814 8148 ing is thought to contain all necessary information in this regard. The greatest value of this invention will be found in its use for the thermo-dynamic conversion of energy. Reference is now made to Figs. 3 and 4, illustrative of the manner in which it is, or may be, so applied. As in the previous figures, a runner provided made up of disks 13 with openings 14 and spokes.15 which, in this case, may be straight.
