element having at least one flow opening therethrough, and a flow control member disposed in said opening, said flow control member comprising a resilient flat metal plate having a plurality of interfingering strips integral therewith, said strips being coplanar with each other and with said plate and spaced apart in their undeformed condition and defining between them a zigzag slot, said strips on each side of said slot having the configuration of a straight series of sawteeth.
Claim 3
Dependent Claim
92 words
A fluid transmitting element for increasing vapor-liquid contact, said element having at least one flow opening therethrough, a flow control member disposed in said opening, said flow control member comprising a resilient flat metal plate having a plurality of interfingering strips integral therewith, said strips being coplanar with each other and with said plate and spaced apart in their undeformed condition, and means preventing movement of said strips out of the plane of the plate in one direction, said last-named means comprising rod means secured to the plate and underlying said strips.
Claim 4
Dependent Claim
92 words
A fluid transmitting element for increasing vapor-liquid contact, said element having at least one flow opening therethrough, a flow control member disposed in said opening, said flow control member comprising a resilient flat metal plate having a plurality of interfingering strips integral therewith, said strips being coplanar with each other and with said plate and spaced apart in their undeformed condition, and means preventing movement of said strips out of the plane of the plate in one direction, said last-named means comprising rod means secured to the plate and underlying said strips.
