Abstract
Abstract In order to avoid the sloshing of liquid within a container caused by movement of the container, the single bulk volume of the liquid is retained in the form of a plurality of separated mini-volumes. This is accomplished by providing a chamber formed by upper and lower plates and an interconnecting sidewall. A plurality of elongated, adjacent mini-chambers are provided within the chamber aligned in side-by-side relationship with the sidewall. The mini-chambers are formed by a honeycomb medium of acoustical material having one end sealed closed. The medium has no measurable magnetic susceptability and is formed of a paper material treated with a heat resistant phenolic resin. When placed within an insulated housing including isothermal shields, the chamber is useful in cryogenic applications such as, for example, storing liquid helium.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
153 words
Anti-slosh apparatus for cryogenic containers of the type having an inner liquid chamber and an outer insulating housing, comprising: a bottle shaped container having substantially vertical continuous sidewalls defining said inner liquid chamber located inside said insulating housing, a top closure plate connected to said vertical sidewalls, a bottom closure plate connected to said vertical sidewalls, inlet-outlet means connected through said top closure plate and extending through said insulating housing forming a passageway into said inner liquid chamber, cellular anti-sloshing means comprising a plurality of individual mini-chambers inside said inner liquid chamber formed as a honeycomb core sealed closed at said bottom closure plate, and each said individual honeycomb shaped mini-chamber being formed as an independent and isolated vertical container open only at the top and isolated from adjacent mini-chambers so that tilting and sloshing of the liquid in each mini-chamber is independent of and unrelated to tilting and sloshing in adjacent mini-chambers.
Claim 2
Dependent Claim
153 words
Anti-slosh apparatus for cryogenic containers of the type having an inner liquid chamber and an outer insulating housing, comprising: a bottle shaped container having substantially vertical continuous sidewalls defining said inner liquid chamber located inside said insulating housing, a top closure plate connected to said vertical sidewalls, a bottom closure plate connected to said vertical sidewalls, inlet-outlet means connected through said top closure plate and extending through said insulating housing forming a passageway into said inner liquid chamber, cellular anti-sloshing means comprising a plurality of individual mini-chambers inside said inner liquid chamber formed as a honeycomb core sealed closed at said bottom closure plate, and each said individual honeycomb shaped mini-chamber being formed as an independent and isolated vertical container open only at the top and isolated from adjacent mini-chambers so that tilting and sloshing of the liquid in each mini-chamber is independent of and unrelated to tilting and sloshing in adjacent mini-chambers.
Claim 3
Dependent Claim
21 words
The apparatus of claim 1 wherein said means for limiting sloshing are formed of a material having no measurable magnetic susceptability.
Claim 4
Dependent Claim
23 words
The apparatus of claim 1 wherein said means for limiting sloshing are formed of a paper material treated with a heat-resistant, phenolic resin.
Claim 5
Dependent Claim
22 words
The apparatus of claim 1 including: at least one isothermal shield mounted between said inner liquid chamber and said outer insulating housing.
Claim 6
Dependent Claim
23 words
The apparatus of claim 4 including: insulating material between said inner liquid chamber and said shield and between said shield and said housing.
Claim 7
Dependent Claim
15 words
The apparatus of claim 5 including: a stabilizer member connected to said bottom closure plate.
Claim 8
Dependent Claim
27 words
The apparatus of claim 6, including: a neck portion connected to said top closure plate defining a fluid communication port between said chamber and outside said housing.
Claim 9
Dependent Claim
146 words
A cryogenic liquid receptacle having an anti-sloshing apparatus therein, comprising: an enclosed housing; at least one isothermal shield mounted within said housing; a chamber formed by first and second spaced apart members interconnected by a sidewall, said chamber being mounted within said shield; an insulating material between said chamber and said shield and between said shield and said housing; a stabilizer connected to said first member and extending in a first direction; a neck portion connected to said second member and extending outside said housing in a second direction, said neck portion defining a fluid communication port extending from inside said chamber to outside said housing; and a plurality of elongated, adjacent mini-chambers aligned in side-by-side relationship with said sidewall, said mini-chambers having one end adjacent said first member sealed closed and a second end open and extending toward said second member forming individual liquid containers.
Claim 10
Dependent Claim
146 words
A cryogenic liquid receptacle having an anti-sloshing apparatus therein, comprising: an enclosed housing; at least one isothermal shield mounted within said housing; a chamber formed by first and second spaced apart members interconnected by a sidewall, said chamber being mounted within said shield; an insulating material between said chamber and said shield and between said shield and said housing; a stabilizer connected to said first member and extending in a first direction; a neck portion connected to said second member and extending outside said housing in a second direction, said neck portion defining a fluid communication port extending from inside said chamber to outside said housing; and a plurality of elongated, adjacent mini-chambers aligned in side-by-side relationship with said sidewall, said mini-chambers having one end adjacent said first member sealed closed and a second end open and extending toward said second member forming individual liquid containers.
Claim 11
Dependent Claim
