Helium Gas Recovery Systems,. Where liquid helium is bought out, it is a matter of returning the helium gas in cylinders to the supplier. There may be an economic advantage in returning the gas at a low level of impurity, and in this case what is said below about purification will be relevant. The owner of a liquefier will wan

For straightforward experiments there may be a case for enclosing a container for liquid helium in a radiation shield and an outer vessel within which a high vacuum can be maintained. (See Crof

The energy stored in a compressed gas may be considerable — in contrast with the case of a compressed liquid — and mechanical failure may have such serious consequences that the following steps should be followed scrupulously, however strong the temptation to tak
