American Cinematographer - December 1970 - 79

thought about the fairly rough-andready treatment that motion picture
equipment is sometimes prone to and
the environment in which it works. And
we know that in hazardous conditions
the danger of accidents involving lenses
is fairly high. So the Cooke Varotal is
designed to withstand maximum shock.
The Cooke Varotal can also withstand
extremes of temperature and humidity.
Mechanics are on the principle of rolling
action, not sliding friction, which means
they are free from wear and backlash for
the Cooke VarotaTs entire working life.
It should be emphasized that the
model of the new Cooke Varotal lens
shown at Photokina was strictly a proto¬
type. Questions as to its general avail¬
ability on the market brought the
answer that "it is currently in produc¬
tion," but no specific delivery dates
could be quoted. ■

PICKER SUBSIDIARY HAS NEW
35MM ANALYTICAL PROJECTOR
An analytical projector for 35mm
cinefilm used in visual presentations,
training, simulators and other instruc¬
tion is being marketed by the Vertex
subsidiary of Picker Corporation. What
the company calls "flickerless" slow
motion, stop motion and instantaneous
reverse are selected by remote control.
In general, the unit provides the
analytical features for 35mm cinefilm
that, until now, had only been available
in machines useing 16mm film, Vertex
said.
The design incorporates a Genevatype film transport mechanism, threeelement lens, interchangeable projection
lamps up to 1200 watts, and solid state
circuitry. According to the manufac¬
turer, these features result in viewing at
any frame rate without flickering, silent
operation, optimum image definition,
and ease of operation. A system of
sensing switches and photo cells insures
that film cannot be damaged, the
company said.
The machine accepts up to 1200 feet
of film on reels and 500 feet of film on
cores. The unit uses a separate projec¬
tion screen and with a 1200-watt lamp
is "ideal" for large audience viewing,
Vertex said. With a 500-watt lamp, the
silent operation makes the unit excel¬
lent for small group viewing. The
remote control provides every operation
and viewing control including focus.

CALVIN PRODUCTIONS.
The "revolutionary" communica¬
tions company.
It began in the '30's, when CALVIN
pioneered the national acceptance and
widespread use of the 16mm film
format for commercial purposes.
Produced the first 16mm sound film
in full color...developed one of the
first
portable
16mm
sync-sound
magnetic recorders.
Today, CALVIN continues to revo¬
lutionize the film industry with new

ideas and advanced technology, using
the best equipped production and
lab facilities anywhere.
Like one of the most sophisticated
sound mixing systems. And two of the
largest sound stages -one a "cyclorama" - between the coasts.

friend with any film communications
assignment, write for our free booklet
"So You Want To Make A Film."
It may revolutionize the approach
to your next film.
