Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
78 words
A device for separating vapor phase fluid from a flowing liquid, including a body providing a flow path for the liquid in which centrifugal forces are utilized for a release of vapor phase fluid with a directed escape thereof through a vapor phase flow passage to a vapor outlet, a separate vapor flow passage in said body leading to said outlet, and means utilizing vapor flow through one of said passages to induce flow in the other passage.
Claim 2
Independent Claim
78 words
A device for separating vapor phase fluid from a flowing liquid, including a body providing a flow path for the liquid in which centrifugal forces are utilized for a release of vapor phase fluid with a directed escape thereof through a vapor phase flow passage to a vapor outlet, a separate vapor flow passage in said body leading to said outlet, and means utilizing vapor flow through one of said passages to induce flow in the other passage.
Claim 3
Dependent Claim
38 words
A device according to claim 1, wherein the first said flow passage includes venturi means and wherein said separate flow passage communicates with said first flow passage in position to be evacuated by flow through said venturi means.
Claim 4
Dependent Claim
88 words
A device according to claim 1, wherein said body provides a liquid inlet and an internal helical path terminating in a discharge opening at one end thereof, the first said flow passage forming venturi means centrally of said helical path through which vapor phase fluid released from liquid in said helical path escapes, said separate vapor flow passage opening through said one end of said body and leading to the first said flow passage at a location to have flow therethrough influenced by flow through said venturi means.
Claim 5
Dependent Claim
65 words
A device according to claim 3, wherein said helical flow path is formed in a first chamber in said body, a second chamber therein being longitudinally spaced from the first chamber and connected thereto by said venturi means, said vapor outlet communicating with said second chamBer, and an opening in said body communicating with the first said chamber for admitting liquid to said helical path.
Claim 6
Dependent Claim
41 words
A device according to claim 4, characterized in that said device is useful on and in connection with a vessel, said discharge opening and the said separate flow passage communicating through said one end of said body with the vessel interior.
Claim 7
Dependent Claim
51 words
A device according to claim 5, characterized by a spring loaded valve normally seated in to close said venturi means and opening under released vapor pressure in said first chamber, said separate vapor flow passage extending to said venturi means in position to be closed by said valve when seated therein.
Claim 8
Independent Claim
84 words
A device useful in the liquid filling of vessels to facilitate separation and removal of fluid in the vapor phase, including a body adapted to mount on to be a part of a vessel, said body providing a flow path for in-coming fill liquid in which entrained vapors are inherently released and having an outlet through which such released vapor escapes prior to reaching said vessel, and means utilizing escaping vapor released in said flow path to induce vapor flow from the vessel interior.
Claim 9
Independent Claim
84 words
A device useful in the liquid filling of vessels to facilitate separation and removal of fluid in the vapor phase, including a body adapted to mount on to be a part of a vessel, said body providing a flow path for in-coming fill liquid in which entrained vapors are inherently released and having an outlet through which such released vapor escapes prior to reaching said vessel, and means utilizing escaping vapor released in said flow path to induce vapor flow from the vessel interior.
Claim 10
Dependent Claim
25 words
A device according to claim 7, characterized by pressure responsive valve means intermediate said flow path and said vapor outlet restricting escape of released vapors.
Claim 11
Dependent Claim
86 words
A liquid container of rapid fill characteristics, including a container having a mouth through which it is filled and through which contained liquid is drawn off, a body installed in a closing relation to said mouth and having a liquid flow passage for fill and draw off, means in said passage way imparting a centrifugal effect to in-coming liquid for a release of vapor phase fluids therefrom, and means in said body providing for escape therefrom of released vapor phase fluid prior to reaching said container.
Claim 12
Dependent Claim
86 words
A liquid container of rapid fill characteristics, including a container having a mouth through which it is filled and through which contained liquid is drawn off, a body installed in a closing relation to said mouth and having a liquid flow passage for fill and draw off, means in said passage way imparting a centrifugal effect to in-coming liquid for a release of vapor phase fluids therefrom, and means in said body providing for escape therefrom of released vapor phase fluid prior to reaching said container.
Claim 13
Dependent Claim
26 words
A liquid container according to claim 9, characterized by a valve biased to restrict escape of vapor phase fluids for a pressurizing of the container interior.
Claim 14
Dependent Claim
35 words
A liquid container according to claim 9, characterized by a separate flow passage way intercommunicating said last named means and the vessel interior providing for the escape of vapor phase fluids released in the container.
