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.
