Abstract
Abstract The specification discloses a pair of valve caps for a phase contacting column in which the valve caps of the pair are linked together underneath the separator plate. The caps may be formed as a single composite unit, as a pair of complete caps for connecting one to another, or as a collection of at least three components which may be assembled to form a composite unit of two caps.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
127 words
A fluid exchange valve device comprising, in combination: a horizontally extending tray portion of a phase contacting column, said tray having at least two spaced aperture means therein; a pair of separated valve caps, each comprising a plate portion disposed above respective ones of said apertures, portions of said plates extending outwardly of said apertures over said tray; connecting means rigidly connecting said plate portions to each other, said connecting means extending below said tray and disposed for substantially vertical movement with respect to said tray, the extent of said movement defining the extent of opening of said valve device by said valve caps, said connecting means including a weakened portion enabling folding of the interconnected valve caps for insertion into position in relation to the tray.
Claim 2
Dependent Claim
127 words
A fluid exchange valve device comprising, in combination: a horizontally extending tray portion of a phase contacting column, said tray having at least two spaced aperture means therein; a pair of separated valve caps, each comprising a plate portion disposed above respective ones of said apertures, portions of said plates extending outwardly of said apertures over said tray; connecting means rigidly connecting said plate portions to each other, said connecting means extending below said tray and disposed for substantially vertical movement with respect to said tray, the extent of said movement defining the extent of opening of said valve device by said valve caps, said connecting means including a weakened portion enabling folding of the interconnected valve caps for insertion into position in relation to the tray.
Claim 3
Dependent Claim
25 words
The combination of claim 1, wherein said weakened portion comprises a deformable fold line extending across said connecting means symmetrically disposed between said plate portions.
Claim 4
Dependent Claim
205 words
A fluid exchange valve device, comprising: a horizontally extending tray portion of a phase contacting column, said tray portion having at least two spaced apertures formed therein; a pair of separated valve caps, each cap comprising a first cap porTion disposed above a respective one of said apertures in at least partial overlapping engagement with one surface of said tray portion in a closed position of said valve device and lying in a plane substantially parallel to the plane of said tray portion; and connecting means connecting each said first portion to the other, said connecting means comprising: a second cap portion connected to said first portion extending through said aperture and disposed for substantially vertical movement with respect to said tray portion, the extent of said movement defining the extent of opening of said valve device by said valve caps, and a third cap portion connected to said second cap portion and disposed adjacent the opposite surface of said tray portion from said first portion, the third portions of each of said caps being connected to each other, said connecting means further comprising at least one foldable and unfoldable portion to permit insertion of said valve caps through said apertures into operative engagement therewith.
Claim 5
Dependent Claim
205 words
A fluid exchange valve device, comprising: a horizontally extending tray portion of a phase contacting column, said tray portion having at least two spaced apertures formed therein; a pair of separated valve caps, each cap comprising a first cap porTion disposed above a respective one of said apertures in at least partial overlapping engagement with one surface of said tray portion in a closed position of said valve device and lying in a plane substantially parallel to the plane of said tray portion; and connecting means connecting each said first portion to the other, said connecting means comprising: a second cap portion connected to said first portion extending through said aperture and disposed for substantially vertical movement with respect to said tray portion, the extent of said movement defining the extent of opening of said valve device by said valve caps, and a third cap portion connected to said second cap portion and disposed adjacent the opposite surface of said tray portion from said first portion, the third portions of each of said caps being connected to each other, said connecting means further comprising at least one foldable and unfoldable portion to permit insertion of said valve caps through said apertures into operative engagement therewith.
Claim 6
Dependent Claim
28 words
A valve device as defined in claim 3, wherein said foldable portion is defined at the junction between said first and second portions each of said valve caps.
Claim 7
Dependent Claim
24 words
A valve as defined in claim 3, wherein said foldable portion is defined at the junction between said third portions of said valve caps.
Claim 8
Dependent Claim
29 words
A valve device as defined in claim 3, wherein said foldable portion is defined at the junction of said second and third portions of each of said valve caps.
Claim 9
Dependent Claim
200 words
A fluid exchange valve device, comprising: a horizontally extending tray portion of a phase contacting column, said tray portion having at least two spaced apertures formed therein; a pair of separated valve caps, each cap comprising a first cap portion disposed above a respective one of said apertures in at least partial overlapping engagement with one surface of said tray portion in a closed position of said valve device and lying in a plane substantially parallel to the plane of said tray portion; and connecting means connecting each said first portion to the other, said connecting means comprising: a second cap portion connected to said first portion extending through said aperture and disposed for substantially vertical movement with respect to said tray portion, the extent of said movement defining the extent of opening of said valve device by said valve caps, and a third cap portion connected to said second cap portion and disposed adjacent the opposite surface of said tray portion from said first portion, the third portions of each of said caps being connected to each other; wherein said first, second and third portions of each said cap comprise portions of a single sheet of valve cap material.
Claim 10
Dependent Claim
200 words
A fluid exchange valve device, comprising: a horizontally extending tray portion of a phase contacting column, said tray portion having at least two spaced apertures formed therein; a pair of separated valve caps, each cap comprising a first cap portion disposed above a respective one of said apertures in at least partial overlapping engagement with one surface of said tray portion in a closed position of said valve device and lying in a plane substantially parallel to the plane of said tray portion; and connecting means connecting each said first portion to the other, said connecting means comprising: a second cap portion connected to said first portion extending through said aperture and disposed for substantially vertical movement with respect to said tray portion, the extent of said movement defining the extent of opening of said valve device by said valve caps, and a third cap portion connected to said second cap portion and disposed adjacent the opposite surface of said tray portion from said first portion, the third portions of each of said caps being connected to each other; wherein said first, second and third portions of each said cap comprise portions of a single sheet of valve cap material.
Claim 11
Dependent Claim
