✦ Synopsis


The Sulzer turbine, with dynamic gas bearings and brake compressor, is an autonomous expansion device which needs neither an external bearing gas supply nor a control system which prevents a leakage of cold process gas out of the refrigeration cycle. The journal bearings consist of three tilting pads," the thrust bearings are of the spirally graved type. An auxilliary magnetic bearing is used for start-up and shut-down. This type of turbine has been used in plants in the range 40 to 1500 W refrigeration output at 4.4 K. They are especially suited for plants where long-time reliability is essential A plant at the Swiss Institute for Nuclear Research (SIN), which is equipped with this kind of turbines, has now more than three years of nearly uninterrupted service. A number of details of this and other gas bearing turbine plants will be discussed.

## Abstract We have found a new ^111^In‐bleomycin complex (BLMC), which has high affinity to tumor, does not bind to transferrin and is stable in vivo. Distribution in animals bearing glioma, hepatoma, or mammary adenocarcinoma at 48 hours showed: the ratios of tumor to blood, brain, heart, lung, l
