Thank you for your leer of 30 January and the spliced
film which arrived separately.
We have not yet subjected the sample splices to a critical
evaluation and I don't think we will be able to do so for another
three weeks. We will certainly advise you of the results of our
tests as soon as they are completed.
If you must proceed in the near future, our present feeling
is that the following are the desirable splice characteristics for
1. Physical lengthwise alignment is important because it
it not desirable to introduce alignment transient errors
(within about 0.003 inches/foot angular error);
2. As much flexibility as can be achieved in the splits
is desired, but the otplice must be sufficiently strong
to withstand the forces we will put on it (normal
operation tension will be about three pounds, but a safe
factor must be applied, of course); and
3. Ability to withstand many flexes is important since
we will subject the film to may bonds.
In all likelihood, your re*ommendatioa-would be satisfactory
but if our requirements are a, little bit unusugi, a nonstandard
splice might be most favorable.
