HIGH
Pneumatic Hose-Engineering knowledge is important to the work
of the hygiene staff. This apparatus is used to suck up powdered
ceramic materials from freight cars to large storage silos. The
workman is thus protected from dust which would be unavoidable
if the powdered material had to be shoveled.

NATURE'S EXTREMES NOW
AVAILABLE TO SCIENCE
  Testing equipment ten miles up in
the sky without ever leaving the
ground is now possible in this new
turbo pump altitude test chamber
at General Electric's Aircraft Gas
Turbine Division facilities at Lynn,
Mass.
  This chamber is one of the many
testing facilities used to test equip-
ment under the severest conditions
which could be encountered in ac-
tual  flight. Simulated  altitudes
over 60,000 feet can be obtained as
well as simulated aircraft climb
rates in excess of 20,000 feet per
minute and climb rate angles as high
as 60 degrees.
  Used primarily for testing reheat
(afterburner) fuel pumps for jet
engines under varied conditions and
altitudes, this chamber has a vol-
ume of approximately 950 cubic
feet and can accommodate a 470
gallon capacity fuel tank. Engineers
can observe pump operations under
all conditions of altitude by watch-
ing through the observation ports
provided in the sides of the chamber.
  The entire end of the chamber
can be removed to permit the instal-
lation of larger equipment to be
tested under altitude conditions.
