✦ Synopsis


A large number of liquid nitrogen flU systems have been described in the literature which satisfy a wide range of experimental requirements ~'~. There have not, however, been any descriptions of simple flu systems which provide a rapid, precise regulation of the liquid nitrogen level for widely-differing heat loads on the liquid nitrogen container. Such systems are particularly desirable in cases where, for various experimental reasons, the cooling capacity of the liquid nitrogen container must be held constant.
