Preferably the difference between the
number ofjets should one.
The number jets, whether stationary or
rotating, purely arbitrary; but since the
conducting fluid directed from one com-
35 partment into the other the aggregate amount
normally discharged from the compartments
should approximately equal. such means
the distances between the jets each set are
made the greatest possible and hurtful short-
55 circuits are avoided.

fluid required maintain them. circuit-controller, the combination

The continuity the jets streams not
