Ex-Cell-0 Precision Utilized in Construction
It has been announced recently that the w o rld ’s
first transoceanic telephone cable w ill reach across
the Atlantic to connect United States and C anada
with
G re a t Britain. The project w ill
be
a joint
undertaking o f American Telephone and T elegraph
Com pany, the British Post O ffice , which is respon­
sible fo r telephone service in G re a t Britain, and the
C anadian
Overseas Telecommunication C o rp o ra ­
tion. The cable w ill be 2 ,0 0 0 miles long, w ill carry
36 conversations simultaneously, and w ill take three
years to complete.
It was necessary to solve many problem s b e fo re
such an ambitious project could be started. For
exam ple, the voice has to be stepped up a t freq ue n t
intervals in travelling so g re a t a distance. A m ajor
problem was the developm ent o f am plifiers that
could be enclosed in the cable and could o p e ra te
in the depths o f the ocean w ithout any maintenance.
Such devices have been d eve lo pe d and have been
in use betw een Key W est, Florida, and H avana,

a structure that is built into the cable and a pp ea rs
as a ta pe rin g bulge. This construction allows the
am plifiers to pass through the cable ship's g e a r
along with the cable.
The Precision Products Division o f Ex-C ell-O is
m anufacturing the steel rings that p ro tect the a m p li­
fiers. Each inner ring is a bo ut % o f an inch long, 1 Vl

Extra parts are run with each lot because a certain
percentage must be inspected fo r hardness and
these are discarded because the test renders them
unacceptable.
The outside d ia m e te r o f the inner rings and the
inside d ia m e te r o f the outer rings are held to total
limits o f .0 0 0 4 ". This is a tough job, especially on
the outer rings because they are very thin and
easily distorted. Ex-C ell-O holds these limits con­
