MAGNARC ARC LAMP

Sound Head and a heavy duty ped
estal. The booth is roomy, air.
conditioned and modern which
makes for ideal working conditions
for the operator.
Because of its superb perform
ance, this particular protector has
been selected by thousands of ex-
hibitors for use in their theatres.
This protector has ben standard
for many theaters for a period of
years and projects to the screen
the type Of picture favored by the
atre audiences, where a good, clear
steady picture is a major require
ment.
/ Good sound is due to many fac
tors. Super Simplex was one OF
the first mechanisms specifically
designed for sound, and played an
important part in the tremendous
advance of sound reproduction.
The protector mechanism was
designed by a staff of skilled en-
gineers with many years of exper-
ience in designing motion picture
equipment. 1t is manufactured by
the Oldest and largest concern of
its kind in the world. Every part
is made to precision measurements
by men well qualified by long
training. Each part is designed
and manufactured to serve a defin-
lite need. Where required for best
Operation, parts are hardened and
then ground. An outstanding fea-
ture of this protector is the micro
meter focusing device on the lens
mount which prevents backlash
and maintains perfect focus.
The Peerless Magnarc High In
tensity Projection Arc Lamp is
mounted on the protector behind
the sound mechanism. This arc
lamp is the accepted leader in the
field of simplified high intensity
lighting for small, medium and
large theatres. 1t is first choice
with projectionists because of its
mechanical perfection, simplicity
of operation and utmost depend
ability. Changing trends to great
er contrast in modern photography
makes the application of simplified
high intensity projection lighting
essential to perfect presentation
and enhances the entertainment
value of the show.
The Magnarc's unusual mechan-
ical design makes possible fewer
moving parts and decreases the
necessity for frequent repair parts
requirements. The entire negative
feed assembly is mounted back of
the reflector away from the heat
of the arc and the lamp is scientif-
ically ventilated to reduce reflector
breakage to q minimum. The
unique arrangement of individual
feed control mechanism for each
carbon insures wide fiexibility in
using various carbon combinations,
The Peerless Magnarc lamp was
engineered to provide highly ef-
ficient optical system with all nec-
essary outside controls to main
tain an accurate optical alignment
of the reflector and positive and
negative carbons. The entire re-
fiector holder and negative feed
assembly can be swung out Of the
lamp house instantly for inspection
and cleaning without disturbing
the focus Of the reflector.
The projection booth equipment
was installed by National Theatre
Company, Philadelphia, a unit Of
National Standard Projection Sys-
TEN.
The Hertner Hi" Transverter
used in the projection booth, is
designed specifically to supply
properly corrected direct current
for the protector at generator volt
ages of AZ to 48 volts, with just
enough resistance in each arc cir.

This transverter gives satisfac-
