THE MUSIC TRADE REVIEW
j / i o t h the time of its first test. Pneumatic No. 2, with the
new packing, stood up over % the time.
Two hours later another test. Pneumatic No. 1, still
I/ioth. Pneumatic No. 2 stood up three-quarters as long-
as the first test—-a 50% improvement on second test.
Twenty-four hours later Pneumatic No. 1 was still i/ioth.
But Pneumatic No. 2 had returned to highest efficiency—
st^ood up the full time of its very first test.
What is the conclusion?
That this new packing
automatically takes up any loosening of the pneumatic due
to shrinkage—preserving the vacuum at its highest point of
efficiency automatically.
